@jsulm I don't realy know what this means:

"Unfortunately the GStreamer-based multimedia stuff is not quite usable at the time of writing - accelerated video works only sometimes (and with glitches), while the camera is just broken."
What do you think about this? Is it a good idea to use QtMultimedia or is there a better way to play video on a Qt application with something like libvlc?
Sorry for double-post, it semmed that I haven'nt installed pkg-config on my VM...
Now it seems to be configured properly:
Qt Multimedia: ALSA ................................... yes GStreamer 1.0 .......................... yes GStreamer 0.10 ......................... no Video for Linux ........................ yes OpenAL ................................. yes PulseAudio ............................. yes Resource Policy (libresourceqt5) ....... no Windows Audio Services ................. no DirectShow ............................. no Windows Media Foundation ............... noThanks for your help !
You saved my life !

Were you finally able to cross-compile Qt Multimedia with GStreamer support? If so please don't forget to mark your post as such. Thanks

Hi Matio,
Can you play videos using Qt Multimedia with no problem? Because I didn't, it plays videos but a problematic way. I have raspberry pi 3 b+ and I use qt vlc library to work around this problem. -

I have not tested it for now, I just managed to compile. It took a few hours...
But your comment seems to sadly confirm what I read here (last section of the page):The issue seems to be relative to GStream and not solved yet.
I'll try as soon as possible and keep you informed about this.

Finaly, I can't even play videos. I can only play sounds.
When I compile and execute I have this mesasge:
CRITICAL **: gst_video_decoder_set_latency: assertion 'GST_CLOCK_TIME_IS_VALID (min_latency)' failed
So I will use libvlc unless you know what this error means.

Hi, sorry for the late answer.
I had issues installing vlc-qt, but suceededly install libvlc and it was what I needed finaly.
I'm still interested in vlc-qt if you can help me.
I'm using RaspberryPi 3B+

@matio
Hi, I didn't install vlc-qt , I installed vlc and compiled vlc-qt library. My project is not qml based. I am using a widget-based qt app and at this time I am successful.I can try to help you as much as I can.

Hi!
Thank you for your help.I followed the instructions of this page:
https://github.com/vlc-qt/vlc-qt/blob/master/BUILDING.md
But during the make step, at 93% of the compilation I have an error:

I compiled vlc-qt on raspbian os. Also don't use "make -j8" command just use "make" or may be "make -j4"
I compiled it on raspbian too and I haven't used the -j option.
I tried again today but I still have the same error.
The issue is surely related to this message:
"the version Qt_5 not defined in file libQt5Core.so.5"
But I don't know what this means and how to solve it.
