Great work! It is working now! Congratulations! There are some limitations: - Mplayer is working fine, the best that without LD_PRELOAD too :-) - Skype - only with your start script start script it is working too :-) (only things I had to change were library path and skype) and script name because of apparmor limits) I see that skype is working better (brightness) when I start mplayer first flash is not working (blask screen) , after LD_PRELOAD I see garbage and firefox crashed - kopete crashed Brightness is worse than in Windows (too dark picture with not very good light (bulb about 100W) LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so kopete paw...@hpw:~/webcam/microdia> VIDIOC_ENUM_FMT: Zły argument VIDIOC_ENUM_FMT: Zły argument terminate called after throwing an instance of 'std::bad_alloc' what(): std::bad_alloc KCrash: Application 'kopete' crashing... - ekiga complain about wrong video format - amsn almost works, but picture is flashing, brightnes and picture controls working dmesg usb 1-6: USB disconnect, address 7 microdia: Microdia USB 2.0 Webcam unplugged microdia: Microdia USB 2.0 Webcam releases control of video device /dev/video0 usb 1-6: new high speed USB device using ehci_hcd and address 8 usb 1-6: configuration #1 chosen from 1 choice microdia: Microdia USB 2.0 Webcam - 0C45:627C plugged-in. microdia: Detected SN9C20X Bridge microdia: Detected HV7131R Sensor microdia: Microdia USB 2.0 Webcam is now controlling video device /dev/video0 usb 1-6: New USB device found, idVendor=0c45, idProduct=627c usb 1-6: New USB device strings: Mfr=0, Product=1, SerialNumber=0 usb 1-6: Product: USB20 Camera microdia: [E] Empty buffer queue. paw...@hpw:~> mplayer tv:// -tv driver=v4l2:width=640:height=480:fps=25:device=/dev/video0 -vo xv MPlayer dev-SVN-r27637-4.3-openSUSE Linux 11.0 (i686)-Packman (C) 2000-2008 MPlayer Team CPU: Genuine Intel(R) CPU T2500 @ 2.00GHz (Family: 6, Model: 14, Stepping: 8) CPUflags: MMX: 1 MMX2: 1 3DNow: 0 3DNow2: 0 SSE: 1 SSE2: 1 Compiled with runtime CPU detection.
