Using pipes for he-aac

[Guilllo]

Hi all !

I've got a 6 channels ac3 file I want to convert in He-AAC 5.1

But i can't decode ac3 file to wav cause it needs to much free space on my disk. I'd like to encode the output without it being writed to the disk. The problem is that I use wine and He-AAC encoder command line from nero for windows.

Any idea ?

Thanks

Use Avisynth method with BeHappy or Bepipe.

Use Avisynth method with BeHappy or Bepipe.

wine==linux
i'm not shure AviSynth or BeHappy will work on it
maybe better way will be to use ffmpeg as ac3 to wav decoder and redirect it to neroAac via pipe

Try this :

$ mkfifo audiodump.wav
$ wine ./neroAacEnc.exe -ignorelength -q 0.3 -if audiodump.wav -of output.mp4 & mplayer input.ac3 -af channels=6:6:0:0:1:1:2:4:3:5:4:2:5:3 -ao pcm:waveheader:file=audiodump.wav -channels 6
