[mythtvnz] Multithreaded H.264 playback

[Aaron Whitehouse]

Hello all,

My 2002 MythTV PC has finally given up the ghost and I am replacing it
with a new AMD 780G setup. We are limited to analogue (one software bttv
card and a hardware Hauppauge PVR 150) as we don't have the correct
aerial or DVB cards.  One day soon, I would like to move to DVB-T HD.
I'm a long time member of this list and know about VDPAU etc.

I am currently trying to decide on the CPU and am choosing between a
cheap Sempron LE-1200 and a cheap dual core Atlon X2 5000+ (or similar).
 What I was hoping someone could tell me is: what speed dual core I
would need to decode Full HD H.264 in software once the ffmpeg-mt
patches trickle down into the binaries?  Obviously, in an ideal world,
AMD would release open specs of the UVD2 chips, or at least include
support in the Catalyst drivers.

If I would need some ridiculously expensive chip, then I may as well buy
a cheap Sempron and replace it in the future (when prices come down) if
I ever need to decode HD in software. If I could decode HD on an X2
5000+, then I would likely buy one of those and take advantage of better
multitasking etc. in the interim.

Thanks for your help,

Aaron
