|
w.VideoHandlerThread().display()
|
|
|
|
#### Change Display Arguments
|
|
import cvpubsubs.webcam_pub as w
|
|
|
|
video_thread = w.VideoHandlerThread(video_source=0,
|
|
callbacks = w.display_callbacks,
|
|
request_size=(800, 600),
|
|
high_speed = False,
|
|
fps_limit = 8
|
|
)
|

|
|
video_thread.display()

|
|
#### Run your own functions on the frames

def redden_frame_print_spam(frame, cam_id):
|
|
frame[:, :, 0] = 0
|
|
frame[:, :, 1] = 0
|
|
print("Spam!")
|
|
|
|
w.VideoHandlerThread(callbacks=[redden_frame_print_spam] + w.display_callbacks).display()
|
|
|
|
#### Display multiple windows from one source
|
|
import cvpubsubs.webcam_pub as w
|
|
from cvpubsubs.window_sub import SubscriberWindows
|
|
|
|
def cam_handler(frame, cam_id):
|
|
SubscriberWindows.set_global_frame_dict(cam_id, frame, frame)
|
|
|
|
t = w.VideoHandlerThread(0, [cam_handler],

|
request_size=(1280, 720),
|
|
high_speed=True,
|
|
fps_limit=240
|
|
)
|
|
|
|
t.start()
|
|
|
|
SubscriberWindows(window_names=['cammy', 'cammy2'],
|
|
video_sources=[str(0)]
|
|
).loop()
|
|
|
|
t.join()
|
|
|
|
#### Display multiple windows from multiple sources
|
|
iport cvpubsubs.webcam_pub as w
|
|
from cvpubsubs.window_sub import SubscriberWindows
|
|
|
|
t1 = w.VideoHandlerThread(0)
|
|
t2 = w.VideoHandlerThread(1)
|
|
|
|
t1.start()
|
|
t2.start()
|
|
|
|
SubscriberWindows(window_names=['cammy', 'cammy2'],
|
