Also known as an encoder , this is a module or algorithm to compress data. Playing that data back requires a decompressor , or decoder .
Also known as compressor, this is a module or algorithm to compress data. Playing that data back requires a decompressor, or decoder.
Also known as a decoder, this is a module or algorithm to decompress data.
Also known as a decompressor, this is a module or algorithm to decompress data.
The format to be used for the converted file. This includes the file format, any special settings used by that format, and which audio and/or video codec is to be used for the conversion, and any special settings used by the codecs.
A COmpressor combined with a DECompressor, or encoder and a decoder, which allows you to both compress and decompress that same data.

HRESULT IltmmTargetFormat_get_RecommendedAudioCompressor(Format, pVal) |
|
C++ Syntax |
HRESULT get_RecommededAudioCompressor(pVal) |
|
IltmmTargetFormat *Format; |
/* pointer to an interface */ |
|
BSTR *pVal; |
/* pointer to a string */ |
Retrieves the recommended audio compressor for the currently selected target format .
|
Parameter |
Description |
|
Format |
Pointer to an IltmmTargetFormat interface. |
|
pVal |
Pointer to a variable that will receive the name of the recommended audio compressor for the currently selected target format. |
Returns
|
S_OK |
The function was successful. |
|
<> S_OK |
An error occurred. Refer to the Error Codes or the HRESULT error codes in the DirectShow documentation. |
Comments
Currently, the toolkit does not recommend compressors for all formats, so if the returned string is empty, then there is no recommended audio compressor for the selected target format.
If the method succeeds, the caller must free the returned BSTR by calling the SysFreeString function.
