• Some download errors in my discrod musicbot

  24 avril 2021, par takugrano

  I am making my music bot for discord
but i am having some problem with uploading videos

  


   @client.command()
async def play(ctx, url : str):
    song_there=os.path.isfile("song.mp3")
    try:
        if song_there:
            os.remove("song.mp3")
    except PermissionError:
        await   ctx.send("music is playing right now, use !stop command")
        return
    voiceChannel=discord.utils.get(ctx.guild.voice_channels,name='General')
    await voiceChannel.connect()
    voice=discord.utils.get(client.voice_clients,guild=ctx.guild)



    ydl_opts={
        'format':'bestaudio/best',
        'postprocessors':[{
                  'key':'FFmpegExtractAudio',
                  'preferredcodec':'mp3',
                  'preferredquality': '192',
              }],
    }
    with youtube_dl.YoutubeDL(ydl_opts)as ydl:
        ydl.download([url])
    for file in os.listdir("./"):
        if file.endswith(".mp3"):
            os.rename(file,"song.mp3")
    voice.play(discord.FFmpegPCMAudio("song.mp3"))


  


  in my programm I have more code but it is not that important.
After compile i have this :

  


  [youtube] 5RGaoLpBASw: Downloading webpage
[download] Destination: F1 Tokyo Drift-5RGaoLpBASw.m4a
[download] 100% of 1.11MiB in 00:00                  
[ffmpeg] Correcting container in "F1 Tokyo Drift-5RGaoLpBASw.m4a"
    ERROR: 
    Ignoring exception in command play:


  


  and this :

  


  raise FFmpegPostProcessorError(msg)
youtube_dl.postprocessor.ffmpeg.FFmpegPostProcessorError


  


  and this :

  


  raise DownloadError(message, exc_info)
youtube_dl.utils.DownloadError: ERROR: 


  


  and finally this :

  


  raise CommandInvokeError(exc) from exc
discord.ext.commands.errors.CommandInvokeError: Command raised an exception: DownloadError: ERROR: 


  


  but on my discord server nothing but connecting the bot to the channel happens
however, a file with the .m4a extension appears in the programm directory, which I need to play.

  


  how can i fix these errors ?

  


• Download m3u8 segments with ffmpeg without writing the .ts files to disk

  22 avril 2021, par O R

  I am trying to download m3u8 segments from an HLS live stream with ffmpeg without writing the .ts files to disk. I intend to run opencv on the image data in real time. Here is what I have tried, but I am only able to get one segment at a time and don't know how to just keep it in memory without writing to disk. When inspecting the network requests using developer tools on the Twitch site, I see the m3u8's arriving in real time, although, these don't work in the script. I have to refresh the page and get the URL of the first request that arrives, which is a URL not ending in .m3u8 (the one i'm using in the script)

  


  import requests
import m3u8

url = 'https://usher.ttvnw.net/api/channel/hls/gernaderjake.m3u8?allow_source=true&fast_bread=true&p=4466372&play_session_id=d66db58de3bf6be70a5f5824bbb72763&player_backend=mediaplayer&playlist_include_framerate=true&reassignments_supported=true&sig=2b97079328898fdae56b041616be6fc7b01bd13c&supported_codecs=avc1&token=%7B%22adblock%22%3Afalse%2C%22authorization%22%3A%7B%22forbidden%22%3Afalse%2C%22reason%22%3A%22%22%7D%2C%22blackout_enabled%22%3Afalse%2C%22channel%22%3A%22gernaderjake%22%2C%22channel_id%22%3A1423946%2C%22chansub%22%3A%7B%22restricted_bitrates%22%3A%5B%5D%2C%22view_until%22%3A1924905600%7D%2C%22ci_gb%22%3Afalse%2C%22geoblock_reason%22%3A%22%22%2C%22device_id%22%3A%22ec6cb1f95615ed0b%22%2C%22expires%22%3A1618772589%2C%22extended_history_allowed%22%3Afalse%2C%22game%22%3A%22%22%2C%22hide_ads%22%3Afalse%2C%22https_required%22%3Atrue%2C%22mature%22%3Afalse%2C%22partner%22%3Afalse%2C%22platform%22%3A%22web%22%2C%22player_type%22%3A%22site%22%2C%22private%22%3A%7B%22allowed_to_view%22%3Atrue%7D%2C%22privileged%22%3Afalse%2C%22role%22%3A%22%22%2C%22server_ads%22%3Afalse%2C%22show_ads%22%3Atrue%2C%22subscriber%22%3Afalse%2C%22turbo%22%3Afalse%2C%22user_id%22%3Anull%2C%22user_ip%22%3A%22173.22.40.125%22%2C%22version%22%3A2%7D&cdm=wv&player_version=1.3.0'

• How to download a video from m3u8 with aes-128, IV with FFMPEG ? [closed]

  13 avril 2021, par AWrr

  I've tried with a tutorial that prompted me to download the m3u8 file and then stream it with vlc but that didn't work. It just created a 160 bytes .mp4 file that couldn't be played.

  


  When I opened it, it contains a line in the form of :

  


  #EXT-X-KEY:METHOD=AES-128,URI="license://G",IV=0x08

  


  I've read some threads talking aboout a .key file, but this one doesn't have a .key in the "URI=" section and I don't really knoe how to get one, if I needed it.

  


  Will ffmpeg -i playlist.m3u8 -c copy -bsf:a aac_adtstoasc output.mkv work just fine ?

  


  Edit : I've tried it and it showed this :

  


  At the start
 Unable to open key file

  


  At the end
