To facilitate understanding of the present disclosure, the present disclosure relates to technical terms in which:
the video comprises MetaData (MetaData) and audio and video frames, wherein the MetaData is used for describing parsing information of the audio and video frames in the video, such as information of frame width, frame height, total duration, encoding format and the like. Generally, when a video is stored, metadata is located at a start position of the video, and when the video is played, a player needs to acquire and analyze the metadata of the video first, and then can decode and/or render an audio/video frame in the video according to the analyzed information.
The video starting speed refers to the time length from the time when the video is clicked to the time when the video starts to be played, wherein the starting speed is higher as the time length is shorter, and the starting speed is lower as the time length is longer.
First, it should be noted that the servers in the embodiment of the present application may be separately configured or dispersedly configured, and when dispersedly configured, the servers may include a video management server and a video storage server, where the video management server is mainly used to push video resource description information of a video to a terminal, and the video storage server is mainly used to store the video and is used to respond to a video download request of the terminal to send audio and video frames in the video to the terminal.
Referring to fig. 1, fig. 1 is a schematic diagram of an architecture of a video playing system according to an exemplary embodiment, which includes a video management server, a terminal and a video storage server, where the terminal is, for example, a mobile phone, an iPad, a tablet computer, and the like, and a client and a player capable of playing video on demand are installed in the terminal.
In specific implementation, the video management server pushes video resource description information of each video to the client, where the video resource description information of each video includes both address resource description information, such as a uniform resource locator (a video playing address), required for downloading the video, and metadata required for playing the video.
Subsequently, when the client receives a playing request for any video in the video list, the client can inquire the video resource description information of the video to be played from the video resource description information of each video according to the video identifier of the video to be played carried in the playing request, and send the address resource description information of the video to be played to the player, the player determines the initial address of the audio/video frame in the video to be played in the video storage server according to the address resource description information of the video to be played, and then sends the initial address carried in the video downloading request to the video storage server, the video storage server sends the audio/video frame at the initial address to the player after receiving the video downloading request, and the player plays the audio/video frame according to the metadata of the video to be played, thus skipping the downloading of the metadata in the video to be played and directly downloading the audio/video frame in the video to be played, and audio and video frames in any video in the video list do not need to be loaded in advance, so that the playing speed of the video can be improved, and the flow of a user can be saved.
Specifically, referring to fig. 2, fig. 2 is an interactive flowchart illustrating a video playing method according to an exemplary embodiment, including the following steps.
S201: the client sends a request for acquiring the video resource description information to the video management server.
In specific implementation, an operation of opening the client, an operation of logging in the client, or an operation of refreshing the video list in the client may trigger the client to send a request for obtaining the video resource description information to the video management server.
S202: and the video management server issues video resource description information of at least two videos to the client.
Wherein the video resource description information of each video comprises the address resource description information of the video and the metadata of the video.
In practical application, if each video stored in the video storage server includes an audio/video frame in the video and metadata of the video, the address resource description information of each video sent to the client by the video management server includes a playing address of the video and an offset position of the audio/video frame in the video.
Considering that the video management server issues metadata of each video to the client, in order to save the storage space of the video storage server, in the embodiment of the present disclosure, each video stored in the video storage server may only include a video frame in the video and no longer include the metadata of the video, at this time, if the user requests a video at the client, a first byte of the video to be played returned by the video storage server is an audio/video frame in the video to be played, so that the address resource description information of each video issued to the client by the video management server may directly include an initial address of the audio/video frame in the video storage server.
In addition, the metadata of each video sent to the client by the video management server can be analyzed on the video management server side, or on the terminal side, and if the metadata is analyzed on the video management server side, the metadata in the video resource description information of each video can be analyzed by the video management server before sending the video resource description information of each video to the client.
S203: and the client stores the video resource description information of each video sent by the video management server.
S204: the client receives a playing request for any video in the video list and determines video resource description information of the video to be played.
In specific implementation, when the client receives a play request for any video in the video list, the video resource description information of the video to be played can be queried from the video resource description information of each video according to the video identifier of the video to be played carried in the play request.
S205: and the client sends the video resource description information of the played video to the player.
S206: and the player determines the initial address of the audio and video frame in the video to be played in the video storage server according to the address resource description information of the video to be played.
Optionally, if the address resource description information of the video to be played includes a playing address of the video to be played and an offset position of an audio/video frame in the video to be played, the player may offset the playing address according to the offset position, so as to obtain an initial address of the audio/video frame in the video to be played in the video storage server.
Optionally, if the address resource description information of the video to be played includes the start address of the audio/video frame in the video to be played in the video storage server, the player may directly obtain the start address of the audio/video frame in the video to be played in the video storage server from the address resource description information of the video to be played.
S207: and the player carries the starting address in a downloading request and sends the downloading request to the video storage server.
Namely, skipping the downloading of the metadata of the video to be played, and directly downloading the audio/video frames in the video to be played.
S208: and the video storage server returns the audio and video frames at the starting address to the player.
S209: and the player plays the received audio and video frames according to the metadata of the video to be played.
Optionally, when the metadata of each video in the video list is analyzed by the video management server, the metadata in the video resource description information of each video sent by the video management server is analyzed, and at this time, the player can directly play the received audio/video frame according to the metadata analysis information of the video to be played, so that the metadata analysis time of the video to be played is saved, and the play start speed of the video to be played can be further increased.
Optionally, when the metadata of each video in the video list is parsed by the player, the metadata in the video resource description information of each video sent by the video management server is not parsed, and at this time, the player parses the metadata of the video to be played first, and then plays the received audio/video frame according to the metadata parsing information of the video to be played.
Specifically, referring to fig. 3, fig. 3 is a flowchart illustrating a video playing method according to an exemplary embodiment, as shown in fig. 1, the method is applied to a terminal and includes the following steps.
