round robin - possible or not?

I have several network cameras, but I'd like to stream video from them using only one "capture window" / one MJPEG image - thus, one stream should just change the cameras after another, or round-robin (every few seconds).

There was a similar topic about "round robin" subject:

but still I'm not sure it's very related, it didn't bring clear answers to my question.

All right, I guess that's what "Cycle" provides

However - "Cycle" only streams in MJPEG, not in MPEG - is it possible to change it?

I want to stream video from several cameras in this round-robin fashion on a website; using MJPEG takes just too much bandwidth.

I could transcode MPEG on-the-fly with VLC to use less bandwidth.
It's also possible to transcode MJPEG on-the-fly with VLC - but when we use "Cycle", MJPEG picture link changes when the cameras are cycled.

Solutions?

You will find those setting in options and is covered in the manual.

Really? I can indeed set MPEG streaming, but it only works for:

1) viewing separate cameras (i.e, when we click on a camera name)
2) viewing "montage" - all cameras on one page

For "cycle", MPEG streaming just doesn't work - always MJPEG is used.

If there indeed is an option to stream "cycle" as MPEG, please tell me where it is - I couldn't find it in the manual.

I forgot that feature was broken in the source

I have the patch some where, just a question of where

Should be posted the file to patch would be html_view_cycle.php

[edit] I searched the forum and it's MIA, I know we had some database problems around the same time and it must have affected that post along with a lot of other missing posts from that period. I still have around 80 Gigs of data to dig through so I'll try to find it and repost it. Can't say exactly when though.

OK, thanks anyway.

Will ping this thread in a couple of days to remind you (if you still can't find it).

80 gigs, you be lucky to see it in a month. Not all the drives have even been loaded on the new machine yet. A search didn't turn up anything either but that don't mean I remember what I named it
