Replay

Please describe how to replay the bug?

Step 1: push to rtmp stream using OBS with AMD HW h.264 encoding

push to srs using OBS GUI

Step 2: watch the stream using MPC-HC or mpv

open url rtmp://xxxx/xxxx/xxxx in the player

Expect

Please describe your expectation.

Live stream shows on the player

Actual results

Failed to play and error on srs log (see above)

The "dh generate key" error is produced by OpenSSL. Is this a randomly occurring bug, or is there a consistent and reliable method to reproduce it? Could you help to test SRS 5.0, as it utilizes a newer version of OpenSSL that might exhibit different behavior?

I can always reproduce the issue, not occasionally. I'll try 5.0.

Built tag v5.0-b1 with --generic-linux=on --srt=off. openssl version is 3.1.1.

I can confirm it works normally
