extract .wav audio from video using libvlcsharp for xamarin forms
Problem to solve
extract .wav audio from video with parameters to set samplerate, bitrate etc.... using libvlcsharp in xamarin forms and save to local disk
Intended users
All Xamarin crossplatform app developers will use this feature.
Proposal
This will be beneficial for xamarin crossplatform app developers as no other crossplatform library exists for xamarin forms for audio extraction.
Documentation
A sample Xamarin cross platform code for android and ios in documentation will be good.

I think that your question belongs to here : https://code.videolan.org/mfkl/libvlcsharp-samples
What you're asking for is not specific to Xamarin.Forms though, it's a basic usage of libvlc with sout
You can find out some info from this code https://github.com/ZeBobo5/Vlc.DotNet/blob/develop/src/Samples/Samples.Core.Recording/Program.cs and adapt to your platform and custom params which you can find here https://wiki.videolan.org/VLC_command-line_help/
Below is my test code, I created a blank xamarin forms project, Added MediaPlayerElement and Button, Added libvlcsharp and libvlcsharp.forms from nuget to my solution for both android and ios. Then i individually added VideoLAN.LibVLC.Android to my Android project and then also added VideoLAN.LibVLC.iOS to iOS project. Added all the fontawesome files, added it to Info.plist to ios project and everything works good. I am able to play video from the location. But somehow i am still unable to extract wav audio file from video with sout option and write to same location.
I tested this on android. I added a file named kuch.mp4 to location "/storage/emulated/0/Download/kuch.mp4" I want to extract wav file to same location "/storage/emulated/0/Download/kuch.wav"
