I am trying to prepend a title to a short video but can't concatenate the two. I ripped the main file from a DVD as follows: mencoder dvd://4 -nosound -ovc raw \ -vf eq2=1.8:2.0:-0.15:1.0,crop=704:480:8:0 \ -ss 6 -endpos 16 -o 1.avi The title was created from many copies of a 704x480 JPG as follows: mencoder mf://*.jpg -mf w=704:h=480:fps=29.97:type=jpg \ -nosound -ovc raw -o title.avi To concatenate them, I tried this: mencoder -ovc copy -oac copy -o out.avi title.avi 1.avi This failed, apparently because of differences in depth (bpp) and/or color space: 1.avi: VIDEO: [YV12] 704x480 12bpp 29.970 fps 121529.7 kbps (14835.2 kbyte/s) title.avi: VIDEO: [444P] 704x480 24bpp 29.970 fps 243059.1 kbps (29670.3 kbyte/s) Is there any way to change the depth or color space with either of the commands shown that use "-ovc raw"? (Actually, I could even live with grayscale.) I would rather stick with a straight stream copy (-ovc raw) for the 1.avi video but could mess with encoding the title if necessary. Thanks. _______________________________________________ MPlayer-users mailing list MPlayer-users@xxxxxxxxxxxx https://lists.mplayerhq.hu/mailman/listinfo/mplayer-users
