Code Issues Releases Activity

Merge remote-tracking branch 'qatar/master'

Browse Source 
* qatar/master:
  rtmp: Support 'rtmp_live', an option which specifies if the media is a live stream.
  av_samples_fill_array: Mark unmodified function argument as const.
  lagarith: add YUY2 decoding support
  Support decoding unaligned rgb24 lagarith.
  dv: Split profile handling code into a separate file.
  flvenc: use AVFormatContext, not AVCodecContext for logging.
  mov: Remove write-only variable in mov_read_chan().
  fate: Change the probe-format refs to match the final text format committed.
  fate: Add avprobe as a make dependency
  Add probe fate tests to test for regressions in detecting media types.
  fate: Add oneline comparison method
  qdm2: clip array indices returned by qdm2_get_vlc().
  avplay: properly close/reopen AVAudioResampleContext on channel layout change
  avcodec: do not needlessly set packet size to 0 in avcodec_encode_audio2()
  avcodec: for audio encoding, reset output packet when it is not valid
  avcodec: refactor avcodec_encode_audio2() to merge common branches
  avcodec: remove fallbacks for AVCodec.encode() in avcodec_encode_audio2()
