Label: Use SP file code BS algorithm nbsp technology c 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

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.

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

[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
