ENCODER INTERFACES
GetCodecType
Description:
Syntax:
Parameter:
Return Value:
Remarks:
Get the current encoding format
HRESULT GetCodecType(DWORD *pdwCodecType)
pwdCodecType
[out] Pointer to store the current encoding format
S_OK: Successful
E_FAIL: The encoding format is not initialized
E_POINTER: pwdCodecType is NULL pointer
If successful, *pdwCodecType stores the current encoding format
IsSupportedParam
Description:
Syntax:
Parameter:
Return Value:
Remarks:
Query if the parameter type is supported
HRESULT IsSupportedParam(DWORD dwParamType)
dwParamType
[in] Parameter support to query
S_OK: The parameter is supported
E_FAIL: The parameter is not supported
Parameter types are listed in Encoder Parameters
SetParamValue
Description:
Syntax:
Parameter:
Return Value:
Remarks:
Set the value of the specified parameter type. The pData points to a
memory region storing the value of the parameter. The parameter can be a
data structure, which must match the size of the parameter type.
HRESULT SetParamValue(DWORD dwParamType, LPVOID pData)
dwParamType
[in] Parameter to set
pData
[in] This pointer points to memory storing the value(s) of the parameter
S_OK: Successful
E_FAIL: Fail to set the value
(e.g. encoder state does not allow)
E_NOTIMPL: Parameter is not adjustable
E_UNEXPECTED: The encoding format is not initialized yet.
E_POINTER: pData is NULL pointer
Parameter types are listed in Encoder Parameters
