* vf_vapoursynth: fix everythingwm42015-12-201-17/+13
| | | | | | | Broken by commit 0a0bb905. The changes to this filter were accidentally simply not tested, and it was obviously broken in a bunch of ways. Fixes #2616.
* video: switch from using display aspect to sample aspectwm42015-12-1925-166/+109
| | | | | | | | | | | | | | | | MPlayer traditionally always used the display aspect ratio, e.g. 16:9, while FFmpeg uses the sample (aka pixel) aspect ratio. Both have a bunch of advantages and disadvantages. Actually, it seems using sample aspect ratio is generally nicer. The main reason for the change is making mpv closer to how FFmpeg works in order to make life easier. It's also nice that everything uses integer fractions instead of floats now (except --video-aspect option/property). Note that there is at least 1 user-visible change: vf_dsize now does not set the display size, only the display aspect ratio. This is because the image_params d_w/d_h fields did not just set the display aspect, but also the size (except in encoding mode).

* vo_opengl: disable pbo by defaults for opengl-hqwm42015-12-191-1/+0
| | | | Too many problems.
* vo_opengl: handle alpha with odd bit widths toowm42015-12-191-4/+8
| | | | | | | | | | | | | | | Since alpha isn't pulled through the colormatrix (maybe it should?), we reject alpha formats with odd sizes, such as yuva444p10. But the awful tex_mul path in vo_opengl does this anyway (at some points even explicitly), which means there will be a subtle difference in handling of 16 bit yuv alpha formats. Make it consistent and always apply the range adjustment to the alpha component. This also means odd sizes like 10 bit are supported now. This assumes alpha uses the same "shifted" range as the yuv color channels for depths larger than 8 bit. I'm not sure whether this is actually the case.
* vo_opengl: cocoa: output premultiplied alphawm42015-12-193-0/+4
| | | | | Which is apparently what is expected here. (I'm pretty sure X11 compositors want stright alpha, so 2 code paths are needed.)
* vo_opengl: prefix per-backend source files with context_wm42015-12-1911-1/+1

* vo_opengl: split backend code from common.c to context.cwm42015-12-1914-275/+343
| | | | | | | | Now common.c only contains the code for the function loader, while context.c contains the backend loader/dispatcher. Not calling it "backend.c", because the central struct is called MPGLContext.
* vo_opengl: x11egl: retrieve framebuffer depthwm42015-12-193-0/+47
| | | | | | | | | | This is used for dithering, although I'm not aware of anyone who got higher than 8 bit depth support to work on Linux. Also put this into egl_helpers.c. Since EGL is pseudo-portable at best I have no hope that the EGL context creation code in all the backends can be fully shared. But some self-contained functionality can definitely be shared.
* vo_opengl: refactor how framebuffer depth is passed from backendswm42015-12-197-30/+22
| | | | | | | | | | | Store the determined framebuffer depth in struct GL instead of MPGLContext. This means gl_video_set_output_depth() can be removed, and also justifies adding new fields describing framebuffer/backend properties to struct GL instead of having to add more functions just to shovel the information around. Keep in mind that mpgl_load_functions() will wipe struct GL, so the new fields must be set before calling it.
* vo_opengl: cocoa: implement alpha window supportwm42015-12-192-2/+11
| | | | | With --vo=opengl:alpha=yes, the Cocoa backend will now render alpha video without background.
* vo_opengl: fix "win" backend namewm42015-12-191-1/+1
| | | | | | | Although the source file is named w32.c, the backend name was "win" until recently. It was accidentally changed to "w32"; fix it. Fixes #2608 (the manual is correct).
* csputils: update MP_STEREO3D_COUNTPaul B Mahol2015-12-191-1/+1

* vo_opengl: dxinterop: prevent crash after lost deviceJames Ross-Gowan2015-12-141-0/+13
| | | | | | | | | | | When a Direct3D 9Ex device fails to reset, it gets put into the lost state, so set the lost_device flag and don't attempt to present until the device moves out of that state. Failure to recreate the size- dependent objects should set lost_device as well, since we shouldn't try to present in that state. Also, it looks like I was too eager to remove code that sets priv members to NULL and I accidentally removed some that was needed.
* vo_opengl: dxinterop: prevent crash with 0-size windowJames Ross-Gowan2015-12-141-2/+3
| | | | | | Direct3D doesn't like 0-sized swapchain dimensions, even when those dimensions are automatically set. Manually set them to a size that isn't zero instead.
* vo_opengl: enable brightness/contrast controls for RGBwm42015-12-122-9/+14
| | | | | | | | | Why not. Also, instead of disabling hue/saturation for RGB, just don't apply them. (They don't make sense for conversion matrixes other than YUV, but I can't be bothered to keep the fine-grained disabling of UI controls either.)
* vo_opengl: add dxinterop backendJames Ross-Gowan2015-12-114-1/+677
| | | | | | | | | | | | | | | | | | | | | WGL_NV_DX_interop is widely supported by Nvidia and AMD drivers. It allows a texture to be shared between Direct3D and WGL, so that rendering can be done with WGL and presentation can be done with Direct3D. This should allow us to work around some persistent WGL issues, such as dropped frames with some driver/OS combos, drivers that buffer frames to increase performance at the cost of latency, and the inability to disable exclusive fullscreen mode when using WGL to render to a fullscreen window. The addition of a DX_interop backend might also enable some cool Direct3D-specific enhancements in the future, such as using the GetPresentStatistics API to get accurate frame presentation timestamps. Note that due to a driver bug, this backend is currently broken on Intel. It will appear to work as long as the window is not resized too often, but after a few changes of size it will be unable to share the newly created renderbuffer with GL.

* vo_opengl: remove one more XYZ special-casewm42015-12-091-7/+2
| | | | The XYZ colorspace on XYZ pixfmt is enforced in some sanitation routine.
* vo_opengl: fix precision loss of fruit dithering matrixBin Jin2015-12-091-2/+9
| | | | | | | | | | With default setting, the matrix for fruit dithering requires 12 bits precision (values from 0/4096 to 4095/4096). But 16-bit float provides only 10 bits. In addition, when `dither-size-fruit=8` is set, 16 bits are required from the texture format. Fix this by attempting to use 16 bit integer texture first. This is still not precise, but should be better than using a half float.
* csputils: rename "yuv2rgb" functionswm42015-12-095-9/+9
| | | | | | They're not necessarily restricted to YUV aka YCbCr. vo_direct3d.c and demux_disc.c (DVD specific code) changes untested.
* csputils, vo_opengl: remove XYZ special case in color matrix retrievalwm42015-12-093-14/+8
| | | | | This just seems unnecessary. Refactor it a bit. There should be no functional changes.
* csputils: remove obscure int_bits matrix scalingwm42015-12-092-21/+10
| | | | | | | This has no reason to be there. Put the functionality into another function instead. While we're at it, also adjust for possible accuracy issues with high bit depth YUV (matters for rendering subtitles into screenshots only).
* vo_opengl: fix shader compilation regressionwm42015-12-082-4/+5
| | | | | | | | | | The recent LUT adjustment changes broke interpolation. The concatenation of the shader stages is a bit messy, and it seems like sampler_prelude is not a good place to add this macro. Always add the macro to every shader instead. (While this doesn't seem too elegant, this isn't too inelegant either, and goes these problems out of the way.)
* vo_opengl: enable colormatrix even for RGB inputwm42015-12-071-15/+13
| | | | Enables brightness/contrast controls, and handles gbrp10 correctly.
* vo_opengl: fix issues with some obscure pixel formatswm42015-12-075-11/+39
| | | | | | | | | | | | | | | | | | | The computation of the tex_mul variable was broken in multiple ways. This variable is used e.g. by debanding for moving expansion of 10 bit fixed-point input to normalized range to another stage of processing. One obvious bug was that the rgb555 pixel format was broken. This format has component_bits=5, but obviously it's already sampled in normalized range, and does not need expansion. The tex_mul-free code path avoids this by not using the colormatrix. (The code was originally designed to work around dealing with the generally complicated pixel formats by only using the colormatrix in the YUV case.) Another possible bug was with 10 bit input. It expanded the input by bringing the [0,2^10) range to [0,1], and then treating the expanded input as 16 bit input. I didn't bother to check what this actually computed, but it's somewhat likely it was wrong anyway. Now it uses mp_get_csp_mul(), and disables expansion when computing the YUV matrix.
* vo_opengl: decrease default lookup texture size to 64Bin Jin2015-12-071-2/+2
| | | | | | It turns out that with accurate lookup we can decrease the default size of texture now. Do it to compensate the performance loss introduced by the LUT_POS macro.

* vo_opengl: Fix minor LUT sampling errorBin Jin2015-12-073-11/+22
| | | | | | Define a macro to correct the coordinate for lookup texture. Cache the corrected coordinate for 1D filter and use mix() to minimize the performance impact.

* cocoa: fix recent regressionwm42015-12-071-4/+6
| | | | | | | Commit 9db50c67 changed it so that the window title can now be a NULL string. Completely untested. Probably fixes #2570.
* win32: add option to set VO MMCSS profilewm42015-12-061-1/+5
| | | | This was requested.
* vo: get rid of vo_get_window_title()wm42015-12-066-34/+28
| | | | | | | | | | | It always was a weird artifact - VOCTRLs are meant _not_ to require special handling in the code that passes them through (like in vo.c). Removing it is also interesting to further reduce the dependency of backends on struct vo. Just get rid of it. Removing it is somewhat inconvenient, because in many situations the UI window is created after the first VOCTRL_UPDATE_WINDOW_TITLE. This means these backends have to store it in a new field in their own context.
* vd_lavc: fix avctx NULL checkswm42015-12-051-1/+4
| | | | | | If reinit after a fallback from hardware fails, this field can be NULL. The check in control() was broken due to a typo (found by Coverity), and decode() lacked the check entirely.
* vo_opengl_cb: avoid NULL pointer deref in corner caseswm42015-12-051-1/+2
| | | | Found by Coverity.
* vo_opengl: improve boundary check for polar filtersBin Jin2015-12-051-2/+2
| | | | | | | | | If the sampling point is placed diagonally, the radius difference could be as large as sqrt(2.0). And a loosened check with (radius - 1) would potentially include pixels out of the range. Fix the check to handle those corner case properly to avoid unnecessary texture lookup and improve the performance a bit.
* win32: remove dwmapi.dll dynamic loadingwm42015-12-041-34/+5
| | | | All Windows versions we support have this API.
* filter_kernels: remove redundant corner case checkBin Jin2015-12-041-1/+0
| | | | Actually, the original code would bypass some code path below.
* vo_opengl: require --enable-gpl3 for nnediwm42015-12-033-2/+31
| | | | | | | | | There are claims that nnedi3.c doesn't constitute its own new implementation, but is derived from existing HLSL or OpenCL shaders distributed under the LGPLv3 license. Until these are resolved, do the "correct" thing and require --enable-gpl3 to build nnedi.
* video: readd codec delay estimationwm42015-12-023-0/+18
| | | | | | | | | | | | | | | | | Approximately reverts commit 3ccac74d. This failed with some avi files, which do pseudo-VFR by sending packets with empty frames (or repeat frames, depending on point of view). Specifically, these packets are not 0 bytes, so they don't get skipped by libavformat, as with the usual VFR avi hack. Instead, the packet contains a VOP with vop_coded=0, so libavcodec will just return no frame. We could probably distinguish such skipped frames and delayed frames by explicitly measuring the codec delay by counting how long it takes to get the very first frame (and then treat skips as explicit drops), but we may as well simply reinstate the old code. To appease to at least one semi-broken case, do not enable this logic on the RPI, as the FFmpeg MMAL wrapper has arbitrary buffering (and MMAL itself is asynchronous).
* vo_opengl: fix backend=x11 on Intelwm42015-12-021-1/+1
| | | | "backend=x11" was resolved to x11_probe, which is unintentional.
* vo_opengl: add credits to NNEDI3 shaderBin Jin2015-12-021-0/+16
| | | | Add credits to several existing implementation of NNEDI3 shader.
* vo_opengl: enable NNEDI3 prescaler on OpenGL ES 3.0Bin Jin2015-12-023-14/+19
| | | | | | | | | | | | | | It turns out that both UBO and intBitsToFloat() are supported in OpenGL ES 3.0[1][2], enable them so that NNEDI3 prescaler can be used in a wider range of backends. Also fixes some implicit int-to-float conversions so that the shader actually compiles on GLES. Tested on Linux desktop (nvidia 358.16) with "es" sub-option.

* vo_opengl_cb: pass mpv_global to gl_videowm42015-11-301-1/+1
| | | | | | | | I guess gl_video->global was originally meant to be optional, but now it crashes in some newer code with vo_opengl_cb, which tries to init it with this field set to NULL (because normally it's not needed). Probably fixes #2542.
* vo: cosmetics: split functionwm42015-11-291-41/+56
| | | | | Split two huge chunks from the update_vsync_timing_after_swap() function. There should be no functional changes.
* vo: make using estimated FPS more conservativewm42015-11-291-0/+6
| | | | | | | | | | Don't use the average FPS if there are likely skipped vsyncs. Note that we don't use the normal skip detection, as it is unreliable if the real and assumed display FPS differ too much. The normal skip detection is still in place as it's more reliable in the case when vsync jitters much, but the display FPS is relatively exact. Further improvement over commit 41f2c653.
* vo: remove redundant and broken codewm42015-11-291-2/+0
| | | | This was stupid.
* vo_opengl: make tscale=mitchell:tscale-clamp the defaultwm42015-11-291-2/+4
| | | | Looks better than "oversample". tscale-clamp suggested by haasn.
* vo_opengl: warn if interpolation is enabled, but not display-syncwm42015-11-281-0/+10
| | | | | | | Try to avoid user confusion. Reading the global options in this place is a pretty disgusting hack, but it's still the most robust way.
* vo: report when switching back to system-reported FPS toowm42015-11-281-4/+11
| | | | | | Instead of just when switching away from it. Further improvement over commit 41f2c653.
* vo: wait longer before abandoning system-reported display-fpswm42015-11-281-1/+4
| | | | Further improvement over commit 41f2c653.
* vo_opengl: fix interpolation with display-syncwm42015-11-282-12/+9
| | | | | | | | | | | | | | | | | | | | At least I hope so. Deriving the duration from the pts was not really correct. It doesn't include speed adjustments, and becomes completely wrong of the user e.g. changes the playback speed by a huge amount. Pass through the accurate duration value by adding a new vo_frame field. The value for vsync_offset was not correct either. We don't need the error for the next frame, but the error for the current one. This wasn't noticed because it makes no difference in symmetric cases, like 24 fps on 60 Hz. I'm still not entirely confident in the correctness of this, but it sure is an improvement. Also, remove the MP_STATS() calls - they're not really useful to debug anything anymore.
* vo: change vo_frame field unitswm42015-11-273-9/+6
| | | | | | | This was just converting back and forth between int64_t/microseconds and double/seconds. Remove this stupidity. The pts/duration fields are still in microseconds, but they have no meaning in the display-sync case (also drop printing the pts field from opengl/video.c - it's always 0).
* vo: switch back to system-reported display FPS if possiblewm42015-11-271-8/+10
| | | | | | If we switched away from the system FPS, we were remaining in this mode ssentially forever. There's no reason to do so; switch back if the estimated FPS gets worse again. Improvement over commit 41f2c653.
* vo: factor redundant timer callswm42015-11-271-3/+4
| | | | Call it once instead of 3 times.
* vo: fix audio-timing framedrop regressionswm42015-11-271-4/+5
| | | | | | | | | | | | | | Commit 12eb8b2d accidentally disabled framedropping in the audio timing case. It tried to replace the last_flip field with the prev_vsync one, which didn't work because prev_sync is reset to 0 if the timing code is used. Fix it by always setting it properly. This field must (or should) be reinitialized to something sensible when switching to display sync timing mode; since prev_vsync is not reset anymore, the check when to reinitialize this field has to be adjusted as well. It's a bit weird that update_vsync_timing_after_swap() now does some minor work for timing mode too, but I guess it's ok, if only to avoid additional fields and timer calls.
* vo: disregard system-reported display FPS if it's too imprecisewm42015-11-271-13/+42
| | | | | | | | | | | | If the system-reported display FPS (returned by the VO backends, or forced with --display-fps) is too imprecise (deviating frame duration by more than 1%). This works if the display FPS is off by almost 1 (typical for old/bad/broken OS APIs). Actually it even works if the FPs is completely wrong. Is it a good idea? Probably not. It might be better to only output a warning message. But unless there are reports about it going terribly wrong, I'll go with this for now.
* vo: improve vsync delay detectionwm42015-11-271-9/+15
| | | | | | | Actually I'm not content with the detection added in commit 44376d2d. It triggers too often if vsync is very jittery. It's easy to avoid this: we add more samples to the detection by reusing the drift computation loop. If there's a significant step in the drift, we consider it a drop.
* w32_common: implement icc-profile-autoJames Ross-Gowan2015-11-261-7/+50
| | | | | | | | | | | | This adds basic support for ICC profiles. Per-monitor profiles are supported. WCS profiles are not supported, but there is an API for converting WCS profiles to ICC, so they might be supported in future. I'm just not sure if anyone actually uses them. Reloading the ICC profile when it's changed in the control panel is also not supported. This might be possible by using the WCS APIs and watching the registry for changes, but there is no official API for it, and as far as I can tell, no other Windows programs can do it.
* vo: smooth out reported vsync timewm42015-11-251-18/+23
| | | | | | | | | | Return the estimated/ideal flip time to the timing logic (meaning vo_get_delay() returns a smoothed out time). In addition to this add some lame but working drift compensation. (Useful especially if the display FPS is wrong by a factor such as 1.001.) Also remove some older leftovers. The vsync_i
