kandi X-RAY | redsea Summary
redsea is a lightweight command-line FM-RDS decoder for Linux/macOS. It supports a large subset of RDS features. Decoded RDS groups are printed to the terminal as line-delimited JSON objects or, optionally, undecoded hex blocks (-x). Please refer to the wiki for input data formats. Redsea can be used with any RTL-SDR USB radio stick with the rtl_fm tool, or any other SDR via csdr, for example. It can also decode raw ASCII bitstream, the hex format used by RDS Spy, and audio files containing multiplex signals (MPX). These use cases are documented in the wiki.

QUESTION
I'm trying to play an audio file. In my IDE (intellij) that works completely fine, but when running in a JAR, I get the error java.io.FileNotFoundException: D:\soni801\Documents\Redsea Productions\The Great X Wars\alpha-0.0.7.1.jar\audio\click.au (The system cannot find the path specified)
The file's location inside the JAR is audio/click.au
, and the JAR is located at D:\soni801\Documents\Redsea Productions\The Great X Wars\alpha-0.0.7.1.jar
which afaik should make the absolute path D:\soni801\Documents\Redsea Productions\The Great X Wars\alpha-0.0.7.1.jar\audio\click.au
, however the system can't find a file at this location? What's happening here?
This is the code in my AudioPlayer.java
file:
ANSWER
Answered 2020-Jul-22 at 06:21The AudioSystem.getAudioInputStream
method is overloaded and can accept a File
, a URL
or an InputStream
as an argument. Of these, URL
is usually the best choice.
It's advantage over File
is that a URL
can address a file within a jar, which a File
cannot do.
It's advantage over InputStream
is that additional conditions are imposed: the audio file must support mark
and reset
methods. My experience with audio files is that it's kind of hit or miss as to whether this will be possible or not. I confess I don't know the specifics as to why.
To obtain a URL from your jar, the simplest form it perhaps the following:
