RV565: Cross-Layer Co-Design for Frame-Independent Video Playback on MicroPython-Class ESP32-S3 Systems

Video on SPI-attached microcontroller displays is limited less by decoding than by where each byte lives and which stages run serially. We present RV565, a decode framework for frame-independent video whose decoded representation is the panel's native RGB565 format, and evaluate it on an ESP32-S3 with two ten-second windows of an openly licensed film. A serial path - inflate, then scale into internal-memory stripes overlapped with SPI direct-memory-access (DMA) transfers - meets the 41.7 ms dea…
