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 - Camera supports: - Sample applications - `gst-camera-single-stream-example`, which allows single camera streaming to display or video encoder, or network (RTSP). - `gst-multi-camera-example`, which allows concurrent streaming from two cameras. - `gst-multi-stream-example`, which allows single camera data duplicated into two streams using [tee](https://gstreamer.freedesktop.org/documentation/coreelements/tee.html). - `gst-snapshot-stream-example`, which allows snapshot generation along with active video recording. - `gst-activate-deactivate-streams-runtime-example`, which allows camera resolution modifications on-the-fly without sensor restart. - `gst-appsink-example`, which is an application of transformations and other algorithms to a camera frame before encoding. - `gst-camera-metadata-example`, which is a metadata such as scene mode, white balance, and bit rate. - Real-time camera up to 4K at 30 fps or 1080p at 60 fps - Multistreams directly from a single camera - Multiple camera access from single or multiple client applications - Multiple snapshot support (RAW/JPEG) at configurable resolutions - Common camera controls such as contrast, international organization for standardization (ISO), and white balance are using the GStreamer camera plugin properties. - Camera metadata for fine-grain control of camera configurations. - Video supports: - Sample applications - `gst-audio-video-encode`, which allows encoding of audio and video data, which is then stored into a user-specified output file. - `gst-concurrent-videoplay-composition`, which allows to playback multiple videos composed on a device. - `gst-videocodec-concurrent-playback`, which allows decoding and playback of multiple formats concurrently. - `gst-audio-video-playback`, which has audio and video playback capabilities. - `gst-video-transcode-example`, which allows video transcoding of AVC-to-HEVC or HEVC-to-AVC format. - `gst-video-playback-example`, which allows decoding and playback of a video file. - The file-based decode and playback feature - Video for Linux (V4L2)-based hardware encode and decode - 16 parallel instances for encode and decode - Encode supports: - Codecs: H.264, H.265 - Controls: Profile, level, bit rate control, minimum and maximum quantization parameter (QP), group of pictures (GOP), entropy coding, slice, Hier-P, rotation, flip, and long term reference (LTR) - Dynamic property control: LTR, bit rate, and flip - 4K30 + 720p30 encode - Decode supports: - Formats: NV12, TP10 Qualcomm universal bandwidth compression - Playback controls: Play, pause, resume, forward, and reverse - Dynamic resolution change - Video graphics array (VGA at 640 x 480) with 16 parallel instances - 720p with 8 parallel instances - 1080p with 4 parallel instances - UHD with 2 parallel instances - Audio supports: - Sample applications - `gst-audio-encode-example`, which allows audio recording. - `gst-audio-decode-example`, which allows playback of an audio file. - `gst-transform-example`, which has use cases where a video stream should be transformed (rotate, flip, and scale). - `gst-weston-composition-example`, which allows composition of various sources, specifically live camera input, and an offline file. - Hardware-accelerated audio capture and playback using pulse plugins - Graphics supports: - Hardware-accelerated plugins for compose, transform, and conversion - Composition: N input to 1 output. For example: video wall, ML metadata, and picture-in-picture - Transform: Crop, rotation, scale (down/up), color convert, and flip - Split: 1 input to N outputs based on user input region of interest (ROI) - AI/ML supports: - Sample applications - `gst-ai-classification`, which allows classification on a live camera stream. - `gst-ai-multi-input-output-object-detection`, which allows AI/ML inferencing on various input sources. - `gst-ai-object-detection`, which allows object detection on images streamed from a camera. - `gst-ai-parallel-inference`, which allows multiple AI/ML models running in parallel on a single live stream from a camera. - `gst-ai-pose-detection`, which allows pose detection on images streamed from a camera. - `gst-ai-segmentation`, which allows object segmentation on images streamed from a camera. - ML framework: LiteRT, Qualcomm Neural Processing SDK, and Qualcomm AI Engine direct SDK - Models: Classification, detection, pose estimation, and segmentation - Tensor-based input and output for fast processing - Submodule-based postprocessing for flexibility of adding support for new models - Overlay inference results on input frame for complete ML use case realization - Miscellaneous includes: - Containerization reference - Socket source and sink plugins that: - Enable zero copy data path between two separate processes running their own GStreamer pipeline - Separate processes/applications are either within the native layer or within the docker execution environment ## Sample applications Sample applications are classified into two categories, each tailored to specific use cases like retail, AI edge box, IP camera, drones, and robotics. - Multimedia applications: These focus on camera, video, audio, and graphics functionalities. - AI/ML applications: These primarily focus on AI and ML capabilities. For a 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). ## Limitations The following are the known limitations in the QIMP SDK release: - The FastCV engine of `qtimlvconverter` doesn’t support nonstandard resolution conversion. Use the OpenGL for embedded systems (GLES) engine as the convertor on this platform. - When using the `qtioverlay` plugin with detection models, frame drops may occur, especially with many detections. Use qtivcomposer for detection-based ML use cases. - Speed-based video playback isn’t supported in this release. - A drop of 1–2 fps may be observed with the three-stream camera use case.
