* msg: reinterpret a bunch of message levelsNiklas Haas2017-12-151-21/+13
| | | | | | | | | | | | | | | | | | | | | | I've decided that MP_TRACE means “noisy spam per frame”, whereas MP_DBG just means “more verbose debugging messages than MSGL_V”. Basically, MSGL_DBG shouldn't create spam per frame like it currently does, and MSGL_V should make sense to the end-user and provide mostly additional informational output. MP_DBG is basically what I want to make the new default for --log-file, so the cut-off point for MP_DBG is if we probably want to know if for debugging purposes but the user most likely doesn't care about on the terminal. Also, the debug callbacks for libass and ffmpeg got bumped in their verbosity levels slightly, because being external components they're a bit less relevant to mpv debugging, and a bit too over-eager in what they consider to be relevant information. I exclusively used the "try it on my machine and remove messages from MSGL_* until it does what I want it to" approach of refactoring, so YMMV.
* video: remove code duplication by calling a hwdec loader helperwm42017-12-111-2/+1
| | | | | Make gl_video_load_hwdecs() call gl_video_load_hwdecs_all() when all HW decoders should be loaded.
* video: properly initialize and set hwdec_interopwm42017-12-111-0/+2
| | | | Don't reset --gpu-hwdec-interop if vo_gpu uses dumb mode.
* vo_gpu: make it possible to load multiple hwdec interop driverswm42017-12-011-21/+82
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make the VO<->decoder interface capable of supporting multiple hwdec APIs at once. The main gain is that this simplifies autoprobing a lot. Before this change, it could happen that the VO loaded the "wrong" hwdec API, and the decoder was stuck with the choice (breaking hw decoding). With the change applied, the VO simply loads all available APIs, so autoprobing trickery is left entirely to the decoder. In the past, we were quite careful about not accidentally loading the wrong interop drivers. This was in part to make sure autoprobing works, but also because libva had this obnoxious bug of dumping garbage to stderr when using the API. libva was fixed, so this is not a problem anymore. The --opengl-hwdec-interop option is changed in various ways (again...), and renamed to --gpu-hwdec-interop. It does not have much use anymore, other than debugging. It's notable that the order in the hwdec interop array ra_hwdec_drivers[] still matters if multiple drivers support the same image formats, so the option can explicitly force one, if that should ever be necessary, or more likely, for debugging. One example are the ra_hwdec_d3d11egl and ra_hwdec_d3d11eglrgb drivers, which both support d3d11 input. vo_gpu now always loads the interop lazily by default, but when it does, it loads them all. vo_opengl_cb now always loads them when the GL context handle is initialized. I don't expect that this causes any problems. It's now possible to do things like changing between vdpau and nvdec decoding at runtime. This is also preparation for cleaning up vd_lavc.c hwdec autoprobing. It's another reason why hwdec_devices_request_all() does not take a hwdec type anymore.
* vo_gpu: never pass flipped images to ra or ra backendswm42017-11-101-2/+7
| | | | | | | | | | | | | | | | | | | Seems like the last refactor to this code broke playing flipped images, at least with --opengl-pbo --gpu-api=opengl. Flipping is rather a shitmess. The main problem is that OpenGL does not support flipped uploading. The original vo_gl implementation considered it important to handle the flipped case efficiently, so instead of uploading the image line by line backwards, it uploaded it flipped, and then flipped it in the renderer (basically the upload path ignored the flipping). The ra code and backends probably have an insane and inconsistent mix of semantics, so fix this by never passing it flipped images in the first place. In the future, the backends should probably support flipped images directly. Fixes #5097.
* vo_gpu: d3d11: add RA caps for ra_d3d11James Ross-Gowan2017-11-071-1/+15
| | | | | | | | | | | | | | | | ra_d3d11 uses the SPIR-V compiler to translate GLSL to SPIR-V, which is then translated to HLSL. This means it always exposes the same GLSL version that the SPIR-V compiler supports (4.50 for shaderc/glslang.) Despite claiming to support GLSL 4.50, some features that are tied to the GLSL version in OpenGL are not supported by ra_d3d11 when targeting legacy Direct3D feature levels. This includes two features that mpv relies on: - Reading from gl_FragCoord in the fragment shader (requires FL 10_0) - textureGather from any texture component (requires FL 11_0) These features have been exposed as new RA caps.
* vo_gpu: don't re-render hwdec frames when repeating frameswm42017-11-031-19/+11
| | | | | | | | | | | | | Repeating frames (for display-sync) is not supposed to render the entire frame again. When using hardware decoding, it unfortunately did: the renderer uses the frame ID to check whether the frame data changed, and unmapping the hwdec frame clears it. Essentially reverts commit 761eeacf5407cab07. Back then I probably thought it would be a good idea to release the hwdec image quickly in order to return it to the decoder, but they're referenced anyway. This should increase the performance and reduce GPU work.
* vo_gpu: change --tone-mapping-desaturate algorithmNiklas Haas2017-10-251-1/+1
| | | | | | | | | | | | | | | Comparing mpv's implementation against the ACES ODR reference samples and algorithms, it seems like they're happy desaturating highlights _way_ more aggressively than mpv currently does. And indeed, looking at some example clips like The Redwoods (which is actually well-mastered), the current desaturation produces unnatural-looking brightness fringes where the sky meets the treeline. Adjust the algorithm to make it apply to a much larger, more gradual brightness region; and change the interpretation of the parameter. As a bonus, the new parameter is actually sanely scaled (higher values = more desaturation). Also, make it scale based on the signal level instead of the luminance, to avoid under-desaturating bright blues.
* video: fix alpha handlingwm42017-10-191-2/+4
| | | | | | | | | Regression since ec6e8a31e092a1d. Removal of the explicit else case always applies the conversion to premultiplied alpha in the else branch. We want to scale with multiplied alpha, but we don't want to multiply with alpha again on top of it. Fixes #4983, hopefully.
* vo_gpu: add rgba16hf to the list of FBO formatsJames Ross-Gowan2017-10-181-1/+2
| | | | | | | This should be functionally identical to rgba16f, since the formats only differ in their representation on the CPU, but it could be useful for RA backends that don't expose rgba16f, like Vulkan. It's definitely useful for the WIP D3D11 backend.
* vo_gpu: fix video sometimes not being rerendered on equalizer changewm42017-10-171-1/+9
| | | | | | | | | | | | | | With video paused, changing the brightness controls (or similar) would sometimes not rerender the video frame. So the OSD would redraw, but the video wouldn't change. This is caused by output caching, and a redraw request is free to return the cached frame. Change it such to invalidate the cached frame if any of the options or the equalizer change. In theory, gl_video_reset_surfaces() could be called if the equalizer changes - this would apparently force interpolatzion to redraw all frames. But this looks kind of crappy when changing the equalizer during playback. It'll "eventually" use the correct settings anyway, and when paused interpolation is off.
* vo_gpu: enable 3DLUTs in dumb modeNiklas Haas2017-09-301-1/+3
| | | | | | Unless FBOs are unsupported, this works. In particular, it's required to get ICC profiles working in voluntary dumb mode. So instead of blanket-disabling it, only disable it in the !have_fbo false case.
* vo_gpu: fix --opengl-gamma redirectNiklas Haas2017-09-281-1/+1
| | | | | It still pointed at --gpu-gamma, but we decided on --gamma-factor instead.
* vo_gpu: set the correct number of vertex attribsNiklas Haas2017-09-281-2/+2
| | | | | | | This was always set to the length of the VAO, but it should have been set to the number of vertex attribs actually in use for this frame. No idea how that managed to survive the test framework on nvidia/linux, but ANGLE caught it.
* vo_gpu: make the vertex attribs dynamicNiklas Haas2017-09-281-53/+71
| | | | | | | | | | | | | | | | This has several advantages: 1. no more redundant texcoords when we don't need them 2. no more arbitrary limit on how many textures we can bind 3. (that extends to user shaders as well) 4. no more arbitrary limits on tscale radius To realize this, the VAO was moved from a hacky stateful approach (gl_sc_set_vertex_attribs) - which always bothered me since it was required for compute shaders as well even though they ignored it - to be a proper parameter of gl_sc_dispatch_draw, and internally plumbed into gl_sc_generate, which will make a (properly mangled) deep copy into params.vertex_attribs.
* vo_gpu: kill some static arraysNiklas Haas2017-09-281-81/+69
| | | | | This gets rid of the hard-coded limits on the number of hooks, textures and hook points.
* vo_gpu: attempt to avoid UBOs for dynamic variablesNiklas Haas2017-09-261-0/+5
| | | | | | | | | This makes the radeon driver shut up about frequently updating STATIC_DRAW UBOs (--opengl-debug), and also reduces the amount of synchronization necessary for vulkan uniform buffers. Also add some extra debugging/tracing code paths. I went with a flags-based approach in case we ever want to extend this.
* vo_gpu: handle texture initialization errors gracefullyNiklas Haas2017-09-231-15/+22
| | | | | | | | | | Tested by making the ra_tex_resize function always fail (apart from the initial FBO check). This required a few changes: 1. reset shaders on failed dispatch 2. reset cleanup binds on failed dispatch 3. fall back to initializing the struct image to 1x1 on failure 4. handle output_fbo_valid gracefully
* vo_gpu: reduce the --alpha=blend-tiles checkerboard intensityNiklas Haas2017-09-221-1/+1
| | | | | | | | This was sort of grating by default and made it really hard to actually read e.g. text on top of a transparent background. I decided to approach the problem from both directions, making the whites darker and the grays lighter. This brings it closer to the dynamic range of e.g. the wikipedia transparent svg preview.
* vo_gpu: simplify compute shader coordinate calculationNiklas Haas2017-09-221-5/+2
| | | | Since the removal of FBOTEX_FUZZY, this can be made slightly simpler.
* vo_gpu: simplify structs / namesNiklas Haas2017-09-221-284/+285
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to the plethora of historical baggage from different eras getting confusing, I decided to simplify and unify the struct organization and naming scheme. Structs that got renamed: 1. fbodst -> ra_fbo (and moved to gpu/context.h) 2. fbotex -> removed (redundant after 2af2fa7a) 3. fbosurface -> surface 4. img_tex -> image In addition to these structs being renamed, all of the names have been made consistent. The new scheme is as follows: struct image img; struct ra_tex *tex; struct ra_fbo fbo; This also affects derived names, e.g. indirect_fbo -> indirect_tex. Notably also, finish_pass_fbo -> finish_pass_tex and finish_pass_direct -> finish_pass_fbo. The new equivalent of fbotex_change() is called ra_tex_resize(). This commit (should) contain no logic changes, just renaming a bunch of crap.
* vo_gpu: kill off FBOTEX_FUZZYNiklas Haas2017-09-221-18/+16
| | | | | | | | | | I've observed the garbage pixels in more scenarios. They also were never really needed to begin with, originally being a discovered work-around for bug that we fixed since then anyway. Doesn't really seem to even help resizing, since the OpenGL drivers are all smart enough to pool resources internally anyway. Fixes #1814
* options: properly handle deprecated options with CLI actionswm42017-09-221-1/+1
| | | | | | | | We want e.g. --opengl-shaders-append=foo to resolve to the new option, all while printing an option name. --opengl-shader is a similar case. These options are special, because they apply "actions" on actual options by specifying a suffix. So the alias/deprecation handling has to be part of resolving the actual option from prefix and suffix.
* vo_gpu: drop the RA_CAP_NESTED_ARRAY req from EWA computeNiklas Haas2017-09-211-1/+1
| | | | | | | | | | Almost as fast as the old code, but more general. Notably, glslang doesn't support nested arrays. (cf. https://github.com/KhronosGroup/glslang/issues/1057) Also much cleaner code-wise, so I think I'll keep it even if glslang implements array_of_arrays.
* vo_gpu: fix gamma scaleNiklas Haas2017-09-211-3/+3
| | | | | | This never really made sense since the BT.1886 changes. It should get *brighter* for bright rooms, not darker for dark rooms. Picked some new values that seemed reasonable-ish.
* vo_gpu: describe the plane merging passNiklas Haas2017-09-211-1/+1
| | | | This can get left unknown if something hooks NATIVE
* vo_opengl: refactor into vo_gpuNiklas Haas2017-09-211-0/+3809
This is done in several steps: 1. refactor MPGLContext -> struct ra_ctx 2. move GL-specific stuff in vo_opengl into opengl/context.c 3. generalize context creation to support other APIs, and add --gpu-api 4. rename all of the --opengl- options that are no longer opengl-specific 5. move all of the stuff from opengl/* that isn't GL-specific into gpu/ (note: opengl/gl_utils.h became opengl/utils.h) 6. rename vo_opengl to vo_gpu 7. to handle window screenshots, the short-term approach was to just add it to ra_swchain_fns. Long term (and for vulkan) this has to be moved to ra itself (and vo_gpu altered to compensate), but this was a stop-gap measure to prevent this commit from getting too big 8. move ra->fns->flush to ra_gl_ctx instead 9. some other minor changes that I've probably already forgotten Note: This is one half of a major refactor, the other half of which is provided by rossy's following commit. This commit enables support for all linux platforms, while his version enables support for all non-linux platforms. Note 2: vo_opengl_cb.c also re-uses ra_gl_ctx so it benefits from the --opengl- options like --opengl-early-flush, --opengl-finish etc. Should be a strict superset of the old functionality. Disclaimer: Since I have no way of compiling mpv on all platforms, some of these ports were done blindly. Specifically, the blind ports included context_mali_fbdev.c and context_rpi.c. Since they're both based on egl_helpers, the port should have gone smoothly without any major changes required. But if somebody complains about a compile error on those platforms (assuming anybody actually uses them), you know where to complain.
