Abstract

Embodiments of the disclosure provide a live-streaming starting method, apparatus, device, storage medium, program product and program. The server receives a live-streaming starting request initiated by a terminal for streaming media; determines a starting segment according to a predetermined delay threshold, the starting segment comprising a media presentation description MPD file, an initialization segment, and a media segment corresponding to the delay threshold; and the terminal receives the starting segment sent by the server, and renders and plays a first frame of the streaming media using the starting segment. On the basis of a DASH protocol, the solution improves a live-streaming starting process, to enable a terminal to render and play a first frame only by initiating a starting request once, thereby effectively reducing a starting time and improving the user experience.

First claim

What is claimed is:

1 . A live-streaming starting method, applied to a server;
the method comprising: receiving a live-streaming starting request initiated by a terminal for streaming media; determining a starting segment according to a predetermined delay threshold, the starting segment comprising a media presentation description MPD file, an initialization segment, and a media segment corresponding to the delay threshold; and sending the starting segment to the terminal, the starting segment being used for rendering the first frame of live-streaming in response to the terminal starting live-streaming.

2 . The method of claim 1 , wherein the starting segment further comprises a segment serial number of the media segment and a start time of the media segment;
wherein the segment serial number of the media segment and the start time of the media segment are used to generate an obtaining request of the terminal for a next frame.

3 . The method of claim 1 , wherein the determining a starting segment according to a predetermined delay threshold comprises:
segmenting the streaming media according to a timestamp of each frame in the streaming media to obtain a plurality of continuous media segments with a same segment duration; selecting a target media segment corresponding to the delay threshold according to a predetermined delay threshold; and generating the starting segment according to the MPD file, the initialization segment, and the target media segment.

4 . The method of claim 3 , wherein the selecting a target media segment corresponding to the delay threshold according to a predetermined delay threshold comprises:
selecting, according to a start time of each media segment, a media segment with a latest start time from all unselected media segments as a to-be-processed media segment; determining whether a time difference between the start time of the to-be-processed media segment and a timestamp of a latest frame in the streaming media is greater than the delay threshold; in response to the time difference being greater than the delay threshold, taking the to-be-processed media segment as the target media segment; or in response to the time difference not being greater than the delay threshold, returning to the step of selecting, according to the start time of each media segment, a media segment with a latest start time from all unselected media segments as a to-be-processed media segment.

5 . The method of claim 4 , wherein in response to there being no media segment with a time difference between a start time and the timestamp of the latest frame in the streaming media greater than the delay threshold in each media segment, the method further comprises:
taking a media segment with an earliest start time in each media segment as the target media segment.

6 . The method of claim 1 , further comprising:
segmenting the streaming media according to a timestamp of each frame in the streaming media to obtain a plurality of continuous media segments with a same segment duration; generating a plurality of starting segments according to each media segment, wherein different starting segments comprise the MPD file, the initialization segment and different media segments; selecting a target starting segment from each starting segment according to a predetermined delay threshold; the determining a starting segment according to a predetermined delay threshold comprises: taking the target starting segment as the staring segment sent to the terminal.

7 . The method of claim 6 , wherein the selecting a target starting segment from each starting segment according to a predetermined delay threshold comprises:
selecting a target media segment corresponding to the delay threshold according to a predetermined delay threshold; and taking the staring segment corresponding to the target media segment as the target starting segment.

8 . The method of claim 7 , further comprising:
updating the target starting segment according to the timestamp of the latest frame of the streaming media.

9 . The method of claim 1 , wherein the starting segment comprises an MP4 format file.

10 . A live-streaming starting method, applied to a terminal;
the method comprising: sending a live-streaming starting request of a streaming media to a server; receiving a starting segment returned by the server, the starting segment being determined by the server according to a predetermined delay threshold; the starting segment comprising a media presentation description MPD file, an initialization segment, and a media segment corresponding to the delay threshold; and rendering and playing a first frame of the streaming media using the starting segment.

11 . The method of claim 10 , wherein the starting segment comprise an MP4 format file.

12 . The method of claim 10 , wherein the starting segment further comprises a segment serial number of the media segment and a start time of the media segment;
the method further comprises: generating an obtaining request for a next frame of the streaming media according to the segment serial number of the media segment and the start time of the media segment; and sending the obtaining request for the next frame to the server.

13 . An electronic device, comprising:
at least one processor, and a memory; the memory storing a computer executable instruction; the at least one processor executing the computer executable instruction stored in the memory, causing the at least one processor to implement acts comprising: receiving a live-streaming starting request initiated by a terminal for streaming media; determining a starting segment according to a predetermined delay threshold, the starting segment comprising a media presentation description MPD file, an initialization segment, and a media segment corresponding to the delay threshold; and sending the starting segment to the terminal, the starting segment being used for rendering the first frame of live-streaming in response to the terminal starting live-streaming.

14 . The electronic device of claim 13 , wherein the starting segment further comprises a segment serial number of the media segment and a start time of the media segment;
wherein the segment serial number of the media segment and the start time of the media segment are used to generate an obtaining request of the terminal for a next frame.

15 . The electronic device of claim 13 , wherein the determining a starting segment according to a predetermined delay threshold comprises:
segmenting the streaming media according to a timestamp of each frame in the streaming media to obtain a plurality of continuous media segments with a same segment duration; selecting a target media segment corresponding to the delay threshold according to a predetermined delay threshold; and generating the starting segment according to the MPD file, the initialization segment, and the target media segment.

16 . The electronic device of claim 15 , wherein the selecting a target media segment corresponding to the delay threshold according to a predetermined delay threshold comprises:
selecting, according to a start time of each media segment, a media segment with a latest start time from all unselected media segments as a to-be-processed media segment; determining whether a time difference between the start time of the to-be-processed media segment and a timestamp of a latest frame in the streaming media is greater than the delay threshold; in response to the time difference being greater than the delay threshold, taking the to-be-process
