Displaying video with ffdshow MP4

[TouEnMasm]

I search source codes on the subject(asm or c++).
Internet seems to be very poor on this.
I know a few on graphedit and a few on those interfaces (strmif.h):
IFilterGraph,IGraphBuilder,IBaseFilter....

You can consider it as just another DirectShow filter, and so any tutorial for using filters in DirectShow should be adequate.

This one looks fine: http://laganiere.name/directshowTut/

I know this one,he is a perfect code to do what i want.
He play avi and MP3 has others.
The game is to add the ffdshow filters i have tried:

.data
CLSID_video_ffdshow GUID <04FE9017h,0F873H,410Eh,<87H,1EH,0ABH,91H,66H,1AH,4EH,0F7H>>
IID_IBaseFilter GUID <056A86895H,0AD4H,011CEH,<0B0H,03AH,0H,020H,0AFH,0BH,0A7H,070H>>
.code
invoke CoCreateInstance,addr CLSID_FilterGraph, NULL,CLSCTX_INPROC_SERVER,addr IID_IFilterGraph,addr ppvIFilterGraph ;ppv out
;eax S_OK réussite
.if ppvIFilterGraph == 0 ;failed
invoke MessageBox,NULL,TXT("IFilterGraph"),addr comfailed,MB_OK
jmp FindeGraph
.endif
invoke CoCreateInstance,addr CLSID_video_ffdshow, NULL,CLSCTX_INPROC_SERVER,\
addr IID_IBaseFilter,addr ppvIBaseFilter ;ppv out

IFilterGraph AddFilter,ppvIBaseFilter,NULL


all this work but haven't effect.
How add a filter,seem to be the question ?.

The more usable for test seem to be this one,very short:

Use the one with directshow

TOUTENMASM (Yves),
I had a book on DirectShow that I used to write some code a number of years ago. I found it VERY difficult, especially the part about how use a DirectShow filter from within a regular COM program. They are so complicated,...and, there is no function that will validate a DirectShow filter.
I had a bunch of C++ source code that I had downloaded from Cakewalk. They sell audio editing software, and several years ago they were trying to promote a DirectShow Audio Filter as a standard to be used in audio software.
As you have already found, you can learn alot just by playing around with the FilterGraph.
You might find this interesting: DirectShow Samples.

Thanks at all,
The sample sdk cutscene give the soluce.
Here the translate in asm.
he could play mp4,AVI and surely other format.
Can be stop by esc,space or return key.
View is full screen,he need a file as parameter to work.
Some modifies have been made in the headers,download

TOUTENMASM (Yves),
You may also find this interesting: Media Player Classic. It's been around forever, and is Open Source (written in C++).
Source Code repository: Media Player Classic Source Code
As I recall, it used to have the capability to load a DirectShow Filter,...and, has the source code for a number of filters here: Filters

[TouEnMasm]

Here is he soluce To create an instance of a filter,translate from mapper
He give this sort of liste

TOUTENMASM (Yves),
I'm amazed, really,...you are one of the few MASM assembly programmers (besides EDGAR and JAPHETH) that has conquered COM. 
...And, you've done so in spectacular fashion,...(I wish I knew how to say this in French).
