http://en.wikipedia.org/wiki/Chroma_subsampling basically, 4:2:0 has half the color information with regard to 4:2:2, which in turn has half the color information in regard to 4:4:4. If your application is not depending on color information, like for example with chroma keying, you can probably get away with 4:2:0, which is the most commonly used in video. - Arjan _______________________________________________ libav-user mailing list libav-user@mplayerhq.hu https://lists.mplayerhq.hu/mailman/listinfo/libav-user
