[vlc-devel] how to change stereo to mono

[Sukrit Sangwan]

I am new to vlc. I read the code of karaoke filter. It was written set
output to mono.
I have set the output format to mono. Please check if its correct or not.


diff --git a/modules/audio_filter/karaoke.c b/modules/audio_filter/karaoke.c

     }

     (void) filter;
     return block;
 }
