I've commented the code. I'm just slightly confused as to why you want to run it on Ubuntu especially since we all got tiny little 2Go computers with XP.

For my team, this seemed to cennect unreiable. The fps was below 5, and you had to resart it several times for the video feed to come. Do you have to turn off firewalls, or do something special? We are running this off a computer connected via usb to ethernet adapter. to a windoes XP professional machine.

thats about the bandwidth of USB, sorry, but you guys are SOL

I ported (different front end) this to .net 2, and integrated it with our ZomB Dashboard, which you can download here: http://www.chiefdelphi.com/forums/sh...d.php?p=931845
It gets the same as the original, but easier for non WPF users (like Ubuntu users) to use.

What on earth do you mean by that?

I had a question for Dominis regarding that.

As far as I can tell I get around 5 FPS as well, with the stock dashboard OR his dashboard.

That makes me believe that the framerate you see on your dashboard is also affected by the framerate the crio is processing.

I wonder why that is if it's the case - couldn't we decouple the two and have new pictures sent to the dashboard as quickly as possible while doing the image processing in a parallel loop? I'm going to post the question for the NI guys because I don't see any obvious reasons it wouldn't work.

I've gotten 30 fps running on TheDominis's dashboard on a laptop besides the Classmate. The entire reason the FPS is slow low is because the Classmate's processor is too slow to handle the image processing any faster. The bottleneck is not in the cRIO, but the Classmate.

I'm developing my own video display (using C++ instead of a .NET language) with some hardware acceleration (Direct3D 9). I'll let you know if there's any speed increase.

I use my dashboard on the classmate and get 30+ FPS...

[Robototes2412]

Can you please make it wine-compatible?

[TheDominis]

Sure...

It'll take me about 30 minutes or less...

or maybe longer... not much though

my ZomB .net 2 port *SHOULD* be mono AND wine friendly (have not tested however)

EDIT: Mono migration tool says one error, but it is easily fixed, I'll post a mono-friendly version in about 3 minutes. void Receiver_OnImageUpdate () Image Image.FromStream (Stream, bool, bool) useEmbeddedColorManagement and validateImageData aren't supported.
EDIT2: posted at above url

I have ported the video dashboard to 2.0 .NET as well as made it (most likely) Wine friendly. I also made the program more robust -- probably.

Please report any issues.

I read with some surprise the following thread:
http://www.chiefdelphi.com/forums/sh...ad.php?t=84087

I'll ask here: for the developers and users of this video dashboard, what networking setup are you using between the classmate and the machine displaying the video? Is it known to work under a real FMS?
