Hi,

I'm struggling with the conversion of WriterAdvanced2.SetInputSetting to
Delphi. I'm using DSPack and the closest I can get is the following:

try
CheckDSError(AsfWriter.WriterAdvanced2.SetInputSetting(
0, g_wszDeinterlaceMode, WMT_TYPE_DWORD,
PByte(WM_DM_DEINTERLACE_NORMAL), SizeOf(PByte)+1));
except
on E:Exception do
begin
ShowMessage( 'Unable to set de-interlace mode - ' + E.Message );
Exit;
end;
end;

CheckDSError raises the exception: One or more arguments are invalid
($80070057).

Without the +1 in the SizeOf(PByte) argument, I get a more general Access
violation error:

"Access violation at address 088877C7 in module WMVCORE.DLL. read of address
00000001"

I've managed to stumble over other hurdles/challenges in the project
(stopping the asfwriter writing a file, setting my own profiles and adding
Stream HeaderInfo) but this one's got me stumped.

I've tried various variable types, tried changing the last argument to
different "SizeOfs" and tried moving the code to before, during and after
the FilterGraph is built without any success.

Any help on this one would be appreciated please. I have asked in the dspack
forum but nothing was forthcoming.

Thanks,
John.
