Linksys WVC-200 PTZ finaly working

I think that this is good news for all users of this cheap PTZ, the camera finally streams live with firmware v1.2.1. and Zoneminder 1.24.1.

Now the settings:
ZM
Source Type: ffmpeg
Maximum FPS and Alarm Maximum FPS: 10
Source Path: http://camera_address/img/video.asf
Width: 640
Height: 640

Camera:
Image type: MPEG-4
Resolution: 640x480
Fixed quality: Normal
Max Frame Rate: 10

I am having some issues though with the live picture either pixelating at camera's Fixed quality settings at regular intervals (every 5 seconds) or the whole ZM freezing in high quality settings after 30 seconds. By ZM freezing I mean a complete lock-up, the web interface just stops responding and I have to restart the daemons. Nothing strange gets logged either.

It seems to be more pronounced when there is a lot of movement in front of the camera. I have compiled the latest stable ffmpeg so there is not much more that I can do there. I tried to vary the ZM Image buffer size but had no luck with it.

Also there is a real time lag of approximately 5 seconds.

I wonder how should I approach this freezing issue, any hints?

Thanks,

Peter

You don't say whether this is using Firefox on the same machine or does it matter?
The 5 second lag is likely the player buffering the stream, they all seem to do that with asf.

Thanks again for a great post. 8)

Hi Cordel,

I have two WVC-210 hooked into the ZM running on Fedora Core 8 and they preview fine, it is only this WVC-200 which is there as a third camera that is misbehaving. I am viewing it in Firefox 3.08 on a separate networked machine.

On a different note:
The WVC 210 stream mjpeg, in theory the WVC200 should do the same, the WVC200 stream /img/video.mjpeg renders fine in firefox but zoneminder displays only a black window albeit with the ZM timestamp advancing so I had to use the asf instead.

Cheers.

Any errors of interest if you raise the debug and limit it to zmc?
