audio from .mxf file with FFMPEG

[marcorocchini]

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!

ffmpeg -i temp.mxf -map_channel 0.1.0 -map_channel 0.1.1 -af "volume=volume=6dB:precision=fixed" mix6db.wav
