The simplest Video Encoder Based on FFmpeg-new version (YUV encoding is HEVC (H.265 ))An example of a video encoder based on FFmpeg was created a while ago:The simplest Video Encoder Based on FFMPEG (YUV encoding: H.264)In this example, YUV pixel data (YUV420P) can be encoded as H.264 code streams. Because FFmpeg now supports libx265, the above example of H.264 encoding is upgraded to H.265 (HEVC.The earlier FFmpeg class library (about a few months ag

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.

the explanation of the noun in HEVC noun explanation In order to understand the details of the HEVC encoder, it is necessary to have a clear understanding of the following nouns. 1) LCU A coded image is usually divided into a number of basic units that can be set at their own size, called LCU (largist Coding unit). The size of the LCU can be set to a range of 16x16-64x64. 2) Slice The slice is a sequence o

Release date:Updated on: Affected Systems:FFmpeg 2.xDescription:--------------------------------------------------------------------------------Bugtraq id: 65011 FFmpeg is a free software that allows you to perform video, transfer, and stream functions in multiple formats of audio and video. An error occurs in the "hls_slice_header ()" function (libavcodec/hevc. c) of FFmpeg 2.1, which can lead to NULL pointer reference. Gynvael ColdwindLink: http

Recently started to do HEVC, wherein the entropy decoding as the lowest part, because and H264 almost, the difficulty coefficient is not very big, mainly is some check table operationThe specific implementation principle is not detailed, mainly from the code to explainFirst of all, the entropy decoding part of HM Engineering is analyzed as the guide, because it will be run on DSP and then rewritten as C code, and the process is stronger.Code AnalysisF

Note: The HM code version is hm-16.2+scm-3.0rc1/.three ways to scanHEVC has three scanning methods: Diagonal scan, horizontal scan, vertical scan in the upper right corner. Corresponds as shown.Figure 1 HEVC three ways to scanDepending on the mode, use one of the three ways: horizontal, vertical, diagonal. For blocks that exceed 4x4, the blocks are first divided into several 4x4 CG (coefficient Group), and CG and each CG interior are scanned using the

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

Color drift occurs if the chroma signal uses a larger quantization step. To address this problem, the HEVC standard limits the quantization parameters of the chroma signal to 0~45. In particular, the luminance signal QP is less than 30 o'clock, the chroma signal QP is the same as the former, and when the luminance signal QP is 30~51, the corresponding relationship is shown in the table below.------------------------------------------------------------

In the hevc/h265 code, there are three used namespace:1. DF2. DF::p Rogram_options_lite3. rasteraddressFor the first DF namespace, I have been baffled, what does DF mean? The foreigner to the name is very important, there must be a reason. hevc/h265 code is written by: Vidyo, Toshiba, Ti, Ten, Technicolor,suehring, Sony_uk,sony, Skku, Sharp, Samsung,rim, Qualcomm, Pansonic, Orange,nokia,nec,motorola,mitsubi

Yesterday tried to edit the blog post with Markdown, the result of the HTML file generated by the Import blog editor failed, is really depressed. Temporarily do not struggle with what to edit the blog, or to quickly look at the HEVC inter-frame prediction mode bar. Now I want to know what the prediction pattern is for each CU, so the first thing is to see how the code stores the information. Yesterday, I have listed the functions called by all the pat

There is a field in the action that is of the birthday or date type. When we pass the value, it must be written as to automatically convert the type, however, in some cases, you may need to write 19990101 so that automatic type conversion is not performed by default. In this way, you can write a custom type converter to achieve conversion. Struts2 has two types of converters: Partial: it applies to an action conversion type. First, you need to customi

default values), and it is much easier to modify the configuration file for multiple parameters. Therefore, we recommend that you use the previous method for setting. After the preceding configuration, the encoder can encode your specified YUV test file as a binary code stream file. Besides, the decoder is used. It is exactly the same as the encoder before "command arguments" is entered. The input command is-B XXX. bin-O deco. YUV,-B specifies the input binary code stream, that is, the encodi
