yah - we need to create a vfw32.inc and vfw32.lib that get functions from avicap32.dll, avifil32.dll, and msvfw32.dll
not from vfw32.dll, which does not exist
vfw32 is, however, the correct name for the include and import library
at least, that is how MS C handles it
i suppose we could put the functions in 3 seperate INC/LIB pairs

vfw32.inc/lib in masm32 version 10 do not have the MCIWndCreate(A/W) functions
vfw32.inc/lib in masm32 version 11 do have the MCIWndCreate(A/W) functions, but try to import from the nonexistant DLL
i suppose this should be a bug report in the MASM32 project subforum   :P

I'm sure I posted an import library and an incomplete include file (for everything but the procedure prototypes, which are in separate include file that AFAIK is complete) somewhere here, but I can't seem to find it now, so here they are again.

How make player? I try hook mciSendCommand

[dedndave]

ok - my next question is...
how do we emulate all these macros ?   :P

i guess someone with a C compiler can do it 

[dedndave]

maybe this guy has already done so
it looks like many of the macros are covered in ASM source...

http://4coder.org/assembler-source-code/73/

you can download the entire package, or modify the URL as follows for an example...

http://4coder.org/assembler-source-code/73/libmci/MCIWndCanConfig.asm.html

ok - well, it's not perfect
that particular function is supposed to be a macro, not a proc
but, the code is there to figure out how to write the macro

When I change my simple multimedia example so that it can list all file types it plays anything I throw at it. The example link below includes the player and a small AVI, WMV, WAV, MP3 and MPG-1 sample media file. At least on my Windows 7 64 bit machine and my old XP Home Edition SP3 machine it plays them all perfectly. Using my example my Win 7 machine will also play MPG-2's but my XP machine will not.

i am running XP MCE2005 SP3
it plays the movie clip fine, Bill   :U
all you need is an MPEG-2 codec

here is one i know works...

i use the k-lite mega codec package, which has all kinds of stuff   :P

[Bill Cravener]

Hi Dave, yes I figured that was the case. I need to spend some time on my XP box and get everything up to date. It really gets ignored now that I have this new Win 7 box. :bg

[dedndave]

well - MCE won't work without an MPEG-2 codec
oddly enough, MS does not provide one - lol
for that reason, MCE was only available in OEM machines, and had to be bundled with some kind of player that provided one
this Sony machine came with WinDVD, which includes the codec
the MPEG-2 codec is also required to play DVD's

Install K-Lite Codec Pack and you Simple MP3 Player may show all video files

http://www.erightsoft.com/SUPER.html - Starnge When I install this converter all video files may show too, including MKV conteiners

[jj2007]

Here is one that takes a file from the commandline and plays it immediately.

I had lots of trouble playing avi files (decompressor not available) until I found a site that said "rename them to mpg", and wow, it worked :dazzled:

[dedndave]

little secret - that also works for VOB files   :P
although - i didn't have any luck with that player - lol

[bomz]

It 's depend from codecs which install and registering in system
