Buffer__get__buffer truncated 64-bit address information cause _get_raw_buffer Windows fatal exception: access violation #458

Open JYLEE2017 opened 1 month ago

JYLEE2017 commented 1 month ago

Describe the Issue When I try to access raw_buffer in Buffer, an access violation error will be reported.

To Reproduce Steps to reproduce the behavior:

  1. Go to '...'
  2. Click on '....'
  3. Scroll down to '....'
  4. See error

Sample Code I can show a piece of code that demonstrates the reported phenomenon:

If yes, please provide a sample code:

def acquire(device, features):
    global TRIGGER_SOFTWARE, POINTCLOUD_DATA_INDEX, MONO_DATA_INDEX, CONVERSION_FACTOR
    buffer = device.fetch_buffer(timeout=10)

    # Grab component data
    components = buffer.payload.components
    print("Got the following components")
    print(components)
    print("End of components")
    pointcloud_data = components[POINTCLOUD_DATA_INDEX].data
    mono_texture_data = components[MONO_DATA_INDEX].data

CTI_FILE = "F:\\software\\GenICam3D\\ProducerGEV\\x64\\Release\\ProducerGEV.dll"
SERIAL_NUMBER = "xxxx-L (xxxx)"
TRIGGER_SOFTWARE = "TriggerFrame"

POINTCLOUD_DATA_INDEX = 0
MONO_DATA_INDEX = 1
CONVERSION_FACTOR = 0.001

def main(args=None):
    from harvesters.core import Harvester
    harvester = Harvester()
    harvester.add_file(CTI_FILE,check_existence=True,check_validity=True)
    harvester.update()
    device = harvester.create()
        #{'serial_number': SERIAL_NUMBER})

    features = device.remote_device.node_map
    #SetSettings(features)

    device.start()
    print("Starting acqusition")
    #while (True):
    for i in range(1):
        print("--------------------",i,"-----------------------------")
        acquire(device,features)

    device.stop()

if __name__ == '__main__':
    main()

If applicable, please paste the actual output (its whole traceback, etc) here:

>>>buffer = device.fetch_buffer(timeout=10)
  Base Addr: 18e9c44c060
Windows fatal exception: access violation

gentl.Buffergetbase return 32bit address,Truncated 64-bit address information；This caused the above problem, but I don’t know why the _get_base interface is truncated.
