You need to add the same to the DCHECK in media/blink/skcanvas_video_renderer.cc
NewSkImageFromVideoFrameNative and deal in some way

I'm not sure how to deal with it there, let me look into that when splitting
this patch.

     DLOG(ERROR) << "Unsupported pixel format supported, got "
                 << VideoPixelFormatToString(format);
     return nullptr;
