 |
|
Hello
I am having some problems with ivtv and my Hauppage PVR-250. I have had it working before but never since kernel > 2.6.18
Currently I am using kernel 2.6.22 and ivtv 1.0.1
if I use vlc to open the capture stream or a simple cat from /dev/video0 I get the static from the tv tuner. If I try and select channel 1 for composite in vlc all I get is a black screen, but perfect audio. I have booted into windows to check that in input and wires are all ok using wintv2000 and the picture displays.
gives
| Code: | | /dev/video0: 73.250 MHz |
but I presume this is channel the channel for the tuner as it gives a frequency so -d must change the input but when I try this it always prints out the help again, I have tried
| Code: |
ivtv-tune -d 1
ivtv-tune -d1
ivtv-tune -d=1
ivtv-tune --device=1
|
and also many other numbers but as I said the help just prints out again, so I presume it is not actually changing to composite
The help says the following so I presuming I am using the correct command
Channel/Frequency changer for V4L2 compatible video encoders
| Code: |
Usage: ivtv-tune [OPTIONS]...
-h, --help Print help and exit
-V, --version Print version and exit
-c, --channel=CHANNEL set new channel
-d, --device=DEVICE set video device node
-f, --frequency=FREQ set new frequency (MHz)
-l, --list-channels list all channels and their frequencies
(default=off)
-L, --list-freqtable list all available frequency mappings (default=off)
-t, --freqtable=STRING set frequency map to use
-x, --xawtv=CHANNEL set new channel using custom map from ~/.xawtv
|
Any help would be greatly appeciated

For those interested
a friend of mine found out for me that all the functionality to swap video input (and other functionality) has been moved out of and into
as the part of ivtv has moved into kernel 2.6.22 I can now successfully switch my video in to composite although I won't be able to check if the image is being displayed until I get home, fingers crossed! |

using the command to switch to Composite 3 workd
although I now have picture it has a delay of about 1 - 2 seconds which makes playing games through the card impossible. There is no delay in windows so I presume this is also possible in linux (then I can get rid of windows!), anyone know anything about this?
thanks |
