Hey that's pretty cool. I'll check that patch later.
BTW, how about updating drawtext filter so it can pick the timecode
information from metadata? We already have drawtext code handling
timecode printing.
This should already be possible using a filter string like
'drawtext=fontfile=...:text=%{metadata\\:lavfi.readvitc.tc_str}'
and with the patch from [1] you can even do
'drawtext=fontfile=...:text=%{metadata\\:lavfi.readvitc.tc_str\\:--\\\\\\:--\\\\\\:--\\\\\\:--}'

Tobias
