I've only ever worked with RGB DPX files in ffmpeg, but it's interesting that the Library of Congress lists YCbCr as one of the potential components. http://www.digitalpreservation.gov/formats/fdd/fdd000178.shtml#identification "Each DPX file represents a single image with a single component, e.g., luma, or multiple components, e.g., red, green, blue; or Cb, Y, Cr (chrominance-luminance data)." Imagemagick also appears to support YCbCr in DPX? http://www.imagemagick.org/script/motion-picture.php There is a list of YCbCr formats listed in the header info, but this could just be provenance info rather than actual information about the file? http://www.fileformat.info/format/dpx/egff.htm#DPX-DMYID.3 _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user
