yes, extracting from ac3 to multi-channel wav is not available as
default, but can be enabled by applying the patch below.
running ffmpeg like this
% ffmpeg -ac 6 -ar 48000 -i foo.ac3 foo.wav

It seems feasible:
We start with:
static int AC3_encode_init(AVCodecContext *avctx)
And the struct AVCodecContext contain the number of channels:
typedef struct AVCodecContext {
int bit_rate;
int bit_rate_tolerance; /* amount of +- bits (>0)*/
int flags;
int sub_id;/* s

I have only ever tested it in mono. Not sure 5.1 works. My original
interests were real-time AC3 encoding. However, it looks like even a
1.4G
Ok,
I get the code through the CVS, I'll take a look by myself.
Thanks a lot. :-)

Hi,
Thanks, it seems you're right:
AC3 encoder
- Generates Fully compliant AC3 bitstreams.
- Mono and stereo modes supported.
- Handles low bitrates modes.
- Use only integer computations (suitable for low end processors).
But, does it support more than mono and stereo (I mean,

Hi,
Is there some softwares to encode AC-3 (aka Dolby Digital)?
And if not, is there some attempt to do it ?
It seems that there is some patent on it, but there is still
some documentations freely accessible about it (not very detailled).
For example, on http://www.dolby.com/:
