LSMASHVideoSource/LibavSMASHSource will/can result to worse performance compared to LWLibavVideoSource/LWLibavSource if it's used for anything than previewing. (#41)
If you have issues about the file names save the AviSynth script (.avs) as UTF-8 or just enable UTF-8 code pages in Windows (if available) - Windows Settings > Time & language > Language & region > Administrative language settings > Change system locale, and check Beta: Use Unicode UTF-8 for worldwide language support.
This is the recommended FFmpeg version.
