Video Processing Library in dotnet core

[Junaid-Amjad]

I know it is not a right question in this forum but it would be helpful if i get to know about video processing library used/worked in Avalonia or dotnet core? It is just a general question.

ffmpeg should work fairly well. Consider using https://github.com/Ruslan-B/FFmpeg.AutoGen for interop.

Okay, i think i didn't elaborate my video processing. I want to display the Live Stream in wpf application and later save the stream in video(where ffmpeg will be useful). In wpf it can be achieved using mediaelement but it is not exist in the Avalonia-WPF. Is there any alternative library which can be used in Avalonia

You can use ffmpeg and output the stream into WritableBitmap or draw via ICustomDrawingOperation for better performance.

performance is the first pirority. Is there any link where i get to know about ICustomDrawingOperation.

Note that Render(IDrawingContextImpl context) usually happens on the render thread (but sometimes can happen on the UI one), so you need to provide thread-safety locks yourself.

Not tried it, but there's now Avalonia suuport in LibVLCSharp I think: https://code.videolan.org/videolan/LibVLCSharp/-/issues/7

It is a good control but it don't support frame event.
