EC_COMPLETE notification

Question

Hello,

I have written a custom renderer (inherits from CBaseFilter) which writes received samples into shared memory.
Basically, this filter is connected to a file reader:

File reader (async) -> Color space converter -> custom filter (renderer)

My problem is that I never receive any EC_COMPLETE notification from the graph builder, though I can reveive other notifications (EC_ACTIVATE, EC_NEED_RESTART, etc.). I guess something is missing in my implementation. I tried to do like this in the implementation of my input pin (inherits from CBaseInputPin):

STDMETHODIMP CInputPin::EndOfStream()
{
	m_pFilter->NotifyEvent( EC_COMPLETE, 0, (LONG_PTR)m_pFilter );
	return CBaseInputPin::EndOfStream();
}

But it doesn't work.

What am I missing?

Cheers.

Answer 1

STDMETHODIMP CInputPin::EndOfStream()
{
    return m_pFilter->NotifyEvent( EC_COMPLETE, 0, (LONG_PTR)(IBaseFilter *)m_pFilter );
}

No need to call the base class, it does nothing.

Hello Michel,

I tried what you said, but it doesn't change anything.
Does my custom renderer has to do something special?

Answer 3

Hi,

I'm back with this problem, I'm still stuck.
The NotifyEvent method return S_OK, but my application isn't noticed. Am I missing something ?

Thanks for your help.

Answer 4

I finally got it!

I don't know why (I didn't notice it in the documentation), but my filter has to implement the IMediaSeeking interface. So I now receive the EC_COMPLETE notification!
