Overview

qtimltflite is a GStreamer inference element that executes TensorFlow Lite models as part of AI and multimedia pipelines. The element operates entirely in tensor mode: it accepts input tensors on its sink pad and produces output tensors on its source pad according to the model’s input and output specifications. The element is limited to model execution. It does not perform preprocessing, tensor reshaping, batching, layout conversion, or model-specific post-processing. These functions are expected to be handled by adjacent elements in the pipeline. As a result, upstream elements must provide tensors that already match the model requirements, and downstream elements must interpret the output tensors produced by inference. qtimltflite supports multiple TensorFlow Lite execution backends through delegates, including CPU, GPU, and external delegate configurations. This allows the same pipeline structure to be deployed across different hardware targets and optimized for different performance, latency, and power requirements. The element is intended for real-time and embedded AI pipelines where inference is one stage in a larger modular processing flow.

Key Responsibilities

qtimltflite is responsible for:

Loading and executing a TensorFlow Lite model
Accepting preformatted input tensors from upstream elements
Producing output tensors that match the model output signature
Negotiating tensor data types and dimensions with adjacent elements
Propagating tensor metadata required by downstream elements

In practice, qtimltflite serves as the inference stage in the pipeline, while tensor preparation and result interpretation are handled externally.

Input and Output Behavior

Input Tensors

qtimltflite exposes a single sink pad, but it supports both single-input and multi-input models. For multi-input models, all required tensors are delivered through the same sink pad as a tensor set. Input tensors must be fully prepared before they reach qtimltflite. Expected tensor layout, shape, data type, and batch size are determined by:

the TensorFlow Lite model input signature
caps negotiation with upstream elements

Typical upstream elements include:

qtimlvconverter for scaling, color conversion, normalization, and quantization
qtibatch for batch construction

qtimltflite does not modify, reshape, batch, or reinterpret incoming tensors. It passes them to the TensorFlow Lite runtime as received.

Output Tensors

qtimltflite exposes a single source pad and produces output tensors according to the model output signature. The single source pad does not limit the element to a single tensor. Models with multiple output tensors are fully supported, and all outputs are emitted together on the same pad. The element supports:

single-output and multi-output models
arbitrary tensor ranks, including batch and depth dimensions
quantized and floating-point outputs

Output tensors are typically consumed by downstream post-processing elements, which decode model-specific results such as classification scores, detection boxes, segmentation masks, landmarks, or other structured outputs.

Quantization and Dequantization

qtimltflite can optionally dequantize quantized output tensors, such as UINT8 or INT8, into FLOAT32. This conversion uses the quantization parameters stored in the TensorFlow Lite model metadata.

Conditional Output Dequantization

Dequantization is performed only when the downstream path requires FLOAT32 tensors. In practice, this is enabled when downstream caps negotiation indicates that floating-point output is needed. When dequantization is applied, qtimltflite:

reads the tensor scale
reads the tensor zero_point
applies the standard TensorFlow Lite dequantization formula:

output_float = scale × (quantized_value - zero_point)

produces FLOAT32 tensors for downstream processing

When Dequantization Is Skipped

Dequantization is not performed when:

downstream elements accept only quantized tensor types
no downstream element negotiates FLOAT32
the model output tensor does not contain valid quantization metadata

In these cases, the output tensor is forwarded in its original quantized representation. This behavior allows the same downstream processing path to support both quantized and floating-point models where applicable, while avoiding unnecessary conversion.

Supported Data Types

qtimltflite supports the tensor data types provided by the TensorFlow Lite runtime and the selected execution backend, subject to caps negotiation with adjacent elements. Commonly used data types include:

UINT8
INT8
INT32
FLOAT16
FLOAT32

The element does not impose additional data-type restrictions beyond those required by the runtime, the selected delegate, and negotiated pipeline caps.

Batch and Depth Model Support

qtimltflite supports models with batch and multi-dimensional tensor inputs and outputs, including tensors with explicit batch and depth dimensions. Examples include:

batched tensors: N × H × W × C
multi-dimensional tensors: N × D × H × W × C

The element treats these dimensions transparently and passes tensors to TensorFlow Lite according to the negotiated shape. It does not construct batches, reshape tensors, or reinterpret tensor dimensions internally. Batch construction must be handled by upstream elements such as qtibatch. This behavior keeps inference predictable across single-frame, batched, and higher-dimensional workflows.

Delegates

A TensorFlow Lite delegate defines the execution backend used to run a model. Delegates allow qtimltflite to offload inference from the default TensorFlow Lite CPU interpreter to an optimized backend, such as GPU, an optimized CPU runtime, or NPU. qtimltflite supports multiple delegate options. The delegate is selected through the delegate property and controls how TensorFlow Lite dispatches model operations during inference.

Built-in Delegate Options

none

Runs the model on the default TensorFlow Lite CPU interpreter.

Backend: CPU
Use case: reference execution, debugging, or systems without acceleration

gpu

Runs supported operations through the TensorFlow Lite GPU delegate.

Backend: GPU
Use case: floating-point models/workloads that benefit from GPU parallelism

xnnpack

Runs inference through the XNNPACK optimized CPU backend.

Backend: Optimized CPU
Use case: improved CPU performance for supported floating-point and quantized models

External Delegate Support

External delegate is used to accelerate models on Qualcomm’s NPU. When an external delegate is selected, qtimltflite loads and configures the delegate at runtime using the following properties:

external-delegate-path
- Path to the external delegate shared library.
external-delegate-options
- Delegate-specific initialization options passed to the external delegate.

After initialization, supported model operations are offloaded to the NPU backend implemented by the external delegate.

Runtime Memory Behavior and GAP Handling

qtimltflite operates within the memory model of the TensorFlow Lite runtime. Although the surrounding pipeline may use zero-copy transport for tensor buffers, TensorFlow Lite execution requires input and output tensors to reside in runtime-managed memory.

TensorFlow Lite Memory Model

TensorFlow Lite uses an internal memory arena to allocate:

input tensors
intermediate activation tensors
output tensors

GAP Buffer Handling

qtimltflite is GAP-aware and correctly handles input buffers marked with GST_BUFFER_FLAG_GAP. When a GAP buffer is received, the element skips inference and forwards the buffer downstream. This preserves timing and synchronization while explicitly indicating that no valid inference input is available for that timestamp. GAP buffers commonly appear in conditional AI pipelines, such as cascaded workflows where later inference stages run only when earlier stages produce valid regions of interest.

Usage

Single-Stage AI Inference on Live Camera Stream

This example demonstrates real-time inference on a live camera stream using a single instance of qtimltflite. Inference results are attached to each GstBuffer as MLMeta, allowing downstream elements to access synchronized metadata directly from the frame. An overlay stage then uses this metadata to render annotations such as bounding boxes, labels, or key-points before display or further processing.

Two-Stage Daisy Chain AI Inference on Live Camera Stream

This example demonstrates a two-stage TensorFlow Lite inference workflow using two qtimltflite instances. The first model operates on full video frames after preprocessing by a qtimlvconverter configured for full-frame input. Inference results, such as detected objects, are attached to the corresponding video buffer and propagated downstream. The second model runs once for each object detected by the first stage. A second qtimlvconverter, configured for ROI-based processing, crops each detected region from the input frame and prepares it as input for the second qtimltflite instance.

Four-Stage Daisy Chain AI Inference on Live Camera Stream

The example demonstrates a multi-stage inference workflow for live Hand-Gesture recognition use case built with four TensorFlow Lite models executed through four qtimltflite instances.

Stage 1 performs full-frame palm detection. The input video frame is preprocessed, passed through inference, and post-processed to generate metadata describing the detected palm.
Stage 2 performs per-ROI hand landmark inference. Regions detected in the first stage are cropped and batched for processing. Two post-processing paths are used: one generates visualization metadata, while the other reformats the output tensors for the next stage.
Stage 3 chains two models in tensor-only mode, without additional preprocessing or post-processing. The first model consumes multiple tensors produced by the previous stage, and its output is passed directly to the second model.
Stage 4 performs final gesture classification and converts the model output into metadata for downstream use.
