Issue Description
Hello, i need help with running the replayer tool. Im trying to visualize recordings from two lidars which where taken with the recorder tool. The replayer tool starts it shows the window with the vehicle, but no pointcloud are visualized (screenshot). The recorded data is fine when i run it with sample_lidar_replay. The sample goes into segmentation fault after a few seconds of running and it prints a lot of warnings something about LidarAccumulator.cpp which im not sure where it is located or even if it is public.
Im running the tool with this command:
__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia __NV_PRIME_RENDER_OFFLOAD_PROVIDER=NVIDIA-G0 /usr/local/driveworks/tools/replayer/replayer --rig=/home/gabrhelik/nvidia/rig_2lidar_recorded.json
before the replayer i had to put these command because my OpenGL context is on the integrated GPU and it would not work without them.
In the rig i define a vehicle for just the purpose of running the tool. So the values are random.
Error String
