QCAP & QDEEP Software Development
Intelligent Video Applications for Capture, Recording, Streaming and Artificial Intelligence
Since YUAN entered the video capture card industry, they’ve refined their ‘QCAP’ SDK for customers worldwide. Their expanding range of video capture cards enhances the QCAP SDK’s functionality, evolving from basic video capture and driver integration to include diverse streaming protocols, storage formats, and video effects. To address emerging needs in Artificial Intelligence, YUAN launched the AI QDEEP SDK in 2017. This SDK incorporates various algorithms and deep-learning models for applications such as image content analysis, biometric analysis, and human behavior analysis.
SDK
Yuan’s advanced video capture cards feature multiple interfaces for raw data capture, which is analysed by QDEEP for processing, editing, streaming, and recording through QCAP. Their SDK allows users to quickly create applications with essential features, with ongoing focus from their engineering team on integrating the latest technology into QCAP.
QCAP SDK provides a comprehensive suite of functions for video capture cards, seamlessly integrates capabilities for recording and streaming, and offers robust cross-platform features that enhance its usability across different systems.

Platforms
Yuan focuses on testing with the latest hardware platforms for optimal compatibility, unbiased towards any particular OEM. The QDEEP SDK supports various operating systems, allowing users to maintain past developments and ensure flexibility in future hardware planning. In essence, development with QDEEP is completely transferrable.
Applications
The QDEEP and QCAP SDK’s serve the same purpose; to reduce difficulties developers may find during integration, as well as interchanging results of development between different platforms – for example, from embedded platforms such as nVidia GPU, nVidia Jetson or Intel OpenVINO etc. In short, Yuan’s SDK’s can save developers the (often) long gestation periods needed to fine tune the minor differences between platforms and shorten the overall development process.
Capture Features
Yuan’s capture cards are capable of snapshotting video in various ways including single, continuous, cropping and scaling. As to the capture snapshot format, video can be saved in BMP, JPEG, PNG and TIF formats.
Yuan’s capture engine offers advanced features such as de-interlacing and an alpha blending engine, which together enhance the user’s ability to seamlessly integrate snapshots with text and modify color schemes among other adjustments. This allows for a more dynamic and visually appealing presentation, making it easier to create customized visuals for a variety of projects.
Recording
Yuan’s SDK records input video in several major codec formats which include MPG2, H264, H265, RAW. Regarding audio, the SDK supports AAC. Yuan can also integrate several mainstream SDK’s into their SDK to allow developers to take advantage via different hardware – which covers Intel, AMD and nVIDIA platforms.
Within the recording SDK there is a transitional effect feature which allows modification for the recording – such as scaling, rotation, alpha blending, and action script. There is also a PGM function to allow professional providers to share & overlay their videos with ease.
Streaming
The QCAP SDK can support various streaming protocols inclusive of HLS, RTSP, TS, and RTMP. QCAP will also allow integration of Onvif, WebRTC, and NDI for streaming. Streaming of 2D and 3D video is also an available application with the provision of an audio mixer when streaming and recording.
Editing
The editing feature provides user file export / manage & A/V stream read and write function within the SDK. It also integrates the Intel Media SDK for file transcoding. The SDK also provides a special feature for users to repair MP4 files if minor damage occurs.
Playback
For playback, Yuan’s SDK integrates many features from capture inclusive of all supported mainstream SDK’s. The SDK provides for all commonly used player features – including play, pause and speed control (forward / rewind) frame by frame.
Supported SDK Architectures
SDK supported programming languages : VC++ / C# / .NET / VB / Delphi / QT
SDK supported operating system platforms : Linux , Embedded Linux, Microsoft Windows.
