The hardest part I find currently is matching a ssd_wv with correct version of inpustream.

Some versions of LibreELEC (ie. my test builds) include /usr/lib/libssd_wv.so, and a built-in (and matched) version of inputstream.adaptive, and in this case the helper would just need to create a libssd_wv.so symbolic link in DECRYPTERPATH with /usr/lib/libssd_wv.so as the target.

ie.

Code:

rpi22:~/.kodi/cdm # ls -la
total 16348
drwxr-xr-x    3 root     root          4096 Aug 24 00:32 .
drwxr-xr-x   13 root     root          4096 Aug 24 00:28 ..
lrwxrwxrwx    1 root     root            21 Jun 30 01:01 libssd_wv.so -> /usr/lib/libssd_wv.so
-rwxr-xr-x    1 root     root       5122508 Jul  5 14:06 libwidevinecdm.so

Official LibreELEC releases will (eventually) offer inputstream.adaptive as an installable addon and this addon will include lib/libssd_wv.so, avoiding any matching issues.

In both cases there should be no need for the helper to download libssd_wv.so, it would just need to create the symbolic link.

Pseudo-code for the helper:

Code:

if [ -f /usr/lib/libssd_wv.so ]; then
  ln -s /usr/lib/libssd_wv.so ${DECRYPTERPATH}/libssd_wv.so
elif [ -f ${HOME}/.kodi/addons/inputstream.adaptive/lib/libssd_wv.so ]; then
  ln -s ${HOME}/.kodi/addons/inputstream.adaptive/lib/libssd_wv.so ${DECRYPTERPATH}/libssd_wv.so
else
  # download/install libssd_wv.so from the internet etc.
