I have created a system which lets people create a video by uploading images, soundtracks and voiceovers into a form, and with the help of Avisynth, their content is compiled into a video.
I ran into an issue during testing to do with two audio files with non matching channels. i.e. one file was mono, one was stereo.
I am using mixaudio to mix the two tracks together.
I could ConvertToMono on everything, which is a bit of a cop out.
I am aware of MergeChannels and GetChannel, but they both seem to require you to know how many channels a file has before use.
What if you don't know the channels for each soundtrack prior to mixing? Does Avisynth have a way of checking for channels?
