ffmpeg: copy b frame codec delay back from decoder to demuxer
...
The demuxer needs this value to generate correct timestamps in some corner cases
Ideally the parser would always set this correctly, but some parsers lac support
for extracting this value, also its not trivial.
This fixes a regression

ffmpeg: make reading packets from thread blocking.
...
If a packet is not ready on the input selected by ffmpeg,
it will read from another input instead. If that happens
repeatedly, frames will accumulate somewhere later in the
processing to ensure streams synchronization. It can happen
in particular when reading from a slow medium or an
expensive lavfi filter graph.
Make reading from normal demuxers on non-streamed data and
from the lavfi pseudo-device blocking to avoid that.
Should fix trac ticket #3079 .

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.
