Check audio/stereo function?

[Guest]

Is there a way to check if an avisource has audio and if not - then add a silent audiotrack to it?

c = AVISource(...)
c = c.HasAudio() ? c : AudioDub(c, c.BlankClip())

He he, that's a clever way to do it :) - thanks a lot!

Here's another one for you:

Is it possible to check if a wav is in stereo?

[tried with GetChannel, but it will make an error if there is not 2. channel]

AudioChannels() will tell you.

Nice way to check! HasAudio and HasVideo will be in the next alpha :)

They're not that clever. They're basically the same checks that the internal VideoInfo::HasVideo and VideoInfo::HasAudio methods use.

(And I hope whatever you've added to the alpha version use those methods directly. :) )
