### ~~Bug explanation~~ Feature Request Hi and Thanks for your awesome library :) Trying to implement my first WPF project (a media player) based on Material Design but I'm having...

C long / unsigned long should be 4-byte int instead of 8-byte long / ulong?

3

Hi, there is an open issue for FFmpeg.AutoGen bindings [here](https://github.com/Ruslan-B/FFmpeg.AutoGen/issues/217) which I think should be handled from CppSharp. The issue is with C long / unsigned long data types that...

[Question] Targeting .NET 7.0 Directly

ptrdiff_t / size_t data types issue? (and long / ulong)

In my case it looks in vcruntime.h which includes: ```c #ifdef _WIN64 typedef unsigned __int64 size_t; typedef __int64 ptrdiff_t; typedef __int64 intptr_t; #else typedef unsigned int size_t; typedef int ptrdiff_t;...

(SharpGen.Runtime) It seems that when using .NET8 (net8.0-windows framework) it will use by default System.Text.Json v8 which will cause a conflict with the v9? I think a condition to PackageReference...

VideoProcessorStream does not support Past / Future Surfaces

VideoProcessorStream get's a pointer to past / future surfaces (used mainly for deinterlace) but Vortice exposes only a single surface. Is it possible to safely set an array (native pointers)...
