• How install ffmpeg on wamp server (windows 7 - x64)

  15 avril 2015, par MoonLight

  Please take a look at all these depricated links :
  http://stackoverflow.com/search?q=Install+ffmpeg+in+windows

  i installed wamp server on my windows 7 (x64) machine and want to install ffmpeg on it.

  here is my wamp server version :
  wampserver2.5-Apache-2.4.9-Mysql-5.6.17-php5.5.12-64b

  

  here is the official web site of ffmpeg :
  http://ffmpeg-php.sourceforge.net/

  i am really confused where can i download ffmpeg extension for php5.5.12 and how install it ?
  in their official web site there is only one link for download :
  http://sourceforge.net/projects/ffmpeg-php/

  and those downloaded files need perl to run and there is no dll files inside them.
  would be really appreciate to help me step by step to install ffmpeg in my wamp server.

  Quelques syntaxes sont incomprises par le compilateur spip (2 ou 3)

  Exemples :

  #SETtel,(#TEL
  #SETweb,(#WEB
  #SETmel,[(#WEB|non) (#EMAIL]
  Le message d’erreur est : "Argument manquant dans la balise SET".

  Ici, il semble que c’est ok selon les types de balises utilisées en argument :
  - 2 balises avec des arguments, c’est bon.
  - 2 balises sans arguments, c’est bon.
  - une balise avec et une balise sans, c’est pas bon.

• Can ffmpeg transcode an audio track and add it as a second audio track at the same time, or if not, how to do it as separate commands ?

  31 mai 2020, par wb6vpm

  A bit of history. I am using Plex as my media server, but for reasons unknown, it has issues transcoding the DTS-HD MA 7.1 audio to EAC3 stereo and keeps buffering (the server has plenty of horsepower on all fronts, CPU/RAM/drive space & speed, gigabit networks connections for all devices. The playback device (TCL Roku TV, with a 3rd party soundbar connected via HDMI ARC) doesn't support the built-in 7.1 audio, so I get silence if I play it back directly by putting the file on a USB stick.

  



  Also, I am by no means a ffmpeg guru, I figured out what I do know by Google University and asking questions, so please be kind and forgive me if I ask follow-up questions that may seem n00b-ish, and please provide example commands (preferably in the context of my command below so that I can have a known point of reference to start with).

  



  I have a movie with 4K (HEVC Main 10 HDR) video and DTS-HD MA 7.1 audio that I am looking to leave the video and audio untouched, but to add a 2nd audio track in either EAC3 or if necessary, just AC3 in stereo

  



  So what I am looking for is as follows :

  



  video.mkv

  



  

  • Existing->4k video file (no change)

  


  • Existing->7.1 audio (no change)

  


  • Convert and add->stereo audio as a 2nd audio track to the output.mkv file

  


  



  Below is the command I've historically used with ffmpeg to convert and replace the audio file with the stereo audio, but since I'd prefer to leave the 7.1 audio in place, this doesn't work :
ffmpeg -i "D:\video.mkv" -c:v copy -c:a aac -b:a 128k "D:\output.mkv"

  



  And if this cannot be done as a single command, please also let me know what steps I do need to take to be able to do it.

  



  Thanks in advace,
Mike
