# Qualcomm IM SDK release 2.0 ## SoC platforms and reference kits Table : Supported platforms and reference kits | SoC platforms | Reference kits | | --- | --- | | QCS6490 | | | QCS5430 | | | Qualcomm Dragonwing^TM^ IQ-9075 | | | Qualcomm Dragonwing^TM^ IQ-8275 | Qualcomm Dragonwing^TM^ IQ-8275 Beta Evaluation Kit (EVK) | ## Contents of the release The contents of the Qualcomm IM SDK release include: - Recipes for building the individual components: - Qualcomm^®^ Intelligent Multimedia SDK (IM SDK) - Lite Runtime (LiteRT) - Qualcomm^®^ Neural Processing SDK - Qualcomm^®^ AI Engine direct SDK To get started with the Qualcomm IM SDK, see [Qualcomm Intelligent Multimedia (IM SDK) Quick Start Guide](https://docs.qualcomm.com/doc/80-80020-51). ## Limitations The following are the known limitations in the Qualcomm IM SDK release: - 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. - Frame drops are observed with the Qualcomm^®^ Neural Network plugin when running on GPU delegate. - Frame drops are observed in daisychain detection‑pose usecases when the pose detection load (people per frame × model inference time) exceeds the per‑frame time limit (33 ms for 30 fps). - 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. > - Stability issues are observed when running multibatch ML use cases. - The `waylandsink` plugin doesn’t support displaying windows at custom screen coordinates. - When using the `qtimlpostprocess` plugin for postprocessing, a display latency occurs after approximately 30 minutes of running ML use cases on a camera stream. - Use cases with files having dynamic resolution change (DRC) may fail. This issue occurs because the video driver allocates buffers that are only partially accessible to the GPU driver. - `qtiobjtracker` exhibits non‑linear execution‑time growth during extended runs, which can act as a performance bottleneck. - ROI isn’t being generated in daisychain detection‑classification use cases when using a USB camera source with the YUY2 format. - The `qtiqmmfsrc` and `qtimltflite` plugins aren’t enabled in this release. - The Qualcomm IM SDK in a docker container isn’t supported in this release. Note To enable the `v4l2h264dec` and `v4l2h264enc` plugins, switch to the upstream video driver. For more information, see [GStreamer command-line use cases](https://docs.qualcomm.com/doc/80-80020-50/topic/gstreamer-application-use-cases.html). Note The following plugins are deprecated. Use the corresponding replacement plugins. | Deprecated plugins | Replacement plugins | | --- | --- | | `qtioverlay` | `qtivoverlay` | | | `qtimlpostprocess` | ## Related documents - [Qualcomm Intelligent Multimedia SDK (IM SDK) Reference](https://docs.qualcomm.com/doc/80-80020-50/topic/qimsdk_landing_page.html) - [Qualcomm Intelligent Multimedia (IM SDK) Quick Start Guide](https://docs.qualcomm.com/doc/80-80020-51/topic/qmi-sdk-qsg-landing-page.html) - [Qualcomm Dragonwing RB3 Gen 2 Development Kit Guide](https://docs.qualcomm.com/doc/80-80020-251/topic/landing-page.html) - [Qualcomm Dragonwing IQ-9075 Evaluation Kit user guide – Linux](https://docs.qualcomm.com/doc/80-80020-261/topic/iq9-ug-landing-page.html) - [Qualcomm Linux Build Guide](https://docs.qualcomm.com/doc/80-80020-254/topic/build_landing_page.html) - [Qualcomm Linux Migration Guide](https://docs.qualcomm.com/doc/80-80020-150/topic/landing-page.html) Last Published: May 14, 2026 [Previous Topic Qualcomm IM SDK release 2.0 RC2](https://docs.qualcomm.com/bundle/publicresource/80-80022-52/topics/qim-sdk-release-2-0-rc2.md) [Next Topic Qualcomm IM SDK release 1.7](https://docs.qualcomm.com/bundle/publicresource/80-80022-52/topics/qim-sdk-release-1-7.md)
