## Contents of the release

The contents of the Qualcomm IM SDK release include:

- Recipes for building the individual components:

    - Qualcomm IM SDK
    - LiteRT
    - 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 Qualcomm IM SDK, see [Qualcomm Intelligent Multimedia (IM SDK) Quick Start Guide](https://docs.qualcomm.com/bundle/publicresource/topics/80-70014-51/introduction.html).

## New features

The following are the new features introduced in the Qualcomm IM SDK release:

- Camera supports:

    - Sample applications

        - `gst-add-streams-as-bundle-example`, which is a configuration of camera streams as a bundle, thus, saving on time.
        - `gst-camera-burst-capture-example`, which allows snapshot capture in the Burst mode.
        - `gst-camera-switch-example`, which allows to switch between two cameras.
        - `gst-add-remove-streams-runtime`, which allows the addition and removal of multiple streams dynamically.
    - Multiple streams with different framerate for each stream
    - USB camera using the v4l2src GStreamer plugin
    - Different video HDR modes: RAW linear SHDR (V2), YUV virtual channel SHDR (V3), and SHDR switch from linear to RAW linear SHDR (V2)
    - Electronic image stabilization (EIS) for preview only or preview + video use case
    - Reprocess to generate multiple streams from a single input stream based on configured region of interest (ROI) coordinates
    - Continuous JPEG snapshots at 30 fps along with preview
- Video supports:

    - Playback framerate control
- Graphics supports:

    - User configurable polygon privacy mask and inverse privacy mask using the gstqtioverlay plugin
- AI/ML supports:

    - Sample applications

        - `gst-ai-monodepth`, which allows monodepth on images streamed from a camera.
        - `gst-ai-daisychain-detection-classification`, which allows cascaded object detection and classification on images streamed from a camera.
    - Multistage ML pipeline (daisy chaining) for advanced ML use cases; for example, detection followed by classification based on detected objects.
    - Socket-based gstqtisocketsrc and gstqtisocketsink plugins to support efficient/zero copy data flow between pipelines running inside docker and host.
    - Hardware-accelerated gstqtivsplit plugin to support input image crop based on ML detection ROI output. This plugin generates a stream per detected ROI that’s used for multistage ML pipeline or other purposes like storage.
    - Concurrent AI pipelines without impacting the performance
    - Mono-depth estimation ML model (midas-v2) for depth estimation based on a single image

## Sample applications

For a list of sample applications supported in the Qualcomm IM SDK and instructions on how to run them, see [Sample applications](https://docs.qualcomm.com/bundle/publicresource/topics/80-70014-50/example-applications.html).

## Issues resolved

Fixed speed-based video playback.

## Limitations

The following are the known limitations in the Qualcomm IM SDK release:

- When using the `qtioverlay` plugin with detection models, frame drops may occur, especially with many detections. Use qtivcomposer for detection-based ML use cases.
- A drop of 1–2 fps may be observed with the three-stream camera use case.
