The project uses video codec, which has been around for the last half a month. To be honest, it has taken a lot of detours and wasted a lot of time. Record your final results here, hoping to help others.

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

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

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.
