[all info inside] Having trouble monitoring...

talntid · Post by **talntid** » Sat Feb 20, 2010 12:14 am

I am having trouble getting ZM to monitor a live feed.
You can see the live feed here: http://test:test@actinc.dyndns.org/GetData.cgi?CH=1

I am on 1.24.1

I have tried HTTP, regex, etc... lots of stuff to no avail.

I have even tried FFMPEG, and here is the command line I use to download data from it on the terminal, so you can see ffmpeg is capable of doing it...

Also if you change CH=1 to 2, 3 or 4, it will show the different cameras accordingly.

ffmpeg -y -t 50 -f mjpeg -r 15 -s 640x480 -vcodec mjpeg -i 'http://test:test@actinc.dyndns.org/GetD ... 1&Size=cif' -vcodec copy ./test.avi

I have tried changing resolution size, etc, etc... If you can get it working in your own ZM and confirm it is possible, that would be best, and I would be happy to pay for your time, if you so desire. I would just like to get this working. Any ideas?

Thanks!!

Seems the live feed doesn't use the standard format because i can't view it with my web browser (Opera 10)

even so... ffmpeg can see it, so zoneminder should also be able to I would think?

ZoneMinder is sensitive when it comes to mjpeg, and many cameras stream broken mjpeg.
ffmpeg is probably less sensitive or knows how to deal with such.

Maybe someone that knows about the format can capture your stream and analyze whats wrong and then patch ZM accordingly.

EDIT: Have you tried upgrading to 1.24.2?

I sure hope so

I would be happy to pay for their time.

I did some capturing and searching and it seems your camera streaming format is broken.

Feb 21 00:08:37 p1400 zmc_m3[28814]: ERR [Found unsupported content type 'image/jpeg;size=352x256']

Content type should be just image/jpeg, without the size part, but lets tell zoneminder to accept your camera's way.

In file zm_remote_camera_http.cpp find this line (It appears twice in ZM 1.24.2, edit in both places):

Code: Select all

					if ( !strcasecmp( content_type, "image/jpeg" ) || !strcasecmp( content_type, "image/jpg" ) )

Change to:

Code: Select all

					if ( !strcasecmp( content_type, "image/jpeg" ) || !strcasecmp( content_type, "image/jpg" ) || !strcasecmp( content_type, "image/jpeg;size=352x256" ) )

Recompile and it should hopefully work.

Thanks for your response!

What will I use for settings afterwards, just normal HTTP stream?

mastertheknife · Post by **mastertheknife** » Sat Feb 20, 2010 10:38 pm

Yeah..

Source Type: Remote

Remote Protocol: HTTP
Remote Method: Simple\Regexp (I think regex is faster, try both)
Remote Host Name: test:test@actinc.dyndns.org
Remote Port: 80
Remote Host Path: /GetData.cgi?CH=1
Color: not sure..
Capture height and width: try 352x256 (widthXheight) because thats what your camera tried to report to ZM although thats not 4:3 so im not sure, try going to the camera's setup page and copy from there.

ok, thanks.

currently working on installing from source - i had used a debian package

so to clarify, were you 100% successful in viewing the stream via zoneminder?

mastertheknife · Post by **mastertheknife** » Sat Feb 20, 2010 10:50 pm

No i haven't tested, i simply captured few packets and looked at the source to see what generated the error.

mastertheknife · Post by **mastertheknife** » Sat Feb 20, 2010 10:54 pm

I just compiled and tested and it seems there is more work to change to make ZM work with it.

Setting it to 352x256 and 24bit color got it to work, although system log is being flooded with this:
