是否可以使用 discord.py(从视频中的给定时间戳播放)搜索流式 youtube 音频?

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

如果您希望从例如 40 秒开始，这就是选项的外观:

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

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

当然你可以在 stream 命令中添加一个可选变量:

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

我只添加了我从音乐机器人示例编辑的代码，所以我希望我编辑的内容很清楚.如果需要任何进一步的说明/某些东西是如何工作的，那么我很乐意进行编辑.

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.
