PDU codec details
Brief Introduction
SMS is a specification developed by ETSI (GSM 03.40 and GSM 03.38 ). It can send up to 160 characters, when using 7-bits encoding. 8-bit encoding (up to 140 characters) is usually not displayed directly through the mobile phone; it is usually used as a data message, such as pictures and ringtones in smart messaging) and ota wap settings. 16-bit information (up to 70 characters) is used to display Unicode (ucs2) tex

Video and Audio Encoding/decoding technology:
(1) silent FLC
(2) audio and visual Avi
(3) Both capacity and quality MPEG
The quality of MJPEG encoding is quite high. It is a kind of encoding with the highest quality requirement. It is a non-linear system.
Therefore, it tries its best to use the jitter algorithm during the Encoding Process (you can also set it to not shake) to simulate the effect of the true color. This algorithm is alm
To process images in eclipse, You need to introduce two packages:Import com.sun.image.codec.jpeg. Unzip codec;Import com.sun.image.codec.jpeg. encode imageencoder;Error:Access restriction: the type specified imageencoder is not accessible due to restriction on required library C: \ Java \ jre1.6.0 _ 07 \ Lib \ RT. Jar
Solution:By default, eclipse sets these access-restricted APIs as error. You only need to select forbidden references (access rules) i
UnicodeDecodeError: 'ascii 'codec can't decode byte 0xe5 in position 0: ordinal not in range (128), ordinalposition
Python encoding has always been a headache. For example, matplotlib only accepts UTF-8 encoding for plotting. If it is not set, an error will be reported during plotting. Have time to complete this python code;
As shown in the title, solution: add
Import sysreload (sys) sys. setdefaultencoding ("UTF-8 ")

In CentOS, the "UnicodeDecodeError: 'ascii 'codec" problem occurs in yum.Problem
When CentOS 6.5 is installed, the following error occurs when you plan to use the yum Installer:

NDK Version Number requirementsNDKR7 or update, I tested it on the ndkr9b.2. Builder Configuration MethodFirst, in the Builders folder, click New and create a new builder.Then, choose the builder that created the program type.Finally, at the location.

Both Python2 and Python3 were installed under Windows, but the following error occurred while using the command to update the PIP:Workaround: Modify the mimetypes.py file, the path is located under the Python installation path under the lib\mimetypes.py file. Add the following lines under import to set the encoding to ' GBK ':1 if ' GBK ' 23 sys.setdefaultencoding ('gbk')Successfully resolved, Fix unicodedecodeerror: ' ASCII ' codec can ' t decode b
3G video file 3GP codec Library
Parse the 3GP file. parse the frame and related information, such as keyframe.
Based on the parsed data, you can cut the file according to the original keyframe or the file size.
The library contains the splitter and MUX operations on the 3GP file. this frees your company from great pains in the study of the 3GP file, and wins time for the release of your company's products. you can also customize it as needed.
OS:
Since the last time the system was reinstalled, the driver of the sigmatel high definition audio codec device was not installed. It has been plagued for several months. To watch movies and listen to music, you must switch to Linux, fortunately, this problem was finally solved today and I wrote it to myself:
If the driver was not installed in the past, I went online to find a method. The solutions provided by enthusiastic netizens were the same: "Inst
Amr generally refers to AMR-Nb, which is 8 KHz sampling and has 8 bit rate encoding/decoding methods.Algorithm. In addition, there are nine bit rate encoding algorithms for AMR-WB, namely 16 KHz sampling. Because the AMR-WB sampling rate is high, the complexity is about twice that of AMR. Both AMR and Amr-WB belong to the speech codec, which does not work well in Audio Encoding. To improve the audio encoding performance, Amr-WB + appears. Amr-WB + sup
1. Image compression is divided into lossy compression and lossless compression: Lossless compression is not to destroy the image information, or all the image information can be restored by a certain algorithm compression, lossless compression can not reduce the memory footprint of the image, if you want to reduce the image consumption of memory capacity, it is necessary to use lossy compression. lossy compression2. Common image format:1)2) GIF is a graphic Interchange Format (Graphics Intercha
1. What is JSON serialization and binary serializationUsually we use JSON as a transmission in the program, and JSON is serialized as JSON. and binary serialization is usually when we convert the data to binary for transmission, and then we do all kinds of conversion operations2. Applicable scenariosSmall series think that when the data using JSON transmission, the application and the Web and control layer conversion, front-end JS to the JSON support is good, and the program internal system and
Vs2013 Create python file, in the file is not entered in Chinese, encoded as utf-8 ,Then, after entering a few lines of Chinese, again with notepad++ to see its code as follows, in vs Run also error (run with cmd will not):Based on the experience, this is the problem of character encoding, try to convert the python file into utf-8 , directly on the notepad++ turn utf-8 no BOM encoded format, save, open vs, there will be the following tipsDo not choose No , or you may be prompted with the follow
[Python] UnicodeEncodeError: 'gbk' codec can't encode character solution,
Compiling a python script in windows causes serious Encoding Problems.
When writing network data streams to files, we will encounter several encodings:
1: # encoding = 'xxx' here (that is, the first line of the python file) encoding refers to the encoding of the python script file itself, irrelevant. As long as XXX is the same as the file encoding. For example, you can set va
