Hello
I've written a simple filter graph that catches packets from MPEG-2
transport stream coming from DVB-T card. This filter is based on
IMpeg2Demultiplexer, that is connceted from one side to BDA Network
Tuner and from the second to my data filter that inherits from
CBaseFilter.
The filter graph at the beginning works properly, but when I change
the channel a few times (in other words - when I map and unmap some
PIDs) I get an exception like "access violation in blah blah blah...".
When I tried to debug this exception I could only read that is caused
in file mpg2splt.ax or ntdll.dll and nothing else (no source code was avalailable).
My friend told me that I have to synchronize all the operations
connected physically with the card, but it didn't help. Did anyone
have such problem? I have no idea how to correct this bug. Any help
will be appreciated...
