• Combine .dash video and audio segments to .mp4

  11 décembre 2019, par Mike Stevens

  I was able to download some dash video segments (youtube-dl was apparently blocked from downloading the .mpd and just downloading, concatenating as normal) and was hoping to combine/concatenate them so I could watch in VLC, perhaps using ffmpeg. I was able to download the relevant .mpd and .ismc files, so I have all of the DASH video and audio segments, as well as the .mpd and .ismc downloaded and in one folder.

  The video files are labelled as such

  video=869000.dash
  
  video=869000-0.dash
  
  video=869000-600.dash
  
  video=869000-1200.dash

  and the audio in a similar fashion

  audio=96000.dash
  
  audio=96000-0.dash
  
  audio=96000-96225.dash

  Would anyone know of a way to combine all of these into one watchable video file ? AdobeHDS used to work great for combining fragments, and youtube-dl cleary has some sort of method to do it, but neither works with this particular .mpd. I don’t believe concatenate in ffmpeg will work, when I try to do that, it initializes the first .dash file (audio or video), but stops there.

  When I try to put the .mpd file through ffmpeg, it returns "Failed to open an initialization section in playlist 0". I would’ve assumed this initialization was the video=869000.dash file though (which is the one segment file that ffmpeg does recognize) ?

• discord.py Heroku FFmpeg issue

  6 avril 2022, par No.BoD

  hi I'm trying to deploy a discord bot on heroku. i'm using ffmpeg to stream music to a voice channel. i tried it local on my windows and got it working but when I deployed it on heroku, throws this exception and says nothing !

  


  I use these buildpacks :

  


  

  1. heroku/python

  


  2. https://github.com/jonathanong/heroku-buildpack-ffmpeg-latest.git

  


  


  I appreciate if someone can help
  
here's a sample code :

  


  vid = pafy.new("https://www.youtube.com/watch?v=gdL7s0kw0SM")
print("Pafy Vid Created!")
audio = vid.getbestaudio()
print("Pafy Audio Created!")
try:
    // self.FFMPEG_OPTIONS = {'before_options': '-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5', 'options': '-vn'}
    self.vc[ctx.guild.id].play(FFmpegPCMAudio(Song['source'], **self.FFMPEG_OPTIONS), after=lambda _: E.set())
    print("Playing Music!!!")
except Exception as ex:
    print(ex)


  


  and here's what I got :
