[FFmpeg-user] slow starting...

[Bouke]

Guys,
First of all, i'll have to admit i'm pretty new on this...
I've build a very basic version of FFmpeg on OSX, and send it to someone 
else (of course on the other side of the world, so i can't toy with his 
machine),
together with a front end app. (that fires shell commands)
On my site all works swell. However, with the other guy FFmpeg seems to 
start slow (see the output below, and this is a 'not so bad'  example, there 
are cases where FFmpeg is stuck on 0 FPS for a very long time).
I'm using a custom start time, and a duration for the encode
First thing that is funny, if FFmpeg is stuck on the beginning, it sez a 
start time of 100000000000 or so. What's up with that? Cannot be right...
What could be wrong? I've only send him the (about 5 MB) application. Is he 
missing something that was build on my machine elsewhere?
(I cannot believe that, if i boot from a fresh install drive it works here 
also)
Another question, i've build on a quad core machine, but the other party has 
an 8 core. Now from my understanding Threads can be as high as twice your 
cores.
On my machine that's the case, i can go up to 8. So i would expect that on 
an 8 core machine Threads can be set to 16, but no go...
Does it matter on what machine the build is done?

Thanks for any insight,

Bouke
