* vo_gpu: fix mobius tone mapping compatibility to GLSL 120wm42017-11-031-1/+1
| | | | | | | | | Normally such code is didsabled by have_mglsl==false in check_gl_features(), but apparently not this one. Just fix it. Seems also more readable. Fixes #5069.
* vo_gpu: change --tone-mapping-desaturate algorithmNiklas Haas2017-10-251-8/+10
| | | | | | | | | | | | | | | 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.
* vo_gpu: attempt to avoid UBOs for dynamic variablesNiklas Haas2017-09-261-0/+1
| | | | | | | | | 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: drop the RA_CAP_NESTED_ARRAY req from EWA computeNiklas Haas2017-09-211-25/+23
| | | | | | | | | | 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_opengl: refactor into vo_gpuNiklas Haas2017-09-211-0/+872
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.
