This is my script:

SetMemoryMax(16)
LoadPlugin("v:\automazioneclip\avisynth\plugins\LSMASHSource.dll")

videofile1 = LWLibavVideoSource("C:\Users\Administrator\Desktop\Nuova cartella\C0060.MXF" )
audiofile1 = LWLibavAudioSource("C:\Users\Administrator\Desktop\Nuova cartella\C0060.MXF" )

left1 = GetChannel(audiofile1, 1) 
right1 = GetChannel(audiofile1, 2)
both1=mergechannels(left1, right1) 
audiodub(videofile1,both1)

but I get this error in the audio section:



what could it be?


thanks

The problem is that your source file does not have a single audio track with multiple channels but instead multiple mono tracks. LWLibavAudioSource loads the first (mono) track by default so there is no second channel for GetChannel() to access. You have to make two calls to LWLibavAudioSource() to read two tracks instead of using GetChannel(). Read the README that is included in LWLibavAudioSource() for info on how to select a specific audio track.

Oh my cat: it's so complicated

One thing I should mention: I assume you want to convert 7.1 to stereo audio? You cannot just pick the front left and front right channels (here: tracks). That way you would lose e.g. the center channel where all the talking happens. You need to load all (except LFE?) tracks/channels and make a downmix to stereo from that.
