Queries whether the current capture configuration has pre-encoded audio.
Parameter |
Description |
pLiveStreamDevConfig |
Pointer to an IltmsLiveStreamDevConfig interface. |
pVal |
Pointer to a boolean variable that indicates whether the audio is pre-encoded. If VARIANT_TRUE, the audio is pre-encoded. If VARIANT_FALSE, the audio is not pre-encoded. |
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. |
This is a helper function to determine whether the audio will be recompressed or is pre-encoded. It can be used by the application designer to disable output audio encoding options if the pre-encoded audio is used by the stream.
The function will only return VARIANT_TRUE if IltmsLiveStream::get_UseDeviceEncoding is VARIANT_TRUE and the audio device has output-compatible encoding.
Before calling this function, you must lock the capture devices with IltmsLiveStreamDevConfig::LockDevices.
