Hi Matthew,
Yes, i am seeing a NewStream() call when test case fails. Also i got the
reason why Pin was not getting instantiated. Its because, my driver
currently supports only one stream instantiation at a time.If there is try
of creating multiple streams then my driver is returning
STATUS_INVALID_DEVICE_REQUEST status from NewStream() function. So i
removed this handling and allowed mutliple streams to be created and test
case "Data Intersection Test\Render Streaming\Check Supported Formats" got
Pass. But now i am getting more failures in following test cases:
1) Standard Streaming\Rendering Pin Tests\Reset Pin while streaming data
KSPIN_DATAFLOW_IN pin is currently in state KSSTATE_PAUSE; want it to
be in state KSSTATE_RUN
Setting KSPIN_DATAFLOW_IN pin to state KSSTATE_RUN
Position reported before issuing KSRESET_BEGIN = 121 bytes
KSPIN_DATAFLOW_IN pin is currently in state KSSTATE_RUN; want it to be
in state KSSTATE_RUN
Resetting Pin state: IOCTL_KS_RESET_STATE (KSRESET_BEGIN)
Position reported after issuing KSRESET_BEGIN = 0 bytes
Submitting IOCTL_KS_WRITE_STREAM IRP ...
GetLastError did not return ERROR_IO_PENDING even though the pin is
paused
[ GetLastError() returned 21 (0x15) - The device is not ready. ].
FAIL: Failed WriteData(Render)/ReadData(Capture) to see if pin position
is moving or not.
2) Standard Streaming\Rendering Pin Tests\Streaming buffer from different
threads
FAIL: Position (1600) is less than the amount of data streamed (3200).
3) Standard Streaming\Rendering Pin Tests\Calling get position from the
different thread
4) Standard Streaming\Rendering Pin Tests\Streaming with 2 different
instance of the pin.
Wave Format used for instantiation:
Format.wFormatTag = WAVE_FORMAT_EXTENSIBLE
Format.nChannels = 2
Format.nSamplesPerSec = 22050
Format.nAvgBytesPerSec = 88200
Format.nBlockAlign = 4
Format.wBitsPerSample = 16
Format.cbSize = 22
wValidBitsPerSample = 16
dwChannelMask = KSAUDIO_SPEAKER_STEREO (0x3)
SubFormat =
KSDATAFORMAT_SUBTYPE_PCM{00000001-0000-0010-8000-00AA00389B71}
CKsPin::Instantiate. Failed to instantiate KSPIN_DATAFLOW_IN pin!
KsCreatePin returned = 0x00000057
[ GetLastError() returned 87 (0x57) - The parameter is incorrect. ].
PreparePin: Unable to instantiate pin.
Can you please help me in above failures ? What could be the reasons behind
these failures ? Here i don't understand one thing is that, when i doesn't
allow multiple streams to be instantiated in my driver then above mentioned
test cases got skipped while wave test and if i allow multiple streams then
i got failure for this test cases.
Regarding your another question, my driver supports WAVE_FORMAT_PCM with
maximum channels 2, max sample rate 64000, min sample rate 4000.
Thanks.
