Dotaz: Logitech C110 - Raspberry PI

[pou]

Ahoj,
koupil jsem si uvedenou webkameru, odzkoušel na stolním PC (debian Wheezy) vše okamžitě fungovalo (plug and play).
Ovšem na Raspbianu mi nefunguje. Můžete mi prosím poradit??

Pokud zkusím přehrát video ve vlc, píše chybu:
ALSA lib pcm.c:7339:(snd_pcm_recover) overrun occurred
Při použití programu motion mi to psalo, že kamera je zaneprázdněná, podle návodu navod jsem zakomentoval některé řádky v /lib/udev/rules.d/60-persistent-v4l.rules, tuto chybu už to nepíše ale zase nefunguje(změnu jsem vrátil zpět).
A nakonec přehrátí pomocí mplayeru ukazuje zelenou obrazovku...

neni problem s napajenim? mas raspberry s polyfuse nebo bez? zkus kameru pripojit ne primo, ale pres napajeny usb hub

[pou]

Díky za odpověď
polyfuse noo tak to nevím :-/ koupil jsem ho před Vánoci a napájím ho adaptérem přímo od výrobce.
Hub s napájení nemám, na Raspberry nenám připojený nic než tu kameru. Ta snad takový odběr mít nebude ne??
Dioda na kameře indikuje, že je používaná....

[Trubicoid2]

Polyfuse jsou tri, f1 a f2 pro dva USB porty jsou na v2 hardware vyrazeny. F3 v napajeni zustala. Koukni treba na https://plus.google.com/app/basic/photos/109928236040342205185/album/5759264418828082833/5780498170375008498?banner=pwa&gpsrc=pwrd1

Jestli tam ty f1 a f2 mas, tak zkus skratovat. Ten napajenej hub taky neni moc drahej.

[pou]

Tak jsem dnes koupil ten napajeny hub a zkusil.... ale vysledek porad stejny, na kamere se rozsviti led (indikace ze snima) ale zase nic... nejake dalsi napady??

Tak jeste dalsi poznatek, pokud zmensim rozliseni tak se obraz objevi (sice barvy jsou hrozne), rozliseni na klasickem debianu bez problemu 1024 x 768, na raspberrym se nezobrazi obraz kdy z je rozliseni vetsi nez 400(asi)

[trubicoid2]

jednak c110 ma prej tzv. bandwidth bug, zkus http://www.ideasonboard.org/uvc/faq/#faq6 UVC_QUIRK_FIX_BANDWIDTH

druhak tu se pise, ze mu na raspberry nejede c110 s obrazem vetsim nez 320×240 http://sirlagz.net/2013/01/07/how-to-stream-a-webcam-from-the-raspberry-pi-part-3/
