hi
Im interfacing to a Sony IPELA video camera that has a built in http web server. i can send individual HTTP commands to authenticate, to retrieve still jpeg images from the camera and to control tilt pan zoom. but when i initiate video, there is nothing, the bits fall onto the floor.
As a result of searching it seems that software related to web cam applications is needed. I thought how about Labview? is there a way to make an object that will consume an RTP video stream? it can be H.264 or mjpeg or mpeg4
thanks so much

ok, so far i found out that only "mjpeg over http" is supported in labview using the imaq dx? I'm looking for examples of this.
A standard web browser can display the video, but so far i was told labview cannot.
And that labview cannot do UDP video streaming using RTP. so that question is answered, no UDP over RTP but mjpeg over http is supported, but have not found examples, anyone know of examples?

ibradleyallen,
This article that says Axis and Basler cameras are supported by IMAQdx in the Fast Ethernet (IP) section
http://digital.ni.com/public.nsf/allkb/4331B4AA3AE95233862574C200539A2F
It does not mention if these are the only exclusive brands or not. What is the full model number of the sony camera you have? If it is GigE Vision compliant then IMAQdx will support it.

Hi
I know it is an old one, but have you found a way to display and control the video stream from your Sony camera?
I have now simmilar problem and have to interface to Sony SNC-EB600B, which is also IPELA engine. Have been looking for the answers/drivers in the forum but nothing so far. Perhaps you were more lucky than I.
Can you share snippets of the code to talk to your camera?
thank you in advance

hi
Sony has some boilderplate/example code that runs in visual studio, your Sony rep for this camera should be able to send you the latest. i might be able to find the older stuff but its old
you setup the solution file in VS and it lets you get video and set parameters from your program. i suppose that a connection between labview and this could be made such that the .vi controls the Win32 directly, so it doesnt have to know about the Sony camera it just interfaces to the .dll but how to get the stream object and the video in the .vi ? would take time to figure out
also what we did was go with http://www.intuvisiontech.com/products/panoptes.php and now that i think about it, there is a free video software app to get the stream data but they mention it in their website, the icon has a picture of a cone? like construction zone warning cone
anyway these folks are very helpful
hth
