This prevents the situation where EOS is passed as the first frame to the
h/w decoder and thus avoids a potential crash.

This makes sure decoder->read() returns if it is the first frame fed.

It's only shadowing the AVOption with the same name.

Since RV40 is based on H.264, it uses the same interpolation filters and
functions for halfpel interpolation in one direction can be reused.
Unfortunately other cases are implemented differently and produce slightly
different output because of rounding.

This reverts commit b47904d1.

coded_{width, height} overwrites width and height in avcodec_open and
it currently just report the non-lowres size.

It was mistakenly removed in 2cf8355f,
not taking into account that new streams might appear in av_read_frame()
that avconv doesn't know about.

Fixes bug 24.

Unlike other containers RealMedia stores its audio packets in scrambled form,
with interleaver ID preceeding audio codec ID. Currently deinterleaving
decision is tied to the codec while it's possible to have non-default
deinterleaver with audio codec (like Int0 deinterleaver instead of specific
one for Sipro).

The new function provides a more generic interface than av_fifo_peek()
for peeking at a FIFO buffer data.

Pulldown flags are being set incorrectly and AVFrame->repeat_pict is not
being set.  Also, skipped frames exit header parsing too early and do not
set pulldown flags appropriately. Ticks_per_frame needs to be set and
time_base adjusted so player can extend frame duration by a field time.

This fixes problems encountered when attempting to transcode HD-DVD EVOB
files with HandBrake. Also makes these files play smoothly in avplay.

Previously, we would leave the left edge uninitialized, which led to
CBP prediction errors on slice edges, e.g. in SA10098.vc1.

This checks for sigterm but otherwise is identical to the previous
behavior.
