  • Convert video with paperclip and ffmpeg in Ruby on Rails

    16 juin 2014, par Atu

    I want to convert my uploaded video with ffmpeg, but I had few error. I use paperclip and ffmpeg but nothing happen. The structure of my application is one post has_many videos.

    this my video model :

    belongs_to :event
    
validates_attachment_presence :source
    
has_attached_file :source
    

    
after_create :convert_in_flv, :set_new_filename
    

    
def convert_in_flv
    
  flv = File.join(File.dirname(source.path), "#{id}.flv")
    
  system("ffmpeg -i #{source.path} -ar 22050 -ab 32 -s 480x360 -vcodec flv -r 25 -qscale 8 -f flv -y #{flv}")
    
end
    

    
def set_new_filename
    
  update_attribute(:source_file_name, "#{id}.flv")
    
end

    and this my video controller

    def create
    
  @event = Event.find(params[:event_id])
    
  @video = @event.videos.create(params[:video])
    
  redirect_to event_path(@event)
    
end 
    

    
def destroy
    
  @event = Event.find(params[:event_id])
    
  @video = @event.videos.find(params[:id])
    
  @video.destroy
    
  redirect_to event_path(@event)
    
end

    The video is successful upload but not converted. You had any solution ?

  • iOS convert video with FFMPEG programitically(no use ffmpeg command)

    22 novembre 2012, par user1239775

    I am going to convert video captured from camera to mpeg format using FFMPEG for reducing the size of video file.
    I converted the video to mpeg with 'CODEC_ID_MPEG1VIDEO. But the audio was not played.
    I didn't find the reason.
    My video format is h264 & aac.

    Please help me.
    Thanks in advance.

  • EC2 for video-encoding

    24 septembre 2012, par TK Kocheran

    I have a potential job which will require me to do some video encoding with FFMPEG and x264. I'll have a series of files which I'll need to encode once, then I'll be able to bring down the instances. Since I'm not really sure of the resource utilization of x264 and FFMPEG, what kind of instances should I get ? I'm thinking either a

    High-CPU Extra Large Instance

    7 GB of memory
    20 EC2 Compute Units (8 virtual cores with 2.5 EC2 Compute Units each)
    1690 GB of instance storage
    64-bit platform
    I/O Performance : High
    API name : c1.xlarge

    or, alternatively a

    Cluster GPU Quadruple Extra Large Instance

    22 GB of memory
    33.5 EC2 Compute Units (2 x Intel Xeon X5570, quad-core “Nehalem” architecture)
    2 x NVIDIA Tesla “Fermi” M2050 GPUs
    1690 GB of instance storage
    64-bit platform
    I/O Performance : Very High (10 Gigabit Ethernet)
    API name : cg1.4xlarge

    What should I use ? Does x264/FFMPEG perform better with faster/more CPUs or does it really pound the GPU more ? In any case, it seems that the Cluster GPU seems to be the higher performance instance. What should I prefer ?
