AVFrame->color_range? But even if I were using full range file (I do not) that would force BT.601 full range matrix (that is JPEG matrix) and I have the opposite here, BT.709 is forced.
I suppose the problem can be checked with simple printf of frame->colorspace with that sample that uses BT.601. This one: https://trac.ffmpeg.org/attachment/ticket/9167/2.mp4 It should be wrong at that point. Or use breakpoint in debugger. :) Also, BTW, Nvidia drivers windows 10, what is matrix used for 4K YCbCr formats by default? Is it already BT.709? Because xvYCC can be both BT.601 and BT.709 (but it is only limited range, even if full is set by mistake, see latest "ANSI/CTA-861-H") and sYCC with selectable quantisation uses BT.601 even on 4K! But those are so called digital formats, they should be further forced. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
