Bug:: No known bugs except for NYI items

Todo:: Add "event/signal" to reload FILL_WITH_FILE* file??? (TBD)

The output dimension is SAME with input dimension.

Enumeration Type Documentation

◆ tensor_if_behavior

enum tensor_if_behavior

Behaviors that may fit in THEN and ELSE.

FILL_WITH_FILE, FILL_WITH_FILE_RPT, and REPEAT_PREVIOUS_FRAME caches an output frame and thus, may consume additional memory and incur an additional memcpy.

Enumerator
TIFB_PASSTHROUGH	The input frame becomes the output frame
TIFB_SKIP	Do not generate output frame (frame skip)
TIFB_FILL_ZERO	Fill output frame with zeros
TIFB_FILL_VALUES	Fill output frame with a user given value
TIFB_FILL_WITH_FILE	Fill output frame with a user given file (a raw data of tensor/tensors) If the filesize is smaller, the reset is filled with 0
TIFB_FILL_WITH_FILE_RPT	Fill output frame with a user given file (a raw data of tensor/tensors) If the filesize is smally, the file is repeatedly used
TIFB_REPEAT_PREVIOUS_FRAME	Resend the previous output frame. If this is the first, send ZERO values.
TIFB_TENSORPICK	Choose nth tensor (or tensors) among tensors
TIFB_END

Definition at line 79 of file gsttensor_if.h.

◆ tensor_if_compared_value

enum tensor_if_compared_value

Compared_Value.

Enumerator
TIFCV_A_VALUE	Decide based on a single scalar value of tensors
TIFCV_TENSOR_TOTAL_VALUE	Decide based on a total (sum) value of a specific tensor
TIFCV_ALL_TENSORS_TOTAL_VALUE	Decide based on a total (sum) value of of tensors or a specific tensor
TIFCV_TENSOR_AVERAGE_VALUE	Decide based on a average value of a specific tensor
TIFCV_ALL_TENSORS_AVERAGE_VALUE	Decide based on a average value of tensors or a specific tensor
TIFCV_CUSTOM	Decide based on a user defined condition
TIFCV_END

Definition at line 42 of file gsttensor_if.h.

◆ tensor_if_operator

enum tensor_if_operator

OPERAND.

Enumerator
TIFOP_EQ	==
TIFOP_NE	!=
TIFOP_GT
TIFOP_GE	>=
TIFOP_LT	<
TIFOP_LE	<=
TIFOP_RANGE_INCLUSIVE	in [min, max]
TIFOP_RANGE_EXCLUSIVE	in (min, max)
TIFOP_NOT_IN_RANGE_INCLUSIVE	not in [min, max]
TIFOP_NOT_IN_RANGE_EXCLUSIVE	not in (min, max)
TIFOP_END

Definition at line 60 of file gsttensor_if.h.

◆ tensor_if_srcpads

enum tensor_if_srcpads

Which src pad.

Enumerator
TIFSP_THEN_PAD
TIFSP_ELSE_PAD

Definition at line 96 of file gsttensor_if.h.
