CodePudding user response:

You use the pixel format is the FLV does not support, need to specify the format
Recorder. SetPixelFormat (avutil. AV_PIX_FMT_YUV420P);

CodePudding user response:

CodePudding user response:

I take a video stream in the callback function, just don't know how to use javaCV forwarded to the RTMP

CodePudding user response:

There is no way to solve.
I choose to ignore it
