How to make restreamer work with hardware encoding/decodig cuda etc.

FilipStadler commented 1 year ago

I run restreamer on Linux, On WSL2 and RaspberryPI4 (Raspbian 32bit with gpu) but on the other I only use passtru to avoid GPU encoding but its a problem the cpu load is around 75% and sure it would be alot cooler if the hardware encoding was working for me.

But why is not working ?

I use GTX1660TI ( windows wsl2) and GTX1660 super with latest nvidia drivers on PopOS(Ubuntu 22.04)

OBS works fine and Davici resolve 18 can render video etc. but for some reason restreamer needs alot more to run with hardware gpu ?

For some reason it depends cuda something API but I am stuck because why is cuda needed by restreamer when other programs can do encoding/deconding ?

I need a guide on howto add the cuda support and possible simular for

Using nvidia-smi get something that says cuda 11.7

Simular nvidia-smi On my wsl2 it says Driver 516.94 also cuda 11.7

I did find a guide to install cuda (tool kit)

https://developer.nvidia.com/cuda-downloads?target_os=Linux&target_arch=x86_64&Distribution=Ubuntu&target_version=22.04&target_type=deb_local

After that i installed restreamer for nvidia and but is it possible that it only works with cuda 11.4 and not 11.7 ?

I get the following errors

Have anyone made hardware decoding/encoding work with succes ?

Hello Filip Thank you for your patience. We'll have a look ...

Hey @FilipStadler Maybe it's the CUDA version. We use 11.4, and you use 11.7. I will create a suitable image for you to test and let you know here.

Yes lets try because I have cuda 11.7 on two computers - a windows10 with wsl and a my normal ubuntu/popos. I did tried srt with hvec and the larix broadcaster and it was not working so i changed to h264 on the transmitting device and it was working so maybe this is also related to the problem. But it would surely be nice to have the gpu power working.

i am having the same issues with Cuda 11.7 (RTX 2080Ti with the 515 Driverset) on a linux machine. No matter which cuda option i choose for de-/coding it always throws the same error mentioned above

@jstabenow Any Updates on a test version with cuda 11.7?

Please check the latest datarhei/restreamer:cuda-latest image. It's now CUDA v11.7.1
