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 e
15 EncoderAn encoder is a hive used by ffmpeg to encode a multimedia stream.All built-in encoders are supported by default when compiling build FFmpeg. You can manually set --enable-lib options to support external (extended) libraries. You can take advantage --list-encoders of all possible encoders in the configuration optionsYou can use --disable-encoders Disable all encoders, or individually --enable-encoder
My blog tells about WMS9, can implement streaming media server, but without WME (Windows Media Encoder) support, always feel the lack of something, Here's how to get the device video audio stream through the. NET implementation WME and push it to remote (of course, local) streaming media broadcast publishing point.
First, download the WME9 SDK, installation completed: This step is to experience the main WME can achieve those functions.

the generation of self-encoder against network Aegan
1 Introduction
Autoencoder is a good special functions extraction model, however, if we use Autoencoder's decoder part as a generator, the effect is not good, the main reason is that we extract the H itself is a heuristic feature, without any explicit meaning, So when we use decoder to do generation, we can't give a meaningful distribution of H.Gan is the most good generation model, there is also
Noise Reduction Automatic encoder (denoising Autoencoder) Origin: PCA, feature extraction ....With some strange high-dimensional data appearing, comparison, voice, and traditional statistics-machine learning methods have encountered unprecedented challenges.Data dimensions are too high, data is monotonous, noise is widely distributed, and the traditional method of "numerical games" is difficult to work. Data mining? No useful things have been dug out.
What is a self-encoder?
The self-Encoder itself is a BP neural network. It is an unsupervised learning algorithm.
We all know that neural networks can approach any function with any precision. Here we make the neural network's target value equal to the output value.X, That is, to simulate a constant function:
It's boring, right? What does the network mean when the input is equal to the output? However, whe
Introduction to the SDI encoder (E500)SDI encoder (E500) is a high-performance SDI coding product produced by Shanghai Visual Technology. The SDI encoder is a fully independent research and development of Shanghai Vision Electronics, and is suitable for the coding acquisition and network transmission of all kinds of SDI signal hardware equipment. Compatible with

8-3 encoder with priority in each node
Principle:
In a digital system, several parts may send service requests at the same time, but at the same time, only one of them can send a permitted operation signal. Therefore, you must set priorities for the operation permitted by these control objects, that is, the priority level.
The encoder has 8 inputs and 3 outputs. There is also an input enable EI, output ena
So far, supervised learning of neural networks has been described, that is, learning samples are labeled. Now let's assume we have a training set without tags, where. an automatic encoder is a neural network that uses reverse propagation for unsupervised learning. The purpose of learning is to make the output value equal to the input value. the following is an automatic Encoder:
The automatic

These two days in the attention model, looked at the next several answers, many people have recommended an article neural machine translation by jointly learning to Align and Translate I looked down, The feeling is very good, inside also probably elaborated the Encoder-decoder (coding) model concept, as well as the traditional RNN realization. Then also elaborated own attention model. I looked at it and made some excerpts of it, and wrote it in the fo
Tell us today about the crash when Adobe Media Encoder cc 2015 starts,Let's look at the phenomenon first. That's it,Then I found a lot of ways on the Internet, some methods are outdated, or because now the new version of Adobe Media Encoder CC 2015 has not supported the online methods. Here are some of the methods I've found, and the way I've solved the problem myself, to share with you.Let's take a look at

Optional. Specifies that the ' input ' is overwritten by the output file. This option destroys your original input
bit string. If n=4,k=1, then: (1) turn n into binary that is 100, remove the back 1 bits to 10, plus 1 becomes 11 (2) 11 of the bit number is 2, so need to precede (2-1) 0. becomes 011 (3) to make up the removed bits, that is, 0110.Arithmetic Coding steps: (1) set the current interval [l,h] to [0,1] at the beginning (2) for each event, the encoder is processed according to steps a and B: a) The encoder div
This article introduces a simple Video Encoder Based on FFMPEG. The YUV420P pixel data is encoded as H.264 compressed data. The code of the encoder is very simple, but every line of code is very important. It is suitable for a good study. After the code is clarified, the encoding process of FFMPEG is basically clarified. At present, although I have already completed the program, I still haven't fully unders

MP3 sound quality close to kbps, and the bandwidth of KB can meet the listening needs of 8-bit listeners for 64 Kbps WMA. If you have 10 Mbps of bandwidth and provide 40 kbps of stereo broadcast, enough to build a small digital radio station. An Internet IP address is also involved. If the PC you use to establish a radio station does not have an independent Internet IP address, it cannot broadcast the whole Internet. For more information about how Intranet radio stations can broadcast to the In
