AVISaveOptions

The AVISaveOptions function retrieves the save options for a file and returns them in a buffer.

BOOL AVISaveOptions(
  HWND hwnd,                         
  UINT uiFlags,                      
  int nStreams,                      
  PAVISTREAM * ppavi,                
  LPAVICOMPRESSOPTIONS * plpOptions  
);
 

Parameters

hwnd

Handle of the parent window for the Compression Options dialog box.

uiFlags

Flags for displaying the Compression Options dialog box. The following flags are defined:

ICMF_CHOOSE_KEYFRAME

Displays a Key Frame Every dialog box for the video options. This is the same flag used in the ICCompressorChoose function.

ICMF_CHOOSE_DATARATE

Displays a Data Rate dialog box for the video options. This is the same flag used in ICCompressorChoose.

ICMF_CHOOSE_PREVIEW

Displays a Preview button for the video options. This button previews the compression by using a frame from the stream. This is the same flag used in ICCompressorChoose.

nStreams

Number of streams that have their options set by the dialog box.

ppavi

Address of an array of stream interface pointers. The nStreams parameter indicates the number of pointers in the array.

plpOptions

Address of an array of pointers to AVICOMPRESSOPTIONS structures. These structures hold the compression options set by the dialog box. The nStreams parameter indicates the number of pointers in the array.

Return Values

Returns TRUE if the user pressed OK, FALSE for CANCEL, or an error otherwise.

Remarks

This function presents a standard Compression Options dialog box using hwnd as the parent window handle. When the user is finished selecting the compression options for each stream, the options are returned in the AVICOMPRESSOPTIONS structure in the array referenced by plpOptions. The calling application must pass the interface pointers for the streams in the array referenced by ppavi.

An application must allocate memory for the AVICOMPRESSOPTIONS structures and the array of pointers to these structures.
