• Discord.py music_cog, bot joins channel but plays no sound

  20 juin 2021, par Ozzy

  I have started using python a week ago or so. I have watched all the related videos on YT and checked google pages etc. But still no luck. My bot perfectly joins to the voice channel and when i use play it downloads and presumebly starts the play function but there is no sound or anything, it just joins and waits 1-2 mins then leaves with timeout error.

  


  from discord.ext import commands
import logging

from youtube_dl import YoutubeDL

logging.basicConfig(level=logging.INFO)


class music_cog(commands.Cog):
    def __init__(self, bot):
        self.bot = bot

        # all the music related stuff
        self.is_playing = False

        # 2d array containing [song, channel]
        self.music_queue = []
        self.YDL_OPTIONS = {'format': 'bestaudio', 'noplaylist': 'True', 'no_warnings': 'False'}
        self.FFMPEG_OPTIONS = {'before_options': '-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5',
                               'options': '-vn'}

        self.vc = ""

    def search_yt(self, item):
        with YoutubeDL(self.YDL_OPTIONS) as ydl:
            try:
                info = ydl.extract_info("ytsearch:%s" % item, download=False)['entries'][0]
            except Exception:
                return False

        return {'source': info['formats'][0]['url'], 'title': info['title']}

    def play_next(self):
        if len(self.music_queue) > 0:
            self.is_playing = True

            # get the first url
            m_url = self.music_queue[0][0]['source']

            # remove the first element as you are currently playing it
            self.music_queue.pop(0)

            self.vc.play(discord.FFmpegPCMAudio(m_url, **self.FFMPEG_OPTIONS), after=lambda e: self.play_next())
        else:
            self.is_playing = False

    # infinite loop checking
    async def play_music(self):
        if len(self.music_queue) > 0:
            self.is_playing = True

            m_url = self.music_queue[0][0]['source']

            # try to connect to voice channel if you are not already connected

            if self.vc == "" or not self.vc.is_connected() or self.vc == None:
                self.vc = await self.music_queue[0][1].channel.connect()
            else:
                await self.vc.move_to(self.music_queue[0][1])

            print(self.music_queue)

            self.music_queue.pop(0)

            self.vc.play(discord.FFmpegPCMAudio(m_url, **self.FFMPEG_OPTIONS), after=lambda e: self.play_next())
        else:
            self.is_playing = False

    @commands.command(name="play", help="Plays a selected song from youtube")
    async def p(self, ctx, *args):
        query = " ".join(args)

        voice_channel = ctx.author.voice
        if voice_channel is None:
            # you need to be connected so that the bot knows where to go
            await ctx.send("Connect to a voice channel!")
        else:
            song = self.search_yt(query)
            if type(song) == type(True):
                await ctx.send(
                    "Could not download the song. Incorrect format try another keyword. This could be due to playlist or a livestream format.")
            else:
                await ctx.send("Song added to the queue")
                self.music_queue.append([song, voice_channel])

                if self.is_playing == False:
                    await self.play_music()

    @commands.command(name="queue", help="Displays the current songs in queue")
    async def q(self, ctx):
        retval = ""
        for i in range(0, len(self.music_queue)):
            retval += self.music_queue[i][0]['title'] + "\n"

        print(retval)
        if retval != "":
            await ctx.send(retval)
        else:
            await ctx.send("No music in queue")

    @commands.command(name="skip", help="Skips the current song being played")
    async def skip(self, ctx):
        if self.vc != "" and self.vc:
            self.vc.stop()
            await ctx.send("Stopped!")
            # try to play next in the queue if it exists
            await self.play_music()
            await ctx.send("Skipped!")


def setup(bot):
    bot.add_cog(music_cog(bot))


  


  I enabled logs to be sure, when it connects there's just that info :

  


  INFO:discord.voice_client:Connecting to voice... | INFO:discord.voice_client:Starting voice handshake... (connection attempt 1)

  


  I have also checked FFMPEG and its Path, tried different codes and methods but even though they work there is no sound. Also I installed discord.py[voice] too.

  


  I appreciate help already, thanks.

  


• HLS stream plays in VLC not in Safari

  7 janvier 2021, par Myles McDonnell

  I have created a HLS stream using FFMPEG using this command :

  


  ffmpeg -i 10-brass-in-pocket.flac -map 0:a -map 0:a -map 0:a -map 0:a -c:a:0 flac -c:a:1 aac -c:a:2 aac -c:a:3 aac -b:a:1 320k -b:a:2 160k -b:a:3 96k -f hls -hls_playlist_type vod -master_pl_name master.m3u8 -var_stream_map "a:0 a:1 a:2 a:3" stream_%v.m3u8

  


  see master playlist here : https://di5wym8npn4cm.cloudfront.net/ffmpeg/master.m3u8

  


  It has for sub-streams ;

  


  

  • 1 FLAC @ 44.1Hz / 16bit

  


  • 2 AAC-LC 320

  


  • 3 AAC-LC 160

  


  • 4 AAC-LC 96

  


  


  It works if I play that URL in VLC but if I use that URL in a HTML5 control and load in Safari the loader spins and I can see from the dev tools the data being pulled down but it doesn't play, see here : https://di5wym8npn4cm.cloudfront.net/ffmpeg/index.html

  


  Why doesn't this play in Safari and how can I debug this ?

  


• FFMPEG, player plays jerky video after encoding

  9 septembre 2020, par AKL

  I've been using FFMPEG on Windows 10 for a while. To help me do my job, I have got several DOS batch files which take parameters and perform tasks like cut from beginning, blur area, mute audio etc.

  


  I usually take big videos, extract the parts that I like using Avidemux, cut / apply filter on some parts using FFMPEG, join them using FFMPEG and then encode again to get rid of any errors (or jerkiness, etc) on my target player, which is Kodi 18.xx running on an Android TV (TCL brand).

  


  I have done a similar process for a video that I have been doing for several years and this video seems to be out of my control. I have chopped up the video using Avidemux 2.7.2. The video has been cut at key frames. If I take a single un-encoded file, it runs perfectly on my Android TV. If I encode it using FFMPEG, it starts to jerk when played on my Android TV.

  


  The videos always plays fine on VLC player running on my PC.

  


  Some information that may be helpful. I can attach detailed frame information if desired.

  Showing info for the source file. Codec is hevc, I think FFMPEG does not have default support for ?

  I would appreciate if someone can point to me where I am going wrong.

  


  The command used to perform the encoding is as follows (only the library was swapped between libx264 and lib265) :

  


  ffmpeg -i in.mp4 -map 0:v -c:v libx264 -video_track_timescale 24390 -crf 23 -map 0:a -c:a aac -copyts -vsync 0 -async 0 -movflags +faststart out.mp4


  


  P.S. My knowledge is more based on trial-and-error and I don't understand video formats (and concepts) much except for what got me to this point.
