• FFMPEG & YouTube Live - "Bad Video Settings" - Please use a keyframe frequency of four seconds or less

  28 janvier 2020, par John Doe

  Trying to live stream to YouTube and from my perspective, everything seems to be working fine. However YouTube keeps giving me the following message :

  Bad Video Settings

  Please use a keyframe frequency of four seconds or less. Currently, keyframes are not being sent often enough, which will cause buffering. The current keyframe frequency is 8.4 seconds. Note that ingestion errors can cause incorrect GOP (group of pictures) sizes.

  I’ve dug around for hours and so far nothing seems to be making any difference. I added -g 60 and as I didn’t fully understand I also tried adding -g 2 but neither worked. Here is the command I’m currently using :

  ffmpeg -re -f concat -safe 0 -i "concat.txt" -c copy -preset veryfast -maxrate 1200k -bufsize 2400k -framerate 30 -g 60 -f flv rtmp://a.rtmp.youtube.com/live2/XXXX-XXXX-XXXX-XXXX

• Python, Youtube-video-downloader-merger Can i inproove this script run faster ?

  31 janvier 2020, par robotiaga

  I created script which one downloading video and sound from Youtube, and after that merging sound and video with ffmpeg, i wondering is another way to make same result but in faster way ? Because this script takes about 7 min depends on Video quality and duration. My code bellow :

  from pytube import YouTube
  
  import sys
  
  import ffmpeg
  
  import os
  
  
  
  
  
  class Downloader(YouTube):
  
  
  
      def __init__(self, link):
  
          self.link = YouTube(link)
  
          self.hq = []
  
          self.best_video = []
  
          self.best_sound = []
  
  
  
  
  
      def stream_objects(self):
  
          q = [self.hq.append(x) for x in self.link.streams.all()]
  
          self.best_video.append(str(self.hq[1]).split()[1].split('\"')[1])
  
          self.best_sound.append(str(self.hq[-1]).split()[1].split('\"')[1])
  
          return self.best_video, self.best_sound
  
  
  
      def downloady(self):
  
          vid = self.link.streams.get_by_itag(str(self.best_video).strip("['']"))
  
          audio = self.link.streams.get_by_itag(str(self.best_sound).strip("['']"))
  
          self.vid_title = (f"{vid.title}"+".mp4")
  
  
  
          vid.download(filename='video')
  
          audio.download(filename='audio')
  
          print('Downloaded, Now Starting Merge \n\n\n\n\n')
  
          print(f'{self.vid_title}'+'\n')
  
  
  
      def merge(self):
  
          ffmpeg.output(ffmpeg.input('video.mp4'), ffmpeg.input('audio.webm'), self.vid_title).run()
  
          os.remove('video.mp4')
  
          os.remove('audio.webm')
  
  
  
  
  
  
  
  if __name__=='__main__':
  
      a = Downloader(link = sys.argv[1])
  
      a.stream_objects()
  
      a.downloady()
  
      a.merge()

  OKE UPDATE :
  Now code looks like that..Second problem is slow downloading mp4 files from YouTube server, i have 10Gb/s internet. Good connection with YT servers, but why so poor downloading ? ? ? :)

  from pytube import YouTube
  
  import sys
  
  import ffmpeg
  
  import os 
  
  import subprocess
  
  
  
  class Downloader(YouTube):
  
  
  
      def __init__(self, link):
  
          self.link = YouTube(link)
  
          self.hq = []
  
  
  
  
  
      def stream_objects(self):
  
          self.best = self.link.streams.filter(file_extension='mp4')
  
          q = [self.hq.append(x) for x in self.best.all()]
  
          self.best_vid_itag = str(self.best.all()[1]).split()[1].split('\"')[1]
  
          self.best_audio_itag = str(self.best.all()[-1]).split()[1].split('\"')[1]
  
  
  
      def downloader(self):
  
          vid = self.link.streams.get_by_itag(self.best_vid_itag)
  
          aud = self.link.streams.get_by_itag(self.best_audio_itag)
  
          print('Donwloading Video file...\n')
  
          vid.download(filename='video')
  
          print('Video file downloaded... Now Trying download Audio file..\n')
  
          aud.download(filename='audio')
  
          print('Audio file downloaded... Now Trying to merge audio and video files...\n')
  
  
  
      def merger(self):
  
          lin = str(self.link.title).rstrip()
  
          lin2 = (lin+'.mp4')
  
          subprocess.run(f'ffmpeg -i video.mp4 -i audio.mp4 -c copy "{lin2}"', shell=True)
  
          os.remove('video.mp4')
  
          os.remove('audio.mp4')
  
          print('Done....\n')
  
  
  
  if __name__=='__main__':
  
      a = Downloader(link = sys.argv[1])
  
      a.stream_objects()
  
      a.downloader()
  
      a.merger()
