et AVI spørgsmål

If you have the Video for Windows Development Kit all the info is
in there, But  apparrently there is a struct at the start of the
.avi file.

Look up MainAVIHeader in the vfwdk help file for more, but here is
the structure -

typedef struct {
        DWORD  dwMicroSecPerFrame;
        DWORD  dwMaxBytesPerSec;
        DWORD  dwPaddingGranularity;
        DWORD  dwFlags;
        DWORD  dwTotalFrames;
        DWORD  dwInitialFrames;
        DWORD  dwStreams;
        DWORD  dwSuggestedBufferSize;
        DWORD  dwWidth;
        DWORD  dwHeight;
        DWORD  dwReserved[4];
        } MainAVIHeader;
       
I've no idea what MS charge for the vfwdk, but I know its
available when you purchase a Video Blaster Card, and its also
include on the CD that comes with 'Visual Basic MultiMedia'(from
the Coriolis Book Group)
Hope this helps

Peter Haas' VFW and a PC camera demo that describes three different ways to get a single frame in a TBitmap.  http://home.t-online.de/home/PeterJHaas/Download/capdemoc.zip.  Extend this example to select a CODEC:

procedure TMainForm.BtnDlgVideoCompressionClick(Sender: TObject);
begin
  if FCapWnd <> 0 then
    capDlgVideoCompression(FCapWnd);
end;

Toni Martir's notes and complete VFW example (see ShevinE's improvement below).  (Note:  to get Toni's complete example to compile in D3-D5, make sure you can compile with USES OLE2:

Tools | Environment Options | Library | Library Path
D3: C:\Program Files\Borland\Delphi 3\Lib\Delphi2
D4-5: $(DELPHI)\Lib\Delphi2)

Use Lizard.AVI or another AVI file with Toni's example.

ShevinE's improvements to Toni Martir's example (D3-D5 source).  Saves AVI to BMP files as FrameXX.BMP.  Includes VFW.PAS file used in Toni's example.  (Requires USES OLE2 -- see above notes for details.)  [Use Lizard.AVI or another AVI file.]

Delphi import unit for the VFW SDK.  www.swiftsoft.de/free/vfw.zip  is a older version of a VfW header translation.  Ivo Steinmann has edited this unit. A link to the new version is
ftp://delphi-jedi.org/api/vfw.zip (direct) or
http://www.delphi-jedi.org/Jedi:APILIBRARY (indirect).

Component allows to capture images and videos from several  sources (videocams, vcr's, webcams). Has been created using the AVICAP32.dll (from the Win32 API).

Næææ, godmorgen Ziron.

Jeg tror du har misforstået spørgsmålet. Du er måske stadig lidt træt.
Prøv at højreklikke på en .avi og se info man kan få om filen.
Titel, emne, leverandør etc.

:-)

Well jeg var/er ud efter noget lidt letter ende alle de links/componenter der er givet her.
Jeg vil bare lave et simpelt program, der når jeg åbner en avi fil, giver mig "data rate", "resolution", "codecs used".
Men jeg kan sq ikke finde ud af det....

spm lukket :)

nej det skal du ikke gøre :( vil også gerne vide det
