Hello. I working with StereoLabs ZED 2i camera, install all packages and its indicated by StereoLabs Diagnostic Tools as “ALL OK”.
But software doesnt work.
I see problems with Driver or Dual GPU configuration.
I have Dell Vostro laptop with intel GPU from 11th Gen Intel® Core™ i7-1165G7 and NVIDIA GeForce MX330.
I select Nvidia as a prime and get in system screen:
Graphics: NVIDIA Corporation GP108M [GeForce MX330] / NVIDIA GeForce MX330
Before i have select prime Nvidia it was:
Graphics: NVIDIA Corporation GP108M [GeForce MX330] / Intel Graphics …
Checking in terminal now:
$ lspci -k | grep -A 2 -i “VGA”
0000:00:02.0 VGA compatible controller: Intel Corporation Device 9a49 (rev 01)
DeviceName: Onboard - Video
Subsystem: Dell Device 0a03
$ prime-select query
nvidia

Yes, i testing SVO playback, which no need camera connected. But i get problems with GPU drivers in Ubuntu 20.04 now and Ubuntu 18.04 previously (it was “Started user manager uid 121” stucks, i solved this problem by “nomodeset” start and installation 470 driver manually, but it still worked with errors). Now target version is 20.04, any other tested hardware configuration hasn’t such issues with software.

The most important questions:

  1. Has MX330 any support for h.264 hardware decoding? its lack of NVIDIA NVENC - NVDEC, isnt it?
  2. Was driver installed without errors? Why GeForce MX330 mention twice?

Neither encoding nor decoding, the MX330 is graphics only.

        Encoder                           : N/A
        Decoder                           : N/A

Yes, works.

Don’t know, you’ll need to ask the Gnome developers why.
