Is it possible to seek through streamed youtube audio with discord.py (play from a given timestamp in the video)?

Unfortunately passing in a URL with a &t= tag does not cause discord.py's VoiceClient to start playing at that timestamp. I'm using youtube_dl.

Is is possible to seek through audio within discord.py in order to start streaming a YouTube video from somewhere besides the start?

I know some professional bots like Groovy have seek commands for streamed YouTube videos, so the Discord API itself is capable of this.

The code I'm using is from here.

discord.py youtube-dl ffmpeg python

In the ffmpeg_options, you're able to seek to a specific timestamp with the use of the -ss flag.

This is just how the options should look if you wish to start from, for example, 40 seconds:

ffmpeg_options = {
    'options': '-vn -ss 40'
}

And of course you can add an optional variable to the stream command:

import typing # for the optional argument of the timestamp

    @classmethod
    async def from_url(cls, url, *, loop=None, stream=False, timestamp=0):
        # moved the options from outside the class to inside the method.
        # this allows the use of variables in the options
        ffmpeg_options = {
            'options': f'-vn -ss {timestamp}'
        }
        # rest of the from_url code

    @commands.command()
    async def stream(self, ctx, timestamp: typing.Optional[int]=0, *, url): # add the arg
        """Streams from a url (same as yt, but doesn't predownload)"""

        async with ctx.typing():
            player = await YTDLSource.from_url(url, loop=self.bot.loop, stream=True, timestamp=timestamp)
            # other code

I only added in the code that I edited from the music bot example, so I hope it's clear what I edited. If any further clarification is needed/how something works, then I'll be happy to make edits.
