To get started with the QIMP SDK, see [Qualcomm Intelligent Multimedia Product (QIMP) SDK Quick Start Guide](https://docs.qualcomm.com/bundle/publicresource/topics/80-70018-51/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 Qualcomm Neural Network models. - Container supports application deployment using an API-based approach–GSTD. ## Sample applications | Sample application | Description | Supported SoCs | | --- | --- | --- | | **AI/ML applications** | **AI/ML applications** | **AI/ML applications** | | `gst-ai-face-detection` | Collects the live video input from a camera, file, or an RTSP stream and uses the Qualcomm Neural Network face detection model to produce a preview with the overlaid AI model output on the HDMI display. | QCS6490, QCS9075, and QCS8275 | | `gst-ai-face-recognition` | Collects the live video input from a camera or an RTSP stream and shares this input for face detection and recognition. | QCS6490, QCS9075, and QCS8275 | | **Video application** | **Video application** | **Video application** | | `gst-ai-smartcodec-example` | Reduces the network bandwidth or storage for input feed from a camera or file source. | QCS6490, QCS9075, and QCS8275 | For the complete list of sample applications supported in the QIMP SDK and instructions on how to run them, see [Sample applications](https://docs.qualcomm.com/bundle/publicresource/topics/80-70018-50/example-applications.html). ## Python sample applications | Sample application | Description | Supported SoCs | | --- | --- | --- | | **AI/ML applications** | **AI/ML applications** | **AI/ML applications** | | `gst-parallel-inference.py` | Supports multiple AI/ML models run in parallel (object detection, classification, segmentation, and pose detection) on streams from a camera, file source, or RTSP. | QCS6490, QCS9075, and QCS8275 | | `gst-daisychain-detection-pose.py` | Collects the live video input from a camera or an RTSP stream and shares this input for face detection and recognition. | QCS6490, QCS9075, and QCS8275 | | **Video application** | **Video application** | **Video application** | | `gst-concurrent-videoplay-composition.py` | Allows concurrent video playback for MP4 AVC (H.264) videos and performs composition on a video wall display. | QCS6490, QCS9075, and QCS8275 | | **Camera application** | **Camera application** | **Camera application** | | `gst-multi-camera-stream-example.py` | Enables you to stream from two camera sensors simultaneously. | QCS6490 | For the complete list of Python sample applications supported in the QIMP SDK and instructions on how to run them, see [Python applications](https://docs.qualcomm.com/bundle/publicresource/topics/80-70018-50/python-sample-applications.html). ## Issues resolved The following issues are resolved in the QIMP SDK release: - 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. **Workaround**: 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 use cases with DLC models. - Frame drops are observed with the Qualcomm Neural Network plugin while running on GPU delegate. - Low FPS with daisychain detection and pose GStreamer pipeline. - Stability issues are observed with GStreamer pipeline in batched model use cases. - High inference time is observed with `deeplabv3_resnet50.dlc`. - Concurrent streams with smart codec functionality encounter pipeline stalls and cleanup errors at the end of the stream. - Pose estimation for the `facemap_3dmm_quantized.bin` (Qualcomm Neural Network) AI hub model doesn’t work with Qualcomm IM SDK pipeline due to caps mismatch. - Caps mismatch with the AI hub face detection Qualcomm Neural Network model. - The `gst-ai-parallel-inference` sample application hangs for QCS8275. - Support for the FastCV engine is disabled in `qtivtransform`.
