Parameter

Description

pConvert

Pointer to an IltmmConvert interface.

Value that is one of the ltmmVideoRenderer Constants.

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 function sets the preferred video renderer. The default value is ltmmVideoRenderer_VMR9.

LEADTOOLS will automatically try the assigned video renderer preference. If that fails, then LEADTOOLS will step down to an earlier version of the renderer, until all renderers are exhausted.

If you are on a system that supports VMR7 or VMR9, then the Legacy renderer is not automatically attempted unless the user explicitly sets Legacy as a preference. This prevents screen flashing on these systems.
