Here more informations:
I have tried all the possibilities while running "cat /dev/video0"
- ivtv-tune -c with current/any other channel
- ivtv-tune -c while the input is set on composite/S-Video
(input=0/6) or tuner (input=4)
with the same result in all cases:
/dev/video0 stops sending data...
But:
- /dev/video16 is never affected. For example cat /tmp/video.mpg >
/dev/video16 always works.
Maybe some interesting findings:
ivtvctl --set-input=xyz (can be any input)
cat /dev/video0 > /dev/video16 &
ivtv-tune -c 40
/dev/video0: 319.250 MHz (Signal Detected)
--- no more data from /dev/video0 ---
kill %1 (kill /dev/video0 > /dev/video16...)
ivtvctl --passthrough=1
--- Get the audio but a frozen image from input xyz (probably the first
frame...)...
ivtvctl --passthrough=0
ivtvctl --set-input=0 (my dv cam)
ivtvctl --passthrough=1
--- Get the audio but a frozen image from input=0 (again... probably the
first frame...)...
ivtvctl --set-input=4 (tuner)
--- Get the audio from input=4 but no change to the frozen image.. still
the one of input=0...
ivtvctl --passthrough=0
ivtvctl --passthrough=1
--- Get the audio from input=4 and a frozen image from input=4 (first
frame...)...
So after /dev/video0 stops sending data, in --passthrough mode at on,
the audio works for all inputs but the video is stalled.
Hope it helps.. and don't hesitate to ask if you need more
information... I will do my best...
