WebRTC: Frequently crash when using WebRTC (TCP)

[winlinvip]

I believe this bug could caused from issues with the signaling connection and the media connection, as they use separate TCP connections. This could lead to crashes due to the interaction between these two components on the server.

Identifying a simpler method to reproduce the issue is crucial; if we can reliably replicate the problem, we can address it directly. Conversely, without a way to stably reproduce it, finding a solution becomes much more challenging due to the need to guess.

We recognize the risks associated with using TCP for WebRTC. We are exploring enhanced solutions, similar to the smart pointer concept in C++11. However, at present, there is no definitive solution or 'silver bullet' for this issue. Thus, the most effective strategy remains to reproduce the issue so we can address it directly.

Hi, based on previous testing...

1. start playing 20*WebRTC Streams (can be different stream names) in 1 page
2. refresh this page for 2~3 times, must encuonter SRS crash issue
   that's most efficient way to reproduce the issue,

if 1 page only plays 1 webrtc stream, have to refresh lots of times and not absolutely trigger the bug

It would be beneficial if you could simplify the reproduction steps. Starting 20 players to reproduce the problem could be very complex. Perhaps, using network conditioning tools to introduce loss or delay in the network could allow the issue to be reproduced with just one or two players. Please try to reproduce it by using a publisher, for example. With the network condition tools, you might manage to reproduce it with only one publisher or possibly two.

I prefer using the publisher to reproduce the issue because using a player always requires a publisher as well, introducing complexity with two components involved. By reproducing the issue directly through a publisher, there's no need for a player, making the process simpler.
