• creating mp4 url from m3u8 url from ffmpeg

  17 mai 2016, par user3440716

  I have a m3u8 url :

  http://esioslive6-i.akamaihd.net/hls/live/202874/AL_P_ESP1_INTER_ENG/playlist_1000.m3u8

  and i am trying to convert this link to mp4 in url form.

  what i am trying :

  ffmpeg -i  http://esioslive6-i.akamaihd.net/hls/live/202874/AL_P_ESP1_INTER_ENG/playlist_1000.m3u8 -c copy -bsf:a aac_adtstoasc http://esioslive6-i.akamaihd.net/hls/live/202874/AL_P_ESP1_INTER_ENG/output.mp4

  is it possible ?

  code which i am trying :

  <?php
  
  $i = "ffmpeg -i  http://esioslive6-i.akamaihd.net/hls/live/202874/AL_P_ESP1_INTER_ENG/playlist_1000.m3u8 -c copy -bsf:a aac_adtstoasc http://esioslive6-i.akamaihd.net/hls/live/202874/AL_P_ESP1_INTER_ENG/output.mp4";
  
  
  
  ?>
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  <video controls="controls" tabindex="0" autoplay="autoplay" loop="loop">
  
  <source src="&lt;?php">></source></video>

  I am new and I also saw this post FFMPEG mp4 from http live streaming m3u8 file ? but i dont understand why something is not happening.

• poster adjustment after getting it from video

  30 juin 2016, par Jass

  I am capturing poster from this video https://www.youtube.com/watch?v=wg-kEWsL6Xc using following code. Video can be any, I am just giving example.

  shell_exec('ffmpeg -y  -itsoffset -4  -i "'.base_path().'/assets/videos/'.$file_name.'.mp4" -vcodec mjpeg -vframes 1 -an -f rawvideo -filter:v scale=1170:ih*1170/iw "'.base_path().'/assets/videos/thumbnail/'.$file_name.'.jpg"')

  Width = 1170px,

  Height= 300px (as it is background image so it does not matter)

  But I am facing adjustment problem. Following are my current views

  First : Head is cutting, here I am using css property background : url(’completepath’) center no-repeat ;
  

  Second : Showing black portion on top of head. This is the original image that I am getting from ffmpeg code.

  

  My Question : But I need image like in you tube, you can notice that in all videos we can see top portion of humans without being cutting even black portion is well adjusted.

  Currently I am downloading and testing with youtube videos but in actual job seekers will make their own videos using android/iphone or any camera and will upload on our site.

  so how i can overcome this issue means show image with proper human face and body ?

  thanks in advance.

• dashjs can't find initialization segment on manifest.mpd

  30 avril 2016, par Abelardo Mendoza

  I am following this tutorial to stream a WebM. I have no issues running the ffmpeg commands to generate the videos/audio/manifest files but when I try to run it locally, there’s no video or audio at all and dashjs floods the console with :

  Searching for initialization.    
  
  Start searching for initialization.     
  
  Perform init search: http://localhost:8080/video_1280x720_500k.webm    
  
  Perform SIDX load: http://localhost:8080/video_640x360_750k.webm     
  
  Perform SIDX load: http://localhost:8080/video_1280x720_500k.webm 

  Writing that to console until I stop the server. I have tried using other mpd files such as this, which is used on the dashjs quickstart and it plays the video without any problems.

  I used this guide to install the latest version of ffmpeg on Ubuntu 14.04 LTS :

  When running on ffmpeg :

  ffmpeg \
  
   -f webm_dash_manifest -i video_160x90_250k.webm \
  
   -f webm_dash_manifest -i video_320x180_500k.webm \
  
   -f webm_dash_manifest -i video_640x360_750k.webm \
  
   -f webm_dash_manifest -i video_640x360_1000k.webm \
  
   -f webm_dash_manifest -i video_1280x720_500k.webm \
  
   -f webm_dash_manifest -i audio_128k.webm \
  
   -c copy -map 0 -map 1 -map 2 -map 3 -map 4 -map 5 \
  
   -f webm_dash_manifest \
  
   -adaptation_sets "id=0,streams=0,1,2,3,4 id=1,streams=5" \
  
   manifest.mpd

  It generates the following manifest.mpd :

  The index.html has a few changes because dash.js changed the way the player gets initialized.

      
  
          
  
          
  
          <code class="echappe-js">&lt;script src=&quot;http://cdn.dashjs.org/latest/dash.all.debug.js&quot;&gt;&lt;/script&gt;
  
              
          
  

  And here is Chromium’s log file. I’m converting this webm from this site.

  If I missed out any other relevant information or if anyone can guide me into the right direction, please let me know.

  Edit :

  Like Will Law mentioned, using the Shaka Player worked without any issues with my current manifest. Hope this helps anyone else.
