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.

| 3568 | 2 Using SDL 1.3 under Windows with the OpenWatcom compiler |
| 3 | |
| 1773 | 4 ==================================================== |
| 5 | |
| 6 Prerequisites | |
| 7 ------------- | |
| 8 | |
| 3568 | 9 I have done the port under Windows XP Professional with SP2 installed. |
| 10 Windows 2000 should also be working. I'm not so sure about ancient Windows NT, | |
| 1773 | 11 since only DirectX 3 is available there. Building should be possible, |
| 12 but running the compiled applications will probalbly fail with | |
| 13 SDL_VIDEODRIVER=directx. The windib driver should work, though. | |
| 14 | |
| 15 To compile and use the SDL with Open Watcom you will need the following: | |
| 3568 | 16 - Open Watcom compiler. I used version 1.8. The environment variables |
| 1773 | 17 PATH, WATCOM and INCLUDE need to be set appropriately - please consult |
| 18 the OpenWatcom documentation and instructions given during the | |
| 19 installation of the compiler. | |
| 20 My setup looks like this in owvars.bat: | |
| 3568 | 21 set WATCOM=C:\dev\ow18 |
| 1773 | 22 set INCLUDE=%WATCOM%\h;%WATCOM%\h\nt |
| 23 set PATH=%PATH%;%WATCOM%\binnt;%WATCOM%\binw | |
| 3568 | 24 - A recent DirectX SDK. The library needs D3d9.h so at leat the |
| 25 directx 9 sdk is to be used. I used DirectX 10 SDK from August 2009 | |
| 26 taken directly from the microsoft site. | |
| 27 - The SDL 1.3 sources from Subversion | |
| 1773 | 28 - The file Watcom-Win32.zip (now available in Subversion) |
| 29 | |
| 30 | |
| 31 Building the Library | |
| 32 -------------------- | |
| 33 | |
| 34 1) In the SDL base directory extract the archive Watcom-Win32.zip. This | |
| 35 creates a subdirectory named 'watcom'. | |
| 36 2) The makefile expects the environment variable DXDIR to be set to the | |
| 3568 | 37 base directory of a DirectX SDK. I have tried the August 2009 |
| 38 DirectX SDK from Microsoft | |
| 1773 | 39 You can also edit the makefile directly and hard code your path to |
| 40 the SDK on your system. | |
| 41 I have this in my setup: | |
| 3568 | 42 set DXDIR=..\dx10 |
| 1773 | 43 3) Enter the watcom directory and run |
| 44 wmake sdl | |
| 45 4) All tests from the test directory are working and can be built by | |
| 46 running | |
| 47 wmake tests | |
| 48 | |
| 49 Notes: | |
| 50 | |
| 51 The makefile offers some options to tweak the way the library is built. | |
| 52 You have at your disposal the option to build a static (default) | |
| 53 library, or a DLL (with tgt=dll). You can also choose whether to build | |
| 54 a Release (default) or a Debug version (with build=debug) of the tests | |
| 55 and library. Please consult the usage comment at the top of the | |
| 56 makefile for usage instructions. | |
| 57 | |
| 58 If you specify a test target (i.e. 'wmake tests' for all tests, or | |
| 59 selected targets like 'wmake testgl testvidinfo testoverlay2'), the | |
| 60 tests are always freshly compiled and linked. This is done to | |
| 61 minimise hassle when switching between library versions (static vs. | |
| 62 DLL), because they require subtly different options. | |
| 63 Also, the test executables are put directly into the test directory, | |
| 64 so they can find their data files. The clean target of the makefile | |
| 65 removes the test executables and the SDL.dll file from the test | |
| 66 directory. | |
| 67 | |
| 68 To use the library in your own projects with Open Watcom, you can use | |
| 69 the way the tests are built as base of your own build environment. | |

| 118 There is room for further improvement: | |
| 119 - Test joystick functionality. | |
| 120 - Investigate fading issue in 'testwin' test. | |
| 121 - Fix the UTF-8 support. | |
