Issue Description
Based on the code and actual testing, the librealsense compiled with BUILD_WITH_CUDA option does not fall back to a CPU implementations when a GPU is not available.
The selection of backend processing code is done using a #ifdef strategy in here:
https://github.com/IntelRealSense/librealsense/blob/5ff27fca5aaeec4736d6bb3bfb958fee82ee198b/src/proc/processing-blocks-factory.cpp#L13-L30
as opposed to performing a fallback if creating a CUDA context does not work.
Thanks so much @guillaumeautran for your PR. I have added an Enhancement tag to this case to indicate that it should be kept open whilst the PR that is associated with it is active. Thanks again!
Hi again @guillaumeautran As your PR at https://github.com/IntelRealSense/librealsense/pull/10086 did not pass build checks, would you like to take a look at it to see whether it can be fixed, please? Thanks!
Hi, sorry for the delay here. Yes, I will rebase and fix the PR in the coming weeks.
It's no problem at all, @guillaumeautran - thanks very much for the update!
