[0053] In order to make the purposes, technical solutions and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present application.

[0054] It should be noted that the description of "first", "second" and the like in the embodiments of the present application is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the technical features indicated or the number of the technical features indicated. Therefore, the features with "first", "second" can explicitly or implicitly include at least one of the features. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can realize it, and when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, and is not within the scope of protection claimed by the present application.

[0055] In the description of the present application, it should be understood that the numerical reference number before the step does not indicate the order of execution of the steps before and after the step, but is only used to facilitate the description of the present application and to distinguish each step, and therefore cannot be understood as a limitation on the present application.

[0056] First, the terms related to the present application are explained:

[0057] Encapsulation format: generally called encapsulation format or container format, is a format used to store audio and video data.

[0058] MP4: MP4 or MPEG-4 Part 14 is a standard digital multimedia container format. The extension for MPEG-4 Part 14 is.mp4, which is mainly used to store digital audio and digital video, but can also store subtitles and still images. It is a streaming format as it can contain a video stream that supports bit streaming (such as advanced video coding). The format of MP4 stores various data in units of Box, which can contain another Box.

[0059] Track: Common media files contain audio and video, which are generally called audio track and video track respectively. Generally, a media file contains only one audio track and one video track, but many encapsulation formats support multiple tracks.

[0060] MediaSource: Media Source Extensions API or MSE is a media playback interface provided by the browser to developers, which allows playing audio and video files generated by program code, instead of only playing audio and video from files or network addresses.

[0061] Keyframe: A complete content frame that can be used as a starting frame. Non-key frames are frames that need to refer to one or more frames to synthesize complete content.

[0062] MIME Type: Multipurpose Internet Mail Extensions (MIME) is an Internet standard. Browsers usually use MIME types (not file extensions) to determine how to handle URLs, so it is very important for web servers to add the correct MIME type in the response header. If the configuration is not correct, the browser may not be able to parse the file content, the website will not work properly, and the downloaded file will also be processed incorrectly. In MediaSource, MIME Type is needed to tell the browser the format of the currently played audio and video.

[0063] Secondly, in order to facilitate the understanding of the technical solutions provided by the person skilled in the art, the related art is described as follows:

[0064] MP4 format container supports storing multiple audio and video tracks, and most local players support switching the currently played track at any time when playing multi-track media files.

[0065] In the web browser standard, track switching can be performed by controlling the enabled attribute of audioTracks and videoTracks, but this function is not supported in the new version and most browser kernels on the market.

[0066] In view of poor support of browsers for multi-track media formats, most solutions store tracks in multiple media files, so that each media file has only one audio or video track, and each time the video track file and the audio track file needed for playing are downloaded for playing, and then played through the MediaSource interface provided by the browser.

[0067] Although multi-track media is an industry standard, it is currently only used in local playback scenarios because only a small number of browsers support it. When playing multimedia video in a browser, although the media files of multiple tracks can be preprocessed into multiple media files on a server to achieve playback and track switching, there is a big difference between the preprocessing and playback logic and the ordinary media playback logic, which is reflected in that the previous media only needs to download one media file, but after using this solution, at least two media files need to be downloaded, thus increasing the use cost and making it difficult to reuse the existing server and client system.

[0068] To this end, an embodiment of the present application provides a technical solution for switching of media files. In the technical solution, track basic information corresponding to a multimedia file is obtained, wherein the multimedia file corresponds to multiple media files of different tracks, and the track basic information includes a flag bit, wherein the flag bit is used to indicate the main track currently needed for playing; in response to a switching event for the played media file, the flag bit in the track basic information is adjusted; and the media file played in the embedded player of the webpage is controlled according to the flag bit. By adding a flag bit field to the track basic information corresponding to the multimedia file, the flag bit field is used to indicate the main track currently needed for playing, and when the media file of the track currently played needs to be switched, the track to be switched to is directly set as the main track and the other tracks are set as non-main tracks by modifying the flag bit in the track basic information, so that the switching of the media file in the embedded player of the webpage can be realized through the flag bit, the switching process has small delay, and the media file can be switched without user awareness at the user end, so that the same seamless switching of audio or video tracks as the local player can be realized in the webpage / browser, without lag, black screen, or jump in playing time, and the use cost of the solution is low and the solution is easy to reuse in the existing server and client system. See the following for details.

[0081] Embodiment One

[0082] FIG. 2 shows a flow chart of a switching method of a media file according to Embodiment One of the present application.

[0083] As shown in FIG. 2, the switching method of the media file can include steps S202-S208, wherein:

[0084] In step S202, track basic information corresponding to a multimedia file is acquired; the multimedia file corresponds to media files of multiple different tracks, and the track basic information contains a flag bit, wherein the flag bit is used to indicate a main track currently required to be played.

[0085] In step S204, in response to a switching event of the played media file, the flag bit in the track basic information is adjusted.

[0086] In step S206, the media file played in the embedded player of the switching webpage is controlled according to the flag bit.

[0087] The switching method of the media file provided by the present embodiment: by adding a flag bit field in the track basic information corresponding to the multimedia file, the flag bit field is used to indicate the main track currently required to be played, when the media file of the track currently played needs to be switched, the track required to be switched is directly set as the main track and the other tracks are set as non-main tracks by modifying the flag bit in the track basic information, so that the switching of the media file in the embedded player of the webpage can be realized by the flag bit, the switching process can be realized without feeling by the user end, so that the seamless switching of the audio or video track in the webpage / browser can be realized as the local player, without appearing to be stuck, black screen, and time jump, and the use cost of the scheme is lower, and it is easy to be reused in the existing server and client system.

[0088] The steps S202-S206 and optional other steps are described in detail below in combination with FIG. 2.

[0089] In step S202, track basic information corresponding to a multimedia file is acquired; the multimedia file corresponds to media files of multiple different tracks, and the track basic information contains a flag bit, wherein the flag bit is used to indicate a main track currently required to be played.

[0090] The multimedia file corresponds to media files of multiple different tracks, such as two video tracks and two audio tracks, and these media files of different tracks can be packaged in one multimedia file, and the media file currently required to be played can be selected when played in the embedded player of the webpage.

[0091] In the embodiment, in order to realize seamless switching of the media file played in the embedded player of the webpage, a mark bit field is added in the track basic information corresponding to the multimedia file, and the mark bit field is used to indicate the main track currently required to be played, wherein the main track is the track used by the player by default, so that when the track needs to be switched, the mark bit field can be directly modified. Specifically, the embedded player of the webpage reads the main track indicated in the mark bit field and acquires the multimedia file corresponding to the main track to play the multimedia file each time the multimedia file is played.

[0092] Step S204, in response to the switching event of the played media file, adjusting the mark bit in the track basic information;

[0093] Specifically, a processing program for realizing switching of the media file is deployed in the embedded player of the webpage, and when the embedded player of the webpage receives the switching event of the played media file, the processing program can be used to respond to the switching event of the played media file to adjust the mark bit in the track basic information.

[0094] Step S206, according to the mark bit, controlling switching of the media file played in the embedded player of the webpage.

[0095] In the embodiment, the embedded player of the webpage reads the main track recorded in the mark bit field and acquires the multimedia file corresponding to the main track to play the multimedia file each time the multimedia file is played. Specifically, after the embedded player of the webpage completes the played media file, the mark bit in the track basic information is re-read, and then the key frame of the media file corresponding to the main track is acquired according to the mark bit, the key frame is sent to the MediaSource interface of the embedded player of the webpage, and the media file corresponding to the main track is played by using the MediaSource interface.

[0096] In an optional embodiment of the present application, the track basic information corresponding to the multimedia file is acquired, including:

[0097] The multimedia file is acquired, and the track basic information corresponding to the multimedia file is parsed from the multimedia file.

[0098] In the embodiment, a processing program for realizing switching of the media file is deployed in the embedded player of the webpage, and when the media file is played, the processing program can be used to acquire the multimedia file and parse the track basic information corresponding to the multimedia file from the multimedia file.

[0099] Specifically, different packaging formats have different storage structures for multi-track files, but most formats include a "track information area" and a "data area". For example, in the MP4 format shown in FIG. 3, each area is referred to as a Box, the track header is stored by means of a TKHD and a TFHD Box, MDAT is an audio / video data block, and the track and data can be associated by means of the TKHD and the TFHD Box. In addition, the MP4 format includes other types of Box, which are omitted in FIG. 3.

[0100] The TKHD includes a flag indicating whether the current track is a main track (the main track is a track that is used by default by a player), and if the TFHD exists, the TKHD associates the track number (track_id) with the TFHD having the same track number.

[0101] In most browsers, all formats in the track can be listed in the MIME Type and placed in the codecs field to enable the browser to normally play the video. For example, if a media file includes two AVC tracks and two AAC tracks, the media file can be written as video / mp4; codecs="avc1.64002a, avc1.64002a, mp4a.40.2, mp4a.40.2".

[0102] In an optional embodiment of the present application, after the step of obtaining the track header information corresponding to the media file, the method further includes:

[0103] storing the track header information corresponding to the media file in a preset cache area.

[0104] In this embodiment, the embedded player of the webpage can have a corresponding preset cache area, and after the track header information corresponding to the media file is obtained, the track header information corresponding to the media file can be stored in the preset cache area.

[0105] In an optional embodiment of the present application, the step of adjusting the flag in the track header information in response to a switching event for the played media file includes:

[0106] The step of adjusting the flag in the track header information in response to a switching event for the played media file includes:

[0107] In the embodiment, a processing program for realizing switching of media files is deployed in the embedded player of the webpage, and when the embedded player of the webpage receives a switching event for the played media file, the processing program is used to respond to the switching event for the played media file, and the flag bit in the track basic information cached in the preset cache area is adjusted, so as to realize switching of media files.

[0108] In an optional embodiment of the present application, the method for controlling switching of the media file played in the embedded player of the webpage according to the flag bit comprises:

[0109] In the case where the embedded player of the webpage completes the played media file, the flag bit in the track basic information cached in the preset cache area is read, and the media file played in the embedded player of the webpage is controlled according to the flag bit.

[0110] In the embodiment, in the case where the embedded player of the webpage completes the played media file, at this time, the embedded player of the webpage is ready to play the next media file, and the flag bit in the track basic information cached in the preset cache area is read. Since the flag bit in the track basic information cached in the preset cache area has been modified, the main track currently required to be played can be directly determined according to the modified flag bit, and the media file played in the embedded player of the webpage is controlled according to the flag bit.

[0111] It should be noted that if the flag bit is not modified, after the embedded player of the webpage reads the flag bit in the track basic information cached in the preset cache area, the multimedia file can be played according to the initially set main track.

[0112] In an optional embodiment of the present application, the method for controlling switching of the media file played in the embedded player of the webpage according to the flag bit comprises:

[0113] The target media file is determined from the plurality of different track media files according to the flag bit, and the media file played in the embedded player of the webpage is controlled to be switched to the target media file.

[0116] parsing the media files of the plurality of different tracks corresponding to the multimedia file from the data area of the multimedia file.

[0117] In the embodiment, the data structure of the multimedia file comprises a data area, and before determining the target media file, the media files of the plurality of different tracks corresponding to the multimedia file can be parsed from the data area of the multimedia file.

[0118] In an alternative embodiment of the present application, the step of adjusting the mark bit in the track basic information in response to the switching event for the played media file comprises:

[0119] In response to the switching event for the played media file, determining the first track currently required to be played and the second track currently not required to be played; wherein the second track comprises one or more media files; setting the first track as the main track and setting the second track as the non-main track in the mark bit.

[0120] In the embodiment, a processing program for implementing the switching of media files is deployed in the embedded player of the webpage, when the embedded player of the webpage receives the switching event for the played media file, the processing program determines the first track currently required to be played and the second track currently not required to be played in response to the switching event for the played media file; wherein the second track comprises one or more media files; then, the first track is set as the main track and the second track is set as the non-main track in the mark bit. For example, in FIG. 3, it is assumed that the video 2 and the audio 1 are switched to, then the video 2 and the audio 1 are set as the main track, and the video 1 and the audio 2 are set as the non-main track.

[0121] The processing program caches the header information of the MP4, specifically, in the MP4, it is called MOOV, which comprises TKHD, then the mark bit indicating whether it is the main track in the cached TKHD is modified, the track switched to is set as the main track, and the other tracks are set as the non-main track, when the embedded player of the webpage is ready to insert the next audio / video key frame, the modified MP4 header information is sent into the MediaSource again, and then the key frame and the subsequent content are sent, so that the track switching is completed.
