WayDisplay

# WayDisplay I tried to get Linux running natively on a Blackview Tab 80 ([that didn't go well](/blog/bvtab80lin/)). What survived the attempt was the idea of using the tablet as a screen. WayDisplay turns it into a permanent sixth Hyprland monitor, at its native landscape resolution of 1280x800@60. Hyprland renders to a headless output. WayVNC captures that output and encodes it to H.264 on the AMD GPU's VA-API encoder, using a patched NeatVNC and WayVNC that speak the published (and rarely implemented) Open H.264 RFB encoding, number 50. The stream crosses to the tablet over a USB-only ADB reverse tunnel, so there's no network hop and no Wi-Fi involved. On the Android side, MediaCodec decodes the H.264 straight into a SurfaceView. On the current Tab 80 path, under sustained motion, p95 frame age is around 33.5ms, p95 time from source to decoder queue is around 22ms, and the stream sits around 5.2 Mbit/s. An earlier Samsung phone prototype, not the Tab 80 or its current transport.…
