Merge remote-tracking branch 'qatar/master'
* qatar/master: x86: cabac: replace explicit memory references with "m" operands avplay: don't request a stereo downmix wmapro: use av_float2int() lavc: avoid invalid memcpy() in avcodec_default_release_buffer() lavu: replace int/float punning functions lavfi: install libavfilter/vsrc_buffer.h Remove extraneous semicolons sdp: Restore the original mp4 format h264 extradata if converted rtpenc: Add support for mp4 format h264 rtpenc: Simplify code by introducing a separate end pointer movenc: Use the actual converted sample for RTP hinting Fix a bunch of common typos.
