能在linux播放电视，也能利用它来录制自己的视频和音频。对做linux视频采集是一个非常好的参照例子。-in broadcast television can also use it to record their own video and audio. Linux done right Video Capture is a very good example of the light.

在文件stefan.par中输入必要的参数，只需要文件名称。一般需要一个yuv文件。然后就可以进行ipp mepg4 的快速编码，效率很高。另外，你必须安装intel的ipp库-the document stefan.par the necessary input parameters, need only file names. General needs a YUV document. Then you can ipp mepg4 rapid coding, high efficiency. Also, you must install the Intel library ipp

G721-G723　源代码 G.726 is an ITU-T ADPCM speech codec standard covering the transmission of voice at rates of 16, 24, 32, and 40 kbit/s. It was introduced to supersede both G.721, which covered ADPCM at 32 kbit/s, and G.723, which described ADPCM for 24 and 40 kbit/s. G.726 also introduced a new 16 kbit/s rate. The four bit rates associated with G.726 are often referred to by the bit size of a sample, which are 2-bits, 3-bits, 4-bits, and 5-bits respectively.-G721-G723 source code of G.726 is an ITU-T ADPCM speech codec standard covering the transmission of voice at rates of 16, 24, 32, and 40 kbit/s.

运动估计是视频压缩中帧间预测编码的关键技术之一，在各个压缩标准中都广泛使用了基于块的运动估计技术。由于运动估计通常具有较大的运算量，因此对压缩性能具有重要的影响。本文在分析了视频序列的特点和对现有的快速搜索算法深入理解的基础上提出了一种改进的快速运动估计搜索算法，通过实验表明该算法对压缩性能有了较好的改进。 -Video Compression interframe predictive coding one of the key technologies. in various compression standards has made extensive use of block-based motion estimation technology. As the motion estimation is usually larger amount of computation, so the compression performance has a significant influence. Based on the analysis of the video sequence and the characteristics of the existing Quick Search Algorithm in-depth understanding on the basis of a modified Quick search motion estimation algorithm, experiments show that the algorithm has better compression performance improvements.
