If I run two separate ffmpeg commands, the first one re-encoding with libx264 and outputting mpegts to udp://127.0.0.1:9036 and the next receiving from udp:9036 and converting to -f dash it throws the same error "incompatible with output codec id", yet if the encoding goes straight to the -f dash it's happy. So now the question becomes:
How do I strip the h264 stream from the ts to feed to -f dash?
