• How To Install FFMPEG on Elastic Beanstalk

  13 avril 2017, par Nick Lynch

  This is not a duplicate, I have found one thread, and it is outdated and does not work :
  Install ffmpeg on elastic beanstalk using ebextensions config.

  I have been trying to install this for some time, nothing seems to work.
  Please share the config.yml that will make this work.

  I am using 64bit Amazon Linux 2016.03 v2.1.6 running PHP 7.0 on Elastic Beanstalk

• ffmpeg is preferring to encode in VP9 but I'm trying to encode in VP8

  1er septembre 2016, par user1689634

  I’m trying to encode webm video files specifically in VP8, but ffmpeg is forcing VP9. I’m using -c:v libvpx, which to my knowledge is supposed to be VP8, but when it encodes I see it’s encoding in VP9 instead :

  ffmpeg -framerate 7 -loop 1 -i "C:\converted\cover.jpg" -c:v libvpx
  
  -i "C:\converted\Image.wav" -b:v 50k -c:a libvorbis -b:a 96k
  
  -vf scale=-1:300 -shortest -metadata title="%artist% - %album%" 
  
  -metadata author="%artist%" -threads 8 -y "C:\converted\%artist% - %album%.webm"

  The build I have does have --enable-libvpx and --enable-libvpx-vp9 flags. It is also the latest default static build, I made no changes, just extracted it : ffmpeg-20160828-a37e6dd-win32-static.zip

  I was using an outdated build for a long time and updated today. I can’t find any documentation online to help me with this problem.

• Ffmpeg not able to access file on aws labmda

  1er septembre 2016, par Surendra Agarwal

  I am using ffmpeg to create video thumbnails on AWS Lambda. I downloaded the file in /tmp directory but ffmpeg is not able to access it and giving error

  [Error : meta data contains no duration, aborting screenshot creation]

  when I am checking the media info using ffmpeg then it is giving the output

  { ffmpegversion: 0, title: '', artist: '', album: '', track: '', date: '', durationraw: '', durationsec: 0, synched: false, major_brand: undefined, video: { container: '', bitrate: 0, codec: '', resolution: { w: 0, h: 0 }, resolutionSquare: { w: 0, h: NaN }, rotate: 0, fps: 0, stream: 0, aspect: 0, pixel: 0 }, audio: { codec: '', bitrate: 0, sample_rate: 0, stream: 0 } }

  I used fs module to check file existance on that location and it is giving the output
