how to set the audio channel c#

[tsuncp]

i can play the video
however i cant set the audio channel to 3

always return -1 ..

Code: Select all

[DllImport("libvlc", CallingConvention = CallingConvention.Cdecl, ExactSpelling = true)] [SuppressUnmanagedCodeSecurity] public static extern int libvlc_audio_set_channel(IntPtr libvlc_media_player, int channel);

Found out the reason.

Need to ensure the video is playing , and wait some time , maybe delay 1 second to apply the change
