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: 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.

Allows, amongst other things, to override the size guessed

Note: the -s option could have more or less the same semantic,
but it receives a special treatment by the options system.
