avstream driver registering in Audio Capture Sources category?

NTDEV
1

Hi All,
I want AVStream driver to be registered in the Audio Capture
Sources category. I made changes in .inf file and added one more catagory
KSCATAGORY_AUDIO/RENDER. But still it does not work. Is there something more
that I need to mention ??

Did you change the data structures in the device? The KSFILTER_DESCRIPTOR
contains a category list that gets copied to the registry when the
filter factory is created.

Hi Tim,
I have done any changes in KSFILTER_DESCRIPTOR but I have added
one more GUID in CaptureFilterCatagories array like,

const
GUID
CaptureFilterCategories [CAPTURE_FILTER_CATEGORIES_COUNT] = {
STATICGUIDOF (KSCATEGORY_VIDEO),
STATICGUIDOF (KSCATEGORY_AUDIO),
STATICGUIDOF (KSCATEGORY_RENDER),
STATICGUIDOF (KSCATEGORY_CAPTURE)
};

and it is added in KSFILTER_DESCRIPTOR in this way ,
const
KSFILTER_DESCRIPTOR
CaptureFilterDescriptor = {
&CaptureFilterDispatch,
NULL,
KSFILTER_DESCRIPTOR_VERSION,
KSFILTER_FLAG_DISPATCH_LEVEL_PROCESSING,
&KSNAME_Filter,
DEFINE_KSFILTER_PIN_DESCRIPTORS (CaptureFilterPinDescriptors),

DEFINE_KSFILTER_CATEGORIES
(CaptureFilterCategories),//*******************************

DEFINE_KSFILTER_NODE_DESCRIPTORS_NULL,
DEFINE_KSFILTER_DEFAULT_CONNECTIONS,

NULL
};

I have also modified inf file, but that too does not work. My inf file looks
like this
[avssamp.RunOnce.AddReg]
HKLM,%RunOnce%,“avssamp.Reader.Capture”,“rundll32.exe
streamci,StreamingDeviceSetup
%avssamp.DeviceId%,%KSNAME_Filter%,%KSCATEGORY_CAPTURE%,%17%\avssamp.inf,avssamp.Reader.Install”
HKLM,%RunOnce%,“avssamp.Reader.Video”,“rundll32.exe
streamci,StreamingDeviceSetup
%avssamp.DeviceId%,%KSNAME_Filter%,%KSCATEGORY_VIDEO%,%17%\avssamp.inf,avssamp.Reader.Install”
HKLM,%RunOnce%,“avssamp.Reader.Audio”,“rundll32.exe
streamci,StreamingDeviceSetup
%avssamp.DeviceId%,%KSNAME_Filter%,%KSCATEGORY_AUDIO%,%17%\avssamp.inf,avssamp.Reader.Install”

[Strings]
KSCATEGORY_AUDIO=“{6994AD04-93EF-11D0-A3CC-00A0C9223196}”
KSCATEGORY_RENDER=“{65E8773E-8F56-11D0-A3B9-00A0C9223196}”
KSCATEGORY_CAPTURE=“{65E8773D-8F56-11D0-A3B9-00A0C9223196}”

Is it the correct way to do it ? What else do we need to mention ?

Now device is visible in listing of device manager under Sound, Video, and

Well, you cannot have one single filter that is both a capture source
and a renderer. That doesn’t make sense. Do you actually have two
separate filters here?

Well, I tried all combinations, 2 separate filters / single capture / single
renderer but still my device is not included Audio Capture Sources. I also
tried with defining my own connections and nodes in KSFILTER_DESCRIPTOR
rather than using default ones, but still the same problem. :-(( . I simply
want my device to be included in Audio Capture sources list by using
AVStream.

Well, I’ve seen KSCATEGORY_AUDIO work for capture filters, although I’ve
not tried it for render filters.

Hi,
Thanks for reply.
Even though its for capture filters its fine for me. But doing what

A number of the WDK samples in the src\audio directory do this. The
fmsynth sample is an audio render device; it uses KSCATEGORY_AUDIO and
KSCATEGORY_RENDER. The dmusuart sample does audio render and capture.
In your DDK src\audio folder, search for “OF(KSCATEGORY”.
