Describe the bug When I slightly change the capture_motion.py example I get an error: no such process.

To Reproduce changing only H264 to MJPEGEncoder works changing the resolution to maximum (4056,3040) I run out of memory, so added "buffer_count=2" *then error occurs

Same with *changing the resolution to 2028,1520 and buffer_count=1

Here is my code: ` import time from signal import pause

import numpy as np

from picamera2 import Picamera2 from picamera2.encoders import MJPEGEncoder from picamera2.outputs import FileOutput

lsize = (320, 240) picam2 = Picamera2() video_config = picam2.create_video_configuration(main={"size": (2028, 1520), "format": "RGB888"}, lores={"size": lsize, "format": "YUV420"} ) picam2.configure(video_config) encoder = MJPEGEncoder() picam2.encoder = encoder picam2.start()

w, h = lsize prev = None encoding = False ltime = 0

while True: cur = picam2.capture_buffer("lores") cur = cur[:w*h].reshape(h, w) if prev is not None:

Measure pixels differences between current and

    # previous frame
    mse = np.square(np.subtract(cur, prev)).mean()
    if mse > 7:
        if not encoding:
            encoder.output = FileOutput("{}.mjpeg".format(int(time.time())))
            picam2.start_encoder()
            encoding = True
            print("New Motion", mse)
        ltime = time.time()
    else:
        if encoding and time.time() - ltime > 2.0:
            picam2.stop_encoder()
            encoding = False
prev = cur`

Expected behaviour Camera should capture the motion as in the capture_motion.py example but with MJPEG Encoder and maximal resolution
