Abstract

The embodiment of the invention discloses a video playing method which comprises the following steps: receiving adjusted playing time; searching a key frame not later than the adjusted playing time in a video file; performing decoding from the key frame; starting playing from an image frame corresponding to the adjusted playing time. According to the embodiment of the invention, the key frame not later than the adjusted playing time is searched in the video file, the video file is decoded from the key frame, and the image frame earlier than the adjusted playing time is ignored, so that accurate playing is realized.

Description

technical field [0001] The embodiments of the present application relate to the technical field of video playback, and in particular, to a video playback method, system, and streaming media playback method, device, and system. Background technique [0002] Transmit multimedia information such as audio / video on network, mainly contain two kinds of schemes of downloading and transmission as a stream. Transmitted audio / video files are generally all large, so the storage capacity required is also large; at the same time, due to the limitation of network bandwidth, downloading often takes several minutes or even hours, so the delay in this processing method is also very large. During streaming, time-based media such as sound, video or animation are transmitted continuously and in real time from the audio and video server to the user's computer. The user does not have to wait for the entire file to be downloaded, but only needs a few seconds or tens of seconds of start-up delay. ...
