Saving image in the loop freezes #133
Description
I am capturing image from webcam using code from demo. Unfortunately after triggering capture with camera button in ImageRecorder, I see only 3 updates in the output Image and then the loop freezes.
camera = CameraStream(constraints={'facing_mode': 'user', 'audio': False, 'video': { 'width': 640, 'height': 480}})
image_recorder = ImageRecorder(stream=camera)
out = Image()
stop_process = False
def process_image(_):
if stop_process:
return
out.value = image_recorder.image.value
image_recorder.recording = True
image_recorder.image.observe(process_image, names=['value'])
image_recorder.recording = True
HBox([out, image_recorder])
I found that this can be functionally solved by setting callback to image_recorder.recording change by image_recorder.observe(process_image, names=['recording']), but this is only workaround of the bug.
