Not using AVI audio

[Cyberia]

If I want to load an AVI using AVISource, and the AVI has audio, but I would rather use a WAVSource, can I?

What if I wanted to keep the AVI audio AND add a WAVSource?

How would I script these?

[KpeX]

AVISource(string filename [,...], bool "audio", string "pixel_type")

That's from the AviSynth documentation. So if you wanted to load an AVI without sound, something like

Audiodub(Avisource("myfile.avi",audio="false"),Wavsource("myfile.wav"))

should do the trick. As far as your second question, do you mean two audio tracks? I don't know of any way of scripting that with avisynth.

[Cyberia]

Wow I missed both of those. Thanks.

But can AudioDub accept multiple audio streams? Doesn't look like it.

WRT multiple tracks, the only way to "mux" it with Avisynth would be to use additional channels (e.g. 3-4).

Could you post more specific what you want to do?

Ok, let me be perfectly clear. I don't have an immediate need for this. I'm not exactly sure if there is any advantage in doing this, but it seems like a neat idea to try. I was just playing around with AviSynth and wondered if I could do something like this:

video=avisource("myavi.avi, false)
audio1=wavsource("mywav1.wav")
audio2=wavsource("mywav2.wav")
audiodub(video, audio1, audio2)


or even more exotically:

video=avisource("myavi.avi)
audio1=wavsource("mywav1.wav")
audio2=wavsource("mywav2.wav")
audiodub(video, audio1, audio2) <--potentially 3 audio tracks.


this version has the correct syntax, but would it work?

video=avisource("myavi.avi)
audio1=wavsource("mywav1.wav")
audiodub(video, audio1) <--potentially 2 audio tracks.

not clear.

Do you want 2 audio tracks playing at the same time, or do you want selectable tracks?

[Cyberia]

either.

is either possible?

[Richard Berg]

Using Avisynth alone, only the former is possible, and only then if you have a player that can decode 4-channel (or 6-channel, etc.) PCM audio. You'll have to use MergeChannels (http://www.avisynth.org/index.php?page=MergeChannels).
