This is more or less my default for pushing videos over flash player
using progressive download (not streaming):

a. ffmpeg -i some.file -pix_fmt yuv420p -vcodec libx264 -preset medium
-tune film -crf 21 -threads 0 out.mp4
(This is video only, for audio i use afconvert when on mac or neroaac
when on linux or windows)
b. audio extraction, replaygain, encoding to AAC
c. muxing video and audio
d. qt-faststart or mp4box (to move the atom, or was it electron? not sure)

p.s. afaik "cheap" php streaming is still possible by using flv
container (with h.264+AAC inside)
