Description

A new sample accurate but somewhat slow FFmpeg based audio source filter for AviSynth+. No indexing required and only available in 64-bit.

Requirements


Syntax and Parameters

BestAudioSource (string "source", int "track", int "adjustdelay", bool "exactsamples", string "varprefix")


string  source =
Path to audio file. Path can be omitted if the script is in the same folder as the audio file.


int  track = -1
Positive track numbers refer to the FFmpeg given stream number. Negative numbers refer to the nth audio track with -1 being the first.


int  adjustdelay = -1
Delay adjustment; not yet implemented.


bool  exactsamples = false
Set to true if you want opening files to be really slow but for some reason need a completely sample exact length.


string  varprefix = ""
Works the same as FFMS2.
  • "BASCHANNEL_LAYOUT"
  • "BASVALID_BITS"


Examples

BestAudioSource("blah.mp4", track=-1, adjustdelay=-1, exactsamples=false, varprefix="")
