Peter, > On the page http://mxhaard.free.fr/camera.html "The Story of Two Little > Cams" you write that jpeg is not supported by the kernel, does this mean > that v4l cannot be used (in my case 2.4 kernel)? As far as I understand, > most webcam software hooks into the v4l API. spca5xx is fully compliant with the v4l1 API .To benefit of the jpeg stream encoded by the hardware we only extend the v4l API with our own palette jpeg . That way the spca5xx module only add the missing header and forward the full jpeg stream in user space. For all others palette the spca5xx module decode the jpeg stream in kernel space with the help of a tasklet :) ofcourse you need a strong Linux Box to work that way, i used a 2.2Ghz Athlon CPU and can work with two jpeg webcam at 640x480 with 15 fp/s :) > (Since spcaview doesn't work for me (yet), I'm looking for another > program, in particular since I want to set up something for remote > viewing through a webserver.) The best should be to used spcaserv in the same package as it forward the stream in MJPG, there are an java applet for the client size to setup in your webserver look at the spcaview package a all in one :) For the resolution i did not know some spca500 works in 640x480 other in 352x288 depend of the Sensor. I have chek for the i2c slave sensor address in debug mode, but your log say that the chip did not answer and return 0x00 :( regards -- Michel XhaardReceived on Fri May 20 2005 - 22:20:26 CEST
