• avdevice/decklink : Add support for EIA-708 output over SDI

  7 septembre 2018, par Devin Heitmueller

  avdevice/decklink : Add support for EIA-708 output over SDI
  Hook in libklvanc and use it for output of EIA-708 captions over
  
  SDI.  The bulk of this patch is just general support for ancillary
  
  data for the Decklink SDI module - the real work for construction
  
  of the EIA-708 CDP and VANC line construction is done by libklvanc.
  Libklvanc can be found at : https://github.com/stoth68000/libklvanc
  Updated to reflect feedback from Marton Balint <cus@passwd.hu>,
  
  Carl Eugen Hoyos <ceffmpeg@gmail.com>, Aaron Levinson

• discord.py bot doesn't play music

  29 août 2022, par bon ho

  I'm making music bot with discord.py, but bot doesn't play music. The code doesn't send error message.

  


  my code :

  


  @tree.command(name="play", description="play music")
async def playmusic(interaction:Interaction,url_title:str,playfirst:bool=False):
  await interaction.response.send_message("I'm looking for music!!")
  guild=str(interaction.guild.id)
  try:
    queue[guild]
  except KeyError:
    queue[guild]=[]
  if interaction.user.voice is None:
    await interaction.edit_original_response(content="you must join any voice channel")
  else:
    voice_client: discord.VoiceClient = discord.utils.get(client.voice_clients, guild=interaction.guild)
    if voice_client == None:
      await interaction.user.voice.channel.connect()
      voice_client: discord.VoiceClient = discord.utils.get(client.voice_clients, guild=interaction.guild)
    player = await YTDLSource.from_url(url_title, loop=None)
    if playfirst and len(queue[guild])>1:
      queue[guild].insert(1,player)
    else:
      queue[guild].append(player)
    if not voice_client.is_playing():
      voice_client.play(player,after=None)
      await interaction.edit_original_response(content=f"{player.title} playing!!")
    else:
      await interaction.edit_original_response(content=f"{player.title} enqueued!")
    await asyncio.sleep(7)
    await interaction.delete_original_response()


  


  output :

  


  [INFO    ] discord.player: ffmpeg process 12 successfully terminated with return code of -11.


  


  What should I do ?

  


  version :

  


  discord.py 2.0.0 python 3.10.6
