• youtube-dl python script postprocessing error : FFMPEG codecs aren't being recognized

  23 septembre 2016, par stackPusher

  My python script is trying to download youtube videos with youtube-dl.py. Works fine unless postprocessing is required. The code :

  import youtube_dl
  
  
  
  options = {
  
      'format':'bestaudio/best',
  
      'extractaudio':True,
  
      'audioformat':'mp3',
  
      'outtmpl':'%(id)s',     #name the file the ID of the video
  
      'noplaylist':True,
  
      'nocheckcertificate':True,
  
      'postprocessors': [{
  
          'key': 'FFmpegExtractAudio',
  
          'preferredcodec': 'mp3',
  
          'preferredquality': '192',
  
      }]
  
  }
  
  
  
  with youtube_dl.YoutubeDL(options) as ydl:
  
      ydl.download(['http://www.youtube.com/watch?v=BaW_jenozKc'])

  Below is the output I receive :

  I get a similar error if I try setting ’preferredcodec’ to ’opus’ or ’best’.
  I’m not sure if this is relevant, but I can run the command line counterpart fine :

  youtube-dl -o 'test2.%(ext)s' --extract-audio --audio-format mp3 --no-check-certificate https://www.youtube.com/watch?v=BaW_jenozKc

  I’ve gotten a few clues from the internet and other questions and from what i understand this is most likely an issue with my ffmpeg, which isn’t a python module right ? Here is my ffmpeg version and configuration :
  

  If the answer to my problem is to add some configuration setting to my ffmpeg please explain how i go about doing that.

• ffmpeg and 7160 HD Capture card error, already set rtbufsize 2000M, still real time buffer too full

  21 septembre 2015, par todaf

  The 7160 Capture card original video was shown fine in the Honestech HD DVR software that is included.

  However, when the card was captured using ffmpeg and publish out. This error occurred after a while running ffmpeg :

  real-time buffer [7160 HD Capture] video input too full or near too full ...

  I have already set -rtbufsize 2000M which is nearly the maximum that is allowed and can not be increased further.

  Please tell me how to resolve this bug or give me an example that can be used without producing this bug. Thank you very much. You do not neeed the code that I used because almost any code even the simplest code I used produced this error after running for a while. The published video also lag and lost.

• How can I generate a hls.m3u8 file using a youtube URL ?

  8 avril 2021, par User0011

  I used ffmpeg in python and I was able to generate a hls file from a local mp4 file that i had on my computer, but now I want to know if there is a way to generate the hls file using a youtube URL and give this url to the input() function of ffmpeg in python ?
Here is the code I used for the first time, I want to replace test.mp4 with a youtube URL, is it possible ?
Thanks for the help

  


  import ffmpeg_streaming
from ffmpeg_streaming import Formats, Bitrate, Representation, Size


video = ffmpeg_streaming.input('/Users/test.mp4')

_480p = Representation(Size(854, 480), Bitrate(750 * 1024, 192 * 1024))
_720p = Representation(Size(1280, 720), Bitrate(2048 * 1024, 320 * 1024))

hls = video.hls(Formats.h264(), hls_list_size=10, hls_time=5)
hls.representations(_480p, _720p)
hls.fragmented_mp4()
hls.output('/Users//hls.m3u8')
