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.

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.

It should not matter for real-life usage, it is just cleaner this way.

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.

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
the AVFMT_VARIABLE_FPS value.

EOF is not a fatal condition, it is normally produced
by a few filters.

TODO: take it into account to avoid useless decoding.

The ist->pts value at this point does not necessarily match the actual packet
pts, which is what should be used to decide whether to discard the packet.
Without this change, some video packets that have pts on or after the start
time are getting discarded when they should not be.
