Upgrade to ARC Pro

Synthiam ARC Pro is a cool new tool that will help unleash your creativity with programming robots in just seconds!

@DJ, you are on a bug zapping roll. Have you had a chance to look at stripping the weird header data from the Foscam mjpeg stream. (I will admit I haven't tried it after the last few releases since it wasn't in the release notes, so you may have already done it) .

I would like to remove my camera from the internet if you don't need access anymore, and I am really hoping the fix will also fix the same error that we get in the Acer W3 tablet cameras.


The Foscam one day may have a driver in ARC and is on the list. Albeit moving lower down ;). Maybe someone with C# plugin ability will be able to assist your needs?
You're going to get me to learn C# yet;)

No problems. This is very low priority for me. I am going to unforward the port in my router, just let me know whem you want to work on it and I'll renable it so you can test without buying a Foscam.
