[Other] 一种分级检索MPEG视频的方法 DL : 0: 提出了一种基于样本的分级检索 MPEG 视频的新方法:首先用I 帧的dct_dc_size 字段快速粗检,然后用断层摄影(tomography)法分析B 帧运动矢量的时空分布特性以进一步缩小结果集,最后用DC 图像的精确匹配方法验证检索结果.试验结果表明,本方法所需计算量较小,且可保证较高的检索精度.-presents a sample classification based on MPEG video retrieval of the new method : First of all I frame with the rapid field dct_dc_size rough Frederick, and then use tomography (tomography) Analysis of B pictures motion vector space-time distribution to further narrow the results set, and DC Images precision Matching test results retrieval. test results showed that the calculation method for small and can guarantee higher retrieval accuracy.

[Streaming Mpeg4] h.263编解码范例 DL : 0: h.263的编解码程序。不过编码时只能编码I帧和P帧。解码时在Debug环境下会报错，在Release环境下能通过解码，但是以最快速度播放的。希望大家多多交流，对程序进行一下修改！-the H.263 codec procedures. But only when the coding frame coding I and P frames. Decoding the Debug environment will generate errors in the Release environment through the decoder, but with the fastest speed of the players. We want more, the procedures for amending what!
