please, ac3 to aac & aac5.1 to spdif?

28th July 2005, 16:24

I read all the faq on doom and other forums but I still have no succesful results under Linux.

Hrere what I do:

AC3 5.1 to AAC 5.1
I do:

Rip the AC3
mplayer video.vob -dumpaudio -dumpfile audio.ac3

Covert the AC3 to 6 channel PCM
a52dec audio.ac3 -o wavdolby > audio6.wav

Covert PCM to AAC 5.1
faac -q 100 -I 5,6 -P -R 48000 -C 6 -X audio6.wav -o audio.aac

Play the aac
faad audio.aac -w | mplayer -

---> I got on SPDIF a stereo AAC that play 2 times faster?!
instead of AAC 5.1 to the normal speed <----

How do I solve this dilemma?

why mplayer doesn't read the aac directly? faad support is enabled

Code:

$ mplayer audio.aac -ao faad
MPlayer 1.0pre7-3.4.3-20050110 (C) 2000-2005 MPlayer Team

Any advice is welcome!
