v27.0.0.85. I have the HEVC codec installed on the machine and have confirmed that it can playback a local file using media player.

I can send h.264 SRT stream to vMix without issues but when I send h.265 I get this error ....

error: failed to configure output type. SRT listener.Decode Thread

I successfully stream h.265 from this same camera source to other end points without problems but for some reason vMix is failing. Any ideas?

What version of Windows are you on? Did you buy the $1 HEVC decoding license from the Windows Store?

Yes. Purchased, installed and confirmed HEVC playback via local video file on machine.

Win10 Pro

Ok, good. Under Settings -> Performance, do you have more than one option? It's possible, if you have both on-board graphics and a GPU, it could be doing something weird. If so, you may want to go into the nVidia control panel and "pin" vMix to use that GPU exclusively.

Only a Tesla T4 option.

I found a NVIDIA menu to "manage 3D settings" that 20+ different features (Antialiasing, CUDA GPUs, Overlay enable, etc) can be specified for vMix. Any idea what setting(s) might need to be tweaked?

Thanks!

Since this is related to HEVC decoding. I would start with any kind of encode/decode stuff (like nVenc)
