输入的input_path 是一个由摄像头输出的rtsp流，输出output_path 是一个rtmp流，运行过程中会有很多如上丢包告警，导致拉取的rtmp流画面有很多马赛卡以及卡顿

看起来可能是rtsp使用了udp传输导致的丢包，程序中是否可以配置-rtsp_transport tcp参数？

HuHeng commented 10 months ago

这个应该是个format参数，可以写在ffmpeg_decoder模块传参时增加这个参数试试，dec_params内没有被模块显式处理的参数会被透传到avformat_open_input/avcodec_open2接口内的option参数里。 "dec_params:{"rtsp_transport":"tcp"}"

ffmpeg_decoder.cpp 中 获取input_path后，添加如下代码，解决了丢包问题 if (inputpath.find("rtsp://") != -1) { av_dict_set(&opts, "rtsp_transport", "tcp", 0); } 但在拉流过程中，通过调用forcer_close(),有时会导致程序core掉，应该是ffmpeg未释放导致
