Value Meaning
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.

Comments

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.
