[linux-dvb] AC3 over DVB

[Hamish Moffatt <hamish@cloud.net.au>]

Hi,

This question is probably off-topic, for which I apologise. However, I
wonder if anyone can help me with getting AC3 sound over DVB-T?
I want to pass it out to S/PDIF, not decode it in software.

It seems that Xine can do AC3 passthrough over S/PDIF, though I never
got any sound out when I tried it. I get stereo sound (PCM) over S/PDIF 
ok. I suspect that its AC3 stuff has been only tested with DVD.

MPlayer can supposedly do it too. I tried it, but it segfaults almost
immediately on the station with AC3 sound. (I just put the AC3 PID in
place of the audio PID in channels.conf.) Once it got as far as the amp
detecting "Dolby Digital 2/0", then crashed, but never again.

It seems like MythTV should also do it, but I've had even less luck with
that, so I thought I'd get Xine or MPlayer working firt.

From my Googling, it seems that AC3 is carried differently on DVB versus
ATSC. I wonder how it is carried on DVD? I wonder if Xine can only do
ATSC (or DVD), and not DVB..
