Crash Trace - VLC or Nvidia Issue?

[aitte]

I'm trying to solve [url=https://trac.videolan.org/vlc/ticket/20483]this bug[/url] (so I'm on Windows 64-bit, with a GTX 1060, etc.)

I finally got the debug version of VLC built and ran it with gdb attached. I'm seeing this stack trace (I've included the gdb logs as well):

Code: Select all

I recently updated the Nvidia drivers from versions that were about a year old to the newest, and got the same crash. I know you're going to claim it's an Nvidia driver problem, but how do we know it's not a bad call to the api? I.e., bad memory address, or passing buffers or objects that have been corrupted by something in vlc?

I don't see any code from VLC in the stack. How is the code above getting called by VLC? Does the nvidia driver run some sort of a queue thread where you can submit rendering requests and they're run in the background?

I'm having zero other problems with 3D games and other video players. The only crash is from VLC.
