[Mjpeg-users] Some more glav/lavplay problems

2004-10-27 Thread Dik Takken
Here are two more problems that I discovered while working with glav/lavplay: * When you play a very short avi with glav, glav exits when playing is finished. When you play longer avi files, glav stays open and I can edit the video. This should also be possible for short avi files. * You can't

[Mjpeg-users] mpeg2enc: progressive vs interlaced quality

2004-10-27 Thread Dik Takken
Hello, I noticed something strange while playing with mpeg2enc. When I encode a sequence of frames to progressive mpeg2, the output quality is *much* better than when I encode the same image sequence to progressive mpeg2. It seems to me that something must be wrong here. I use these options for
