Description Dennis veatch 2019-04-19 11:15:19 UTC 
SUMMARY
ktp-call-ui depends on qt-gstreamer which is no longer maintained per; https://gstreamer.freedesktop.org/modules/ . Unfortunately qt-gstreamer fails to compile for me. Since it is not maintained you might want to think about absorbing it or finding a different method.

STEPS TO REPRODUCE
1. Compile latest version of gstreamer (1.15.x as of now).
2. Compile latest unmaintained versionof qt-gsteamer, it will fail.
3. Unable to compile ktp-call-ui since it depends on qt-gstreamer.

This affects openSUSE now too.

qt-gstreamer is about to be dropped because it fails to build, and that means we will have to drop ktp-call-ui as well.

Patch for qt-gstreamer

Hi folks. I just found out this issue.
Recently I became a KDE Telepathy maintainer and though I'm not active here (I'm busy with the underlying stuff), I'm kindly asking you to keep the project in your repos for a bit longer.

The compilation error is caused by commit https://gitlab.freedesktop.org/gstreamer/gstreamer/commit/b27ee943c2a44a5437a5343d21a9d2be918a1279

This commit introduces a brute C-style cast that prevents a compiler from proper C++ casting. The workaround is trivial:

src/QGst/caps.cpp:57

 void Caps::append(const CapsPtr & caps2)
 {
-    gst_caps_append(object<GstCaps>(), gst_caps_copy(caps2));
+    const GstCaps * caps2ptr = caps2;
+    gst_caps_append(object<GstCaps>(), gst_caps_copy(caps2ptr));
 }

I'll try to reach the last qt-gstreamer maintainer to upstream the fix.

Thanks Alexander, that worked.

I'm afraid that patch won't get accepted in openSUSE though (the immediate response was negative), as the main reason to drop the qt-gstreamer package is that it is officially unmaintained upstream. :-/

(and ktp-call-ui is the only thing using it)

Dear user, unfortunately Telepathy is no longer maintained.

Please migrate to another solution, e.g. for Jabber a possibility is Kaidan, for Matrix a candidate is NeoChat.
