IltmsLiveStreamDevConfig::get_IsVideoEncoded

#include "ltms.h"

C Syntax	HRESULT IltmsLiveStreamDevConfig_get_IsVideoEncoded(pLiveStreamDevConfig, pVal)
C++ Syntax	HRESULT get_IsVideoEncoded(pVal)

IltmsLiveStreamDevConfig pLiveStreamDevConfig;	pointer to an interface
VARIANT_BOOL pVal;	pointer to boolean

Queries whether the current capture configuration has pre-encoded video.

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.
