    Hi

    on my dropbox www.dropbox.com logon into it with this credential: user: mrocchini@email.it password: centrale

    forlder: "public" , i have put the file temp.MXF

    I have record it with a sony pdw-f800 camera in SD mode = IMX format [D10]

    Simply I would extract audio so I have one .wav file that contain channel 1 and channel 2 as audio in attachement (16bit 48 Khz].

    In channel 1 is there a microphone, in channel 2 is there the panoramic audio of the camera

    My target is the attached file "temp.mxf" transcoded with avisynth with this script:

    vid= ffvideosource("v:\automazioneclip\input\temp.mxf" )
    aud= ffaudiosource("v:\automazioneclip\input\temp.mxf" )

    left = GetChannel(aud, 1).AmplifydB(6)
    right = GetChannel(aud, 2).AmplifydB(6)


    both=mergechannels(left, right)

    audiodub(vid,both)
    ConvertAudioTo16Bit()
    SoundOut(output = "wav", filename="v:\automazioneclip\output\outputtemp.wav ", type=0, format=1, autoclose=true, showprogress=true, overwritefile="yes")

    Can I use ffmpeg for transcoding audio, without using avisynth?

    Thanks!
