• Downloading a Few Seconds of Audio from a Youtube Video with ffmpeg and youtube-dl Results in [youtube] : No such file or directory error

  20 décembre 2018, par DrJessop

  Below is the program that I wrote :

  ffmpeg -ss 60 -t 10 -i $(youtube-dl -f 140 https://www.youtube.com/watch?v=kDCk3hLIVXo) output.mp3

  This is supposed to get 10 seconds of audio starting at the one minute mark of the video and write it to output.mp3. If I run the youtube-dl command separately, and then the ffmpeg command with the entire video audio as input, it works. But, I do not want to download the entire video as well as create a new file with only a few seconds of audio.

  In its current state, I am getting [youtube] : No such file or directory errors. Does anyone know how I can fix this and keep it in one line ?

• How can I allow my users to combine audio and video tracks for downloading a youtube video ? [closed]

  1er décembre 2023, par Faizan Ahanger

  I have a website which, along a bunch a text, has a embedded youtube videos to play. I want to allow my users to also a be able to download those videos. There are too many videos there to store on my own server and I know that there are already website like y2mate.com and savefrom.net which do this.

  


  I used yt-dlp and using the --print-json parameter I can get the urls for downloading the files but the audio and video tracks are not combined for higher videos. Using ffmpeg seems to be the obvious solution but I don't understand where the videos should be combined. Should I download both needed tracks on my server and combine them before serving it to users ? This seems very inefficient as it take a lot of bandwidth for handling all download requests. There is also this library ffmpeg.wasm which according to them is "a pure WebAssembly / JavaScript port of FFmpeg enabling video & audio record, convert and stream right inside browsers !"

  


  This should work but it will require the users to download a 30MB webapp before they can download any video. This is also not very efficient, especially if they are downloading a video which is only a few MBs in size.

  


  Are these the only two options that I have or is there a better way to do this ?

  


• facing problem in downloading the audio data of a trimmed youtube video using youtube-dl and ffmpeg libraries

  15 mai 2022, par rkc

  I'm trying to download the audio content of a trimmed YouTube video using youtube-dl (v2021.12.17) and FFmpeg (v4.2.2) libraries in python, on Windows 10 PC. I am able to download the audio data when the command is executed on the Pycharm terminal, but not able to download the same content when using os.system() command.

  


  For example, I'm able to download the data when I execute

  


  "ffmpeg -ss 30 -t 10 -i $(youtube-dl -f best -g https://www.youtube.com/watch?v=3NGZcpAZcl0) -- output1.wav"


  


  command on the Pycharm terminal.

  


  But, i'm getting an error, when I try to execute the same in the Editor window as shown below,

  


  os.system('ffmpeg -ss 30 -t 10 -i $(youtube-dl -f best -g https://www.youtube.com/watch?v=3NGZcpAZcl0) -- output1.wav')

error: $(youtube-dl: No such file or directory


  


  I also tried enclosing the $() link in quotes and then executed it. But, after doing this, I am getting a different error as shown below

  


  os.system('ffmpeg -ss 30 -t 10 -i "$(youtube-dl -f best -g https://www.youtube.com/watch?v=3NGZcpAZcl0)" -- output1.wav')

error: $(youtube-dl -f best -g https://www.youtube.com/watch?v=3NGZcpAZcl0): Invalid argument


  


  So, can any of you help me in resolving this error ?
