Since audio and video filters are explained together and share most code,
the multimedia filters section seems more fitting.

The file contains the asetpts audio filter.

* qatar/master:
  doc/APIchanges: add an entry for codec descriptors.
  vorbisenc: set AVCodecContext.bit_rate to 0
  vorbisenc: fix quality parameter
  FATE: add ALAC encoding tests
  lpc: fix alignment of windowed samples for odd maximum LPC order
  alacenc: use s16p sample format as input
  alacenc: remove unneeded sample_fmt check
  alacenc: fix max_frame_size calculation for the final frame
  adpcm_swf: Use correct sample offsets when using trellis.
  rtmp: support strict rtmp servers
  mjpegdec: support AVRn interlaced
  x86: remove FASTDIV inline asm

Also fill in missing dates and hashes.

The Vorbis encoder is always VBR.

This generates output with bitrates similar to libvorbis for a given quality
value.

Fix a memleak that the recent change of architecture made
more likely to happen.

Fixes crash on x86 due to alignment requirements for w_data in
lpc_apply_welch_window_sse2().

The same should be done with the predict output.

They were only roughly adapted when error return was
added to the push functions.

Return AVERROR_EOF if all outputs are closed.

It will avoid a forward declaration.

It will help forward errors and maintain consistency.

It reduces the lifespan of buffers in filter graphs,
and therefore the memory consumption.

Fixes invalid reads when encoding mono streams when trellis is used.

In order to send or receive a stream FCPublish, FCSubscribe and _checkbw
are completely optional and often not implemented. releaseStream over a
non-existen stream might report an error instead of being silent.
