+#!/bin/bash
+# setup_hw_decode.sh — Enable Rockchip hardware video decoding on ArkOS / R36S
+#
+# What this script does:
+#   1. Adds a udev rule so the 'video' group can access /dev/vpu_service
+#      (the VPU device used by Rockchip MPP on the kernel 4.4 BSP).
+#   2. Tries to install librockchip-mpp0 and gstreamer1.0-rockchip-mpp.
+#      If they are not in apt, it prints instructions for manual installation.
+#
+# Requirements:
+#   - Must be run as root or via sudo.
+#   - Internet access (for apt-get).
+#   - Target: RK3326 / PX30 device running ArkOS with Ubuntu eoan arm64.
+#
+# After this script succeeds, restart the DLNA browser app.  The GStreamer
+# backend will detect mppvideodec and prefer it over software avdec_h264.

+# Sources known to carry arm64 builds for RK3326/PX30:
+#
+#   A) ODROID community apt mirror (requires adding the source manually):
+#      deb https://oph.mdrjr.net/meveric/ stretch main
+#      apt-key adv --keyserver keyserver.ubuntu.com --recv-keys A0A3B33F
+#
+#   B) Pre-built .deb files from the OGA / ArkOS forum / Discord.
+#      Typical package names:
+#        librockchip-mpp0_1.x.x_arm64.deb
+#        gstreamer1.0-rockchip-mpp_1.x.x_arm64.deb
+#
+#   C) Build from source (advanced):
+#        https://github.com/rockchip-linux/mpp
+#        https://github.com/JeffyCN/gst-mpp
+#
+# This script tries apt-get first; if the package is not found it falls back
+# to printing the manual instructions and exits with success (non-blocking).
