Dari kesibukan yang memusingkanku dan segudang tugas yang bertumpuk, aku mencari
beberapa file multimedia untuk diputar dan menambah “bosan” suasana. Beberapa file
berformat .avi .??? dan lainnya yang membuat pusing tidak akan bisa dijalankan dengan
program windows media player standar yang dibawa oleh Microsoft Windows, terkadang
orang perlu menambah sofware lain seperti _[Quick Time](http://www.apple.com/quicktime/download/)_
dari Apple, atau _[Real Player](http://forms.real.com/netzip/intl/intl_getrde601.html?lang=en&h=software-dl.real.com&f=windows/installer/R41APD/RealPlayer11GOLD.exe&p=RealPlayer&oem=rp11_en_ap&src=freeplayer_partner,112206focus&tagtype=applet&type=rp11_en_ap)_.
Tentunya itu akan cukup memakan banyak tempat di hardisk kita, yah … apa boleh buat
memang begitulah caranya. Namun beberapa tips sederhana bisa dilakukan dengan menambahkan
codecs ke dalam sistem operasi Windows.

Apakah itu _codecs_? Mungkin cuplikan berikut yang saya ambil dari sebuah FAQ bisa
membantu, “_Most players use DirectShow for playback. DirectShow is a system that
uses multiple DirectShow filters as building blocks to construct what is called 
a DirectShow graph. A file is a root of this graph and the audio and video renderers
are the leaves of the graph. During playback data flows from the root to the leaves.
Each filter in the graph performs a subtask of the whole process. Typical elements
in the graph are a source filter, also called a splitter, and decoders for the audio
and video. A source filter is responsible for reading the file format and feeding
the data to the other filters downstream in the graph. During graph creation, if
DirectShow finds multiple filters that are able to perform the same subtask, then
it will typically select the filter that has the highest merit. The merit of a filter
is simply a numerical value that indicates the preferability of the filter. Tools
exist to alter the merit of a DS filter. Advanced players are often able to manipulate
which filters are used in the graph, allowing for example to block or prefer certain
filters. If no suitable DirectShow filter can be found to decode a certain audio/
video format, then DirectShow is able to fall back to using VFW and ACM codecs (
see below) through special wrapper filters. It is a myth that filters can ‘conflict’
with each other. If something goes wrong it is simply because some filters in the
graph are not performing their subtasks correctly. The filters in this pack are 
carefully selected to provide you with optimal functionality and a minimal chance
of running into problems._

_Codec is short for ‘compressor-decompressor’, a piece of software that is able 
to decode and encode a certain format. By this definition, a DirectShow filter is
not a codec._

_Two other systems are VFW (Video For Windows) and ACM (Audio Compression Manager).
Components for these system are called codecs, because they are typically able to
both encode and decode. These two types of codecs are required by most video editing
applications, such as VirtualDub. Traditional video editing applications are not
able to use DirectShow. More modern applications are sometimes capable of using 
DirectShow for decoding, but they usually still require VFW and ACM codecs for encoding._”

 

Ha… ha…, emang bikin pusing, tapi sederhananya memasang _utility_ yang bernama _codecs_
ini membantu kita membaca dan memutar berbagai berkas multimedia. Salah satu yang
kusarankan adalah KLM-codecs dan bisa diunduh secara gratis dari internet. Well,
semoga menikmati ber-multimedia-ria…. (jika kurang silahkan mencoba mencari di [http://www.free-codecs.com/](http://www.free-codecs.com/)
untuk program sejenis lainnya).
