HEVC official software HM source code simple analysis-Decoder tappdecoder

This document records the source code structure of the HEVC official reference software HM. HM compared to JM, the object-oriented programming method is adopted, so the structure is relatively clearer. HM contains the video decoder Tappdecoder and the video encoder Tappencoder. This document records the structure of the video decoder Tappdecoder.Function call graphThe function call diagram for the HEVC vide

What is real decoder?

What is real decoder: The real decoder is a rip out of the RealOne, in short, by installing the real decoder, you can play real-format audio and video files without installing RealOne or RealPlayer. The mainstream media players such as Media player, media Player Classic, Zoomplayer, and so on are able to play real files through real decoders. In addition, the re

Installing the MPEG-1 Layer3 (MP3) decoder on Linux

Today, I suddenly wanted to play music on Linux, but when I opened it, I found a missing decoder.So went online to find a solution, said the hype, but there is a post gives a very simple method.The following content is reproduced in the networkThe above tip does not have a decoder installed because the copyright issue software does not have its own decoderThe workaround is simply to install a third-party source32-bit system third-party source: Rpm-ivh

Netty4 custom Decoder,encoder for object delivery

serialization is not very good, so many times we need to use other serialization methods, Common have kryo,jackson,fastjson,protobuf and so on. What we want to write here is not the focus of what serialization is, but how we design our decoder and encoder.First we write a encoder, we inherit from the messagetobyteencoder @Override protected void encode (channelhandlercontext ctx, Object msg, bytebuf out) throws Span style= "color: #000000;" > E

Rhel6 installing the SMPlayer player and the decoder of the video player that comes with the device

Distance RHEL7 has been released for a long time, due to my notebook's graphics card catch (710 entry level), network installation after loading black screen, engraved disk installation BIOS self-test can not pass, so also only in the real machine installed rhel6.5, VMware under the RHEL7 to experience. No more nonsense, get to the point.Red Hat application in the server does not need to say more, but every time you want to play video on it, always error, and then click Download, error, even if

Create an MP3 decoder-use mad (MPEG audio decoding library) in Symbian

Create an MP3 decoder-use mad (MPEG audio decoding library) in Symbian Some time ago, I wrote a program on newlc.com to create an MP3 player for Series 60. I have received many emails about MP3 decoding and using it on Symbian. Here, we use mad (MPEG audio decoding library) in Symbian to solve the problem. Overview Because in Symbian 7.0, you can use MMF to play MP3 videos in smartphones. However, if your mobile phone does not support MP3 decoding, o

Implementation of cabac hardware accelerator in H.264 decoder

In H.264 decoder, the implementation of cabac hardware accelerator H.264 has two kinds of entropy encoding solutions: one is context-based adaptive variable-length encoding developed from the variable-length encoding solution, and the other One is context-based adaptive binary arithmetic code cabac developed from arithmetic coding. Compared with cavlc, cabac can save about 7% of the bitstream, but increase the computing speed by 10%. . When decoding h

Theoretically, as long as the corresponding decoder is installed in the operating system, the corresponding media can be supported.

himself. The installation interface, menu, and dialog box are not very standard. Now commercial software operations are getting more and more similar, and users are easy to learn. In addition, if the architecture of the solution is open, how can we not automatically download the module to install new decoder, patch, and other automatic update software? (I bought two patches in less than a month for the solution 2002.) Check realplay. mediaplay automa

Dolby decoder downmix (LO/Ro and LT/RT)

From the Dolby metadata guide:In each of these devices, the analog stereo output is one of two different stereo downmixes.One type is a stereo-compatible Dolby Surround downmix, of the multichannel source program that is suitable for Dolby Surround Pro Logic decoding.This kind of downmix is also called Pro logic or left total/right total (LT/RT ).The other type is a simple stereo representation (called left only/right only, or Lo/RO) suitable for playback on A Stereo hi-fi or on headphones,And f

TDECCU part of the HEVC decoder

This article, "HEVC decoder flow," gives the overall flowchart of the HEVC decoder, which is mainly for the TDECCU part of the explanation.The TDECCU entrance has two main parts: The DECODECTU is the entropy decoding and the inverse scan, and the other part is the DECOMPRESSCTU, which accomplishes the functions of prediction, inverse quantization, inverse transformation and reconstruction.The specific flowc

[Serialization] An example of FPGA-based 6-segment display decoder-8-3 BCD

[Serialization] FPGA OpenGL series instances 8-3 BCD seven-segment display decoder in the format I. Principles The 7-segment digital tube uses a combination of different light-emitting segments to display different digital data. To try the digital tube to display the numbers represented by the digital, you must translate the digital data into a decoder, then the block used by the drive is illuminated.

uses the GetChar to be suitable.2. When using TOASCII to obtain a number at the time of submission, the hint is WA.#include define function: int toascii (int c);Function Description: Toascii () converts the parameter C to a 7-bit unsigned char value, the eighth bit is cleared, and the character is converted to ASCII characters.Return value: Returns the converted ASCII character value for success.Example: Convert int A to assii code character.j = toascii (Buf[i])-7;If you use this, the compilati

How to install an internal decoder for a format factory

1, first we find the local format of the factory program, the software we double-click Open, direct Access. 2, in the upper left corner we find the choice of words, directly click to enter on it. 3. Switch to advanced option settings on the left. 4, click on the installation of internal decoder to the system, click on the installation is good. 5, we can choose the installation, we install right click on the menu, that i

[Serialization] FPGA-based SSD series instance-3-8 Decoder

[Serialization] FPGA OpenGL series instances 3-8 Decoder Based on OpenGL I. Principle: Decoding is the inverse process of encoding. Its function is to identify binary codes with specific meanings and convert them into control signals. A logic circuit with decoding function becomes a decoder.The decoder can be divided into two types:CodeConvert to one of the valid signals. This
