Re: [FFmpeg-devel] [PATCH] avformat/movenc: Add support for more colorspaces
Actually QT has supported these codepoints for some time now internally, but not officially. That said, I modified this to write nonsense values and it interpreted everything as Rec 601 625 aka 470BG, which isn't great (I think the default for anything should be 709 these days) but is not crazy either. I presume the same behavior applies to very old versions of QuickTime looking at these new codepoints.

What happens if new files (with new colorspace etc.) areplayed back with older QT? Carl Eugen ___ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
