MPEG-1 is used to transmit 1.5Mbps data transmission rate digital storage media motion image and its sound code, after MPEG-1 standard compression, the video data compression rate is 1/100-1/200, the audio compression rate is 1/6.5. MPEG-1 provides an image of 30 frames per second 352*240 resolution, and is close to the quality of th
Install MPEG-1 Layer3 (mp3) decoder, mpeg-1layer3 on Linux
Today, I suddenly wanted to play music on linux, but I found a decoder missing when I started it.
So I went to the Internet to find a solution, which was so messy, but a post provided a very simple method.
The following content is reproduced on the Internet
The above prompt shows that no decoder is installed. This is because the software d
MPEG is short for MovingPictureExpertsGroup. The original meaning of this name is a group that studies video and audio encoding standards. What we call MPEG now refers to a series of video encoding standards developed by the team. The Group was formed in 1988, so far has developed MPEG-1, MPEG-2,
Most MPEG movie files downloaded via BT have bad data, causing problems such as inability to play or fast-forward. How do you fix a damaged MPEG file? Here's how to fix the MPEG movie.

1. What is MPEG?
The full name of MPEG Moving Pictures Experts Group, a dynamic image Expert Group, is simply an expert group dedicated to studying audio and video specifications.
This expert group was established under the joint guidance of ISO/IEC (International standardsorganization/International Electrotechnical Commission, International Standardization Organization/International Electrotechnical Co
1 IntroductionMPEG-Ⅱ has been widely used as an international standard for motion images. Digital Video Broadcast (DVB) has used MPEG-Ⅱ as a source format. In many practical applications, including satellite broadcasting, digital cables, and high-definition TV HDTV, MPEG-Ⅱ groups are input to channels through synchronous interfaces of encoder. In the broadband digital communication network, for example, ADS

3. Application of MPEG-2
The MPEG-2 can basically meet most of the needs of the broadcast and television system, such as: Suitable for interlaced and line-by-line scanning images; and image sampling; theoretically up to 16000 pixels× 16000 lines of Multi-image decomposition force and common field and frame fre

MPEG-4 Part 2,MPEG-4 visual(Formally ISO/IEC 14496-2[1]) is a video compression technology developed by MPEG. it belongs to the MPEG-4 ISO/IEC standards. it is a discrete cosine transform compression standard, similar to previous standards such as MPEG-1 and
Ffdshow can be called the Almighty decoder, encoder. Initially ffdshow was just an MPEG video decoder, but now he can do much more than that. It can decode the video format already far beyond the MEPG4 range, including Indeo video,wmv, MPEG2 and so on. At the same time, it also provides a wealth of processing options, you can sharpen the screen, adjust the brightness of the screen and so on. More than just video, ffdshow now can also decode audio, AC3
