How do I find it? And how do I pass it to v4l? From a Linspire list I found: I used this program to fix a configuration problem with xawtv. My xawtv was not displaying any video, just a black screen with sound. To diagnose the problem, I ran xawtv from an xterm window and observed the following messsages: WARNING: Your X-Server has no DGA support. WARNING: couldn't find framebuffer base address, try manual configuration (v4l-conf -a ) I opened up the file /var/log/XFree86.0.log and searched for the term framebuffer until I found the line Linear framebuffer (phys) at 0xc000. Then, logged in as root, I ran the command v4l-config -a 0xc000 from the xterm window. Now xawtv works fine although I still get that second warning line about DGA support. Slight adjustment needed - the file that needs editing is v4l.conf, not v4l.config, and the framebuffer address is found in Xorg.0.log. Now I can get sound and vision in xawtv (tvtime still doesn't recognise the card, saying it can't open capture device /dev/video0). I've still a bit of a problem, though, as after a few seconds everything on the screen starts blinking - though not necessarily continuously. What could cause that?

Hallo I've been working happily with mjpegtools under FC4, using xawtv to monitor input/capture. Now I've installed FC6, and can't get it to work. What's the output of v4l-conf ?

You use a color depth of 24, can you downgrade it to 16 bit. I think I remember problems with 24 bit, and 16 bit worked well. That would be a setting in the X11 config. Slight adjustment needed - the file that needs editing is v4l.conf, not v4l.config, and the framebuffer address is found in Xorg.0.log. Where is that file. I didn't find it on my machine.

I wonder if it was because the audio level was set too loud? It didn't happen at all this time. The only problem I see now is in the terminal message 'Disk too slow, can not keep pace!'. Perhaps a dma issue? I'll have to look into that. Thanks, as always, for the help. Anne pgpD68wmYXxZx.pgp Description: PGP signature - Using Tomcat but need to do more?

HAllo Slight adjustment needed - the file that needs editing is v4l.conf, not v4l.config, and the framebuffer address is found in Xorg.0.log. Where is that file. I didn't find it on my machine. /var/log/Xorg.0.log Sorry for being unclear. I wanted to know the location oth the v4l.conf file, not where I find the adress. I've still a bit of a problem, though, as after a few seconds everything on the screen starts blinking - though not necessarily continuously. What could cause that? I wonder if it was because the audio level was set too loud? It didn't happen at all this time. That seems unlikely for me. Have you rebooted your system between the two tests ? The only problem I see now is in the terminal message 'Disk too slow, can not keep pace!'. Perhaps a dma issue? I'll have to look into that. With (hdparm /dev/hdX or in the /proc directory) you see if dma is enabled. The disk to slow message come on my system sometimes if I encod a video and play it back. auf hoffentlich bald, Berni the Chaos of Woodquarter Email: [EMAIL PROTECTED] www: http://www.lysator.liu.se/~gz/bernhard - Using Tomcat but need to do more?

I wanted to know the location oth the v4l.conf file, not where I find the adress. /etc/sane.d/v4l.conf I'm not sure just what that 'v4l.conf -a 0xc000' actually does - it doesn't add anything visible when you cat the file.

It seems unlikely to me, too, but I can't think of anything else that changed. No, there was no reboot. In fact I don't think I had even logged out during that time.

With (hdparm /dev/hdX or in the /proc directory) you see if dma is enabled. Yes, I checked it yesterday evening. It says it is running at udma5 The disk to slow message come on my system sometimes if I encod a video and play it back. It doesn't seem to be doing any harm. It does look as though I can carry on with my tape dvd conversions. Thanks again. Anne pgpT2U3U1wZAu.pgp Description: PGP signature - Using Tomcat but need to do more?
