ZoneMinder Forums

Hi,

This is my first post after hours of trawling the forums trying to find a solution.

Running 1.24.2 on Ubuntu 9.04
I have a single Panasonic IP camera which is capturing fine into Zoneminder.
Everything is wonderful and I can view the live feed from the camera from within Zoneminder fine.
My problem occurs when I am trying to view events previously captured. Upon clicking on an event, the event appears and I see the first frame of the event. If I am really lucky, I might see a few frames before the stream stops and Firefox / Safari / IE you name it becomes unresponsive (all subsequent ZM pages off the server are not displayed).
The only way to get back to normality is to shutdown the browser and fire it up again.

There must be something not right with ZMS (in my case I am running nph-zms). I have turned up the debug on this process to 9 and have captured the following (bottom half of the debug output displayed here...)

As you can see, the debug output stops whilst sending the frames (presumably to the browser) (NB this is not a copy/paste error). In this case it stopped sending after frame 24. This event has nearly 300 frames.

I know that a lot of faults in this forum are because of ffmpeg, however I am not sure that ffmpeg is actually involved in the replay of a stream.

Please help.

Oh and the following is displayed within the Apache error log after some time...

[Wed Jul 15 15:13:03 2009] [warn] [client 192.168.192.74] Timeout waiting for output from CGI script /usr/lib/cgi-bin/nph-zms, referer: http:
//ubuntu.home/index.php?view=event&eid=289&filter[terms][0][attr]=MonitorId&filter[terms][0][op]=%3D&filter[terms][0][val]=1&sort_field=Start
Time&sort_asc=0&page=1

Apache may be waiting for the script to finish outputting data before sending it to the client but it never finishes obviously so the apache error.

That would explain the apache error which doesn't appear straight away.
Any thoughts on why the script output appears to start then hangs?

did you tried using zms?

What are your options for zms?
ffmpeg is used if you are using anything other than mjpeg streaming from zms.
Are you already was jpeg for a streaming method and does it behave the same there?

My options under "Images" in the Options menu is the following;

CAN_STREAM = Auto
STREAM_METHOD = jpeg
MPEG_LIVE_FORMAT = swf
MPEG_REPLAY_FORMAT = [blank]
PATH_FFMPEG = /usr/local/bin/ffmpeg
FFMPEG_INPUT_OPTIONS = [blank]
FFMPEG_OUTPUT_OPTIONS = -r 25 -f mp4

Under the PATHS menu;
PATH_ZMS = /cgi-bin/nph-zms

I have tried changing this to /cgi/zms but the same symptoms occur.
