• Code returns AttributeError : 'VoiceChannel' object has no attribute 'play' when running on Discloud

  18 septembre 2023, par Sc4rl3ttfir3

  So, my code works fine when I run it locally, but even after adapting it to run on Discloud, it returns an error I can't solve.

  


  Code :

  


  @bot.command(name='play', help='To play song')
async def play(ctx, url):
    voice_channel = ctx.author.voice.channel

    if voice_channel is None:
        return await ctx.send('You are not connected to a voice channel.')

    async with ctx.typing():
        filename = await YTDLSource.from_url(url, loop=bot.loop)
        
        if ctx.voice_client is not None:
            ctx.voice_client.stop()

        source = discord.FFmpegPCMAudio(
            executable="ffmpeg",
            source=filename
        )
        
        voice_channel.play(source)

    await ctx.send('**Now playing:** {}'.format(filename))


  


  When it runs on the Discloud server, it returns the following error/traceback message :

  


  Traceback (most recent call last):
File "/usr/local/lib/python3.11/site-packages/discord/ext/commands/core.py", line 235, in wrapped
ret = await coro(*args, **kwargs)
^^^^^^^^^^^^^^^^^^^^^^^^^^^
File "/home/user_686208406444572830/Sc4rl3ttb0t.py", line 357, in play 
voice_channel.play(source)
^^^^^^^^^^^^^^^^^^
AttributeError: 'VoiceChannel' object has no attribute 'play'


  


  Anybody with any idea of what is going wrong would be greatly appreciated for helping out

• How to process video stream ?

  27 avril 2016, par sharpener

  I would like to ask some experienced multimedia professional how to proceed with following task :

  Given URL provides video stream and we would like to get access to decoded frames (byte stream in memory) in managed Win7+ application (C#). We don’t want to render/present the frames the standard way. The video format is known but not fixed (might get changed between two successive sessions, but we will know the parameters).

  So far, I have found there are several methods and I have build following picture in my mind :

  1. ffmpeg wrapper
     • Pros
       1. Self contained (no dependency to windows technologies)
       2. Powerful
     • Cons
       1. Little more complex to understand
       2. Lot of different wrapping variants (FFmpeg.NET, ffmpeg-sharp, ffmpeg-shard, FFmpeg.AutoGen, ...)
  2. DirectShow wrapper
     • Pros
       1. Widely used/supported technology (variaous filters freely available)
       2. Nice/detailed documentation on MSDN
     • Cons
       1. Quite old
       2. Considered obsolete from the point of author’s view (available only for desktop model on runtime >= Win8)
  3. MediaFoundation wrapper
     • Pros
       1. Theoretical successor of DirectShow, so should be available in the future
     • Cons
       1. Seems to be not as good as DirectShow
       2. Not very popular, limited "community" support
  4. FFmpegInterop wrapper
     • Pros
       1. Microsoft’s open source wrapper alternative
     • Cons
       1. Not available for runtime < Win8
