• FFMPEG run time error

  17 mai 2014, par saif

  I added FFMPEG to the references and the build is succeeded but when i run this error is appear

  Could not load file or assembly ’AForge.Video.FFMPEG.dll’ or one of
  its dependencies. The specified module could not be found.

  Looked at the Aforge page
  http://www.aforgenet.com/framework/docs/html/4ee1742c-44d3-b250-d6aa-90cd2d606611.htm and Find this..

  Make sure you have FFmpeg binaries (DLLs) in the output folder of your
  application in order to use this class successfully. FFmpeg binaries
  can be found in Externals folder provided with AForge.NET framework’s
  distribution.

  But I did not understand the meaning of it and how can I do that whether it is the reason of error

• Retranslating video stream using ffmpeg

  6 mai 2014, par zdimon77

  I want to redirect video stream from rtmp to hls format using nginx rtmp-module.

  This my nginx config

      server {
  
      exec_options on;
  
      listen 1936;
  
      chunk_size 4000;
  
  
  
  
  
      application myapp {
  
       live on;
  
       exec /usr/bin/avconv -loglevel verbose -re -i rtmp://localhost:1936/myapp/$name -vcodec libx264 -vprofile baseline -acodec libmp3lame -ar 44100 -ac 1 -f flv rtmp://localhost:1935/hls/$name;
  
  
  
  
  
  }
  
  
  
  
  
  }
  
  
  
  server {
  
  
  
     listen 1935;
  
      chunk_size 4000;
  
  
  
      application hls {
  
          live on;
  
          hls on;
  
          hls_path /tmp/hls;
  
      }
  
  
  
  
  
  
  
  }

  But it doesnt work.
  When I try to publish my stream in console (without exec command in nginx.conf)

  ffmpeg -loglevel debug -re -i rtmp://localhost:1936/myapp/test -vcodec libx264 -vprofile baseline -acodec libmp3lame -ar 44100 -ac 1 -f flv rtmp://localhost:1935/hls/test

  I see this in console

  root@dcv23 :/usr/share/nginx/html# avconv -i rtmp ://localhost:1935/myapp/testname -vcodec copy -an -f flv rtmp ://localhost:1936/hls/testname

  Can someone help me please ?

• Thumbnail is not generated while uploading a video which is downloaded from the same server

  16 avril 2014, par nit3ch

  I am using drupal 7 video module and ffmpeg together to upload video on my site.
  My problem :

  1. Upload a video, everything works fine, thumbnail is generated and video is uploaded successfully
  2. Now download the above uploaded video.
  3. Now Try to upload the same video, on same drupal site.

  Thumbnail is not generating and also I am not able to play the newly uploaded video.
  In all other cases video upload is working fine, I am able to upload same video again and again with no fuss,but when I try to upload the downloaded video , everything goes wrong even if I change the file name after downloading the video and uploading again.

  Please let me know if I am not clear, will try to explain more.
