Abstract

The invention relates to a media data processing method and device and a media data playing method and device. The media data processing method comprises the steps of receiving a media data request; determining a playing starting frame requested by the media data request in the media data; when the playing starting frame is not the key frame, searching the key frame closest to the playing startingframe in front of the playing starting frame and the prediction frame between the closest key frame and the playing starting frame from the media data; constructing a key frame according to the searched key frame and the prediction frame; and in response to the media data request, feeding back the constructed key frame and a frame after the playing starting frame in the media data. According to the scheme provided by the invention, the delay of the fed back media data can be reduced.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a media data processing method and device, and a media data playing method and device. Background technique [0002] With the rapid development of computer technology, media data can be instantly transmitted to users all over the world when requested. In particular, in recent years, live video technology has been applied to all aspects of people's lives and work. After video data is collected in real time, it can be presented in front of users in real time, so that various social activities can be conveyed to people all over the world with the help of live broadcast platforms. Users, such as press conferences, sports events, remote conferences, etc. [0003] Usually, after receiving a media data request, the fed back media data needs to contain key frames to ensure normal playback of the media data. However, currently, after a media data request is received, the fee...
