Video Codec In Matlab project

Video Codec in Matlab project help. 

Perhaps you have come across a situation where you have downloaded a video from the internet, and it failed to play on your PC. What could be the problem? Few care to ask, and the immediate answer that most people assume is the file was not correctly downloaded because of a poor internet connection. However, have you ever thought that the problem could be the codecs? This sounds rather mysterious. Few have come across this word before. This article will help you demystify this and will prompt you to avail of video codec in Matlab project help. 

Video codec 

Video codec refers to a software or an electronic circuit that compresses and decompresses a digital video. The name codec comes from merging two popular terms- encode and decode. Encoding in this context means to convert a digital video file from one format to another. A device that compresses files is known as an encoder. On the other hand, a video decoder decompresses a video. Some codecs might omit one of these components. Generally, a video codec is normally identified by a four-character code. Examples are MPEG and HEVC.

Video compression has to conform to certain video specification standards. Whichever video specification standard is used, in most cases, the compression is lossy – some of the information in the compressed video could be lost. As a result, a compressed video will have a low quality than the uncompressed video.

History of videocodec.

The need for a method to reduce the amount of data used to store a raw video started when compact disks were introduced in the market as a replacement for analog videos. Traditionally videos were stored in magnetic tapes. With the introduction of compact disks, it was  possible to store and work with  videos in the digital form. However, there was a challenge in the amount of data needed to store the digital video. This prompted a lot of scientists and mathematicians to focus on achieving solutions, which involves compressing a digital file.

The first success of a codec came in when the discrete cosine transform was introduced in 1974 by T. Natarajan, Nasir Ahmed, and R. Rao. In the 1980s most companies started experimenting with it, leading to the development of H.261 as the video coding standard. This was the first video coding standard. The discrete cosine transform was adoptedby mostof the video coding standards that followed the H.261

File formats vs. codecs

A file format is a typical container that has different file formats. Inside the container, it is possible to find files that have been compressed by a specific codec. Normally, a container can contain a video, audio codecs, and in some cases, other files like chapters and subtitles. The common examples of video formats are MP4, MKV, MOV, and AVI. Common examples of video codecs are HEVC, XVID, H.264, and MPEG codecs.

Codec Matlab.

Matlab is a programing language, initially developed by Mathworks for numerical computations. It has advanced, and now it can perform matrix computations, develop the various plots, implement algorithms, and interface with other programs. Matlab provides you with everything you need for analysis. Matlab enables you to load a video in its platform and decode or encode it. The Matlab functions that you can use for this process are VideoReader and VideoWriter.
