Hello everyone.  I have some questions regarding FFMPEG.

1) I've read several--all-- the search results that came back for flv2tool/flvtool2 and the results were ambiguous as to whether flv2tool is on the Jimmu server or not.  If so, I was wondering what its path is?

2) I found the path to ffmpeg (/usr/local/bin/ffmpeg) in the forums, but I don't know where this path is relative to root, public_html, or Huh.  I don't see a usr folder via my ftp and I'm not really familiar with the server-side things beyond PHP scripting.

3) I read several people's inquiries about FFMPEG and the tech responses to them which often consisted of statements containing the phrase "CPU intensive" and the possibility of consuming all of one's quota/processor time.  But, these replies were really vague about how many users is "a lot" and similar things that I need to factor in.  What is our quota on CPU time and RAM?  What are the penalties if we overuse?  Do we/when do we get warnings if it seems likely to happen?  Roughly how many video*hours can my users upload and convert before I have to worry that it's too much for our shared server plan?

I've been spread pretty thin for the last week or so.  One of the tasks I've been working on is YouTube's new API so that my users can upload/convert/view videos all on YouTube's processor/bandwidth tab.  However, as is typical with such a public API, they're not going to let you (or the users) not know/forget that they (the API provider) are there.  I don't really want to be affiliated with YouTube for various reasons, nor do I want to have to redirect users to login to YouTube--while logged in to my site already so that they can upload a non-flv file format.  So, when I finally got around to investigating FFMPEG on these forums and found that I could be moved to "a server with FFMPEG installed," I did just that.  I had formed the impression that LunarPages had a few servers with FFMPEG on it and that everything would be fine.  Now, I come to the conclusion that Jimmu is the ONLY server with FFMPEG on it and I'm worried about performance issues--if all of LunarPages' YouTube Clones are on this one server.

This site is the center piece of a nonprofit organization which is in its infancy.  The site was literally only a idea until the founder (& account holder) found me.  All the other dev.s he found were all talk--no action (his words).  Anyway, the point is that there are no members yet, no donations, I won't let him send his grant proposals yet because--everything works on the site, but they can only upload .flvs and I would have to manually create the thumbnails--so dedicated hosting and VPS are definitely not in the budget at this time.  However, we still need to be able to spawn the interest in the site and hopefully generate some donations just-in-time to upgrade the service so that we don't get hit with overrages or warnings.

Thanks a lot--LunarPages really are "out of this world"?!?!?!??? ehehheehee

In most situations, we often recommend that the YouTube clone scripts out there go to VPS or Dedicated hosting due to the server resource issues.  It takes a lot of processing power to turn those video files into flash files.  Now if you could do that off the server - such as with YouTube's API which you mentioned that may be ok.  Would need to be looked at as a case by case situation though.
