• discord.py ffmpeg song plays too quickly at the beginning

  30 mai 2023, par C-Gian

  I built a discord bot using discord.py and ffmpeg, it works but the song in the first 0-5 seconds plays too fast, I think it's buffering so I tried to use asyncio.sleep but didn't work, suggestions to solve the problem ?

  


  play func :

  


  with youtube_dl.YoutubeDL(self.opts) as ydl:
    await asyncio.sleep(0.1)
    ydl.cache.remove()
    await asyncio.sleep(0.1)
    info = ydl.extract_info(url, download=False)
    raw_url_song = info['formats'][0]['url']
    await self.real_play(ctx, raw_url_song)


  


  real_play func :

  


  source = await discord.FFmpegOpusAudio.from_probe(processed_url_song, **self.FFMPEG_OPTIONS)
await asyncio.sleep(0.5)
self.vc.play(source, after=lambda e: asyncio.run_coroutine_threadsafe(self.real_play(ctx, processed_url_song), self.client.loop))


  


  these are the options :

  


  self.FFMPEG_OPTIONS = {'before_options': '-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5', 'options': '-vn'}
self.OPTIONS = {'format': 'bestaudio'}
self.opts = {'extract_flat': True, 'skip_download': True}


  


  the functions are separate because I do something else (such as playlists), I have reported only the essential code to understand the problem, and the cache remove is essential to reduce the occurence of HTTP 404 forbidden error, btw also without cache remove the problem persists

• Implementing Live Streaming Webinar Architecture - Need Guidance

  21 septembre 2023, par vishnugpl

  Question : I'm working on a project to implement a live streaming webinar platform, and I'm looking for guidance on the architecture and technologies to use. I have some specific requirements and constraints, and I'd appreciate any advice or pointers on how to get started.

  


  Context :
I'm tasked with building a live streaming webinar platform from scratch for our organization. Here are some key requirements and constraints :

  


  


  1. Live Video Streaming : We need to support live video streaming for
webinars, workshops, and conferences. Low latency is crucial for
real-time interaction between presenters and attendees.

     


  


  2. Scalability : The platform should be able to handle a large number of concurrent attendees, potentially thousands or more,
without compromising performance.

     


  


  3. Security : Security is a top priority. We need to ensure that only authorized users can access the webinars, and we must protect
against unauthorized recording or distribution of the content.

     


  


  4. User Interaction : Attendees should be able to ask questions, participate in polls, and interact with presenters in real-time.

     


  


  5. Recording and Playback : We also want to provide recorded versions of past webinars for on-demand viewing (HLS).

     


  


  


  Current Tech Stack :

  


  

  • Frontend : React

  


  • Backend : Node.js with Express

  


  • Database : MongoDB

  


  • Cloud Hosting : AWS

  


  


  Questions :

  


  


  • What technologies or services are best suited for handling live video streaming with low latency ?

    


  


  • How can I ensure scalability in terms of both video streaming and handling a large number of users ?

    


  


  • What security measures should I consider to protect the content and user data ?

    


  


  • Are there any recommended frameworks or libraries for building interactive features like real-time chat and polling ?

    


  


  • What's the best approach for recording and serving on-demand webinar content ?

    


  


  


  Additional Information :

  


  


  • Budget is a consideration, so cost-effective solutions are preferred.

    


  


  • Any open-source or third-party tools that can simplify development are welcome.

    


  


  • I have experience with AWS, but I'm open to other cloud providers if they offer advantages for this project.
