7 is good for testing at least. My receiver loads the Dolby Digital Decoder on Sunday when I watched 7HD's loops. Most of the time though, Dolby Pro Logic II is used on all AC3 APIDs on every channel. Not sure if this's a bug in Myth or the stations just broadcast them in 2 channels (although there's a Dolby Digital watermark that says surround sound).Just so you have another point of reference...
I get stuttering on the HDTV video too. I haven't had any success with AC3 yet, but I haven't tried very hard. So my testing is based on Seven HD, which has the MPEG stream too. And yes, it is a lower bitrate than Nine or Ten, but they crap out on me at the moment because of the AC3.
No ideas on this yet. :( I previously tot my CPU wasn't fast enough (2.6 o/c'd to 2.8) ..It seems to stutter (~50% of the time) if I *change* to an HD channel. If I start on the HD channel, it works fine. If I record HD and start watching the recording straight away, it works fine too.
I thought about pausing the stream for a short while to see if the stutter would go away, but that doesn't work. So what is it about a channel change?
Yes you should (havn't tested it on Mark's patch though). It's a bit crude, on my system, add the line "DEFINES += CONFIG_AC3" in both config.h (you can do that automatically by running "configure --enable_a52" I think) and in settings.pro. Do a distclean and recompile myth.I'm having a look at Mark Anderson's patch now to see what makes it tick. Should I be able to get this working with software AC3 decoding?
There's also this option "--enable_a52bin" you can play about with (but this doesn't work last time I was on Mandrake 10.1 CE)..
Also in Mythtv settings->general (or something), make sure "AC3 Passthru" is off.
Regards.
