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.

Ideally all x264 private options should be generated automatically, but
x264 doesn't provide the API for this yet.

It's broken and serves no purpose as it's a read-only field.

This makes the code simpler to understand, though it results in an
unnecessary call to avcodec_find_decoder() if the stream won't be
decoded.

libmp3lame if available, ac3 otherwise.

Clarify with an example what the user should use instead of the
deprecated (and no longer working) -s/-pix_fmt options.
