This does the job: mencoder -oac lavc -ovc lavc -of mpeg \ -vf scale=480:480 -srate 48000 \ -af lavcresample=48000 \ -lavcopts vcodec=mpeg2video:keyint=18:vrc_buf_size=917:vrc_minrate=2500:vbitrate=2500:vrc_maxrate=2500:acodec=mp2:abitrate=224 \ -ofps 30000/1001 -o /dev/video16 dvd:// But it turns out that it's even slower than playing via XV and produces choppy output, no matter how I adjust the quality. Go figure. I guess it's just not optimized for the job or something. -- Jesse Guardiani Programmer/Sys Admin [EMAIL PROTECTED] ------------------------------------------------------- SF.Net email is Sponsored by the Better Software Conference & EXPO September 19-22, 2005 * San Francisco, CA * Development Lifecycle Practices Agile & Plan-Driven Development * Managing Projects & Teams * Testing & QA Security * Process Improvement & Measurement * http://www.sqe.com/bsce5sf _______________________________________________ ivtv-devel mailing list ivtv-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/ivtv-devel
