Replay

How to replay bug?

1. webrtc streaming
2. webrtc playback
3. Repeat the above two steps multiple times

Expected Behavior

Expected Behavior

Describe your expectation Multiple successful WebRTC streaming and playback without any failures occurring.

TRANS_BY_GPT3

[phusinh]

Do you know how to configure webrtc through the quic can you guide me?

[winlinvip]

Repeated multiple times, is the interval between pushing and pulling streams very short? After a pull stream fails, does the retry recover?

TRANS_BY_GPT3

[cppmediaman]

On average, there is a push-pull stream every minute, with around 40 channels each time. With this testing method repeated 30 times, there will be more than ten failures, resulting in an error rate of 0.7% to 0.9%.

TRANS_BY_GPT3

[winlinvip]

The frequency is not high, there will be no critical condition.

Can it be recovered by retrying after failure?

This needs to be thoroughly investigated to know.
