* 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

@item localport=@var{port}
override the local UDP port to bind with
@item localaddr=@var{addr}
Choose the local IP address. This is useful e.g. if sending multicast
and the host has multiple interfaces, where the user can choose
which interface to send on by specifying the IP address of that interface.
@item pkt_size=@var{size}
set the size in bytes of UDP packets
