"RaspberryPi2EGLFS" guide question

ben80

Hi,
currently i am using qt5.3 cross-compiled on rpi wheezy.
I would like to upgrade to jezzy and then to qt5.5.1 or qt5.6.

There is a new guide, which claims to enable hw accelerated opengl: http://wiki.qt.io/RaspberryPi2EGLFS

Does this include playing hw accelerated videos through qtmultimedia?
If yes, how does that work? I thought it requires gstreamer 1.x which is not included in the "configure" command
There were a few posts, that reported on qt5.5.0, that gstreamer1.0 doesn't work with the egfls plugin. Those posts are a few month old, though. Has this been fixed, or is it still not possible?

Thanks a lot for your help,
Ben

Hi. I'm using Debian 8 (jessie), by upgrading my Raspberry Pi from Debian 7 and Qt 5.5.1.
I confirm that Qml and OpenGL ES does not work.
I'll try Qt 5.1.1 during the weekend with the official Debian Jessie iso.
If you will be able to run a Qml application in Raspberry please write here.
I'm very interested because if there isn't a solution I have to downgrade two Qml applications to QtWidgets

My question was about hw accelerated movies using qtmultimedia.
I compiled qt 5.3 a while ago for rpi 1 and that works like a charm.
I am using qml and that's run hw accelerated on the pi.

Ah, ok.
After following the guide still I can't use qml, I obtain the generic error "not find platform plugin eglfs" but it is list after.
Can you explain how to start a qml application? Are you using xorg as container or simply something link ./App -platform eglfs??

Hm, can't remember how i did it at the beginning.
Right now, i am compyling and deploying my apps fro qtcreator on my host linux pc. After that i can simply run the apps on the pi by ./myApp -> without the platform option

mrdebug

Ok. Are you able to run Qml applications in Raspberry Pi?

@ben80 There is now a section about Qt Multimedia on the page. It is not quite reliable for now, unfortunately.

To have qtmultimedia (hw decode) use this : http://thebugfreeblog.blogspot.fr/ , it works like a charm !!!
