• Python Discord Music Bot : Playing next song while current song is playing

  8 février, par Deltrac

  I've been working on a Discord bot and got it working 90% of the time. On some occasions, the bot will be playing a song and it will stop playing and just move to the next song. My assumption is that it's because of how I am handling my play command and the play_next command as well.

  


  I've tried to re-arrange the code, change functionality, etc. without success.

  


  Here are the two commands :

  


  @client.command(name="p")
async def play(ctx, *, search_query: str):
        global bot_disconnect
        try:
        # Only start a song if the user trying to play a song is in a voice channel
            if ctx.author.voice:
                voice_channel = ctx.author.voice.channel
                voice_client = await voice_channel.connect() # Find who played the song and have the bot enter that channel
                voice_clients[voice_client.guild.id] = voice_client
            else:
                await ctx.channel.send("Get in a voice channel")
                return
        except Exception as e:
                print(e)
        try:
            if is_youtube_url(search_query):
                loop = asyncio.get_event_loop() # Let's the bot multi-task (Similar behavior to interrupts in C/C++)
                data = await loop.run_in_executor(None, lambda: ytdl.extract_info(search_query, download = False))
                video_url = data["webpage_url"] # Save the youtube video URL to variable
                song_url = data["url"] # Save the extracted URL to a variable
                title = data["title"]
            else:
                url = f"ytsearch:{search_query}"
                loop = asyncio.get_event_loop() # Let's the bot multi-task (Similar behavior to interrupts in C/C++)
                data = await loop.run_in_executor(None, lambda: ytdl.extract_info(url, download = False)) 
                entry = data['entries'][0]
                video_url = entry["webpage_url"] # Save the youtube video URL to variable
                song_url = entry["url"] # Save the extracted URL to a variable
                title = entry["title"]

            if ctx.guild.id in voice_clients and voice_clients[ctx.guild.id].is_playing():
                await queue(ctx, search_query = video_url, title = title)
            else:
                player = discord.FFmpegOpusAudio(song_url, **ffmpeg_options) # THIS IS WHAT PLAYS THE ACTUAL SONG!!!!!!
                await ctx.channel.send(f"Now Playing: {video_url} \n[DOWNLOAD LINK HERE]({song_url})") # Send the video URL to discord channel and include a download link as well
                bot_disconnect = False
                voice_clients[ctx.guild.id].play(player, after=lambda e: asyncio.run_coroutine_threadsafe(play_next(ctx), client.loop))
        except Exception as e:
                print(e)



async def play_next(ctx):
    if len(queues) != 0 and queues.get(ctx.guild.id):         
        search_query = queues[ctx.guild.id].pop(0)[0] # Pull the URL from the next index
        loop = asyncio.get_event_loop() # Let's the bot multi-task (Similar behavior to interrupts in C/C++)
        print(f"{search_query}")
        data = await loop.run_in_executor(None, lambda: ytdl.extract_info(search_query, download = False))
        player = discord.FFmpegOpusAudio(data["url"], **ffmpeg_options)
        voice_client = voice_clients[ctx.guild.id]
        voice_client.play(player, after=lambda e: asyncio.run_coroutine_threadsafe(play_next(ctx), client.loop))
        await ctx.channel.send(f"Now Playing: {data['webpage_url']} \n[DOWNLOAD LINK HERE]({data['url']})") # Send the video URL to discord channel and include a download link as well
    else:
        await ctx.send("No songs in queue")


  


  I can also link the full code, if required.

  


• Converting a color video to 8-bit (per frame) video via FFMPEG

  25 mai 2020, par SilverSurfer

  I wish to convert a color video file (AVI format) to grayscale video (i.e. 8 bits per frame) AVI video via FFMPEG. Any pointers ?

  



  I have tried using gray and yuv420p options in pix_fmt but it they didn't help.

  



  Thank you
