Hello, With the original install of my mini2440 Qtopia, I've got http server with 3 pages. The chinese pages USB camera not working, in the page code source I found a HTML form using webcam.cgi but this file are not present. Where I can found it? It is present in other compilation ? Thanks
Hello, I've never found it, but if you want to play with built-in cam you can try http://code.google.com/p/mjpg-streamer-mini2440/
Hello Vladimir, I Just would like to know if the built-in cam will also work on kernel 2.6.29.4? Which kernel version have you tried it? Thanks, Puma
Maybe this webcam.cgi script can be found in the Qtopia image from an old DVD version. The oldest one I have found on arm9 website is ed2k://|file|mini2440-20090220.iso|2698563584|BD3CD6411CA9666A9DF4B04CD7... Maybe it is possible to find older ones
Hello, >I Just would like to know if the built-in cam will also work on kernel 2.6.29.4? Which kernel version have you tried it? version r6 will work with standard camera driver, so either 2.6.29.4 or 2.6.32.2 is fine.
I try mjpg-streamer-mini2440 but It don't work with my webcam 0ac8:307b with command line : ./mjpg_streamer -o "output_http.so -w ./www" -i "input_gspcav1.so -d /dev/video0 -r QVGA -f r32" and the result: MJPG Streamer Version.: 2.0 i: Using V4L1 device.: /dev/video0 i: Desired Resolution: 320 x 240 video /dev/video0 Camera found: PC Camera VIDIOCGPICT brightnes=0 hue=0 color=0 contrast=32768 whiteness=26214depth=8 palette=0 Bridge found: zc3xx Not an Spca5xx Camera !! wrong spca5xx device StreamId: -1 Camera try palette 21 depth 8 Damned second try fail try palette 15 depth 12 Damned second try fail try palette 4 depth 24 Damned second try fail try palette 3 depth 16 Damned second try fail try palette 5 depth 32 Damned second try fail probe size in Available Resolutions width 640 heigth 480 Available Resolutions width 384 heigth 288 Available Resolutions width 352 heigth 288 Available Resolutions width 320 heigth 240 Available Resolutions width 192 heigth 144 Available Resolutions width 176 heigth 144 Available Resolutions width 160 heigth 120 Invalid palette in check palette fatal !!
