• Youtube-dl : Download video with maximum FPS and change FPS using OpenCV

  8 mai 2021, par MmBaguette

  I'm trying to download a YouTube video using YouTube-dl and specifying a maximum FPS. I don't want the lowest FPS, but I also don't want an FPS higher than 30. The code below does not work, but it was my best attempt.

  


  ydl_opts = {
    'format': '(bestvideo[fps<30]/bestvideo)+bestaudio/best', # CHANGE FOR VIDEO
    'outtmpl': "youtube_video.%(ext)s",
}
print("Downloading YouTube video.")
                
with youtube_dl.YoutubeDL(ydl_opts) as ydl:
     ydl.download([text])


  


  If not, can I change the FPS of a video using OpenCV ? I tried using cap.set(cv2.CAP_PROP_FPS) but this doesn't work either.

  


  cap = cv2.VideoCapture(file)
fps = cap.get(cv2.CAP_PROP_FPS)
print(fps) # prints 60.0
cap.set(cv2.CAP_PROP_FPS)
fps = cap.get(cv2.CAP_PROP_FPS)
print(fps) # 60.0 again


  


• How to download videos from m3u8 that has sample-aes encryption [closed]

  8 mai 2021, par Rajat Bisht

  I am trying to download my online lecture from m3u8 link but it shows "ffmpeg do not support sample-aes yet".
Link of lecture : https://pw.pc.cdn.bitgravity.com/b7826d86-612d-4ef2-b17c-cc4f91d9584c/master.m3u8 .
It is sample-aes-ctr encrypted. Also I know python a little bit so it would be better if I could download it using python. Also I have link to mpd file : https://pw.pc.cdn.bitgravity.com/b7826d86-612d-4ef2-b17c-cc4f91d9584c/master.mpd.
Please can anyone tell any module or something which can help in downloading it.....
Thanks in advance.

  


• 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 ?
