Cannot Open SVO2 with Zed Studio + Zed Diagnosis Crash

Software
1

Hi,

I encountered two issues related to SVO2 recording and diagnostics.

1. Large SVO2 files cannot be opened in ZED Studio

I recorded SVO2 files using both:

  • the C# API

  • ZED Studio

Recording finishes normally, but when the SVO2 file becomes large, ZED Studio fails to open it:

  • the viewer stays black for a while

  • then it shows “cannot open”

From my tests:

  • H265 Lossless recordings always fail to open

  • H265 sometimes works, but larger files (around >4GB) often fail as well

2. ZED Diagnostics crashes during camera check

To solve the first problem, I want to run the zed diagnosis. But when I run ZED Diagnostics with the camera connected, it crashes during the camera check step (around 10%).

Because of this, I could only export diagnostics without the camera connected, so the attached report mainly contains system information.

I will attach:

  • the ZED Studio error screenshot

  • the ZED Diagnostics report

Questions

  • Any suggestions on how to troubleshoot the SVO2 playback issue in ZED Studio and ZED Diagnostic crash issue?

  • Would it help if I upload some SVO2 file that cannot be opened?

Thanks!

Hi,

I got exactly the same problem with three different computers. I use a ZED M.
In addition, I can’t record SVO files with ZED Explorer (I did it in the past with old SDK versions).
In copy, my file from ZED Diagnostic.

Hi @FelicienT and @waystogetthere

What version of the ZED SDK are you using?
