Set picture type before calling get_buffer.
This allows the DR application to make better decisions.
It also fixes a resource leak in case of missing reference frames
since it would call get_buffer but never release_buffer.
Also use FFSWAP to ensure that the AVFrame is properly initialized
in the next get_buffer (in particular that data[0] is NULL).

v4l2_fd_open is already called at the end of v4l2_open;
calling a second time leaks structures inside libv4l2.

Convert them to zigzag order, as the rest of them are.

When I was adding support for 10-bit DNxHD, I just copy-pasted the
missing quant matrices from the spec. Now it turns out the existing
matrices in dnxhddata.c were in zigzag order. This resulted in wrong
quantization for 10-bit DNxHD. The attached patch fixes the problem by
converting 10-bit quant matrices to zigzag order.

This happens with for example mplayer.
Fixing it in ffmpeg allows new ffmpeg to be compiled with older mplayer
which would not be possible if the fix was just in mplayer.

OpenJPEG can decode in lower resolution or decode only a number
of enhancement layers.

The new function is called avformat_match_stream_specifier()
and does not include logging the error message.

Opus in Matroska is still a draft.

This patch also introduces CODEC_ID_OPUS.

Reap buffers stored in the buffer sinks even when
the avfilter_graph_request_oldest() loop only returns EOF.

avfilter_graph_request_oldest() can cause frames to arrive
to the sinks even when it returns EOF.

This caused ALAC to fail since the last merge

It already skips any extra bytes at the end, and apparently there are some
samples in the wild with larger 'kuki' chunks.

Needs to be done separately for each element.

An help message tells what an option does, not what its argument is.

If skip_samples is set and timestamps are synthesized using durations,
make them start at -skip_samples (rescaled) instead of 0,
so that the timestamp of the first undiscarded sample is 0.
