hi...
A have several isue...
First:
xVideo_DVDGetProperty(chan,prop,val)
I can got total duration, but current position do not work...
Please Help file is terrible bad for this function.
(I don't believe that you have double function for same thing for' prop' duration/ position).
This do not work neither in demoDVD.exe
One question, how to change result of measure( secconds, milisec, etc)?

Seccond
xVideo_MIX_StreamCreateFile is NOT in *.h file
So, I can't use them.
If you make that function work, please explain me how to add LPCSTR file to void mstr[0]..
With File_add i have flickering of added file...
It will help if you explain me what that function do... and layer stuff, you haven't any explantation about layers anywhere.

3:
 Can you give mi code i C or C++ how to retrieve decoders and devices from system?
   I can't understand delphi example( Actually I understand, but I must Export every single encoder/decoder/device to GM one by one... I can't see, how to do that from example).
Bass dlll have similar function's and forks fine for me.I need something similar.
  
4: Please write somewhere what work in lite version, and what do NOT.

5: Please, please try to avoid result's in void or HEX... I can't retrieve them well.
 everything else is good ( double, DWORD,string). This is due GM restrictions ( reals and null terminated strings)

6: You haven't function to LOAD bitmap as resource. I can't to do that in GM.
    ( Truth is that I can, but my result is not valid for C or C++),
    So everything related to overload Bitmaps not work for me


And at last.. I was added in example ResourceFree

P.S. If you make function who will return X/Y cords, you can make to return just cords of active window itself Top_X and Top_Y in pixels , since I can find mouse position on desktop in pixels.

  I suggest looking over http://surodev.com/downloads/xVideo1.2.zip update.

The xVideo_MIX_StreamCreateFIle was removed. A easy function was added, so that you can add a new mix channel.

Chan :=xVideo_StreamCreateFile(PChar(file1),0,panel1.Handle,0);
   if chan<>0 then
   begin
    xVideo_ChannelAddFile(chan,Pchar(file2),0);
    xVideo_ChannelAddFile(chan,Pchar(file3),0);
    xVideo_ChannelAddFile(chan,Pchar(file4),0);
  end;
  xVideo_ChannelPlay(chan);

You can add up to 15 new videos to mix to a channel. A HSTREAM mixer will be added soon, so that you can mix and control each stream individual.
Also, i suggest looking over the DVDDemo

[zmmaj]

Ok i will download update...
I hope and xVideo_DVDGetProperty(chan,prop,val) will work as well...

I was download update... DVDDemo are a same... Nothing different... or I miss something
there is no example for xVideo_DVDGetProperty(chan,prop,val) function

[Ionut Cristea]

procedure TFormPlayer.SetTitlesInfo;
var
  titlecount: integer;
  I: Integer;
  item: TmenuItem;
  item2: TmenuItem;
  chapcount: Integer;
  J: Integer;
begin
  PopUpMenu1.Items.Items[3].Clear;
  titlecount:= xVideo_DVDGetProperty(Chan, xVideo_DVDTitles,0);
  if(titlecount<0) then exit;
  for I := 1 to titlecount do
  begin
    item:= Tmenuitem.Create(FormPlayer.popupmenu1);
    item.Caption:='Title '+inttostr(i);
    item.OnClick:=formplayer.PlayTitleClick;
    PopupMenu1.Items.Items[3].Add(item);
        //get the title number of chapters
    chapcount:= xVideo_DVDGetProperty(Chan, xVideo_DVDTitleChapters,i);
    for J := 1 to chapcount do
    begin
     item2:= Tmenuitem.Create(FormPlayer.popupmenu1);
     item2.Caption:='Chapter '+inttostr(J);
     item2.OnClick:=formplayer.PlayChapterClick;
     PopupMenu1.Items.Items[3].Items[i-1].Add(item2);
    end;
  end;
end;

My bad...
I have problem with
xVideo_DVDGetProperty( chan,xVideo_CurrentDVDTitle,xVideo_DVDCurrentTitlePosition);
Is that same as
xVideo_DVDGetProperty( chan,xVideo_DVDCurrentTitlePosition ,0);

from nether I can't got a value.
Function
xVideo_DVDGetProperty( chan,xVideo_CurrentDVDTitle,xVideo_DVDCurrentTitle);
works, and return some value, but I don't know what that value represent ( secconds, miliseconds etc);

As I say help for this function is very messy...

xVideo_ChannelGetPosition(HSTREAM chan,DWORD mode);
DON'T work neither in DVD demo. For that is simple reason.
Every chapter have different length and result chan is one for any chapter.
So this function for DVD with several chapters will always return 0.
I must say this function work well for single  *.vob file.

[Ionut Cristea]

  The position values are always in miliseconds. I will update the CHM.

[zmmaj]

Tnx man, now function
xVideo_DVDGetProperty( chan,xVideo_CurrentDVDTitle,xVideo_DVDCurrentTitlePosition);
works, but result is in seconds as I can see... that is OK for me

but with
Chan :=xVideo_StreamCreateFile(PChar(file1),0,panel1.Handle,0);
   if chan<>0 then
   begin
    xVideo_ChannelAddFile(chan,Pchar(file2),0);
    xVideo_ChannelAddFile(chan,Pchar(file3),0);
    xVideo_ChannelAddFile(chan,Pchar(file4),0);
  end;
  xVideo_ChannelPlay(chan);
I can see only first loaded video...
If I set to windowless I have masive flickering of playing 2 videos...

[Emil Weiss]

oops.. changed

[Ionut Cristea]

but with
Chan :=xVideo_StreamCreateFile(PChar(file1),0,panel1.Handle,0);
   if chan<>0 then
   begin
    xVideo_ChannelAddFile(chan,Pchar(file2),0);
    xVideo_ChannelAddFile(chan,Pchar(file3),0);
    xVideo_ChannelAddFile(chan,Pchar(file4),0);
  end;
  xVideo_ChannelPlay(chan);

This because you don't resize the videos streams. If you don't do that , the videos will be displayed on full video window.
Use something like this:

xVideo_MIXChannelResize(chan,combobox2.ItemIndex,rect1.Left,rect1.top,rect1.Right,rect1.Bottom);

2nd paramaeter is the stream mix index(0-first, 1- 2nd....)

[zmmaj]

tnx, I will try this your way..
 I was try with second way..
AddWindow , and then resize Window.. and I got PIcture in picture with flickering..

YES !!! work without flickering in your way:)
but I must to initialize all with windowLess attribute, But OK...

What else work for sure from MIX stuff?

[Ionut Cristea]

I'm glad that you make it to work. Setting alpha value of a stream will work, resizing also will work

[zmmaj]

hm... since we hear sound from all new added video to channel, I thing we need some function for sound control for each layer. At least to mute/unmute sound from specific layer.

[Ionut Cristea]

  That is not available with xVideo_ChannelAddFile function. What you want can be achieve with the xVideo_STREAM_MIX flag at stream creation.

[zmmaj]

I can't understand how, but OK, maybe in future you will release some C++ example how to do that.

I have pproblem with
GM_xVideo_ChannelSetAttribute(chan,xVideo_ATTRIB_PAN,value)  after settings new value, I got very strange results.
for example 0 is start position (left=rigt), after I do pan+=2, with
GM_xVideo_ChannelSetAttribute(chan,xVideo_ATTRIB_PAN) I got 1000 or -1000 (with pan-=2).

Is this my wrapper error ?
I was double check, all is ok...
Both functions work well with Volume flag.

One more.
I was ask about working MIX functions
You said that will alfa working BUT, you havent xVideo_MIX_ChannelAlpha(HSTREAM chan,int alpha) in *.h file
if you mean on  xVideo_ChannelSetAttribute  that is OK, but this function can't change alpha value of eg. layer 2

[zmmaj]

Can you help me with device enumerations and callback stuff?

Can you make that functions easier?
eg.  GetAudiodevices(device_index); just as is in Bass.dll

This your way is simply to confused.
I can't understand Delphi example code at all...

example..
in almost every delphi example you have next function
 xVideo_ChannelGetConnectedFilters
but that function is NOT in *.chm... I don't know usage of this, or what they work
Especially I don't understand how callback's works.
please one C or C++ example, or,  at least write me what exactly callbacks return as result...
And example how to use arguments of that calls...
Reason is Simple,I cant make to work thry wrapper such calls , so I must make something what will return similar results in main function itself.


I was update wraper for GameMaker...
Now work multimedia, DVD, and Movie Mix...
here it is Link
http://www.host-a.net/u/zmmaj/gmDVD%20ver%201comma1.zip
I was also use MaxWinapi gex extension, you will need them
Link for used Gex extension
http://www.host-a.net/u/zmmaj/maxwinapi2.gex

[zmmaj]

uh.. Nothing about callbacks yet

[Ionut Cristea]

BOOL CALLBACK CallBackFilters(void * Filter, PCHAR FilterName,BOOL pp,void* user)
{
   ///do something with values received
}

.......

xVideo_ChannelGetConnectedFilters(chan,&CallBackFilters,NULL);

I hope this helps.

[zmmaj]

Umgh...
That functions return BOOL, if I am right...
and please give me example for "FilterName", and"Filter". From where I got that names( filter and Filter name)?

I only can to do next in wrapper
xVideo_ChannelGetConnectedFilters(chan,CallBackFilters(void * Filter, PCHAR FilterName,BOOL pp,void* user),NULL);

But this wont work...

[Ionut Cristea]

  What you want to do is not not correct. The second parameter should be the a pointer adress of a callback function. Maybe should i implement a function similar to BASS?   

[zmmaj]

Yesss if they will be like in bass that will be great:)

Make it simple... Return name/id/attributes/etc(index, Video/audio/recording) to get names/index, atributes,capabilities etc... I will make loop outside wrapper..
 I am stuck here
For all calback is same
or give me example of that names... Maybe I understand at last what they are and from where comes...
