Sony SNC-M3W support ready for testing.

gneuf · Post by **gneuf** » Sun Mar 19, 2006 5:15 am

I've added some code to zm_remote_camera.cpp and zm_remote_camera.h so that it can understand the mjpeg streams transmitted by the Sony SMC-M3/M3W (and presumably the SNC-M1/M1W).

Since I accidentally reformatted the code in my haste to get it working, making a diff produces a ridiculous patch file...

So, I've posted it here as a gzipped tar file containing both sources.

For now, backup the two files named above from your ZM ".../src/ " directory to somewhere safe (!), and replace them with the two files in this archive.

Then, in the ZM top-level directory, at a shell prompt, issue the command:

shell> make && make install

This should recompile and reinstall ZM with the modified zm_remote_camera routines.

IMPORTANT NOTE

For now, you must set the camera to the following configuration using (gulp) Internet Explorer:

MJPEG Mode
320x240 Image size
Frame rate 5 (or another value of your choice - just remember it for creating the monitor - the values must match for now)
Microphone disabled

Then, you can create a new monitor with the following values:

General
Name: <Your Choice>
Source: Remote
Function: Monitor
Maximum FPS: 5 (or the value you set with Internet Explorer)

Source
Remote Host Name: username:password@<camera ip address>
Remote Host Port: <camera remote port> (usually 9000 unless you changed)
Remote Host Path: /mjpeg?speed=5 (or the speed value you set with Internet Explorer)
Remote Image Colours: 24 bit colour
Capture Width: 320
Capture Height: 240

Once that's set, you should see video when you watch the new monitor!

Todo:
Make it modular so as to support other non-http/non-standard MJPEG headers from other cameras by simply describing the format of the header.
Re format it so a DIFF can be taken.

Warrantee: None of the available Warrantees.

Thanks for this. If you can mail me a diff when you get one I will put it 1.22.1 in the next couple of days.

Looks like I'll have to re-edit from the original source to get a *changes-only* diff. Possibly I'll even get to it tonight: last night I got the SNC-M3W control script to work! Cleaning it up tonight, which should only take an hour...

This is awsome!! The problem is the link is broken

is there another way to get this?

First off, thanks to gneuf for fixing the link, you rock! I got the files and rebuilt ZM but when I create the monitor I only get a black window. What is the ETA for the 1.22.1 with support for this camera? Thanks

I'm processing the diff now for 1.22.1 for upload. I reformatted the original code and it makes a *huge* diff. I'm hand re-editing the code to reduce the diff to only the altered code.

You *must* be sure to set the camera to *no* sound (microphone *off*), as I haven't been able to test my hack that discards the sound packetry if the microphone is left on...sorry. And you must set the camera to a resolution that matches the rez you enter in the camera setup in ZM, e.g. camera rez in Internet Explorer setup window = u pixels by v pixels, camera rez in ZM = u pixels by v pixels.

Meaning: if you make the camera rez=320x240 in the Sony ActiveX setup window using Internet Explorer (the only way to set the camera parameters!), then you must setup the ZM camera specs to the *same* rez = 320x240.

Otherwise, the ZM code (wisely) will display only a black window.

Should that fail, turn debugging on to the max (meaning: set it to the value "9"), and send me the ZM debug output and I'll fix it as fast as I can.

I hate it when it works for me and fails for others!

So is this code in 1.22.1? I have a SNC-M1 and I get the black screen too...

EDIT: See PM for debug logs location.

The offending line is:

05/08/06 15:30:59.244514 zmc_m1[19516].ERR-zm_image.cpp/440 [Attempting to crop outside image, 0,0 -> 320,240 not in 320,240]

Seems odd, even though i have the size set properly from what I can tell.

This is due to a ZM problem with resizing monitors. It is fixed in 1.22.2 but for now you should re-edit your zone and make sure that the points only range from 0->319 and 0-239.

Apparently gneuf's code hasn't made it into the 1.22.1 release.

gneuf: can you provide us with a diff against the official 1.22.1 files?

I've got three SNC-M1 cameras and I'd really like to get the streams directly from them if possible...

Cheers,
Ulrich

Yes, since I never got the 1.22.0 diff finished and turned in [blush].

Of course, I'll have to install 1.22.1 and then carefully edit-in the changes without messing up all the whitespace, as I did before.

I'll try to do that this evening. Sorry it's taken so long: Life is what happens to you while you're making other plans.

Did you get a chance to make the changes?

Cheers,
Ulrich

gneuf · Post by **gneuf** » Fri May 26, 2006 6:53 pm

Yes...but something's not working. I'm getting black after a few seconds of video. This happened when I modified the code the first time - it had to do with discarding the sound data from the camera. Can't remember what I changed to solve it, but I'm sure it'll come back to me when I take a third run at it.

You know how it is - code never works on the first try, and if it does...no one was watching!

I'll probably get it sorted out by this evening - I can get back to testing it after work today...sorry it's still taking some time. I'll do my best to get it done before morning.

Ok, got it!

The two required patches plus the rudimentary control script for the camera (work-in-progress) are zipped into zm_remote_camera-patches.tgz.

I'd like to take some time and take advantage of the new "format" enum. The added logic renders this little hack into a *big* hack.

I need to properly code this hack into the new zm_remote... logic.

For now, for those in a hurry, this works.

Warning: If you're not running libpcre, then this patch doesn't work (yet). Easy fix - I just didn't put it in yet.

Hey! Works like a charm.

Thanks for taking the time to update the patch.

This would be a useful addition to the Wiki entry for that camera, if you feel like edting (or creating) an entry
