87bc1fb5	2018-08-28T12:57:51	GLES2: Get sin/cos out of vertex shader The only place angle is activated and causes effect is RenderCopyEx. All other methods which use vertex shader, leave angle disabled and cause useless sin/cos calculation in shader. To get around shader's interface is changed to a vector that contains results of sin and cos. To behave properly when disabled, cos value is set with offset -1.0 making 0.0 default when deactivated. As nice side effect it simplifies GLES2_UpdateVertexBuffer: All attributes are vectors now. Additional background: * On RaspberryPi it gives a performace win for operations. Tested with [1] numbers go down for 5-10% (not easy to estimate due to huge variation). * SDL_RenderCopyEx was tested with [2] * It works around left rotated display caused by low accuracy sin implemetation in RaspberryPi/VC4 [3] [1] https://github.com/schnitzeltony/sdl2box [2] https://github.com/schnitzeltony/sdl2rendercopyex [3] https://github.com/anholt/mesa/issues/110 Signed-off-by: Andreas M?ller <schnitzeltony@gmail.com>

eb14b635	2018-05-07T19:52:25	Fixed bug 4134 - Render targets lose scale quality after minimizing a fullscreen window Olli-Samuli Lehmus If one creates a window with the SDL_WINDOW_FULLSCREEN_DESKTOP flag, and creates a render target with SDL_SetHint(SDL_HINT_RENDER_SCALE_QUALITY, "linear"), and afterwards sets SDL_SetHint(SDL_HINT_RENDER_SCALE_QUALITY, "nearest"), after minimizing the window, the scale quality hint is lost on the render target. Textures however do keep their interpolation modes.

a6a4e27a	2017-11-12T22:51:12	Updated SDL's YUV support, many thanks to Adrien Descamps New functions get and set the YUV colorspace conversion mode: SDL_SetYUVConversionMode() SDL_GetYUVConversionMode() SDL_GetYUVConversionModeForResolution() SDL_ConvertPixels() converts between all supported RGB and YUV formats, with SSE acceleration for converting from planar YUV formats (YV12, NV12, etc) to common RGB/RGBA formats. Added a new test program, testyuv, to verify correctness and speed of YUV conversion functionality.
9fd0d619	2017-10-18T08:52:04	Fixed bug 3821 - Allow SDL_CreateWindow and SDL_CreateRenderer with OpenGL ES 3.0 (GLES3) for Angle (Windows) Carlos Angle supports GLES3 but when using these functions (SDL_CreateWindow and SDL_CreateRenderer), defaults again to GLES2.0. A current workaround (hack) to retrieve a GLES3.0 context with Angle is: 1) set SDL_GL_SetAttribute(SDL_GL_CONTEXT_MAJOR_VERSION, 3); SDL_GL_SetAttribute(SDL_GL_CONTEXT_MINOR_VERSION, 0); after InitSDL AND after calling SDL_CreateWindow (before SDL_CreateRenderer) 2) Comment lines 2032-2044 in SDL_render_gles2.c, funtion GLES2_CreateRenderer window_flags = SDL_GetWindowFlags(window); if (!(window_flags & SDL_WINDOW_OPENGL) \|\| profile_mask != SDL_GL_CONTEXT_PROFILE_ES \|\| major != RENDERER_CONTEXT_MAJOR \|\| minor != RENDERER_CONTEXT_MINOR) { changed_window = SDL_TRUE; SDL_GL_SetAttribute(SDL_GL_CONTEXT_PROFILE_MASK, SDL_GL_CONTEXT_PROFILE_ES); SDL_GL_SetAttribute(SDL_GL_CONTEXT_MAJOR_VERSION, RENDERER_CONTEXT_MAJOR); SDL_GL_SetAttribute(SDL_GL_CONTEXT_MINOR_VERSION, RENDERER_CONTEXT_MINOR); if (SDL_RecreateWindow(window, window_flags \| SDL_WINDOW_OPENGL) < 0) { goto error; } } This retrives a GLES3 context as confirmed using glGetString(GL_VERSION). This should be fixed by modifying a few if's.
e9652b19	2017-10-06T16:50:24	Fixed bug 3857 - SDL_ConvertPixels misses YUV conversions Sylvain Few issues with YUV on SDL2 when using odd dimensions, and missing conversions from/back to YUV formats. 1) The big part is that SDL_ConvertPixels() does not convert to/from YUV in most cases. This now works with any format and also with odd dimensions, by adding two internal functions SDL_ConvertPixels_YUV_to_ARGB8888 and SDL_ConvertPixels_ARGB8888_to_YUV (could it be XRGB888 ?). The target format is hard coded to ARGB888 (which is the default in the internal of the software renderer). In case of different YUV conversion, it will do an intermediate conversion to a ARGB8888 buffer. SDL_ConvertPixels_YUV_to_ARGB8888 is somehow redundant with all the "ColorDitherMod". But it allows some completeness of SDL_ConvertPixels to handle all YUV format. It also works with odd dimensions. Moreover, I did some benchmark(SDL_ConvertPixel vs Color32DitherYV12Mod1X and Color32DitherYUY2Mod1X). gcc-6.3 and clang-4.0. gcc performs better than clang. And, with gcc, SDL_ConvertPixels() performs better (20%) than the two C function Color32Dither(). For instance, to convert 10 times a 3888x2592 image, it takes ~195 ms with SDL_ConvertPixels and ~235 ms with Color32Dither(). Especially because of gcc vectorize feature that optimises all conversion loops (-ftree-loop-vectorize). Nb: I put no image pitch for the YUV buffers. because it complexify a little bit the code and the API : There would be some ambiguity when setting the pitch exactly to image width: would it a be pitch of image width (for luma and chroma). or just contiguous data ? (could set pitch=0 for the later). 2) Small issues with odd dimensions: If width "w" is odd, luma plane width is still "w" whereas chroma planes will be "(w + 1)/2". Almost the same for odd h. Solution is to strategically substitute "w" by "(w+1)/2" at the good places ... - In the repository, SDL_ConvertPixels() handles YUV only if yuv source format is exactly the same as YUV destination format. It basically does a memcpy of pixels, but it's done incorrectly when width or height is odd (wrong size of chroma planes). This is fixed. - SDL Renderers don't support odd width/height for YUV textures. This is fixed for software, opengl, opengles2. (opengles 1 does not support it and fallback to software rendering). This is not* fixed for D3D and D3D11 ... (and others, psp ?) Only two Dither function are fixed ... not sure if others are really used. - This is not possible to create a NV12/NV12 texture with the software renderer, whereas other renderers allow it. This is fixed, by using SDL_ConvertPixels underneath. - It was not possible to SDL_UpdateTexture() of format NV12/NV21 with the software renderer. this is fixed. Here's also two testcases: - that do all combination of conversion. - to test partial UpdateTexture

ecea3c4a	2016-10-01T13:33:32	Fixed bug 3169 - GLES2_CreateRenderer does not check SDL_GL_GetAttribute result, causing use of uninitialized data Yann Dirson When attempting to force use of opengles2 renderer with: int wanted_renderer = -1; for (int i = 0; i < numrenderers; i++) { SDL_RendererInfo renderer_info; if (SDL_GetRenderDriverInfo(i, &renderer_info) != 0) { SDL_LogError(SDL_LOG_CATEGORY_APPLICATION, "Couldn't get renderer driver info: %s\n", SDL_GetError()); quit(2); } std::cerr << "Renderer " << i << " '" << renderer_info.name << "': flags=0x" << std::hex << renderer_info.flags << std::dec << ", " << renderer_info.num_texture_formats << " texture formats, max=" << renderer_info.max_texture_width << "x" << renderer_info.max_texture_height << "\n"; if (!strcmp(renderer_info.name, "opengles2")) { std::cerr << " selecting!\n"; wanted_renderer = i; } } renderer = SDL_CreateRenderer(window, wanted_renderer, 0); ... on banana pi or raspberry pi I get an error like the following (the actual context profile value varies, being used uninitialized) ERROR: Couldn't create renderer: Unknown OpenGL context profile 900 With this patch I get the following, which should help more pointing to a real problem: ERROR: Couldn't create renderer: Failed getting OpenGL glGetString entry point I pushed a patch (based on master branch of unofficial git mirror): https://github.com/O-Computers/SDL/commit/550389c89f4e73a0a5294f95b9f6e6c18ba48509 I'll be opening a different bug for the underlying issue.
77305d47	2016-10-01T11:46:32	Fixed bug 3345 - SDL_RenderClear inconsistency with ClipRect Simon Hug The description of the SDL_RenderClear function in the SDL_render.h header says the following: "This function clears the entire rendering target, ignoring the viewport." The word "entire" implies that the clipping rectangle set with SDL_RenderSetClipRect also gets ignored. This is left somewhat ambiguous if only the viewport is mentioned. Minor thing, but let's see what the implementations actually do. The software renderer ignores the clipping rectangle when clearing. It even has a comment on this: /* By definition the clear ignores the clip rect */ Most other render drivers (opengl, opengles, opengles2, direct3d, and psp [I assume. Can't test it.]) use the scissor test for the ClipRect and don't disable it when clearing. Clearing will only happen within the clipping rectangle for these drivers. An exception is direct3d11 which uses a clear function that ignores the scissor test.
061cc5e7	2016-10-01T11:38:53	Fixed bug 3349 - GLES2_RenderReadPixels doesn't use target texture format Simon Hug The OpenGL ES 2 renderer does not check the target texture format when using SDL_RenderReadPixels and just always uses ABGR8888. This can result in swapped or wrong colors. The attached patch adds a check and selects the target texture format, if a texture is set as the target.
51d6371e	2016-10-01T11:34:04	Fixed bug 3350 - GL renderers don't need to flip rows after reading back pixels from the target texture Simon Hug All OpenGL renderers always flip the rows of the pixels that come from glReadPixels. This is unnecessary for target textures since these are already top down. Also, the rect->y value can be used directly for target textures for the same reason. I don't see any code that would handle the logical render size for target textures. Or am I missing something? The attached patch makes the renderers only the flip rows if the data comes from the default framebuffer.

0e45984f	2015-06-21T17:33:46	Fixed crash if initialization of EGL failed but was tried again later. The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly uninitialized data structure if loading the library first failed. A later try to use EGL then skipped initialization and assumed it was previously successful because the data structure now already existed. This led to at least one crash in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was dereferenced to make a call to eglBindAPI().

b88ca1b4	2015-02-10T16:28:56	the last parameter of XChangeProperty is the number of elements.. and when the element format is 32.. the element is "long" so we have 5 long elements here. Yes this seems confusing as on mac+linux Long is either 32 or 64bits depending on the architecture, but this is how the X11 protocol is defined. Thus 5 is the correct value for the nelts here. Not 5 or 10 depending on the architecture. More info on the confusion https://bugs.freedesktop.org/show_bug.cgi?id=16802
b48e54aa	2015-01-26T22:00:29	Fixed bug 2802 - [patch] Fix android build compiling in wrong filesystem implementation Jonas Kulla The configure script didn't differentiate between Linux and Android, unconditionally compiling in the unix implementation of SDL_sysfilesystem.c. I'm probably one of the very few people building SDL for android using classic configure + standalone toolchain, so this has gone undetected all along.

e8f8e672	2014-06-21T12:38:46	Fixed bug 2595 - Padded, non-contiguous YUV does not display correctly using OpenGL ES 2.0 renderer Alvin The new OpenGL ES 2.0 YUV Texture support does not correctly display padded, non-contiguous YUV data. I am using SDL2 95bd3d33482e (as provided by 'hg id --id') from Mercurial. The YUV data I am using is provided by the FFMPEG family of libraries. According to FFMPEG's documentation, "The linesize [pitch] may be larger than the size of usable data -- there may be extra padding present for performance reasons." The dimensions of the video file that I am using are 480x360. What I get from FFMPEG is a Ypitch of 512, and Upitch and Vpitch are both 256. When I pack new Y, U and V buffers with only the "usable" data (Ypitch is 480 and Upitch and Vpitch are both 240), and use those new buffers, the image is display correctly. It appears that the Ypitch, Upitch and Vpitch parameters are not being used by SDL_UpdateYUVTexture(). I use SDL_PIXELFORMAT_YV12 for my YUV texture, however, the same results are seen when I use SDL_PIXELFORMAT_IYUV. Not sure if this is related or not, but when I render the YUV texture (padded and unpadded) to a RGB24 texture, the resulting image is greyscale (or could by just the Y channel). The URL field for this bug entry is set to my email (SDL mailing list archive) which includes an example image of what I see when rendering padded, non-contiguous YUV data.

This is needed on platforms where both GL and GLES 1/2 surfaces are supported by the video backend, requiring that the window be recreated when switching between context types.
b331ada8	2014-02-09T01:49:01	Fixed bug 2354 - [ES 2.0] SDL_RenderClear clears render target with wrong color ny00 SDL_RenderClear clears a render target with the wrong color, if the opengles2 renderer driver is used and the target texture's format is SDL_PIXELFORMAT_ARGB8888. The bug is not reproduced if SDL_PIXELFORMAT_ABGR8888 is used as the texture format (the first from the renderer's list). It is further not reproduced using any of the following renderer drivers: opengl, opengles (apparently powered by Gallium3D), software. Finally, the correct color can be drawn using SDL_RenderFillRect (instead of SDL_RenderClear). A few details about the current setup: - OS: Ubuntu 12.04 for x86_64 - GPU: GeForce GTX 460 - GPU driver version: 331.20-0ubuntu1~xedgers~precise1 (from the xorg-edgers PPA) --- Seth Williams Sam, It appears that the clear just needs to take the render target format into consideration.

GLES2: Get sin/cos out of vertex shader The only place angle is activated and causes effect is RenderCopyEx. All other methods which use vertex shader, leave angle disabled and cause useless sin/cos calculation in shader. To get around shader's interface is changed to a vector that contains results of sin and cos. To behave properly when disabled, cos value is set with offset -1.0 making 0.0 default when deactivated. As nice side effect it simplifies GLES2_UpdateVertexBuffer: All attributes are vectors now. Additional background: * On RaspberryPi it gives a performace win for operations. Tested with [1] numbers go down for 5-10% (not easy to estimate due to huge variation). * SDL_RenderCopyEx was tested with [2] * It works around left rotated display caused by low accuracy sin implemetation in RaspberryPi/VC4 [3] [1] https://github.com/schnitzeltony/sdl2box [2] https://github.com/schnitzeltony/sdl2rendercopyex [3] https://github.com/anholt/mesa/issues/110 Signed-off-by: Andreas M?ller <schnitzeltony@gmail.com>

Textures however do keep their interpolation modes.

Fixed bug 3821 - Allow SDL_CreateWindow and SDL_CreateRenderer with OpenGL ES 3.0 (GLES3) for Angle (Windows) Carlos Angle supports GLES3 but when using these functions (SDL_CreateWindow and SDL_CreateRenderer), defaults again to GLES2.0. A current workaround (hack) to retrieve a GLES3.0 context with Angle is: 1) set SDL_GL_SetAttribute(SDL_GL_CONTEXT_MAJOR_VERSION, 3); SDL_GL_SetAttribute(SDL_GL_CONTEXT_MINOR_VERSION, 0); after InitSDL AND after calling SDL_CreateWindow (before SDL_CreateRenderer) 2) Comment lines 2032-2044 in SDL_render_gles2.c, funtion GLES2_CreateRenderer window_flags = SDL_GetWindowFlags(window); if (!(window_flags & SDL_WINDOW_OPENGL) || profile_mask != SDL_GL_CONTEXT_PROFILE_ES || major != RENDERER_CONTEXT_MAJOR || minor != RENDERER_CONTEXT_MINOR) { changed_window = SDL_TRUE; SDL_GL_SetAttribute(SDL_GL_CONTEXT_PROFILE_MASK, SDL_GL_CONTEXT_PROFILE_ES); SDL_GL_SetAttribute(SDL_GL_CONTEXT_MAJOR_VERSION, RENDERER_CONTEXT_MAJOR); SDL_GL_SetAttribute(SDL_GL_CONTEXT_MINOR_VERSION, RENDERER_CONTEXT_MINOR); if (SDL_RecreateWindow(window, window_flags | SDL_WINDOW_OPENGL) < 0) { goto error; } } This retrives a GLES3 context as confirmed using glGetString(GL_VERSION). This should be fixed by modifying a few if's.

Fixed bug 3857 - SDL_ConvertPixels misses YUV conversions Sylvain Few issues with YUV on SDL2 when using odd dimensions, and missing conversions from/back to YUV formats. 1) The big part is that SDL_ConvertPixels() does not convert to/from YUV in most cases. This now works with any format and also with odd dimensions, by adding two internal functions SDL_ConvertPixels_YUV_to_ARGB8888 and SDL_ConvertPixels_ARGB8888_to_YUV (could it be XRGB888 ?). The target format is hard coded to ARGB888 (which is the default in the internal of the software renderer). In case of different YUV conversion, it will do an intermediate conversion to a ARGB8888 buffer. SDL_ConvertPixels_YUV_to_ARGB8888 is somehow redundant with all the "Color*Dither*Mod*". But it allows some completeness of SDL_ConvertPixels to handle all YUV format. It also works with odd dimensions. Moreover, I did some benchmark(SDL_ConvertPixel vs Color32DitherYV12Mod1X and Color32DitherYUY2Mod1X). gcc-6.3 and clang-4.0. gcc performs better than clang. And, with gcc, SDL_ConvertPixels() performs better (20%) than the two C function Color32Dither*(). For instance, to convert 10 times a 3888x2592 image, it takes ~195 ms with SDL_ConvertPixels and ~235 ms with Color32Dither*(). Especially because of gcc vectorize feature that optimises all conversion loops (-ftree-loop-vectorize). Nb: I put no image pitch for the YUV buffers. because it complexify a little bit the code and the API : There would be some ambiguity when setting the pitch exactly to image width: would it a be pitch of image width (for luma and chroma). or just contiguous data ? (could set pitch=0 for the later). 2) Small issues with odd dimensions: If width "w" is odd, luma plane width is still "w" whereas chroma planes will be "(w + 1)/2". Almost the same for odd h. Solution is to strategically substitute "w" by "(w+1)/2" at the good places ... - In the repository, SDL_ConvertPixels() handles YUV only if yuv source format is exactly the same as YUV destination format. It basically does a memcpy of pixels, but it's done incorrectly when width or height is odd (wrong size of chroma planes). This is fixed. - SDL Renderers don't support odd width/height for YUV textures. This is fixed for software, opengl, opengles2. (opengles 1 does not support it and fallback to software rendering). This is *not* fixed for D3D and D3D11 ... (and others, psp ?) Only *two* Dither function are fixed ... not sure if others are really used. - This is not possible to create a NV12/NV12 texture with the software renderer, whereas other renderers allow it. This is fixed, by using SDL_ConvertPixels underneath. - It was not possible to SDL_UpdateTexture() of format NV12/NV21 with the software renderer. this is fixed. Here's also two testcases: - that do all combination of conversion. - to test partial UpdateTexture

Fixed bug 3345 - SDL_RenderClear inconsistency with ClipRect Simon Hug The description of the SDL_RenderClear function in the SDL_render.h header says the following: "This function clears the entire rendering target, ignoring the viewport." The word "entire" implies that the clipping rectangle set with SDL_RenderSetClipRect also gets ignored. This is left somewhat ambiguous if only the viewport is mentioned. Minor thing, but let's see what the implementations actually do. The software renderer ignores the clipping rectangle when clearing. It even has a comment on this: /* By definition the clear ignores the clip rect */ Most other render drivers (opengl, opengles, opengles2, direct3d, and psp [I assume. Can't test it.]) use the scissor test for the ClipRect and don't disable it when clearing. Clearing will only happen within the clipping rectangle for these drivers. An exception is direct3d11 which uses a clear function that ignores the scissor test.

Fixed bug 3350 - GL renderers don't need to flip rows after reading back pixels from the target texture Simon Hug All OpenGL renderers always flip the rows of the pixels that come from glReadPixels. This is unnecessary for target textures since these are already top down. Also, the rect->y value can be used directly for target textures for the same reason. I don't see any code that would handle the logical render size for target textures. Or am I missing something? The attached patch makes the renderers only the flip rows if the data comes from the default framebuffer.

Fixed crash if initialization of EGL failed but was tried again later. The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly uninitialized data structure if loading the library first failed. A later try to use EGL then skipped initialization and assumed it was previously successful because the data structure now already existed. This led to at least one crash in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was dereferenced to make a call to eglBindAPI().

the last parameter of XChangeProperty is the number of elements.. and when the element format is 32.. the element is "long" so we have 5 long elements here. Yes this seems confusing as on mac+linux Long is either 32 or 64bits depending on the architecture, but this is how the X11 protocol is defined. Thus 5 is the correct value for the nelts here. Not 5 or 10 depending on the architecture. More info on the confusion https://bugs.freedesktop.org/show_bug.cgi?id=16802

Fixed bug 2595 - Padded, non-contiguous YUV does not display correctly using OpenGL ES 2.0 renderer Alvin The new OpenGL ES 2.0 YUV Texture support does not correctly display padded, non-contiguous YUV data. I am using SDL2 95bd3d33482e (as provided by 'hg id --id') from Mercurial. The YUV data I am using is provided by the FFMPEG family of libraries. According to FFMPEG's documentation, "The linesize [pitch] may be larger than the size of usable data -- there may be extra padding present for performance reasons." The dimensions of the video file that I am using are 480x360. What I get from FFMPEG is a Ypitch of 512, and Upitch and Vpitch are both 256. When I pack new Y, U and V buffers with only the "usable" data (Ypitch is 480 and Upitch and Vpitch are both 240), and use those new buffers, the image is display correctly. It appears that the Ypitch, Upitch and Vpitch parameters are not being used by SDL_UpdateYUVTexture(). I use SDL_PIXELFORMAT_YV12 for my YUV texture, however, the same results are seen when I use SDL_PIXELFORMAT_IYUV. Not sure if this is related or not, but when I render the YUV texture (padded and unpadded) to a RGB24 texture, the resulting image is greyscale (or could by just the Y channel). The URL field for this bug entry is set to my email (SDL mailing list archive) which includes an example image of what I see when rendering padded, non-contiguous YUV data.

Fixed bug 2354 - [ES 2.0] SDL_RenderClear clears render target with wrong color ny00 SDL_RenderClear clears a render target with the wrong color, if the opengles2 renderer driver is used and the target texture's format is SDL_PIXELFORMAT_ARGB8888. The bug is *not* reproduced if SDL_PIXELFORMAT_ABGR8888 is used as the texture format (the first from the renderer's list). It is further not reproduced using any of the following renderer drivers: opengl, opengles (apparently powered by Gallium3D), software. Finally, the correct color can be drawn using SDL_RenderFillRect (instead of SDL_RenderClear). A few details about the current setup: - OS: Ubuntu 12.04 for x86_64 - GPU: GeForce GTX 460 - GPU driver version: 331.20-0ubuntu1~xedgers~precise1 (from the xorg-edgers PPA) --- Seth Williams Sam, It appears that the clear just needs to take the render target format into consideration.

Fixes #2022, do not resume on Android when surfaceChanged If the app is in landscape mode and the user presses the power button, a pause is followed immediately by a surfaceChanged event because the lock screen is shown in portrait mode. This triggers a "false" resume. So, we just pause and resume following the onWindowFocusChanged events. Also, wait for SDL_APP_WILLENTERBACKGROUND and SDL_APP_DIDENTERBACKGROUND before blocking the event pump.
