Here are answers to some common questions about codecs.
1, What is a codec?
A codec is software for compressing or decompressing digital media files such as songs or videos. Windows Media Player and other programs use codecs to play and create digital media files. A codec can consist of two components: an encoder and a decoder. The encoder performs a compression (encoding) function; the decoder performs a decompression (decoding) function. Some codecs contain both components; some codecs contain only one of them. For example, when you rip a song from an audio CD to your computer, the player uses the Windows Media Audio codec to compress the song into a WMA compressed file. When playing this WMA file (or any WMA file that comes out of the website), the player decompresses the file using the Windows Media Audio codec so that the music can be played through the speakers.
2, which includes player codecs?
There are currently hundreds of audio codecs and video codecs in use. Some of these codecs are created by Microsoft, but most codecs are created by other companies, organizations, or individuals. By default, the Windows operating system and player include many of the most commonly used codecs, such as Windows Media Audio, Windows Media Video, and MP3. However, sometimes the content to be played may be content that is compressed by a codec that is not included by default in Windows or the player (for example, a file compressed with the DivX video codec or Ogg Vorbis audio codec) . Because the player is expandable, in most cases the necessary codecs can be downloaded from the website for free or for a fee. In some cases, the player can automatically use a codec installed by other digital media playback and creation programs on the computer.
Some codecs are available for download from the WMPlugins.com codec web page.
3, why there were indications that computer is missing a codec?
If the resulting message indicates that the computer is missing a codec, the files that you may be trying to play, burn, or sync are compressed by a codec that Windows or the player does not include by default. In most cases, you can download and install the missing codecs by clicking the Web Help button in the error message dialog.
4, What is a DVD decoder?
The DVD decoder is also known as the MPEG-2 decoder. The content on the DVD-Video disc is encoded in MPEG-2 format, just like the contents of a DVR-MS file (Microsoft recorded TV show) and some AVI files. To play these items in your player, you need to have a compatible DVD decoder installed in your computer. If your computer has a DVD drive installed, it may already have a DVD decoder installed. However, if you encounter an error message indicating that a compatible DVD decoder is missing, click the Web Help button in the error message dialog to determine how to obtain a compatible DVD decoder.
5. Why can't files played at home be played in the office?
This can happen if the codec installed on the computer in your office is different from the one on your home computer.
For example, if you try to play a DVD-Video disc or DVR-MS file on a computer in your office, but the DVD decoder is not installed on the computer, you won't be able to play this until you install compatible on your computer in the office. DVD decoder.
6, I have a missing codec installed, but still can not play the file. why?
for 32-bit or 64-bit operating systems, the codec is writable. If you are running a 64-bit version of Windows, you must install a 64-bit codec. For example, if you install a 32-bit codec on a 64-bit operating system, your player might not be able to play any files that require that codec.
Please note that many older codecs are only available on 32-bit versions of the operating system. If the codec provider does not specify whether its codec is 32-bit or 64-bit, the codec is likely to be 32-bit. Contact your codec provider for more information.
