hi,
i am using the directshow in C# to built a karaoke system,but i am facing a
problem with the audio play in the video file (DAT format), some of the video
file , i can control the music and vocal play by using the BALANCE in the
directshow. but some of the video file will only play the music and without
the vocal .
i have no idea why this happen , it that because of different of mpeg format
? how can i know what mpeg format are using (all the video file format i'm
using is in DAT extension).
or i should use others methods(?) to control the audio play in the video
file .
