This is a helper function to determine whether the video will be recompressed or is pre-encoded. It can be used by the application designer to disable output video encoding options if the pre-encoded video is used by the stream.
The function will only return VARIANT_TRUE if IltmsLiveStream::get_UseDeviceEncoding is VARIANT_TRUE and the video device has output-compatible encoding.
You must lock the capture devices with IltmsLiveStreamDevConfig::LockDevices before calling this function.
Win32, x64.
