HW Transcoding not working anymore (Synology Diskstation)

[ChuckPa]

There is a known problem with the Intel iHD_drv_video.so file on Intel ApolloLake CPUs.

The temporary work around (while we fix it ourselves) is to delete it.

Anyone wishing to delete from the Synology command line can:

1. Sign in
2. sudo sh

Adapt the procedure below & substitute the rm command above for the shown script contents.
