The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
Fig. 1 is a schematic diagram of an application scenario of a video playing method according to some embodiments of the present disclosure.
The video playing method provided by some embodiments of the present disclosure is generally executed by a terminal device. The terminal device may be hardware or software. When the terminal device is hardware, it may be various electronic devices supporting video processing, including but not limited to a smart phone, a tablet computer, an electronic book reader, a vehicle-mounted terminal, and the like. When the terminal device is software, the terminal device can be installed in the electronic devices listed above. It may be implemented, for example, as multiple software or software modules to provide distributed services, or as a single software or software module. And is not particularly limited herein.
In the application scenario shown in fig. 1, an execution subject of the video playing method may be a video-class application installed on the smartphone 100. The user can watch videos through the smart phone 100 and the video-type application installed on the smart phone. In this process, as an example, the video class application may first read the native aspect ratio 102 of the target video 101 obtained from the video file of the target video 101. In practice, various attribute information such as the size and aspect ratio of a video is often contained in a video file. The video-class application can directly read such information of the target video 101. On this basis, it can be determined whether the aspect ratio 102 is consistent with the aspect ratio 104 in the video playing information 103 corresponding to the target video 101, and the video playing information 103 is issued by the server. The video playback information 103 may be intermediate information related to video playback. As an example, information such as aspect ratio may be included. In response to determining that the aspect ratio 102 is inconsistent with the aspect ratio 104 in the video playing information 103, processing the target video based on the aspect ratio and the aspect ratio of the screen of the video playing device to obtain a processed video; and playing the processed video. For example, the native aspect ratio is 2:1, and the screen aspect ratio is 16:9, in which case the width of the target video may be clipped to obtain a processed video with an aspect ratio of 16: 9.
With continued reference to fig. 2, a flow 200 of some embodiments of a video playback method according to the present disclosure is shown. The video playing method comprises the following steps:
step 201, obtaining the aspect ratio of the target video from the video file of the target video.
In some embodiments, the executing subject of the video playing method may obtain the self aspect ratio of the target video from the video file of the target video. The video file of the target video can be stored locally in the execution main body or can be stored in other electronic equipment in communication connection. When stored in other electronic devices, the execution body may acquire the video file in a limited or wireless manner. In practice, various attribute information of the target video may be included in the video file of the target video. For example, the size, aspect ratio, resolution, etc. of the video. The execution subject of the video playing method (e.g., the video-class application in fig. 1) can directly read this information. The target video may be any video. The target video can be determined through specification or screening under certain conditions. For example, a currently playing video may be determined as the target video. As another example, a video stored at a video playback address acquired by the execution subject may be determined as the target video. Wherein the aspect ratio may refer to a ratio between a width and a height of the video image.
Step 202, determining whether the aspect ratio of the video playing information corresponding to the target video is consistent with the aspect ratio of the video playing information corresponding to the target video, and issuing the video playing information by the server.
In some embodiments, when the video file is stored in the server, the execution main body may receive a video playing address (URL) issued by the server. In addition, the video playing information sent by the server can be received. As an example, the video playing information may include information such as aspect ratio. On this basis, the execution subject may determine whether the aspect ratio thereof coincides with the aspect ratio in the video play information corresponding to the target video. If not, execution may continue to step 203. If the video playing information is consistent with the target video, optionally, the target video can be directly played according to the aspect ratio (or the aspect ratio of the target video) in the video playing information.
In some optional implementations of some embodiments, the execution body may upload aspect ratio comparison information to a server of the communication connection. The aspect ratio comparison information is used for representing whether the aspect ratio of the aspect ratio is consistent with the aspect ratio in the video playing information corresponding to the target video. Therefore, the server can perform corresponding marking so as to adjust the aspect ratio in the video playing information subsequently.
Step 203, in response to determining that the aspect ratio of the target video is inconsistent with the aspect ratio in the video playing information, processing the target video based on the aspect ratio of the target video and the aspect ratio of the screen of the video playing device to obtain a processed video.
In some embodiments, in response to determining that the self aspect ratio is not consistent with the aspect ratio in the video playing information, as an example, the execution subject may crop the target video based on the self aspect ratio and the screen aspect ratio of the video playing device, thereby obtaining the processed video. For example, the native aspect ratio is 2:1, and the screen aspect ratio is 16:9, in which case the width of the target video may be cropped to obtain a processed video with an aspect ratio of 16: 9.
And step 204, playing the processed video.
In some embodiments, the aspect ratio of the processed video to the screen is adapted, and the execution subject can play the processed video.
One of the above-described various embodiments of the present disclosure has the following advantageous effects: in some scenarios, for example, the aspect ratio of the video is not included in the video playing information, or the video rotation parameter is included in the video playing information, and the like, which may cause the aspect ratio reading failure or the reading error, thereby affecting the normal playing of the video. The aspect ratio issued by the server is verified by comparing the aspect ratio of the video with the aspect ratio issued by the server. Therefore, video compression or amplification caused by server issuing errors can be avoided. And for the condition that the aspect ratio of the video playing device is inconsistent with the aspect ratio issued by the server, processing the target video based on the aspect ratio of the video playing device and the aspect ratio of the screen of the video playing device, and playing the processed video to correct the wrong aspect ratio and realize the normal playing of the video.
With further reference to fig. 3, a flow 300 of further embodiments of a video playback method according to the present disclosure is shown. The video playing method comprises the following steps:
In some embodiments, the execution subject may obtain the self aspect ratio of the target video from the video file of the target video before playing the first preset number of frames of the target video. In practice, the preset number can be set according to actual needs. For example, the preset number may be one, so that subsequent processing may be performed before the first frame to reduce video frames that are not normally played (enlarged or reduced). Compared with the verification at other times, the aspect ratio verification is carried out before the first frame is played, so that the video amplification or compression can be avoided to the maximum extent. In addition, step 201 in those embodiments corresponding to fig. 2 may be referred to for specific implementation of obtaining the aspect ratio of the target video from the video file of the target video, and details are not repeated here.
In some embodiments, the specific implementation of step 302 and the technical effect brought by the implementation may refer to step 202 in the embodiment corresponding to fig. 2, which are not described herein again.
In some embodiments, the execution subject may determine the type of the target video in response to determining that the aspect ratio itself is not consistent with the aspect ratio in the video playback information. According to actual needs, videos can be classified according to different classification standards. For example, videos may be classified according to whether they are horizontal or vertical. As another example, the video may be classified according to the content thereof.
And step 304, processing the target video based on the aspect ratio of the target video, the aspect ratio of the screen of the video playing device and the type of the target video.
In some embodiments, the executing agent may process the target video based on its aspect ratio, the aspect ratio of the screen of the video playback device, and the type of target video determined in step 303. Taking as an example the classification of a video according to whether the video is a horizontal version video or a vertical version video, the processing can be performed according to the following steps:
Of course, for videos classified by other classification criteria, a corresponding mode may be selected for processing such as clipping.
And 305, playing the processed video.
As can be seen from fig. 3, compared with the description of some embodiments corresponding to fig. 2, by determining the type of the video and performing different processing on the video according to different types of the video, the video processing is more targeted and accurate, so as to further ensure the normal playing of the video.
With further reference to fig. 4, as an implementation of the methods shown in the above figures, the present disclosure provides some embodiments of a video playing apparatus, which correspond to those shown in fig. 2, and which may be applied in various electronic devices.
As shown in fig. 4, the video playback apparatus 400 of some embodiments includes: an acquisition unit 401, a comparison unit 402, a processing unit 403, and a playback unit 404. Wherein the obtaining unit 401 is configured to obtain the self aspect ratio of the target video from the video file of the target video. The comparing unit 402 is configured to determine whether the aspect ratio of the video playing information is consistent with that of the video playing information corresponding to the target video, and the video playing information is issued by the server. The playing unit 403 is configured to process the target video based on the aspect ratio of the video playing device and the aspect ratio of the screen of the video playing device, in response to determining that the aspect ratio of the video playing device is inconsistent with the aspect ratio of the video playing device, to obtain a processed video. The playback unit 404 is configured to play back the processed video.
In some embodiments, specific implementations of the obtaining unit 401, the comparing unit 402, the processing unit 403, and the playing unit 404 in the video playing apparatus 400 and the technical effects thereof may refer to step 201 and step 204 in the embodiment corresponding to fig. 2, which are not described herein again.
In an alternative implementation of some embodiments, the processing unit 403 may be further configured to: determining the type of the target video; and processing the target video based on the aspect ratio of the target video, the aspect ratio of the screen of the video playing device and the type of the target video.
In an optional implementation of some embodiments, the obtaining unit 401 may be further configured to: before the first preset number of frames of the target video are played, the self aspect ratio of the target video is obtained from the video file of the target video.
In an alternative implementation of some embodiments, the processing unit 403 may be further configured to: in response to the fact that the type of the target video is determined to be a horizontal version video, fixing the width of the target video, and cutting the height of the target video based on the self aspect ratio and the aspect ratio of the screen; and in response to the fact that the type of the target video is determined to be a portrait video, fixing the height of the target video, and cutting the width of the target video based on the aspect ratio of the target video and the aspect ratio of the screen.
In some embodiments, the aspect ratio delivered by the server is checked by comparing the aspect ratio of the video itself with the aspect ratio delivered by the server. Therefore, video compression or amplification caused by server issuing errors can be avoided. And for the condition that the aspect ratio of the video player is inconsistent with the aspect ratio issued by the server, playing the target video based on the aspect ratio of the video player so as to correct the wrong aspect ratio and realize the normal playing of the video.
