Comment (by steipal):

 Using "-an" is not an option as we need to deliver MXF files with audio
 for our playout system (Quantel). And because ffmpeg seemingly sees an
 audio track and is able to create other formats from the source, for
 example mkv (with audio) without throwing error, I assumed this would be
 the expected behavior also for the MXF muxer. I have no problem with MXF
 being "different" like I have for the last 10-11 years dealing with
 creating MXF files using ffmpeg, but usually the MXF-specific warnings or
 errors are more meaningful than this one so I was surprised. The error is
 generic and comes from the main fftools/ffmpeg.c and not
 libavformat/mxfenc.c where it would make more sense if this was MXF
 specific.
