Hi,
is there a way to mux an mxf file only containing a pcm audio stream? When
You could try using the op-atom muxer as it looks like your command is defaulting to op1a. Add -f mxf_opatom to your command line. ffmpeg -i /Users/krueger/lesspain/samples/software/compressor/ compressor4_1080_25p_apple_devices_best_compat_2s.m4v -vn -c:a pcm_s16le -f mxf_opatom ~/tmp/ffmpeg_pcm16_rewrap.mxf
[...]
Is this a conscious limitation of the muxer or am I missing a command

It looks like it. The reasons why I suggested trying OP-Atom is that this seems to be performing a specific check for OP1a.
Which is wrong, btw. There is a spec for MXF_OP1a_AES3 to wrap the respective audio without a picture essence. I would guess MCA labels will have to be provided though, and also the audio samples would have to be formatted to AES, which ffmpeg afaik currently doesn't do. Best, Erik
