Hi Ashwani,

The systems are two Polycom VSX video conference devices.

They work perfectly with an earlier build of OpenMCU on a FreeBSD server, and the screen splits correctly, but the quality is 176x288 (from memory) for the view of all four cameras, so individual camera resolutions are approximately 44x72px. Not really able to see anything at all in them.

I know the cameras all work with that version of OpenMCU, but are not switching in this one.

Hi Victor,

can you confirm video capture device (camera) is connected to your system?

Regards,
Ashwani

Just on this…

I have attached logs of this issue, and have noticed a lot of lines with, “VideoGrabber is unavailable”. Is this something to do with the issue described below?

Thanks in advance!

Hi Simon,

I can’t see any difference in the logs with environment variable PTLIB_TRACE_CODECS set to 4. Should this just be going to the regular OpenMCU log (/c:\trace.txt)?

Also, even if I am temporarily stuck with H.261, when new endpoints join, video on the first endpoint freezes, and the new endpoint is not displayed until either endpoint disconnects, then it switches back to whichever endpoint is still connected and video resumes.

Any ideas on that?

Victor

The reason why your codecs are loading and then unloading is that the codec checks to see if all the dependencies are present and if they are not then the codec is unloaded.

It is not clear on the platform you are running on but make sure you have both x264 and FFMPEG dependencies binaries are in path.

Using environmental variable PTLIB_TRACE_CODECS = 4 to output trace log information on why the dependencies are not found.

Hi guys,

I’m getting stuck with OpenMCU loading, and only starting the H.261 codecs.

It seems it can detect H.263/H.264, but removes them shortly after detection, and then only shows one set of codecs in the video section of the startup.

Logs:

I’m also seeing no split screen video – When new endpoints join, video on the first endpoint freezes, and the new endpoint is not displayed until either endpoint disconnects, then it switches back to whichever endpoint is still connected and video resumes.

Can anyone help?

Thanks!

Victor
