Title says it all - does anyone know of a Java implementation of the JBig2 decoder?

A little bit of Googling leads to a decoder written by the JPedal guys who apparently wrote a JBig2 decoder for use in their PDF rendering and open.
Google learns me that there's one from JPedal.

Anyone know a QR decoder that works on mac or that might be online? I just need to decode one single image.

You need the developer.
Found http://www.drhu.org/QRCode/QRDecoder.php
This online decoder may also work for you:
ZXing Decoder Online
I managed to compile qrencode 2.0 a few months ago on my iMac.

Hi,
Does anyone know for any good resource on the web or book where the explanation for Viterbi decoder or a tutorial on how to decode a received bit sequence by using trellis diagram could be found?
Thanks!

How cool.
There is actually a website which will generate viterbi decoder software for you.
Information.

I use the pcapy / impacket library to decode network packets in Python. It has an IP decoder which knows about the syntax of IPv4 packets but apparently no IPv6 decoder.
Does anyone get one?
In a private correspondance, the Impacket maintainers say it...

According to libpcap changelog , version 1.0 released on October... .
As the pcapy page states it is not statically linked to libcap, so you can upgrade to a newer one with IPv6 support .
I have never used pcapy before, but I do have used libpcap in C projects .

Hi everyone! How can I implement a Serialization Proxy that can be used with a XMLEncoder/Decoder? The classic one (the Bloch one, I mean) doesn't work...

Answer Snippets (Read the full thread at stackoverflow):
The original Java serialization mechanism allowed objects to control their own serialization and deserialization... .
However, that will be painful, and may not give you what you want .
The short answer is that you need to write a front-end that manages serialization .

Hello,
How do we get the performance of a video decoder as to how many frames it can decode per second. I know following parameters are used to arrive at fps but not able to relate them in a formula which gives the exact answer:
seconds taken to decode...

For example, when we say a codec takes 100 MCPS on a given processor... .
This parameter describes the performance of any software on a given processor .
Million Cycles Per Second.
When a codec quotes a MCPS number it is for a specific hardware configuration .

Does anyone have a nice code snippet for a Guid to Base34 encoder/decoder, I've googled around for it previously and never really found any good sources.

Answer Snippets (Read the full thread at stackoverflow):
Encode:
string encodedGuid = Convert.ToBase64String(guid.ToByteArray());
Decode:
Guid guid = new Guid(Convert.FromBase64String(encodedGuid));
This Number base conversion class....
The key methods here are ToByteArray and this particular constructor .

I am trying to use sun.misc.BASE64Encoder/Decoder, but this code:
(new sun.misc BASE64Encoder()).encode(new sun.misc.BASE64Decoder().decodeBuffer("test string XML:"))
returns "test/string/XML/" I am embarrassed
Answer Snippets (Read the full thread at stackoverflow):
Use commons-codec Base64.encodeBase64(..) and Base64.decodeBase64(..)
I think you want:
String s = "Hello world"; new sun.misc.BASE... .
They are not guaranteed to be consistent between different versions of the jre .
Don't use sun.misc or com.sun classes.

I am looking for h264 decoder C/C++ source code with RTP packetization support. My embedded device is sending 640x480 encoded h264 RTP packet. I would like to make a Windows XP/Vista based video streaming display.
Where can I find the source code to this...
Answer Snippets (Read the full thread at stackoverflow):
RTP packetization is supported, and there are both an encoder and a decoder..
You should take a look at the h.264 reference implementation .
There might also be patents on the decoder.

Hi, I am having trouble trying to understand some viterbi decoder source codes. I understand the concept and everything but I just don't get some of the calculations that appears in viterbi decoding as well as how convolution code works in the source ...

Phil Karn has C implementations of several forward error correcting algorithms... .
Not in C, but highly recommended to understand the algorithm .
NLTK has a fully functional Viterbi parser written in Python, including a demonstration application on how it works .
