Thank the great God to share, although now still do not understand, keep everyone together to seePS: A lot of people don't know how to read "FFmpeg". It reads "EF EF em Peg"0. Background knowledgeThis chapter focuses on where ffmpeg are used (here are just a few of the many I know, in fact much more than this). To illustrate: FFmpeg is very important.Use FFmpeg as the kernel video player:
Mplayer,ffplay, shooter player, Storm av, kmplayer,qq av ...
Use FFmpeg as the DirectShow Filt
In the CSDN on this 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

Adaptive Transform acoustic Coding(ATRAC) Is a family of proprietary audio compression algorithms developed by Sony. minidisc was the first required cial product to in1_ate ATRAC in 1992. ATRAC allowed a relatively small disc like minidisc to have the same running time as CD while storing Audio Information with minimal loss in perceptible quality. today ATRAC is used in your Sony-branded

and easy to process in real time.2. 1.1.2 what is G.711 encoding?A:G.711 suggests a typical compression codec method using PCM waveform encoding to achieve higher speech quality, but the data compression rate is low.G.711 it is recommended to describe the μ-law (A-Law) compression of PCM, as shown in:The sampling rate is 8 kHz, and the 12-bit linear A/D is transformed into A digital signal. After the logarithm PCM, the data is compressed to 8 bit, an
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
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

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
before recording the codec of your own learning audio, let's add a bit of hardware knowledgeA series of processors from the 8086 instruction set, known as the x86 processor, 8086 is the oldest 16-bit x86 processor, so the software is labeled I386, indicating that the software is 32-bit, based on the x86 processor , all 32-bit and 64-bit x86 processors can be run (unless the software is marked with a minimum
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
G.723.1 specifies a coded representation that can be used for compressing the speech or other audio signal component of multimedia services at a very low bit rate. in the design of this coder, the principal application considered was very low bit rate Visual Telephony as part of the overall H.324 family of standards.
G.723.1 has two bit rates associated with it. these are 5.3 and 6.3 kbit/s. the higher bit rate has greater quality. the lower bit rate
Audio codec and real-combat article (1) PCM go to AAC (AAC encoding)Author: Liu · Poechant Blog: blog.csdn.net/poechant e-mail: zhongchao.ustc@gmail.com Date: April 7th, 2012
This uses FAAC to implement AAC encoding. 1 Download and install FAAC
The installation process here is implemented on MAC and Linux, and windows can be similar to the reference.
