    @jsulm Yes if I run command "/etc/init.d/musicplayer.sh" the application work as per expectation. About library, not conformed but seems like gstreamer library cannot be initialised.

      @Omkareshwar Does your device have an UI? If so, maybe you should start your app when the UI is initialised?

          Hi,

          Do you have an X server running ?
          At what level are you starting your application ?

            @SGaist No I am using wayland. I have placed my script at "/etc/init.d/musicplayer.sh" and created a link for file at "/etc/rc3.d/S95musicplayer.sh".

              Then are you sure that wayland is started before your application ?

                @SGaist No we use to stop the weston server before starting the application and application is launched by platform EGLFS using eglfs plugins (KMS/DRM).

                  @Omkareshwar said in could not initialize supporting library:

                  @SGaist No I am using wayland. I have placed my script at "/etc/init.d/musicplayer.sh" and created a link for file at "/etc/rc3.d/S95musicplayer.sh".

                  These two statements look contradictory. So what exactly are you doing with your device ?

                    @SGaist file system is for wayland, but we have compiled plugin for eglfs and we are using that plugin for qt application platform, without westorn server. It is launching via eglfs, and to start application on bootup we have created a script which will launch the application with eglfs platform. Now problem is when we mount USB and play music via it error comes , and if we launch application via directly script it works perfect

                      Hello everyone,
                      I got solution for this issue. I got dump for environment variable from application. They were different in both case(on boot-up and from terminal). I just exported that variables in my script and output was as per exception. Thank you every one for support and valuable time.
