• ffmpeg - How to determine if -movflags faststart is enabled ? PHP

  3 juin 2015, par IIIOXIII

  While I am able to encode an mp4 file which I can play on my local windows machine, I am having trouble encoding files to mp4 which are readable when streaming by safari, etc.

  After a bit of reading, I believe my issue is that I must move the metadata from the end of the file to the beginning in order for the converted mp4 files to be streamable.

  To that end, I am trying to find out if the build of ffmpeg that I am currently using is able to use the -movflags faststart option through php - as my current outputted mp4 files are not working when streamed online.

  This is the way I am now echoing the -help, -formats, -codecs, but I am not seeing anything about -movflags faststart in any of the lists :

  exec($ffmpegPath." -help", $codecArr);
  
  for($ii=0;$iibr>';
  
  }

  Is there a similar method of determining if -movflags fastart is available to my ffmpeg build ? Any other way ? Should it be listed with any of the previously suggested commands ? -help/-formats ?

  Can someone that knows it is enabled in their version of ffmpeg check to see if it is listed under -help or -formats, etc.?

  TIA.

• Rails : Encoder error when converting video using FFMPEG on Heroku

  2 janvier 2013, par andmcgregor

  I'm trying to upload a video and convert the file to mp4 and reduce the file size using the paperclip-ffmpeg and paperclip gems. Everything works fine running a local server and I'm only getting this problem on heroku. I have ffmpeg installed in vendor/ffmpeg/ (I followed these steps : https://gist.github.com/3963576). Here is the code I've got and the error I'm getting :

  models/video.rb :

  class Video < ActiveRecord::Base
  
    attr_accessible :content, :user_id, :video
  
    has_attached_file :video , :styles => { 
  
      :medium => { :geometry => "500x500", :format => 'mp4',
  
          :convert_options => { :output => { :vcodec => 'libx264',
  
          :b => '1000k', :bt => '200k',
  
          :acodec => 'libfaac', :ab => '56k', :ac => 2 } } }
  
    }, :processors => [:ffmpeg]
  
  
  
    belongs_to :user
  
  end

  when I run heroku logs :
