ZM Ubuntu BT878 Help!

Post by karlpox »

Hi,

Im fairly new to linux and currently interested in trying out ZM. My current system is working fine on windows using DMMultiview. I wanted to test out ZM so I can use it on my phone since my current card doesnt support it with DMM.

I followed this thread (cant be posted) but it wasnt really complete, so I was not able to solve my problem. ZM currently does not show anything from my card, and when I try cheese it does not detect my card/camera.

I tried this command to check my bttv

Code: Select all

lsmod | grep bttv
and outputs this:


Im not sure if I am on the right track on this. But cheese not detecting anything is probably a bad sign. Any help on this?

Heres my bttv.conf

Code: Select all

options i2c-algo-bit bit_test=1
options bttv gbuffers=16 card=102,102,102,102,102,102,102,102 radio=0,0,0,0,0,0,0,0 tuner=4,4,4,4,4,4,4,4 chroma_agc=1 combfilter=2 full_luma_range=1 coring=1 autoload=0
I also tried switching it to this since I am on a 4CH card:

Code: Select all

options i2c-algo-bit bit_test=1
options bttv gbuffers=16 card=102,102,102,102 radio=0,0,0,0 tuner=4,4,4,4 chroma_agc=1 combfilter=2 full_luma_range=1 coring=1 autoload=0
I also tried updating ubuntu as well and still no luck.

Anything else I miss or need to do?

Can you do a "dmesg | grep bttv" and post the output here? If you dont get any results reboot the PC and try it again. This should be pretty easy to sort out but some more info would help a lot.

I will need to get back to you in the AM but for now make sure you are part of the "video" group in /etc/group and if not add your account and reboot or logout and back in. Then use VLC to open /dev/video0 as well as video1,2, etc and see what you get. While you are at it add the user zm runs as to the video group...should be www-data.

Also, ir you can do a "dmesg >> dmesg.txt" and post the output file on dropbox or pastebin that will help.

alright thanks. I just added the www-data to the video using this code

Code: Select all

sudo usermod -a -G video www-data
im not sure if thats correct. Then I checked with cheese and VLC still no video being detected.

and here is the pastebin for the dmesg
pdrS2EG4

Still cant post URLs. you can just append the code above to pastebin domain

It has been a while since I have messed with the bttv stuff so I am a bit rusty...

Have you tried it without any options configured for the card? If so, are you able to use VLC to open /dev/video0? What does "ls -h /dev/video*" show?

ls -h /dev/video* shows

ls: cannot access /dev/video*: No such file or directory
