Error: "Your GStreamer installation is missing a plug-in."

I am using –
Embedded Device(SOC) – Colibri-T20 (NVIDIA,Toradex)
Os - Angstrom v2017.12 – Kernel
Colibri-T20_Qt5-X11-Image 2.8b6 20190816

Which package I am missing in my os
If am running this application on my Linux Desktop and imax6 it works correctly .

hi @bhupendra

I don’t think that an application running on iMX6 will run on T20 without any adaptation.

Could you share some information about your application and provide a sample code?

Best regards,

hi @jaski.tx
please find my attached source code…link text

hi @bhupendra

Thanks for the files. We will look into them and come back to you within this week.

Thanks and best regards,

Hi @bhupendra

I am sorry but I did not have time to look into this issue till now. I will start to work on this Ticket tomorrow.

Thanks for your patience.

Best regards,

Dear @bhupendra,

Thank you for your patience.

We are not able to reproduce the issue. Could you share which Qt version you are using? If possible, please share the executable application with us? Could you run this application on your device and let us know the output.

Could you set below configuration in MyCamera.Pro file and try to test


By executing the following commands I can able to see rtsp streaming on the Colibri T20 module, let us know if you are getting similar behavior?

  • opkg update
  • opkg install gst-plugins-good-rtsp
  • gst-launch rtspsrc location=“rtsp://” ! rtph264depay ! nv_omx_h264dec ! nv_gl_eglimagesink
