Im using a customs processor to run ffmpeg on a video to create a
thumbnail.
So far so good. Except when I do:
cmd = "-i #{@file.path} -f flv -s 320x240 ~/Downloads/foobar/q.flv"
success = Paperclip.run(''ffmpeg'', cmd)
Console is reporting:
ffmpeg ''-i /var/folders/uL/uL0bYOOZEZaJH5E+BmDJVE+++TI/-Tmp-/stream,
16824,1.mpeg -f flv -s 320x240 ~/Downloads/foobar/q.flv'' 2>/dev/null
I believe the problem is because Paperclip inserts single quotes when
executing ffmpeg.
It works if I manually type in console (ie. without single quotes):
ffmpeg -i /var/folders/uL/uL0bYOOZEZaJH5E+BmDJVE+++TI/-Tmp-/stream,
16824,1.mpeg -f flv -s 320x240 ~/Downloads/foobar/q.flv
How can this be fixed?

Check that your Rails app knows the real path to ffmpeg. In at least one of my apps, I have needed to provide a root-relative path to ffmpeg in order to have any conversion work.

I do that because i convert the video from whatever format to flv along with the thumbnail and that takes time , if i do that in the main thread it will cause my app to freeze for each conversion, that is why i moved to a worker process. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

radhames, that sounds good. would appreciate that.
One other way, I''ve gotten it to work is in my model:
before_save :process_thumbnail
private
def process_thumbnail
system("ffmpeg -i #{self.media.to_file.path} -f flv -s 320x240 ~/
Downloads/foobar/q.flv")
end
But I dont know if this is a clean way of doing it. Is it? Will I have
problems with the app hanging as you mentioned?

Radhames, what do you think? I am guessing the article at http://www.google.com/url?sa=D&q=http://thewebfellas.com/blog/2009/2/22/video-thumbnails-with-ffmpeg-and-paperclip&usg=AFQjCNHbJbsr5cjILbhrgpvOot5qJhUPsw assumes that the uploader would be the admin, so there is no need for startling or a workling? But if the app allows users to upload, then a startling/workling approach is needed since ffmpeg takes a while to process uploaded files?

Hi Radhames, ok, then I will definitely need to use a workling and a startling for this. Since my users are the ones uploading. By the way, in Heroku hosting (http://heroku.com/pricing), a workling would be a worker right? So whenever I implement a workling in my app, it would trigger the workling in Heroku? Am I understanding this right? Let me know when you get your example up.

I guess what I am asking is. If my app allows users to upload content, which uses ffmpeg, and takes a while decode audio/video, will this trigger the workers at heroku automatically? Therefore, I don''t need to use a workling/startling? Or do I still need to implement a startling/workling for this to prevent the app from ''hanging''?

Ok I''ve gotten it to work. For everyone that is interested or devs who
stumble across:
Model class:
has_attached_file :media,
:styles => { :small => ''94x58#'',
:medium => ''188x116#'',
:large => ''376x232#'' },
:url => ''/assets/artists/:artist_id/
videos/:id/:style.:extension'',
:path => '':rails_root/public/assets/
artists/:artist_id/videos/:id/:style.:extension'',
:processors => [:video_thumbnail]
------------------
/lib/paperclip_processors/video_thumbnail.rb:
module Paperclip
class VideoThumbnail < Processor
attr_accessor :geometry, :whiny
def initialize(file, options = {}, attachment = nil)
super
@file = file
unless options[:geometry].nil? || (@geometry
Geometry.parse(options[:geometry])).nil?
@geometry.width = (@geometry.width / 2.0).floor * 2.0
@geometry.height = (@geometry.height / 2.0).floor * 2.0
@geometry.modifier = ''''
end
@whiny = options[:whiny].nil? ? true : options[:whiny]
@basename = File.basename(file.path, File.extname(file.path))
end
def make
dst = Tempfile.new([ @basename, ''jpg''
].compact.join("."))
dst.binmode
cmd = "ffmpeg -itsoffset -4 -i #{@file.path} -y -vcodec mjpeg -
vframes 1 -an -f rawvideo -s #{geometry.to_s}
#{File.expand_path(dst.path)}"
begin
success = Paperclip.run(cmd)
rescue PaperclipCommandLineError
raise PaperclipError, "There was an error processing the
thumbnail for #{@basename}" if whiny
end
dst
end
end
end
------------------
/config/initializers/paperclip.rb
Paperclip.interpolates :artist_id do |attachment, style|
attachment.instance.artist.id
end
# Ensures that files have the proper extensions. i.e. thumbnails with
jpgs
Paperclip.interpolates :extension do |attachment, style_name|
case attachment.instance.class.to_s
when "Video"
if style_name.to_s == ''original''
''flv''
else
''jpg''
end
when "Audio"
if style_name.to_s == ''original''
''mp3''
end
else
File.extname(attachment.original_filename).gsub(/^\.+/, "")
end
end
# Path to ffmpeg
Paperclip.options[:command_path] = "/opt/local/bin"

Hope this helps somebody

No worries. Hope you get better soon :-) Redhames, you seem pretty experienced with Paperclip.
