Member Data Documentation

close

void(* _NNStreamerExternalConverter::close) (void **priv_data)

tensor_converter will call this to close subplugin.

Parameters

[in]

private_data

frees private_data and set NULL.

Definition at line 82 of file nnstreamer_plugin_api_converter.h.

convert

GstBuffer*(* _NNStreamerExternalConverter::convert) (GstBuffer *in_buf, GstTensorsConfig *config, void *priv_data)

Convert the given input stream to tensor/tensors stream.

Parameters

[in]	buf	The input stream buffer
[out]	config	tensors config structure to be filled

Return values

Return	input buffer(in_buf) if the data is to be kept untouched.
Return	a new GstBuf if the data is to be modified.

Definition at line 48 of file nnstreamer_plugin_api_converter.h.

get_out_config

gboolean(* _NNStreamerExternalConverter::get_out_config) (const GstCaps *in_caps, GstTensorsConfig *config)

Set the tensor config structure from the given stream frame.

Parameters

[in]	in_caps	The input (original/media data) stream's metadata
[out]	config	The output (tensor/tensors) metadata

Return values

Return

True if get caps successfully, FALSE if not.

Definition at line 58 of file nnstreamer_plugin_api_converter.h.

name

const char* _NNStreamerExternalConverter::name

Definition at line 45 of file nnstreamer_plugin_api_converter.h.

open

int(* _NNStreamerExternalConverter::open) (const gchar *script_path, void **priv_data)

tensor_converter will call this to open subplugin.

Parameters

[in]	script_path	script path of the subplugin.
	[in/out]	private_data A subplugin may save its internal private data here. The subplugin is responsible for alloc/free of this pointer. Normally, open() allocates memory for private_data.

Returns

0 if ok. < 0 if error.

Definition at line 75 of file nnstreamer_plugin_api_converter.h.

query_caps

GstCaps*(* _NNStreamerExternalConverter::query_caps) (const GstTensorsConfig *config)

Filters (narrows down) the GstCap (st) with the given config.

Parameters

[in]

config

The config of output tensor/tensors

Return values

Return

subplugin caps (if config is NULL, return default caps)
