Formats Used by vvas_xinfer - Formats Used by vvas_xinfer - 6.3 English - XD056

The vvas_xinfer element selects the tensor format from three values: model-format from the JSON configuration, the model tensor layout, and the tensor data type. GStreamer logs and caps use the names in the last column.

vvas_xinfer does not select BGR with NCHW for FLOAT32 or INT8 models. GRAY_BF16, GRAY_FP16, and GRAY_FLOAT may appear in caps for tensor compatibility, but they are not selected for RGB or BGR model configurations.
