It seems that, as MPEG-TS is built to transport most anything, unknown
codecs are mapped to private data streams. You could request that a
message is provided when that happens, nothing of the sorts is
currently printed.

Furthermore, ffmpeg's output is "lying", because the details it prints
for the output are valid *before* the muxer, it doesn't (and perhaps
can't) reflect what the muxer does with it.
