flac dev - Apr 2023 - Calling libFLAC from Java

Hello, I joined because this list is the preferred method of communication
according to web site, and I would like to tell you about something I've
been working with that perhaps you would like to include among the links on the
FLAC web site?

Since 2014, I have a system that runs as a service on a computer connected to my
stereo to play FLAC files, exposing a web interface for playback control. I
created it for my personal use, but have lately made it more streamlined and
configurable to make possible for others to use.

The system includes a FLAC decoding and playing program of my own, because the
player utilities I could find did not live up to my standards (the main problem
being that they didn't cache data from the next track until the current one
had stopped playing, which created annoying gaps between tracks, especially when
playing from a disk that was NFS mounted over wifi). I wrote this in Java, first
using jFLAC for FLAC decoding, but a couple of years ago I switched to using the
actual libFLAC to get the full power of it, invoking it through JNI (the Java
native interface), meaning that I had to put a little bit of C code as a bridge
between Java and libFLAC.

I put a blog post about FLAC decoding in Java on my website, and a few months
ago I noticed that most of the visitors on the site came because they had
searched for that topic. I thought that maybe I should make it easier for people
who want to do this, so when I did some refactoring recently I made a separate
package for just the FLAC decoding, with the Java interface improved, and put it
into its own tarball with simplified instructions.

If you are interested, the website is https://klipspringer.avadeaux.net/
<https://klipspringer.avadeaux.net/> and the page specifically about the
FLAC decoding package is https://klipspringer.avadeaux.net/guide/flac-decoding/

Hi Jesper,

Thanks for reaching out. The links page on the FLAC website needs some
pruning. I'm afraid there are a lot of dead links there. I can include
your effort here as a library wrapper though:
https://github.com/ietf-wg-cellar/flac-specification/wiki/Implementations

Anyway, nice to see that libFLAC can be used for Java. As far as I am
aware, libFLAC was only available for Java through Exoplayer, and I'm
not sure whether that works outside of an Android environment. There
is a native FLAC encoder and decoder implementation though:
https://github.com/nayuki/FLAC-library-Java That might not be as
feature complete as libFLAC though, I haven't tried.

Kind regards, Martijn van Beurden
