• Unable to download a file using youtube_dl

  22 octobre 2020, par perkymaster

  I am trying to play music from a bot using ffmpeg and youtube_dl by making using of discord.py but it seems that I am unable to download the file

  


  Here is my code :

  


  voice = get(client.voice_clients, guild=ctx.guild)

ydl_opts={
    'format': 'bestaudio/best',
    'noplaylist': 'True',
    'postprocessors': [{
        'key': 'FFmpegExtractAudio',
        'preferredcodec':'mp3',
        'preferredquality':'192',
    }],
}

with youtube_dl.YoutubeDL(ydl_opts) as ydl:
    print("Downloading audio now \n")
    ydl.download([url])

for file in os.listdir("./"):
    if file.endswith(".mp3"):
        name=file
        print(f"Renamed File: {file}\n")
        os.rename(file, "song.mp3")

voice.play(discord.FFmpegPCMAudio('song.mp3'), after=lambda e: print(f"{name} has finished playing"))
voice.is_playing()
voice.source=discord.PCMVolumeTransformer(voice.source)
voice.source.volume= 0.7

nname = name.rsplit("-", 2)
await ctx.send(f"Playing {nname}")
print("Playing \n")


  


  Nothing seems to happen, the bot is not playing any music.

  


  I am new to this, can anyone help ?

  


• Download encrypted TS files from video stream

  8 janvier 2021, par albertma789

  Following this post, I usually download transport stream (.ts) files by using the browser's developer console to find the URLs of the .ts files and then I use wget to download them. After that I use the ffmpeg -f concat method to combine them into an mp4 file.

  



  Recently I come across a site that streams videos and I used the same method to download all the .ts files. The site is here. After I downloaded all the individual .ts files, I use ffmprobe to check the file format but realized the .ts files cannot be understood by ffmpeg/ffmprobe. While the site uses http (not https) I thought the streams are not encrypted so I tried to open the .ts file in an hex editor but I don't know what format it is (but they don't look like zip/gz). My question is : are the transport steams encrypted ? If yes, is there a way to decrypt them ? If not ? Can anyone point me to the right direction such that I can make ffmpeg understand them ?

  



  An example transport stream (first & second) are here and here but the link might expire in a bit. In that case you will need to open the site in developer console to find the updated link to the .ts files.

  



  The site uses JW Player 8.0.0
