Logitech QuickCam Messenger & Skype

[Grof]

[Ubuntu 8.04]
Dakle, uspio sam natjerati stari QuickCam Messenger da radi pod Skype-om i to vrlo dobro! Rješenje vrijedi za sve webkamere koje daju podatke u RGB, a ne YUV standardu...
Ima malo i kompajliranja i poštelavanja skripti, no nije tako teško, a rezultat je prilično zadovoljavajući.
Napravite ovako:

Kod: Označi sve

sudo apt-get install subversion
sudo apt-get install build-essential libgstreamer0.10-dev pkg-config
svn checkout http://gstfakevideo.googlecode.com/svn/trunk/ gstfakevideo
cd gstfakevideo
make
sudo make install

Nakon toga provjerite da li ste izašli iz Skype-a (ne smije biti ikonica u trayu!)
Zatim pokrenete ovo:

Kod: Označi sve

gstfakevideo v4lsrc device=/dev/video0 ! ffmpegcolorspace

Ovo automatski pokreće i Skype i možete ovo staviti u Meni...
Sada u Skype-u pod Options podesite video, uključite ga, izađite iz Options,a ponovo uđite i Skype bi trebao prepoznati gstreamer fakevideo input i kikom na Test trebali bi vidjeti video na preview-u.

Ako je slika sa kamere loša, u krivim je tonovima (plava npr.) onda je potrebno izmjeniti kernel modul koji radi sa kamerom (driver), jer driver za kameru koji dolazi sa vanilla kernelom ne radi dobro sa ovom vrstom kamera.
Rješenje je slijedeće:
Skinite sa ove stranice zadnju verziju modula u sourceu (qc-usb-messenger-1.x.tar.gz)
Raspakirajte to u home direktorij, pa tipkajte ovako:

Kod: Označi sve

cd qc-usb*
make all
sudo make install

Nakon toga dobili ste modul i program koji se zove qcset i služi za dodatno poštelavanje kamere...
Sada je još potrebno blacklistnuti originalni modul od kernela ovako:

Kod: Označi sve

sudo gedit /etc/modprobe.d/blacklist

Kada se otvori editor na kraju teskta dodati liniju:

Kod: Označi sve

blacklist quickcam_messenger

snimiti i izaći, zatim otvoriti ovo:

Kod: Označi sve

sudo gedit /etc/modules

i na kraju teskta dodati:

Kod: Označi sve

qcmessenger

snimiti i izaći, te restartati kompjutor.

Nakon toga slika sa kamere bi trebala biti bitno bolja!

neznam dali bi to trebalo raditi na "logitec E2500" webkameri (takvu imam),
nisam uspio, a evo kaj sam radio, de sam pogrešio?

imam i "labtec"(neznam model), ima sliku, ali je pretamna, skoro se niš nevidi,
kako bi mogo nju srediti (ako se uopće može)?
