# 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). |
