GStreamer feature

[SGaist]

Hi,

Did you install the GStreamer development package ?

[MichalF]

Hello and thank you for response!
yes, I did.
here you can see:

$ dpkg -l | grep libgstreamer1.0-dev

ii libgstreamer1.0-dev:amd64 1.14.4-1 amd64 GStreamer core development files
ii libgstreamer1.0-dev:armhf 1.14.4-1 armhf GStreamer core development files

$ dpkg -l | grep libgstreamer-plugins-base1.0-dev

ii libgstreamer-plugins-base1.0-dev:amd64 1.14.4-2+deb10u2 amd64 GStreamer development files for libraries from the "base" set
ii libgstreamer-plugins-base1.0-dev:armhf 1.14.4-2+deb10u2 armhf GStreamer development files for libraries from the "base" set

also the headers files:

$ ls /usr/include/gstreamer-1.0/gst/gst.h

/usr/include/gstreamer-1.0/gst/gst.h

$ ls /usr/include/gstreamer-1.0/gst/gstplugin.h

/usr/include/gstreamer-1.0/gst/gstplugin.h

Then check in the configuration logs what exactly made the detection fail.

@SGaist Hi,
It looks like when I configure it, there are some errors, like:

fatal error: AL/al.h: No such file or directory
#include <AL/al.h>
^~~~~~~~~
compilation terminated.

But I do have AL installed.
Also:
fatal error: alsa/asoundlib.h: No such file or directory
#include <alsa/asoundlib.h>
^~~~~~~~~~~~~~~~~~
compilation terminated.

fatal error: assimp/cimport.h: No such file or directory
#include <assimp/cimport.h>
^~~~~~~~~~~~~~~~~~
compilation terminated.

Could these errors affect gstreamer?

thanks

This is the error of interest.

Did you nuke the build folder after installing the dev packages and before calling configure ?

@SGaist Hi
I have build it before, but now I want to add the multimedia support, so I try to reconfigure it and then do make again.

[SGaist]

Ok, what I would do is to build the Qt Multimedia module independently, in a different folder, no need to rebuild the whole of Qt.

@SGaist said in GStreamer feature:

How can I do that?

[SGaist]

The same way you would build a classic CMake based project. You can use the qt-cmake wrapper to help set things up.
