Running qtfaststart in a folder containing multiple .mp4's

Question

I have a library of videos, all of which need to be adjusted for web-streaming by putting the moov atom ahead of the rest of the video with qtfaststart. This allows playback to begin before the client has completely downloaded the video.

How can I do this? Should I run a .sh script directed to that folder to run qtfaststart? If so, how would such a script look like?

Answer 1

All you have to do is:

for f in *.mp4; do qtfaststart "$f"; done

This works because qtfaststart will overwrite the input file automatically.

If you want this done recursively, you could use find:

find . -type f -name '*.mp4' -exec qtfaststart {} \;

Or with shell globs (e.g. in Bash 4):

shopt -s globstar
for f in **/*.mp4; do qtfaststart "$f"; done
