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.

Base64 encoder/decoder [Java version]-post

Http://www.javaidea.net/list.jsp? Topic = 5 Author: Home cat Base64 encoding is a common character encoding, which is used in many places. JDK provides very convenient base64encoder and base64decoder, which can be used to conveniently complete base64-based encoding and decoding. The following are two small functions compiled by myself for base64 encoding and decoding: // Encode s with base64Public static string getbase64 (string s ){If (S = NULL) return NULL;Return (new sun. Misc. base64encoder

Audio/Video Decoder

The previous project was dealing with many codecs and had a lot of conceptual confusion. Now we have recorded the relevant reference addresses: Decoder list Http://en.wikipedia.org/wiki/List_of_codecs List of open source file codecs Http://en.wikipedia.org/wiki/List_of_open_source_codecs List of audio and video codecs implemented by FFMPEG Http://en.wikipedia.org/wiki/Libavcodec Related Concepts: lossy compression vs lossless compressio

Recently, a MIDI source + decoder filter was blocked.

Some time ago, I performed Windows CE multimedia development and found that there was no MIDI filter in Windows CE. Recently, I was quite empty. I encapsulated it and ran it. Some details need to be sorted out, then I will share it with you in my resources. In addition, we have recently developed video for CE/mobile. The ddraw supported by the sub-host in Mobile 5 is only 0xc0, that is, only one primary surface is supported, the format of the current deco

Supor's JPEG decoder [2]

The part of the Harman decoding and bitstream operations. JPEG's Harman encoding is optimized. For every n-bit long encoding, if it is smaller than Max [N], it is an end encoding. Max [N] can be calculated based on the code table given in the DHT syntax. The bit retrieval method is common. If Assembly optimization is used, you can consider using the implementation method of the image decoding program in a H-GAME that was previously tracked. I will not talk about it here. Note that rstn may be in

FFDShow MPEG-4 Video Decoder rev1019 download

FFDShow can be called an all-powerful decoding and encoder. at first, FFDShow was only an mpeg Video Decoder, but now he can do more than that. the video formats that can be decoded are far beyond the mepg4 range, including indeo video, WMV, and mpeg2. at the same time, it also provides a variety of processing options, you can sharpen the screen, adjust the brightness of the screen and so on. more than video, FFDShow can also decode audio, AC3, MP3, a

Deep Learning for Color Image Feature Extraction: Linear Decoder

Label: style blog HTTP color Io AR for SP data In the previous discussion, all the incentive functions used are sigmoid functions: We assume that the output range of the final output layer is [0, 1], and the motivation of Self-encoding learning is to make the output equal to the input, so all input must be adjusted to the range of [0, 1, however, the problem is that the input range of some datasets is easy to adjust, such as minist, but the input of PCA whitening processing does not meet

Canonical explains the reason why Ubuntu uses a disabled source H.264 decoder

In recent disputes over H.264 patents, some observers noted that Ubuntu commercial sponsor Canonical had been included in MPEGLA's H.264 authorization list. Canonical is the first Linux release developer to obtain the controversial H.264 codecs. Canonical tries to clarify why it wants to obtain a closed-source patented decoder for a computer preinstalled with Ubuntu. Users who manually download and install the Ubuntu release still use free software. T
