Help. About QMediaPlayer performance
-
I am a qt5 newbie (a qt newbie actually). I took a QMediaPlayer example from internet, built it and ran, and it really decoded a H264 1080p video sample in my PC. But its performance is not good and it consumes too much CPU power--over 120%. Ah..Intel(R) Core(TM) i3-3220 CPU @ 3.30GHz is the CPU in my PC and ubuntu 13.10 is the operating system.
I guess I could improve the performance in two ways. First, I do the video decoding/rendering part using other libraries/APIs myself, such as using libav/vaapi/xvideo extension. Second, try to "improve" the mediaservice plugin and its dependent libraries(gstreamer related). Now I prefer the second way. Any opinions would be appreciated. Thank you very much.

Hey,
Have a look at
http://projects.tano.si/vlc-qtit's a really good video player (VLC) that can be embedded in a Widget.
Not too hard to set up, work the same on all machine and I get good performanceGood luck
