AviSynth (and plus) license

This question was probably asked and answered many times before, but I can't find them. As I understand, the original AviSynth is distributed under GPLv2. I do not find any license information of AviSynthPlus, but assuming it should also be GPLv2 due to copyleft. Here are my questions:
  • If a software redistributes AviSynth dll via installer without any modification, is it required to be also open sourced under GPLv2? For instance, svpflow1 is GPLv2 according to http://avisynth.nl/index.php/SVPflow.
  • If I develop a software (e.g. https://github.com/CrendKing/avisynth_filter) that utilizes AviSynth C/C++ API without any modification to AviSynth itself, and do not redistribute AviSynth, am I allowed to open source under licenses other than GPLv2?
