Merge remote-tracking branch 'qatar/master' 

* qatar/master:
  avcodec: add support for planar signed 8-bit PCM.
  ra144enc: add sample_fmts list to ff_ra_144_encoder
  smackaud: use uint8_t* for 8-bit output buffer type
  smackaud: clip output samples
  smackaud: use sign_extend() for difference value instead of casting
  sipr: use a function pointer to select the decode_frame function
  sipr: set mode based on block_align instead of bit_rate
  sipr: do not needlessly set *data_size to 0 when returning an error
  ra288: fix formatting of LOCAL_ALIGNED_16
  udp: Allow specifying the local IP address
  VC1: Add bottom field offset to block_index[] to avoid rewriting (+10L)
  vc1dec: move an if() block.
  vc1dec: use correct hybrid prediction threshold.
  vc1dec: Partial rewrite of vc1_pred_mv()
  vc1dec: take ME precision into account while scaling MV predictors.
  lavf: don't leak corrupted packets
