[Mplayer-dev-eng] MPlayer on IRIX ... (fwd)

With which libmpeg2-version ? :-) (It has changed quite a bit in the last
time)

Yepp, I nearly thought so ...

I am not good at those byte order problems, could you maybe give some
examples (maybe from the code) of which pitfalls I should avoid ? 
Is it mainly about taking care of the right order when reading from byte
streams ?

Exactly .... pfff ...

Yepp, that's good - and a friend of mine here, Patric, has made code to
take better advantage of the MIPS-architecture - using double instead of
int ! ;) ;)

Hmmm, I need both the code from mpg123 and mp3lib ? 
Ah, mpg123 is using mp3lib, right ?

Yes, definitely, I wouldn't have hassled with anything else in the moment
(although I already have an SDL up and running on this machine, but I
won't trust it yet)

You mean: Stay on this list ? :-)

Ah, it feels much safer now that I know what to do - and it is good to
know that there are no other opensource-projects for MPEG2-playback on
IRIX - gives the whole thing a bit of a pioneer-feeling ;) 

Servus,
  Gernot

BTW: If you ever feel that these questions get too much for you (I have
nearly 6 hours/day available for this project during the next time),
please tell me so, and I will shut up for a while ;)
