Unsupported media SDP .. 'application 0 RTP/AVP 107'

Hi *,

actually I'm referring to the following post "PLANET ICA-HM316" - from Wed Nov 23 back in 2011. The firmware used on ICA-HM316 is identical to such used on models ICA-HM132 and HM136 (indoor types).

So, while having the camera configured to stream MJPEG instead of H.264 - ZoneMinder throws the following error:

Code: Select all

zmc_m13[4240]: ERR [Unsupported media type 'application' in SDP media attribute 'application 0 RTP/AVP 107']
From my understanding the expected profile for MJPEG should to be RTP/AVP 26 (JPEG Video) and not RTP/AVP 107.

Is this a misbehavior of the firmware/camera or does support has just to be added to ZoneMinder?

I also didn't manage to find the respective profile - 107 - referenced on the .. Is this some sort of combination between used audio+video profile?

As seen on the screenshot above the audio codec is G.711.

BTW: I can't use H.264/RTSP for motion detection due to known issues with image distortion and artifacts when running ffmpeg/avconv in low-light scenarios.

I've documented the H.264/RTSP setup I've got running in the wiki.

That portion of zoneminder is not something that I am familiar with so I don't have an answer to your exact question.

However, I do have good news. The next version of zoneminder will support a new method called "libvlc". As the name implies, if you install the libvlc libraries onto your system, zoneminder should support any camera that currently works with vlc. Your camera would be an excellent candidate to test this new method.

You can either wait until the next version of zoneminder is released, or build zoneminder off the current master branch on github right now.

I've patched the source in order to support the content type described (see ... ype#p77658). I'm running 1.26.4 and noticed initial libvlc support but haven't tried it yet. But to me it seems like native MJPEG support works best in the first place. Thanks for the suggestion!

FYI: Using libvlc support with the latest ZM version being 1.29.0 everything runs smooth :)
