how to know when IWMReaderCallback::OnSample() is called no more (end of data)

Hi all,

I am developing an audio player with WMF SDK 11.

I am using an asynchronous WMReader, and IWMReaderAdvanced's user
provided clock.

When playing some files, I cannot detect the end of the audio data at
IWMReaderCallback::OnSample() because cnsSampleTime +
cnsSampleDuration doesn't always reach the total length of the audio
(read from g_wszWMDuration header attribute).

I get WMT_EOF at IWMReaderCallback::OnStatus() but OnSample() will
still be called a few more times afterwards, so OnStatus() events are
useless for this task.

Which would be the correct way to detect that the total length of the
audio has been decompressed (ie. OnSample() is not going to be called
anymore).

Cheers,
Jose
