Hi all, just few weeks ago I made a patch for the uvcvideo driver in order to flip webcam images. I thought it wasn't possible to ask the webcam to flip the image by itself!!
But now, surfing on internet I found this: http://serialize.blogspot.com/2008/02/asus-g1s-a1-13m-pixel-webcam-adventure.html I have the same webcam described in that post: 174f:5a35 , Sonix Technology Co., Ltd. , USB 2.0 Camera So now I know my webcam can flip the image just changing one bit in a register: 1E MVFP 00 RW Mirror / Vertical Flip Enable Bit[7:6] Reserved Bit[5] Mirror 0: Normal Image 1: Mirror Image Bit[4] Vertical Flip 0: Vertical Flip Disable 1: Vertical Flip Enable Bit[3:0] Reserved You can download here<http://rapidshare.com/files/94672360/OV9655-datasheet.pdf.html>the datasheet of my webcam chip: http://rapidshare.com/files/94672360/OV9655-datasheet.pdf.html Do someone have any ideas on how to change the 4th bit of the register at the address 1E? In the datasheet there is also written that: "The device slave addresses are 60 for write and 61 for read." Any suggestion will be surely useful!!! Thank you very much!! Marco Argiolas
