v4l applications

12-05-2009, 01:48 PM

There are some old v4l applications that do not work in Fedora 12.

I found so far fmtools and gnomeradio.

Gnomeradio accepts v4l2, but one has to use a gconf editor
to change the driver (there is no option in the application interface).

I tried to patch gnomerario, but I do not know how to force
updating gconf database. I think that a new account should
have the new defaults, but how do I force a change in a previously created account?

Thanks.

I'm the maintainer of gnomeradio, but I haven't used it for a while because
I'm away from my desktop PC, which has an analog tv/radio tuner card.
Would you be interested in co-maintaining gnomeradio?

I'm the maintainer of gnomeradio, but I haven't used it for a while because

I'm away from my desktop PC, which has an analog tv/radio tuner card.

Would you be interested in co-maintaining gnomeradio?

Sure. There are very few radio applications around, and they are kind of unmaintained upstream. I made a review request yesterday with a patched gqradio for working with v4l2.

gnomeradio just needs best defaults for v4l2 and a script for having sound

using sox, because it never recognized the mixer channels of my card:

http://orion.lcg.ufrj.br/RPMS/src/gnomeradio-1.8-4.fc12.src.rpm

kradio4 works fine with v4l2 and fmtools is bkoken.

Thanks.

It would've been easier for me if you had just posted a patch for the specfile
along with the patch you wanted to apply to the source.

Anyway, I had a look at it and I don't like it. You're hardcoding the driver
to v4l2. I think it'd be better to simply make the autodetection try v4l2
first. Also, is it necessary to change "/dev/radio" to "/dev/radio0"?

Please try the attached patch and see if it works for you.

Thanks and regards,
R.

There is no /dev/radio in Fedora 12 any more. Only /dev/radio0.
But this is up to you, because it can be set using the interface.

It worked just fine, and it is much better indeed. This way, the default
can be "any", and it will work with v4l2.

It is also working in Fedora 10 for me.

Thanks.

OK. I think your change can stay, then.

Great! Thanks for testing. I've applied the patch to rawhide. Feel free
to request ACLs and port the changes to F-12/11 yourself. I might be too
busy to do it anytime soon. Could you forward the patch upstream, too?

One more thing: I added your script to the package, but as %doc. I don't
think we should be installing it in %{_bindir} by default.

Regards,
R.

The current fmtools developer, Ben Pfaff, told me he would send me a patch
soon. I will test it and then forward it to you.

Thanks.

The current fmtools developer, Ben Pfaff, told me he would send me a patch
soon. I will test it and then forward it to you.

Well, Ben Pfaff sent me a new version, and I have a src.rpm here:

http://orion.lcg.ufrj.br/RPMS/src/fmtools-2.0-2.fc12.src.rpm

http://orion.lcg.ufrj.br/RPMS/SPECS/fmtools.spec

I also rewrote the spec file for including tkradio, a tcl/tk wrapper for fmtools.

In my case, I need to call

*/usr/bin/v4lctl -c /dev/radio0 volume mute off

to unmute my radio (v4ctl is from xawtv).

I reported this issue to Ben Pfaff, but at least fmtools is up again.

If someone with a different capture card could test this new version,

it would be great.

Thanks.

Hi Paula, and thx for your work,

Have you made a cvs request, so you can commit the spec directly?

Once that said there are few things I dislike in your src.rpm:
- The original source code of fmtools-2.0 doesn't seems present.
(same problem as fmcontrol), but I expect it to be present when the
release will be made official.
- You don't install with -p
- the desktop file could be bundled within the original source code and :
X-Desktop-File-Install-Version=0.15 should only be added by
desktop-file-install on %install
- Requires: tk seems a big dependency for a simple cmd line tool as
fmtools, Can you sub-package tkradio ? (or submit another package for
it ?)
- You haven't keept the changelog from the fedora package, Can you
rebase on it ?

Thx
