• How to stream (udp) a series of tiff images using ffmpeg

  20 avril 2020, par Michael Carey

  I have written a program that receives images from a camera and then packages the images into a basic tiff format. Then I broadcast the tiff image out on UDP on localhost port 8999.

  



  I then run ffmpeg (on Windows 10) from a command line as follows :

  



  ffmpeg -i udp://127.0.0.1:8999 -preset ultrafast -vcodec libx264 -tune zerolatency -f mpegts udp://127.0.0.1:9000


  



  The idea with the above command is to receive the tiff images from my program, convert them into mpeg, and to then rebroadcast it out on a different port. (once I prove this, I may clip and compress the image as well)

  



  Finally, I open another command window and run ffPlay as follows so that I may see my output :

  



  ffplay udp://127.0.0.1:9000


  



  My output from the ffmpeg command is here :

  



  ffmpeg -i udp://127.0.0.1:8999 -preset ultrafast -vcodec libx264 -tune zerolatency -f mpegts udp://127.0.0.1:9000

• I cant install ffmpeg binary driver on my laravel project

  6 janvier 2020, par oshakab

  I am trying to install ffmpeg binary on my laravel application but I am getting this error. Could not find a matching version of package php-ffmpeg/binary-driver. Check the package spelling, your version constraint and that the package is available in a stability which matches your minimum-stability (dev). I am using laravel 6.4.1

  My composer.json

  {
  
  "require": {
  
      "pawlox/video-thumbnail": "^1.0",
  
      "lakshmaji/thumbnail": "^1.4",
  
      "pion/laravel-chunk-upload": "^1.3",
  
      "pbmedia/laravel-ffmpeg": "^5.0"
  
  },
  
  
  
  "repositories": [{
  
      "type": "vcs",
  
      "url": "https://github.com/PHP-FFMpeg/BinaryDriver.git"
  
  }]
  
  }

  composer require php-ffmpeg/binary-driver=dev-master
  Any Solutions. Thanks
