Progressive download/"fast start"

[ChetWesley]

Is there a way to do progressive download or fast start as it is referred to by apple, via ffmpegx? Specifically, I am looking to do .mp4 videos or .mov with progressive download.

I don't find much info about it in the archive, but maybe I am missing something.

Thanks

Or use mp4box with the hint command,
mp4box -hint yourfile.mp4

I have seen some mp4box binaries for mac os x, like http://www.tkn.tu-berlin.de/research/evalvid/EvalVid/mp4box-mac.tar.bz2 or google for it.

Thanks for the tip. I don't quite understand how the application is used, but I can probably figure it out with some tinkering. I am a command line noob.

I just found some mention online of qt-faststart which is supposedly a tool that comes with ffmpegx, but I can not find any simple instructions on how it is used or where I locate the tool to use it.

mp4box -hint yourfile.mp4

works, i do it a slightly different way. make a file called fix.sh file which contains:

#!/bin/bash

for i in $*
do
  ~/Desktop/MP4Box -add ${i}#video final_movie.mp4 || continue
  ~/Desktop/MP4Box -add ${i}#audio final_movie.mp4 || continue
  mv final_movie.mp4 ${i}
  mv ${i} fixed/
done

place mp4box on your desktop, or wherever, just make sure the path is correct in fix.sh
i keep fix.sh in a directory called "fix" which contains a subdirectory called "fixed"

in terminal:

cd /Users/yourname/Movies/fix
./fix.sh *.mp4
