• i can not upload video in background with delayed_job on heroku ?

  23 novembre 2015, par mokariya

  I used paperclip background process with delay jobs with ffmpeg.

  In paperclip processors folder i have ffmpeg.rb file also.

  my model

  class product < ActiveRecord::Base
  
      has_attached_file :video, :styles => {
  
      :mp4video => { :geometry => "640x480", :format => 'mp4', :convert_options => {:output => {:ar => 44100}} },
  
      :webmvideo =>{ :geometry => "1024x576", :format => 'webm', :convert_options => {:output => {:ar => 44100}} },
  
      :oggvideo => { :geometry => "1024x576", :format => 'ogg', :convert_options => {:output => {:ar => 44100}} },
  
      :thumb => { :geometry => "100x100#", :format => 'jpg', :time => 10 }
  
    },
  
    :storage => :s3,
  
    :s3_credentials => "#{Rails.root}/config/aws.yml",
  
    :processors => [:transcoder]
  
  
  
    process_in_background :video
  
  
  
  end

  Make the intra rd search support 8x4/4x8

  This commit allows the rate-distortion optimization of intra coding
  capable of supporting 8x4 and 4x8 partition settings.

  It enables the entropy coding of intra modes in key frame using a
  unified contextual probability model conditioned on its above/left
  prediction modes.

  Coding performance :
  derf 0.464%

• Is a any way of piping input to deepspeech under Linux ?

  24 octobre 2019, par Unreal Admin

  I am trying to continually stream audio from my IP camera to a server running deepspeech to decode the audio stream to text in realtime using FFMPEG.

  I am using the following command :

  $ffmpeg -i rtsp ://192.168.1.249:8080/h264_pcm.sdp -ar 16000 -ac 1 -acodec pcm_s16le -vn -f wav - |
  deepspeech —model deepspeech-0.5.1-models/output_graph.pbmm —alphabet deepspeech-0.5.1-models/alphabet.txt —lm deepspeech-0.5.1-models/lm.binary —trie deepspeech-0.5.1-models/trie —audio -

  Deepspeech : FileNotFoundError : [Errno 2] No such file or directory : ’-’

  deepspeech doesn’t like the ’—audio -’ specifier.

  Is there any way of achieving the above goal using this approach ? Perhaps deepspeech just isn’t designed to do this ?

  Are there any other suggestions as to how this might be achieved ?

  ffmpeg can be directed to write a .wav file. Deepspeech and transcode this file. But I wish to continually stream and transcode the audio.
