Dotaz: problem s luvcview a webkamerou Logitech pod Debianem Wheezy

[Karlitos]

Zdravim

Postavil jsem si maly server a nainstaloval na nej Debian Wheezy (testing) - zakladni system + webserver, ftp ... tedy bez grafickeho prostredi. Chtel jsem zkusit, jestli je mozne pristupovat pomoci X-forwardingu na pripojenou webkameru Logitech (vim jde to i jinak a lepe - stremovat obraz .. - ale tohle znelo jako nejrychlejsi reseni)

Takze jsem nainstaloval luvcview - potrebovalo minimum dalsich baliku - ale kdyz ho zkousim spustit prez SSH tak mi to vypise :

luvcview 0.2.6 SDL

information: Video driver: x11

A window manager is available

Device information: Device path: /dev/video0

Stream settings: ERROR: Requested frame format MJPG is not available and no fallback format was found.

Init v4L2 failed !! exit fatal

Problem je ze nevim jestli je chyba v ovladaci a nebo jestli je to kvuli tomu ze se snazim spustit video prez SSH. Zkousel jsem i reseni LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so /usr/bin/luvcview ale beze zmeny.

Tady je jeste vypis lsmod | grep videodev

videodev 61226 1 gspca_main

media 13692 1 videodev

i2c_core 19022 6 i2c_i801,videodev,i915,drm_kms_helper,drm,i2c_algo_bit

 

Kdyby me nekdo umel poradit budu moc rad, predem diky ! K

Tak jsem udelal zajimave zjisteni. Na notebooku s Ubuntu Maverick mi ta kamera pod luvcview take nefunguje ale zato funguje pod guvcview. Ten mi vypise toto kdyz ho spustim :

guvcview -d /dev/video1

Takze nechapu kde je chyba, kdyz guvcview funguje ale luvcview ne. Mozna bude jednodussi zkusit najit nejaky uplne jednoduchy prehravac videa ale programy jako cheese nebo guvcview si tahaji hafo zavislosti.
