Detailed Description
The following description of the exemplary embodiments of the present application, taken in conjunction with the accompanying drawings, includes various details of the embodiments of the application to assist in understanding, which are to be considered exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Fig. 1 is a schematic flowchart of a conventional video online playing method. As shown in fig. 1, in an existing video online playing process, in order to solve the limitations of various video formats in the video playing process, such as too long loading time and pause in the playing process, most video applications adopt an HLS (HTTP Live Streaming, dynamic bitrate adaptive technology) video online playing method. The HLS is a streaming media network Transport Protocol based on HTTP (Hyper Text Transfer Protocol), and may convert a video file into a TS (Transport Stream) format, and fragment the TS to obtain a media fragment file, that is, a TS fragment file. Further, the HLS may organize the TS slice files by means of M3U8 (M3U file in UTF-8 encoding format) index files. When the client requests the server for the video data, a Uniform Resource Locator (URL) corresponding to the TS fragment file may be obtained by obtaining the M3U8 file from the server, so that the data is pulled from the server according to the URL of the TS fragment file and is parsed and played. The operation of rapidly searching the TS media fragment file can be realized by adopting a TS fragment mode, so that the whole video stream is divided into a plurality of small HTTP-based files for downloading, and only one section of video data is downloaded for playing each time.
Fig. 2 is a schematic structural diagram of a conventional TS fragmentation file. As shown in fig. 2, a TS slice file may have a plurality of packets (i.e., data information), and each Packet may include a header information and a data information. That is, a large amount of header information may be included in one TS slice file. Meanwhile, since the packet size in the TS slice file is fixed, redundant information may exist when video clip data is allocated. Therefore, due to the structure of the TS fragment file, data redundancy, including header information redundancy and video data redundancy, exists in the fragment file, which causes bandwidth waste in the process of playing a video on line at a client.
In an example, fig. 3 is a flowchart of a video online playing method provided in an embodiment of the present application, where this embodiment is applicable to a case where a video client implements online playing of a video by using a single-header video fragment file that includes only one piece of header information, and the method may be executed by a video online playing apparatus, which may be implemented by software and/or hardware, and may be generally integrated in an electronic device. The electronic device may be a video client device for use with a video server device. Accordingly, as shown in fig. 3, the method includes the following operations:
s110, acquiring a single-head video fragment file stored by a video server; wherein the single-header video slice file includes one header information.
The video server can store video file information in a fragment form, so that when the video client requests video data played online, the video server sends the video data in the fragment form to the video client. The single-header video slice file may be a video slice file including only one header information. A video slice file may be understood as a file formed by part of the video data in a complete video file.
In the embodiment of the application, after the video client sends the request of the video data to the video server, the single-header video fragment file corresponding to the requested video can be acquired from the video server, so that online video playing is performed according to the acquired single-header video fragment file. Fig. 4 is a schematic structural diagram of a single-header video slice file according to an embodiment of the present application. As shown in fig. 4, the single-header video slice file only includes one header information, and the data information in the single-header video slice file may be one or multiple, and may be specifically set according to an actual requirement and a slice requirement of the video file.
Therefore, the single-header video fragment file only comprises one header information, so that the problem of data redundancy of the header information caused by a plurality of header information can be effectively solved. It should be noted that the data content of the header information included in the single-header video slice file may be the same as the data content of the header information included in the TS slice file. Meanwhile, the data information of the single-head video fragment file can be flexibly set, so that the problem of video fragment data redundancy caused by the fixed size of the data information is avoided. Therefore, the embodiment of the application can greatly reduce the bandwidth cost of video online playing by adopting the single-head video slicing file to transmit and play the video data online. Experimental data show that the mode of performing video online playing by adopting the single-head video fragment file can save 10% of bandwidth cost compared with the mode of performing video online playing by adopting the TS fragment file.
In an alternative embodiment of the present application, the file format of the single-header VIDEO slice file may be MP4 (MPEG-4 part 14, a multimedia computer archive format using MPEG-4) format or FLV (FLASH VIDEO, streaming media format) format, and the embodiment of the present application does not limit the specific type of the file format of the single-header VIDEO slice file.
And S120, analyzing the single-head video fragment file to obtain video analysis data.
The video analysis data may be analysis data obtained by analyzing a single-header video fragment file by a video client, and may be used to realize online video playing. It should be noted that, in the embodiment of the present application, the video played online may include audio and/or video. That is, the video played online may include both audio data and video data, or only audio data or only video data. When the video played online only includes audio data, it may be understood that the video picture played online is empty, for example, the video picture is black, other preset colors or images.
Correspondingly, after the video client acquires the single-head video fragment file, the single-head video fragment file can be analyzed on line in real time to obtain video analysis data.
S130, the single-head video slicing file is played on line according to the video analysis data.
In the embodiment of the application, after the video client obtains the video analysis data online, the single-header video fragment file can be played online according to the video analysis data. That is, each single-header video slice file can be played individually at the video client. When the video client plays the nth fragment file, the (n + 1) th fragment file can be preloaded, but the (n + 2) th fragment file can not be loaded, so that the single-head video fragment file can be loaded and played section by section, and the problem that the bandwidth is seriously occupied because the whole video file is loaded from the beginning when the video client plays the video online is avoided. After a plurality of single-head video fragment files formed by fragments corresponding to one complete video are sequentially played, the whole video is played on line.
Therefore, the method and the device for playing the video on line by adopting the single-head video fragment file can reduce the problem of bandwidth waste caused by the problem of data redundancy, thereby reducing the bandwidth cost of video on line playing. Meanwhile, the data redundancy problem of the single-head video fragment file is reduced, and the storage resources occupied by the single-head video fragment file in the video server can be reduced, so that the storage cost of the video file in the video server is reduced.
According to the embodiment of the application, the single-head video fragment file stored by the video server is obtained through the video client, so that the single-head video fragment file is analyzed to obtain video analysis data, and the single-head video fragment file is played on line according to the video analysis data. Because the single-head video fragment file comprises the head information, the redundant storage and transmission of the video data are avoided, and the problems of the redundant storage of the video data and the waste of bandwidth resources in the existing video online playing method are solved, so that the storage cost of the video file in a video server is reduced, and the bandwidth cost of the online playing of the video is reduced.
In an example, fig. 5 is a flowchart of a video online playing method provided in an embodiment of the present application, and fig. 6 is a flowchart of a video online playing method provided in an embodiment of the present application, and the embodiment of the present application performs optimization and improvement on the basis of the technical solutions of the above embodiments, and provides various specific optional implementation manners of acquiring a single-header video fragment file stored by a video server, parsing the single-header video fragment file, and playing the single-header video fragment file online according to the video parsing data.
As shown in fig. 5 and fig. 6, a method for playing a video online includes:
s210, acquiring a fragment improved M3U8 file from the video server; and generating the fragment improved M3U8 file according to the single-header video fragment file.
The fragmentation improved M3U8 file may be an M3U8 index file generated according to the single-header video fragment file, and may be used to organize the single-header video fragment file.
In this embodiment of the present application, the video server may organize a single-header video fragment file formed by a complete video in a manner of a fragment-modified M3U8 file. Therefore, the video client may first obtain the sharded improved M3U8 file corresponding to the requested video from the video server before obtaining the single-header video sharded file.
S220, analyzing the fragment improved M3U8 file to obtain the single-head video fragment file.
Correspondingly, the video client can analyze the acquired fragment improved M3U8 file to acquire the URL corresponding to each single-head video fragment file, so as to sequentially download each single-head video fragment file from the video server according to the URL acquired by analysis.
It should be noted that, in the embodiment of the present application, the file composition structure of the slice improvement M3U8 is the same as that of the existing HLS M3U8, and the difference is only that the format type of the video slice file is different. Namely: the conventional HLS M3U8 structure organizes video resources in a TS (transport stream) fragment file mode, and the fragment improved M3U8 structure organizes video resources in a single-header video fragment file mode.
According to the technical scheme, the video client can acquire the single-head video fragment file corresponding to the video resource by acquiring and analyzing the fragment improved M3U8 file, and then the video is played on line in a single-head video fragment file mode, so that the bandwidth cost of video online playing is reduced.
And S230, analyzing the header information of the single-header video slicing file to obtain header information analysis data.
The header information analysis data may be data obtained by analyzing header information of a single-header video slice file.
Optionally, the video client may first analyze the header information of the single-header video fragment file to obtain header information analysis data, so as to further analyze the data information of the single-header video fragment file according to the header information analysis data.
In an optional embodiment of the present application, the parsing the header information of the single-header video slice file may include: analyzing meta information in the head information to obtain head information analysis data; the head information analysis data comprises a fragment video playing position and video decoding data.
The fragment video playing position can be used for determining the playing position of the single-head video fragment file relative to the whole complete video. Illustratively, when the clip video playing position is "10s-20s", it indicates that the single-header video clip file can play the video clip between 10s and 20s of the whole video. The video decoding data may be used to decode data information in a single-header video slice file.
Specifically, the video client may analyze meta information in the header information to obtain header information analysis data such as a slice video playing position and video decoding data corresponding to the single-header video slice file. Alternatively, the Meta information may be Meta information or the like.
The playing position of the sliced video and the video decoding data are obtained by analyzing the meta-information in the header information, so that the subsequent data decoding operation and the rendering operation of the video data can be assisted.
S240, analyzing the data information of the single-head video fragment file according to the head information analysis data to obtain the video analysis data.
Wherein the video parsing data may comprise parsing audio data and/or parsing video data. The parsed audio data may be audio data parsed from the single-header video fragment file, and the parsed video data may be video data parsed from the single-header video fragment file.
Correspondingly, after the video client analyzes the header information of the single-header video fragment file to obtain the header information analysis data, the data information can be further analyzed by using the header information analysis data to obtain the analysis audio data and/or the analysis video data which can be played on line by the video client.
In an optional embodiment of the present application, the parsing the data information of the single-header video slice file according to the header information parsing data may include: decapsulating the single-header video fragment file to obtain compressed audio data and/or compressed video data; determining a target audio decoder and/or a target video decoder according to the video decoding data; decoding the compressed audio data according to the target audio decoder to obtain the analysis audio data; and/or decoding the compressed video data according to the target video decoder to obtain the analysis video data.
The compressed audio data may be compressed audio data in a single-header video slice file, that is, audio data before decoding. The compressed video data may be compressed video data in a single-header video slice file, that is, video data before decoding. The target audio decoder may be a type of decoder adapted to the data format of the compressed audio data for decoding the compressed audio data. The target video decoder may be of a type adapted to the data format of the compressed video data for decoding the compressed video data.
The single-head video fragment file acquired by the video client is data obtained by encapsulating compressed audio data and/or compressed video data. Therefore, when the video client parses the data information of the single-header video slicing file, it needs to decapsulate the single-header video slicing file to obtain compressed audio data and/or compressed video data. Correspondingly, if the compressed audio data exists, the video client can determine the audio format of the compressed audio data according to the video decoding data to determine an adaptive target audio decoder, and decode the compressed audio data according to the target audio decoder, so as to obtain corresponding analysis audio data. If the compressed video data exists, the video client can determine the video format of the compressed video data according to the video decoding data to determine an adaptive target video decoder, and decode the compressed video data according to the target video decoder to obtain corresponding analysis video data. Alternatively, the audio format for parsing the audio data may be, for example, a format of audio sample data, such as a PCM (Pulse-code-modulation) format. The video format for parsing the video data may be, for example, YVU (a color coding method) format or the like. The embodiment of the present application does not limit the specific data format types for parsing the audio data and parsing the video data.
According to the technical scheme, the target audio decoder and/or the target video decoder are determined according to the video decoding data, so that the compressed audio data and/or the compressed video data can be quickly decoded, and the analysis efficiency of the data information is improved.
And S250, acquiring a fragment video playing position corresponding to the video analysis data.
Correspondingly, after the video client obtains the video parsing data, the video client can obtain the fragment video playing position of the single-header video fragment file from the header information parsing data, and the fragment video playing position can be used for determining the playing time period position of the video parsing data in the video client.
S260, performing online rendering on the video analysis data according to the fragment video playing position so as to realize online playing of the video analysis data.
After the video client determines the playing time interval position of the video analytic data in the video client, the video analytic data can be rendered on line according to the determined fragment video playing position, so that real-time online playing of the video analytic data is realized. After the real-time online playing of the plurality of video analysis data obtained by analyzing the plurality of single-head video fragment files corresponding to the complete video file is respectively completed according to the fragment video playing positions, the online playing of the complete video file is completed.
Fig. 7 is a schematic flowchart of an existing online video playing method provided by an embodiment of the present application, and as shown in fig. 6 and 7, the online video playing method provided by the embodiment of the present application is substantially similar to the entire flow of the existing online video playing method, except that the type of the M3U8 file and the type of the video slice file are different. Meanwhile, when the existing video online playing method is used for analyzing the TS fragment file, the data information of the TS fragment file can be directly analyzed.
According to the technical scheme, the video slicing file only comprises one piece of header information by changing the file structure of the video slicing file, so that the redundancy of the header information of the video slicing file is greatly reduced. Meanwhile, the flexible setting of the data information of the video fragment file can effectively reduce the redundancy of the video data, not only can reduce the storage cost of the video file in a video server, but also can reduce the bandwidth cost of the online playing of the video.
In an example, fig. 8 is a flowchart of a video online playing method provided in an embodiment of the present application, where the present embodiment is applicable to a case where a video server stores video data according to a single-header video slice file that includes only one header information, and the method may be performed by a video online playing apparatus, which may be implemented by software and/or hardware, and may be generally integrated in an electronic device. The electronic device may be a video server device for use with a video client device. Accordingly, as shown in fig. 8, the method includes the following operations:
and S310, acquiring an original video file.
The original video file may be a video file required to be stored in a video server, and may be a complete video file. The format of the original video file may be any one of mkv format, rmvb format, mp4 format, avi format, flv format, and wmv format, and the file format of the original video file is not limited in this embodiment of the application.
In the embodiment of the present application, the video server may obtain the original video file in a variety of optional ways. The type of the video server may be a cloud storage server or the like.
S320, carrying out video slicing processing on the original video file to obtain a single-head video slicing file; wherein the single-header video slice file includes one header information.
Correspondingly, after the video server acquires the original video file, a fragmentation command can be called to perform fragmentation processing on the original video file to obtain a plurality of single-header video fragmentation files. The method comprises the steps of carrying out fragmentation processing on an original video file, dividing a larger video file into a plurality of relatively smaller fragment files, so that when a video client plays an nth fragment file, an n +1 th fragment file can be preloaded, but the n +2 th fragment file cannot be loaded, and loading and playing a single-head video fragment file section by section are realized, thereby avoiding the problem that the bandwidth is seriously occupied because the whole video file is loaded from the beginning when the video client plays a video on line, effectively reducing the waste of the bandwidth and hardware resources of a video server, relieving the pressure of the video server, ensuring that the video playing is smoother, and bringing better experience to users.
And S330, storing the single-head video fragment file.
After the video server performs fragmentation processing on the original video file to obtain a plurality of single-header video fragment files, each single-header video fragment file can be locally stored.
In an optional embodiment of the present application, the storing the single-header video slice file may include: generating a fragment improved M3U8 file according to the single-header video fragment file; storing the slice-modified M3U8 file and the single-header video slice file.
Optionally, the video server may generate a fragment improved M3U8 file according to each obtained single-header video fragment file, and perform index management on each fragment improved M3U8 file. Accordingly, the video server may store the slice-modified M3U8 file and the single-header video slice file simultaneously.
Optionally, the file format of the single-header video slice file is MP4 format or FLV format.
According to the technical scheme, the video resources are organized in the mode of the single-head video fragment file by adopting the fragment improved M3U8 file, and the video client can realize the online video playing in the mode of the single-head video fragment file, so that the storage cost of the video file in the video server is reduced, and the bandwidth cost of the online video playing is reduced.
According to the embodiment of the application, the single-head video fragment file of the original video file is stored in the video server, so that the redundant storage of video data can be avoided, and the problem of redundant storage of video data in the existing video online playing method is solved, so that the storage cost of the video file in the video server is reduced, and the bandwidth cost of online video playing is further reduced.
In an example, fig. 9 is a structural diagram of a video online playing apparatus provided in an embodiment of the present application, where the embodiment of the present application is applicable to a case where a video client implements online playing of a video by using a single-header video fragment file that only includes one piece of header information, and the apparatus is implemented by software and/or hardware and is specifically configured in an electronic device. The electronic device may be a video client device for use with a video server device.
