h 265 encoder

FFmpeg is a very powerful set of video audio processing libraries, however, the powerful features are generally unavoidable complex implementations, or more realistically, the "trouble" of the deployment and use of the processAbout "ffmpeg How to deploy" this is put in another article, the following into the topic:Both the Encoding encoder module and the decoding decoder module have init initialization method and resource free methodThe Init initializ

encoderIn the metal framework, 3D Graphics rendering commands, calculation commands, and blitting commands must be encoded appropriately before they are committed to a specific device GPU, so that they can be recognized and executed by the GPU.The metal framework provides an encoder protocol for each of the commands:Mtlrendercommandencoder protocol: Provides an interface to encode a 3D graphics rendering command to be performed during a single cycle

together with the application code during compilation, and then loaded to the GPU for execution at runtime. It also supports editing the Metal ing language code at runtime. Metal architecture includes the following important classes or protocols: 1. MTLDevice protocol and Object An MTLDevice represents a GPU device that executes commands. The MTLDevice Protocol defines related interfaces for it, including interfaces for querying device capability attributes and creating specific objects of othe

Tenth chapter, Chapter 11th prefaceFor the network, the data is just the raw byte sequence, but our program organizes these bytes in a way that we can understand, and we generally call this information "information", Convert the information into bytes or replace the bytes in the network with the information we can read these are among the most common tasks in our network transmission, and you may need to work in a standard format or protocol, such as an FTP protocol or a Telnet protocol, or a pr

The Mtlrendercommandencoder object is used to represent the rendering State and drawing commands of a graphical rendering process.Mtl

proved that it can improve the efficiency. Compared with fread each time, fwrite 1 byte without buffering, while making the code clear. We have not tried algorithm optimization yet. For example, during the current decoding, an unsigend int is converted into a corresponding bit, and the most stupid dynamic computation is used. You can consider table-based optimization. However, the current speed is much faster than python. Run on my 1 GB memory virtual machine, Compress and decompr

9. Common models or methods of deep learning 9.1 autoencoder automatic Encoder One of the simplest ways of deep learning is to use the features of artificial neural networks. Artificial Neural Networks (ANN) itself are hierarchical systems. If a neural network is given, let's assume that the output is the same as the input, and then train and adjust its parameters to get the weight in each layer. Naturally, we get several different representations of

SQL Character Segmentation: SQL Character Segmentation For oracle, character string splitting is often encountered during string processing. Unfortunately, the SQL statement does not contain the split function. This is quite confusing for us to write SQL statements. In this case, the string is separated. For example, for a piece of data in the field '1970-mm-265 '; I want to get the mm in it. For other languages, such as awk. Split ("120-mm-

For Oracle, when dealing with strings, there are often problems with string segmentation, but there is no split function in SQL, which is quite disturbing for us to write SQL. In this case, I would say that this string is split.For example, in the field str, a data is ' 120-mm-265 '; If it is between other languages, for example, awk. Split ("120-mm-265", A, "-");p rint a[2]; it's done.1. You may find it ve

version of the self attention mentioned in the paper assumes that the current word is only associated with the R words, so attention only occurs between the 2r+1 words. This will also capture the local information of the sequence (which is actually the convolution window in the convolution kernel) TransformerIn this paper, transformer completely abandons the recursive structure, relies on the attention mechanism, and digs the relationship between input and output, which makes the computati

Log4rs is a highly configurable log library implemented by rust, which is configured in a flexible and relatively rich way to meet most of the project needs. GitHub Address: Https://github.com/sfackler/log4rs. Usage examples Let's first give a simple example, and you can see from this example that log4rs is very flexible to log configuration: #[macro_use] extern crate log; extern crate log4rs; fn Main () { log4rs::init_file ("Config/log4rs.yaml", Default::d efault ()). Unwrap (); For i
