[DOC] Provide Screen Recorder Example

Hello, I've been trying to figure out astiav for a while now, I was wondering if it's possible to provide a example to capture the screen using github.com/kbinani/screenshot from a image.RGBA to a file (io.Writer).

It would be very helpful :)

Edit: Mostly the important part being how to properly convert a *image.RGBA / *image.RGB to a *astiav.Frame

There's actually already an example for frame data manipulation (maybe its name is misleading). Check out the use of FrameData.FromImage() here to see how to use it.

Does that answer your question?

should we try adding printf statements to cli ffmpeg to log what values they're passing to these functions to better understand it?

this line seems to parse the filter graph options.

[asticode]

Sure, sounds like a good idea. Could you also confirm the filtering example works in your Windows env? 🤔

[CypherpunkSamurai]

Ok looks like filter doesn't work on windows at all.

Now that you're saying it, it actually rings a bell since I had to disable filters' unit tests for windows github action since it was crashing with no error message whatsoever 😭 I really want to fix that, if possible 🤔

If you're up to it, could you try running go test in go-astiav after having deleted the comments at the top of filter_graph_test.go and let me know if you get any valuable information that would indicate where the problem is coming from? If not, no bother, I'm sorry for mentioning the filters even though it didn't work on Windows 😱

Sure Can. Been Completing my project, I'll check it next. I'll try checking if i replicate the bug in c, then try port the working code to go.
