Well basically what i am trying to do is get ruby to read my video files
in so that i can get the dimensions of the video and then place the
dimension sizes in my view. The two formats i need to do this with are
mpeg4 (h.264) and FLV. Is there anyway i can get rails to access the
metadata of these formats and pull the dimensions from the metadata? Any
help would be greatly appreciated.
there is a ruby tool called FLVToole2 from http://www.inlet-media.de/
it parses FLV files and reads/writes metadata.
no idea about mp4, but if you don’t find any lib for that, you can
call ffmpeg from ruby
how do you call ffmpeg from ruby?
I seem to remember answering this very question here on the list, and
searching on ruby-forum.com shows it having been asked three times
someone called Andrew (you or someone else), and answered twice.
for a few answers.
with “system” or just the ffmpeg command inside ``, check out a ruby
tutorial on things like that.
