慢速通过UDP发送摄像机图像

I am trying to stream images from a Camera on my Raspberry Pi via UDP. I'm receiving / displaying them on an Android device.

我试图通过UDP从我的Raspberry Pi上的相机流式传输图像。我正在Android设备上接收/显示它们。

According to my calculations, my application sends at a maximum rate of 10fps, but I need 25 fps.

根据我的计算,我的应用程序以最大速率10fps发送,但我需要25 fps。

Does anyone know how to speed my solution up, or have a better solution?

有谁知道如何加速我的解决方案,或有更好的解决方案?

My code is as follows

我的代码如下

sock=socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
sock.connect((UDP_IP, UDP_PORT))
camera = PiCamera()
camera.resolution = (640, 480)
camera.framerate = 30
rawCapture = PiRGBArray(camera, size=(640, 480))
time.sleep(0.1)

for frame in camera.capture_continuous(rawCapture, format="bgr", use_video_port=True):
    image = frame.array
    img = Image.fromarray(image,'RGB')
    output = StringIO.StringIO()
    img.save(output, format='JPEG')
    contents = output.getvalue()
    output.close()

    sock.send(contents)
    key = cv2.waitKey(1) & 0xFF
    rawCapture.truncate(0)
sock.close

No need to reinvent the wheel here. Are you trying to make an IP camera? Implement ONVIF streaming. See "5.1.4 JPEG over RTP" for JPEG over UDP format

无需在这里重新发明*。你想制作一台IP摄像机吗?实施ONVIF流媒体。有关JPEG over UDP格式,请参阅“5.1.4 JPEG over RTP”
