• 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

  pngdec : Stop trying to decode once inflate returns Z_STREAM_END
  If the input buffer contains more data after the deflate stream,
  
  the loop previously left running infinitely, with inflate returning
  
  Z_STREAM_END.

• ffmpeg : avcodec_open2 returns invalid argument

  26 octobre 2020, par roari

  I'm reusing the sample code from the developer 64-bit release of FFmpeg in my application to encode a video :

  


  AVCodec* pCodec_{nullptr};
AVCodecContext* pContext_{nullptr};

avcodec_register_all();
pCodec_ = avcodec_find_encoder(AV_CODEC_ID_MPEG2VIDEO);
if (!pCodec_) {}

pContext_ = avcodec_alloc_context3(pCodec_);
if (!pContext_) {}

pContext_->bit_rate = 400000;
pContext_->width = size.width();
pContext_->height = size.height();

pContext_->time_base.den = 1;
pContext_->time_base.num = fps;

pContext_->gop_size = 10;
pContext_->max_b_frames = 1;
pContext_->pix_fmt = AV_PIX_FMT_BGR0;

if (codec_id == AV_CODEC_ID_H264) {
    av_opt_set(pContext_->priv_data, "preset", "slow", 0);
}

int err = avcodec_open2(pContext_, pCodec_, nullptr);
if (err < 0) {}


  


  AVCodec* and AVCodecContext* look like they are allocated correctly. avcodec_open2 then returns invalid argument (-22).

  


  I use : Windows 10 64, VS2013 Compiler, Qt Creator IDE, ffmpeg(2016-05-12) 64bit.

  


  The sample I took the code from is decoding_encoding.c.

  


  Any ideas ?
