Shouldn't we default to gstreamer 1.0 when both are enabled?

I'm sorry, but I don't think this is really the source of the problem.
I did reproduce this build failure, and even if GStreamer is built
before Qt5 (which is the case in the build failure you're linking in
the commit log), Qt5 concludes that GStreamer is not available.

And this is because for some reason, Qt5 now seems to ignore the
PKG_CONFIG environment variable that we pass to it. I've added some
debugging messages to the packagesExist() function, and it uses just
"pkg-config" (i.e the system pkg-config, not the one built and
installed by Buildroot in $(HOST_DIR)/usr/bin).

While I think that your patch should be applied (it's good to make
optional dependencies explicit), I also think the pkg-config problem
should be investigated and fixed.

Best regards,

Thomas

I have just been testing 2015.08 and have immediately hit exactly the 
same issue. I have done some digging into qt5 and I think I see the 
issue. The problem is that qmake never looks at environment variables, 
only things passed on the command line. The patch below fixes the issue 
for me by explicitly passing PKG_CONFIG on the command line. What is 
unclear is why I am suddenly seeing the issue in 5.5.0 but not 5.4.1 as 
that bit of code seems the same in both versions.

I'll report the issue upstream and see what they say.

Should I spin this into a patch?

I also do not understand why this bug has shows up suddenly...

I already report a bug on Qt bug-tracking system[1]. Feel free to reply 
to it with your investigation

Sure you should spin thin into a patch for Buildroot and for Qt mainline.

As Thomas said, this does not really fix that issue.

However, still following Thomas comment, I think this is a valid patch,
and it should be applied with a tweaked commit log;

    package/qt5base: add support for optional gstreamer

    qt5base can optionally support gstreamer-0.10 or gstreamer-1.0.
    Upstreamer still considers gstreamer-0.10 to be preferred over 1.0.

    Ensure that gstreamer, when enabled, is built before qt5base; tell
    qt5base to use the proper gstreamer variant, or none if gstreamer
    is not enabled.

With that fixed, you can add my:

Peter already patch gstreamer for qt5base and he have removed 
gstreamer0.1 support[1]. I'm not sure this was the good solution because 
gstreamer0.1 is still the default choise for Qt[2] but no buildroot user 
seems to complain about that.

As I explained in the commit message, the reason for disabling the
gstreamer 0.10.x support was that it was broken in qt5multimedia. If
this is (or gets in the future) fixed, then I have no problem adding it
again.

With that said, we should use prefer gstreamer 1.x support over 0.10.x
if both are enabled.

Given the feedback in this thread, I'm marking this patch as rejected in
Patchwork:
  - we already have support for gstreamer-1.x
  - gstreamer-0.10.x seems to be broken.

Thanks for spawning the discussion with your patch! :-)

For now qt recommend to keep gstreamer 0.1 as d?faut version[1].
