On the homepage for TVheadend there are conflicting information about the available parameters for the field »post-processor command«.
In the documentation here
http://docs.tvheadend.org/webui/config_dvr/
there is a parameter %s listed to hand over the program subtitle.
In the wiki here
https://tvheadend.org/projects/tvheadend/wiki/Tvheadend_post_recording_scripts
this parameter does not exist.
I tried to use »%s« for a script in TVH 4.0.9 as it is included in the builds for OSMC, but obviously the parameter does not work but instead literally passes »%s«. Other params like »%t« or »%f« do work as expected.
Does some other parameter to pass the subtitle exist?
