* vo_opengl, vo_opengl_cb: drop unneeded vo_frame fieldswm42015-11-041-3/+2
| | | | | | | | | next_vsync/prev_vsync was only used to retrieve the vsync duration. We can get this in a simpler way. This also removes the vsync duration estimation from vo_opengl_cb.c, which is probably worthless anyway. (And once interpolation is made display-sync only, this won't matter at all.)
* vo_opengl: cache frames only in display-sync modewm42015-10-301-1/+3
| | | | | | | vo_frame.num_vsyncs can be != 1 in some cases in normal sync mode too. This is not a very exact fix, but in exchange it's robust. (These vo_frame flags are way too tricky in combination with redrawing and such.)
* vo_opengl: do not attempt to cache frames in FBO in dumb-modewm42015-10-301-1/+1
| | | | | | | | | | There were occasional shader compilation and rendering failures if FBOs were unavailable. This is caused by the FBO caching code getting active, even though FBOs are unavailable (i.e. dumb-mode). Boken by commit 97fc4f. Fixes #2432.
* vo_opengl: remove source shader leftoverBin Jin2015-10-241-2/+0
| | | | The source shader was removed after deband was introduced.
* vo_opengl: always cache to an FBO when not interpolatingNiklas Haas2015-10-231-4/+29
| | | | | | This speeds up redraws considerably (improving eg. <60 Hz material on a 60 Hz monitor with display-sync active, or redraws while paused), but slightly slows down the worst case (eg. video FPS = display FPS).
* vo_opengl: support all kinds of GBRP formatswm42015-10-181-10/+4
| | | | | | | | Adds support for AV_PIX_FMT_GBRP9, AV_PIX_FMT_GBRP10, AV_PIX_FMT_GBRP12, AV_PIX_FMT_GBRP14, AV_PIX_FMT_GBRP16, AV_PIX_FMT_GBRAP, and AV_PIX_FMT_GBRAP16. (Not that it matters, because nobody uses these anyway.)
* vo_opengl: debanding requires GLSL 1.30wm42015-10-011-0/+4
| | | | | | We have to disable it, or shader compilation will fail. Fixes #2362.
* vo_opengl: do not reset video queue when changing video equalizerwm42015-09-301-1/+0
| | | | | | | If interpolation is enabled, then this causes heavy artifacts if done while unpaused. It's preferable to allow a latency of a few frames for the change to take full effect instead. If this is done paused, the frame is fully redrawn anyway.
* vo_opengl: actually set hardware decoder mapped texture formatwm42015-09-241-0/+1
| | | | | | | | | | | Surfaces used by hardware decoding formats can be mapped exactly like a specific software pixel format, e.g. RGBA or NV12. p->image_params is supposed to be set to this format, but it wasn't. (How did this ever work?) Also, setting params->imgfmt in the hwdec interop drivers is pointless and redundant. (Change them to asserts, because why not.)
* vo_opengl: remove sharpen scalers, add sharpen sub-optionwm42015-09-231-6/+8
| | | | | | | | | | | | This turns the old scalers (inherited from MPlayer) into a pre- processing step (after color conversion and before scaling). The code for the "sharpen5" scaler is reused for this. The main reason MPlayer implemented this as scalers was perhaps because FBOs were too expensive, and making it a scaler allowed to implement this in 1 pass. But unsharp masking is not really a scaler, and I would guess the result is more like combining bilinear scaling and unsharp masking.
* vo_opengl: remove unsued chroma_location fieldwm42015-09-231-1/+0
| | | | | This was redundant to forcing the value with vf_format, so the vo_opengl sub-option was removed. This field is just a leftover.
* vo_opengl: move shader file caching to video.cwm42015-09-231-3/+41
| | | | | | It's just about loading and cachign small files, not does not necessarily have anything to do with shaders. Move it to video.c where it's used.
* vo_opengl: fix shader compilation with debanding and OSX hwdecwm42015-09-101-3/+4
| | | | | | 2 things are being stupid here: Apple for requiring rectangle textures with their IOSurface interop for no reason, and OpenGL having a different sampler type for rectangle textures.
* vo_opengl: fix deband sub-option handlingwm42015-09-091-1/+6
| | | | This all has to be done manually.
* vo_opengl: implement debanding (and remove source-shader)Niklas Haas2015-09-091-84/+78
| | | | | | | | | | The removal of source-shader is a side effect, since this effectively replaces it - and the video-reading code has been significantly restructured to make more sense and be more readable. This means users no longer have to constantly download and maintain a separate deband.glsl installation alongside mpv, which was the only real use case for source-shader that we found either way.
* vo_opengl: move self-contained shader routines to a separate fileNiklas Haas2015-09-091-348/+17
| | | | | | | | | | | This is mostly to cut down somewhat on the amount of code bloat in video.c by moving out helper functions (including scaler kernels and color management routines) to a separate file. It would certainly be possible to move out more functions (eg. dithering or CMS code) with some extra effort/refactoring, but this is a start. Signed-off-by: wm4 <wm4@nowhere>
* vo_opengl: reduce code duplication for scaler optionsNiklas Haas2015-09-091-33/+16
| | | | | This simple refactor cuts down on the immense amount of overhead and duplication across all of the related scale-* options.
* vo_opengl: remove gl_ prefixes from files in video/out/openglNiklas Haas2015-09-091-0/+2930
This is a bit redundant with the name of the directory itself, and not in line with existing naming conventions.
