Note about LSMASHVideoSource and LibavSMASHSource

LSMASHVideoSource/LibavSMASHSource will/can result to worse performance compared to LWLibavVideoSource/LWLibavSource if it's used for anything than previewing. (#41)

Note about the file names (Windows only)

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.

Note about decoding audio and video from the same file in the same script

Always prefer this order

audio = LWLibavAudioSource()
video = LWLibavVideoSource()

over this order

video = LWLibavVideoSource()
audio = LWLibavAudioSource()

In the second case the file will be scanned twice and the video info will be written twice (overwritted) in the index file.

FFmpeg

This is the recommended FFmpeg version.
