• ffmpeg live stream to Youtube command line

  30 juin 2020, par brainoverflowse

  Would anyone assist myself with creating the correct ffmpeg command line for an audio and video rtsp camera feed that is 1440 and scale it to 1080 with a max bitrate of 10000 ?

  


• Downloading video & audio segment simultaneously with youtube-dl and ffmpeg

  7 décembre 2020, par Mtaly

  For an online streaming video that I would like to download I have two m3u8 files.

  


  One for the video itself with segment-0.ts to segment-250.ts :

  


  #EXTINF:6.000000,
segment-0.ts
#EXTINF:6.000000,
segment-1.ts
#EXTINF:6.000000,
segment-2.ts
#EXTINF:6.000000,
segment-3.ts
#EXTINF:6.000000,
segment-4.ts


  


  and another m3u8 for the audio segments :

  


  #EXTINF:6.016000,
segment-0.aac
#EXTINF:6.016000,
segment-1.aac
#EXTINF:6.016000,
segment-2.aac
#EXTINF:6.016000,
segment-3.aac
#EXTINF:6.016000,


  


  So, I use youtube-dl and ffmpeg to download the both m3u8 separately then merge them to get the final mp4 (audio+video).

  


  Is there a way to merge the files or use a combined command in the Terminal to automatically download both and merge them ?

  


• 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.
