phonon-backend-gstreamer update to 4.8.2 and qt5 support

[RJVB (René Bertin)]

This patch updates phonon-backend-gstreamer to the current version 4.8.2, and introduces the subport qt5-phonon-backend-gstreamer which builds the code for Qt5 .

Could we make this depend on gstreamer1-gst-plugins-good instead of gstreamer1-gst-plugins-base so there is actual functionality out of the box?

[RJVB (René Bertin)]

That's going to add quite a few dependencies, I see.

Since you appear to know these projects: are we talking about build dependencies or runtime dependencies?

If you are implying that the phonon gstreamer backend needs the "good plugins" in order to serve any purpose (i.e. produce even the simplest of beeps), then yes, it might be useful to pull in those instead of more minimum dependencies. If not and we're talking about runtime dependencies, it should maybe remain an optional addition.

[springermac (Jonathan Springer)]

Yes the phonon-backend-gstreamer port needs the gstreamer1-gst-plugins-good port to be able to play or process any audio or video.

The phonon-backend-gstreamer port would depend only on the gstreamer1-gst-plugins-good port which depends on the gstreamer1-gst-plugins-base port and gstreamer1 port.

[RJVB (René Bertin)]

I just installed port:gstreamer1-gst-plugins-good but the phonon examples still do nothing for me. Should phonon or the gstreamer backend be rebuilt with gstreamer1-gst-plugins-good in place?

Also, gstreamer1-gst-plugins-good depends on more than just gstreamer1-gst-plugins-base and gstreamer1, which was my point.

[RJVB (René Bertin)]

See ​https://trac.macports.org/ticket/46658 . Do you have suggestions how to configure pulseaudio properly, or what other gstreamer plugin to use?

[springermac (Jonathan Springer)]

Could you add this to at least the qt4 variant and the qt5 if you want?

post-destroot {
        file mkdir ${destroot}${qt_plugins_dir}
        copy ${destroot}${prefix}/lib/kde4/plugins/phonon_backend ${destroot}${qt_plugins_dir}
    }

[RJVB (René Bertin)]

I'll have it make a symlink ${qt_plugins_dir}/phonon_backend -> ${prefix}/lib/kde4/plugins/phonon_backend . That's what I have on my end.

But not of the Qt5 version to KDE4. That doesn't make sense, and would most likely cause crashing.

[springermac (Jonathan Springer)]

Sounds good. Thanks.

[springermac (Jonathan Springer)]

The latest diff doesn't have the full changes and fails because ${destroot}${qt_plugins_dir} doesn't exist during destroot.

[springermac (Jonathan Springer)]

Still fails because of the missing directory and it depends on gstreamer base instead of gstreamer good.

Otherwise looks good and works with qt4 (I haven't tried with qt5 yet).

[RJVB (René Bertin)]

This one works for me (yeah, tested it this time...)

[RJVB (René Bertin)]

A full Portfile is always safer O:⁾

[RJVB (René Bertin)]

Oops, my bad. If I'd checked I'd have seen I wasn't diff'ing against the Portfile currently in MacPorts svn ...

[RJVB (René Bertin)]

Aligned the qt5 subport to the "suffix principle".

[mkae (Marko Käning)]

Are there any consequences for this port due to #46552?

[RJVB (René Bertin)]

No. The VLC and GStreamer backends can be installed together, and the multimedia KCM has a sheet to select between the 2. The GStreamer backend requires PulseAudio to work, though, which isn't the most appropriate way to create sound on OS X.

[mkae (Marko Käning)]

OK, so, is this submission sufficiently tested and can be considered safe for committing?

[RJVB (René Bertin)]

I hope so, and think that any potential issues with the Qt5 subport will only come to light once it's been allowed into the wild ...

[mkae (Marko Käning)]

You've got a

replaced_by     ${name}-qt5 

set for port qt5-${name}.

This can be removed from the final portfile, as this was only locally needed on your end, I suppose.

Ports related to Qt5 on MacPorts are as of now:

$ port echo qt5-*
qt5-creator-mac                 
qt5-creator-mac-docs            
qt5-creator-mac-examples        
qt5-mac                         
qt5-mac-docs                    
qt5-mac-mysql56-plugin          
qt5-mac-psql84-plugin           
qt5-mac-sqlite3-plugin

I'll test whether it builds here on my Qt4 and Qt5 VMs and then commit the port. Thanks for taking care of this!

[mkae (Marko Käning)]

OK, I guess, this can be committed as is, even with qt5-mac in its current non-concurrent state, right?

[RJVB (René Bertin)]

I would think so.

[mkae (Marko Käning)]

The patch file PGBS-482.diff isn't applying anymore as is, since the port has been updated to 4.8.2_1 in the meantime. René, can you have created a new portfile diff? (Ping)

[mkae (Marko Käning)]

What's the status of this port, actually?

​I've found that the Qt4 version actually fails because it cannot find GST headers anymore.

I could create a separate ticket for now, if needed...

[RJVB (René Bertin)]

Oops, apparently I missed this or completely forgot about it. Attaching a new diff.

[mkae (Marko Käning)]

Failing build with latest patch

[mkae (Marko Käning)]

Hi Michael, can you take over this one?

That's #50049.

[mkae (Marko Käning)]

I guess I can take over. Assigning it to myself now, please revert, @michaelld, if you feel like it, otherwise I'll take of this in the near future.

[michaelld (Michael Dickens)]

You're on a roll .. don't let me stop you! I have way too many other things requiring my attention right now; I'm just barely able to keep up with my "usual" MacPorts work ...
