(Abstract) Report whether more input buffers can be accepted
Parameters
- dwInputStreamIndex
- Input stream number
Return Value
S_OK if the implementor is ready to accept an input buffer, else S_FALSE
Remarks
This method is called by the abstract class. If the implementor has room for another input buffer, it should return S_OK. It is perfectly acceptable for a DMO to only accept one input buffer at a time, and to return S_FALSE until InternalProcessOutput has been called to process the buffer.
