## Contents of the release

The contents of the Qualcomm^®^ Intelligent Multimedia Product (QIMP) SDK
                release include:
- Recipes for building the individual components:
    - Qualcomm^®^ Intelligent Multimedia SDK (IM SDK)
    - Lite Runtime (LiteRT)
Note: LiteRT was formerly
                                    known as TensorFlow Lite.
    - Qualcomm^®^ Neural Processing SDK
    - Qualcomm^®^ AI Engine direct SDK
- Sample applications that demonstrate how to use the Qualcomm IM SDK to
                        develop AI edge-based applications.

To get started with the QIMP SDK, see [Qualcomm Intelligent Multimedia Product (QIMP)
                    SDK Quick Start Guide](https://docs.qualcomm.com/bundle/publicresource/topics/80-70017-51/introduction.html).

## New features

The following new features applicable to QCS6490, QCS9075, and QCS8275 are introduced
                in the QIMP SDK release:
- AI/ML supports execution of batched Qualcomm Neural Processing SDK models
                        and batched QNN models.
- Container supports application deployment using an API-based approach –
                        GStreamer daemon (GSTD).

## Issues resolved

- 18 FPS is observed with `gst-ai-parallel-inference` for file
                    source.
- `gst-ai-parallel-inference` hangs and black screen is observed at
                    EOS for RTSP source.
- RTSP sink streaming fails to play when you use multiple sinks such as RTSP, file
                    sink, and display with two or more input streams in
                        `multi-input-output-object-detection`.
- `gst-ai-monodepth` and `gst-ai-parallel-inference`
                    fails on QCS9075.

## Limitations

The following are the known limitations in the QIMP SDK release:
- When using the `qtioverlay` plugin with detection models,
                        frame drops may occur, especially with many detections. 
    **Solution**:
                            Use `qtivcomposer` for detection-based ML use
                        cases.
- A drop of 1–2 FPS may be observed with the three-stream camera use
                        case.
- AI/ML parallel inference for 24 streams varies between 25–30 FPS, which
                        is less than the expected 30 FPS.
- Segfault occurs while using Ctrl + C for Qualcomm
                        Neural Processing SDK use cases with DLC models.
- Frame drops are observed with the QNN plugin while running on GPU
                        delegate.
- Low FPS with daisychain detection and pose GStreamer pipeline.
- Observe stability issues with gstreamer pipeline in batched model
                        usecases.
- High inference time is seen with
                        `deeplabv3_resnet50.dlc`.
- Concurrent streams with smart codec functionality encounter pipeline stalls
                        and cleanup errors at EOS.
- Pose estimation for the `facemap_3dmm_quantized.bin` (QNN) AI
                        hub model does not work with the Qualcomm IM SDK pipeline due to caps
                        mismatch.
- Caps mismatch with the AI hub face detection QNN model.
- The `gst-ai-parallel-inference` sample application hangs for
                        QCS8275.
- Support for the FastCV engine is disabled in
                        `qtivtransform`.
