Is there a how to for compiling builds with working ddbridge?
I always compile the dddvb drivers myself for LibreElec and/or OpenElec.
I then load the drivers using the autostart.sh script of Kodi (or one could use the method as described in /storage/.config/modules-load.d/README I guess - never done that though).
Recently I added the instructions on how to do this on my site here:
Projects: Miscellaneous
or download it directly here:
dockerelec.tar.gz
Note that the LibreElec kernel must be compiled before you can build the dddvb drivers. So first build LibreElec and then the dddvb driver.
