1.环境, DirectX 9.0, , VC 6.0, 或者后来的windows sdk
2.基本概念
3. 不能编译问题, 某些版本不能MFC
Filter Graph:
Source Filters、Transform Filters和Rendering Filters
user defined filter
VC6+ Directshow的com不能在vista上使用,原因com注册失败. 在XP上成功
.(错,vista,UNC机制) -> import 编译不成功.
Contract filter:
1) load graph
2) why cannot compile, a) extern ? b) compare with windows sdk?
2010-3-12,采用 Render Filter, 运动播放成功。时钟调节。 使用了static lib,不能用vc7编译。 这是vc7.0, vc6.0 static lib兼容性不好的缘故。
声音render,视频render不再同一个线程,故video render sleep 后,声音未停。
我们一般戴的手表、手机、电脑里的时钟,误差在5ppm以内,一般能做到年误差30s。
1ppm的误差意味着每天误差0.09s,一年31.5s

Design
1. how to communate
server: Very 1 minute (24*60 samples) UDP broadcast
client: send sample count, time to server in every 10 seconds
2. how to adjust time.
pDest->SetTime(&TimeStart, &TimeEnd);
3. Edge process.边缘融合法
color a+ color a =linial relationship?
By this weekend:
1. DS filter, syn, image process
- direct to boost?
