结合avi 视频文件头十六进制码分析AVI 格式 这段时间要搞视频合成方面的东西，因此打算先弄明白avi 视频的格式，介绍这方面内容的东西google 一下一大堆，可是很悲剧，现在的人基本上都喜欢copy，内容基本来源于同一篇，对我没什么实质性的帮助。本来是希望通过看看一些 avi 合成的源码来分析avi 的结构的，可是windows 下的程序基本是调用 directshow 完成的，格式方法都封装好了。 百思不得其解之余，还只自己分析吧。 开始之前，先看看 avi 的文件格式图： 下面我们将结合一以下数据进行分析（该数据截取于是某个视频文件的文件头）： [ 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 0123456789012345] 000000000: 52 49 46 46 DC 6C 57 09 41 56 49 20 4C 49 53 54 |RIFF.lW.AVI LIST| 000000016: CC 41 00 00 68 64 72 6C 61 76 69 68 38 00 00 00 |.A..hdrlavih8...|e 000000032: 50 C3 00 00 00 B0 04 00 00 00 00 00 10 00 00 00 |P...............| c 000000048: A8 02 00 00 00 00 00 00 01 00 00 00 00 84 03 00 |................| 000000064: 40 01 00 00 F0 00 00 00 00 00 00 00 00 00 00 00 |@...............| 000000080: 00 00 00 00 00 00 00 00 4C 49 53 54 74 40 00 00 |........LISTt@..| 000000096: 73 74 72 6C 73 74 72 68 38 00 00 00 76 69 64 73 |strlstrh8...vids| 000000112: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| 000000128: 64 00 00 00 D0 07 00 00 00 00 00 00 A8 02 00 00 |d...............| 000000144: 00 84 03 00 10 27 00 00 00 00 00 00 00 00 00 00 |.....'..........| 000000160: 40 01 F0 00 73 74 72 66 28 00 00 00 28 00 00 00 |@...strf(...(...| 000000176: 40 01 00 00 F0 00 00 00 01 00 18 00 00 00 00 00 |@...............| 000000192: 00 84 03 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| 000000208: 00 00 00 00 69 6E 64 78 F8 3F 00 00 04 00 00 00 |....indx.?......| 000000224: 01 00 00 00 30 30 64 62 00 00 00...
