I want to know if it is possible to upgrade from 1.22.1 to 1.22.2 without any compilation. On looking at the changelog it appears that most of the changes are in the management scripts rather than in the underlying binaries. Will it be possible to upgrade just by replacing the pl, pm and php files ...

When I try to convert an image recorded at 4 frames per second in jpeg into mpeg at 25 frames per second (which a lot of Windows mpeg players require), the result is smeared images. I intend to get round the problem through extrapolating the jpeg frames by repeating each jpeg image 4 or 5 times to ...

When previewing the PurgeWhenFull filter in the GUI does the Limit to first XX results only; option determine the number of events deleted at a go? It should just purge the oldest events to bring the total down to the limit. Could be your PurgeWhenFull filter is a bit broken, or another filter is ...

ZM appears to have a purged almost all the events. I set ZM to use the PurgeWhenFull filter.

Does that filter purge all the events or does it purge enough of the remaining files to keep the space within that limit?

How does zmaudit handle deleted files - I mean the jpeg files themselves, not the folders relating to the events?

jameswilson wrote:that would need a mod to zm audit. You could put the link the mpeg in the notes of the event i suppose

My idea is to create a small highly optimised jpeg for each image, or even fewer images which display a message indicating where the mpeg can be downloaded from. In fact it could be nice if zm could transparently handle the case where all the jpeg files could be replaced by links to the same image ...

Bump?

I am trying to reduce the file space used by ZoneMinder to allow more days to be saved. The steps I want to use are: 1. Create the mpeg 2. Delete all the jpegs 3. Change Links to jpeg playback to point to mpeg file Is there a way of doing this without zmaudit.pl deleting the event records from the ...

When I use ffmpeg to encode a low frames per second view, it comes out blurred. Eg I capture at mostly 4fps. Is there a way of ffmpeg to generate an image that plays like the low frame rate it was recorded at, perhaps by interlacing the frames by repeating each frame by repeating the frames say 25/4 ...

The machine is an AMD 3200 with 1Gb of ram, and the values for shared memory are as below. It has 5 cameras doing 4 frames per second, two at 352x288, and 3 at 320x240, and they are all doing plain recording. cat /proc/sys/kernel/shmall - 201326592 cat /proc/sys/kernel/shmmax - 201326592 Below are ...

Whenever I do a submit on my PurgeWhenFull filter, the same records keep showing up, and it makes me wonder if there isn't something wrong there.

My ZM_FILTER_EXECUTE_INTERVAL is set to 60 secs and I think that everytime I run it new records should show up.

What could be wrong?

if you rename a file without telling zm you have then zm will not be able to retrieve images. If you need this then i suggest you rename a copy of the data and move it elsewhere as i cannot see how you could tell zm that event 5334656 is realy cammxxxOn12/12/2006 etc etc I am referring to the Name ...

I want to run a script to change Event names at regular intervals. To something such as CameraX_YYYYMMDD_HHMM-HHMM. Will doing so directly have an effect on the behaviour of the other scripts, such as video generation etc?

I want to reclaim space by purging events in the database which are a certain number of days old.

If I delete them directly from the events database, will ZoneMinder check the frames database and the file system and get rid of the records and directories later?

I keep seeing this message in my logs?
