Parameter

Description

pLiveStreamDevConfig

Pointer to an IltmsLiveStreamDevConfig interface.

pVal

Pointer to a boolean variable that indicates whether the video is pre-encoded. VARIANT_BOOL indicates that the video is pre-encoded. Otherwise, the value is VARIANT_FALSE.

Returns

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.
