Pete and anybody else out there with go7007 devices, what do you use for capture?
Without GO7007 ioctls, I was only able to get vlc to capture in MJPEG format.

Never actually used one myself, but MythTV has support for at least
the Plextor ConvertX go7007-based devices.

jelle, that you?
Here's the patch against go7007 driver in 2.6.32 kernel (run with -p1).
The main purpose of the patch is to include support for ADS Tech DVD Xpress DX2
usb capture card and make it usable with v4l2-ctl utility.
I also did a general clean-up in a few areas and *temporarily* added back in
proprietary go7007 ioctls, so current mythtv users can take advantage of it and
to make the gorecord program from wis-go7007 package now work again.
Also attached is a stripped down version of gorecord from which I removed all
parameter-setting stuff. This version is meant to be used in conjunction with
v4l2-ctl or other means of configuring capture parameters.
I will try to do mythtv patches next so that it starts using standard v4l2 ioctl
calls and we can drop all proprietary stuff in the driver.
Please try it and lemme know if it works for you. I've run into a few Ubuntuers
as well who were trying to get their boards working as well.

Does VLC try to change video parameters after starting the stream? The
driver currently doesn't allow that. I think I've seen xawtv try to do
that too.

Also, you shouldn't re-add the proprietary API but, instead, to port it to use the
API support for compressed stuff.

I haven't messed with it much, but I think it just uses default driver settings.
When I went to Advanced settings in vlc and tried to change some stuff, it
didn't work at all. I ended up just hacking up gorecord from the original driver
package and got it working that way.
I would probably be worthwhile getting vlc to work with go7007. What do you think?

Mauro, brother, this patch is for in-kernel go7007 driver. It has to be run
against kernel source 2.6.32. (IIRC it will also run against 2.6.31)
It won't run against current v4l-dvb tree, as Pete has done quite a few changes
since then. When I get a chance, I will start working against current version.

I did add support for standard vidioc_s/g_ext_ctrls API stuff and that's what I
am actually using currently. I merely kept the proprietary ioctls so that mythtv
users can start using the driver as well until somebody (me?) patches mythtv to
use the standard APIs. -TJ

It should be against -hg or linux-next tree, otherwise, I can't send it upstream.
If you just want to send a patch for people to test, please mark it as RFC, otherwise
I'll assume that you're sending a patch for upstream.
Since there are more people working on this driver, the better is to add what you
have there, to avoid people to do a similar work.

Ah, ok :)

Ok. While it is still at -staging, we can keep the proprietary ioctls, but they
need to be removed before moving to the right place.

OK my brother. I got a hold of the -hg tree and started working off of it.
Pete, Question: I was looking through the code and noticed that you turned s2250
driver into v4l2_subdev and go7007 driver initializes it as such and passes it
calls via call_all (v4l2_device_call_until_err). How does that affect other
drivers? Does that mean they all need to re-written as v4l2_subdev?

That is correct. The other drivers do not work until they are all
converted to the subdev interface. I'm working on the other drivers
now. I've finished ov7640 and have started on saa7113.
Once the subdev driver conversions are completed, we should be able to
move the go7007 driver out of staging.

Cool man. I will start working on tw9903 and tw9906, as this is my main area of
interest. Is there a template for subdev driver or should I just use your s2250
as an example? -TJ
