Yasap is a simple command line audio player, that uses FFmpeg and SDL2 libraries, with support for multiple tracks in a single audio file trough Cuesheets embedded in a "cuesheet" named metadata tag (Vorbis comment, Matroska tag, MP3 tag, etc).
Written in C++14, in a Linux Debian stable (stretch) platform, should be easily portable in others fairly recently Linux/Unix platforms.
The code is in a unique C++14 source file (yasap.cpp) and a simple Makefile show how to compile it and which libraries to link.
The Makefile uses g++ but the code compile also with clang++.
The use is simple: the yasap executable accept only one command line parameter, the audio file, and play it.
By example
$ ./yasap song.flac
When playing, the following keys/commands are enabled
p switch pause / play
q terminate and exit
right arrow seek forward 10 seconds
left arrow seek backward 10 seconds
up arrow seek forward 1 minute
down arrow seek backward 1 minute
page up seek forward 10 minutes
page down seek backward 10 minutes
home seek to preceding track (only for files with multiple tracks)
end seek to following track (only for files with multiple tracks)
