Setup Hauppauge WinTV PVR-350

Hi all,

I had said card in my mythtv box working flawlessly.

Now I have a digital card in mythtv I am trying to use the PVR-350 on my desktop.

I just want to capture S-VIDEO in, which seems to equal the /dev/video1 device. I do not have this.

You can use the v4l2-ctl tools to change the input selection.
http://www.ivtvdriver.org/index.php/V4l2-ctl

/dev/video0 is the multiplexed stream (audio+video), /dev/video16 /dev/video24 /dev/video32 /dev/video48 are each different things, VBI, raw YUV input, raw PCM input, sometimes other things, depending on the card's capabilities.
[edit]
if you read the code block you posted, it explains what the video24/32... are for on your card

[/edit]

1st tuner = /dev/video0
2nd tuner = /dev/video1
3rd tuner = /dev/video2
----
12th tuner = /dev/video11

With the PVR 150/250/350 the tuner, S-Video (1,2) and Composite (1,2) inputs are all accessed through one multiplexed stream. Since these cards can not receive more than one signal at a time, it only creates a single /dev/video# device. With the PVR 500 (dual tuners) that can receive 2 streams at one time you have /dev/video0 and /dev/video1. With the hybrid tuners (HVR1600) you get a /dev/video0 (analog inputs) and /dev/dvb/adapter0/frontend0, the next digital card would be /dev/dvb/adapter1/frontend0. If the digital tuner had 2 digital inputs (or a single multiplexed tuner) they would be /dev/dvb/adapter0/frontend0 and frontend1.

Each of those devices would in turn, also have their own /dev/video* for VBI, YUV, and PCM.

Oh thank you so much disturbed :0

It was right under my nose the whole time; I did find v4l2-ctl but never found these options.

Thanks alot.

PS So it defaults back to input 0 after reboot?
Must be a way to set it on reboot. Maybe an rc file of some sort.

Thanks again!

Thanks disturbed1 I have an idea on the the sys-v and bsd style boot methods, I think I didn't word my question well.

I was thinking more along the lines of:
~/.ivtvrc
Type of setup.

But my searching shows nothing of the sort.
On well I'll have to use rc.local or put it in my capture script.

Here's another one, I was looking at all the other options with v4l2-ctl and then /dev/video0 stopped producing anything.
So rmmod and modprobe the ivtv module which normally works and now when I try to change inputs /dev/video0 produces nothing.

I read the PVR-350 gets hots, so gave it last night to cool and tried again this morning but same result.
Ever experienced this?
I haven't rebooted so that is still to try.

This is frustrating.

Thanks.

All working now.
One must have a video signal sent on the S-Video channel in order for it to capture anything. Unlike the tuner where its always grabbing a signal, S-Video only grabs signal when you are playing a tape in the VHS hooked up to it, for example. It does capture after the tape stops for a bit, but then captures nothing, so that confused me.

So the script I run, currently, so setup ivtv before I capture is:

No worries disturbed1
I am glad I could repay your tremendous help a little bit.

Once I get this S-video cable, picture quality issue resolved [got a thread over in capturing forum] then I am back to converting VHS tapes which I have been doing for years but with analog cards.

Thanks once again!
