static

The optional callback for GstTensorFilterFramework.

Definition at line 212 of file tensor_filter_custom.c.

custom_invoke()

static int custom_invoke ( const GstTensorFilterProperties *  prop, void **  private_data, const GstTensorMemory *  input, GstTensorMemory *  output  )

static

The mandatory callback for GstTensorFilterFramework.

Parameters

	prop	The properties of parent object
[in]	input	The array of input tensors
[out]	output	The array of output tensors

Returns

0 if OK. non-zero if error.

Definition at line 167 of file tensor_filter_custom.c.

custom_loadlib()

static int custom_loadlib ( const GstTensorFilterProperties *  prop, void **  private_data  )

static

Load the custom library. Will skip loading if it's already loaded.

Returns

0 if successfully loaded. 1 if skipped (already loaded). -1 if error

Todo:

: Check the integrity of filter->data and filter->model_file, nnfw

Todo:

Double check if this check is really required and safe
