[Solved]QML Video Accelaration

[hpollak]

Hy!

I like to play more Videos in my QML2-Application on Linux 64 bit.
I'm using 5.1.0 Beta but I allso tried QT 5.0.1

As far i kno QML uses the GStreamer.

It seams the Video-Component does not use the VAAPI.
I try to play 6 Videos at the same time ( no problem wirh vlc on my computer ).

But in my application the Video doesn't real play and the CPU is nearly 95% on all cores.

My Enviroment:

QT 5.1.0Beta
Opensuse 12.3
GStreamer 0.10 & 1.0
Gstreamer VAAPI - Plugin

vainfo found the init function of the fglrx_drv_video
and supports H264 profile

I use the MediaPlayer and the VideoOutput Component as shown in the samples.

Is there any Propertie to set which anables HW-Accalaration?

Now I have seen there is allready a bug-report about this topic:

"QtMultimedia 5.0.0: Missing video frames while playing mp4 video using sample QtMultimedia application":https://bugreports.qt-project.org/browse/QTBUG-30328

It seams like this is the same problem that i have.

I installed kubunt instead of OpenSuse now it works, but i think it is no matter of the distribution. I think the problem was that GStreamer VAAPI plugin ob opensuse was only available for GSTreamer 0.10 and not for 1.0 but my QML-Program was using GStreamer 1.0.
