Unable to view RTMP stream when using a USB camera on Rpi with local ant media server setup

[Harshavardhan034]

I have set up a local ant media server (version: 2.6.4) and am trying to stream my USB camera feed using RTMP, however, all I can see is a black screen. I have attached the screenshot with the black screen and the log output as seen on the dashboard. I am kindly requesting assistance in this regard. Thanks, Harshavardhan

Thanks for the report. To reproduce it in our side can you record the RTMP output of your RPI to an mp4 file and share it with us?
