BTTV card, how to set this up within ZM.

[mad-max]

Hi,

I got ZM working with axis cam and with Logitech webcam and now I'm trying to use a Hauppauge WinTv BTTV card with composite input.

I need to use the composite input. Using MoTV I can select composite1 for input and this works. But now I need to configure ZM to use the composite input.
video device is: /dev/video0 but what channel do I have to select?
What resolution should I use? I experienced that using the wrong resolution causes problems with an axis 2100 so I think it will also do this with bttv.

Can I select somewhere within linux the composite input as standard input? Using Suse 9.0. I couldn't find something usefull about this on internet. Maybe some suggestions?

Thanx.

It's been a while since I screwed with bttv in linux, but I thought you chose your input through the format number... 0 = pal, 1 =ntsc, 2 = composite? I remember it was something like that in xawtv... don't know if those numbers were format or channel though... hope this helps.

I got it setup. This is how to do it:

Device Channel : 2
Device Type: 1 for Pal (or 2 for NTSC)
Capture width: 320
Capture height: 240

Restart your system and THEN start the ZM processes. I've used these settings before but they didn't work. Just this morning when I restarted the system and FIRST started the ZM processes, the camera came on !!

Just one question left. When I use another resolution then 320x240, the camera won't come on. Anybody knows what resolutions are possible except this 320x240 with BTTV ?

I've one other question for the writer of the program, Why haven't you documented this simple settings? It will help people to setup their system and make ZM more interesting to use. Further, it is a very nice program Thanx !

Device Channel : 1

Sorry !

Hi Alexander,

Which bit are you saying isn't documented?

One of the reasons why changing resolution to a larger size doesn't always work on the fly is because the shared memory segment needs to be resized and if something else is attached to it then it can't be. The best solution in this case is always to restart ZM after changing the image size and then you should see it work.

I should add this to the FAQ I think.

Hi Phil,

Thanx for answering. I think the things like you told me and what I wrote here should be in the manual. Just describe how to setup a BTTV card with ZM (not within Linux, that should work) and how to select composite and so on. Telling people to restart should fix a lot of problems. Because testing and changing things without restart won't make difference :(.

Also things like how to setup an axis 2100 camera with the path and so on. This is now written in one of the forums here but actually it should be on the manual.

For now, I think the program is working great. Thanks !
Just waiting for a schedule function within the program (to switch it on/off for opening hours for example) and to delete the oldest images when diskspace is running low automatically.
