• How to overlay swf files on a video

  17 décembre 2015, par Harsha Vardhan

  Hi recently I started working with ffmpeg, there I overlay-ed images as well as gif files on videos. Where coming to swf files ffmpeg is unable to recognize that format.

  I tried below command for overlaying :

  ffmpeg -i vid.mp4 -i swf.swf -filter_co
  
  mplex overlay=x=100:y=100:shortest=1  -q 15 -vcodec libx264 out.mp4

  Any one please suggest me, how to resolve this issue or even getting frames from swf format files by using ffmpeg or any other similar tools.

• How to install libx265 for ffmpeg on Mac OSX

  20 mars 2016, par Spencer

  I have tried multiple guides here (search for "Building libx265") and here with no success. Both times I made sure I uninstalled ffmpeg first, went through the guides, then ran

  brew install ffmpeg --with-fdk-aac --with-freetype --with-libass --with-libvpx --enable-libx265

  No matter what when I go to run a command like

  ffmpeg -i source.mkv -c:v libx265 test1.mkv

  I get the error :

  Unknown encoder 'libx265'

  Has anyone had success building libx265 for use with ffmpeg on OSX and can you please share how you did it ?

  P.S. I am running OSX 10.11.3
