• Download encrypted TS files from video stream

  8 janvier 2021, par albertma789

  Following this post, I usually download transport stream (.ts) files by using the browser's developer console to find the URLs of the .ts files and then I use wget to download them. After that I use the ffmpeg -f concat method to combine them into an mp4 file.

  



  Recently I come across a site that streams videos and I used the same method to download all the .ts files. The site is here. After I downloaded all the individual .ts files, I use ffmprobe to check the file format but realized the .ts files cannot be understood by ffmpeg/ffmprobe. While the site uses http (not https) I thought the streams are not encrypted so I tried to open the .ts file in an hex editor but I don't know what format it is (but they don't look like zip/gz). My question is : are the transport steams encrypted ? If yes, is there a way to decrypt them ? If not ? Can anyone point me to the right direction such that I can make ffmpeg understand them ?

  



  An example transport stream (first & second) are here and here but the link might expire in a bit. In that case you will need to open the site in developer console to find the updated link to the .ts files.

  



  The site uses JW Player 8.0.0

  


• file input from http (url) in melt plugin

  26 décembre 2017, par Anuj TBE

  I’m using MELT plugin for generating crossfade animation using series of images.

  I found the corssfade animation script from here.

  and the script is

  melt -verbose \
  
  -profile atsc_720p_25 \
  
  001.png out=50 \
  
  002.png out=75 -mix 25 -mixer luma \
  
  003.png out=75 -mix 25 -mixer luma \
  
  004.png out=75 -mix 25 -mixer luma \
  
  005.png out=75 -mix 25 -mixer luma \
  
  -consumer avformat:output.mp4 vcodec=libx264 an=1

  But instead of providing file from local path, I want to use http url like

  melt -verbose \
  
  -profile atsc_720p_25 \
  
  http://example.com/image1.jpg out=50 \
  
  http://example.com/image2.jpg out=75 -mix 25 -mixer luma \
  
  http://example.com/image3.jpg out=75 -mix 25 -mixer luma \
  
  http://example.com/image4.jpg out=75 -mix 25 -mixer luma \
  
  http://example.com/image5.jpg out=75 -mix 25 -mixer luma \
  
  -consumer avformat:output.mp4 vcodec=libx264 an=1

  But it gives

  No LADSPA plugins were found!
  
  
  
  Check your LADSPA_PATH environment variable.

  and full output is

  No LADSPA plugins were found!
  
  
  
  Check your LADSPA_PATH environment variable.

  21 janvier 2018, par tommyvisagroup

  I use nginx for windows to create htl and rtmp server to run in windows 10
  I download nginx from this link http://nginx-win.ecsds.eu/download/

  Here is my configuration file content

       }
  
    }
  
  }

  I had crreated html/hls folder
  but when I try to run nginx.exe nothing happens, no nginx.exe in task process

  nginx.exe can run when I remove this part of config file

  hls on;
  
  hls_path "/html/hls";
  
  hls_fragment 3;
  
  hls_playlist_length 60;

  please help me to fix it, many thanks :D
