I guess I’ve got all necessary functions from DirectShow for PPCam project, and created a DirectShow binding. It is still partial as I didn’t check other APIs that are unrelated to PPCam project.<\/p>\n
I keyed ~1,800 lines of codes today (include blank and comment lines), what I did is reading MSDN, dig out what kind of APIs I need to use, then check Windows SDK to get the C version of declaration, and write binding. There is a great sample<\/a> from adapower.org, which taught me how to make it.<\/p>\n Actually this is a nice exercise, using Ada doing DirectShow stuffs is actually using C interface. DirectShow is purely COM based so using OO language, especially C++ is the most natual way, but, I still believe using C is the best way to understand what’s inside, and this helps me know more about the whole structure, and do help implementing good programs.<\/p>\n","protected":false},"excerpt":{"rendered":" I guess I’ve got all necessary functions from DirectShow for PPCam project, and created a DirectShow binding.
