How can I tell if a wmv file contains audio? |
|
Is there a way to tell if a wmv file contains an audio track? I have got my fader working, after a number of postings, but if I am playing a wmv file that has no audio, it doesn't make sense to "ramp" the volume up at the start and down at the end, so in this case I would rather leave the volume at the minimum and disable the slider.
