* 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() Conflicts: ffplay.c libavcodec/Makefile libavcodec/dvdata.c libavcodec/dvdata.h libavcodec/qdm2.c libavcodec/utils.c libavformat/flvenc.c libavformat/mov.c tests/Makefile Merged-by: Michael Niedermayer <michaelni@gmx.at>pull/30/merge
