The codec is a software of minimum size, which is used to encrypt and decrypt files , offering the user to reduce the size of the media file, without decreasing their quality.
Most codecs typically encode the signal, and then decrypt it when you play it, which was altered in a different format which had been codified. A clear example is that of a media file, which initially weighs 30MB, which is compressed and then decreases in size to a rapprochement between 3MB and 4MB, which maintains overall quality when playing.
Among one of the most famous is the MP3. In offering an example, a song is compressed in MP3 format occupies 3MB to 5MB, without losing audio quality, while an uncompressed equivalent to ten times.
In conclusion the codec has the vital function of minimizing a file without harming the quality loss. The user must have installed the specific codec to decompress video, audio, or any other file you want to use, because each codec compresses each file differently. Thus originates a great number of codecs, which improves in quality or in compression when encoding a file.
If in case the user does not have the right codec to open a file, the system can play it hard, because it requires the user to know which codecs required, which will be used for exclusive software to analyze the computer , which will show the codec that is needed, or just show us where the problem is.
The following will detail two programs , which will be helpful for the user:
VideoInspector: This program will allow the user to obtain detailed requirements required codec, and also provide a link where you will find the codec searched. To proceed to install it directly, only due to enter the above mentioned website.
GSPOT: This program, like the previous one, find and detail the required codec. To get it, you can directly enter the mentioned website and download it for free, or visit the official website of the product.
One of the problems that can result when you install a codec pack, is the loss of computer performance, because it may conflict with another codec pack that is in the PC. Therefore it is recommended that the user install only the codecs needed and could be increasing them as they come out other new formats.
