Anyway, moving on... I believe "ffmpeg -i <filename.ext>" should give you frame count information (along with a bunch of other stuff). It will have to be parsed, of course, but... meh. Also--were you aware that there is an ffmpeg PHP extension? It's even got a nifty instance->frameCount member! :) So, use "ffmpeg" to check on its current frame number, and "ffmpeg -i <filename.ext>" to find out how many there are in total. As Ashley already stated, it won't be completely accurate--but the bar will move a heck of a lot more often/accurately than if you only bump it each time a file is finished transcoding.
