Anyway, I'll try everything over again with v4l2 to see if something improves. thanks for you help... -- Groetjes Japie http://japie.deserver.nl Gnu/Linux 2.4.20-wolk4.9s i686 Win98 is called Win98 because you need to update at least 98% of your hardware before it can be installed ;^) --- The SF.Net email is sponsored by EclipseCon 2004 Premiere Conference on Open Tools Development and Integration See the breadth of Eclipse activity.

Ok, since you found out where the problem was, I can give you one more advice: your problem got solved by doubling the number of lines captured (480 vs 240), but the other change (640 vs 320) is irrelevant. It's ok to capture directly to whatever horizontal res you want, since that's analogic signal, but the number of lines matters. Bottom line: you could try capturing at 320:480, and then scale to 320:240, so scaling only in one direction, saving cpu cycles. Better yet would be capturing at 320:576 (full pal) and then scale to whatever. > Anyway tanks for giving me the solution! > -- > Groetjes Japie > > > > --- > The SF.Net email is sponsored by EclipseCon 2004 > Premiere Conference on Open Tools Development and > Integration > See the breadth of Eclipse activity.

That's a filter too... In any case, if you are scaling interlaced content, mind that you can only scale deinterlaced images, so deinterlacing must be the first filter on the list, like: -vf pp=lb,scale=xxx:yyy and not the other way around. That's very important. In any case, post your complete capture command.

Hi, Are you using any filter, during capture? Because that seems like filters working on interlaced videos. That's not ossible. However, you can separate the two fields and treat them as a single image, and then recompose the original interlaced frame.

[Freevo-users] bttv/mencoder quality problem
Hello, I've been trying to get a proper recording with mencoder for a while now, and can't seem to get it right. I get horizontal colored stripes all the time. I've put some jpg's in http://japie.deserver.nl/ftp/mencoder_tv/ is somebody knows the problem or has a clue, please help me out... I'am using 2.4.24 with standard v4l bttv driver, card=24. b.t.w. with mp1e there are no stripes. -- Groetjes Japie --- The SF.Net email is sponsored by EclipseCon 2004 Premiere Conference on Open Tools Development and Integration See the breadth of Eclipse activity.
