• ffmpeg can play video but not a stream containing the same data

  21 mai 2017, par Robbsen

  This is my first time encountering video codecs/video streaming.

  I am receiving raw h.264 packets over TCP. When I connect to the socket, listen to it and simply save the received data to a file, I am able to play it back using

  ffplay data.h264

  However, when I try to directly play it from the stream without saving it, using

  ffplay tcp://addr:port

  all I get is the error

  Invalid data found when processing input

  Why is that ?

• Discord theme songs

  29 septembre 2021, par SweLG

  I want to give some of my friends theme songs and I have been able to do it using the code below

  


  @commands.Cog.listener()
    async def on_voice_state_update(ctx, member, before, after):
        if member.name in theme_songs.keys():
            voice = await member.voice.channel.connect()
            voice.play(discord.FFmpegPCMAudio(source=f"theme_songs/{theme_songs[member.name]}"))


  


  The problem is the bot is activated every time something happens, i.e. muting, going live etc.
How could i make it so that it only looks for member joining ?

  


• How do I loop audio files in discord.py ?

  25 septembre 2021, par Jonah Alexander

  I cannot for the life of me find or figure out a solution that works anymore. here is both the bit of code that is actually important, and the whole file if you would like to see that too

  


      async def play(self, ctx: commands.Context, url, lp):
        channel = ctx.author.voice.channel

        if lp == 'loop':
            await channel.connect()

            async with ctx.typing():
                player = await YTDLSource.from_url(url, loop=self.bot.loop)
                ctx.voice_client.play(player, after=lambda e: print('Player error: %s' % e) if e else None)
            await ctx.send('Now playing: {}'.format(player.title))
            while True:
                if not ctx.voice_client.is_playing():
                    async with ctx.typing():
                        ctx.voice_client.play(player, after=lambda e: print('Player error: %s' % e) if e else None)
                time.sleep(0.5)
        else:
            async with ctx.typing():
                await channel.connect()
                player = await YTDLSource.from_url(url, loop=self.bot.loop)
                ctx.voice_client.play(player, after=lambda e: print('Player error: %s' % e) if e else None)
            await ctx.send('Now playing: {}'.format(player.title))

  is the code poorly made and/or badly organized ? probably. but this is a personal project and did not expect to be sharing this with anyone. If you need clarification on anything lmk.

  


  with the code here, the issue im getting is when I do the looped version, the bot disconnects for a frame and reconnects, then I get this error

  


  


  discord.ext.commands.errors.CommandInvokeError : Command raised an exception : ClientException : Not connected to voice.

  


  


  the bot does not disconnect immediately when not using the looped version, and trying to manually reconnect it at the start of the loop gives me an error saying it's already connected.

  


  also sidenote I did not write the YTDLSource class or the ytdl_format_options.
