- Create socket outputs? - Visual outputs? * Take control of additional devices and spawning new demodulators (i.e. trunkers) * Script manager / live editor * Provide scriptable liquid-dsp modulation for trancievers? * Allow scripts to launch/run headless (no UI) - "PVR" like mode with waterfall time shifting - L/R and surround-sound balance settings for separating and listening to mono streams - Add tool for converting decimated I/Q recording to video - Select video features such as title/demodulation/scope/waterfall/etc - Render to video from GL frames->ffmpeg/mencoder /w demodulated audio - Accessability / Control - USB/MIDI control surfaces - Joystick / gamepad input - Vibration / force-feeback - Investigate compilation via emscripten using rtl_tcp for input - Create web server+rtl_tcp bundle for embedded devices - Use emscripten compiled CubicSDR via embedded web server Target Platforms: ---------------- - [x] OSX - [x] Windows - [x] Linux - [ ] HTML5 License: ------- - GPL
