Hi all!
I have had problems in getting screen captures from VDR (VDR 1.6.0_p2-r3 on Gentoo) with with for example:
svdrpsend.pl grab file.jpg
and Wapd, Vdr-live etc etc. I have "-g /tmp" set when starting VDR.. I actually don't remember when i lost this function, but this definitely worked at some point. I have two dvb-cards: One budget, and one full-featured card (FF Technotrend dvb-s, and Technotrend budget dvb-t)
I have read about many similar cases, and some of them got sorted out by getting more fresh dvb-drivers. These cases where from 2006, so i would assume that this issue should have been solved til now..
I also changed the order of the dvb-cards, because this seemed to be an issue at least in one case..
Now I'm using the 2.6.31 kernel with the original dvb-modules (budget_ci and dvb_ttpci).
My question is now: What else should i try to do so that i could get the grab-function to work again?
Any ideas and helps are appreciated!
Regards,
René

Hi, I'm using the plugin "screenshot" and it's running well for me.
Bye, Diego

Is there any more information in /var/log/syslog or is that the only message? Grab wasn't working for me but it was because I was using the xine plugin and didn't have a few necessary packages installed for grab to work.

The log has nothing special in it..
connect from 127.0.0.1, port 43821 - accepted closing SVDRP connection
You could have a point about the xine-thing.. I have set the xine USE-flag in my gentoo make.conf file.. I'll remove that, and recompile the whole thing. let's see if that would work..
... to be continued

No joy.. removing all xine-stuff and recompiling vdr did not help at all...

check your plugins, most plugins can block the device like the avards-plugin
Hi Thomas!
This sounds interesting! Never heard about this before.. Is there any way to check which plugins might block the device, or do I just have to start by disabling all, and going through each plugin one-by one?

Hi,
Are you sure that your FF card is the card using DVB adapter number 0 (frontend0)?
In newer driver versions, you can ensure this with options while loading the modules. Example:
modinfo dvb_ttpci
parm: adapter_nr: DVB adapter numbers (array of short)
options budget_av adapter_nr=1 options dvb_ttpci adapter_nr=0

yes, this is the best way to find it. Just start with no plugin.. when it is possible to grab the image, than one of your plugins block the device. (this is also what I did for a while: http://www.vdr-portal.de/board/thread.php?postid=809751#post809751)
Greetings and Happy New Year!

I tested everything you guys suggested, and ended up booting into older kernel-versions. I finally found a kernel-version that returned a suxxesful grab. After this i did a diff on the kernel-config-files, and found what was missing from my new configs: CONFIG_VIDEO_V4L1_COMPAT=y (Device Drivers->Multimedia support-> Enable Video For Linux API 1 compatible Layer=y)
Enabling this, recompiling the kernel, replacing the kernel-image and rebooting my vdr returned the grab-feature of vdr!!
I'm not sure why vdr 1.6.0-2 needs this setting, but anyway this solved the case.
I hope that if someone has similar problems, that these instructions help them getting grab to work again!
Best Regards, and have a merry New Year 2010 :-)
