Thanks!

As far as I can tell, this change doesn't affect the peek
package's output at all. Am I mistaken? What should the
observable difference be, beyond ‘working’?

How are you invoking both peeks, and testing the difference? Are
they both running in the exact same environment, back-to-back?

Kind regards,

It was complaining on Ubuntu when I started it that either ffmpeg needs
to be installed or a gnome-shell needs to be running. I didn't log the
exact error message but that was more or less it.

When I add ffmpeg it worked without the warning and actually started
recording my screen as expected. After pressing the record button of
course ;()

I tested once without ffmpeg and once with ffmpeg.

The former failed to record.

Yup I tested both in Ubuntu.

Let me know if you'd like any more info or if I wasn't precise enough
in my description.

I don't think this will be enough; does the program call the ``ffmpeg''
executable? If so, you'll need to patch the call to ``ffmpeg'' to point to
/gnu/store/.../bin/ffmpeg directly.

Could you also update the inputs/arguments style to gexp form?

And how does this patch provide ffmpeg? It adds it to the build
environment, but what happens then?

We know it doesn't add a reference to the final ‘peek’ output (you
can verify this yourself, assuming peek builds reproducibly). It
doesn't change any code in the peek binary.

So what's the mechanism by which it would work? It will need to
be documented.

But how exactly? Please provide exact steps and commands.

…but in a separate patch, please.)

Hi Tobias,

peek, needs either ffmpeg or gnome shell to be present.

See here for the exact reference:


How should I handle that in Guix?

Should I patch ffmpeg? What if a user wants to use gnome-shell instead of ffmpeg?

Is there a switch I can provide in Guile code?

all best,

jgart

Peek needs to be propagated. An issue is open,

IIRC, peek needs to be patched to avoid the propagation and personally,
I am using something along,

guix shell peek \
gtk+ gsettings-desktop-schemas ffmpeg \
-- peek


Cheers,

I read through the open issue. Should I send a patch implementing lilyp's suggestion?

That's what I was also thinking of doing but I also had the question
regarding choosing between ffmpeg or gnome-shell. Should we prefer
ffmpeg? Would be cool if we could support choosing between ffmpeg or
gnome-shell.

Is there currently a way to do that?

Hi jgart,

The patch you sent does nothing and didn't fix your foreign
distro. The questions you won't answer were supposed to find out
what might have, but let's move on.

So, please test ('s suggestion. It's the right fix! Propagation
isn't.

You can offer two variants of peek (peek-ffmpeg and
peek-gnome-shell, say) if you like. I don't think that's
necessary, though, unless ffmpeg support is incomplete?

Thanks,

T G-R

Ideally: let peek pop up the window asking the user to install
ffmpeg.

Then the user installs ffmpeg only if it's actually needed, and
isn't ‘forced’ to pay the cost if it's not.

Does it not show that window on a foreign distribution?

Kind regards,

Yup, it does show that window on a foreign distro.

So, we should just have the user install ffmpeg along with peek in their profile?

Should this ticket be closed then? https://issues.guix.gnu.org/issue/51202#3

Well, from my point of view, let start to use ffmeg without the
propagation. Then, incremental improvements. :-)

Ok, should I send a new patch patching the ffmpeg executable from the
inputs of peek?

Yes, I think it's expected to install ffmpeg yourself for peek when not
in gnome shell. Close now.
