Pico Card Image in one channel.

[effie_jayx]

I have set up a linux box with ubuntu hardy and zoneminder in the repositories.

I have a pico card I am tryin to set up, I followed several tutorial

I unload the bttv module and then I load it with

Code: Select all

sudo modprobe bttv gbuffers=32 card=77 tuner=4 radio=0 coring=1 full_luma_range=1 chroma_agc=1 combfilter=1 autoload=0 triton1=0 vsfx=0

I can only see one camera in a monitor, the other as either black or blue and the last one is a broken link.

I have tried changig resolutions to 320x240 and to grayscale, but the issue remains.

here is my dmesg

Code: Select all

Any suggestions?

All your other errors are a result of this one.
Shared memory sections are created after a valid capture and information is stored there.
If an image was not able to be captured, then nothing can be placed in shared memory.

Try using /dev/video0 instead of the symlink.
What permissions does /dev/video0 have?

Thanks I was able to fix the sahred memory issue by providing more memory by doing

Code: Select all

echo 536870912 >/proc/sys/kernel/shmall

and

Code: Select all

echo 536870912 >/proc/sys/kernel/shmmax 

I also fixed the litle typo in a resource for channel 4,

now the issue remains... only one channel with video and the other three are black with red stripes.

running Archlinux with zoneminder 1.24.2 and dont get the pico card running anymore. Due a broken harddisk i had to set up a new system.
1.23.2 was running fine since then.

I do have added the option bttv line as pastet in the wiki, but i cant get a picture out of my cam.

I do have a PAL 640x480 cam, but since there is changed so much, i dont know anymore what to do.

Ive tryed some different configurations with PAL "RGB,BGR" and so far, i ve added the shhmax to get some higher resolutions. But in no way i get a picture.
