Logitech QuickCam Pro 4000 on x86 android

Yuv420 data can be obtained from webcam through ioctl.
Before encoded to jpeg image the yuv420 data needs to be converted to yuyv, i.e. yuv 4:2:2 format.
Since converter and encoder are ready, jpeg image can be produced.
However the preview can't be seen because it could probably be turned off in gingerbread-x86 while it is turned on in froyo-x86  but causes errors.
Working on preview function.

  • yuv420 to yuyv colorspace converter migrated from guvcview to android.
  • jpeg encoder migrated from guvcview to android.
  • picture functions.
  • working on preview function.

rt3070 wifi chipset integration on x86 Android

Porting rt3070 following http://blog.linuxconsulting.ro/2010/04/porting-wifi-drivers-to-android.html
Status and ideas is sorted out below:
  • rt2870sta is loaded for rt3070 chipset when kernel starts.
  • rt2870sta is loaded again when android wifi HAL starts.
  • Disable rt2870sta in kernel configuration and make android wifi HAL load rt2800usb, rt2800usb works fine for rt3070 chipset.
  • Perhaps rt2870sta works fine if it is just loaded once, how to make rt2870sta loaded just once?
  • There is password remembering issue on rt2800usb.Wifi can now automatically reconnect to AP, providing wpa_supplicant.conf is writable.
  • to be listed...
