# 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).
