To see if PVR-350 playback works for me yet (didn't two years ago), I
decided
to wipe out and redo a myth box. I'm using FC4 and Jarod's always-useful
howto.
Things were generally good. Modules (including ivtv-fb) installed and
loaded
okay.
Works great:
modprobe saa7127 test_image=1
Works great, good data:
cat /dev/video0 > test.mpg
Trouble:
ivtvfbctl /dev/fb1 --globalalpha=off --localalpha=on
IVTVFB_IOCTL_GET_STATE failed (error: Invalid argument)
I discovered the new argument syntax, but anything I do with ivtvfbctl
returns IVTVFB_IOCTL_GET_STATE failed (error: Invalid argument) So first thing
I double-check is my fb device. It is indeed, as shown below, /dev/fb1 UH oh,
there goes my easy answer. Am I missing something else simple about ivtv-fb?
I should note that I got further than this two years ago, so hardware
shouldn't be the issue. I was always able to change fb settings through the
utilities, and displav X through the 350, it just bombed out after playing
video a bit.
