mciavi: MCI_OPEN @NNNN should use an open AVIFile/Stream handle. (try 2)

[Joerg-Cyril.Hoehle at t-systems.com]

Hi,

MSDN documents this @NNNNNN case for MCIAVI.

The file name @11223344 encodes an AVIFile handle in decimal notation
in Win3.1 and w2k/NT, but this feature is absent in win95 (KB140750).

Confirming the exception, Wine is currently bug compatible :-) with win95 which will
open a file named "@1024", while w2k crashes at address #x00004000.

open @1024 type avivideo alias a

I verified that w2k's MCIAVI can indeed play a file opened by AVIFileOpen().
    err = AVIFileOpen(&pfile, "test.avi", OF_READ, NULL);
    ok(!err || err == AVIERR_FILEOPEN, "AVIFileOpen error %x\n", err);
    if(!err) trace("AVIFile handle %ld\n", (DWORD_PTR) pfile);

Regards,
 Jörg Höhle
