I deal with Dolby-E PCM streams as muxed into a satellite transport stream.
It is a single stream. I extract the stream with ffmpeg into a single WAV
file, which I then read into and audio program so that I can extract the six
DD5.1 single channel WAV files. I then create an AC3 file from those six
Unfortunately I do not deal with MXF. I would find it strange if the format
required two separate WAV files, each placed into a single channel PCM file.
Especially singe the broadcast industry uses gear that deals with Dolby-E
as a two channel PCM stream (SMPTE-302M).
