Problems solved by technology
However, h264 and h265 cannot fully adapt to the transmission of ultra-low-latency streaming media data. For example, the delay requirements in cloud game scenarios are usually 1 ms-100ms
However, due to the hardware decoding support problem of the graphics card, the existing ultra-low-latency streaming media data still needs to use h264, h265 encoding protocol encoding as the main encoding protocol
Due to the lack of time slicing capabilities of the h264 and h265 encoding protocols, it is impossible to quickly identify and deal with problems such as packet loss and out-of-sequence during the transmission of ultra-low-latency video stream data such as cloud games, resulting in a large delay and performance consumption

The invention relates to a video stream data processing system, comprising a sending end, a processor and a memory storing a computer program, the system is preset with a video data packet structure, and the video data packet structure includes an additional protocol header, an RTP protocol header , additional data, RTP data, wherein, the additional protocol header includes a frame sequence number data segment, an RTP first packet sequence number data segment, an RTP packet quantity data segment and an I frame identification data segment; the additional data is corresponding to the additional protocol header The data, the RTP protocol header and the RTP data are generated based on the RTP protocol. The present invention reduces video stream data transmission delay and performance consumption in an ultra-low delay application scenario.
Description
technical field [0001] The invention relates to the technical field of data processing, in particular to a video stream data processing system. Background technique [0002] Existing video stream data is usually encoded based on h264 and h265 encoding protocols, which are suitable for video call and live broadcast video stream data transmission scenarios. The delay range of video call stream media data transmission link is usually 100ms-1s, live stream media data The delay range of the transmission link is usually 1s-10s. However, h264 and h265 cannot fully adapt to the transmission of ultra-low-latency streaming media data. For example, the delay requirements in cloud game scenarios are usually 1 ms -100 ms. However, due to the hardware decoding support problem of the graphics card, the existing ultra-low-latency streaming media data still needs to use the h264 and h265 encoding protocols as the main encoding protocols. Due to the lack of time slicing capability of the h2...
