# Spawn script for tvheadend to transcode live TV in real-time using an Intel / vaapi hardware device.
# Create a new Profile in tvheadend called "pass", disable the built-in pass profile, and set this one as
# the default.
#
# This is specifically designed for UK DVB-T and DVB-S processing for Plex DVR. The script transcodes
# the incoming TV stream to 50hz video using field based deinterlacing. Plex enforces frame based
# deinterlacing at all times, so if you have a client that cannot direct play recordings reliably
# (e.g. Samsung and probably others) you will only be able to get 25hz "filmic" recordings. This
