Third revision of my coroutine system (resumable procedures), this time is a static lib written in C++ because the pb version used some deprecated functions that may not work in Macos Silicon. Even is not written in PB i tested on it first and translated the include, it may be useful.
I gave chat ...

I am glad it helped

I think the problem is how PB creates a GDI Plus bitmap from a HBITMAP, because using the api directly works as expected but implies some hacking replacing the pb gdi plus graphics context.

Added the destroy callback on MacOs, when you supply a windowid and a callback in co_create(), the callback will be called when the coroutine has finished, so you can clean up stuff or destroy the coroutine.

Hi,
the fact that reaches the trampoline function is a good sign, i changed some things in macos, can you test it?

I also added some new parameters in co_create, a coroutine cleanup callback in the context of a window application, only for win/linux for now i''ll add it to macos once the basic ...

Fibers are more lightweight and faster when switching, and since only one fiber runs at a time per thread they don't need synchronization like threads. It's task switching vs thread parallel execution.
In one of my projects threads won't work because all the code needed to be executed on the same ...

Download libvlc:

Can you upload a sample of the not working video to somewhere?

Let's say i want to build a crossplatform dll with a function that accepts a string as a parameter.
The dll will be called from another language like C or objective-c for example.
Wich kind of string expects PB on the three paltforms?,
Passing this will work?
LPWSTR windows
const char* linux

Hi, I don't have any uncompressed video to test, it worked with all the avi compressed videos i tried but i noticed that mkv videos don't play, i will look into it later.

I uptated the code with a function to get the supported ranges GetRange(), you can try that before setting the range.

That's an undocumented interface, it will not work.

To set the brightness you need to use DirectShow.
First install the codecs for current video formats:
