Description |
long |
BitrateSupportedCount |
(Read-only) Gets the current count of supported bitrates. |
long |
Bitrate |
Gets or sets the desired bitrate for the audio stream. This value is in kilobits/second. |
long |
ChannelsSupportedCount |
(Read-only) Gets the current count of audio channels supported. |
long |
Channels |
Gets or sets the channels type (Stereo, 5.1, 7.1). |
long |
SampleRateSupportedCount |
(Read-only) Gets the current count of audio sample rate supported. |
long |
SampleRate |
Gets or sets the desired sample rate. |
long |
BitsPerSampleSupportedCount |
(Read-only) Gets the current count of bits / sample supported. |
long |
BitsPerSample |
Gets or sets the bits per sample. |
index |
Index of desired bitrate value. |
pVal |
Pointer to the long value representing the returned bitrate. |
Gets the supported bitrate value at the specified index. The value returned is measured in kilobits/second. For example, a value of 192 means 192 kbps.
S_OK if successful, < 0 if an error occurred.
bitrate |
A long value representing the bitrate to check. The bitrate should be in kilobits/second. |
pVal |
Pointer to the VARIANT_BOOL value indicating whether or not the bitrate is supported. |
Checks the specified bitrate for support.
S_OK if successful, < 0 if an error occurred.
E_POINTER [0x80004003] pVal is NULL
index |
Index to the channel type. |
pVal |
Pointer to the long variable to receive the channel type value supported at the given index. |
Gets the long value representing the audio channels type supported for the specified index, given the current audio stream bitrate.
Possible values are: 1=Mono, 2=Stereo, 6=5.1 Surround, 8=7.1 Surround.
S_OK if successful, < 0 if an error occurred.
E_POINTER [0x80004003] pVal is NULL
E_INVALIDARG [0x80070057] Index is invalid
channels |
A long value indicating the desired channel type value. 1=Mono, 2=Stereo, 6=5.1 Surround, 8=7.1 Surround. |
pVal |
Pointer to the VARIANT_BOOL value indicating whether or not the channels is supported. |
Gets a boolean value indicating whether or not the current audio stream and bit rate support the desired channel type.
S_OK if successful, < 0 if an error occurred.
index |
Index to the sample rate. |
pVal |
Pointer to the long variable to receive the sample rate value supported at the given index. |
Gets the long value representing the sample rate for the specified index, given the current audio stream bitrate.
S_OK if successful, < 0 if an error occurred.
E_POINTER [0x80004003] pVal is NULL
E_INVALIDARG [0x80070057] Index is invalid
sampleRate |
A long value indicating the sample rate to check. |
pVal |
Pointer to the VARIANT_BOOL value indicating whether or not the sample rate is supported. |
Gets a boolean value indicating whether or not the current audio stream and bit rate support the sample rate.
S_OK if successful, < 0 if an error occurred.
index |
Index to the bits per sample. |
pVal |
Pointer to the long variable to receive the bits per sample value supported at the given index. |
Gets the long value representing the bits per sample for the sample rates associated with the current channel type for the specified index, given the current audio stream bitrate.
S_OK if successful, < 0 if an error occurred.
E_POINTER [0x80004003] pVal is NULL
E_INVALIDARG [0x80070057] Index is invalid
sampleRate |
A long value indicating the bits per sample to check. |
pVal |
Pointer to the VARIANT_BOOL value indicating whether or not the bits per sample is supported. |
Gets a boolean value indicating whether or not the current audio stream and bit rate support the bits per sample.
S_OK if successful, < 0 if an error occurred.
