[Cross-platform]

Video Capture SDK .Net

v15.9
Our .Net SDK seamlessly integrates video capture and processing capabilities into software applications. This versatile SDK facilitates video and audio playback and supports capture from various sources, including USB webcams, IP cameras, Blackmagic Decklink cards, and camcorders. It provides comprehensive support for different output formats, including MP4, WebM, AVI, WMV, MPEG-1/2, and others. It also provides developers an extensive library of video and audio effects to enhance and customize multimedia content.

In addition, our SDK offers robust cross-platform compatibility, ensuring seamless integration with Windows, Linux, macOS, iOS, and Android environments. This cross-platform adaptability enables developers to create applications that work consistently across various operating systems and devices, providing users with a consistent and flexible multimedia experience.

SDK STRUCTURE

The SDK is highly compatible with more than 10 video and audio input sources and supports more than 20 output formats. It offers developers flexibility by accommodating a broad range of hardware options for input and output configurations. The SDK processes both video and audio content, enabling the saving of processed data to files or streaming it over network connections.

VIDEO CAPTURE PIPELINE

During the preview or capture stages, video and audio streams can be processed with various effects. Afterward, these streams are split and directed to encoders and audio/video renderers for further processing.

OUTPUT FORMATS

The SDK supports a wide range of popular video, audio, and image formats and codecs, such as MP4 (using H264/HEVC for video and AAC for audio), WebM (using VP8/VP9/AV1 for video and Vorbis or OPUS for audio), as well as WMV, MP3, JPEG, GIF, and PNG.

VIDEO PROCESSING

You can add text, images, or GIF logos, adjust brightness, contrast, saturation, or hue, resize, crop, or rotate content, and apply chroma-keying or various video effects to enhance your content.

AUDIO PROCESSING

Incorporate an equalizer into your application, allowing users to fine-tune their audio experience. This feature allows them to adjust specific audio frequencies, such as treble, midrange, and bass, to achieve their desired sound profile. Additionally, users can normalize audio levels or amplify volume, providing precise control over the audio output. Many other audio effects are also at their disposal for further customization.
