<div dir="ltr">Hello,<br>
<br>
I have been reading and trying to create a fullscreen multimedia player
for Raspberry Pi 2 (roughly, a screen with play/pause etc. icons on it.)<br>
<br>
So I cross-compiled Qt5.5.1 on latest Rasbian image. Than I tried a
simple media player application on Qt but the attempt was futile. The
video appeared as a series of discrete images(~one image per 5 seconds).
<br>
<br>
After that I find out that QtMultimedia module was lack of use the Pi's
GPU while decoding. So it was doing a software decode for video.<br>
<br>
After some research, I learned that at the build time Qt detects some
libraries that built-on Pi's sysroot and it binds its modules to those.
And Qt recognize gstreamer as QtMultimedia binding. So I guess I had
that problem because of my gstreamer was not doing hardware decode (I
had gstreamer0.10)<br>
<br>
So I have downloaded gstreamer1.0 from official Raspbian repo over a
clean and latest Raspbian image. And started new Qt build but when I
./configure, Qt can not detect gstreamer1.0;<br>
<br>
GStreamer 1.0 auto-detection... ()<br>
Project ERROR: gstreamer-audio-1.0 development package not found<br>
GStreamer 1.0 disabled.<br>
<br>
I found someone who was is made possible Qt to use Pi's GPU(<a href="http://thebugfreeblog.blogspot.com.tr/2015/07/binaries-for-hardware-accelerated-qt.html" target="_blank">http://thebugfreeblog.blogspot.com.t...erated-qt.html</a>). I am trying to implement it but I also as I read some it is also possible to use GPU with QtMultimedia if I have gst-omx?<br>
<br>
I know that subject have some cursed, but is there anyone out there who
has able to use QtMultimedia module with GPU? I would be appriciate to
what are the specific packages that Qt needs and would recognize?<br>
<br>
I thank you,<br>
Sina
