When the electronic device is software, it may be a plurality of software modules or a single software module, and the embodiment of the application is not limited.

Specifically, in the video playing stage, the user triggers a player in the terminal device to send a playing request to the server, and the server returns a video file to the player for the player to play the video file. In the process of playing the video file, a user has annotation demands on the currently played video content, the player responds to the annotation operation of the user, obtains annotation information added by the user for the currently played video content, determines a time stamp of the currently played video content, sends the time stamp of the currently played video content and the annotation information thereof to a server, and the server stores the time stamp of the currently played video content and the annotation information thereof in the annotation file in an associated mode.

It should be noted that, the application scenario shown in fig. 1 is only an exemplary application scenario, and the embodiment of the present application is not limited to the application scenario. The embodiment of the present application does not limit the devices included in fig. 1, nor does it limit the positional relationship between the devices in fig. 1.

The following describes in detail the technical solutions provided by the embodiments of the present application with reference to the accompanying drawings.

Fig. 2 is a flowchart of a video playback method according to an embodiment of the present application. The method may be performed by a server, see fig. 2, and may comprise the steps of:

201. And receiving a video playback request sent by the terminal equipment, wherein the video playback request is used for indicating a video file of a playback target video name from a first time stamp.

202. In response to a video playback request, a target video file of video content corresponding to each second timestamp from the first timestamp is determined from among a plurality of video files of the stored target video name, the second timestamp being the first timestamp or other timestamp subsequent to the first timestamp, the target video file being one of the plurality of video files of the target video name.

Specifically, the server stores video files corresponding to one or more video names. In practical applications, there may be one or more video files corresponding to a video name. The server stores annotation files corresponding to one or more video names, and the annotation files store annotation information corresponding to video content with any time stamp in the video files corresponding to the video names. Further optionally, any timestamp and its corresponding annotation information association is stored in the annotation file.

The user may play back a video file of any video title, and herein, a video title corresponding to the video playback currently performed by the user is referred to as a target video title. And the terminal equipment of the user responds to the video playback operation triggered by the user and sends a video playback request to the server. The video playback request is used to indicate a video text for which playback of the target video title is started from a first timestamp, which can be understood as the timestamp at which playback is started, i.e. the playback start timestamp.

The server, in response to a video playback request, needs to determine the video file in which the video content of the time stamp of the desired playback is located in order to be ready for video playback. It will be appreciated that each time stamp from the first time stamp has an opportunity to play back until a user's play back end request sent by the terminal device is received to end video playback.

203. And sequentially taking one of the plurality of second time stamps as a current second time stamp according to the sequence of the second time stamps, acquiring video content corresponding to the current second time stamp from a target video file comprising video content corresponding to the current second time stamp, and inquiring annotation information corresponding to the current second time stamp from an annotation information file of the target video name.

204. And packaging the video content corresponding to the current second timestamp into first media stream data in a streaming media format, and packaging the annotation information corresponding to the current second timestamp into second media stream data in the streaming media format under the condition that the annotation information corresponding to the current second timestamp is queried.

Specifically, video content corresponding to each second time stamp is obtained in sequence, and the video content corresponding to the current second time stamp is packaged into first media stream data in a streaming media format. Streaming media formats include, for example, but are not limited to: FLV (Flash Video) streaming media format.

In practical application, a user annotates video content corresponding to each timestamp as required, so that annotation information corresponding to the current second timestamp may be queried from an annotation information file of the target video name, or annotation information corresponding to the current second timestamp may not be queried. And under the condition that the annotation information corresponding to the current second timestamp is queried, packaging the annotation information corresponding to the current second timestamp into second media stream data in a streaming media format. And under the condition that annotation information corresponding to the current second timestamp is not queried, the server only returns the first media stream data to the terminal equipment.

It is noted that the streaming format of the video content encapsulating the time stamp and the streaming format of the annotation information encapsulating the time stamp are of the same type, e.g. both FLV streaming formats.

In this embodiment, the video content corresponding to the current second timestamp may be encapsulated according to a conventional streaming media format, so as to obtain the first media stream data in the streaming media format, which is not limited.

Alternatively, to improve video playback efficiency, the user may customize the streaming media format, for example, the FLV streaming media format. Thus, the annotation information corresponding to the current second timestamp is packaged according to the self-defined FLV streaming media format. Based on this, encapsulating the annotation information corresponding to the current second timestamp into second media stream data in the streaming media format includes: and encapsulating annotation information corresponding to the current second timestamp by adopting an appointed data encapsulation format to obtain a first data packet, wherein the appointed data encapsulation format comprises the following steps: the first data packet comprises a current second timestamp, the length of annotation information corresponding to the current second timestamp and the annotation information corresponding to the current second timestamp; the streaming media format comprises a file header, a packet size field and a message body, wherein the annotation type is written in the file header, the size of the first data packet is written in the packet size field, and the first data packet is written in the message body, so that second media streaming data packaged into the streaming media format is obtained.

Specifically, the first packet is a packet encapsulated with annotation information. If the annotation information corresponding to the current second timestamp is only 1, the number of the first data packets is 1. If the number of the annotation information corresponding to the current second timestamp is multiple, each annotation information encapsulates one first data packet, and at this time, the number of the first data packets is multiple.

In this embodiment, the annotation type is written in the header of the streaming format, for example, if the header is written with 0xee, the 0xee indicates the annotation type. The size of the data packet written in the packet size field is used for checking the integrity of the data packet written in the message body, namely, whether the data packet is lost or not. The message body in streaming format is used for writing data packets.

If the annotation information corresponding to the current second timestamp is only 1, the number of the first data packets is 1, the size of the first data packets is written in the packet size field of the streaming media format, and the first data packets are written in the message body of the streaming media format. If the number of the first data packets is multiple, splicing the first data packets to obtain spliced first data packets, and correspondingly, writing the size of the spliced first data packets in a packet size field of a streaming media format and writing the spliced first data packets in a message body.

Further optionally, in order to improve transmission security of annotation information, the server may encrypt the first data packet to obtain an encrypted first data packet; correspondingly, writing the first data packet in the message body includes: writing the encrypted first data packet in the message body.

Of course, if the annotation information corresponding to the current second timestamp is multiple, the server side can encrypt the spliced first data packet to obtain the encrypted spliced first data packet; correspondingly, writing the first data packet in the message body includes: writing the encrypted spliced first data packet in the message body.

205. The method comprises the steps of sending first media stream data and second media stream data to a terminal device, enabling the terminal device to analyze the first media stream data to obtain video content corresponding to a current second time stamp, analyzing the second media stream data to obtain annotation information corresponding to the current second time stamp, rendering the video content corresponding to the current second time stamp in a playing interface, and displaying the annotation information corresponding to the current second time stamp at a corresponding position of a playing progress bar displayed on the playing interface.

According to the technical scheme provided by the embodiment of the application, in the video playback stage, the server takes a single timestamp as granularity, sequentially packages video content and annotation information of each timestamp to be played back into media stream data in the same type of streaming media format, and transmits the media stream data carrying the video content and the media stream data carrying the annotation information of each timestamp to the terminal equipment of a user, and the terminal equipment of the user can analyze according to the analysis method of the streaming media format of the same type to obtain the video content and the annotation information of the timestamp to be played back, and displays the video content and the annotation information of the timestamp to be played back so as to realize video playback. Therefore, video playback efficiency of the video file with annotation information is greatly improved, in addition, the annotation information of the timestamp is displayed on the corresponding position of the playing progress bar of the playing interface, so that a user can intuitively know the annotation information, and user experience is improved.

Wherein the third timestamp is an arbitrary timestamp.

302. And receiving the first media stream data and the second media stream data returned by the server in response to the video playback request.

Optionally, for secure transmission of annotation information, a streaming media format of the second media stream data includes a file header, a packet size field, and a message body, and correspondingly, parsing the second media stream data to obtain annotation information corresponding to the current second timestamp includes: if the second media stream data is obtained as the annotation type by analyzing the file header, analyzing the packet size field to obtain the size of the first data packet and analyzing the message body to obtain the first data packet; judging whether the size of the first data packet obtained by analyzing the packet size field is the same as the size of the first data packet obtained from the message body; if the first data packet is the same, the first data packet is unpacked to acquire the current second timestamp, the length of annotation information corresponding to the current second timestamp and the annotation information corresponding to the current second timestamp; calculating the length of annotation information corresponding to the current second timestamp, and judging whether the calculated length of annotation information corresponding to the current second timestamp is the same as the length of annotation information corresponding to the current second timestamp obtained by decapsulation; if the current second timestamp is the same, the annotation information corresponding to the current second timestamp obtained by decapsulation is determined to be valid. If the current second timestamp is different, the annotation information corresponding to the current second timestamp obtained by decapsulation is discarded.

It may be understood that if the annotation information corresponding to the current second timestamp is a plurality of pieces, the first spliced data packet is obtained by parsing the message body, and the size of the first spliced data packet is obtained by parsing the packet size field, at this time, the second media stream data is parsed to obtain the annotation information corresponding to the current second timestamp, which includes: if the second media stream data is obtained as the annotation type by analyzing the file header, analyzing the packet size field to obtain the size of the spliced first data packet and analyzing the message body to obtain the spliced first data packet; judging whether the size of the spliced first data packet obtained by analyzing the packet size field is the same as the size of the spliced first data packet obtained from the message body; if the first data packet is the same, the spliced first data packet is unpacked to acquire the current second timestamp, the lengths of a plurality of annotation information corresponding to the current second timestamp and a plurality of annotation information corresponding to the current second timestamp; calculating the lengths of a plurality of annotation information corresponding to the current second timestamp, and judging whether the lengths of the plurality of annotation information corresponding to the calculated current second timestamp are the same as the lengths of the plurality of annotation information corresponding to the unpackaged current second timestamp; if the first time stamp and the second time stamp are the same, determining that the plurality of annotation information corresponding to the current second time stamp obtained by decapsulation has validity.
