Description Daiane 2012-12-12 16:34:36 UTC

I did find an issue with qmediaplayer on i.MX6 though. It appears that a
reference to /dev/video17 leaks during each video playback.

Before playing any videos, no handles are open:

~# ls -l /proc/`pidof qmediaplayer`/fd | grep /dev/video
~#

During the first video, two handles are open:

~# ls -l /proc/`pidof qmediaplayer`/fd | grep /dev/video
lrwx------    1 root     root            64 Dec  9 23:49 16 -> /dev/video17
lrwx------    1 root     root            64 Dec  9 23:49 17 -> /dev/video17


If I let the first complete, then open another video, I see
three handles:

~# ls -l /proc/`pidof qmediaplayer`/fd | grep /dev/video
lrwx------    1 root     root            64 Dec  9 23:49 16 -> /dev/video17
lrwx------    1 root     root            64 Dec  9 23:49 17 -> /dev/video17
lrwx------    1 root     root            64 Dec  9 23:52 18 -> /dev/video17

and so on.

I caught this after repeatedly playing the very short akiyo.mp4
from /unit_tests. After a few successful runs, video playback
stopped.

I was able to reproduced it under a imx6qmachine. I wonder if this problem has to be solved under the meta-fsl-arm or we simple have to report it to the right community. Checking on google for possible solutions...

    imx-test: Condition the mxc_epdc_x11_fb_test installation
    
    Condition the compilation/installation of the unit test
    '/unit_tests/mxc_epdc_x11_fb_test'.
    
    This binary is only valid on specific platforms (not yet supported by
    current layer) like IMX508.
    
    Tested on a Sabre SD i.MX6Q board. Fixes:

    qt4: Add a unreference instruction on qt4 phonon patch
    
    Correct the qt4 phonon patch adding a statement which unreferences
    an object representing the freescale video sink. Tested on a iMX6Q
    machine using the fsl-image-gui image.
