• Issue with video.js playing AES encrypted video

  2 septembre 2021, par r3dge

  I'm trying to use video.js to play an encrypted HLS video. The AES 128 encryption has been done using this method : FFmpeg video encryption

  


  Here is the html code :

  


  &#xA;    &#xA;    <source src="http://192.168.56.1/enc/prog_index.m3u8" type="application/x-mpegURL">&#xA;</source>

  
 
 
 


  Video.js is loaded using CDN :

  


  <code class="echappe-js">&lt;script src=&quot;https://unpkg.com/video.js/dist/video.js&quot;&gt;&lt;/script&gt;&#xA;&#xA;&#xA;&lt;script src=&quot;https://unpkg.com/@videojs/http-streaming/dist/videojs-http-streaming.js&quot;&gt;&lt;/script&gt;&#xA;

  


  The player is loading and appears in the browser but the video can not be played.

  


  I get two warnings in the console :

  


  video.js:159 VIDEOJS : WARN : A plugin named "reloadSourceOnError" already exists. You may want to avoid re-registering plugins !

  


  VIDEOJS : WARN : Problem encountered with playlist 0-http://192.168.56.1/enc/prog_index.m3u8. Trying again since it is the only playlist.

  


  Server side i'm using Apache with Symphony 5. The server return a HTTP 200 status for the first ts file of the video. When i press the play button of the player seems to retry downloading. It get a 200 each time but the video is not played.

  


  Update : i tried to play the same video without encryption and it works. The problem seems to be due to the encryption itself.

  


  Thanks in advance for any help on that issue.

  


• ffmpeg video concate not working when one video is generated from a single image

  16 décembre 2017, par Sid

  what I am doing is generating a video of 5 secs from a single image using FFmpeg.

  for that I’m using the following command :

  -loop 1 -i image.jpg -c:v libx264 -t 5 -pix_fmt yuv420p -crf 25 -s 1280x720 Out.mp4.

  Now I want to concatenate this video with another one.

  I am able to do this for other videos with the following command

  -y -i input1.mp4 -i input2.mp4 -strict experimental -filter_complex [0:v]scale=1280x720,setsar=1:1[v0][1:v]scale=1280x720,setsar=1:1[v1] ;[v0][0:a][v1][1:a]
  concat=n=2:v=1:a=1 -ab 48000 -ac 2 -ar 22050 -s 1280x720 -r 30 vcodec
  mpeg4 -b 2097k output.mp4

  But when I join the video generated from the image, the videos do not join as the second input does not have an audio because it is generated from the image.So is there any way to join these two videos using -filter_complex in FFmpeg ?

• Create animation video or applying different different effect on video from set of images

  8 janvier 2016, par Mehul Dudhat

  I tried with ffmpeg but it’s not showing any effect with created video. I tried below command with FFMPEG lib.

  ffmpeg -f image2 -r 1/5 -i /&lt;<dir path="path">>/img/img%d.jpg -vcodec libx264 /&lt;<dir path="path">>/output_video.mp4
  
  </dir></dir>

  The image generated video : https://flic.kr/p/CWtxhi

  Is there any other library available to add effect or animation on video during the creation from set of images ?

  I would like to give this type of animation or effect https://animoto.com/play/rXBG1fIq9FWN00O7R7wKyQ
