libVLC and AudioBarGraph filter
Posted: 26 Oct 2015 14:22
Hi,
I'm using libVLC in a .NET application (C#) and it works like a charm!
Now I want to use the audiobargraph filter but it doesn't work.
I'm using libVLC this way :
VlcInstance class
VlcMediaPlayer class
VlcMedia class
Application class
The audio meter is present but not showing audio levels:
I've started vlc with the same args and it works flawlessly:
Am I doing something wrong? Is it possible to use audiobargraph in libVLC? If not, anybody got a workaround to integrate audiobargraph in .NET application?
Many thanks,
ampi.
