problems with streamer / AVI files

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



I'm using an ATI T.V. Wonder VE card, which works fine. However, I have
two problems that are causing me to have issues. I've been using it as a
sort of homebrewed tivo, using the 'streamer' program that comes with
xawtv. I've also been using the mjpegtools package to edit the resulting
files (I'm encoding on the fly into mjpeg), using 'glav' to edit out
commercials. After that, I'm reencoding the mjpeg AVIs into divx4.

The biggest problem is that if I record more than 2GB worth of data in one
file, the file becomes uneditable by glav. I know that there is a 2GB
limit on AVI files, and I also know that there does exist an extension to
the AVI specification that works around this. However, 'streamer' doesn't
seem to be able to write out files in this format (or, glav can't
recognize them, but I think that streamer isn't writing out the index on
the >2GB files correctly)

This is a problem mainly because, at 320x240, and mjpeg quality of 80, 1
hour of video hovers right around the 2GB line. Sometimes it makes it
under, sometimes it doesn't, depending on what it was I was recording. So
the question is: does there exist a capture program that can write out AVI
files >2GB correctly? A corrolary to this: does there exist an editor that
can edit AVI files >2GB? If no to either of these, is there a capture
program that can write ANY video format >2GB, and is there an editor that
can edit said files?

I attemped to capture to raw video/audio , but the YUV files created by
'streamer' give the following error when I attempt to process them using
any of the YUV tools in the mjpegtools package:

**ERROR: Could not read YUV4MPEG header: bad header magic!

The second problem I'm having is just that for some reason, when I
capture, I have a black border on the left of each frame that is about 5%
of the width o the frame, and another, smaller border on the right side of
the frame, about 2% of the width of the frame. An example can be seen at
http://implausible.net/images/frame.jpg . Is there a way to fix this? It
isn't that big a deal, but it is slightly annoying.

Thanks in advance, and sorry for the large email.
