Hi, I'm having some problems with colorspace in MPlayer which is best demonstrated by way of example. If I take a single JPEG and copy it to a sequence, input.0001.jpg - input.0004.jpg in the current directory, and encode it to an MJPEG... mencoder "mf://input.*.jpg" -o out.mov -ovc lavc -lavcopts vcodec=mjpeg ... then rip the resulting movie back to JPEGs : mplayer out.mov -vo jpeg I see an appreciable difference in intensity between my input frames and the ripped frames when viewed under identical conditions. Even if I view the movie directly in mplayer, I still see that its intensity does not match my input. I've tried a few different movie players and mplayer seems to be the only one which shows this difference. Am I perhaps missing some options to either one of these two commands, or is there something else going on here? Thanks in advance, Mark
