Problems solved by technology
[0002] In the process of real-time video transmission based on broadband network, there are problems such as out-of-sequence, packet loss, delay or jitter. These problems directly affect the effect of video stream decoding and playback, and may cause delays, blurred screens, and freezes. ; These problems can be solved by using the jitter buffer. The jitter buffer is a shared data area that can handle data packet loss, out-of-order or delayed arrival, and smoothly output data packets / frames to the decoding module; traditional Jitter buffer (Jitterbuffer) design is mainly a chained linear storage structure, and the algorithm complexity in sorting, framing and packet loss detection of video streams is relatively high

The invention discloses a video transmission method and device and a computer readable storage medium, and the method comprises the steps: receiving a video data package through a package receiving thread, and storing the video data package to a corresponding position of an annular buffer region in a pre-distribution mode; framing the video data packet in the annular buffer area by using a framing thread to obtain a code stream frame; and scanning the annular buffer area in real time by using a packet loss detection thread so as to carry out packet loss detection. In this way, video transmission can be carried out safely and efficiently.
Description
technical field [0001] The present application relates to the field of communication technologies, and in particular to a video transmission method, device, and computer-readable storage medium.
