Referring to fig. 1, a schematic diagram of an implementation environment according to an embodiment of the present invention is shown, where the implementation environment may include a video playing client 110, a video server 120, and a content distribution network 130.
The video playing client 110 is configured with a client local proxy server 111, where the client local proxy server 111 may be a local http (hypertext Transfer Protocol) server created at the client, and may be packaged with the client or separated from the client. The client local proxy server 111 may communicate with the video playback client over a local data communication path 112. The video playing client 110 may be an application installed in a terminal with a video playing function, and the terminal may be, but is not limited to, a smart phone, a desktop computer, a tablet computer, a notebook computer, a digital assistant, a smart wearable device, and the like.
The video server 120 may be a server providing an online video playing service, which may be an independently operating server, or a server cluster composed of a plurality of servers.
The content distribution network 130 is a one-layer intelligent virtual network based on the existing internet, which is formed by placing node servers at various positions of the network, and the content distribution network can redirect the user's request to the service node closest to the user in real time according to the network traffic, the connection of each node, the load condition, the distance to the user, the response time and other comprehensive information. In the embodiment of the present invention, the content distribution network 130 may store video files, audio files, and the like required for the video playing client 110 to play videos.
Both the video server 120 and the content distribution network 130 may communicate with the video playback client 110 over a network, which may be a wired network or a wireless network.
Referring to fig. 2, a flow chart of a video generation method according to an embodiment of the present invention is shown, where the method can be applied to the client-side home agent server in fig. 1. It is noted that the present specification provides the method steps as described in the examples or flowcharts, but may include more or less steps based on routine or non-inventive labor. The order of steps recited in the embodiments is merely one manner of performing the steps in a multitude of orders and does not represent the only order of execution. In actual system or product execution, sequential execution or parallel execution (e.g., parallel processor or multi-threaded environment) may be possible according to the embodiments or methods shown in the figures. Specifically, as shown in fig. 2, the method may include:
s201, receiving first address information and second address information returned by a video server aiming at a playing request of a target video sent by the video playing client.
The first address information is the address information of an original video file matched with the target video, and the second address information is the address information of an add-on audio track file matched with the target video.
In this embodiment of the present description, when a user wants to watch a certain video in a video playing client, the user may click to play the target video, so that the video playing client sends a playing request of the target video to the video server in response to a click operation of the user. Correspondingly, the video server receives a playing request of the target video, and determines first address information of an original video file matched with the target video and second address information of a plug-in audio track file matched with the target video according to the playing request. In practical application, the video server may store the first address information and the second address information corresponding to the video identifier according to the video identifier, the play request may carry the video identifier of the target video, and the video server may find the first address information and the second address information by matching the video identifier. Wherein the video identification can be used for the video server to uniquely identify a specific video.
A plug-in soundtrack file refers to an audio data file that matches a target video but is independent of the corresponding original video file. The external audio track file matched with the target video can be an audio track file of a single audio track, and can also comprise audio track files of a plurality of different audio tracks, wherein audio data of a certain language (such as English, Chinese and the like) is recorded in the audio track file of each audio track.
In the embodiment of the specification, the client local proxy server receives first address information of an original video file returned by the video server and second address information of a plug-in audio track file.
It should be noted that, if the target video does not have the external audio track file, the video server may only search the first address information of the original video file matched with the target video, at this time, the video server may only return the first address information of the original video file, and correspondingly, the client-side local proxy server may receive the returned first address information of the original video file.
S203, acquiring the video data in the original video file according to the first address information.
In this embodiment of the present description, after receiving the first address information, the client-side local proxy server may send a first content acquisition request to the content distribution network, where the first content acquisition request carries the first address information, so that the content distribution network determines an original video file matched with the first address information, and sends the original video file to the client-side local proxy server; correspondingly, the client local proxy server receives the original video file returned by the content distribution network.
In practical applications, the video data and the audio data are both encapsulated in an original video file, and the original video file corresponds to a multimedia container having a certain video container format, which may include but is not limited to hls, avi, mp4, mkv, flv, rm/rmvb, mov, ts, vob, dat, etc. The video data and the audio data in the original video file can be in a compressed format or a non-compressed format, wherein the compressed format of the video data can be but is not limited to mpeg2, mpeg4, H264, VC1, Rm/Rmvb and the like; the compression format of the audio data may include, but is not limited to, MPA, AAC, AC3, DTS, and the like.
Therefore, in step S203, the client-side local proxy server further needs to decapsulate the original video file to separate the video data and the audio data therein, so that the individual video data therein can be obtained. Specifically, the original video file can be unpacked by using the multimedia video processing tool FFmpeg, which is a set of open source computer programs that can be used to record, convert digital audio and video, and convert them into streams, and includes the very advanced audio/video codec libavcodec, of course, the FFmpeg can also integrate other codec libraries, such as x264, fac, lamc, fdkaac, etc.
S205, acquiring the plug-in audio data in the plug-in audio track file according to the second address information.
In this embodiment of the present specification, after receiving the second address information, the client-side local proxy server may send a second content acquisition request to the content distribution network, where the second content acquisition request carries the second address information, so that the content distribution network determines a plug-in audio track file matched with the second address information, and sends the plug-in audio track file to the client-side local proxy server; correspondingly, the local proxy server of the client receives the plug-in audio track file returned by the content distribution network.
In practice, the external audio track file is also a packaged audio container format file, which may include, but is not limited to, MP3, WAV, AAC, APE, FLAC, and so on. The external audio data in the external audio track file can be in a compressed format or an uncompressed format, wherein the audio compressed format can include but is not limited to MPA, AAC, AC3, DTS, and the like. Therefore, in step S205, the client-side local proxy server further needs to decapsulate the external audio track file to obtain the external audio data, and specifically, the aforementioned multimedia video processing tool FFmpeg may also be used to decapsulate the external audio track file.
In some embodiments, the add-on soundtrack files returned by the content delivery network to the client-side local proxy server include soundtrack files corresponding to different soundtracks, for example, add-on english files, add-on chinese files, etc., in which case the client-side local proxy server may adopt the method of fig. 3 when unpacking the add-on soundtrack files to obtain the add-on audio data, as described in fig. 3, and the method may include:
s301, sending the audio track identifier of the audio track file to a video playing client, so that the video playing client displays the audio track identifier.
The audio track identifier may be a language name of the audio track, such as Chinese, English, etc., or may be a language code, such as chs (Chinese), eng (English), etc. The client local proxy server sends the audio track identification of each audio track file to the video playing client so that the video playing client can display the audio track identification, and therefore a user can select according to different requirements of the user on voice.
S303, determining a target audio track identity in response to a selection signal for said audio track identity.
In particular, when a user selects a certain track identity, e.g., clicks on a certain track identity, the client local proxy server may determine a target track identity in response to a selection signal for the track identity. For example, the user clicks on the chinese language, the client local proxy server determines the chinese language as the target track identification.
S305, de-encapsulating the target audio track file corresponding to the target audio track identifier to obtain target audio data, wherein the target audio data is used as the plug-in audio data.
Specifically, the client-side local proxy server only decapsulates the target audio track file corresponding to the target audio track identifier, such as Chinese, so as to obtain target audio data, and uses the target audio data as the obtained plug-in audio data.
It should be noted that, step S203 and step S205 may be executed separately as described above, or may be combined into one step and executed simultaneously, that is, the client-side local proxy server may send a content obtaining request to the content distribution network, where the content obtaining request includes the first address information and the second address information at the same time, the content distribution network determines the corresponding original video file and the corresponding external audio track file according to the first address information and the second address information, and returns the original video file and the external audio track file to the client-side local proxy server at the same time, and after receiving the original video file and the external audio track file, the client-side local proxy server decapsulates the original video file and the external audio track file, respectively, so as to obtain the corresponding video data and external audio data.
And S207, generating a target video file according to the video data and the plug-in audio data so that the video playing client can acquire and play the target video file.
Specifically, the video data and the plug-in audio data may be repackaged by using a multimedia video processing tool FFmpeg to obtain a target video file, and a video container format of the repackaged target video file may be the same as a video container format of the original video file, for example, MP4 or HLS, or may be different from the video container format of the original video file, for example, the target video file may be a preset video container format, and the preset video container format may be, but not limited to, HLS, avi, MP4, mkv, flv, rm/rmvb, mov, ts, vob, dat, and the like.
The client local proxy server can send the target video file to the video playing client after generating the target video file, and the video playing client can perform playing operation of the target video file after acquiring the target video file.
In practical application, before the client local proxy server generates the target video file, whether the sound effect level of the plug-in audio data is higher than that of the audio data in the original video file can be judged, and if the judgment result is yes, the step of generating the target video file according to the video data and the plug-in audio data is executed. Specifically, the sound effect level may include a normal sound effect, a dolby sound effect, and the like, so that it may be ensured that the regenerated target video file has a better sound effect experience. For example, when the sound effect level of the plug-in audio data is the dolby sound effect and the sound effect level of the audio data in the original video file is the common sound effect, the step of generating the target video file according to the video data and the plug-in audio data can be executed; and when the sound effect grade of the plug-in audio data and the sound effect grade of the audio data in the original video file are both common sound effects, the step of generating the target video file can not be executed.
In this example, a client-side local proxy server may provide a local proxy service and a package-transfer service, where the local proxy service may be used to interact with a video server and a content distribution network to obtain an original video file and a plug-in audio track file; the decapsulation service may be used to decapsulate original video files and add-on audio track files, as well as to repackage video data and add-on audio data.
As shown in fig. 4, the home agent service acquires an original video file in the HLS format, which includes video data in a compressed format (the compressed format is H264) and audio data (the compressed format is AAC), and acquires an add-on audio track file in the MP3 format, which includes add-on audio data in a compressed format of AC 3. In this example, the video data in the original video file may be enhanced Dolby vision (Dolby vision) or normal video, and the audio data therein is normal audio without enhancement; the external audio data in the external audio track file is enhanced Dolby audio (Dolby audio).
