k-lite cannot play rm rmvb file RealAudio COOK

When I install K-Lite Mega Codec Pack 6.5.0 on WinXP SP3, Windows Media Player and Media Player Classic can play rmvb/rm files smoothly.

After I install Real Player ver 14 Hexlix Powered, WMP and MPC failed to render rmvb/rm files. It shows the following errors:

I un-install all. No matter how I change the installation steps, i.e. install RealPlay first then K-Lite, or install K-Lite first then RealPlayer, or install older version of K-Lite, or Real Alternative, the result is the same. Once RealPlayer is installed, K-Lite is broken.

Official FAQ says:
Q: RealMedia files (.rm .rmvb) freeze or play without sound

A: MPC is not fully compatible with RealPlayer 11 and 12.

or C:/Program Files/K-Lite Codec Pack/Info/faq_playback_issues.htm#item32
Q: RMVB files play without sound

A: You are probably missing a decoder for RealAudio COOK. You can install that by following these steps:

Download the Windows version of binary codec pack for MPlayer.
Extract these files from the .zip archive: cook.dll, pncrt.dll, sipr3260.dll, drv33260.dll, drv43260.dll
Put those files in this folder: C:\Windows

It seems redundant as K-Lite itself is the bundle of media libraries, why do we need to download additional binary from 3rd party? And the above steps are troublesome.

The easier way and solution is that:

1) Install K-Lite Mega Codec Pack (contains Real Alternative) or Real Alternative first. You'll see the following directory:
C:\Program Files\K-Lite Codec Pack\Real\Codecs

2) Save a copy of this [Codecs] directory. Because it'll somehow disappear when RealPlayer is installed, or you install K-Lite after RealPlayer, this folder won't exist (I don't remember clearly).

3) Then, install RealPlayer. As expected, WMP and MPC cannot play rmvb/rm properly (without sound, missing RealAudio COOK)

4) Go Control Panel -> System -> Advanced tab -> [Environment Variables] -> edit Path

Add the following path:
%path%;C:\Program Files\K-Lite Codec Pack\Real\Codecs

Adding the above path, [Codecs] folder is visiable to Windows. Now you try to play rmvb/rm with WMP and MPC, it will play smoothly again.

Search in Open Source

Sometimes I find it is quite helpless/having good life/cheating being a software engineer myself. In the daily work, I rely so much on 3rd party library. A lot of implementations are already widely available in Internet. I don't really have to do anything from scratch.

However if I am required to do from scratch? In fact I don't know how. The theory and spec can be very thick... the basic implementation can be very complicated... the simple thing itself can be a PhD project.

... ...

Anyway, the summary is, not only to search the keyword in Google. There are great developers in Japan ( and China. And maybe other non-English speaking countries too, such as Russia, just that I don't know.

How to install GCJ: GNU Compiler for Java?

In Windows world, there is no single GCJ installation.exe that installs GCJ.

GCJ exists inside Cygwin. So we have to install Cygwin. Detailed Step here:

Cygwin contains many components. It is not a good idea to install all and fill up the harddisk. How to decide which one to install?

My feeling is, choose only those components needed.

For example, I am clear that I want to use gcj ( GNU Compiler for Java ). So in the Cygwin-setup Search box, I type in “java” keyword. I choose only Devel/gcc-java.

The good thing is, when I click Next button, all the dependencies will be automatically chosen. Hence only the minimum set of components will be downloaded and installed.

When I am using gcj, along the way I’ll hit additional error, e.g. “cannot find…” missing libraries.

Error Message:
/usr/lib/gcc/i686-pc-cygwin/3.4.4/../../../../i686-pc-cygwin/bin/ld: cannot find -liconv
collect2: ld returned 1 exit status

Then, I’ll launch Cygwin-setup again to install the missing library.

Keyword to install:

Detect Brower Javascript Version

The following Javascript will show which version of Javacript the browser supports.

Surprisingly, IE8 on Windows 7 only supports up to version 1.3. No wonder some Javascripts which work on Firefox (up to 1.8), Safari and Chrome (up to 1.7) do not work on IE8.

Windows 7 and Java JDK 1.6 Timezone issue

Same piece of Java program running on Windows 7 and JDK 1.6, the date time related routine returns TIME ZONE :Greenwich Mean Time, which is wrong.

Insteads of going into source code level to add in timezome "GMT+8" routine, we can alter the timezone properties at command line level.

java -Duser.timezone="GMT+8" .....
java -Duser.timezone="Asia/Singapore" .....

Powepoint PPT to Video VCD / JPG JPEG convert conversion

If we really have to go somewhere with TV but without projector and computer, to give the presentation, how to do?

1) Convert PPT to Video DVD

There are a few Powepoint PPT to Video DVD convert conversion software. However, it seems all of them need to pay.

I am using this one:

Note: To maintain the quality, only DVD is accepted.

2) Convert PPT to picture JPEG

Most of the DVD players today can show JPEG file. So covert PPT to picture JPEG file will do also.

Note: name of JPEG file as

So that the sequence of the pictures will remain in order.
