Implementing Live Streaming Webinar Architecture - Need Guidance
21 septembre 2023, par vishnugplQuestion : 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 :


- 

-
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.


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


-
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.


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


-
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.

H264 HW Decoding on Android Using FFmpeg-10
21 septembre 2012, par limitfanI've noticed that ffmpeg has already included (libavcodec/libstagefright.cpp) and claimed to support H264's hardware decoding through StageFright framework. I've build the shared library according to (tools/build_libstagefright). But when doing real H264 frame decoding, it seems to be failed at Stagefright_init().
Does anybody succeed to use this new feature ? Thank you in advance. -
