• How To Install FFMPEG on Elastic Beanstalk

  26 mars 2020, 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  This is not a duplicate, I have found one thread, and it is outdated and does not work :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

• RTMP_ReadPacket, failed to read RTMP packet header

  14 juin 2018, par Dilivio Cat

  I am trying to livestream a 24/7 looping stream from my Ubuntu server to youtube.

  I have a gif that is looping and my music gets shuffled from a music list.

  for i in ./*.mp3 ; do echo "file '$i'" ; done | shuf >mp3list.txt ffmpeg -f 
  
  concat -i mp3list.txt -fflags +genpts -ignore_loop 0 -i giffilename.gif -f 
  
  flv rtmp://a.rtmp.youtube.com/live2/(mykeyhere)

  But I am getting this error when I run my script :

  RTMP_ReadPacket, failed to read RTMP packet header : Unknown error
  occutredm/live2/(mykeyhere)

  I did some research, but couldn’t find anything about this specific error. I opened port 1935 and it did not change anything.

  The OS is Ubuntu 16.04 on a VPS.
  Thanks for your help,

  Dilie

• How to cut and concatenate the file so it is not off-beat when the file I got the bpm from is being muxed ?

  27 janvier 2017, par P. Dee

  I am cutting files with ffmpeg based on the bpm I found in a music file. So let’s assume, the file’s bpm = 120. That means, there are 2 bps and 1 beat every 500ms.

  So I cut a video file with multiples of 500ms length, ie 500ms, 1500ms, 3000ms etc. length. But cutting it using

  ffmpeg -ss start -i fileorig.mp4 -t duration part_number.mp4

  and finally creating a mylist.txt with

  file 'part_1.mp4'
  
  file 'part_2.mp4'
  
  ...

  and adding them via

  ffmpeg -f concat -i mylist.txt -c copy output.mp4

  and replacing the audio track with the music file, makes the video be off-beat after some time.

  How to cut and concatenate the file so it is not off-beat when the file I got the bpm from is being muxed ?
