Ugh... no, it's not so simple. Some clarifications: 1) For the sake of precision, the colorspace is "Y'CbCr", not "YUV". 2) The chroma channels are not at the same resolution as the luma channel (4:2:0 subsampling) and to make them the same resolution requires upsampling. The yuv4mpeg(5) manpage describes the YUV4MPEG2 stream format. See http://www.mir.com/DMG/ for additional information on colorspaces and subsampling standards, and links to even more information on the same. -matt m. ------------------------------------------------------- This SF.net email is sponsored by: SF.net Giveback Program.
