Linked are some demo files. I converted a sample to DDS with texconv.exe -f DXT4 -pmalpha sample.png I converted it back to PNG against master with ffmpeg -i sample.dds master.png I converted it back to PNG against this patch with ffmpeg -i sample.dds patch.png
The color in master.png is dark due to being premultiplied twice. The color in patch.png is true to sample.png. https://connorworley.com/sample.png https://connorworley.com/sample.dds https://connorworley.com/master.png https://connorworley.com/patch.png -- Connor Worley _______________________________________________ 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".
