The python Bestsource helper

The audio support in vapoursynth has always been a piece of puzzle with headache to compile plugins on linux . Till now was based on bestaudio plugin and lsmas. The new comer bestsource changes the horizon but its integration and doc are not clear.

Motivations

I just needed to be able to trim videos with audio with vapoursynth avoiding to encode video with ffmpeg. This topic is not new and started far far ago on Doom9 forums.

vapoursynth plugins on linux

I recommend to use script hybrid vapourynth addon from Selur to compile lsmas, bestsource, wwxd. A big talk on porting vapoursynth plugins on linux can be found here

Installation

It requires a working vepoursynth env, and at least version 1.6.0 of peagisub for vapoursynth plugins path configuration.

I use scite , a lightweight editor to trigger vspreview by pressing [F5] (or compile) after adding the /etc/scite/vapoursynth.properties
