• Is there any fast methods to download blob video other than ffmpeg ?

  4 juillet 2021, par InVinCiblezz

  I knew we can use

  


  ffmpeg -i 'xxxxx.m3u8' xxx.mp4


  


  to download and format the video.
But it seems pretty slow.
Is there any fast method ?
Thanks a lot !

  


• Trouble downloading a youtube playlist and converting to mp4 with audio/video

  15 mars 2024, par Patrick Coogan

  I am having difficulty with a side project I am working on. The goal of the program is to be able to do a few functions with a youtube video or playlist link.

  


  

  1. download a youtube video and audio and merge them.

  


  2. download a youtube playlist's video and audio and merge them.

  


  3. download a youtube video's audio only.

  


  4. download a youtube playlist's audio only.

  


  


  My main issues arise with the 2. function, downloading a playlist with video and audio and merging them. The program is able to complete function 1 successfully (download a video and audio and merge to one file), and function 3 successfully (download video and output just audio file) Function 4 hasn't been implemented at all yet.

  


  The program is broken into 2 main files : youtube_downloader.py and main.py
The errors I receive from output of running function 2 are listed after the code below

  


  I am hoping for some clarification on what the errors are describing any advice on implementing the second function outlined in comments below.

  


  main.py

• Converting images to youtube supported video using ffmpeg

  15 février 2014, par Kaushik DB

  I'm trying to generate a 1.5hr video for uploading to Youtube using ffmpeg with a 1280x720 screenshot and a audio file.
  I've tried
  but it takes a long time for Youtube to process the video. how can i minimize the processing time.

  ffmpeg -loop 1 -r 2 -i input.png -i audio.ogg -c:v libx264 -preset medium -tune stillimage -crf 18 -c:a copy -shortest -pix_fmt yuv420p output.mkv
