Package install

1.  If a previous TActiveMovie package is already installed, remove it first:

- Components | Install Packages
- Click on "datastead TActiveMovie"
- Click "Remove"
- Click "Yes"
- Click "Ok".
- search for "TAMovie.*" and "AMov*.*" files in your Borland directories and delete them, to be certain that old units will not remain in the search paths (causing later raw errors). 

2.  Install the current package:

- Unzip the archive in a folder of your choice (e.g. c:\amovie)

- According to your Delphi or C++Builder version,
  copy all the Delphi?\*.* or CBuilder?\*.* archive files to the Borland\Delphi?\Imports or \Borland\CBuilder?\Imports directory,

- Run Delphi or C++Builder,

- Select Component | Install packages,

- Press the "Add" button,

- Locate the TAMovie.bpl file in the Imports directory and select it,

- Select Open

- Select Ok

- Check the ActiveX tab in the right of the component palette. The TActiveMovie object should have been added.

DELPHI 4 USERS: Apply the Delphi 4 Update Packs #2 and #3, otherwise you could get an error when installing the component on the palette, or thread errors at runtime. These update packs can be downloaded from http://www.borland.com/devsupport/delphi/downloads/index.html. 

Quick start guide

- place a TActiveMovie component from the ActiveX palette on your Project,

- place a button on your Project. In the ButtonClick event, add the following code:
ActiveMovie1.FileName := 'your media file path or URL';
ActiveMovie1.OpenSync;

- run your project.

Zooming

- place a TActiveMovie component from the ActiveX palette on your Project,

- disable the ShowControls property,

- set the DisplaySize property to mpCustomSize,

- at runtime, change the ActiveMovie1.ZoomSize value from 100 (original size) to the desired percentage.

Single frame capture

Overview

The single frame capture is invoked by calling one of the following functions, according to the destination of the frame:

function CaptureFrameToBmpFile (var FileName: String): WordBool;
function CaptureFrameToJPEGFile (var FileName: String): WordBool;
function CaptureFrameToImage (Image: TImage): WordBool;
function CaptureFrameToBitmap (Bitmap: TBitmap): WordBool;

Multiple frame capture with the Frame Grabber (DirectX8 required)

The frame grabber allows to capture quickly several frames (or all the frames) from only 1 statement call. 

This feature is based on DirectX8, so it won't be available if a previous version of DirectX is installed on the platform where the application runs.

The frame grabber works  asynchronously. That means that you set the grabber parameters, you call FGrabber_CaptureFrameTo one time, and then the captured frames are returned by the OnFGrabberCaptureCompleted event.

Using the frame grabber to capture 1 frame

- set FGrabber_Enabled = true to enable the frame grabber (this must be done before opening the clip),
- open the clip,
- set FGrabber_BurstMode = False do get only 1 frame
- call FGrabber_CaptureFrameTo
- the captured frame is returned by the OnFGrabberCaptureCompleted event.

Using the frame grabber to capture more than 1 frame

- set FGrabber_Enabled = true to enable the frame grabber (this must be done before opening the clip),
- open the clip,
- set FGrabber_BurstMode = true to allow more than 1 frame,
- set FGrabber_BurstCount = the number of frames to capture, or 0 to capture all the frames,
- set FGrabber_BurstInterval = 0 to capture successive frames, or a value n to capture 1 frame each n frames, until BurstCount has been reached.
- call FGrabber_CaptureFrameTo
- the captured frames are returned by the OnFGrabberCaptureCompleted event until BurstCount is reached (if BurstCount = 0, until BurstMode is disabled or the end of the clip has been reached).

FGrabber_CaptureFrameTo parameters

Frames are returned by the OnFGrabberCaptureCompleted event as a TBitmap, a BMP file or a JPEG file according to the Dest parameter passed to the FGrabber_CaptureFrameTo procedure. Dest can take one of the following values:
fc_TBitmap: captures the current frame to a memory bitmap,
fc_BmpFile: captures the current frame to a BMP file,
fc_JpegFile: captures the current frame to a JPEG file according to the JPEGPerformance, JPEGQuality and JPEGProgressiveDisplay values.

File name

When fc_BmpFile or fc_JpegFile is specified in the Dest parameter of the FGrabber_CaptureFrameTo procedure, a file name is automatically created in the StoragePath directory according to the AutoFileName property on a sequential increment (AutoFileName = fn_Sequential) or time basis (AutoFileName = fn_DateTime). This file name used to save the current frame is returned by the OnFGrabberCaptureCompleted event. 

Capture size

The CaptureSize property allows to resize the frame in percent of its original size. 
Remark:
- the capture is faster using a size of exactly 100%, because it is not necessary to resize the bitmap,
- using high zoom values (greater than 100%) may require excessive CPU time.
