I'm ok with bumping vp9 encoder requirement to 1.4.0. That alone will clean a lot of ifdeffery, i bet. But don't change the other three components unless there's a similar reason for it as with vp9 enc (broken encoding or decoding prior to a certain version). _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
