AAC (Advanced Audio Coding), Chinese name: PremiumAudio encoding, appeared in 1997, based onMPEG-2Audio encoding technology. By Fraunhofer IIS,Dolby Labs,At,Sonyand other companies to develop together to replaceMP3format. 2000,MPEG-4after the advent of the standard, AAC re-integrates its features, adding SBR technology and PS technology, in order to differentiate it from the traditional MPEG-2
This article describes one of the simplest audio encoders based on FFmpeg. The encoder realizes the PCM audio sample data encoded as AAC compressed encoded data. The encoder code is very simple, but each line of code is very important. By looking at the source code of this

What is a video encoder?
Video encoders, also known as video servers, enable an existing analog CCTV video surveillance system to be integrated with a network video system. video encoders play a significant role in installations where your analog cameras are to be maintained.

me two days to get stuck, it makes me feel cold and cool ......
At the beginning, the encoder I designed only needs to pass a surfaceview object and use this object to preview the recorded video. The Code is as follows:
Public class hsf-encoder implements surfaceholder. callback {surfaceholder holder; Public hsf-encoder

FLAC file is a lossless audio compression format, which is the abbreviation of free Lossless Audio codec, which is characterized by lossless compression. Unlike other lossy compression codes such as MP3 and AAC, it does not destroy any original audio information, so it can restore the sound quality of music discs.
Simply put, why do you need to encode? For example, our computer needs to represent letters ' a ', ' B ', and so on, but how are these letters represented in the computer's memory? It is well known that in computer memory data is represented in binary notation, so we need to convert these letters and numbers or symbols that need to be represented into binary representations that can be represented on the co

Hi, this may be a mental retardation, but when I use bbmeg1.24beta17 encoding, I always encounter this underflow problem. The only revelation I get from the log file is that I should change the MUX rate... However, the help documentation says that setting the MUX rate to 0 can force the value to be calculated by the encoder. Does anyone know what v

The S-terminal and YUV components are only a connection interface (not a basis for quality determination). As for the video quality, it depends entirely on the video transfer rate, it is not that the S-terminal must be a low-quality 350 wire, but the YUV is a 425 wire, which is a conceptual error.Q: The broadcast-level cameras have 50 thousand million yuan and up
