In video controller, create action. I am using FFMPEG to generate a
thumbnail of videos that are uploaded.
The tempfile is created as such:
def create
......
dst = Tempfile.new(basename)
dst.binmode
system("ffmpeg -itsoffset -4 -i #{file.path} -y -vcodec mjpeg -
vframes 1 -an -f rawvideo #{File.expand_path(dst.path)}.png")
....
end
As you can see from above, ffmpeg outputs a file to the var dst which
is an instance of Tempfile. In console, when I do:
ls /var/folders/uL/uL0bYOOZEZaJH5E+BmDJVE+++TI/-Tmp-/

I see a bunch of files in the directory. It seems that rails did not
automatically delete these temp files. Should I manually delete these
files?
I am worried that, if my temp dir fills up with temp files, it'll
eventually take up most of the server space...
Your thoughts on this matter?
