I am running a OSX, don't know tons about video conversions. But I have like 200 videos that are all in mp4 format and won't play in Firefox. I need to convert them to ogg to use the html5 video tag.
These files live in a folder structure that makes it hard to do files one at a time. I would like the bash command or Ruby command to go through all child folders and find all .mp4's and convert them.
I found one reference of how to do this with Google: http://athmasagar.wordpress.com/2011/05/12/a-bash-script-to-convert-mp4-files-to-oggogv/
#!/bin/bash
for f in $(ls *mp4 | sed ‘s/\(.*\)\..*/\1/’)
do
ffmpeg -i $f.mp4 -acodec vorbis -vcodec libtheora $f.ogg
done
But have no idea how to convert this from linux to osx.
