I am trying to parse a mjpeg stream out of an html response. The http server is using server push to push the stream of jpegs to the client. I have written a test client and am able to receive the stream but am having trouble figuring out what Perl libraries I need to use to separate and save the individual jpegs as actual jpegs and not MIME encoded data.
The Content Type is "multipart/x-mixed-replace; boundary=--myboundary". "--myboundry" is the flag used to delimit the individual data fields.
This is a stream of JPEGs so, the server will continue streaming as long as the connection is open. I am using the Net::HTTP library since I have to parse as it arrives rather than wait for the whole page to be downloaded (since it can't be).
The stream's format: #--------------------------------------------------------------------------------- HTTP/1.0 200 OK Connection: Close Server: Camd Content-Type: multipart/x-mixed-replace; boundary=--myboundary
--myboundary Content-Type: image/jpeg
<SOME JPEG IMAGE>
--myboundary Content-Type: image/jpeg
<SOME JPEG IMAGE>
--myboundary Content-Type: image/jpeg
<SOME JPEG IMAGE>
--myboundary . . . #---------------------------------------------------------------------------------
I am able to break all of the pieces out of the original stream and am currently just saving them to a file:
chunk-1.mime
#---------------------------------------------------------------------------------
Content-Type: image/jpeg
<SOME JPEG IMAGE>
#---------------------------------------------------------------------------------
Can anyone point me in the direction of the libraries or tools I need to use to export the encoded <SOME JPEG IMAGE> to a raw JPEG so I can save it to a file?
Can't you just strip out "Content-Type: image/jpeg\n\n"?
