Format Error?

[hitman80]

I have a question for Synology's Team or other geeks .

For a few day I can try some Ipcameras , but I have a problem about video path on Synology Surveillance menù.

I'm sure that video path of my Ipcamera is correct .

This is the info from manufacturer :

http://<servername>/cgi/mjpg/mjpeg.cgi

These tests show that video path is correct :






But when I configure Synology Sureveillance menù about VIDEO PATH with cgi/mjpg/mjpeg.cgi , I obtain this strange error :




Why ? Any suggestions ?

If I read that error message correctly, it roughly translates into "image format not valid". Please try adjusting your camera resolution (in your Camera Settings, NOT the Surveillance Stations Settings) to 320x240 or 640x480, set the FPS to 10.


Hope this helps

i have not tried the surveilance station
but as i understand it .. and see your pictures

1. picure.. you dont' get a picture from your browser either with the /cgi/mjpg/mjpg.cgi

2.picture works.. with the "/admin/view.cgi?profile=/cgi/mjpg/mjpg.cgi"

try the line 2 in your surveilance station
the NAS probably works as a "browser" so get the line to work in a browser (as in 2)

2.picture works.. with the "/admin/view.cgi?profile=/cgi/mjpg/mjpg.cgi"

I've just tried it and similar path .... but it's always shown the same errore " image format not valid"

Please try adjusting your camera resolution (in your Camera Settings, NOT the Surveillance Stations Settings) to 320x240 or 640x480, set the FPS to 10.

I 've tried to change camera resolution from VGA,QVGA or QQVGA and FPS from auto , 25 fps to 10 fps .... but same error ...

I will try again in the next days ... I'll do it

I can add this info about Manufacturer of Camera :

Some infos about how to use scripting in CGI Command of Network Camera.
This CGI Command document specifies the method of communication with the Network Camera for controlling camera functions as well as for getting and
setting internal parameter values, which helps the application integrators develop software applications more easily.

I noticed in your second picture that you have the ability of adjusting the camera compression between MPEG-4 and MJPEG; perhaps this can be the cause of you error?

Also, try the following code in your video path, it is similar to the original format, except with a "forward slash" in the path name

Code: Select all

/cgi/mjpg/mjpg.cgi

Note, I'll have one of our NVR developers look at this thread as well.

Hi Franklin ,

I have also done these tests without success .

I tried to change video path following your advice : /cgi/mjpg/mjpeg.cgi , and this is the error shown :




so i changed compression from MJPEG to MPEG-4 , but the problem is the same :

I have a simlar problem with VIVOTEK IP Cams I am trying to inatall the source path is :"/cgi-bin/video.jpg" but keep getting an Authorization Failed error 4

@hitman80
Please tell me the make and model of your camera, one of our NVR developers would like to perform more research for you.

@Dark Shadow
Please ensure that the username/password of your camera matches the credentials you add in the Surveillance Station interface

You may also wish to direct your conversation to our beta support team, please look here

Ok . This is a similar IPCAMERA tested : UNC7400-IRW

http://www.eusso.com/Models/Network_Cam ... 00-IRW.htm

In order to understand if the problem could be video path , I have tried to use the following demo-program of video surveillance ACTIVE WEB CAM :

http://www.pysoftware.com/

I have created a NEW CAMERA :



and I have correctly configured demo-software , adding this video path --> /cgi/mjpg/mjpeg.cgi



Demo-software with /cgi/mjpg/mjpg.cgi works perfectly .

Can you use VLC Media Player to view the streaming video of your camera? Our engineers believe that either there is a path error, or their mjpeg is slightly different from the mjpeg standard, so it may not be compatible.

What bad news !!!

I tried with VLC PLAYER with this video path /cgi/mjpg/mjpeg.cgi and DOESN'T WORK .....

Video isn't shown








Is there a solution ? Can Synology resolve the problem ? Or It needs to ask also to Manufacturer of IPCAMERA ?

I suppose that there is a lot of IPCAMera similar to my Ipcamera .... It is a pity ....

[Franklin]

Greetings hitman80

To resolve this error, you will have to contact the manufacture of the camera to determine what is the exact path to the video, or are they using a modified version of the mjpeg standard. If they give the path and it still does not play in VLC Media Player, then their mjpeg specification is not standard then the official specification, and unfortunately incompatible.

The SynologyWiki will be updated to reflect this.

@ Franklin

Can I ask an information ?

I tried to use VLC PLAYER with other my IPCAMERA that perfectly works (DIGICOM IPCAMERA WAVE 54 ) with video.cgi as video path, but VLC doesn't reproduce anything .... Why ?

I think I did a good configuration about VLC settings , but also in this case video isn't shown .

Maybe I'm wrong

Can I receive an example of a configuration of VLC PLAYER to see VIDEO of IPCAMERA ?

Greetings hitman80

The video path from the Surveillance Station interface is different from the "true" web path. Usually, most cgi scripts have attributes after the cgi extension, and that's where other variables are added, such as resolution or frames per second. If you refer to the attached images, you can see this "path difference" from the Surveillance Station and from what path is used in VLC Media Player





For your camera which doesn't work, if you figure out the exact "true" path, try that in Surveillance Station, and see if that will work. Please note that you will have to set up your camera before you can use the "true" path, such as defining maximum resolution, or level of quality, etc...

Note: I am using VLC Media Player 0.8.6d

Hi,

I am able to view my WVC54GC video with VLC Media Player. Inside the Stream And Media Info, it stated that the video codec is MP4S. However I still get the same invalid format error from Surveillance Station. So is MP4S format supported by Synology?

BTW, I upgraded my DS108j firmware to DSM2.0-0702. I was thinking the new firmware could solve the problem but it didn't.
