• 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 ?

  


• How to create a full length video from images with FFmpeg ?

  14 avril 2021, par Lucas Naoki

  I have more than a thousand images that I want to transform into a 3 minutes video. I tried using this line ffmpeg -r 30 -i "E:/White-box-Cartoonization/test_code/cartoonized_images/$flower%03d.bmp" -c:v libx264 -pix_fmt yuv420p out.mp4 it worked but creates only a 5 seconds video. What do I need to do to turn it into a full length 3 minutes video ?

  7 août 2018, par Ali

  I have downloaded a Dynamic Adaptive Streaming over HTTP (DASH) via android DashDownloader class that is provided by exo player.

  SimpleCache cache = new SimpleCache(file.getAbsoluteFile(), new NoOpCacheEvictor());
  
  DefaultHttpDataSourceFactory factory = new DefaultHttpDataSourceFactory("ExoPlayer", null);
  
  DownloaderConstructorHelper constructorHelper = new DownloaderConstructorHelper(cache, factory);
  
  
  
  // Create a downloader for the first representation of the first adaptation set of the first
  
  // period.
  
  DashDownloader dashDownloader = new DashDownloader(Uri.parse(url), Collections.singletonList(new RepresentationKey(0, 0, 0)), constructorHelper);
  
  dashDownloader.download();

  Above code save many chunk .exo files into provided directory, How can i convert this files to single mp4 file ?
