[meta-freescale] video playback failed with "app" user

[Ray·Bloodworth]

Hi, Alexander
    Thanks for you help!

    Video playback is ok now. After adding 'app' user to 'audio' group, audio output is still not working with user "app"...

    Audio stream is routed to pulseaudio sink by media player. 

    Could you give me any advise?


BR,

please check your /etc/udev/rules.d/10-imx.rules file. It must contain
following lines:
 
KERNEL=="mxc_ipu", MODE="0666"
KERNEL=="mxc_vpu", MODE="0666"
SUBSYSTEM=="video", MODE="0660"
KERNEL=="fb[0-9]", MODE="0660", GROUP="video"
KERNEL=="gsl_kmod", MODE="0660", GROUP="video"
KERNEL=="galcore", MODE="0660", GROUP="video"
 
If there no such lines - add them and reboot device. This should fix
access rights to ipu, vpu and gpu devices.
 
Then add 'app' user to 'audio' group - this could be a reason why you
have no sound.
