EyeZM errors on zm 1.27

[sipi]

Hi,

I have two strange errors on EyeZM with zm 1.27.

Firstly, after when I updated my zm to 1.27 then the EyeZM can't work with zm 1.27. I tried what stealthy recommend to make some changes in /usr/share/zoneminder/skins/xml/skin.php file (http://www.zoneminder.com/forums/viewto ... 31&t=22035) but it wouldn't work me properly. When I start the EyeZM app on my iPhone then the EyeZM can't connect to zm 1.27 and I have an popup error message on my phone:

Error Connecting
Server cannot locate sub-view of XML Plugin. XML Plugin installation may be corrupted.

Then I heve an error message in the EyeZM's log on my phone:

EyeZM: XML Parser Error: XML Parser Error 4, Page is Empty. Check that XML plugin is installaed correctly.
EyeZM: Could not parse server ZM, error reason: server cannot locate sub-view of XML Plugin. XML Plugin installation may be corrupted.

If then I stop run of the EyeZM app (I don't close it because EyeZM stays in the background memory) and restart it then it can connect to my zm 1.27. Then I can view Monitor streams. If I close the app (it doesn't stay in the memory) then I start it again I have same problem and it is repeated every time.

Secondly, if the EyeZM can work with zm 1.27 than I can view IP cams streams but I can't view streams from my analog ProVideo card. The Eyezm loads and loads but there isn't any picture. There is any error message and I found in the EyeZM's on my phone:

EyeZM: Starting 704x576 feed for Monitor ID 1.
EyeZM: Validated monitor 1 to use Codec for streaming.

Has someone any idea?
Thanks.

Hi,

I worked on this problem under last week and I find some strange things.

The problem is zm 1.27 has an error when I try to use analog cams on ProVideo card or on Axis A240Q IP video server with 4CIF (704x576) resolution and 8bit grayscale (Target color space). This problem was after I used stealthy's recommend changing (http://www.zoneminder.com/forums/viewto ... 31&t=22035).

Can someone change it in the zm source code?

If I manually setup an 4CIF cam (I can't use Preset or save it, please read this: http://www.zoneminder.com/forums/viewto ... 31&t=22194) I find this in the EyeZM log on my iPhone:

EyeZM: Starting 704x576 feed for Monitor ID 1.
EyeZM: Validated monitor 1 to use Codec for streaming.

and in the zm's log:

and in the "weblog":

These errors show that zm can't stream the 4CIF pictures in 8bit grayscale to EyeZM because it has an undersized buffer error. I don't understand because this problem was made in the zm 1.25 and 1.26.x. I found the zm_image.cpp and zm_signal.cpp was modified and I think these are the cause of problem. Yes, I know that source was modified for less CPU usage and properly working but I don't know how can someone fix these problem because I think maybe it can fix in the source code and not need to change EyeZM. It is important because EyeZM developers haven't answered any forum problem or direct e-mail for two years.

But there is an very strange situation. If I change Monitor color from 8bit greyscale to 24bit color then EyeZm can load picture stream but have an error message in the log:

2014-04-24 15:28:18.157135 zms 10660 ERR Attempt to directly assign buffer from an undersized buffer of size: 245532 /home/abuild/rpmbuild/BUILD/ZoneMinder-1.27.0/src/zm_image.cpp 344

The problem is that my analog cams serve black and white image... if I change it 24bit color they use more cpu and rive space...
Other problem is that isn't a correct situation because when zm streams pictures to EyeZM then zm will write continously these error to log under the connection.

Did somebody experience this on his iPhone? Can somebody help to EyeZM users?

Thanks a lot.

EyeZM login works properly now because monex made a patch for suse. Thanks for monex. I think it will be good if someone improves this in the source code.

But EyeZM can't shows stream properly from the cam what I use 4CIF resolution and 8bit greyscale. It is very strange because EyeZM can shows Montage stream from this cam without any error message but when I try to view direct stream from this cam I get an error message and it can't shows the stream:

2014-05-03 00:14:44.892079 zms 11305 ERR Attempt to directly assign buffer from an undersized buffer of size: 81844 /home/abuild/rpmbuild/BUILD/ZoneMinder-1.27.0/src/zm_image.cpp 344

I don't understand how can EyeZM show the stream in Montage view and it can't show only this cam stream. Any idea?

I have this problem too. I will edit this post shortly with my progress. I am very unhappy that there is no other ZM client for apple; The android client I use works perfectly, and it's free!

Hi,

I can eliminate my problem between ZM 1.27 and EyeZM. The problem is that ZM 1.27 can't send stream to the EyeZM when I'ld like to see a camera Live Feed if the camera's resolution is 704x576 and color is grey scale (8 bit). When I see a Montage view on the EyeZM I can see this camera's picture but it is smaller than Live Feed picture size. When I'ld like camera's Live Feed I have an error message. The error message is

zms 11305 ERR Attempt to directly assign buffer from an undersized buffer of size: 81844 /home/abuild/rpmbuild/BUILD/ZoneMinder-1.27.0/src/zm_image.cpp 344.

This means that there is a buffer size problem. I suspect that buffer memory management has changed in the ZM 1.27 and and this is the cause of the problem.

Because I'm interested in who uses EyeZM on the iPhone with ZoneMinder 1.27? Has someone got analog camera with 704x576 px resolution? How someone use it, it connected a video card (ex. Provideo PV-149) or a video server (ex. Axis A240Q) which connected to ZM 1.27?

Which OS is used (CentOS, Debian, SuSE, etc)? Which platform is used (i585, x86_64)?

Does everything work fine? Can ZM 1.27 stream mjpeg and h264 encoded stream to the iPhone?

Thanks for all the information.

Hi,

If have with Eyezm and Zoneminder 1.27 in live view allways the message "Attempt to directly assign buffer from an undersized buffer of size: xxxxxxx" in the log.
Is there someone who knows how to solve this problem because i get no answer from the developer of Eyezm.
Or do you know another Zoneminder App for Iphone or Ipad ?

Regards

Eyezm users are in a tough spot right now. I've seen multiple reports the author isn't maintaining eyezm.
Unfortunately, I don't know of anyone who actively develops zoneminder who also uses eyezm.
I don't own a tablet and my personal phone isn't "smart" so I am not able to directly contribute to this.

The only thing I can offer is to help coordinate changes into zoneminder if someone else does the work.

[Lars]

Is the source available for the mobile app?

[iconnor]

sipi your buffer prolems are because you went from an 8it palette to a 24 bit palette, this requires more buffers. You just need to increase them, it's on one of the tabs in the monitor config.

[knight-of-ni]

We just had someone volunteer to develop a mobile app for zoneminder.

If you are interested, please read this thread here on github:

Feedback is appreciated.
