I cry every time I see samba during updating my profile, so I wonder if
it is acceptable to have "mpv-minimal" which is less heavy on
dependencies.  If so, perhaps the other people have ideas what inputs
may also be removed, thanks.

Or would it make sense to remove samba altogether from the regular mpv
package?

As an mpv user and the one who initially packaged it and added samba
(because I simply added all optional dependencies), I don't mind.

I'm personally for it, but there may be users who need mpv with samba
support, so I'm not sure if it is right.  I thought that default Guix
packages should be full-featured, no?

we could rename the current one mpv-network-support or something similar.

No idea. I am not sure we need windows support :-)  (or whatever this is
exactly). If nobody needs it and some feel disturbed, we may as well
remove it for the time being and think again once someone requests it.

Rather not; the default package should have the default name.

I agree!

I am an mpv user and I would really like to get rid of this samba
output, as it is heavy-weight and IIUC the lost functionality would be
an impossibility to play audio/video files from remote resources
connected using samba (which most likely are "MS Windows" partitions).

So if other people do not object, I'm going to remove 'samba' output
from 'mpv' package.

I suggest making it a separate output so that users can get the
functionality if they need but the default package does not include it.

I can try it in the next couple of days — I've been meaning to learn how
to create multiple outputs for a package.

I also use samba for my networking around my place. My wife needs windows for
her work, so I have our RPi/NAS set up to use samba instead of nfs.

I don't see how it can be done using a separate output (but I don't know
much about multiple outputs as well :-)).

But do you need mpv built with samba support?  This thread is not about
samba package, but about removing samba output from 'mpv' package.  BTW
I don't insist on it, originally I suggested¹ to add 'mpv-minimal'
package, and I would be really happy with it rather then removing
functionality from 'mpv' package.

I don't know if this will top post but hopefully not.

I looked at the MPV github page and the syntax for MPV over built-in samba is 'mpv smb://user:password@host:/full/path/to/file.ext' and without tab completion and without support for .netrc or .smb.conf I would never do that. Once the directory is mounted locally it doesn't need samba to play networked content.

Now that I've looked at it more it seems samba support isn't really a useful feature for mpv.

One build and two outputs, mpv and mpv-minimal, would be nice for a
substitution server but not be too helpful in the case of building your own
packages. I don't believe it would be possible.

off the top of my head for defining mpv-minimal in terms of mpv (see
python.scm for a lot more examples):

(define-public mpv-minimal
  (package (inherit mpv)
    (name "mpv-minimal)
    (inputs (alist-delete "samba" (package-inputs mpv)))))

I think Alex and Efraim are right, based on my very limited
understanding of multi-output packages.

Since I don't use mpv or samba, I don't have a stake in this. Feel free
to do whatever you decide.

Great news, thanks for looking at it!  Now this looks like a
not-very-common feature indeed.  I'll wait for other objections for a
week or so before removing 'samba' input from 'mpv' package (although I
would still prefer to have an 'mpv-minimal' package).

Either way (removing Samba from MPV’s dependencies, or adding an
‘mpv-minimal’ package) is fine with me.

Done in commit fbbaa4d.  Let's see if anyone will report about missing
feature :-)
