* drm/atomic: add connector to atomic contextLongChair2018-05-011-0/+3
| | | | | | | | | | This patch adds - DRM connector object to atomic context. - fd property to the drm atomic object as well as a method to read blob type properties. This allows to ensure that the proper connector is picked up, especially when specifying it from the commandline, and also allows to make sure we're using the right one when embedding with interop into an application.
* client API: add a new way to pass X11 Display etc. to render APIwm42018-03-261-52/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hardware decoding things often need access to additional handles from the windowing system, such as the X11 or Wayland display when using vaapi. The opengl-cb had nothing dedicated for this, and used the weird GL_MP_MPGetNativeDisplay GL extension (which was mpv specific and not officially registered with OpenGL). This was awkward, and a pain due to having to emulate GL context behavior (like needing a TLS variable to store context for the pseudo GL extension function). In addition (and not inherently due to this), we could pass only one resource from mpv builtin context backends to hwdecs. It was also all GL specific. Replace this with a newer mechanism. It works for all RA backends, not just GL. the API user can explicitly pass the objects at init time via mpv_render_context_create(). Multiple resources are naturally possible. The API uses MPV_RENDER_PARAM_* defines, but internally we use strings. This is done for 2 reasons: 1. trying to leave libmpv and internal mechanisms decoupled, 2. not having to add public API for some of the internal resource types (especially D3D/GL interop stuff). To remain sane, drop support for obscure half-working opengl-cb things, like the DRM interop (was missing necessary things), the RPI window thing (nobody used it), and obscure D3D interop things (not needed with ANGLE, others were undocumented). In order not to break ABI and the C API, we don't remove the associated structs from opengl_cb.h. The parts which are still needed (in particular DRM interop) needs to be ported to the render API.
* client API: deprecate opengl-cb API and introduce a replacement APIwm42018-02-281-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | The purpose of the new API is to make it useable with other APIs than OpenGL, especially D3D11 and vulkan. In theory it's now possible to support other vo_gpu backends, as well as backends that don't use the vo_gpu code at all. This also aims to get rid of the dumb mpv_get_sub_api() function. The life cycle of the new mpv_render_context is a bit different from mpv_opengl_cb_context, and you explicitly create/destroy the new context, instead of calling init/uninit on an object returned by mpv_get_sub_api(). In other to make the render API generic, it's annoyingly EGL style, and requires you to pass in API-specific objects to generic functions. This is to avoid explicit objects like the internal ra API has, because that sounds more complicated and annoying for an API that's supposed to never change. The opengl_cb API will continue to exist for a bit longer, but internally there are already a few tradeoffs, like reduced thread-safety. Mostly untested. Seems to work fine with mpc-qt.

* libmpv/opengl_cb.h: mention OpenGL ES 2.0 supportLeo Izen2018-01-141-3/+4
| | | | | opengl_cb.h should mention GLES 2.0 support, since this support is available. Now it does mention it.
* vo_gpu: make it possible to load multiple hwdec interop driverswm42017-12-011-6/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* client API: minor bump + change entry for DRM related opengl-cb changeswm42017-10-231-0/+3
| | | | Commit cfcee4cfe705 forgot those.
* Add DRM_PRIME Format Handling and Display for RockChip MPP decodersLionel CHAZALLON2017-10-231-4/+34
| | | | | | | | | | | This commit allows to use the AV_PIX_FMT_DRM_PRIME newly introduced format in ffmpeg that allows decoders to provide an AVDRMFrameDescriptor struct. That struct holds dmabuf fds and information allowing zerocopy rendering using KMS / DRM Atomic. This has been tested on RockChip ROCK64 device.
* client API: more opengl_cb clarificationswm42017-08-071-4/+7
| | | | Also fix a typo in ra_gl.c. Too greedy for a separate commit.
* vo_opengl: move GL state resetting to vo_opengl_cbwm42017-08-051-0/+3
| | | | | | | | | This code is pretty much for the sake of vo_opengl_cb API users. It resets certain state that either the user or our code doesn't reset correctly. This is somewhat outdated. With GL implicit state being so awfully large, it seems more reasonable require that any code restores the default state when returning to the caller. Some exceptions are defined in opengl_cb.h.
* vo_opengl: drop TLS usagewm42017-05-111-1/+1
| | | | | | | | | | | TLS is a headache. We should avoid it if we can. The involved mechanism is unfortunately entangled with the unfortunate libmpv API for returning pointers to host API objects. This has to be kept until we change the API somehow. Practically untested out of pure laziness. I'm sure I'll get a bunch of reports if it's broken.
* client API: add MPV_ENABLE_DEPRECATED symbolwm42017-04-201-0/+2
| | | | | (Of course this is on by default, because otherwise we'd randomly break downstream applications.)
* Fix use of ISC licensewm42017-04-151-11/+3
| | | | | | | | | | The license text refers a "above copyright notice", so I guess it'd be good to actually provide such a notice. Add the license to some files that were missing it (since in theory, our Copyright file says that such files are LGPL by default). Remove the questionable remarks about the license in the client API.
* client API: update outdated recommendations about window embeddingwm42017-03-021-6/+7
| | | | | | | Basically, the opengl-cb API causes fewer issues, even if it's a bit harder on the API user. See #4197.
* vo_opengl: remove dxva2 dummy hwdec backendwm42017-02-201-20/+3
| | | | | | | | | This was a hack to let libmpv API users pass a d3d device to mpv. It's not needed anymore for 2 reasons: 1. ANGLE does not have this problem 2. Even native GL via nVidia (where this failed) seems to not require this anymore
* vo_opengl: implement videotoolbox hwdec on iOSAman Gupta2017-02-171-0/+1
| | | | | | Implements --hwdec=videotoolbox on iOS. Similar to hwdec_osx.c, but using CVPixelBuffer APIs available on iOS instead of the equivalent IOSurface APIs in macOS.
* client API: adjust opengl_cb hardware decoding commentswm42017-01-261-3/+6
| | | | | | Replace the reprecated --hwdec-preload option. Add a comment about cuvid/cuda decoding.
* vo_opengl: add hw overlay support and use it for RPIwm42016-09-121-0/+23
| | | | | | | | | | | This overlay support specifically skips the OpenGL rendering chain, and uses GL rendering only for OSD/subtitles. This is for devices which don't have performant GL support. hwdec_rpi.c contains code ported from vo_rpi.c. vo_rpi.c is going to be deprecated. I left in the code for uploading sw surfaces (as it might be slightly more efficient for rendering sw decoded video), although it's dead code for now.
* client API: fully document opengl-cb hardware decoding interopwm42016-06-011-3/+40
| | | | | Document it exhaustively. Most of these issues were basically burried in the code.
* vo_opengl_cb: make operation more similar to normal VOswm42015-11-091-1/+5
| | | | | | | | | | | | | | | | | | | | | vo_opengl_cb is a special case, because we somehow have to render video asynchronously, all while "trusting" the API user to do it correctly. This didn't quite work, and a while ago a compromise using a timeout to prevent theoretically possible deadlocks was added. Make it even more synchronous. Basically, go all the way, and synchronize rendering between VO and user renderer thread to the full extent possible. This means the silly frame queue is dropped, and we event attempt to synchronize the GL SwapBuffer call (via mpv_opengl_cb_report_flip()). The changes introduced with commit dc33eb56 are effectively dropped. I don't even remember if they mattered. In the future, we might make all VOs fetch asynchronously from a frame queue, which would mostly remove the differences between vo_opengl and vo_opengl_cb, but this will take a while (if it will even be done).
* vo_opengl: add mechanism to retrieve Display from EGL contextwm42015-09-251-0/+10
| | | | | | | | | | The VAAPI EGL interop code will need access to the X11 Display. While GLX could return it from the current GLX context, EGL has no such mechanism. (At least no standard one supported by all implementations.) So mpv makes up such a mechanism. For internal purposes, this is very rather awkward solution, but it's needed for libmpv anyway.
* client API: rename GL_MP_D3D_interfaceswm42015-09-241-10/+28
| | | | | | | | | | | | | This is a pseudo-OpenGL extension for letting libmpv query native windowing system handles from the API user. (It uses the OpenGL extension mechanism because I'm lazy. In theory it would be nicer to let the user pass them with mpv_opengl_cb_init_gl(), but this would require a more intrusive API change to extend its argument list.) The naming of the extension and associated function was unnecessarily Windows specific (using "D3D"), even though it would work just fine for other platforms. So deprecate the old names and introduce new ones. The old ones still work.
* client API: change subtle wording to different subtle wordingwm42015-08-121-1/+1
| | | | | | | Make a difference between different mpv_handles pointing to the same mpv core, or different mpv cores. While we're not explicit about it, at least avoid that someone could misunderstand when really looking for the case of mpv_handles pointing to the same core.
* client API, dxva2: add a workaround for OpenGL fullscreen issueswm42015-07-031-0/+18
| | | | | | | | | This is basically a hack for drivers which prevent the mpv DXVA2 decoder glue from working if OpenGL is in fullscreen mode. Since it doesn't add any "hard" new API to the client API, some of the code would be required for a true zero-copy hw decoding pipeline, and sine it isn't too much code after all, this is probably acceptable.
* vo_opengl_cb: deprecate mpv_opengl_cb_render()wm42015-04-091-15/+30
| | | | Its vp parameter made no sense anymore. Introduce a new one.
* vo_opengl_cb: add a function to report vsync timewm42015-04-091-0/+12
| | | | | | | And also let vo.c know of it. Currently, this does not help much, but will facilitate future improvements.
* client API: clarify mpv_opengl_cb_render() viewport parameterwm42015-03-091-1/+4
| | | | | | | | | | | | Basically, the idea behind the vp parameter is broken - I guess the intention was to enable rendering to a specific subrectangle of the target framebuffer, but there's nothing to specify the actual target rectangle (the VO will still clear e.g. the borders between video and framebuffer borders). We're not going to keep the current semantics either with the upcoming rework of vo_opengl, so declare this for broken. Maybe we can introduce a function later which does this properly.
* vo_opengl_cb: make mpv_opengl_cb_render() return left framesxylosper2015-01-081-1/+1
| | | | | | Instead of error code which was not helpful because it's always 0, mpv_opengl_cb_render() returns the number of left frames in the frame queue now.
* client API: clarify some vo_opengl_cb requirementswm42015-01-041-0/+6
| | | | Stupid drivers. I hope the problem described here isn't actually common.
* vo_opengl_cb: simplify API uninitializationwm42014-12-311-4/+13
| | | | | | | | | | | Until now, calling mpv_opengl_cb_uninit_gl() at a "bad moment" could make the whole thing to explode. The API user was asked to avoid such situations by calling it only in "good moments". But this was probably a bit too subtle and could easily be overlooked. Integrate the approach the qml example uses directly into the implementation. If the OpenGL context is to be unitialized, forcefully disable video, and block until this is done.
* client API: expose OpenGL rendererwm42014-12-091-0/+199
This adds API to libmpv that lets host applications use the mpv opengl renderer. This is a more flexible (and possibly more portable) option to foreign window embedding (via --wid). This assumes that methods like context sharing and multithreaded OpenGL rendering are infeasible, and that a way is needed to integrate it with an application that uses a single thread to render everything. Add an example that does this with QtQuick/qml. The example is relatively lazy, but still shows how relatively simple the integration is. The FBO indirection could probably be avoided, but would require more work (and would probably lead to worse QtQuick integration, because it would have to ignore transformations like rotation). Because this makes mpv directly use the host application's OpenGL context, there is no platform specific code involved in mpv, except for hw decoding interop. main.qml is derived from some Qt example. The following things are still missing: - a way to do better video timing - expose GL renderer options, allow changing them at runtime - support for color equalizer controls - support for screenshots
