I'd say that the current default (jpeg chroma loc for untagged) is more likely to be wrong than right in practice. It is definitely a change but while we're fixing lots of color related issues the next major release this might be a good time to draw a line in the sand and fix the defaults going forward to be the typical case (while perhaps trying to minimize the instances that hit this default path and warning loudly when it does). That said this seems like the kind of change that should be in a 7.0 release rather than a 6.1 release if a 6.1 is going to happen. - Cosmin _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-request@ffmpeg.org with subject "unsubscribe".
