• Green overlay with multiply blend mode using FFMPEG

  25 mars 2014, par Barto

  I'm currently working on a project which needs video editing.
  Here for I'm using ffmpeg, which is working pretty well, except for 1 filter.
  Every video should get an overlay with the Photoshop multiply blend mode.
  I'm using the ffmpeg blend mode, but unfortunately the video gets a green overlay as you can see in the screenshots.

  Original Image
  

  Edited with ffmpeg

  What I'm trying to achieve
  

  Does this has something to do with the mode I'm working in ?
  Below is my current code
  

  #!/bin/bash
  
  vagrant ssh -c "./ffmpeg \
  
  -i /vagrant/public/uploads/video/bw_RzWecVH02p.avi -i /vagrant/public/img/red_ellipse.png \
  
  -filter_complex "blend=all_mode='multiply'" \
  
  /vagrant/public/uploads/video/overlay_RzWecVH02p.mp4"

  Here is my ffmpeg output
  

  $ overlay_edit.sh

• running multiple FFmpeg instances to encode udp stream gives error

  24 mars 2014, par user2854116

  Please someone help me to fix the problem below

  I am trying to encode multiple udp streams in HLS format. I run one by one instance (process) of encoding on the system. The application is working fine and I was able to encode, receive and play the streams using a player running on a STB (Set Top Box). The encoding was OK till running the 5 th instance. When I started running the 6th encoding instance on the system, the stream output starts freezing in all the 6 encoded outputs.

  I am using a Intel Xeon based Server with 24 cores and 32GB of RAM.

  Here is my ffmpeg build info.
