Function Documentation

tivxVideoDecoderNode()

VX_API_ENTRY vx_node VX_API_CALL tivxVideoDecoderNode	(	vx_graph	graph,
		vx_user_data_object	configuration,
		vx_user_data_object	input_bitstream,
		vx_image	output_image
	)

[Graph] Creates a VIDEO_DECODER Node.

Parameters

[in]	graph	The reference to the graph.
[in]	configuration	The input object of a single params structure of type tivx_video_decoder_params_t.
[in]	input_bitstream	The input object of a vx_uint8 buffer. The vx_user_data_object should be sized as per worst case (uncompressed) bitstream size. For each frame of input, the TIVX_USER_DATA_OBJECT_VALID_SIZE attribute should be set on the input_bitstream vx_user_data_object to reflect the size of the specific bitstream buffer frame. Must be formatted as an H264 i-frame only stream.
[out]	output_image	Decoded output. Use VX_DF_IMAGE_NV12 dataformat. QCIF resolution (176x144) is not supported.
