• How to use Python to capture thumbnails from online videos without downloading the entire video ? [closed]

  28 septembre 2023, par gaowanliang

  When watching online videos, the web player can always drag the progress bar without having to download the entire video. This is thanks to the Range in the header, which can specify the range for playback. But I can’t find a way to use Python or ffmpeg to capture a part of the video content from a network video.

  


  The program does not need to be very accurate in how long it takes to capture a screenshot, but it does not need to download the entire video completely.

  


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

  28 août 2021, par 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 juin 2024, par 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 ?
