C++ | HRESULT get_IsAudioEncoded(pVal) |
Pointer to an IltmsLiveStreamDevConfig interface.
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.

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.
Win32, x64.
