Segmentation fault (core dumped)

CivilizedGuide commented 2 years ago

Hi, I have a problem trying to use libfreenect, especially when I try to use ./Protonect, it shows me the following error

[Error] [VaapiFrame] vaGetImage(display, surface, 0, 0, image.width, image.height, image.image_id): unknown libva error
Segmentation fault (core dumped)

my operating system is ubuntu 20.04 and i have an intel hd graphics 520

I do not have much knowledge in programming so I have not solved this problem

Sorry if you don't make me understand, I'm using a translator

I have the same issue. In my case, this is the output of ./bin/Protonect:

Same output using cpu or gpu options. The only one that doesn't not show the error immediately is ./bin/Protonect cl And shows [Error] [DepthPacketStreamParser] Packet buffer is NULL

I ll test the sensor on another pc. Just to make sure it is not the root of the problem.

Tried with another USB cable. Same error. I checked my graphic card info using:

userk@histamine:~/development/catkin_ws_ros_one$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Skylake GT2 [HD Graphics 520] (rev 07)

Then export LIBVA_DRIVER_NAME=i965 to match the Intel graphics driver as suggested by @xlz in this issue

Thanks

OpenKinect / libfreenect2
