Recently, I use sample_multi_transcode to transcode&&pull a rtsp stream encoded HEVC to a streaming media server encoded h264.
I add ffmpeg to the sample_multi_transcode code for pulling stream.The program works fine.But when i play the dst url,error happend. Either I use vlc or ffplay ,the screen is black. The ffplay report like this:
