• Embed a Youtube with a MP4 File as poster

  29 août 2021, par adampl

  I want to embed a youtube video with a 10 second silent looping MP4 file as the poster.

  


  Currently, I am using the Wordpress video shortcode with my MP4 as the poster source, it works on some browsers but not all. Can anyone help ? I would prefer to find a pure HTML solution separate to the wordpress shortcode as I will need to get this to work on other CMSs.

  


  [video src="https://www.youtube.com/watch?v=[videoID]" poster=<video autoplay="autoplay" loop="loop" muted="muted" playsinline="playsinline">&#xA;  <source src="/wp-content-directory/intro.mp4" type="video/mp4">&#xA;</source></video>]&#xA;

  


  What i have found is to get a looping MP4 work on all browsers, I have to use this tag with the autoplay loop muted and playsinline

  


  <video autoplay="autoplay" loop="loop" muted="muted" playsinline="playsinline">&#xA;<source src="/directory/intro.mp4" type="video/mp4">&#xA;</source></video>&#xA;

  


• Batch script to convert, youtube-dl webm file to mp3 with ffmpeg

  1er avril 2024, par SneakyShrike

  I'm using youtube-dl to extract the best possible audio quality from youtube videos. However the best quality audio usually turns out to be the webm format, which isn't useful. I would like to write a batch script that converts the webm file to an mp3 with ffmpeg. I've already tried using this guide on reddit to do it, but it doesn't seem to work. It appears to create an empty mp3 file that displays an error when i try to play it and the meta data is also completly blank.

  



  Here is the batch script :

  



  for %%a in ("Downloaded\*.*") do %CD%\ffmpeg\bin\ffmpeg.exe -i "%%a" -vn -ar 44100 -ac 2 -ab 192k -f mp3 "Converted\%%~na.mp3" pause


  



  I'll also give an explanation of how the whole thing should work.

  



  The idea is, is that you use youtube-dl to extract the best possible audio, then put that file into the Downloaded folder (see pic below) and then you run the mp3 script (which uses commands from ffmpeg) to convert the webm file in the Downloaded folder to a mp3 file, and place it in the Converted folder. The mp3 script is the code above. But it doesn't seem to work properly.

  



  I'm not very familiar with batch scripting, nor with ffmpeg so any help would be appreicated.

  



  Here is the picture to complement the explanation part.

  



  

  


• Is it possible to seek through streamed youtube audio with discord.py (play from a given timestamp in the video) ?

  13 juin 2020, par apc518

  Unfortunately passing in a URL with a &t= tag does not cause discord.py's VoiceClient to start playing at that timestamp. I'm using youtube_dl.

  



  Is is possible to seek through audio within discord.py in order to start streaming a YouTube video from somewhere besides the start ?

  



  I know some professional bots like Groovy have seek commands for streamed YouTube videos, so the Discord API itself is capable of this.

  



  The code I'm using is from here.
