• How to integrate a video editor into a web application [on hold]

  20 juin 2016, par Nick Lynch

  I am looking to figure out how to integrate a video editor into an application i’m building, using php (laravel 5).

  I am experienced in php development, and how to play and other front-side aspects of video, but I cannot find much on how to actually edit video on the server side. I have found FFMPEG or Kaltura may be the way to go, but i have found very little about those or if they are the right tools.

  Please let me know the best way to actually implement a video editor into my app

  Thank you !!!

• How to make Nginx HLS application pull RTMP on request

  31 août 2020, par aroquev00

  This is my situation : I want to use Nginx to serve streams over HTTP using HLS. The thing is, I want the HLS streams to be generated/started when I get a request for them.

  


  I can successfully achieve this behavior with RTMP, as I have the following config file

  


  application myApp {
  live on;    
  exec_pull myScript.sh $app $name;
  exec_kill_signal term;
}


  


  In my myScript.sh file I have something like this :

  


  ffmpeg -i sourceLink.m3u8 -codec copy -bsf:a aac_adtstoasc -f flv rtmp://localhost/$APP/$NAME;


  


  So that when I request rtmp://myAddress/myApp/someLink it works perfectly.

  


  However, I want to stream HLS instead of RTMP. I have seen other solutions that do this by having an application that starts the RTMP module and pushes it to the HLS application. However, what I want is that when I recieve a request for an HLS stream THEN the RTMP is started (which starts the FFmpeg), and as soon as the requests for the stream are over the RTMP stops receiving requests and thus stops the FFmpeg.

  


  Here is my config file with what I have tried so far :

  


  application myHLSApp {
  live on;
  pull rtmp://localhost:1935/myApp/someLink name=test static;
  # Turn on HLS
  hls on;
  hls_path /mnt/hls/;
  hls_fragment 3;
  hls_playlist_length 60;
  # disable consuming the stream from nginx as rtmp
  deny play all;
}


  


  My main objective is to start the FFmpeg in myScript.sh ONLY when it is needed to then stream that incoming file as HLS from my machine. Any ideas ?

  


  Thanks a lot for the help !

  


• Application slower on jar than eclipse building with ant

  28 novembre 2019, par Caio Farias

  Hello guys, i’m facing a silly problem.

  I’m using the javacv library to capture streaming videos. On the eclipse i run my application and the delay time it is only the response of rtsp. But when i generate a jar file(using ant, a build.xml) and run on terminal (sudo java -jar app.jar) takes a 4 min to start grabbing frames.

  I run the flag verbose on java(java -verbose - jar) and the delay time its because his loading the libs ffmpegs(so files).

  Anyone had any idea how to improve and minimize the time ?
