The libv4lconvert library seems to be dependent on V4L version 2. If someone could show me that I am wrong, it will be different of course.

I hoop this explains more clear. (see note at the end) I have the same problem with the philips cams, i.e. PCVC645, and flash (adobe) and i'm using flashcam package http://flashcam.sourceforge.net A project to make Adobe Flash for Linux support V4L2 webcams or video devices. I avoid using adobe products in general (not free, super-bloatted, unexistant security (a very small worm is enough to activate it and spy you through flash webcam/mike facility); and you don't know what is transmitted to adobe), and flash in particular, as it don't have *any* interest in it. (the only thing it does very well is making my old CPU jump straight to 100% each time I'm obliged to use it.) In my case the page use flash for connection and audio/video streaming and flash could not find the v4l2 device. Avoiding is no option in this case.You may say go not to that site. How when it is intra-web site of my employer? It's using a modified vloopback from the motion project. This is in use for webcam on the intraweb site. I successfuly installed Ekiga in many places: it is fully m$n compatible, can uses many sound codecs, and the H264 video mode has really an amazing quality (on a LAN, and if you have a good WC, you're close to DVD quality:) Try it, you'll love it. I avoid such applications as mush as possible. I need a computer for work not for ammusement, then I go to the cafe/bioscoop/theater etc :) Ron_1st JY_666th Anyway some driver/modules of video devices give the v4l1 and/or v4l2 interface, the philips cam in my case only v4l2. I do have a microscoop (microdia) and that on is also v4l2 only. My TV-Card (terratec) using the bt8x8 driver returns both interfaces. Another cam just only v4l1 as interface, and bad quality picture too. Some applications have the same problem for using v4l1 and/or v4l2. What to do if applicaton support only v4l1 and the cam the other one? 1) The vloopback is for programs using the v4l1, and _not_ v4l2 for using the v4l1 API to talk to a v4l2 API. 2) Flash support only v4l1 and with _specific settings_. In my case flashcam does 1 and 2 together. Good solution for me. Note: The gb.v4l component was written by Daniel C. for his v4l1 cam. Gareth did however had a v4l2 cam and he rewrote a part of the component and released a test application that uses his modified driver. So ATM I would say the gb.component is more or less broken/incomplete. If your cam is v4l1 only then you should use the D.C. version. If your cam is v4l2 only then you should use the Gareth version. This is what happend in the background of the component and the v4l2 is only for the cam of Gareth implemented, i.e. the colorspace. Both are written for specific WC with very restricted capabilities. My active involvement ATM is only for the modified code of Gareth, specific the compile time error/abort, about undefinied variable names/values for some videodev.h versions. I solved my other wishes/problems with hardware solution instead of software. Best regards, Ron_1st -- -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.

Regards, I know what should be done: with v4l is developed a library named libv4lconvert that does all the conversion stuff.
