I was hoping that the stream would just be passed through and stored as is (-c:v copy -c:a copy). My use case has my dual stream camera feeding a MJPEG stream to ZM for motion detection, event review, montage review and just "Hey, who's at the front door". I've found that the rate ZM can f...

just wanted to bump this and re-ask the same question. See if there is any insight. I too am seeing a high CPU load on "record" passthrough H264 streams. Should this be the case? or should passthrough be cheap on cpu? I have to be honest, I think on a previous version of Zoneminder I had r...

Thank for that guide bbunge. An update to this saga of mine, trying to record every frame.... it's working.. again. Yeah. yeah.. I've said that before.. hopefully I won't be posting another "spoke too soon" post. I used your DB tuning wiki http://www.zoneminder.com/wiki/index.php/General_N...

An update to anybody who finds they are having a similar issue. http://www.zoneminder.com/forums/viewtopic.php?f=32&t=23529 In my efforts to fix the issues reported in that thread, my TZ issues are.. almost.. totally gone. It would appear that it's not a TZ specific issue, but in fact a performa...

Yep.. jumped the gun.. it is indeed quite a bit better... so I'm on the right track.. but I'm still losing a few frames during alarms.

So far.. it's all working. .. I say so far because I've jumped the gun a couple of times already here.. but... Ok.. so my main root partition running RAID1 is only good for <50MB/s. My main data RAID5 is good for >90MB/s. I moved my mysql DB files to the RAID5 disk. SQL test scripts I had ran 5-6x f...

Turning off the analysis images dropped the number of those "only read 219224 bytes" errors down from quite a few, to only a couple. In the end I didn't plan to leave those turned on anyway.. but it's good to know I can at least (almost) get rid of that error. I tried dropping the i-frames...

Still more experiments. I setup a tmpfs (in memory Filesystem) for both the zoneminder/tmp and zoneminder/socks and zoneminder/swap directories. No issue at all with disk IO now. Same thing.. a lot , but not all frames are recorded. Teh above zmf errors are still being recorded. It cant' be a socket...

A bit more info for this strange issue. I once again offloaded the mysql database to a dedicated temporary machine. They are hooked to decent quality gigabit switch, so there is very little, if any, DB lag. In fact, the "zm_create.sql" when run on the server machine, to the remote database...

P.S. I forgot to mention, I tried OPT_FRAME_SERVER but it didn't help at all either.

For some reason.. when alarms (or web based forced alarms) fire, I'm dropping frames. I'm running out of things to check. The kicker is, I have a 2nd test machine that I threw ZM on, and it works perfectly. So.. it's something about my main machine, but I can't yet seem to figure out what. Except fo...

I spoke too soon. It's still doing it. The one where it fixes itself after 1-2 reloads. D'Oh!

Update.. so far.. it seems to be fixed. Though, I don't know what fixed it. Previously, I'd tried re-compiling and re-installing quite a few times, but the problem remained. Though, I'd used the old-school method of ./configure to setup the build. This time, in an effort to get access to ZM Ninja an...

New tidbit of info. Having my php.ini timezone value commented out.. broke something else. the web-page interface to ZM showed the time (in the upper left corner of the page using the flat css) 6 hours ahead. It was in UTC. Resulting in the "hour" column of events being full of zero events...

My @@global.time_zone setting is also set to "SYSTEM". The fact that making these TZ changes seems to have massively improved the error tells me I'm on the right track. But.. it's still strange that it happens. At least I pretty much only need to do 1, sometimes 2 refreshes to get the stre...
