你好,我使用cnvideo系列的api解码RTSP实时视频流。
获取到avpacket后送入cnvideoDecInput:
memset(&_streamInfo, 0, sizeof(cnvideoDecInput)); if (!avPacket.data || avPacket.size <= 0 || eof) { printf("receive null packet,notify stop decoding\n"); _streamInfo.streamBuf = nullptr; _streamInfo.streamLength = 0; _streamInfo.pts = 0; _streamInfo.flags = CNVIDEODEC_FLAG_EOS; } else { _streamInfo.streamBuf = reinterpret_cast<u8_t *>(avPacket.data); _streamInfo.streamLength = avPacket.size; _streamInfo.pts = avPacket.pts; _streamInfo.flags = CNVIDEODEC_FLAG_TIMESTAMP;//CNVIDEODEC_FLAG_END_OF_ ,CNVIDEODEC_FLAG_TIMESTAMP } ret = cnvideoDecFeedData(_handle, &_streamInfo, -1);//10000
并在回调函数处理cncodec ,解码可以成功,并得到预期结果
-------------------------------------------------------------------------
当需要停止实时解码视频流,调用以下接口停止解码,在cnvideoDecStop报错:
cnvideoDecStop(_handle);
cnvideoDecDestroy(_handle);
错误信息:
[ERROR] - [CambriconCodec] cnvideoDecStop
[ERROR][CODEC-HAL][cnvideo_device.cpp:73(PollOutProc)]guid_=41 Poll returned error event, poll status(1).
[ERROR][CODEC-V4L2][cnvideo_v4l2_ioctl.c:940(SendStopCmd)]Failed to send stop command.

希望能得到您的解答
