31bb172be2 ffmpeg: ensure that -fix_sub_duration doesnt create subtitles with zero duration 
When fix_sub_duration is used, and the duration fixing code is generating 0
duration, that is definitely zero, and not undefined or infinite (which may be
the case for decoded AVSubtitles depending on the codec), so it is safe to drop
it.

It fixes teletext subtitle sources, when the subtitles are transmitted twice
after each other for some reason.

4d6f2ff524 ffmpeg: free empty subtitles as well in transcode_subtitles 
Even if it does not matter at the moment, because subtitles with num_rect == 0
have no memory allocated, this is how we expect the users to use the API, a
returned AVSubtitle should be freed with avsubtitle_free.

d7ebeba80c ffmpeg: Do not fill gap before the first decodable frame on single stream input files unless the user explicitly requests it. 
Fixes different behavior to JM and probably several if not all
reference decoders.

We cannot just do this unconditionally as it would ruin AV sync in
some use cases.

9c52ab6f4f ffmpeg: treat avi as VFR in framerate conversion code 
It can be debated if avi is vfr or cfr, it can be either depending
on the definition of vfr and cfr.
This commit ensures that avi is treated correctly independent of
