When encoding movies (in my case DVDs with acidrip which is a front-end to mencoder for DVD ripping) into the lavc codec with vcodec=mpeg4 I get horizontal, flickering lines at the bottom that are disturbing me. See the attached URL for images that show this. I've also tested other codecs for the vcodec option: mpeg1video and mpeg2video do not create these lines. I've also tested all available versions of mplayer in my portage tree (1.0_pre4-r7, 1.0_pre5-r2, 1.0_pre5-r3) and downgraded all recently upgraded dependencies of mplayer but nothing helped. A typical mencoder command line is: mencoder dvd://1 -dvd-device /dev/hdc -chapter 1-11 -aid 128 -info srcform="DVD ripped by acidrip.sf.net" -oac mp3lame -lameopts abr:br=128 -ovc lavc -lavcopts vcodec=mpeg4:vhq:vqmin=2:vbitrate=1343 -vf pp=de,crop=714:554:6:12,scale=640:-2 -o "/mnt/media/what_women_want-1.avi" I also tried to leave out scaling and splitting and the prefilter pp. Nothing helped. I can also exclude that it is an error in DVD reading since DVDs are correctly displayed when played directly with mplayer and I also recompiled it to use ogle's libdvdread. Nothing of them helped. So the only thing left seems to be the encoding. Reproducible: Always Steps to Reproduce: 1. Rip a DVD as descibed above. 2. Watch the movie 3. Actual Results: Getting flickering lines at the bottom of the movie. Expected Results: Should not be there. $ emerge -pv mplayer These are the packages that I would merge, in order: Calculating dependencies ...done!
