Title:     video capture
Date:      Thu May 12 17:43:42 2005

Ahojda, 

mam kartu nvidia GeForce FX 5500 s VIVO chipem SAA7114h. Provozuji debian 
pure64 (amd). Xka mi bezi s binarnim ovladacem od nvidie, tj. mam zavedeny 
jaderny modul "nvidia" a v XF86Configu-4 mam taky nvidia. Potud zadny 
problem. 
# glxgears
12258 frames in 5.0 seconds = 2451.600 FPS
15420 frames in 5.0 seconds = 3084.000 FPS

Nyni bych rad grabnul video z VHS kazety do pc. V jadre 2.6.11 je modul 
SAA7114h. 

Loadnu saa7114h, v4l2_common, videodev, videocodec, i2c_algo_bit, 
i2c_nforce2, i2c_core

v /var/log/messages mi to videodev a videocodec vypisou hlasky:
Linux video capture interface: v1.00
Linux video codec intermediate layer: v0.2

dale existuje:
# ls -la /dev/video0
crw-rw----  1 root video 81, 0 2005-04-26 07:39 /dev/video0

a ted prijde problem:
# v4l-conf
v4l-conf: using X11 display :0.0
dga: version 2.0
mode: 1024x768, depth=24, bpp=32, bpl=4096, base=0xe0000000
can't open /dev/video0: No such device

Nechapu v cem je problem. Muze to byt v poradi zavadeni modulu do jadra? Muzou 
tomu vadit nejake jine moduly? Muze byt problem v nastaveni ovladace "nvidia" 
? 

Diky za rady a tipy :) 

Zdravi michal (toho casu ponekud strnuly)
