Code stream error detection and feedback method and system based on GPU

The invention discloses a GPU-based code stream error detection and feedback method and system, and the method comprises the steps: obtaining the frame information of all frames in a video code stream according to the video code stream received from an AP end; and performing error detection on each frame one by one according to the frame information corresponding to each frame in the video code stream, and processing the current frame by querying a judgment instruction of the AP end on the error type of the current frame. The system comprises a receiving module and a detection module. According to the technical scheme, different error matching types are fed back to the AP end according to different errors detected in the video code stream, invalid hardware decoding can be reduced, decoding efficiency can be improved, and error processing interruption or resetting of hardware caused by the error code stream can be reduced. 本发明公开了一种基于GPU的码流错误检测和反馈的方法及系统，方法包括：根据从AP端接收的视频码流，获取所述视频码流中所有帧的帧信息；根据所述视频码流中各个帧对应的帧信息，对每一
