Building

Windows

• Build libAO for Windows, FFmpeg, Qt, and link it with Vrok. It is easier if you use qmake

Linux

• Build or install libAO, libasound, FFmpeg, Qt
• Build using qmake

Linux - with python support

• Build or install libAO, libasound, FFmpeg, Boost Python, Python
• Build using make

Android

• Make sure you have built FFmpeg for Android and fix the paths in Android.mk
• Build using ndk-build
• Note that the java application that is bundled has not been commited to this repo yet, whatever you build will have to have another interface or main application

Running

Windows & Linux

• VrokNext has a command line interface as of now, it supports cd and ls. If you want to change its start up directory input it as an argument to the application.
• To play a file enter its number(index).
• To change properties of plugins use below commands,
  1. setc - sets the current component that you want to make changes to (e.g. setc FIR filter:0)
  2. setp - sets properties of the current component (e.g. setp lp_freq 100, sets lp_freq to 100)

Supported Commands

<index> play the file with the given index
open <filename> play given file
openi i play file with the given index
p pause
r resume
ls similar to Unix ls, lists current directory's contents
cd <dir>|<dir index> similar to Unix cd, changes directory through text and index (shown in ls output)
setc <component name> sets current component
setp <property name> <property value> sets current component's properties

Currently implemented components and their properties

1. SSEQ (Shibatch Super EQ by Naoki Shibata)
   18 band equalizer that has following properties
   preamp = [0.0..inf), default: 1.0
   band_0 through band_17 = [0.0..inf), default: 1.0

2. FIR filter Despite the name, currently implements a bass enhancer (from Calf plugins for JACK)
   dry_vol = [0.0..inf), default: 1.0, dry signal mix level
   wet_vol = [0.0..inf), default: 1.0, wet signal mix level
   blend = [-10.0..10.0), default: 9.0
   drive = [0.0..10.0), default: 1.0
   lp_freq = [0.0..20000.0], default: 150.0, low pass frequency
   hp_freq = [0.0..20000.0], default: 50.0, high pass frequency

Linux - with python support

• Execute python3 testbp.py dir0 [dir1 [dir2 [dir3 [ ... [dirN]]]]] , dirX are directories that the script will search for media
