Hi, I'm trying to use NDI to process some image from another software with CV2, so, at the moment, I just trasformed the received fram in numpy array and display it.
After a few seconds I get this message: Process finished with exit code -1073741819 (0xC0000005).
I'm using Python 3.9.18 on Windows 10 in a I7 7th generation
This is the code:
import sys
import numpy as np
import NDIlib as ndi
import cv2
def main():
if not ndi.initialize():
return 0
ndi_find = ndi.find_create_v2()
if ndi_find is None:
return 0
sources = []
while not len(sources) > 1:
print('Looking for sources ...')
ndi.find_wait_for_sources(ndi_find, 1000)
sources = ndi.find_get_current_sources(ndi_find)
for i, s in enumerate(sources):
print('%s. %s' % (i + 1, s.ndi_name))
ndi_recv_create = ndi.RecvCreateV3()
ndi_recv_create.color_format = ndi.RECV_COLOR_FORMAT_BGRX_BGRA
ndi_recv = ndi.recv_create_v3(ndi_recv_create)
if ndi_recv is None:
return 0
ndi.recv_connect(ndi_recv, sources[1])
ndi.find_destroy(ndi_find)
while True:
t, v, a, _ = ndi.recv_capture_v2(ndi_recv, 5000)
if t == ndi.FRAME_TYPE_NONE:
print('No data received.')
continue
if t == ndi.FRAME_TYPE_VIDEO:
print('Video data received (%dx%d).' % (v.xres, v.yres))
ndi.recv_free_video_v2(ndi_recv, v)
image = np.copy(v.data)
cv2.imshow('NDI', image)
continue
if t == ndi.FRAME_TYPE_AUDIO:
print('Audio data received (%d samples).' % a.no_samples)
ndi.recv_free_audio_v2(ndi_recv, a)
continue
ndi.recv_destroy(ndi_recv)
ndi.destroy()
return 0
