Apache+mod_python+Python MJPEG output handler. Here I needed a MJPEG video output by a web URI. In this case I used the mod_python to handle a web request by the Apache webserver. The Python script was simply loading a list of images contained in a certain directory and that have been named in a numeric progressive way.

python_handler.py

import httplib
import cgi
from mod_python import apache
import mod_python
import string
import os.path
import sys
import time
from time import gmtime
from time import strftime

"""
Handler function for the mod_python
"""
def handler(req):
	fps = 3
	form = mod_python.util.FieldStorage(req)

	bound = "myboundary12312313"
	
	req.content_type = 'multipart/x-mixed-replace; boundary=%s' % (bound)
	req.media_type='image/jpeg'
	
	i = 0
	
	"""

	while True:
		f = open('/var/data/images/image'+str(i)+'.jpg')
		image = f.read()
		req.write("%s\r\nContent-Type: image/jpeg\r\nContent-Length: %s\r\n\r\n" % (bound,len(image)) )
		req.write(image)
		req.write("\r\n")
		f.close()
		i = (i + 1) % 3
		time.sleep( 1 / ( float( fps ) ) )
	
	return apache.OK
