Hi Guys,
The attachments here are sent using tinypic.com. It's the first time
I've used it, so I hope it works OK.
I'm using the qv4l utility, but I did try it on v4l2-ctl and gst-launch
and the results are the same as the one's I shall post here.
Firstly, here is stk1160 s-video for a baseline comparison. Look at the
word "File" in the file menu:
- http://tinypic.com/m/i50k8z/2
Now here is ImpactVCB-e composite. Again look at the word "File" in the
file menu:
- http://tinypic.com/m/i50k8n/2
The quality is a little worse, but maybe that is just
Composite/S-Video. Composite is not working on my stk1160, so I can't
do a direct comparison.
Now let's look at ImpactVCB-e s-video:
- http://tinypic.com/m/i50k8w/2
It looks like every other line is missing. I'd guess it's 640x240. I've
tried v4l2-ctl -v width=640,height=480 etc, but no difference.
You can see it too with images but it's just not so obvious as with text.
Now when I switch back to ImpactVCB-e composite, I get the same problem,
but after a restart it goes away.
What do you think?
Regards
Stev
