Question

I have a program that can generate video in real time. Now I would like to stream this video online while it is being generated. Does anybody know an easy way to do it?

I am describing a CGI approach I tried but did not work, but please note that I am open to all options that would achieve my goal. I am just wondering if anybody knows why my approach doesn’t work and how I should fix it

I set the content-type to mpeg for example, and print out a chunk of data in the mpeg file periodically. But the video only lasts for very short amount of time and stop streaming. My code is something like this (in Python).

print "Content-type: video/mpeg"
print
f = open("test2.mpg")
while (True):
    st = f.read(1024*1024)
    sys.stdout.write(st)
    time.sleep(0.5)

Though this would work fine. I really don’t see why the output of these two programs are different. But obviously I can’t use this approach since i can’t wait until the entire file is generated before reading in.

print "Content-type: video/mpeg"
print
f = open("test2.mpg")
print f.read()

Answer 1

What type of file is test2.mpg?

If it’s an mpeg4 file your approach won’t work because you will have headers at the start or end of the file.
If your file is an mpeg2 transport stream, then this should work.
