> 主题: [FFmpeg-devel] [PATCH v3] fate/png: add mDCv and cLLi read and write test
> 
> This test confirms that we can write mDCv and cLLi chunks and read them
> back via the png decoder. It uses an HEVC conformance sample with this
> metadata as the base source for the side data in the frames.

Hi，all：
fate fails sinc e30bc8a963eab1097bfb985351ca7eaf1f272ba6. I tested on Arm and X86, there existed, too. Or, maybe I missed something else ? I am not knowlegeable enough to fix this. Thx.
