Hi I am using FFmpeg for generating a D-10 file with 8ch audio (16bit). Typicall the Audio is always PCM but sometimes some dualchannels are is a Dolby-E pair. Is it possible to set a metadata flag for Audio channels to give the decoder which opens the final MXF the information that it should decode Dolby E and not PCM on e.g Ch5 and Ch6? Example D10 file with Dolby E is 1 stream video (0:0) 1 stream audio with 8ch (0:1): ch1 PCM ch2 PCM ch3 PCM ch4 PCM ch5 Dolby E (encoded as PCM), needs a "Dolby E"-flag ch6 Dolby E (encoded as PCM), needs a "Dolby E"-flag ch7 PCM ch8 PCM Any hints and tipps are welcome :) br Christoph
