dejavis-ui is a trivial Audio/Video mixer with VIS
I started this as a "swiss army knife" for audio/video form "any" source to "any" dest.
I also integrated the terrific projectM library to add fancy vis if needed
dejavis-ui is diveded in two parts backend and frontend.
backend is main app that run on machine and uses the gpu/cpu to do fancy stuff with your media
frontend is the webpages (react/TS) that connect via websocket and control the backend.
Since backend is controlled via websocket, anyone can write his own controller for backend in any language.
Features:
- Audio Mixer (16x2) Input can be live,url,file
- Video Mixer (Vulkan based) with integrated Post-Processing (ChromaKey,LumaKey) on RGB space (for now)
- High-performance YUV to RGB conversion (NV12, P010, UYVY, YUV420P)
- Support for static image sources
- projectM vis (openGL -> Vulkan zero-copy)
- projectm presets persistence via SQLite
- vulkan video decode and encode (if supported by hw/drivers (MacOS uses videotoolbox))
- SRT output
- SPOUT2 support (windows only)
- Web Interface for setting/controlling
- Win/Linux/Mac support
- NDI Support (both send and receive)
- WebRTC Video/Audio or only Audio (to remote monitor the output)
Since this is a "complex" software involving many process/protocols/codecs it uses many great library under the hood
