Streaming media transmission method and system

Abstract

The embodiment of the invention discloses a streaming media transmission method. The streaming media transmission method comprises the steps that a video file is transmitted to a streaming media live broadcast server or a broadcast foreground; if a transmission error occurs, a key frame which is not later than the image frame which is transmitted at last is found in the video file; decoding is started from the found key frame; encoding is conducted by using the image frame which is transmitted at last as the key frame; the video file which is obtained after encoding is transmitted to the streaming media live broadcast server or the broadcast foreground. According to the streaming media transmission method, the key frame which is not later than the image frame which is transmitted at last is found in the video file, decoding is started from the found key frame, encoding is conducted by using the image frame which is transmitted finally as the key frame, in this way, it is guaranteed that the streaming media live broadcast server can directly decode received image frames under the conditions of network interruption and reconnection, and streaming media transmission reliability and stability are guaranteed.

Description

technical field [0001] The embodiments of the present application relate to the technical field of streaming media transmission, and in particular, to a streaming media transmission method 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. Available for viewing. Wh...

Problems solved by technology

When the image frame sent by the background processing server is a non-key frame, since the non-key frame must rely on the key frame to decode, and because the key frame is missing, the live streaming server will receive the non-key frame before the key frame discarded, resulting in incomplete streaming
