This is the way i fixed it.
Step 1: use 'apt-cache search -n gstreamer' to get the list all of the gstreamer and libgstream lib
Step 2: for each of lib in the list. Use 'apt-get install name-of-the-gstreamer-lib' to install it. After install almost the lib in the list my example run. ( i don't know which is the exactly lib i need to install. I just install all of them until my example run)
Step 3: rebuild your example and run.
I suspect @speeter will have long disappeared, as that post was a year ago :)
Just a thought: have a look at (the first part of) https://raspberrypi.stackexchange.com/a/61086, which claims it's a generic Linux problem rather than just a RPi one. It's not quite the same messages, but worth investigating?
@tamolo You used qmake from home/Qt5.7 to build QtMultimedia, right? In this case make install should copy it to home/Qt5.7. If it did not then you still can copy the stuff manually. Actually, if you call "make install" you see what it is installing where.
hi and welcome
Maybe you can try with "Media Player Example" to see if it will load and play file. ?
Its available directly in creator under the examples tab. just type video in search.
It might be it dont like the format.
Got another problem though I have managed to cross compile Qt5 with gstreamer1.0 support it is unable to play HD videos on pi.
I checked using GST_DEBUG=3 and it seems like it still uses gstreamer0.10.
So Do anyone have got HD video playing on pi and can suggest me to get it playing??
