is Raspberry pi 4 support?

[Jyurineko]

thx for amazing work,
but may i ask is Raspberry pi 4 support?
i follow the document and after "pip install pylibfreenect2"
it shows

i tried method in another issue like : export LD_LIBRARY_PATH=$HOME/freenect2/lib:$LD_LIBRARY_PATH

or in setup.py add libfreenect2_install_prefix = os.environ.get( "LIBFREENECT2_INSTALL_PREFIX", "/home/pi/Desktop/CGPraktikum/libfreenect2")

but it still same problem.
so can you give some advice?
thx in advance:)

I think it should work. Please make sure you have a libfreenect2.so or similar in your file system.

pylibfreenect2/setup.py

Lines 27 to 35 in 981d62a

	if platform.system() == "Windows":
	lib_candidates = list(filter(lambda l: l.startswith("freenect2."),
	os.listdir(join(libfreenect2_library_path))))
	else:
	lib_candidates = list(filter(lambda l: l.startswith("libfreenect2."),
	os.listdir(join(libfreenect2_library_path))))
	if len(lib_candidates) == 0:
	raise OSError("libfreenect2 library cannot be found")

thx for reply, the setup.py install is successful.
i forget my is LD_LIBRARY_PATH=/root/freenect2

may i ask should i write OpenGL ES pipeline by myself?
or what should i do can create a visual window?
because everytime i run it shows

sorry i am newbie :)

You should first check if libfreenect2 works okay on your platform.

@Jyurineko OpenGL pipeline need a monitor to run, or you can build a headless opengl library. I guessed that you run this on ssh tunnel without X forward, so you can try run this on other pipeline such as opencl or cpu or cuda. These all can work on host without monitor.

@MikoyChinese i used VNC to remote the monitor, i try direct connect a monitor to run today,
but i also tried ssh -X pi@ip address. and using VNC still same error:(

@Jyurineko :), Hah, If you want to use opengl pipeline you need a monitor or headless opengl library. But I just think that you can just use CPU pipeline or OpenCL pipeline enough.

example code:

from pylibfreenect2 import Freenect2, SyncMultiFrameListener
from pylibfreenect2 import FrameType, Registration, Frame
from pylibfreenect2 import OpenCLPacketPipeline

pipeline = OpenCLPacketPipeline()

enable_rgb = True
enable_depth = True

fn = Freenect2()
num_devices = fn.enumerateDevices()
if num_devices == 0:
    print("No device connected!")
    sys.exit(1)

serial = fn.getDeviceSerialNumber(0)
device = fn.openDevice(serial, pipeline=pipeline)

types = 0
if enable_rgb:
    types |= FrameType.Color
if enable_depth:
    types |= (FrameType.Ir | FrameType.Depth)
listener = SyncMultiFrameListener(types)

# Register listeners
device.setColorFrameListener(listener)
device.setIrAndDepthFrameListener(listener)

if enable_rgb and enable_depth:
    device.start()
else:
    device.startStreams(rgb=enable_rgb, depth=enable_depth)
