Hi to all! Maybe it will be interesting for you! I've made a script patching synocodectool and adding codec pack for Advanced Media Extentions for DSM 7.1.1 As a bonus I've included CH341 drivers (for me it's zigbee stick support). This script is not my workaround but a little help to include much information in one place. If it's interesting for your community, you're welcome! If not, admin please purge my message =)
1.) wget https://derbunov.ru/dsm_7.1.1_patch.tar.gz
2.) tar -xvf dsm_7.1.1_patch.tar.gz
3.) cd dsm_7.1.1_patch
4.) sudo ./start.sh
For patching synocodectool you need to choose 1st item then the item depending on you app and again until complete.
Zigbee drivers are tested with DENVERTON platform only!
