• Installing full multimedia stack on server (ffmpeg,mp4box,sox,mplayer)

  29 avril 2015, par hdezela

  I’ve had a trusty text file with all(?) the steps I need to set up a full multimedia stack on a RHEL compatible server (CentOS, AWS Linux, etc.) for a few years now. However, sometimes some things are missing and I need to revise it. I know it is not complete so I’m asking for suggestions/modifications in order to get a good - and public - list of how to install all this stuff easily.

  Ideally, I want to be able to run through the file and end up with a system that’ll take any media file and be able to convert/encode/decode/whatever with it.

  This is what I have :

  yum install mesa-libGL-devel mesa-libGLU-devel libXi-devel libXmu-devel freeglut-devel freeglut ncurses-devel
  
  cd /usr/local/src
  
  mkdir /usr/local/src/tmp

• H.264 adds broken still frames to the end

  14 mai 2015, par Panupat

  I’ve been using ffmpeg to encode raw AVI into H.264 MP4 for about 2 years without problem. However, in my recent project we’re using 60 fps for the first time and face some weird results.

  Here’s an example file. It has 82 frames. FFMPEG would produce the correct result from frame 1 to 82. Here’s a capture at frame 82.

  http://imgur.com/VCIcoVH

  Then, we get this still frame added to the end, from frame 83 to 157.

  

  Am I doing something wrong in my command ? I tried with almost no options.

  ffmpeg -y -i "C:\tmp\uncompressed.avi" -r 60 -vcodec libx264 "C:\tmp\compressed.mp4"

  Tried a couple different options, the problem still occurs.

  ffmpeg -y -i "C:\tmp\uncompressed.avi" -r 60 -vcodec libx264 -keyint_min 12 -vb 4000k -vprofile high -pix_fmt yuv420p -f mp4 "C:\tmp\compressed.mp4"

  Tried with FFmpeg Win64 Static and Shared build by Kyle Schwarz.

  Appreciate any help, thank you !
