ich habe einen Raspberry Pi Zero mit einer Kamera angeschlossen, um genauer zu sein, die NoIR Kamera ist angeschlossen.
Über das internet bin ich auf ein ganz tolles Script gestossen, welches mir erlaubt via den Browser den Output der Kamera anzusehen (Live Streaming).
Nun wollte ich aber das äusserliche ein bisschen hübscher machen mit externe CSS Files und mit meinem Logo.
Hier ist mal das Script welches ich angepasst habe:
Code: Alles auswählen
import io
import picamera
import logging
import socketserver
from threading import Condition
from http import server
PAGE="""\
<!DOCTYPE HTML>
<html>
<head>
<link rel="stylesheet" href="css/styles.css">

<div class="video-container">

class StreamingOutput(object):
def __init__(self):
self.frame = None
self.buffer = io.BytesIO()
self.condition = Condition()
def write(self, buf):
if buf.startswith(b'\xff\xd8'):
# New frame, copy the existing buffer's content and notify all
# clients it's available
self.buffer.truncate()
with self.condition:
self.frame = self.buffer.getvalue()
self.condition.notify_all()
self.buffer.seek(0)
return self.buffer.write(buf)
class StreamingHandler(server.BaseHTTPRequestHandler):
def do_GET(self):
if self.path == '/':
self.send_response(301)
self.send_header('Location', '/index.php')
self.end_headers()
elif self.path == '/index.php':
content = PAGE.encode('utf-8')
self.send_response(200)
self.send_header('Content-Type', 'text/css')
self.send_header('Content-Type', 'text/html')
self.send_header('Content-Length', len(content))
self.end_headers()
self.wfile.write(content)
elif self.path == '/stream.mjpg':
self.send_response(200)
self.send_header('Age', 0)
self.send_header('Cache-Control', 'no-cache, private')
self.send_header('Pragma', 'no-cache')

self.end_headers()

allow_reuse_address = True
daemon_threads = True
with picamera.PiCamera(resolution='1280x720', framerate=24) as camera:
output = StreamingOutput()
#Uncomment the next line to change your Pi's Camera rotation (in degrees)
#camera.rotation = 90
camera.start_recording(output, format='mjpeg')
try:
address = ('', 80)
server = StreamingServer(address, StreamingHandler)
server.serve_forever()
finally:
camera.stop_recording()
Hätte da jemand eine Idee?
Danke und Grüsse
