Audio support on VapourSynth

Is it possible to support audio when using VapourSynth?

I actually just ran into a need for this myself, so +1'ing this request.

Why don't you use BestSource instead? https://github.com/vapoursynth/bestsource

I actually have in some instances, but the indexing speed of ffms2 + the ability to separately build an index using the ffmsindex CLI leads to a significant reduction in processing time for my workflow.

Most of my source files are FFV1 + FLAC MKVs, which are both huge (and can be very slow to index), but they also avoid a lot of the problems that H264/HEVC/etc sources have, which is where BestSource shines.

So the speed of ffms2 + working with "unproblematic" sources makes ffms2 a real boon.
