amlogic_meson_dvb4linux

This repository is our prototype for distributing Linux DVB drivers for our demodulator products. Here, we have integrated our AVL62x1 S/S2/S2X demodulator driver and the Airoha AV201x tuner driver and our AVL68x2 multistandard demod driver and the R848 tuner driver into a DVB frontend devices for the Amlogic Meson SoC. We package the drivers into the CoreELEC distro as a proof of concept.

How to use with CoreELEC

The following will build CoreELEC with our drivers built into the "CrazyCat" driver set

cd
git clone https://github.com/availink/CoreELEC_avl.git CoreELEC
cd CoreELEC
git checkout HACKING_9.2.1
cd
git clone --recurse-submodules https://github.com/availink/amlogic_meson_dvb4linux.git
cd CoreELEC
