A few days ago I downloaded the latest v4l package from
http://linuxtv.org/repo/, and I've made a few attempts at getting it to work.
Unfortunately, they've all failed, whether I use the firmware provided with
IVTV or the firmware I got as described in my wiki entry. The driver loads
and seems to work via mplayer; however, MythTV creates 0-length files,
returning errors in its log:
2007-03-09 22:49:27.479 MPEGRec(/dev/v4l/video1) Error: Error getting codec
params using old IVTV ioctl
eno: Bad address (14)
2007-03-09 22:49:27.484 MPEGRec(/dev/v4l/video1) Error: Can't open video
device.
eno: Device or resource busy (16)
This is with a 2.6.19.1 kernel. I get the same results with a 2.6.20 kernel
and its standard drivers. If you've had better luck, I'd love to hear the
details.
