I don't like having a platform-specific variable in the context, but I understand why it's necessary. Wouldn't a single modifier be sufficient, though, rather than exposing all supported modifiers? Since all images that are allocated by the frames context should all have the same modifier. _______________________________________________ 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".
