Background

With the development of internet technology, clients providing various functions to users are becoming more and more popular. For example, a user may view video through a client for playing video.

In the related art, when playing a video, a client may first obtain a video file of a target video to be played. Then, the client may decode the video file of the target video through the first decoding module to obtain each video frame included in the target video. Meanwhile, the client can decode the video file of the target video through the second decoding module so as to acquire the actual aspect ratio of the target video. When the client acquires the video frames contained in the target video through the first decoding module, if the actual aspect ratio of the target video is not acquired currently, the client plays the video frames contained in the target video according to the preset aspect ratio. Subsequently, when the actual aspect ratio is obtained through the second decoding module, the client switches to playing the video frame contained in the target video according to the actual aspect ratio.

However, switching from playing the video frames contained in the target video at the preset aspect ratio to playing the video frames contained in the target video at the actual aspect ratio may cause distortion of the picture content in the video picture displayed by the client (e.g., the characters in the picture are elongated, etc.), reduce the video playing quality, and affect the viewing experience of the user.

Detailed Description

The technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention.

In the related art, a process of switching from playing video frames included in a target video according to a preset aspect ratio to playing video frames included in a target video according to an actual aspect ratio may cause distortion of picture content in a displayed video picture, reduce video playing quality, and affect viewing experience of a user.

In order to solve the above problem, an embodiment of the present invention provides a video playing system, which may include: a client and a server, wherein:

the client sends a request message carrying the video identification of the target video to the server.

When receiving the request message, the server acquires playing information corresponding to the video identifier of the target video, takes the playing information as target playing information, and sends the target playing information to the client. Wherein the target play information contains aspect ratio information indicating an actual aspect ratio of the target video and a storage address.

When receiving the target playing information, the client acquires a video file of the target video according to the storage address, and plays the target video according to the actual aspect ratio indicated by the aspect ratio information and the video file.

Based on the video playing system provided by the embodiment of the invention, the client firstly acquires the actual aspect ratio and the storage address of the target video, and correspondingly, when the client acquires the video file of the target video according to the storage address, the client already acquires the actual aspect ratio of the target video. Furthermore, the client can play the target video based on the actual aspect ratio of the target video, so that the situation that the video is played according to the preset aspect ratio due to the fact that the actual aspect ratio of the target video is not obtained in time can be avoided to a certain extent, further, deformation of picture content in a played video picture is avoided to a certain extent, video playing quality can be improved, and viewing experience of a user is improved.

For other embodiments of the video playback system described above, reference may be made to the following description of method embodiments with respect to clients and servers.

Referring to fig. 1, fig. 1 is a flowchart of a video playing method according to an embodiment of the present invention, where the method may be applied to the video playing system, and the method may include the following steps:

s101: the client sends a request message carrying the video identification of the target video to the server.

S102: and when the server receives the request message, acquiring playing information corresponding to the video identifier of the target video as target playing information.

Wherein the target play information contains aspect ratio information indicating an actual aspect ratio of the target video and a storage address.

S103: and the server sends the target playing information to the client.

S104: and when receiving the target playing information, the client acquires the video file of the target video according to the storage address.

S105: the client plays the target video according to the video file according to the actual aspect ratio indicated by the aspect ratio information.

Based on the video playing method provided by the embodiment of the invention, the client firstly acquires the actual aspect ratio and the storage address of the target video, and correspondingly, when the client acquires the video file of the target video according to the storage address, the client already acquires the actual aspect ratio of the target video. Furthermore, the client can play the target video based on the actual aspect ratio of the target video, so that the situation that the video is played according to the preset aspect ratio due to the fact that the actual aspect ratio of the target video is not obtained in time can be avoided to a certain extent, further, deformation of picture content in a played video picture is avoided to a certain extent, video playing quality can be improved, and viewing experience of a user is improved.

For step S101, the client may be used to play the video, for example, the client may be a system player of an android system, and the client may be installed on a different device, for example, a mobile phone, a computer, a television, and the like.

When the user needs to watch the video, the user can input a playing instruction for the video to be played (i.e. the target video of the embodiment of the invention) to the client. Correspondingly, the client can receive the playing instruction input by the user, further determine the video identification of the target video indicated by the playing instruction, and send a request message carrying the video identification of the target video to the server. The video identification of the target video may be the name of the target video.

For step S102 and step S103, the server may receive the request message sent by the client, and extract the video identifier (i.e., the video identifier of the target video) carried in the received request message. Then, the server can acquire playing information corresponding to the video identification of the target video as target playing information.

The server may store the playing information of a plurality of videos locally, and for each video, the server may acquire the playing information of the video in the following manner.

In an implementation, referring to fig. 2 on the basis of fig. 1, before step S102, the method may further include the steps of:

s106, the server acquires each original video frame corresponding to the target video.

S107, the server encodes each acquired original video frame to obtain a video file of the target video.

S108, the server stores the video file of the target video to the content distribution network, and correspondingly stores the video identification and playing information of the target video to the server.

The playing information of one video may include: aspect ratio information representing an actual aspect ratio of the video, a storage address of the video, a resolution of the video, a video format of the video, and the like.

The server may acquire each original video frame corresponding to the target video, where the original video frame corresponding to the target video is a video frame when the target video is produced, for example, a video frame obtained by capturing by the image capturing device.

Since the resolution, aspect ratio and video format of each original video frame corresponding to the target video are fixed, different playing requirements of the user cannot be met, for example, the video format of the original video frame of the target video is in "AVI" format, and the user may need to play the target video in "HDR" format.

Therefore, in order to meet different playing requirements of users, the server can encode the original video frames corresponding to the target video to obtain the video files of the target video meeting the different playing requirements. The play requirement may include: preset resolution, preset aspect ratio, preset video format, etc. For example, the server may encode each original video frame corresponding to the target video according to a preset resolution of 1080P, a preset aspect ratio of 16:9, a preset video format of "AVI" format, to obtain a video file of the target video, where the resolution of the video file is 1080P, the aspect ratio of 16:9, and the video format of "AVI" format. The server may further encode each original video frame corresponding to the target video according to a preset resolution of 720P, a preset aspect ratio of 16:9, a preset video format of "AVI" format, to obtain a video file of the target video, where the resolution of the video file is 720P, the aspect ratio of 16:9, and the video format of "AVI" format.

After encoding the video file of the target video, the video file of the target video may be stored to a preset storage location, for example, to a preset database, for example, dis (Remote Dictionary Server, remote dictionary service), or may be stored to the CDN (Content Delivery Network ). Furthermore, the server may determine the playing information of the target video, and store the video identifier of the target video and the playing information to the server, that is, record the video identifier of the target video and the corresponding playing information locally in the server.

In another implementation, the servers may include an encoding server and a management server. The encoding server can acquire each original video frame corresponding to the target video, and encode the original video frame corresponding to the target video to obtain a video file of the target video. Further, the encoding server may store the video file of the target video to a preset storage location, for example, store the video file of the target video to a content distribution network. Further, the encoding server may determine playback information of the target video and send the video identification and the playback information of the target video to the management server.

The management server can receive the video identification and the playing information of the target video and store the video identification and the playing information of the target video to the local. Subsequently, the management server can receive the request message sent by the client and acquire the target playing information according to the video identifier of the target video carried in the request message.

Further, the server may send target play information of the target video to the client.

For step S104, the client may receive the target play information sent by the server. Then, based on the received target play information, the actual aspect ratio of the target video and the video file of the target video are acquired.

The target play information contains aspect ratio information indicating the actual aspect ratio of the target video. In one implementation, the aspect ratio information may be an actual aspect ratio of the target video, and the client may directly obtain the actual aspect ratio of the target video and obtain the video file of the target video according to the storage address.

In another implementation, the aspect ratio information may be the actual width and the actual height of the target video. The client can calculate the ratio of the actual width to the actual height of the target video to obtain the actual aspect ratio of the target video, and acquire the video file of the target video according to the storage address.

In one embodiment of the invention, the client may include a rendering layer and a decoding layer, when receiving the target playing information, the client may obtain the video file of the target video according to the storage address through the decoding layer, and meanwhile, the client calculates the ratio of the actual width to the actual height of the target video through the rendering layer to obtain the actual aspect ratio of the target video, and then, the client may not decode the video file to obtain the actual aspect ratio after obtaining the video file of the target video, i.e. may obtain the actual aspect ratio of the target video in advance, so that the client may already obtain the actual aspect ratio of the target video when obtaining the video file of the target video, and then may play the target video according to the actual aspect ratio, thereby improving the video playing quality and improving the user experience.

If the video file of the target video is stored in the preset database, the storage address of the target video represents the storage position of the video file of the target video in the preset database. The client can acquire the video file of the target video under the storage address in the preset database.

If the video file of the target video is stored in the content distribution network, the storage address of the target video indicates the storage location of the video file of the target video in the content distribution network.

Accordingly, step S104 may include the steps of: the client obtains a video file of the target video at a storage address in the content distribution network.

Based on the above processing, the content distribution network includes a plurality of cache servers for storing video files, the cache servers are distributed to areas or networks where client accesses are relatively concentrated, and the client can acquire video files from the cache server closest to the client, so that the efficiency of the client for acquiring video files can be improved.

In one embodiment of the present invention, referring to fig. 3, based on fig. 1, step S105 may include the steps of:

s1051: and the client decodes the video file to obtain a video frame contained in the target video.

S1052: the client determines a display area of the target video in the play window as a target display area based on the display aspect ratio of the play window of the client and the actual aspect ratio indicated by the aspect ratio information.

S1053: and the client plays the video frames contained in the target video in the determined target display area.

The play window of the client is a view of a video frame for displaying the target video. Since the display aspect ratio of the play window may be different from the actual aspect ratio, the client needs to determine a target display area for playing the target video from the play window.

In one implementation, the client may include a decoding layer and a rendering layer, the client may decode the video file through the decoding layer to obtain a video frame included in the target video, and determine, through the rendering layer, a target display area of the target video in a play window of the client based on a display aspect ratio of the play window and an actual aspect ratio of the target video. Furthermore, the client may render, through the rendering layer, the video frames contained in the target video in the determined target display area based on the video frames contained in the target video, so as to play the video frames contained in the target video in the target display area.

In one embodiment of the present invention, referring to fig. 4, on the basis of fig. 3, step S1052 may include the steps of:

s10521: the client determines whether the display aspect ratio of the play window and the actual aspect ratio represented by the aspect ratio information are the same.

S10522: if the display aspect ratio is the same as the actual aspect ratio, the client determines that all display areas in the playing window are display areas of the target video and serve as target display areas; if the display aspect ratio is different from the actual aspect ratio, the client determines a display area with the aspect ratio being the actual aspect ratio from the playing window, and obtains the display area of the target video in the playing window as the target display area.

The client may determine whether the display aspect ratio and the actual aspect ratio of the play window are the same, and if the display aspect ratio and the actual aspect ratio are the same, which indicates that playing the target video according to the display aspect ratio does not cause distortion of the picture content in the video picture, the client may determine that all display areas in the play window are target display areas of the target video.

If the display aspect ratio is not the same as the actual aspect ratio, indicating that playing the target video at the display aspect ratio results in distortion of the picture content in the video picture, the client may determine a target display area having an aspect ratio that is the actual aspect ratio from the play window. Since the aspect ratio of the target display area is the actual aspect ratio, playing the target video in the target display area does not cause distortion of the picture content in the video picture.

In one implementation, where the width of the target display area (which may be referred to as the target width) is the same as the width of the playback window, the client may calculate the height of the target display area (which may be referred to as the target height) according to the actual aspect ratio of the target video and the width of the playback window. Then, the client may determine the line segments of the target height on the two longitudinal edges of the play window, respectively, and the two endpoints of one line segment are located on the same straight line with the endpoints of the other line segment, respectively. Furthermore, the client may connect an end point of one line segment with an end point corresponding to another line segment, and the obtained quadrangular region is a target display region.

In another implementation, in the case where the height of the target display area (i.e., the target height) is the same as the height of the play window, the client may calculate the width of the target display area (i.e., the target width) according to the actual aspect ratio of the target video and the height of the play window. Then, the client may determine the line segments of the target width on the two lateral edges of the play window, respectively, and the two endpoints of one line segment are located on the same straight line with the endpoints corresponding to the other line segment, respectively. Furthermore, the client may connect an end point of one line segment with an end point corresponding to another line segment, and the obtained quadrangular region is a target display region.

In addition, when the client displays the video picture of the target video in the target display area, the preset content may be displayed in other display areas than the target display area. For example, the client may display a full black screen in other display areas than the target display area, or may display related information of the target video, such as a profile of the target video, an identification of other videos of the same type of the target video, or the like, in other display areas than the target display area.

In one embodiment of the present invention, in order to improve the video playing quality, more areas in the playing window display the video frames of the target video, and the width of the target display area may be the same as the width of the playing window, or the height of the target display area may be the same as the height of the playing window.

In one implementation, in order to enable all video frames of the target video to be displayed in the playing window, and more areas in the playing window display video frames of the target video, when the actual width of the target video is greater than the actual height, the width of the target display area may be the same as the width of the playing window. When the actual width of the target video is smaller than the actual height, the height of the target display area may be the same as the height of the play window. When the actual width of the target video is equal to the actual height, the width of the target display area may be the same as the width of the play window, or the height of the target display area may be the same as the height of the play window.

Exemplary, the actual aspect ratio of the target video is 4:3, the display aspect ratio of the playback window is 16:9, and the display width of the playback window is 1280 pixels, and the display height of the playback window is 720 pixels. The actual width of the target video is greater than the actual height, and in the case of maintaining the aspect ratio of the target display area to 4:3, the width of the target display area may be the same as the width of the play window (i.e., 1280 pixels), and the height of the target display area is 960 pixels. At this time, the width of the target display area is the same as the width of the playing window, and the height of the target display area is smaller than the height of the playing window, so that all video frames of the target video can be displayed in the playing window, and more areas in the playing window display video frames of the target video.

The actual aspect ratio of the target video is 2:3, the display aspect ratio of the play window is 16:9, the display width of the play window is 1280 pixels, and the display height of the play window is 720 pixels. The actual width of the target video is smaller than the actual height, and in the case of keeping the aspect ratio of the target display area to be 2:3, the height of the target display area may be the same as the height of the play window (i.e., 720 pixels), and then the width of the target display area is 480 pixels. At this time, the height of the target display area is the same as the height of the playing window, and the width of the target display area is smaller than the width of the playing window, so that all video frames of the target video can be displayed in the playing window, and more areas in the playing window display video frames of the target video.

Based on the above processing, when the width of the target display area is the same as the width of the playing window, the video frame of the target video can be made to fill the playing window transversely, and if the height of the target display area is different from the height of the playing window, the playing window is only required to be filled with the preset content longitudinally. When the height of the target display area is the same as that of the playing window, the playing window can be longitudinally filled with video pictures of the target video, and the width of the target display area is different from that of the playing window, so that the playing window is only required to be filled with preset contents transversely, more areas in the playing window can display video pictures of the target video, the playing quality of the video can be improved, and further the user experience is improved.

In one embodiment of the present invention, when the client plays the target video according to the actual aspect ratio, when the video frame of the target video is displayed in the target display area, and the preset content is displayed in the other display areas except for the target display area, that is, the playing window of the client displays the other content except for the video frame of the target video, the user may need to display the video frame of the target video in all the display areas of the playing window, and the user may input a full-screen playing instruction to the client.

Correspondingly, if a full-screen playing instruction input by a user is received, the client can take all the display areas in the playing window as target display areas of the target video, and play video frames contained in the target video in the target display areas so as to realize full-screen playing of the target video.

Referring to fig. 5, fig. 5 is a flowchart of a video playing method provided in the related art.

In the related art, the client may be a system player of an android system, and when playing the video, the client may first download video content data, that is, obtain a video file of the target video. Then, the client can analyze the video content data through the decoding module to obtain a rendering window position and rendering video content, a source program of the decoding module is stored in a ROM (read only memory) of the electronic device, the rendering window position refers to a target display area of the target video in a playing window of the client, and the rendering video content refers to each video frame contained in the target video. The client decodes the video file through the first decoding module to obtain the actual aspect ratio of the target video, and determines the target display area of the target video in the playing window based on the actual aspect ratio of the target video. And meanwhile, the client decodes the video file through the second decoding module to obtain a video frame contained in the target video.

And playing the video frame contained in the target video in the target display area when the client acquires the video frame contained in the target video through the first decoding module.

The actual aspect ratio of the target video needs to be obtained before the target display area corresponding to the actual aspect ratio is determined, but the actual aspect ratio of the target video and the included video frames are obtained simultaneously in the related art, and therefore, in the related art, it cannot be guaranteed that the rendering window position is preferentially determined before the rendering of the video content is determined, that is, it cannot be guaranteed that the client has already obtained the actual aspect ratio of the target video when obtaining the video frames included in the target video.

And if the target display area of the target video in the playing window is determined based on the actual aspect ratio, playing the video frame contained in the target video in the determined target display area.

When the client acquires the video frames contained in the target video through the first decoding module, if the actual aspect ratio of the target video is not acquired currently, the client determines a target display area of the target video in the playing window according to the preset aspect ratio, and plays the video frames contained in the target video in the determined target display area, namely, the client plays the video frames contained in the target video according to the preset aspect ratio. Subsequently, when the actual aspect ratio is obtained through the second decoding module, the client switches to determining a target display area according to the actual aspect ratio, and plays video frames contained in the target video in the target display area.

Switching from playing the video frames contained in the target video according to the preset aspect ratio to playing the video frames contained in the target video according to the actual aspect ratio can occur in the process of stretching the video pictures from the wrong proportion (i.e. the preset aspect ratio) to the correct proportion (i.e. the actual aspect ratio) in the displayed video pictures of the client, namely, the picture content in the displayed video pictures is deformed, the video playing quality is reduced, and the viewing experience of the user is affected.

Referring to fig. 6, fig. 6 is a flowchart of another video playing method according to an embodiment of the present invention.

The original medium is a device used in producing content data (i.e., a target video), for example, an image capturing device used in capturing content data. The encoding server may obtain content data (i.e., each original video frame corresponding to the target video in the foregoing embodiment) in the original medium, encode the content data by using the encoder to obtain a plurality of encoded content data (i.e., video files of the target video in the foregoing embodiment) meeting various playing requirements, store the encoded content data to the CDN, and store encoding information (i.e., resolution, aspect ratio, and video format of the content data) of the content data locally.

Then, the encoding server stores the content-related information (i.e., the play information in the foregoing embodiment) and the content address (i.e., the storage address in the foregoing embodiment) to the play data background, that is, the management server in the foregoing embodiment. Namely, the encoding server acquires each original video frame corresponding to the target video, and encodes the original video frame corresponding to the target video to obtain a video file of the target video. The encoding server stores the video file of the target video to the CDN, and correspondingly stores the video identification and playing information of the target video to the management server.

The client sends a request message carrying the video identification of the target video to the management server. The management server, upon receiving the request message, transmits the content address data (i.e., the storage address in the foregoing embodiment) and the content data width-height information (i.e., the aspect ratio information in the foregoing embodiment) to the client. That is, the server transmits the target play information to the client, the target play information including aspect ratio information indicating an actual aspect ratio of the target video and a storage address.

The client may be an android system player, the player decoding layer is a decoding layer contained in the client, and the player rendering layer is a rendering layer contained in the client. The client can receive the content address data through the decoding layer, acquire the content data from the CDN according to the content address data, and decode the content data to obtain decoded video content. The client obtains the video file of the target video from the CDN according to the storage address through the decoding layer, and decodes the video file of the target video to obtain the video frame contained in the target video.

The client may also determine the video window (i.e. the target display area in the foregoing embodiment) according to the width-height information of the content data through the rendering layer, that is, the client may determine the target display area of the target video in the play window through the rendering layer based on the actual aspect ratio of the target video and the display aspect ratio of the play window of the client.

Furthermore, the client may play based on the decoded video content and the video window, that is, the client may render in the target display area based on the video frames contained in the target video to play the target video.

Based on the above processing, the actual aspect ratio of the target video has been determined at the time of encoding the video file from which the target video is obtained, and therefore, the server can record the actual aspect ratio of the target video in the play information of the target video. When the client acquires the storage address of the target video, the client can acquire the playing information of the target video. Accordingly, when the client acquires the video file of the target video according to the storage address, the actual aspect ratio of the target video is already acquired, that is, the actual aspect ratio of the target video may be acquired in advance. Furthermore, the client can play the target video based on the actual aspect ratio of the target video, decoding the video file after the video file of the target video is acquired is not needed, and the actual aspect ratio of the target video is obtained, so that the target display area of the target video can be determined in the play window earlier, the situation that the video is played according to the preset aspect ratio due to the fact that the actual aspect ratio of the target video is not acquired in time can be avoided to a certain extent, further, deformation of picture content in a played video picture is avoided to a certain extent, video playing quality can be improved, and the target display area of the target video in the play window is determined based on the actual aspect ratio of the target video before the first video frame of the target video is played, further, the target video is played according to the actual aspect ratio of the target video, the phenomenon that the display content in the video picture is deformed can not be seen by a user, and user experience is improved.

Referring to fig. 7, fig. 7 is a flowchart of another video playing method according to an embodiment of the present invention.

The client may perform download parsing on the video metadata (i.e., the target playing information in the foregoing embodiments) while playing the video. That is, the client sends a request message to the server carrying the video identification of the target video. The server sends the target playing information to the client when receiving the request message. The client analyzes the target playing information to obtain the aspect ratio information and the storage address which represent the actual aspect ratio of the target video.

The client may determine the rendering window position (i.e. the target display area in the previous embodiment) based on the parsed aspect ratio information, i.e. the client determines the target display area of the target video in the play window by based on the actual aspect ratio of the target video and the display aspect ratio of the play window of the client.

The client may then download the video content data (i.e., the video file of the target video in the previous embodiment), i.e., the client retrieves the video file of the target video from the CDN according to the storage address. The client can also analyze the video content data through a decoding layer to obtain video rendering content, and a source program of the decoding layer is stored in a ROM of the electronic device. The client decodes the video file of the target video to obtain the video frame contained in the target video.

Further, the client may play based on the rendering window position and the rendering video content, that is, the client may render in the target display area based on the video frames contained in the target video to play the target video.

Based on the above processing, the client may first acquire the actual aspect ratio and the storage address of the target video, and correspondingly, when the client acquires the video file of the target video according to the storage address, the client already acquires the actual aspect ratio of the target video. Furthermore, the client can play the target video based on the actual aspect ratio of the target video, so that the situation that the target video is played according to the preset aspect ratio due to the fact that the actual aspect ratio of the target video is not obtained in time can be avoided to a certain extent, further, deformation of picture content in a played video picture is avoided to a certain extent, video playing quality can be improved, and before the first video frame of the target video is played, the target display area of the target video in the playing window is determined based on the actual aspect ratio of the target video, further, the target video is played according to the actual aspect ratio of the target video, and further, the phenomenon that the displayed content in the video picture is deformed is not seen by a user, and user experience is improved.
