Audacious - OLD, PLEASE USE GITHUB DISCUSSIONS/ISSUES

What kind of plugin? What do you want it to do?

the plugin that can search musics in the specific website

Okay, in that case I suggest you start by developing a stand-alone GTK+ program to implement the search function. Once the UI is working and the program can retrieve playable URIs from the website, post the code somewhere and I can help you turn it into a plugin.

Okay, I need a few days

Hello,I want the plug-in provide a function that can play music online and a function that can add some music in the music list. Some functions have not completed, i must complete this player after translated it to a pulg-in ,please help me to translated it to a pulg-in,thanks.
The sources code is in the https://github.com/hysteria-Wu/Baidu-Downloads

Does it compile correctly for you? I get these errors:

The program haven't any wrong on my computer, I think maybe your computer haven't json library. I have added the json library to the project, tell G++ the path of the library by change the JSON_PATH variable in the makefile.
If my library can't compile on your computer, you can download it by the website http://sourceforge.net/projects/jsoncpp/ .
the new source code are in the attachment

I installed jsoncpp from the Arch Linux repository. Still no go:
http://pastebin.com/raw.php?i=nRJMfjCP

Please don't waste my time. I'm willing to help but not to do your work for you.

I'm sorry! The fllowing attachment have removed jsoncpp library.
If still can't compile, so thank you for your help.
I will try to compile into a plug-in, not to bothre you.
Thank you!

It compiles fine, but it crashes when I do a search. Take your time and get it working correctly as a standalone search program; then we'll look at converting it into a plugin. Okay?

ok

In my newly installed archLinux test and there is no problem, here is the modified

I noticed you are using C signals to communicate between threads. Don't. It won't work in Audacious and would be dangerous even if it did work. If you need to run something in the main thread, use g_idle_add().

I've added the necessary boilerplate code to make this into an Audacious plugin (and fixed the thread communication). Take a look here:
https://github.com/jlindgren90/audacious-baidu-plugin/commit/ae92642faef1fdb993191285837dd51aed58b90d

Once you have a playable URL, you can just add some code like the following to play it:

#include <audacious/drct.h>

const char *url = ...
aud_drct_pl_open(url);

Thank you very much
