I've used ffmpeg on an older/slower system like this (500Mhz range), and can tell you that a typical 90 minute movie took well over 2 days to transcode even on an optimized P4. So even accelerated, you'd still be over a day to encode a movie on the N900. It may be quicker if you're not doing video encoding (eg just changing the audio format), but it's pretty intensive even for just that.

you guys serious with this? I have a video converter on pc but using it pushes my core 2 duo from 1 to 5% to 100% usage. What made you think an arm processor with 600mhz could convert a video if a intel dual core processor with 2 2.13ghz and l2 cache is at its limit?

Of course it could. The core2duo is pushed at its limit for speed. Where a video takes 15 mins to be converted with a core2duo, it would take the N900 hours, using 100% CPU usage and making the phone unusable during that time.

So video conversion is possible. Any CPU can handle it. It's just a process. So possible: Yes; Practical: Hardly

If that's the case it really isn't possible for hours of processing to that extent battery drainage(Charger can't supply that much power if processor usage is at 100% even if charger is connected while charging it would still eventually drain out), hardware burn out(Overheating) & software hang up would occur resulting in failure of conversion after. So generally speaking it's 100% impossible.

Oh sorry. I didn't realize you already posted it. I almost never read a whole thread. First posts and last posts usually.
