Getting System.AccessViolationException when splitting video into frames

[shubmittal]

I am using ffmpeg to extract frames and iterate over them. The codes iterates correctly over few frames and then then randomly throws error

"System.AccessViolationException: 'Attempted to read or write protected memory. This is often an indication that other memory is corrupt.' Any suggestions on how to resolve it? System details and screenshot below:

Me too have the exact same problem. After some frames it can randomly throw this error. I use the latest (yesterday) code from GitHub and the Zeranoe shared builds, 64-bit Windows. My program is in .NET Core 3.1. I am converting mpeg1 files to images.

Thank you for the answer I got by mail. I don't understand why I can see it here. But in any event I removed the "!" in front of requireDsiposing (above) and now I don't get any sudden accessvioloations, it works. Thanks!!!
