other common modules. The system's media file splitter has a separate splitter module. Therefore, libavformat sub-directories are not required. Libavcodec and libavutil keep subdirectories in the FFMPEG directory.
The libmad project is used for MP3 file decoding. This project contains two functional modules. One is responsible for parsing the MP3 file format, including mpeg1 audio files (MP1, MP2, MP3, and MPa ), read the audio data of each frame. T
For Android package resources, there are assets during project development, but it is said that they cannot be written.
If you want to break the files that need to be used into the APK file, such as the SQLite dB file, the current method is to first store the file in assets in the project, and then when the program is started for the first time, copy the files in assets to/data.
Note that if you directly use dB as the file suffix, the following occurs when you copy a file larger than 1 MB:

decode MP3 files. This project contains two functional modules. One is responsible for parsing the MP3 file format, including mpeg1 audio files.(MP1, MP2, MP3, MPa), reads each frame of audio data; the other is responsible for decoding mpeg1 audio data, and the decoding code is in the libmad subdirectory.
Libmad is an open-source high-precision mpeg1 audio decoding library that supports MPEG-1 (layer I, layer II and layeriii, that isMP3 ). Libmad pro

Features: cheapThe main advantage of this controller is that it is cheap, and the price of the tablet with this controller can be very low, in addition, this product has flash hard decoding (that is, videos embedded in Flash such as Youku and Tudou can be hard solved, so they can be viewed smoothly on the webpage). AML also has many years of experience in set-top boxes, although it is the same as the decoding of the 1080p specification, this solution has better compatibility, so the price sh
The transcoding function was added to the video forwarding program yesterday: the input (Stream/file) is transcoded into the video stream and audio stream in the specified format.
After research, we found that the vlc comes with the transcoding function, but the parameter settings are troublesome.
Our specific requirements are:
Input: rtsp stream or udp multicast data (there is no difference in setting transcoding parameters)
Output: H264 video (644 k) + mp

In this case, we can use the afconvert command. The basic syntax is as follows:
Use-d to specify the frequency format

The following formats can be specified for. WAV files:
UI8 LEI16 LEI24 LEI32 LEF32
For example,-d LEI16 @ 22050 represents 16-bit 22050Hz.
Although today's hard drive is usually dozens of GB, once you store MP3, VCD, and other audio and video materials in your computer, you will feel that the hard drive is always insufficient. There is a great "friend" who can help us, that is, realproducer. You can listen to music, tap your mouse, and instantly convert large audio and video files into small rm files, while the loss of image and sound quality is very small. It can convert media files in Avi, mov, QT, WAV, AU, mpg, MPEG, MPa,
