In normal picture decoding this does not need to be checked but as
error concealment is run in the case of errors the availability of
references is less certain. This may be fixed differently at some
point so that all references are always filled in before the EC
code, in which case this should then be changed to an assert()

* hexene/stagefright:
  libstagefright: avoid memory leak
  libstagefright: support more output pixel formats
  libstagefright: avoid potential deadlock on output MediaBuffer
  libstagefright: explicitly set positive timestamps as stagefright expects them so
  Merge branches 'stagefright' and 'stagefright-test' into stagefright-test

Fixes ticket #1228.

* qatar/master:
  ppc: drop unused function dct_quantize_altivec()
  mpegaudiodec: Do not discard mp_decode_frame() return value.
  matroska: do not set invalid default duration if frame rate is zero
  mkv: use av_reduce instead of av_d2q for framerate estimation
  mkv: report average framerate as minimal as well
  avcodec_string: Favor AVCodecContext.codec over the default codec.
  cook: Make constants passed to AV_BE2NE32C() unsigned to avoid signed overflow.

Maintain an output queue of AVFrames instead of MediaBuffers
so that the latter can be released early. This avoids a potential deadlock
between the stagefright decoder::read() and Stagefright_decode_frame()

This fixes crashes with frame threads caused by inconsistent context parameters.

Fixes Ticket1207

This also allows dropping some PPC-specific ugliness from dsputil.[ch].

This fixes the warning:

If a video track specifies a zero frame rate (invalid but occurs),
this results in a division by zero and subsequent undefined conversion
to integer.  Setting the default duration from the frame rate only
if the latter is greater than zero avoids such problems.

This is in line with other demuxers and overall seems more correct
than assuming codec time base.

* qatar/master:
  aacenc: Fix issues with huge values of bit_rate.
  dv_tablegen: Drop unnecessary av_unused attribute from dv_vlc_map_tableinit().
  proresenc: multithreaded quantiser search

  avconv: only set the "channels" option when it exists for the specified input format
  avplay: update get_buffer to be inline with avconv
  aacdec: More robust output configuration.
  faac: Fix multi-channel ordering
  faac: Add .channel_layouts
  rtmp: Support 'rtmp_playpath', an option which overrides the stream identifier
