• How to stop and pause a video using ffmpeg

  1er juin 2017, par Amartya2562

  I am trying to make a video player using scilab gui. I am using scilab gui in the front end and ffmpeg in the back end. I am able to start the video but I cannot stop or pause it. Any idea regarding how to stop and pause the video will be appreciated thoroughly ?

• Mapping Video streaming URL with SPRING MVC

  31 mai 2017, par Valeriane

  I’m developping a site for video streamings.

  My application server works with spring MVC (front is managed by angular).

  I have another server, that provides stream flux (uses ffmpeg).

  Today I have direct URL to my video server, something like that :
  http://myvideos_server.com/videos/video.m3u8

  this URL is detectable client side....

  Is it any technic do not provide my videos streaming URL directly ? Is it possible mapping videos stream URLs with Spring MVC ?
