Edit: After hours of research, i found out, that its an old bug (for several years now!) from ffmpeg. So we arn´t able to use h264 streams ... But read the rest, then you will see.

Its maybe the same problem with other postings, but i wish to specify my problems, don´t know if they difference...

Setup:
- ubuntu 12.04.03 with zm and avconv, both from ubuntu running in a kvm-vm with 4 cores on a quadcore xeon server System, 2gb ram for vm
- upgrade with iconnor ppa, needed to correct the database path in zm.conf for getting it sucksessful.
- 4 MP Cams (3* Level One wcs-0030 1280*800 with h264 or mpeg , 1 * older axis with only 1280*1024 mpeg)
- watching the zm on a second monitor with firefox, on ie i never get a picture (cambozola plugin is not fine, it fills my harddrive till it´s full)

when i configure all cams with mpeg i get a poor frame rate of 15 Frames. only with h256 i will get till 30 frames (in zm shown 25) My system load is nearly full with maximum framrate and when motion is in the picture (no motion detection enabled) it gets first slower and after a few seconds it runs with ultra fast speed... not really working good.

So i tought i should better use h264. But its amazing to get it work. No dokumentation is here, because all the option for ffmpeg are a secret (for me). Together with other secrets i don´t understand.

My unknown things are all from options Menu:
- why i have no picture when switching from jpeg to mpeg, te browser changes to vlc but no video
- video stream format under picture, what shall we use here??? swf or asf ? Or anything else is better?
- ffmpeg options seems to make no difference! same picture alle the time, no quality changes. i used this settings: http://www.zoneminder.com/wiki/index.php/Ffmpeg
- ffmpeg output format ??? no changing anyway i use h264, mpg, avi, etc

I thing with the correct ffmpeg options it would work fine with h264 streams, correct?

I would be happy for every help, i last so many hours with getting better results.

Thanks

Are these files actually there? /tmp/zm/zms-334825s.sock

What are the permissions/ownership like. Can your user that runs Apache access them?

at this moment i have a live video with mpeg, after i deleted MPEG_LIVE_FORMAT .
the tmp owner is www_data, but the picture quality is still very poor.

apache user should be the same, how can i proove it ? can you join irc?

Edit: ah i know what gets me a picture under ff, i disabled auto detection of browser capability to force using cambozola. And it does it, but the picte problem is still the same like using firefox nativ

Posted: **Fri Sep 20, 2013 6:22 pm**

If you want to check web user you can run ps -ef | grep apache . You'll see the zm processes there too.

I presume you are running 1.26.3. 1.26.x certainly better performance, lower load.

Do you _need_ such a high framerate?

Posted: **Fri Sep 20, 2013 6:28 pm**

yes it 1.26.3.

so thats ok.

10 Fps isnt really much, controlling the frame rate is also very irritating. i set the cams to 10fps, so the web monitor shows this fps also. but inside the options i seemd to be unable to controll it anywhere. I would like to have more fps on 1280*800, because my cams are capable of 25 fps on good light conditions. But this is only for live view. when i record it i thing 10fps are enough. If the system power is enough...
i haven´t recorded anything till now, because i couldn´t get it run without this disturbing picture.

Posted: **Fri Sep 20, 2013 6:33 pm**

i have upgraded ffmpeg with ***//launchpad.***/~jon-severinsson/+archive/ffmpeg?field.series_filter=precise that should be the new enough.

But i also don´t understand the controlling of picture tab. so many option, with no explanation wich helps. what should i enter here for a working h264 stream over ffmpeg?

and i also can´t see in htop that ffmpeg is beeing used. Why not?

Posted: **Fri Sep 20, 2013 6:34 pm**

Is that with ZM stopped? I'd expect to see the ZM processes show up too.

Posted: **Fri Sep 20, 2013 6:41 pm**

yes this is with a running zm. But it also the same when i stop zm.

how can i see wich command is used for ffmpeg? is that with ps also possible ? i can see ist activ, but not more. Its maybe interesting if it uses my parameter from webif.

Posted: **Fri Sep 20, 2013 6:53 pm**

how crazy is that? i changed path_ffmpeg from /usr/bin/ffmpeg to /usr/bin/ffmpeggg restartet zm, but i still have a video???? i believe my path_ffmpeg isn´t used, therefor i can give ffmpeg options like i want, nothing will change ...

next i noticed is, that if i leave mpeg_live_format empty i get the video with mpeg but i don´t know what is used for showing it.
If i set any option in it like asf or mkv vlc will start in the live web window but showing only a black screen and with this error for 4 cam activ:

i have found the reason. Short form: ffmpeg has problems with udp stream over rtsp.
https://trac.ffmpeg.***/ticket/285

I found no way to force ffmpeg to connect over tcp, wich would be a soulution.

Maybe someone has an idea, but the problem is old and therefor i will better forget to try it anymore. Spend the hole evening for research.

>i have found the reason. Short form: ffmpeg has problems with udp stream over rtsp.
problem with fragmented packets... patch from warmcat (url see in messages, as new user i can`t post it) solved this problem...

but it`s so old...

I offer my patch (on current version - 1.26.3) see attached file
