• ffmpeg: not found when running ffmpeg via php xampp (mac)

  28 August 2021, by Alex Styl

  I am trying to execute ffmpeg from php. I have installed ffmpeg locally on my mac via homebrew and I am able to run the commands I need via terminal.

  


  When I try to execute the following code:

  


  &lt;?php&#xA;    echo "Starting ffmpeg";&#xA;    $output = shell_exec("ffmpeg -i test.mp3 -codec:a libmp3lame -b:a 128k out.mp3 2>&amp;1");&#xA;    echo "<pre>$output</pre>";&#xA;?>&#xA;

  


  I am receiving the following on my browser:

  


  


  Starting ffmpeg

  


  sh: 1: ffmpeg: not found

  


  


  I am assuming that I somehow need to install ffmpeg to my xampp server but it is not obvious how to do that. After searching online I can find linux and Windows tutorials but I couldn't figure out something out by looking at them.

  


  What I tried doing was to download the ffmpeg static build form https://ffmpeg.org/download.html#build-mac and placed it in the htdocs holder, and then tried to execute ffmpeg as if it was an executable (after changing chmod), but that gave me

  


  


  sh: 1: ./ffmpeg: Exec format error

  


  


  How would one go and install and then run ffmpeg on their xampp server?

  


• Can I use HTTP/2.0 for downloading HLS streams using FFmpeg?

  8 June 2024, by SpongeBed

  I am trying to download an HLS stream using FFmpeg. However, FFmpeg defaults to HTTP/1.1 for downloading content, and the video source's firewall blocks HTTP/1.1 connections. Consequently, FFmpeg cannot download the video.

  


  I used the same headers as my browser to access the content and replicated the request using Insomnia. And again, my request was blocked when using HTTP/1.1.

  


  I've searched everywhere but haven't found any information on how to change the HTTP version FFmpeg uses for requests.

  


  Is there a way to configure FFmpeg to use HTTP/2.0 instead of HTTP/1.1?

  


• Merging audio and video files both in mp4 format in python [duplicate]

  24 January 2021, by Anuj Dhillon

  This is my first question here.

  


  I am trying to write a script in python to download videos from reddit. In reddit both videos and audios are downloaded separately in mp4 format. I've managed to download both the audio and video files.

  


  Now I want to merge these files together. I know it can be done in python with ffmpeg but I have no idea how it works when the audio is in mp4 format. Any help would be appreciated.
