This caused mpv (and possibly others) to fallback to software decoding after
seeking a VC1 stream.

Optimized for the default filter length 16.

30% faster opus silk decoding.

Required for arch optimized resampling.

Some applications really mean to send negative pts.

No point in sending the message multiple time.

Messages should start with a capital letter and possibly end with a "."
if they are statements.

From the ARMv7 NEON version. 16 times faster as the C version, overall
more than 12% faster vorbis decoding on Apple's A7.

30%/25% (fixed/float) faster mp3 decoding on Apple's A7. The floating
point decoder is approximately 7% faster.

Approximately as fast as the ARM NEON version on Apple's A7.

Approximately as fast as the ARM NEON version on Apple's A7.

The parser has no way of knowing video duration, and therefore no video
parsers set it.

Currently, if a decoder sets AVFrame.pts, we'd send the same timestamp
to it twice, which is wrong.

It is not supposed to be changed from outside of lavc.
Set the stream timebase and average framerate instead.

The picture slot can be recycled by select_input_picture and
only current_picture is populated with the valid pts.

Unbreak timestamps when in cbr mode.

Also set the RGBA pixel format correctly as the native endian format,
which is what it returns.

This fixes the tests on big endian.

avctx->coded_{height,width} will always equal h->{height,width} since
init_dimensions() does that explicitly, Size changes are detected by
changes in mb_{height,width} earlier and propagated through the
needs_reinit variable.
