koi8-r encoded string and wants to convert it to Unicode. The simple approach is to:qbytearray encodedstring = "...";qtextcodec*codec=qtextcodec:: Codecforname ("Koi8-r");QString string = Codec->tounicode (encodedstring);Thereafter, the text string is converted to Unicode. It is also simple to convert a Unicode string into a locally encoded string:QString string = "...";Qtextcodec qtextcodec:: Codecforname

probabilities Visual redundancy: The human visual system is insensitive to certain details Knowledge Redundancy: The structure of regularity can be obtained by a priori knowledge of Beijing knowledge 4. Data compression classificationLossless compression (Lossless) The image is exactly the same after decompression Low compression ratio (2:1~3:1) such as: WINZIP,JPEG-LG lossy compression (Lossy) Image inconsistency after decompression before compressio

JPEG codec is used for compresses original raw image and decompresses original JPEG image. This hardware circuit performs all the functions required for compression/Decompression: discrete cosine transformation, quantization, and Hoffmann encoding. Encoding function: Input raw image: Format: ycbcr4: 2: 2, rgb565 Output JPEG file: Baseline JPEG, Color Space: ycbcr4: 2: 2 or ycbcr4: 2: 0 The progressive mode is not supported. Decoding function: Input

First, the concept The unit of the network transmission is bytes, how to convert the application's data to bytes, and the conversion of bytes to the data of the application, it is necessary to mention the encoder and decoder we introduced in this article. The components that convert the application's data to a network format and the data that transforms the network format into an application are called encoders and decoders, and a single component with both features is called a

After reading the introduction of H264/AVC codec, I just left the following three articles in my mind:1, H264 does not understand how to implement a codec, just a coded video bit stream syntax, and the Bitstream decoding method, this is similar to MPEG.2, H264 and once the standard (such as H261, H263, MPEG-1, MPEG-4) codec implementation process is not much diff

How to compile the Opus audio codec library for AndroidThe Opus audio codec library is the next generation of the Speex audio codec library. It has made great progress in terms of codec performance and quality. Opus compilation is very simple, but the official did not provide a detailed Android version Compilation Guid

header that contains the length of the serialization and its type. Deserialization is based on the header at the time of decompression. If you want to transfer 2 types of data on the socket, stock quotes information and options Market information: A.

period of time, contact with a lot of people in the same industry, especially the use of FFmpeg audio codec, some have many years of experience in the "Great God", some have just started to learn beginners. In the process of discussing with you, I suddenly found a problem: there seems to be an insurmountable gap between the "great God" and the beginner. The "Great God" is highly skilled and explores esoteric issues, while beginners remain at the intr

Media services are the main services of the network. Especially with the rise of mobile Internet businesses, among operators and application developers, media businesses are extremely heavy. The media codec service involves demand analysis, application development, and license release charges. Recently, due to the project relationship, we need to clarify the media codec. What we do is to look at the specifi

As we thought, what should I do if the content of a text cannot be parsed at a time? The answer is to use an object to save these unresolved objects for parsing. This object is generally stored in the session. 1. Text Encoder Package COM. boonya. protocol. codec. self; import Java.

Originally did a very long time audio and video codec things, should do a summary. Here is about the audio and video coding This kind of work gains and losses and trade-offs, in fact, the main is to give up, there is no reason, right when a listen. Let the readers judge for themselves.Take video coding standard H., this is a good thing, after the standardization of video coding, compatibility issues "by laws", conducive to film, video and other dissem

commons-codecis a package provided by the Apache Open source organization for digest operations and encoding. In this package is divided into four types of encryption: Binaryencoders, Digestencoders, Languageencoders, Networkencoders.Today I would like to introduce you how to use commons-codec the package to complete the common coding, digest operations.Base64Example code:@TestpublicvoidtestBase64(){ System.out.println("==============Base64=========

OpenSSL to Base64 codec specification support is poor, using it to encode and decode the results of other languages such as PHP processing is not convenient, notice a few of the following collation1, if the PHP encryption results do base64 encoding length less than 64, you need to add a newline character OpenSSL to decode;2,php needs to insert a newline character for Base64 encoding results every 64 characters, and OpenSSL decodes it. (The reason is t

"unicodeencodeerror: ' ASCII ' codec can ' t encode"Python default environment encoding can be obtained by using the following method:　　The ASCII encoding is essentially the way in which Python naturally calls the ASCII codec to process the character stream, and throws an exception if the character stream is not within the ASCII range (ordinal not in range (128)).The solution is simple, modify the default e

For Java-provided object input and output streams ObjectInputStream and ObjectOutputStream, you can write Java objects directly to the file as a stored byte array, or you can transfer them to the network. For Java developers, the default JDK serialization mechanism avoids manipulating the underlying byte array, which can improve development efficiency.1. Why serialization is requiredNetwork Transmission and serialization of ObjectsWhat the 2.java codec
