音频技术源代码

一个优秀的音频播放器的源代码，欢迎大家和我讨论-an outstanding audio broadcast of the source code, we welcome the discussion and I

mpeg4的解码器。核心采用xvid的解码库，提供好了所有的外部接口。是一个十分简单的样例。-mpeg4 codec. Using the core xvid codec library, providing better all the external interface. It is a very simple example.

本程序设计为人与人对弈，双方有一方五子连成一线即为赢。 设计一游戏变量（3到9之间），用来控制显示面板的大小，即用户可选择生成3×3到9×9的棋盘。

一个能创建AVI文件的类(4KB)-can create an AVI file type (4KB)

hik mp4文件播放源代码，更新：1、增加抓图函数Hik_PlayM4_GetBMP（）和Hik_PlayM4_GetJPEG（）用于修正在 暂停状态下无法抓图的bug；这两个函数在播放时可以随时调用。 2、增加是否跳帧函数，在帧号不连续时是否跳下一个I 帧播放，默认情况下是跳下一 个I 帧播放。 3、增加解码回调函数Hik_PlayM4_SetDecCallBackMend(), 和以前解码回调函数区别 在于增加了用户传递参数。-hik mp4 file player source code, update: 1, increase capture function Hik_PlayM4_GetBMP () and Hik_PlayM4_GetJPEG () for an amendment to suspend the state can not capture the bug these two functions in the playback can be used any time. 2, whether the increase in frame-skipping function, in the frame No. discontinuous jump when a I-frame playback, default is a jump off I-frame playback. 3, an increase decoding callback function Hik_PlayM4_SetDecCallBackMend (), and the callback function before decoding difference is an increase of the user transmission parameters.
