Can someone tell me what are the optimal mpeg2enc/mplex settings when encoding animated video from a DVD? Animation is nothing but a bunch of jpegs i.e essentially motion-jpegs! The very essence of mjpegtools! So I would guess there are a set of magic switches that will give me optimal quality

Is there a way to combine multiple MPEG1 files (VBR) into one large MPEG1 file? The reason I ask is that I usually use dvd::rip's chapter mode to create one-per-chapter MPEG1 files to burn on a XVCD. Primarily because each chapter usually needs some minor tweaks to mpeg2enc's -q and/or -K parame

2003-11-27 Thread Ronald Bultje
Hi all, as promised, today's the great day that mjpegtools-1.6.1.92 (release candidate 3) is online. It's basically the same as 1.6.1.91, with some small changes: * config.h include reference removed from all installed header files * long command-line options now work for mplex * typo fixes Down
