* commit 'ab35ec29a4071871934856c00da7d6ebcc0c095b':
  vf_overlay: get rid of pointless messing with timebase.

  libspeexdec: handle NULL return value from speex_packet_to_header()
  h264probe: Don't error out on bits that no longer are reserved
  mpegvideo: set extended_data in ff_update_duplicate_context()
  libspeexdec: properly handle DTX for multiple frames-per-packet
  libspeexdec: move the SpeexHeader from LibSpeexContext to where it is used
  libspeexdec: simplify setting of frame_size
  libspeexdec: set channel_layout
