Changing the major version for a field addition is not acceptable, it should be added to the end and not require that. Furthermore, I feel like the entire presence of that field in AVFrame is not a good idea. Its a very specific field, and we actively tried to remove such fields from the very generic structures like AVFrame, using side-data and other feature/codec-specific things instead. ROI itself is side-data, so this flag should be as well. - Hendrik _______________________________________________ ffmpeg-devel mailing list email@example.com https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
