To get started with the Qualcomm IM SDK, see [Qualcomm Intelligent Multimedia (IM SDK) Quick Start Guide](https://docs.qualcomm.com/bundle/publicresource/topics/80-70020-51/qmi-sdk-qsg-landing-page.html). ## New features The following new features applicable to QCS6490, Dragonwing IQ-9075, and Dragonwing IQ-8275 are introduced in the Qualcomm IM SDK release: - AI/ML supports: - People counting in both people-analytics and region-analytics, which provides improved insights into occupancy and movement. - The `qtimlmetaextractor` plugin, which extracts and provides serialized machine learning metadata from the buffer for downstream processing. - AI box supports daisy chain up to 32 streams. - Video supports the real-time messaging protocol (RTMP), which enables real-time video streaming to compatible platforms. ## Sample applications For the complete 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/80-70020-50/example-applications.html). ## Issues resolved The following issues are resolved in the Qualcomm IM SDK release: - The `gst-ai-parallel-inference` sample application hangs on Dragonwing IQ-8275. - Support for GStreamer daemon (GStd), NV12 universal band width compression (UBWC) compressed streams, and sample applications dependent on NV12 UBWC isn’t enabled inside the docker. ## 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. **Workaround**: Use `qtivcomposer` for detection-based ML use cases. - AI/ML parallel inference for 32 streams varies between 20–30 fps depending on the model and input stream, 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 is observed with GStreamer pipelines for daisychain and pose detection. - 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 at the end of the stream. - Reverse playback is limited to video streams with a GOP length that fits within the buffer limitations of the video driver (<= 26). - For Dragonwing IQ-9075 and Dragonwing IQ-8275: > > > - Random corruption is observed at the beginning of playback for low-resolution (480p) NV12 UBWC compressed streams. > - A hang is observed while running use cases with batched models using GStreamer. - For QCS6490: > > > - Performance drops in superresolution end-to-end use cases due to post-processing issues affecting GPU stability. - The `waylandsink` plugin doesn’t support displaying windows at custom screen coordinates. - Starting from Qualcomm Neural Processing SDK version 2.34, LiteRT models encounter failure when executed with the benchmark\_model application using the Qualcomm Neural Network external delegate. - While running the `gst-daisychain-detection-pose` sample application, the output doesn’t display pose information within the extracted ROI regions. - Support for opencv isn’t enabled inside the Qualcomm IM SDK docker container. - The following applications have stability issues due to bugs in the application: - `gst-camera-three-stream-encode-file-detection-display-classification-rtsp.py` - `gst-camera-two-stream-detection-and-classification-side-by-side.py` - Playback of files with dynamic resolution change (DRC) may fail when the final resolution switch is to 4K or 480p. This issue is caused due to the mismatch between the buffer sizes allocated by the application and those expected by the driver. - Use cases involving the `qtismartvencbin` plugin fail due to a missing versioned library. ## Related documents - [Qualcomm Intelligent Multimedia SDK (IM SDK) Reference](https://docs.qualcomm.com/bundle/publicresource/topics/80-70020-50/qimsdk_landing_page.html) - [Qualcomm Intelligent Multimedia (IM SDK) Quick Start Guide](https://docs.qualcomm.com/bundle/publicresource/topics/80-70020-51/qmi-sdk-qsg-landing-page.html) - [Qualcomm Dragonwing RB3 Gen 2 Development Kit Guide](https://docs.qualcomm.com/bundle/publicresource/topics/80-70020-251/landing-page.html) - [Qualcomm Dragonwing IQ-9075 Evaluation Kit user guide – Linux](https://docs.qualcomm.com/bundle/publicresource/topics/80-70020-261/iq9-ug-update-the-sw.html) - [Qualcomm Linux Build Guide](https://docs.qualcomm.com/bundle/publicresource/topics/80-70020-254/build_landing_page.html) Last Published: Oct 15, 2025 [Previous Topic Qualcomm IM SDK release 1.6](https://docs.qualcomm.com/bundle/publicresource/80-70022-52/topics/qim-sdk-release-1-6.md) [Next Topic Qualcomm IM SDK release 1.4](https://docs.qualcomm.com/bundle/publicresource/80-70022-52/topics/qim-sdk-release-1-4.md)
