Thanks for the response.
I have to say it all sounds like chinese to me.
The switches are all different and I don't have a version of itvtvctl to
compare the switches with.
Would anyone help me be able to map:
ivtvctl -u 0x3000 ==> v4l2-ctl -?
- Looks like it might be:
- v4l2-ctl --set-codec-params=0x3000
- But I really don't know why I would be setting this.
This is just an older analog Samsung video camera. I usually attach it to
me VCR and choose Line1. Never really had to bother otherwise.
ivtvctl -p # ==> v4l2-ctl -?
- Hmm, might be:
- v4l2-ctl --set-input=<num>, but how do you decide what # to use.
/dev/video /dev/video1 /dev/video25 /dev/video33
/dev/video0 /dev/video24 /dev/video32
I have tried capturing from all devices and only 0,1 have video (tuner data)
ivtvctl -f width=720,height=480 ==> v4l2-ctl -?
- v4l2-ctl --set-format=width=<720>,height=<480>
