ffmbc: stereo to 2-mono-streams in MXF OP1a

[peter_b]

Haven't verified it completely yet, but this should create a proper XDCam HD422 MXF (OP1a) from a regular stereo source. Each audio channel from the source is mapped an individual audio stream in the output:

Code: Select all

$ ffmbc -threads 8 -i FILE_IN -s 1920x1080 -tff -target xdcamhd422 \
-acodec pcm_s24le -ar 48000 -f mxf output.mxf \
-acodec pcm_s24le -ar 48000 -newaudio \
-map_audio_channel 0:1:0:0:1:0 -map_audio_channel 0:1:1:0:2:0
