Hello guys,
I've got a strange problem here. What I try to do is creating code for the real-time windows target from a model that use the "from video device" block (which is able to generate code, see http://www.mathworks.de/de/help/imaq/fromvideodevice.html), the "blob analysis" and the "optical flow" blocks.
The compiler error is:

so it seems there is only a problem with the linker due to multiple definitions in the blocks' s-functions. But I don't know in which files and whether i can modify them.. I recognized, that if I remove one (random) block of the three the model compiles.
Any help is appreciated ;)
Thank you, Jan

It is not possible to use the "From Video Device" block with Real-Time Windows Target. Although this block generates code, the generated code depends on Win32 API that is not present in the Real-Time Windows Target real-time kernel.
An alternative could be to use Real-Time Windows Target in Normal Mode and to run the model uncompiled. This way there will be no problems with using the block if the performance of Normal Mode is enough for your model.

Thank you very much!
The problem is not only the performance (I think it would be ok in normal or in accelerated mode) but the timing. We are using the camera and other sensors located connected via RS-232 to localize a moving object and trying to use simulink with the real-time target as a close loop controller. So we need a good time base. In real time mode we can simply use the 'simulation time', in normal mode this isn't possible afaik?
Thanks, Jan

Normal Mode models run synchronously with real time when you place the Real-Time Synchronization block into the model. This feature is available starting with MATLAB R2012a.
So the Real-Time Synchronization block may be all you need.

Hi everyone,
I'm actually trying to use Simulink Real Time video blocks to get the video on the target computer using a Logitech webcam, the link between the host and the target computer is already done and works fine.
The problem that I faced is that I got errors when trying to see the video on the target monitor. Here are the two errors :
- Video device is not found (even if the Logitech Webcam appears in the USB Video Device List).
- No UDP channel free or UDP error.
I will add the model that I made in the attached file, hoping to have some help from the mathworks community.
