BMP in AVI wandeln

[Ydobon]

Das habe ich noch in meiner Rumpelkammer gehabt. Schon ein paar Jahre alt, nie so richtig gut, aber vielleicht kannst du damit etwas anfangen.

Delphi-Quellcode:

procedure TForm1.Button1Click(Sender: TObject);
var dir: String;
    ts: TSearchRec;
    datlist: TStringList;
    tfs: TFileStream;
    pfile: IAVIFile;
    pavi: IAVIStream;
    psi: TAVISTREAMINFO;
    Bfi: BITMAPFILEHEADER;
    bmi: PBITMAPINFO;
    bits: PByteArray;
    i, bmisize: Integer;
begin
  if Not SelectDirectory('Bitmapverzeichnis wählen', 'c:\tempo', dir) then Exit;
  if FindFirst(dir+'\*.bmp', faAnyFile, ts)<>0 then Exit;
  if Not SaveDialog1.Execute then Exit;
  datlist:=TStringList.Create;
  try
    datlist.Add(ts.Name);
    while FindNext(ts)=0 do datlist.Add(ts.Name);
    datlist.Sort;
  finally
    FindClose(ts);
  end;
  Label1.Caption:=IntToStr(datlist.Count);
  tfs:=TFileStream.Create(dir+'\'+datlist[0], fmOpenRead);
  tfs.Read(bfi, SizeOf(BITMAPFILEHEADER));
  bmisize:=bfi.bfOffBits-SizeOf(BITMAPFILEHEADER);
  GetMem(bmi, bmisize);
  tfs.Read(bmi^, bmisize);
  GetMem(bits, bmi.bmiHeader.biSizeImage);
  tfs.Read(bits^, bmi^.bmiHeader.biSizeImage);
  AVIFileInit;
  AVIFileOpen(pfile, PChar(SaveDialog1.FileName), OF_CREATE OR OF_WRITE, NIL);
  ZeroMemory(@psi, SizeOf(TAVIStreamInfo));
  with psi do
  begin
    fccType:=streamtypeVIDEO;
    fccHandler:=mmioFourcc(#0, 'D', 'I', 'B');
    dwScale:=1;
    dwRate:=25;
    dwLength:=datlist.Count;
    dwSuggestedBufferSize:=bmi.bmiHeader.biSizeImage;
    rcFrame:=Rect(0, 0, bmi.bmiHeader.biWidth, bmi.bmiHeader.biHeight);
    szName:='Noname';
    dwQuality:=$FFFFFFFF;
    dwSampleSize:=bmi.bmiHeader.biSizeImage;
  end;
  AVIFileCreateStream(pfile, pavi, psi);
  AVIStreamSetFormat(pavi, 0, bmi, bmisize);
  For i:=0 to datlist.Count-1 do
  begin
    AVIStreamWrite(pavi, i, 1, bits, bmi.bmiHeader.biSizeImage, AVIIF_KEYFRAME, NIL, NIL);
    tfs.Free;
    tfs:=TFileStream.Create(dir+'\'+datlist[i], fmOpenRead);
    Image1.Picture.Bitmap.LoadFromStream(tfs);
    tfs.Seek(bfi.bfOffBits, soFromBeginning);
    tfs.Read(bits^, bmi.bmiHeader.biSizeImage);
    Label2.Caption:=IntToStr(i+1);
    Application.ProcessMessages;
  end;
  tfs.Free;
  FreeMem(bits);
  datlist.Free;
end;
