Does Wowza support the latest 4090 Nvidia cards? I tried both in windows server 2019 and Ubuntu LTE 22.04 LTE.

Scenario (2 Identical HLS stream) as input & need to transrate them into multiple bit rate.  
the first stream works but the second stream doesn’t do as expected.

What could be the issue?

I see that same issue was posted back in 2020 but solution wasn’t posted yet.

@Karthik_Alagappan

To further progress on why the 2nd stream is not working, I do recommend opening a support ticket for review by our Wowza Support Engineers.  
[https://support.wowza.com/hc/en-us](https://support.wowza.com/hc/en-us)

Files that will be needed from the Wowza install directory:  
[install-dir]/conf  
[install-dir]/transcoder  
[install-dir]/logs (only latest logs are needed showing a Wowza restart and 2nd stream not working)

it was due to customer transcoder. the issue is resolved when we replaced the hardware.
