Testcap & MPEG2-TS [Device Drivers]

Hi all,

I'm developing a Stream Class minidriver to catch MPEG2-TS from a USB-TV
box. I modified Testcap, sample code of DDK. Then I use GraphEdit to connect
my filter to VMR. Kernel message shows that system loads mpg2dmx to open my
stream. But after receiving 3 SRB_GET_DATA_INTERSECTION commands, an error
message is shown as: "These filters can't agree on a connection. Verify type
compatibility of input pin and output pin."
Please help me to check out my format definition. What's wrong with it?
Thanks!

Your format description is wrong.

You either tell that it is transport stream and that's where you use
KS_DATARANGE with
> STATIC_KSDATAFORMAT_TYPE_STREAM, // aka. MEDIATYPE_Stream
> STATIC_KSDATAFORMAT_TYPE_MPEG2_TRANSPORT, //MEDIASUBTYPE MPEG2

Or you tell the system that you have MPEG2 video and that's when you use
KS_DATARANGE_MPEG2_VIDEO and all those MPEG2 goodies.

So change the descriptor to simple one (see below) and it should work.

static KS_DATARANGE StreamFormatMPEG2_Capture =
{
// KSDATARANGE
{
sizeof (KS_DATARANGE ), // FormatSize
0, // Flags
0, // SampleSize
0, // Reserved

STATIC_KSDATAFORMAT_TYPE_STREAM, // aka. MEDIATYPE_Stream
STATIC_KSDATAFORMAT_TYPE_MPEG2_TRANSPORT, //MEDIASUBTYPE MPEG2
TRANSPORT,
STATIC_KSDATAFORMAT_SPECIFIER_NONE // aka. None
};

-- Max.

Hi Max,

Thanks for your suggestion.
But my capture pin still can't be connect with VMR in GraphEdit, even after
I modified the structure just like your code. Maybe I don't process
SRB_GET_DATA_INTERSECTION in a correct way? It's complicated to fill all data
structures for separate command. Can you supply any sample code that can
capture TS stream by Stream Class minidriver for me?
Thanks again.

I have no samples that I can share on this subject.
Do you have MPEG2 decoder software on your machine? You can't hook MPEG2TS
output to VMR. It has to go via MPEG2 Demux and MPEG2 A/V Decoders.
