A function call to make tensors from collected pads It decide which buffer is going to be used according to sync option.

Returns: True to push buffer.

This would be an internal logic error. in_configs should be already confirmed valid at the negotiation phase and this function should be called in a running pipeline. If new sync mode is enabled (e.g., handle output when a pad gets new buffer), this may cause unexpected exception.

These are internal logic error. If given inputs are incorrect, the negotiation should have been failed before this stage.

static

Sets the value of a property based on the specified property value and GParamSpec.

Parameters

prop_value	A pointer to the GValue where the property value will be set.
param_spec	A pointer to the GParamSpec that describes the property.
property_value	A string representing the value to be set for the property.

Note: This API is intended to be used by gst_tensor_parse_config_file ()
