Replay (重现)

1. Open the website (my personal Alibaba Cloud, deployed with SRS) https://www.sayhelloworld.cn:8081/players/rtc_publisher.html 2. Push RTC stream webrtc://www.sayhelloworld.cn/live/livestream 3. Open VLC player
(At this time, you can play normally using https://www.sayhelloworld.cn:8081/players/rtc_player.html) rtmp://www.sayhelloworld.cn/live/livestream VLC player error, unable to play

Expect (Expected Behavior) Normal playback

Tried it out, there is a chance of 5.0 appearing.

ffplay normal: ffplay rtmp://localhost/live/livestream

H5 playback of HTTP-FLV is normal: http://localhost:8080/players/srs_player.html?schema=http

Playing FLV with VLC is also normal: http://localhost:8080/live/livestream.flv

Playing RTMP with VLC results in a black screen: rtmp://localhost/live/livestream

@winlinvip So is this a problem only in version 5.0? Should I downgrade my SRS version?

You try 4.0, I only tried 5.0 and there is a chance of it appearing.
