On Android SDL_RWFromFile cleverly reads from the APK archive's assets folder via the JNI. This is great, but for streaming music it's a problem because it's not thread-safe. This shouldn't surprise anyone: streaming data from a zip file, through java, the JNI, SDL, SDL_mixer... it's a recipe for disaster. As a result I'm exporting the files I want to stream to the sdcard first, then streaming them (safely) from there. At least that's the idea. Trouble is Mixer_LoadMUS itself calls upon SDL_RWFromFile, hence Mixer_LoadMUS("/sdcard/data/music.ogg") calls SDL_RWFromFile("/sdcard/data/music.ogg") which, unless I've very much mis-read the situation, goes looking for "/sdcard/data/music.ogg" in the assets folder of the APP (?). The code that does this trick is *line 448 of SDL_rwops.c **#if defined(ANDROID) rwops = SDL_AllocRW(); if (!rwops) return NULL; /* SDL_SetError already setup by SDL_AllocR</pre> William Dyce 2012-05-25T23:12:02 http://comments.gmane.org/gmane.comp.lib.sdl/56418 <pre>Is there any way to control and interact with the keyboard GUI on the iPad/iPhone with SDL2? It would be cool if there was a function to show and hide it, and when text is entered for some sort of SDL_KeyboardEvent to be triggered. But I couldn't find any current way to do this via SDL2. I suppose I could implement my own keyboard GUI, but that seems like reinventing the wheel. I suppose I could use some non-SDL code to show/hide the keyboard, but it would be cool if these were more closely integrated with SDL somehow so all iPad/iPhone developers had a standardized way to implement keyboard functionality. _______________________________________________ SDL mailing list SDL&lt; at &gt;lists.libsdl.org http://lists.libsdl.org/listinfo.cgi/sdl-libsdl.org </pre> Trev 2012-05-25T03:09:11 http://comments.gmane.org/gmane.comp.lib.sdl/56417 <pre>I am porting my program from mac/windows to the iPad. Up until now, I have been using the GLUT functions for drawing text, such as: glutBitmapCharacter (GLUT_BITMAP_HELVETICA_10,theString[i]); But those functions are not supported on the iPad, so I am trying to use SDL_ttf for text. There are 2 examples that demonstrate SDL_ttf. http://lackeyccg.com/glfont.c shows how things are done with OpenGL. http://lackeyccg.com/showfont.c shows how things are done with just SDL. I'm not sure what is the better method for my uses. I am using text for essentially 3 kinds of uses: Labels for things like buttons and menus.

There was a patch a few months ago that added "timestamp" to the SDL_Event structure. Has anyone looked into using it to get more precise input events? It looks like it is set when the event is created (when SDL_PumpEvents is called). Would the best approach be multithreading, splitting the event handling from the video handling? From the wiki, it looks like SDL_PumpEvents has to be called from the same thread that initialized the graphics.

Runtime Libraraies? Development Libraries? 2. On a linux server, I don't a root permission, can I install them in my local directory? I've tried rpm package, which seems to need root permission because I got the error as "error: can't create transaction lock on /var/lib/rpm/__db.000". Can I use source code to build a library? I'd appreciate if you could provide a procedure. 3. How to distribute it? Must it be with runtime libraries?

This causes all axes after ABS_MISC to be remapped to axis 0, because the abs_map table is initialised to zero. In practice this makes joysticks such as the PS3 SixAxis gamepad almost unusable. As a simple fix I suggest replacing ABS_MISC with ABS_MAX around line 705 in src/joystick/linux/SDL_sysjoystick.c so that all axes including the accelerometer ones are available.

The engine has reached a level of complexity that I feel it would be beneficial to have a external debugging program to aid in development. More precisely I would like to be able to pause/unpause the game and track objects [and their variables] without too much extra coding effort. I'll probably be writing the debugging application in python, but thats not terribly relevant to the question. My question is how should implement inter-process communications ? What libraries could I use to achieve communication in-between two programs quickly and painlessly ? (SDL_Net, Sockets, D-Bus, etc ...) Development is almost exclusively on Linux so I don't care if it would break cross platform compatibility. If anyone has some words of wisdom it would be greatly appreciated. </pre> Jason White 2012-05-16T00:56:08 http://comments.gmane.org/gmane.comp.lib.sdl/56340 <pre>I know this has been done over and over on the mailing list, and if this is a more appropriate question for OpenGL, I'll ask over at gamedev.

This has been discussed in this forum entry (there is a workaround provided): http://forums.libsdl.org/viewtopic.php?t=7160 This is due to the 'Jump to order' command being ignored while the file is being played. http://www.milkytracker.org/docs/MilkyTracker.html#fxBxx In my particular case, my game uses a mod file containing multiple music loops. Music loops are switched dynamically by the game using Mix_SetMusicPosition(position), which has the particular behaviour of setting the pattern being played in the case of a mod file. Having SDL_mixer ignoring the 'Jump' commands totally breaks the playback of the music in my case. The reason for mod playback not supporting loops is that this has been explicitely disabled in the MOD_new_RW() function of the music_mod.c file, with the line: module-&gt;loop = 0; (see source code below) Is there any reason for this?

I'm having some problems with scaled blitting.  I've got an 8-bit, paletted surface, and I'm creating another surface with the same pixel format and the same palette, but twice as large in both dimensions.  I want to blit the old image onto the new one to scale it up. It's been quite a hassle getting that to work in the first place, since for some inexplicable reason SDL_LowerBlitScaled doesn't seem to like paletted images and redirects me to SDL_LowerBlit instead, but without anything having set up the proper flags for SDL_LowerBlit to work, so what I end up with is no blit taking place because SDL_MapSurface can't find anything that matches the flags. So I ended up calling SDL_SoftStretch instead, which works just fine... until I tried to composite a second image over the top of it.  It did the stretch-blit but it didn't respect the colorkey, so instead of compositing, I got the second image and that's all.

This is adds a bit of extra overhead that could be otherwise avoided by the use of function pointers. This patch adds a table of 4 function pointers in SIMD-enabled builds that are used instead. When first called, the function pointer directs to a detection routine that detects the best version, saves that pointer, then executes it. This removes the extra branch that typically occurs in code, such as "if(firstTime) setupPointers()", instead replacing it with a detect-then-execute function. This is multithread-safe, since at no time does executing a function pointer produce incorrect results, and two threads executing the detection at the same time will save the same function pointer into the same location, guaranteeing identical results as the </pre> Patrick Baggett 2012-05-10T23:00:32 Search the mailing list at Gmane query http://search.gmane.org/?group=$group=gmane.comp.lib.sdl
