> There is something wrong with this test. All the subtitles are just gone.
The test is producing two output streams:
#0: The video with the graphic subs overlaid
This is perfectly ok, just like before
#1: The same graphic subs stream mapped a second time as direct
output, which doesn't generate an output currently
I have some vague memory that ffmpeg doesn't allow to map an input
stream to an output directly when it's already used as an input
to a filtergraph - or is this supposed to work?
Thanks,
