ZED_Depth_Viewer crashing on SVO playback when ZED_Explorer works as expected with same SVO file

Hardware ZED2

Hello,

I am running the ZED_Explorer on a recorded SVO files. It works as expected on my Ubuntu 22.04 laptop with ZED SDK 4.0.7 and CUDA 12.1.105.

However, when I try to run the ZED_Depth_Viewer and playback the same SVO file, it crashes the application. Below is the error:

$> ZED_Depth_Viewer
in bool ImageHandler::initialize(sl::Mat&) : Err [999]: unknown error.

Any ideas what might be casing this? Please see attached Zed_Diagnostic_results.json file.

I reviewed a few threads with the ZED_Depth_Viewer crashing but they were different stack traces than I am experiencing.

Thanks!

So after reading the related threads again, I was able to follow the steps here to resolve this issue on one of the computers:

https://support.stereolabs.com/hc/en-us/articles/8422008229143.

On the other computer running 22.04 this did not work, rather, after using the command

$ sudo prime-select query
nvidia

and seeing the correct output, I cannot see the correct output from

$ glxinfo | grep OpenGL
X Error of failed request:  BadValue (integer parameter out of range for operation)
  Major opcode of failed request:  152 (GLX)
  Minor opcode of failed request:  24 (X_GLXCreateNewContext)
  Value in failed request:  0x0
  Serial number of failed request:  66
  Current serial number in output stream:  67

and when running the ZED tools, I see

$ ZED_Explorer 
 ** [SVO] Hardware compression (NVENC) available **

I updated the above post because this solution only worked on one of my two platforms.
