It seems like YouTube links expire? I don't really know but I need to fix this issue. This is my code:
class YTDLSource(discord.PCMVolumeTransformer):
def __init__(self, source, *, data, requester):
super().__init__(source)
self.requester = requester
self.title = data['title']
self.description = data['description']
self.uploader = data['uploader']
self.duration = data['duration']
self.web_url = data['webpage_url']
self.thumbnail = data['thumbnail']
def __getitem__(self, item: str):
return self.__getattribute__(item)
#classmethod
async def create_source(cls, ctx, player, search: str, *, loop, download=True):
async with ctx.typing():
loop = loop or asyncio.get_event_loop()
to_run = partial(ytdl.extract_info, url=search, download=download)
raw_data = await loop.run_in_executor(None, to_run)
if 'entries' in raw_data:
# take first item from a playlist
if len(raw_data['entries']) == 1:
data = raw_data['entries'][0]
else:
data = raw_data['entries']
#loops entries to grab each video_url
total_duration = 0
try:
for i in data:
webpage = i['webpage_url']
title = i['title']
description = i['description']
uploader = i['uploader']
duration = i['duration']
thumbnail = i['thumbnail']
total_duration += duration
if download:
source = ytdl.prepare_filename(i)
source = cls(discord.FFmpegPCMAudio(source), data=i, requester=ctx.author)
else:
source = {'webpage_url': webpage, 'requester': ctx.author, 'title': title, 'uploader': uploader, 'description': description, 'duration': duration, 'thumbnail': thumbnail}
player.queue.append(source)
except Exception as e:
print(e)
return
embed=discord.Embed(title="Playlist", description="Queued", color=0x30a4fb, timestamp=datetime.now(timezone.utc))
embed.set_author(name=ctx.author.display_name, icon_url=ctx.author.avatar_url)
embed.set_thumbnail(url=data[0]['thumbnail'])
embed.add_field(name=raw_data['title'], value=f"{len(data)} videos queued.", inline=True)
embed.set_footer(text=raw_data["uploader"] + ' - ' + '{0[0]}m {0[1]}s'.format(divmod(total_duration, 60)))
await ctx.send(embed=embed)
return
embed=discord.Embed(title="Playlist", description="Queued", color=0x30a4fb, timestamp=datetime.now(timezone.utc))
embed.set_author(name=ctx.author.display_name, icon_url=ctx.author.avatar_url)
embed.set_thumbnail(url=data['thumbnail'])
embed.add_field(name=data['title'], value=(data["description"][:72] + (data["description"][72:] and '...')), inline=True)
embed.set_footer(text=data["uploader"] + ' - ' + '{0[0]}m {0[1]}s'.format(divmod(data["duration"], 60)))
await ctx.send(embed=embed)
if download:
source = ytdl.prepare_filename(data)
else:
source = {'webpage_url': data['webpage_url'], 'requester': ctx.author, 'title': data['title'], 'uploader': data['uploader'], 'description': data['description'], 'duration': data['duration'], 'thumbnail': data['thumbnail']}
player.queue.append(source)
return
source = cls(discord.FFmpegPCMAudio(source), data=data, requester=ctx.author)
player.queue.append(source)
#classmethod
async def regather_stream(cls, data, *, loop):
loop = loop or asyncio.get_event_loop()
requester = data['requester']
to_run = partial(ytdl.extract_info, url=data['webpage_url'], download=True)
data = await loop.run_in_executor(None, to_run)
return(cls(discord.FFmpegPCMAudio(data['url']), data=data, requester=requester))
I'm using the rewrite branch of discord.py for the bot.
I'm not sure if I need to provide more details? Please let me know, I really need to get this fixed...

Answer 1

In fact it isn't really a problem with your code (and many people complain of this error).
This is just a possible issue when streaming a video. If you absolutely want to stream it, you have to accept this as a potential issue. Note how (almost) every music bots set limitations for the video/music you want to listen to.
If you need to ensure you do not get this issue, you have to fully download the music. (Which will also make the bot loading longer before playing).

Answer 2

Would you be able to post all your code? i may have a solution for you if i was able to see the whole code.
the solution i would recomend is to download the soong and then delete it after.
You could set your download to true and then add this in your player_loop
try:
# We are no longer playing this song...so, lets delete it!
with YoutubeDL(ytdlopts) as ydl:
info = ydl.extract_info(source.web_url, download=False)
filename = ydl.prepare_filename(info)
try:
if os.path.exists(filename):
os.remove(filename)
else:
pass
except Exception as E:
print(E)
await self.np.delete()
except discord.HTTPException:
pass
bit botched but could be cleaned up, this was the best solution i have found for me.
