Patch LGTM (informally reviewing).

Like you mention, building with all the multimedia support disabled is not
officially supported, but we try to make it work on a best-effort basis
because it can be hugely beneficial for embedded devices which do not
need media playback: not only WebKit is slightly smaller, but all the
disk space taken by GStreamer and friends is saved as well -- last time
I checked this amounted to twenty-something megabytes of disk space
savings for WPE.

Patch was broken (mistakenly using VIDEO_TRACK instead of VIDEO in a few places). This one should work, let's see what the EWS bots say.

Also, please add it in the backports list for 2.22.x:

Thanks!

Building WPE with MiniBrowser enabled and VIDEO/WEB_AUDIO disabled
results in a build failure. The CMake invocation used was:

  % cmake -DPORT=WPE -DCMAKE_BUILD_TYPE=Release \
     -DENABLE_VIDEO=OFF -DENABLE_WEB_AUDIO=OFF -DENABLE_MINIBROWSER=ON

The build fails in the MiniBrowser code with the following error:

[100%] Building CXX object Tools/MiniBrowser/wpe/CMakeFiles/MiniBrowser.dir/main.cpp.o
.../WebKit/Tools/MiniBrowser/wpe/main.cpp:30:10: fatal error: gst/gst.h: No such file or directory
 #include <gst/gst.h>

Hah. This doesn't check the macro values. Can you follow-up, Claudio?

[Philippe Normand]

Ok, nevermind... The issue is in wpe's minibrowser. Forget previous comment :)

[Adrian Perez]

I have a fix already for the WPE MiniBrowser, it's just a
few lines so I will commit it as unreviewed build fix in
a moment =)

Not sure how this couldn't break for you? InspectorInstrumentation::addEventListenersToNodeImpl() calls this method. My !video !web-audio build broke because of that, with a link error. I'll land another follow-up, the ENABLE(VIDEO) should be moved inside the method I think.
