h.265 HEVC SRT input error

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?

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)

No luck with any of that optimization.
If I untick "Use Hardware Encoder" on the vMix input I do get an image displayed with h.265 but it's garbage and not decoding properly. Looks like it's missing a color channel and pixel information,

Thanks! Is your system local pc or in cloud? And if local you have another gpu for display? Because i see that this kind of GPU doesnt have outputs. Vmix doesnt suggest 2 gpu in same system,so maybe something happens there. Or look maybe for another gpu driver?

Looks like it's missing a color channel and pixel information, Well, garbage we can do something about. If you look in the Stats window in the SRT tab, if you're getting more than 25% packet loss (the default reserve bandwidth setting for SRT), try re-adding the source using a higher latency setting. I did a game where the 4G modems had more than 30% packet loss and bumping the latency up to 5000ms (yes, 5 seconds) totally fixed it.

It's an AWS EC2 g4dn.8xlarge

vMix reporting 0% packet loss. I tried upping the latency anyway. No change.

We tried some different drivers previously with no luck. The different drivers actually totally dorked the NiceDCV screen mirroring.
