* vo_opengl: use EXT_disjoint_timer_query for timersJames Ross-Gowan2016-06-151-0/+16
| | | | | | This is the ES equivalent to ARB_timer_query. It enables the performance timers on ANGLE. All the added functions should be identical in semantics to their desktop GL equivalents.
* vo_opengl: fix framebuffer object namewm42016-06-151-3/+4
| | | | | | | | | The OpenGL 3.0+ and ES specs are quite clear on what values are accepted for the attachment object name parameter. And there's no overlap for the default framebuffer. Sigh. Probably fixes Mesa raising an error in this case and might fix #3251. Regression by the previous vo_opengl change.
* vo_opengl: use standard functions to retrieve display depthwm42016-06-1410-59/+21
| | | | | | | | | | | | | Until now, we've used system-specific API (GLX, EGL, etc.) to retrieve the depth of the default framebuffer. (We equal this to display depth and use the determined depth for dithering.) We can actually retrieve this value through standard GL API, and it works everywhere (except GLES 2 of course). This simplifies everything a great deal. egl_helpers.c is empty now. But I expect that some EGL boilerplate will be moved to it, so don't remove it yet.
* vo_opengl: hwdec_d3d11egl: remove ES2 swizzle special-casewm42016-06-131-2/+2
| | | | | | | | This was somehow done under the assumption that ANGLE would somehow always use RG in ES2 mode. But there's no basis for this. Even if ANGLE supports NV12 textures with drivers that do not allow for texture_rg, this cas eis too obscure to worry about. So do the robust and correct thing instead, and disable this code if texture_rg is not available.

* win32: use HINST_THISCOMPONENTJames Ross-Gowan2016-06-111-2/+5
| | | | | | | | | | | | | | | This is a common idiom used in MSDN docs and Raymond Chen's example programs to get a HINSTANCE for the current module, regardless of whether it's an .exe or a .dll. Using GetModuleHandle(NULL) for this is technically incorrect, since it always gets a handle to the .exe, even when the executing code (in libmpv) is running in a .dll. In this case, using the wrong HINSTANCE could cause namespace issues with window classes, since CreateWindowEx uses the HINSTANCE to search for the matching window class name. See: https://blogs.msdn.microsoft.com/oldnewthing/20050418-59/?p=35873 https://blogs.msdn.microsoft.com/oldnewthing/20041025-00/?p=37483
* vo_opengl: request core profile on X11/EGL toowm42016-06-101-0/+11
| | | | Avoids that some OpenGL implementation will pin it to 3.0.
* vo_opengl: increase the size limit for cached fileBin Jin2016-06-101-1/+1
| | | | | | This is mainly for the nnedi3 user shader. With all whose NN weights hardcoded into the shader source code, the shader file could be as large as 300 kB.
* vo_opengl: hwdec_d3d11eglrgb: remove some more unused fieldswm42016-06-091-30/+0
| | | | Not sure what/if I was thinking there.
* vo_opengl: fix d3d11 hardware decoding probing on Windows 7wm42016-06-094-0/+38
| | | | | | | | | | | | | | | Although D3D11 video decoding is unuspported on Windows 7, the associated APIs almost work. Where they fail is texture creation, where we try to create D3D11_BIND_DECODER surfaces. So specifically try to detect this situation. One issue is that once the hwdec interop is created, the damage is done, and it can't use another backend (because currently only 1 hwdec backend is supported). So that's where we prevent attempts to use it. It still can fail when trying to use d3d11va-copy (since that doesn't require an interop backend), but at that point we don't care anymore - dxva2(-copy) is tried before that anyway.
* vo_opengl: hwdec_d3d11eglrgb: remove unused fieldswm42016-06-091-3/+0
| | | | Leftovers.
* vo_opengl: hwdec_vdpau: remove minor code duplicationwm42016-06-081-13/+11
| | | | | Move unmap() to the top of the function, and replace some duplicated code with a call to it.
* vo_opengl: make user hook passes optionalNiklas Haas2016-06-083-16/+72
| | | | | | | | | | | | | | | | User hooks can now use an extra WHEN expression to specify when the shader should be run. For example, this can be used to only run a chroma scaling shader `WHEN CHROMA.w LUMA.w <`. There's a slight semantics change to user shaders: When trying to bind a texture that does not exist, a shader will now be silently skipped (similar to when the condition is false) instead of generating an error. This allows shader stages to depend on an optional earlier stage without having to copy/paste the same condition everywhere. (In other words: there's an implicit condition on all of the bound textures existing)
* vo_opengl: do not leak previous FBO when reallocating itwm42016-06-081-0/+2
| | | | WTF of the day.
* hwdec_d3d11eglrgb: reduce log level when probingJames Ross-Gowan2016-06-091-3/+5
| | | | | | | | | | When using --hwdec=auto, systems that don't provide D3D11_CREATE_DEVICE_VIDEO_SUPPORT, which probably includes all Windows Vista and 7 systems, will print an error message. Reduce the log level to verbose when probing and skip the error message entirely if d3d11.dll is not present. This commit is in a similar spirit to 991af7d.
* vo_opengl: hwdec_d3d11egl: remove broken code on error pathwm42016-06-081-1/+0
| | | | | If ID3D11Device_QueryInterface fails, "multithread" will be set to NULL. The _Release would just make it crash with a null pointer deref.
* vo_opengl: avoid outputting ultra-wide-gamut by defaultNiklas Haas2016-06-071-1/+13
| | | | | | | | | | | | The default behavior of vo_opengl has pretty much always been 'show the source colors as-is, without caring to adapt it to the target device'. This decision is mostly based on the fact that if we do anything else, lots of people will complain. With the rise of content like BT.2020, however, it turns out more people complain about this content being very desaturated than people complain about this content not matching VLC - so let's just map ultra-wide gamut content back down to standard gamut by default.
* vo_opengl: also collect upload perfdata for hwdecNiklas Haas2016-06-071-0/+4
| | | | | | Instead of measuring the actual upload time, this instead measures the time needed to render + map the texture via vdpau. These numbers are still useful, since they're part of the critical path.
* vo_opengl: expose performance timers as propertiesNiklas Haas2016-06-072-0/+19
| | | | | | | | | | | This is plumbed through a new VOCTRL, VOCTRL_PERFORMANCE_DATA, and exposed as properties render-time-last, render-time-avg etc. All of these numbers are in microseconds, which gives a good precision range when just outputting them via show-text. (Lua scripts can obviously still do their own formatting etc.) Signed-off-by: wm4 <wm4@nowhere>
* vo_opengl: add time queriesNiklas Haas2016-06-075-0/+208
| | | | | | | | | | | | | | | | | | To avoid blocking the CPU, we use 8 time objects and rotate through them, only blocking until the last possible moment (before we need access to them on the next iteration through the ring buffer). I tested it out on my machine and 4 query objects were enough to guarantee block-free querying, but the extra margin shouldn't hurt. Frame render times are just output at the end of each frame, via MP_DBG. This might be improved in the future. (In particular, I want to expose these numbers as properties so that users get some more visible feedback about render times) Currently, we measure pass_render_frame and pass_draw_to_screen separately because the former might be called multiple times due to interpolation. Doing it this way gives more faithful numbers. Same goes for frame upload times.
* vo_opengl: angle: prevent DXGI hooking Alt+EnterJames Ross-Gowan2016-06-071-0/+73
| | | | | | | | | | When ANGLE is using D3D11 and not running in DirectComposition mode, DXGI will hook the video window's message loop and override Alt+Enter to trigger a transition to exclusive fullscreen mode (which doesn't even work with mpv's renderer for some reason.) This behaviour can be disabled by getting a pointer to the IDXGIFactory associated with the D3D11 device and calling MakeWindowAssociation with the appropriate flags.
* vo_opengl: somewhat simplify suboption handling messwm42016-06-041-64/+16
| | | | | | | | | | | | | | | Enable m_sub_options_copy() to copy nested sub-options, and also enable it to create an option struct from defaults. We can get rid of most of the crap in assign_options() now. Calling handle_scaler_opt() to get a static allocation for scaler name is still needed. It's moved to reinit_scaler(), which seems to be a better place for it. Without it, dangling pointers could be created when options are changed. (And in fact, this fixes possible dangling pointers for window.name.) In theory we could create a dynamic copy, but that seemed even more messy. Chance of regressions.
* vo_opengl: cleanup icc + runtime option changing behaviorwm42016-06-043-43/+72
| | | | | | | | | | | | | | Commit 026b75e7 actually enabled changing icc options at runtime (via vo_cmdline), but it didn't quite work. In particular, changing the icc- profile option just kept the old profile, because it was cached accordingly. As part of this, change gl_lcms.opts from a struct to a pointer to a struct. We properly copy it, instead of allowing possibly dangling strings, like it was done in a working but unclean way before. Also, reinit the whole rendering chain when the auto icc profile changes, just like it's done when icc options are changed.
* vo_opengl: minor simplification to gl_lcms_set_memory_profile()wm42016-06-043-11/+11
| | | | | | Passing the bstr thing as pointer makes no sense. Everywhere else bstr structs are passed by value because they're so small. Only when it's supposed to receive a return value they're not.
* vo_opengl: remove pointless NULL-checkwm42016-06-041-1/+1
| | | | It's never NULL.
* vo_opengl: move all icc handling from vo_opengl.c to video.cwm42016-06-033-9/+31
| | | | | | | | | | | | | | | Originally, video.c did not access any CMS things (other than lut3d being set on it), but this has changed. In practice, almost all accesses to it have moved to video.c. vo_opengl only created it, and set the auto icc profile path. Complete the move. Some things wrt. option handling are a bit fishy. (But when is this not the case.) icc-profile-auto was not tested, but the distributed human CI will take care of it.
* vo_opengl: move struct lut3d definitionwm42016-06-033-8/+6
| | | | | This was dumb. Also, lcms.h has actually no need to include video.h besides this and csputils.h (makes it slightly less entangled).
* vo_opengl: fix giant memory leaks with icc profileswm42016-06-031-0/+2
| | | | Well this was dumb.
* vo_opengl: default hdr-tone-mapping to hableNiklas Haas2016-05-301-0/+2
| | | | | | | | | This algorithm works really well. Setting it is a much better "out-of-the-box" experience than just clipping, which will always look ugly. In other words, with this default, users of mpv will just be able to play HDR content without even realizing it's HDR (pretty much).
* vo_opengl: refactor HDR mechanismNiklas Haas2016-05-303-27/+42
| | | | | | | | | | | | | | | | | | | | Instead of doing HDR tone mapping on an ad-hoc basis inside pass_colormanage, the reference peak of an image is now part of the image params (alongside colorspace, gamma, etc.) and tone mapping is done whenever peak_src != peak_dst. To get sensible behavior when mixing HDR and SDR content and displays, target-brightness is a generic filler for "the assumed brightness of SDR content". This gets rid of the weird display_scaled hack, sets the framework for multiple HDR functions with difference reference peaks, and allows us to (in a future commit) autodetect the right source peak from the HDR metadata. (Apart from metadata, the source peak can also be controlled via vf_format. For HDR content this adjusts the overall image brightness, for SDR content it's like simulating a different exposure)
* wayland: implement HIDPI supportRostislav Pehlivanov2016-05-301-3/+8
| | | | | | | | | | | | | | | | | | | | | | | | | The wayland protocol exposes scaling done by the compositor to compensate for small window sizes on small high DPI displays. If the program ignores the scaling done, what'll happen is the compositor is going to ask the program to be scaled down by N times the window size and then it'll upscale the program's surface by N times. The scaling algorithm seems to be bilinear so the scaling is quite obvious. This commit sets up callbacks to listen for the scaling factor of each output and, on rescale events, notifies the compositor that the surface's scale is what the compositor asked for and changes the player's surface to the appropriate size, causing no scaling to be done by the compositor. Compositors not supporting this interface will ignore the callbacks and do nothing, keeping program behaviour the same. For compositors supporting and using this interface (mutter), this will fix the rendering to be pixel precise as it should be. Both the opengl wayland backend and the wayland vo have been fixed to support this. Verified to not break either on weston and mutter. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>
* vo_opengl: add hable tone-mapping algorithmNiklas Haas2016-05-303-0/+13
| | | | | | | | Developed by John Hable for use in Uncharted 2. Also used by Frictional Games in SOMA. Originally inspired by a filmic tone mapping algorithm created by Kodak. From http://frictionalgames.blogspot.de/2012/09/tech-feature-hdr-lightning.html
* vo_opengl: rename tone-mapping=simple to reinhardNiklas Haas2016-05-303-6/+6
| | | | | This is the canonical name for the algorithm. I simply didn't know it before.
* video: remove d3d11 video processor use from OpenGL interopwm42016-05-293-407/+359
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We now have a video filter that uses the d3d11 video processor, so it makes no sense to have one in the VO interop code. The VO uses it for formats not directly supported by ANGLE (so the video data is converted to a RGB texture, which ANGLE can take in). Change this so that the video filter is automatically inserted if needed. Move the code that maps RGB surfaces to its own inteorp backend. Add a bunch of new image formats, which are used to enforce the new constraints, and to automatically insert the filter only when needed. The added vf mechanism to auto-insert the d3d11vpp filter is very dumb and primitive, and will work only for this specific purpose. The format negotiation mechanism in the filter chain is generally not very pretty, and mostly broken as well. (libavfilter has a different mechanism, and these mechanisms don't match well, so vf_lavfi uses some sort of hack. It only works because hwaccel and non-hwaccel formats are strictly separated.) The RGB interop is now only used with older ANGLE versions. The only reason I'm keeping it is because it's relatively isolated (uses only existing mechanisms and adds no new concepts), and because I want to be able to compare the behavior of the old code with the new one for testing. It will be removed eventually. If ANGLE has NV12 interop, P010 is now handled by converting to NV12 with the video processor, instead of converting it to RGB and using the old mechanism to import that as a texture.
* vo_opengl: angle: enable DirectCompositionJames Ross-Gowan2016-05-291-10/+22
| | | | | | This avoids a copy of the video image and lowers vsync jitter. Since there are now two options to add to the window_attribs list, it has been made dynamic.
* vo_opengl: skip junk before first user shader passNiklas Haas2016-05-271-0/+8
| | | | | | | | | | A lot of real-world shaders start off with comments explaining the usage or license, generating lots of "empty" passes. This simply change allows us to skip them, which silences the warning spam and prevents us from having to store and copy around these empty passes. It also adds a more useful failure check: Attempting to use a user shader that doesn't define any passes at all.
* vo_opengl: enable color management on GLESJames Ross-Gowan2016-05-272-3/+8
| | | | | | This requires the GL_EXT_texture_norm16 extension and works in ANGLE. A default precision had to be set for sampler3Ds, otherwise the shaders would fail to compile.
* vo_opengl: fix superxbr shader compilation on ESwm42016-05-261-11/+11
| | | | | ES shaders do not allow implicit conversion from int to float, which is the most annoying ES anti-feature ever.
* hwdec_d3d11egl: call ID3D11DeviceContext::Flushwm42016-05-241-5/+13
| | | | | | | | | This must be called if a texture shared between D3D devices is updated. Often enough, the shared devices will be the same device, but ANGLE forces using shared surfaces. I suppose there is no guarantee the driver will do the expected thing. Internally, the driver could for example not insert the required barriers before the shared texture is used.
* vo_opengl: fix other minor namespace issueswm42016-05-234-11/+11
| | | | See previous commit.
* vo_opengl: rename glUploadTex, drop unused parameterwm42016-05-234-16/+13
| | | | | | | | Rename it to get out of OpenGL's namespace. The gl_ prefix is used by other mpv functions, but no OpenGL ones. The "slice" parameter was never actually used, and all callers passed 0 for it.
* vo_opengl: unify PBO and normal OSD texture upload pathwm42016-05-233-69/+47
| | | | | | | | | | | | | The main change is actually that e first copy to a "staging" memory frame, and then upload this at once. The old non-PBO code called glTexsubImage2D for each OSD sub-bitmap. The new non-PBO code path is a bit faster now if there are many small sub-bitmaps (on Linux/nVidia). It's also a bit simpler, so this is a win. (Although I don't particularly appreciate the mixed normal/PBO texture code.)
* vo_opengl: make ES float texture format checks stricterwm42016-05-234-12/+3
| | | | | | | | | | | | | | | Some of these checks became pointless after dropping ES 2.0 support for extended filtering. GL_EXT_texture_rg is part of core in ES 3.0, and we already check for this version, so testing for the extension is redundant. GL_OES_texture_half_float_linear is also always available, at least as far as our needs go. The functionality we need from GL_EXT_color_buffer_half_float is always available in ES 3.2, and we explicitly check for ES 3.2, so reject this extension if the ES version is new enough.
* vo_opengl: make PBOs work on GLES 3.xwm42016-05-234-10/+24
| | | | | | | | | | | | | For some reason, GLES has no glMapBuffer, only glMapBufferRange. GLES 2 has no buffer mapping at all, and GL 2.1 does not always have glMapBufferRange. On those PBOs remain unsupported (there's no reason to care about GL 2.1 without the extension). This doesn't actually work on ANGLE, and I have no idea why. (There are artifacts on OSD, as if parts of the OSD data weren't copied.) It works on desktop OpenGL and at least 1 other ES 3 implementation. Don't enable it on ANGLE, I guess.
* vo_opengl: remove unused glDrawBufferwm42016-05-232-2/+0
|
* vo_opengl: support framebuffer invalidationwm42016-05-234-0/+26
| | | | | | | | | | Not sure how much can be gained with this, as we can't use it properly yet. For now, this is used only before rendering, which probably does overwhelmingly nothing. In the future, this should be used after temporary passes, which could possibly reduce memory usage and even memory bandwidth usage, depending on the drivers.
* vo_opengl: slightly improve logging of loaded extensionswm42016-05-231-2/+2
| | | | | Only log when actual extensions are loaded, never log anything about builtins.
* vo_opengl: remove non-working rgb/rgba FBO formatswm42016-05-201-3/+1
| | | | | | | | | | | Following commit 84ccebd9, the internal helpers don't allow GL_RGB and GL_RGBA as internal formats for FBO attachments anymore. While OpenGL itself is perfectly fine with it, I don't see much of a reason to bother, and mixing sized and unsized internal formats is confusing anyway. Just remove these formats.
* vo_opengl: require at least ES 3.0 for float textureswm42016-05-191-1/+1
| | | | | | | | | | | | ES 2.0 has this weird rule that not the internalformat parameter determines the internal format, but the combination of all texture parameters. GL_OES_texture_half_float thus does not specify e.g. a GL_RGBA16F format, but requires passing GL_RGBA as format and GL_HALF_FLOAT_OES as type. We won't bother with this, since ES 2.0 is a lost cause anyway. This also removes the OpenGL error when the code is trying to create a f16 FBO for testing whether FBOs work.
* vo_opengl: change error state handling and fix hwdec crashes on errorswm42016-05-191-20/+34
| | | | | | | | | | | | | | | | gl_video_upload_image() can fail in the hardware decoding case. In this case rendering continued "normally", which meant that pass_get_img_tex() would kill the process with an assertion failure. Fix this by allowing gl_video_upload_image() to fail, and exit rendering early enough to skip code which requires an image to be present. (Maybe this is still a bit too subtle, but better than before.) Set an error flag, and render the blue screen we introduced for shader errors. (For this purpose also move the rendering of it to final output, to ensure it's visible at all.) The error flag is temporary, because the associated failure might also be temporary, unlike shader compilation errors.
* vo_opengl: d3d11egl: enable "required" GLSL extensionswm42016-05-193-0/+10
| | | | | | | | ANGLE doesn't handle this very strictly. But if they change this in the future, it shouldn't brick us. Not quite happy with this glsl_extensions fields, but it is quite unintrusive after all.
* vo_opengl: make gl_sc_enable_extension() permanent/idempotentwm42016-05-191-2/+12
| | | | | | | | No reason not to, and makes the following commit slightly simpler. In fact, this makes the shaders more correct too. Normally, "#extension" must come before any normal shader text, including the "precision" directive. Not sure why this worked before. (Probably didn't.)
* vo_opengl: d3d11egl: enable direct nv12 sampling on ES 3.xwm42016-05-191-3/+3
| | | | | | ANGLE was missing texture() overloads in the shader compiler for GL_TEXTURE_EXTERNAL_OES textures. Support has been added upstream, so we can use it now.
* vo_opengl: remove unused field
