    SwiftShader

    SwiftShader

    SwiftShader is a high-performance CPU-based implementation

    SwiftShader is Google’s high-performance CPU-based implementation of the Vulkan 1.3 graphics API, designed to provide a hardware-independent rendering solution for 3D graphics. Unlike traditional GPU drivers, SwiftShader executes graphics commands entirely on the CPU, making it ideal for environments where dedicated graphics hardware is unavailable or unsuitable. It acts as a drop-in replacement for Vulkan drivers, allowing existing applications to run seamlessly by redirecting API calls through its software-based rendering engine. ...

    mpv

    mpv

    Command line video player

    ...There is a large selection of user scripts on the wiki. While mpv strives for minimalism and provides no real GUI, it has a small controller on top of the video for basic control. mpv has an OpenGL, Vulkan, and D3D11 based video output that is capable of many features loved by videophiles, such as video scaling with popular high quality algorithms, color management, frame timing, interpolation, HDR, and more. mpv can leverage most hardware decoding APIs on all platforms. Hardware decoding can be enabled at runtime on demand. A straightforward C API was designed from the ground up to make mpv usable as a library and facilitate easy integration into other applications. mpv is under active development, focusing on code refactoring and cleanups.

    CAVA

    CAVA

    Cross-platform Audio Visualizer

    Turn your phone or tablet into a fantastic audio viewer. Easy to use and customize. Choose from several preset settings of incredible colors or create your own. CAVA is a bar spectrum audio viewer based on my own open source project with the same name. Take the audio from the device's microphone and visualize the amplitude of the different frequencies as bars on the screen. Each bar represents a certain bandwidth of low to high frequencies. The leftmost bar starts at 50 Hz and the rightmost bar ends at 10 kHz. Although the frequencies outside this spectrum are audible, they do not contribute much to the overall sound image. ...
