MSRS on CE 6?

I have a DSS service I created (For Microsoft Robotics Studio). I then followed the documentation to make it a compact framework service and created a deployment package. I then deploy it to a CE 6 device... Does a MSRS service work on CE 6? The documentation talks about CE 5? What should I see if I run it? I expect to see something sim...

MS Robotics Studio: "contract is different from that of the namespace"

I'm trying to build a DSS service using MS Robotics Studio and VS 2008, but when I build, I get an error from dssproxy.exe saying: The class MyServiceName has a ContractAttribute but the contract is different from that of the namespace. and the build fails because dssproxy returns code 10. Does anyone know what this message means...

creating mobile streaming server (3gp)

I need an Open Source solution & tutorial for creating mobile streaming server that can stream video on 3gp (3gpp) format, i have tried using Helix DNA Server, but it's free version only allow real media not 3gp. I have heard about DSS (Darwin Streaming Server) but i can't found any Windows binaries (compiled exe) for that, and Catra St...

Setup for MS Robotics Studio on 64 bit WIndows

How does CCR & DSS toolkit model compare to other scalability & concurency approaches?

I'm interested to comparison between various approaches to scalability & concurrency including CCR & DSS framework model. I would be especially interested with comparison with Hadoop and Erlang style concurency ...

Darwin Streaming Server doesn't gives content

Hello! I have problems with Darwin Streaming server 5.5.5 on Debian. When i'm trying to open some stream, for ex. rtsp://sample.com/sample_100kbit.mp4 player reports it can't load stream and breaks connection. "Access History" section reports file was requested, so, at least initial connection is working, but nothing more. What can be w...

Parsing X509 DSS Certificate to get P, Q, G and Y

I am trying to parse a X509 Certificate that contains a Digital Signature Algorithm (DSA) public key. Using the javax.security.cert.X509Certificate class and getPublicKey() method I've been able to get P, Q, G and Y: P: 0279b05d bd36b49a 6c6bfb2d 2e43da26 052ee59d f7b5ff38 f8288907 2f2a5d8e 2acad76e ec8c343e eb96edee 11 Q: 036de1 G: ...

Mathematical attack on the Digital Signature Algorithm

Does anybody know the mathematics behind an attack on DSA where modulus p has p-1 made up of only small factors. In reality, this would not happen as the key generator would guarantee that this is not so. There is much information on the web on generating good input paramters for DSA so that it is hard to crack but no information on ho...

Is it possible to stream live using mod_h264 / pseudo streaming ?

I have Icecast and Darwin Streaming Server configured and running. Serving HE-AAC live radio. How can i utilize mod_h264 or other pseudo-streaming technologies to relay that stream to web page (with flowplayer or smth) ? Thanks in advance. ...

Worked Example of Digital Signature Algorithm

Hi Folks, Does anybody have a DSA worked example with simple values on how to calculate r,s and verify v == r. As this standard has been around awhile and is implemented in librarys e.g. the Java Cryptography Extension I'm finding it very hard to find an example of how the algorithm works. Compute r=(gk mod p) mod q Compute s=(k-1 * ...

DSS won't stream 3GP's encoded with FFMPEG

I have setup Darwin Streaming Server which streams the included sample 3GP files pretty well. However when I try to encode my own 3GPs using FFMPEG and stream them, it doesn't work. (I test the streaming using VLC Player). Here is the command I use for encoding: ffmpeg -i test.flv -acodec aac -ar 22050 -ab 128kb -vcodec mpeg4 -b 256k -...

How to use CCR, DSS, VPL (aka Microsoft Robotics Development Studio) outside robotics?

How to use CCR, DSS, VPL (aka Microsoft Robotics Development Studio) outside robotics? I am looking for guidance in this field. I have tried all the examples and find the framework intriguing. Can anyone post other uses and examples, outside robotics? PS. I am looking for someone to explain some of the more complex stuff to me. I have...
