• FFMPEG : Stream a file with original playing rate

  21 novembre 2012, par sajad

  I want to stream a file to the network using ffmpeg in it's original frame rate ; so I can play the generated UDP stream using some receiver client such as VLC. I used this command :

  ffmpeg -i "myfile.mpg" -sameq -re -f mpegts "udp ://127.0.0.1:2000"

  By using this command the ffmpeg starts streaming the file in a very high rate ; such that streaming of a file that has about 30 minutes length, is finished after just about 40 secs. I want to see the file in original rate. Also I want to have control on rate of video to play it faster or slower. Is there any options to do this ? thank you.

• Playing videos using HTML5 Tag

  20 novembre 2012, par Haja Mohaideen

  I am creating a website where videos need to be streamed. The content creator uploads .mov file to the server. Upon uploading, I convert to the following formats using FFMPEG, .mp4, .webm, and .ogg.

  I am now trying to allow the video to be viewed from multiple browsers and handheld devices. The code is as follow :

  <code class="echappe-js">&lt;script&gt; <br />
  
  var video = document.getElementById(&amp;#39;video&amp;#39;);<br />
  
  video.addEventListener(&amp;#39;click&amp;#39;,function(){<br />
  
   video.play();<br />
  
   },false);<br />
  
  &lt;/script&gt;
  &lt;script type=&quot;text/javascript&quot; src=&quot;http://stackoverflow.com/feeds/tag/jwplayer.js&quot;&gt;&lt;/script&gt;
  
  &lt;script type=&quot;text/javascript&quot;&gt;<br />
  
    jwplayer(&quot;video&quot;).setup({<br />
  
      modes: [<br />
  
         { type: &amp;#39;html5&amp;#39; },<br />
  
         { type: &amp;#39;flash&amp;#39;, src: &amp;#39;player.swf&amp;#39; }<br />
  
      ]<br />
  
    });<br />
  
  &lt;/script&gt;
  

  The video works on all browsers. But, it is refusing to play on Android. When I click the play button, it shows as loading only.

  I am testing on 4.0.3.

  FFMPEG conversion codes :

  webm

  exec("ffmpeg -y -i file.mov -acodec libvorbis -ac 2 -ab 96k -ar 44100 -b 345k -s 640x360 output.webm", $command_output, $result);

  ogg

  exec("ffmpeg -y -i file.mov -acodec libvorbis -ac 2 -ab 96k -ar 44100 -b 345k -s 640x360 output.ogv", $command_output, $result);

  flv

  exec("ffmpeg -y -i file.mov -ar 44100 -ab 96 -f flv output.flv", $command_output, $result);

  For MP4 :

      sudo ffmpeg -i file.mov -s 320x240 -c:v libx264 -pix_fmt yuv420p -profile:v baseline -preset slow -acodec aac -strict experimental -ac 2 -r 15 -ab 44100 -aspect 16:9 output.mp4

• How to configure ffmpeg on ubuntu to convert *.3gp to pcm *.wav ? [migrated]

  31 juillet 2012, par Monica Sol

  I'm using linux Ubuntu ver 10.04.
  I need to convert file *.3gp to PCM *.wav. I'm using for that ffmpeg program.

  When it's installed from repository by using aptitude install ffmpeg it's installing some basic version of it and I cannot convert what I need.

  I've read some stuff on the Internet and I've made what there was written.
  I've installed the latest yasm ver.1.1.0 and the newest x264 - 0.125.2208. After that I got ffmpeg using git from http://ffmpeg.org/download.html (git clone git ://source.ffmpeg.org/ffmpeg.git ffmpeg).

  I`ve tried to configure ffmpeg by myself using :

  ./configure --enable-gpl --enable-version3 --enable-postproc 
  
  --enable-nonfree --enable-swscale --enable-pthreads --enable-libmp3lame 
  
  --enable-libx264 --enable-libopencore-amrnb --enable-libopencore-amrwb

  than : time make && make install.

  Till this time everything was ok. After conversion (ffmpeg -i audiotest.3gp -f s16le -ar 8000 -acodec pcm_s16le audio.wav) I wanted to check information about this PCM *.wav file (ffmpeg -i audio.wav) and I`ve got this error :

  ~# ffmpeg -i audio.wav
