If I use a -F option on mpeg2enc I have to adjust the framerate first with
yuvfps otherwise I get:
**ERROR: [mpeg2enc] Picture rate greater than permitted in specified Level
or if it works the video is very very slow. I think the -F option just updates
the headers and does not change the framerate.
Im still dealing with the stream from last weekend. But its any stream I
capturwith GATOS over about 15 minutes long and try to shrink to a more
manageable size (6GB an hour is a bit of a problem). Was have been working on
this for about a month before I started asking on listservers.
Any ideas ?
Thanks,
Stuart
