Following the release of Rasplex/OpenPHT 1.6.2 it is now possible to configure seek steps by adding to/creating an advancedsettings.xml file in /storage/.plexht/userdata with the following content:
<advancedsettings>
<videoseeksteps>-15,+30, etc</videoseeksteps>
<musicseeksteps>-15,+30, etc</musicseeksteps>
</advancedsettings>
The default values are:
videoseeksteps: -300,-180,-120,-60,-30,-15,+30,+60,+120,+180,+300
musicseeksteps: -60,-30,-15,+30,+60
