Fixed bug #1011 Daniel Ellis 2010-06-25 15:20:31 PDT SDL based applications sometimes display the wrong application name in the Sound Preferences dialog when using pulseaudio. I can see from the code that the SDL pulse module is initiating a new pulse audio context and passing an application name using the function get_progname(). The get_progname() function returns the name of the current process. However, the process name is often not a suitable name to use. For example, the OpenShot video editor is a python application, and so "python" is displayed in the Sound Preferences window (see Bug #596504), when it should be displaying "OpenShot". PulseAudio allows applications to specify the application name, either at the time the context is created (as SDL does currently), or by special environment variables (see http://www.pulseaudio.org/wiki/ApplicationProperties). If no name is specified, then pulseaudio will determine the name based on the process. If you specify the application name when initiating the pulseaudio context, then that will override any application name specified using an environment variable. As libsdl is a library, I believe the solution is for libsdl to not specify any application name when initiating a pulseaudio context, which will enable applications to specify the application name using environment variables. In the case that the applications do not specify anything, pulseaudio will fall back to using the process name anyway. The attached patch removes the get_progname() function and passes NULL as the application name when creating the pulseaudio context, which fixes the issue.

 *  
 *  \section intro_sec Introduction
 *  
 *  This is the Simple DirectMedia Layer, a general API that provides low
 *  level access to audio, keyboard, mouse, joystick, 3D hardware via OpenGL,
 *  and 2D framebuffer across multiple platforms.
 *  
 *  The current version supports Windows, Windows CE, Mac OS X, Linux,
 *  FreeBSD, NetBSD, OpenBSD, BSD/OS, Solaris, and QNX. The code contains
 *  support for other operating systems but those are not officially supported. 
 *  
 *  SDL is written in C, but works with C++ natively, and has bindings to
 *  several other languages, including Ada, C#, Eiffel, Erlang, Euphoria,
 *  Guile, Haskell, Java, Lisp, Lua, ML, Objective C, Pascal, Perl, PHP,
 *  Pike, Pliant, Python, Ruby, and Smalltalk.
 *  
 *  This library is distributed under GNU LGPL version 2, which can be
 *  found in the file  "COPYING".  This license allows you to use SDL
 *  freely in commercial programs as long as you link with the dynamic
 *  library.
 *  
 *  The best way to learn how to use SDL is to check out the header files in
 *  the "include" subdirectory and the programs in the "test" subdirectory.
 *  The header files and test programs are well commented and always up to date.
 *  More documentation is available in HTML format in "docs/index.html", and
 *  a documentation wiki is available online at:
 *  	http://www.libsdl.org/cgi/docwiki.cgi
 *  
 *  The test programs in the "test" subdirectory are in the public domain.
 *  
 *  Frequently asked questions are answered online:
 *  	http://www.libsdl.org/faq.php
 *  
 *  If you need help with the library, or just want to discuss SDL related
 *  issues, you can join the developers mailing list:
 *  	http://www.libsdl.org/mailing-list.php
 *  
 *  Enjoy!
