Parameter

Description

pMultiStreamTarget

Pointer to an IltmmMultiStreamTarget interface.

lTimeout

Time-out interval, in milliseconds. The time the function will wait for a sample to be ready. If the time elapses and no sample is ready, the function will return a time-out error code. If lTimeOut is -1, the function's time-out interval never elapses.

Stream

Pointer to a variable that will receive the stream number for which the sample is indicated as ready. A stream value of 1 indicates an invalid stream.

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

The function must be called in the running state; calling it in the stopped state or after the end of stream is reached will return a wrong state code.
