Abstract

Embodiments of the present invention provide a video positioning and playing method and device, the method comprising: determining the changed playing time according to the received change instruction for the playing time of the video; acquiring the TS to which the changed playing time belongs Fragmentation file; determine the PES packet carrying the I frame corresponding to the changed playback time in the TS fragmentation file; start playing from the I frame carried in the determined PES packet. In the embodiment of the present invention, the I frame corresponding to the changed playback time can be located, which is equivalent to positioning in units of I frames, which greatly improves the positioning accuracy, and can reduce video rollback or advance after the user changes the playback time. The probability of disconnection can make the user feel that the video image is still seamlessly connected after changing the playback time, thereby greatly improving the user experience.

Description

technical field [0001] The present invention relates to the technical field of video playing, in particular, the present invention relates to a video positioning and playing method and device. Background technique [0002] With the advancement of technology, terminal devices such as smart set-top boxes, smart TVs, smart phones, tablets, laptops or desktop computers are widely used. Users usually use these terminal devices to play streaming media videos on the network. [0003] The program server usually cuts the complete TS (Transport Stream, transport stream) video file into multiple TS fragment files according to the time according to the HTTP-based streaming media protocol, such as HLS (HTTP Live Streaming, hypertext transfer protocol real-time streaming) protocol . Moreover, the program server assigns a segment number to each TS segment file according to the order of cutting, and generates a file identifier of the TS segment file according to the segment number. After...
