Codec State

[Alaa Masoud]

Hello All,

I have a problem setting codec state.
I called IAMVfwCompressDialogs::ShowDialog(), then i set
custome config, then clicked Ok. After that, I called
IAMVfwCompressDialogs::GetState(pv, &cb) twice, the first
to know the required size and the second to actually get
the state. After that i saved the *pv to a file. Now when
i get codec state from the file, i called
IAMVfwCompressDialogs::SetState(pv, cb) but when I showed
the dialog, the settings weren't as i saved them in my
file!! I tried this on Microsoft Video 1 & DivX 5.0.2
codecs. Same results

I tried ICSetState, the function failed!

If someone has done this before, plz tell me what did u do.

Thanks in advance.

Alaa,

This has been discussed before, see if any of the earlier threads helps you
(in the end, all point out that SetState() does not work but
SendDriverMessage() does):
