Simdify Video Plus Module

Simdify Video+ Module

Lights! Camera! Action!

Do you need to seamlessly process live streams or prerecorded videos, and see the results unfold in real-time? Writing shaders that run on video can be a little difficult. Part of what makes this module wonderful is that it makes it almost trivial to write shaders for video, using live video streams from RTSP sources, or prerecorded video. Another feature that makes this module wonderful is that video support can be exported to the Raspberry Pi 3/4 or other Linux devices. This module handles the fine details so you can focus on bringing your technical vision to life.

Supports Common Video Formats

YUV420P, NV12, YU12, and YUYV are common video pixel formats used in digital video processing. The clean, modern GLSL back-end seamlessly processes video in all these formats, and this module includes all the source code.

Compute Shader Compatible

If you use the Simdify Compute Module, you’ll be able to process video using compute shaders. This is the fastest way in the known universe to process video.

Exportable

You can export a video shader to Raspberry Pi 3/4 and many Linux platforms as well. That means you can write and debug the video processing shader on your PC and export a complete application compiles on your Raspberry Pi and uses its GPU to process video.

System Requirements

OpenGL 4.0 was released in 2010 — which means you don’t need the latest and greatest hardware to use Simdify! Simdify applications will attempt to use the most recent version of OpenGL on your device. The available OpenGL version determines which GLSL shading language version is available. The GLSL shading language version, along with the extensions supported by the OpenGL implementation that is active on your device, determine the complete set of features and capabilities available to you. Note that OpenGL support on any particular device may be incomplete, despite vendor marketing materials. For this reason, you can use Simdify Free Edition to precisely determine the features and capabilities of your graphics hardware. In general, minimum recommended system requirements for Simdify Video Plus Module are as follows.

OS

Windows 10, 11. May work on older versions of Windows, but Simdify is only supported on Windows 10/11.

MINIMUM CPU

Intel/AMD, 1 Physical Core, 4 Logical Processors

MINIMUM CPU RAM

8GB

MINIMUM GPU

Nvidia, AMD, or Intel GPU with support for OpenGL 3.0 and GLSL 130 or higher to use usampler. GLSL 420 or higher required to use image samplers such as uimage, and image load/store operations. If you do not have GLSL 420 or higher, your GPU may still support image load/store operations if the extensions described below are resident on your device.

MINIMUM GPU RAM

4GB

OPENGL EXTENSIONS

GL_ARB_shader_image_load_store, or GL_EXT_image_load_store, or similar to use image/uimage/iimage samplers and formats.

SIMDIFY MODULES

By default, video processing is handled by fragment shaders. Simdify Compute Plus Module is required to process video with compute shaders.

VIDEO DATA

Video files in .MP4 format if you wish to process pre-recorded video. A video camera capable of providing an RTSP address if you wish to process live video streams.
