• installing and using ffmpeg-php in my wamp apache

  6 mars 2016, par sonam Sharma

  hey there i am developing a video sharing site and i need to change the video format and get its thumbnail etc i know this can be done by ffmpeg-php library.

  but i have never used any php lib before .
  i have successfully installed ffmpeg to my system (laptop) i can check it by typing library ffmpeg -version to my comand prompt it says something like this

• lavc/hevc : rudimentary support for skip_loop_filter.

  23 juillet 2015, par Nicolas George

  lavc/hevc : rudimentary support for skip_loop_filter.
  + 9% speed on Core i5 on test sample.
  All frames are treated as ref frames, skipping only applies
  
  at level "all". The following mail contains information on
  
  how to improve that :

• Using FFMPEG on AWS lambda

  16 juillet 2015, par Andy Maddio

  I’m trying to use ffmpeg with AWS lambda.
  I followed some guidelines like :

  AWS Lambda making video thumbnails
  or
  https://github.com/binoculars/aws-lambda-ffmpeg

  But still not working on my environment.
  FFMpeg is not found or I can’t run it, and I don’t understand why ...

  I got this kind of error :

   /bin/sh: ffmpeg: command not found

  My folder looks like this :

  -rw-rw-r-- 1 slicer 497 2474        Jul 16 2015     app.js
  
  -rw-rw-r-- 1 slicer 497 31245520    Jul 15 07:08    ffmpeg 
  
  drwxrwxr-x 4 slicer 497 4096        Jul 16 05:22    node_modules 

  In the app.js, I’m calling ffmpeg like this :

  var exec = require('child_process').exec;
  
  var process = exec('ffmpeg -i "http://..." -filter:v "select=not(mod(n\\,25)),setpts=N/((25/1)*TB)" -vsync 0 -s 1600x900 -f image2 "Thumb_%06d.jpg"', {}, function (error, stdout, stderr) {
  
      });

  I tried with

  process.env['PATH'] = process.env['PATH'] + "/" + process.env['LAMBDA_TASK_ROOT']

  Same error and the command "ls -l" is not more available ...
  I tried to change the permissions on the ffmpeg file, with chmod 755 but I don’t have the permission "operation not permitted"

  I upload the zip file with Visual Studio 2013 and AWS Toolkit and I downloaded the FFMpeg file on the johnvansickle website

  What I supposed to do ? What’s wrong with my solution ?

  Thank you,
