Teehee... I've been waiting for that.

And change all the syntax... There should be no issues with map x:y -
it's been there for yonks and always worked when I've needed it -
except when I needed to demux 0:24 and it only mapped 0:20. The only
problem was the new ffmpeg introduced a 100ms delay in the audio but
you can work around that too ;).

Try a -map 0:0 infront of the video decode (after the -f filetype...) first.
