Hallo, when I have understood some postings correct, you can use v4l-conf befor starting up an application to get rid of the green-screen problem. Is this right? I could not manage this. I have a 2.4.20 kernel, v4l patches from 7. February and saa7134 from 18. February + xawtv 3.85. With the v4l-conf from the xawtv version I get the following error: map: vt03 => fb0 v4l-conf: using framebuffer device /dev/fb0 mode: 640x480, depth=8, bpp=8, bpl=640, base=0xc8000000 /dev/video0 [v4l2]: ioctl VIDIOC_S_FBUF: Invalid argument The device still does not work after this. Thank you for any help. P.S.: Beside of this transcode works (in a reduced resolution e.g. 384x288)
