transfering a AudioTrack object

FlashOnFire commented 6 years ago

Hello, I want to transfer a AudioTrack with an RMI setup but the object AudioTrack isn't Serializable. Can you make it implements Serializable please ?

Take a look at this

    public static AudioTrack toAudioTrack(String message) throws IOException {
        byte[] b64 = Base64.decodeBase64(message);
        ByteArrayInputStream bais = new ByteArrayInputStream(b64);
        return Player.PLAYER_MANAGER.decodeTrack(new MessageInput(bais)).decodedTrack;
    }

    public static String toMessage(AudioTrack track) throws IOException {
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        Player.PLAYER_MANAGER.encodeTrack(new MessageOutput(baos), track);
        return Base64.encodeBase64String(baos.toByteArray());
    }

Hi,

I have a similar issue because with this kind of transfer, I can't play some mp3 files. Here's the stack trace :

The machine you're trying to play it on doesn't have that file at that location. The serialized AudioTrack doesn't contain the file itself.

FlashOnFire commented 6 years ago

How can I do then ?

sedmelluq commented 6 years ago

Plenty of ways:

Only serialize local files if you are planning to load them on the same machine.
Make your files available over the network and use URLs instead.
Create some weird network drive thingy so that both machines see the same disk (not recommended).
Transfer the file to the other machine when necessary (not recommended).

This is not really related to Lavaplayer anymore since it is not meant to be and will not be an implementation of rysnc.

Okay, thanks for your help !
