Time for a v4l-utils 1.8.0 release

[Gregor Jasny]

Hello,

It's already more than half a year since the last v4l-utils release. Do
you have any pending commits or objections? If no one vetos I'd like to
release this weekend.

Thanks,
Gregor

There is are a additions I'd like to add to v4l-utils: 

1) on DVB, ioctls may fail with -EAGAIN. Some parts of the libdvbv5 don't
handle it well. I made one quick hack for it, but didn't have time to
add a timeout to avoid an endless loop. The patch is simple. I just need
some time to do that;

2) The Media Controller control util (media-ctl) doesn't support DVB.

The patchset adding DVB support on media-ctl is ready, and I'm merging
right now, and matches what's there at Kernel version 4.1-rc1 and upper.

Yet, Laurent and Sakari want to do some changes at the Kernel API, before
setting it into a stone at Kernel v 4.1 release.

This has to happen on the next 4 weeks.

So, I suggest to postpone the release of 1.8.0 until the end of this month.

Regards,
Mauro

I think Hans wants changes too.

We'll try to, but depending on how review goes this might take more time.

In the meantime I suggest moving the media-ctl changes to a separate branch 
and go with the v1.8.0 release as planned.

Hi,

Maybe someone would like to give the v4l-utils a spin on FreeBSD before 
release? Or is this the latest code in the .git ?

I'd like to release v4l-utils 1.8.0 during the upcoming weekend. Please 
postpone any disruptive fixes until the release has been tagged.

Thanks,
Gregor

OK.

There was one patch there adding support for DVB at the Media Controller
part based on the old approach. As we decided to use a different
approach ("MC next generation"), I reverted the change, as we won't
want that change to go to the distros. It is not actually a big deal,
as there's no released Kernel using the old approach, and the code in
question is only triggered by certain types of defines that will never
be found. Yet, I prefer not having an API support on a non-development
branch for something that will never be mainstream.

Besides of such change, I think the remaining stuff there are OK for
a new release.

After the release of 1.8.x, I'll likely be merging a test application
to allow checking the new API on the next development branch, at
contrib/test.
