H264封装成AVI文件，帧率问题
从视频监控设备收到标准的264编码数据，以AVIFile API封装成.avi文件。
保存后，用暴风或其它播放器打开，视频数据不连续，几秒跳一帧（视频是没问题的，实时看是正常的）
AVIFile部分的代码如下，哪位大侠给说说。

[解决办法]
你调用这几个的顺序是什么？？我觉得是调用出了问题了。
[解决办法]
open和close只调用了一次吗
[解决办法]
mark
[解决办法]
几个建议：
1. 没有音频流的话就把音频流的设置去掉试试；
2. 如果是固定码率的，试着设置一下这个值：bmpInfoHdr.biSizeImage = 每帧字节数;
3. 我之前用的办法比较笨，因为是变码率的，所以在每次AVIStreamWrite前调用了一次AVIStreamSetFormat重新设置biSizeImage；
