Купить дорого или выжать максимум из китайского проектора HY-300 через ADB и реверс-инжиниринг прошивки
Купил портативный проектор HY-300 — оказался не самым "ярким" представителем. Через ADB и root добрался до прошивки, нашёл скрипт testgamma, который при каждой загрузке занижает яркость до 70%. Разобрался как работает gamma LUT в видеопроцессоре VOP, какие параметры реально влияют на картинку, а какие — пустышки. Пошаговая инструкция по выжиманию максимума из проектора.

Rockchip RK3538 TV Box SoC and RK3572 mid-range HMI processor are coming soon

While we are eagerly waiting for the RK3668 and RK3688 high-end processors, Rockchip is planning to launch two mid-range SoCs with the RK3538 quad-core Cortex-A55 processor designed for TV boxes, and the RK3572 hexa-core Cortex-A73/A53 SoC for HMI (Human Machine Interface) applications.

Thanks to @Collabora's engineering, the RK3588/RK3576 video decoders are now mainline in Linux.
This is what open source collaboration is all about.

Come see it live on our ArmSoM Sige5 (RK3576) at the Collabora booth at #2026EmbeddedWorld!
Rockchip RK3588 and RK3576 H.264 and H.265 video decoders gain mainline Linux support

VDPU381 and VDPU383 video decoders are found in Rockchip RK3588 and RK3576 SoCs and variants like the RK3588S and RK3576J. So far, we had to rely on the Rockchip BSP to support hardware video decoding, but Collabora has just announced upstream/mainline Linux support for H.264 (AVC) and H.265 (HEVC) video decoding for RK3588 and RK3576 SoCs. Highlights of H.265/H.264 video decoder implementation on mainline Linux: A 17-patch series adding decoder support, in addition to dt-bindings and device tree nodes New V4L2 HEVC UAPI controls for explicit short-term and long-term RPS (Reference Picture Set) handling Fixing a non-obvious IOMMU restore issue caused by decoder-embedded IOMMU resets Struct-based register programming model to enforce completeness, ordering, and future multi-core readiness The new V4L2 UAPI controls for HEVC long and short-term Reference Picture Set (RPS) are required for the VDPU381 (RK3588) and VDP383 (RK3576) video decoders, contrary to some other decoders (e.g., VeriSilicon) that
Big news for Rockchip users: Upstream Linux now supports VDPU381 and VDPU383 hardware decode! This brings mainline H.264/HEVC acceleration, improved IOMMU-reset recovery, and new HEVC V4L2 controls that work with Vulkan Video! 🚀
