#!/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. Installs librockchip-mpp and the gst-mpp GStreamer plugin, in order:
# a) If a 'mpp-libs/' subdirectory is present next to this script,
# copies the pre-built .so files directly (no network required).
# b) Otherwise tries apt-get.
# c) If apt fails, prints manual installation instructions.
#
# 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.

# These packages are NOT in the standard Ubuntu eoan repos.
# 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).
