<div>Hi Xuefeng</div>
<div> </div>
<div>Thanks for your patch, there's a few thing I'd like to see changed though</div>
<div>to get started.</div>
<div> </div>
<div>Begin by splitting the 12-bit support into a standalone patch, and the</div>
<div>AVC-Intra extensions into another patch on top of that.</div>
<div> </div>
<div>There's also a lot of code duplication going on here. You should try to</div>
<div>extend the existing AVC-Intra code at</div>
<div>https://git.videolan.org/?p=x264.git;a=blob;f=encoder/encoder.c;h=79997b96ef82fda8838e1eaeeeb7551a3d1aa651;hb=HEAD#l650</div>
<div>instead of using those apply_* functions.</div>
<div> </div>
<div>Henrik</div>

<div>Subject: [x264-devel] [PATCH] Fix ffmpeg AVC-Intra encoding with</div>
<div> libx264 in mov container</div>

<div> </div>
<div>For x264 encoding in mov container ffmpeg sets x264 parameter b_repeat_headers to 0 and calls x264_encoder_headers which calls x264_sei_version_write function. Both is not allowed for AVC-Intra. Since other applications may behave similar it´s better to avoid this here.</div>
