Access violation on Graph.CoCreateInstance
Fri, 19 Sep 2008 12:00:57 +0200
Hi,
I have player application which first initialize all filters add to graph
and go to run mode. That goes well. Than when i press stop it goes to stop
mode and release all filters, mediaevent, mediacontrol and graph (in that
order). Now when i call play again i get access violation on:
hr = pGraph.CoCr ...

Last sample missing
Fri, 19 Sep 2008 00:18:19 +0100
I have a filter graph with my own file source filter which has a
CSourceStream derived output pin. This feeds the MPEG demux filter which has
2 output pins which are both eventually connected to VMR9s.
This works OK except that the last sample from one of the MPEG PIDs does not
get renderered. At first I th ...

GMFBridge, Windowless VMR and Multiple Monitors
Thu, 18 Sep 2008 14:26:01 -0700
I have a simple application with a capture graph that reads a file and throws
the samples through GMFBridge to a render graph with a windowless VMR9. (The
bridge isn't necessary here, but this is the basis for something more
complicated and I figured I should get the basics down first.) I'm not trying
to str ...

DirectShow timestamps vs RTP
Thu, 18 Sep 2008 06:50:37 -0700 (PDT)
I've been working for some time on a set of DS filters that send and
receive an RTP stream (audio or video). Until now I was sending the
timing information from the MediaSamples along with the stream to
ensure timely playback and synchronization between 2 different
streams. Since the stream should be platform in ...

VMR9 Run() Halt - Presentation Times?
Wed, 17 Sep 2008 17:21:32 +0200
Hi all - I've been working on this for many hours now and haven't
figured it out. Here's the graph:
FSF -> Demux -> Decoder -> My Filter -> VMR9
On IMediaControl::Run() my filter begins receiving samples before Run()
has been called in my filter. The incoming samples have sensible
presentation times. Ho ...

DV Decoder to ASF Writer - Forcing interlaced encoding
Tue, 16 Sep 2008 13:59:21 -0700 (PDT)
From the MSDN article, http://msdn.microsoft.com/en-us/library/aa384751(VS.85).aspx,
I see what is needed at the encoder side to enable interlaced
encoding.
Once this is done, will the ASF Writer filter limit its media type
connections to only accept interlaced input? Or must more be done
such as specifying ...

Source Filter using UserMode DShow Filter and Plain Kernel Driver
Mon, 15 Sep 2008 22:32:07 -0700 (PDT)
Hi
I want to build DirectShow Source Filter in user mode which will talk
with hardware using ioctls to normal WDM Kernel Driver (i.e. it will
not be implementing avstream class)
Is the above design feasible? What kinds of bottleneck it may result?
and would there be any effect on getting WHQL test to PASS (i. ...

DMO manually created for graph with wrapper?
Mon, 15 Sep 2008 16:01:13 -0700 (PDT)
I have a DMO that I've created that I would like to use in a graph in
a 2nd application. I would like to not have to register the DMO but
to create it while building the graph (create it internally to the 2nd
application). It looks like the DMOWrapper can't take an instantiated
COM object but a ref to a classi ...

Iam developing a video editing program using the directshow editing
services (DES), and almost finished it with no problems.
my question is : how to use the source clip more than once in the
timeline of the graph? because loading the same source clip once for
audio and once for video, and maybe loading ...
