RE: CEPlayer Fast Rewind doesn't work
Broofus
CEPlayer issues the put_Rate() call and where the error message box is
displayed with all of the Debug Zones in quartz.dll enabled and these are the
only prints I got:
275153 PID:4c6000e TID:4c7000a CFGControl::CImplMediaSeeking::GetRate()
275154 PID:4c6000e TID:4c7000a CFGControl::CImplMediaSeeking::SetRate()
It doesn't look like a single call is issued to my demux, which makes me
believe the problem is in Microsoft code that perhaps needs to be
overwridden. I'm confused as to where this error is coming from or how to
debug this any further.
Would appreciate any help.

format? After you render the file, can you use
IMediaSeeking::CheckCapabilities to see if AM_SEEKING_CanSeekBackwards is
supported or not? If not, SetRate with negative rates will return invalid
argument error. For details, check out
http://msdn2.microsoft.com/en-us/library/aa921453.aspx.

I have the following custome decoders:
Mpeg1/2, Mpeg4, DivX, and WMV9
and the following custom demuxers:
Mpeg1/2, Mpeg4, and AVI
If I try to use any of my demuxers I can not do fast rewind. But using the
MS demuxers everything works fine. So for instance WMV works because we use
the ASF splitter provided by MS, but if I play WMV in AVI container it
doesn't. Previously all of these filters worked fine in WinCE 5.0. Upon
testing them in WinCE 6.0 the fast rewind issue was encountered.
I have done some more debugging and have found that in
CImplMediaSeeking::SetRate() there is some sort of check to see if the
desired rate is less than some number (this is assembly since I don't have
the sources, so I'm not sure exactly where this number comes from). That
returns TRUE and causes the E_INVALIDARG error message. If I change the
return value to FALSE the graph is then halted and the rate is changes.
Appears to be a check to see if the desired rate is smaller than the minimum
rate.
This seems to indicate that I'm not reporting the ability to play backwards.
I would have thought that the capabilities would be determined in the
GetCapabilities() funtion. This is what I currently have and it doesn't work:
class CBaseSeeking : public CUnknown, public IMediaSeeking, public
IAMExtendedSeeking
CBaseSeeking::GetCapabilities()
{
*pCapabilities = AM_SEEKING_CanSeekAbsolute |
AM_SEEKING_CanSeekForwards |
AM_SEEKING_CanSeekBackwards |
AM_SEEKING_CanGetStopPos |
AM_SEEKING_CanPlayBackwards | AM_SEEKING_CanGetCurrentPos
| AM_SEEKING_CanDoSegments |
AM_SEEKING_CanGetDuration;
return S_OK
Broofus
is not called, but instead CImplWMSeeking::SetRate(). If you step through
this assembly there is only a check to see if the desired rate is equal to
some number (I'm assuming the current rate) and if it's greater than some
other number (Max speed?). There is no check to see if the desired rate is
less than something as you find in the CImplMediaSeeking implementation.
I don't understand how to override this function as is being done for WMV.
For example in my AVI demux I have overridden SetRate() functions as follows:
class CBaseDemuxFilter : public CBaseFilter
HRESULT CBaseDemuxFilter::SetRate(double dRate)
class CDemuxInputPin : public CBaseInputPin
HRESULT CDemuxInputPin::SetRate(int nRate, BOOL bReStartPuller)
class CAVIDemux : public CBaseDemux
HRESULT CAVIDemux::SetRate(double dRate)
class CBaseSeeking : public CUnknown, public IMediaSeeking, public
IAMExtendedSeeking
STDMETHODIMP CBaseSeeking::SetRate(double dRate)
Am I missing something?

the graph which has the implementation. Since the WM source filter reports
the right seeking capabilities, the filter graph manager knows it supports
rewinding and forwards calls to it. Somehow your demuxers were not exposing
the caps correctly, so the filter graph manager responded the seeking calls
with no actions because it didn't know your demuxer's capabilities.
The check in the SetRate is to make sure you couldn't pass a negative rate
if the filters don't support it. But from your code, it did support
AM_SEEKING_CanPlayBackwards. A couple of things you can try is:
1. After the graph is built, use IMediaSeeking::GetCapabilities to see
if AM_SEEKING_CanPlayBackwards is supported.
2. If the result is not supported, check to see how many filters in
your pipeline support IMediaSeeking interface and make sure only one filter
exposing IMediaSeeking.

implement it on the output pin of the demuxer? From the directx
documentation, "The application queries the Filter Graph Manager for
IMediaSeeking and uses it to issue seek commands. The Filter Graph Manager
distributes each seek command to all of the renderer filters in the graph.
Each renderer passes the command upstream, through the output pins of the
upstream filters, until it reaches a filter that can execute the seek"
Also please check out information at
http://msdn2.microsoft.com/en-us/library/aa930719.aspx to see if you
implemented the interface correctly.

and no longer matches the published documentation. A filter that
works on WinCE 5.0 and WinXP no longer is able to rewind on WinCE
6.0. Also sample applications that can rewind on WinCE5.0 and WinXP
can no longer rewind either since the negative rates are not making it
through the directshow framework to the filters themselves.
Their is a new check done for negative rates, that didn't exist
previously or the conditions for the check have changed. Could you
let us know why the check was added or what conditions have changed
that cause the check to happen now when it doesn't with WinCE 5.0
directshow framework or the WinXP Directshow framework?
Thanks.
