MET-ECOM live snapshot

As a follow up: There currently isn’t an option to retrieve a live snapshot like there is with most cams/video servers and I submitted it as a feature request.

What I did get is a path to the stream and I figured out an acceptable workaround to extract one frame from it. Here’s how if anyone is interested:

This is the path to the stream:

http://<Met-Ecom IP>/pages/stream_cam_wg.mjpeg?source=1

Open an IP connection to the Met-Ecom and in the ONLINE: handler send a GET for the stream.

In the STRING: handler -

Look for a valid header which is terminated by a CRLF CRLF and looks like this:

HTTP/1.0 200 OK
Date: Tue Feb 17 03:10:20 1981
Server: GoAhead-Webs
Pragma: no-cache
Cache-Control: no-cache
Content-type: multipart/x-mixed-replace; boundary=--amxBoundraryV1ID

Look for the next CRLF CRLF which describes the first boundary and looks like this:

--amxBoundraryV1ID1
Content-Type: image/jpeg
Content-Length: 11007

From that you get the length of the first frame of the stream, 11007 in this case.

Let your buffer fill until it has enough bytes to complete the image.

Close the IP connection to the Met-Ecom.

In the OFFLINE: handler -

Lop off any extra data that will most likely get in the buffer before the faucet turns off.

Then you can save the .jpg to flash for future use like as an attachment in an email or text or for whatever.

It would be easier and faster to just ask for a snapshot and get everything done in the ONLINE: and OFFLINE: handlers without having to parse through the data as it comes in and then close the IP connection manually but the method described above gets the job done so life is good.
