vo_opengl: support new VAAPI EGL interop Should work much better than the old GLX interop code. Requires Mesa 11, and explicitly selecting the X11 EGL backend with: --vo=opengl:backend=x11egl Should it turn out that the new interop works well, we will try to autodetect EGL by default. This code still uses some bad assumptions, like expecting surfaces to be in NV12. (This is probably ok, because virtually all HW will use this format. But we should at least check this on init or so, instead of failing to render an image if our assumption doesn't hold up.) This repo was a lot of help: https://github.com/gbeauchesne/ffvademo The kodi code was also helpful (the magic FourCC it uses for EGL_LINUX_DRM_FOURCC_EXT are nowhere documented, and EGL_IMAGE_INTERNAL_FORMAT_EXT as used in ffvademo does not actually exist). (This is the 3rd VAAPI GL interop that was implemented in this player.)

vo_opengl: D3D11VA + ANGLE interop This uses ID3D11VideoProcessor to convert the video to a RGBA surface, which is then bound to ANGLE. Currently ANGLE does not provide any way to bind nv12 surfaces directly, so this will have to do. ID3D11VideoContext1 would give us slightly more control about the colorspace conversion, though it's still not good, and not available in MinGW headers yet. The video processor is created lazily, because we need to have the coded frame size, of which AVFrame and mp_image have no concept of. Doing the creation lazily is less of a pain than somehow hacking the coded frame size into mp_image. I'm not really sure how ID3D11VideoProcessorInputView is supposed to work. We recreate it on every frame, which is simple and hopefully doesn't affect performance.

vaapi: remove dependency on X11 There are at least 2 ways of using VAAPI without X11 (Wayland, DRM). Remove the X11 requirement from the decoder part and the EGL interop. This will be used by a following commit, which adds Wayland support. The worst about this is the decoder part, which includes a bad hack for using the decoder without any VO interop (also known as "vaapi-copy" mode). Separate the X11 parts so that they're self-contained. For the EGL interop code we do something similar (it's kept slightly simpler, because it essentially only has to translate between our silly MPGetNativeDisplay abstraction and the vaGetDisplay...() call).

client API: expose OpenGL renderer 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

video: remove VDA support VideoToolbox is preferred. Now that FFmpeg released 2.8, there's no reason to support VDA anymore. In fact, we had a bug that made VDA not useable with older FFmpeg versions in some newer mpv releases. VideoToolbox is supported even on slightly older OSX versions, and if not, you still can run mpv without hw decoding.

#if HAVE_VIDEOTOOLBOX_GL
video: fix VideoToolbox/VDA autodetection This affects vo_opengl_cb in particular: it'll most likely auto-load VDA, and then the VideoToolbox decoder won't work. And everything fails. This is mainly caused by FFmpeg using separate pixfmts for the _same_ thing (CVPixelBuffers), simply because libavcodec's architecture demands that hwaccel backends are selected by pixfmts. (Which makes no sense, but now we have the mess.) So instead of duplicating FFmpeg's misdesign, just change the format to our own canonical one on the image output by the decoder. Now the GL interop code is exactly the same for VDA and VT, and we use the VT name only.

The d3d hardware decoders might slightly change behavior: dxva2-copy will not use the VO device anymore if the VO supports proper interop. This pretty much assumes that any in such cases the VO will not use any form of exclusive mode, which makes using the VO device in copy mode unnecessary. This is a big refactor.

For d3d in particular, we drop the mp_d3d_ctx struct completely, and pass the interfaces directly. Remove the emulation checks from vaapi.c and vdpau.c; they are pointless, and the checks that matter are done on the VO layer. The d3d hardware decoders might slightly change behavior: dxva2-copy will not use the VO device anymore if the VO supports proper interop. This pretty much assumes that any in such cases the VO will not use any form of exclusive mode, which makes using the VO device in copy mode unnecessary. This is a big refactor. Some things may be untested and could be broken.

vo_opengl: move hwdec parts into their own files This wasn't done before because there was no advantage in "abstracting" it. This changed, and putting this into its own files is better than messing it into gl_common.c/h.
