* Add more constwm42014-06-111-1/+1
| | | | | | | While I'm not very fond of "const", it's important for declarations (it decides whether a symbol is emitted in a read-only or read/write section). Fix all these cases, so we have writeable global data only when we really need.
* gl_x11: always require some GLX API functions, avoid dlsym()wm42014-05-311-2/+0
| | | | | | | | | | | | | | The functions glXGetProcAddressARB() and glXQueryExtensionsString() were loaded using dlsym(). This could fail when compiling to libmpv, because then dlopen(NULL, ...) will look in the main program's list of libraries, and the libGL linked to libmpv is never considered. (Don't know if this somehow could be worked around.) The result is that using vo_opengl with libmpv can fail. Avoid this by not using dlsym(). glXGetProcAddressARB() was already used directly in the same file, and that never caused any problems. (Still add it to the configure test.) glXQueryExtensionsString() is documented as added in GLX 1.1 - that's ancient.
* video/out: remove unused config() parameterswm42014-05-071-4/+2
| | | | This was cleaned up yesterday.
* m_option: add mp_log callback to OPT_STRING_VALIDATE optionswm42013-12-211-2/+2
| | | | | And also convert a bunch of other code, especially ao_wasapi and ao_portaudio.

* gl_video: change internal API for hwdec mp_image downloadStefano Pigozzi2013-12-021-1/+2
| | | | | | Previous API worked under the assumption that download_image is always called after map_image. In practice this is true, but it's better to have a much generic API that doesn't depend on the order in which the functions are called.
* vo_opengl: support for vda hardware decodingStefano Pigozzi2013-12-021-0/+2
| | | | | | | | | | | The harder work was done in the previous commits. After that this feature comes out almost for free. The only problem is I can't get the textures created with CGLTexImageIOSurface2D to download properly, thus the code performs download using some CoreVideo APIs. If someone knows why download of textures created with CGLTexImageIOSurface2D doesn't work please contact me :)
* gl_video: support packed YUV formats with Apple extensionsStefano Pigozzi2013-12-021-0/+1
| | | | | | | | | | This adds support for packed YUV formats (YUVY and UYVY) using the extension GL_APPLE_rgb_422. While supporting this formats on their own is not that important (considering most video is planar YUV) they are used for interoperability with IOSurfaces. Next commit will use this formats to render VDA hardware decoded frames through IOSurface and OpenGL interoperability.
* vo_opengl: add support for rectangle textureswm42013-12-011-0/+3
| | | | | | | | | This allows vo_opengl to use GL_TEXTURE_RECTANGLE textures, either by enabling it with the 'rectangle-textures' sub-option, or by having a hwdec backend force it. By default it's off. The _only_ reason we're adding this is because VDA can export rectangle textures only.
* gl_hwdec: use a imgfmt field instead of a query_format callbackwm42013-11-291-2/+2
| | | | | Now that vdpau always uses a single image format, this can be simplified.
* gl_common: remove unneeded callbackwm42013-11-141-1/+0
| | | | We got rid of this some time ago, but apparently not completely.
* vo_opengl: fix alpha values written to the framebufferwm42013-11-101-0/+1
| | | | | | | | | | | | | | | | | | | | | | | When blending OSD and subtitles onto the video, we write bogus alpha values. This doesn't normally matter, because these values are normally unused and discarded. But at least on Wayland, the alpha values are used by the compositor and leads to transparent windows even with opaque video on places where the OSD happens to use transparency. (Also see github issue #338.) Until now, the alpha basically contained garbage. The source factor GL_SRC_ALPHA meant that alpha was multiplied with itself. Use GL_ONE instead (which is why we have to use glBlendFuncSeparate()). This should give correct results, even with video that has alpha. (Or at least it's something close to correct, I haven't thought too hard how the compositor will blend it, and in fact I couldn't manage to test it.) If glBlendFuncSeparate() is not available, fall back to glBlendFunc(), which does the same as the code did before this commit. Technically, we support GL 1.1, but glBlendFuncSeparate is 1.4, and I guess we should try not to crash if vo_opengl_old runs on a system with GL 1.1 drivers only.
* vo_opengl: support for vdpau hardware decodingwm42013-11-051-0/+10
| | | | | | | | | | | | This uses vdpau OpenGL interop to convert a vdpau surface to a texture. Note that this is a bit weak and primitive. Deinterlacing (or any other form of vdpau postprocessing) is not supported. vo_opengl chroma scaling and chroma sample position are not supported. Internally, the vdpau video surfaces are converted to a RGBA surface first, because using the video surfaces directly is too complicated. (These surfaces are always split into separate fields, and the vo_opengl core expects progressive frames or frames with weaved fields.)
* vo_opengl: redo aspects of initialization, change hwdec APIwm42013-11-051-7/+7
| | | | | | | | | | | Instead of checking for resolution and image format changes, always fully reinit on any parameter change. Let init_video do all required initializations, which simplifies things a little bit. Change the gl_video/hardware decoding interop API slightly, so that hwdec initialization gets the full image parameters. Also make some cosmetic changes.

|\ | | | | | | | | Conflicts: configure
| * vo_opengl: add support for VA-API OpenGL interopwm42013-11-041-0/+1
| | | | | | | | | | | | | | | | VA-API's OpenGL/GLX interop is pretty bad and perhaps slow (renders a X11 pixmap into a FBO, and has to go over X11, probably involves one or more copies), and this code serves more as an example, rather than for serious use. On the other hand, this might be work much better than vo_vaapi, even if slightly slower.
| * vo_opengl: add infrastructure for hardware decoding OpenGL interopwm42013-11-041-0/+38
| | | | | | | | | | | | | | | | | | | | | | | | Most hardware decoding APIs provide some OpenGL interop. This allows using vo_opengl, without having to read the video data back from GPU. This requires adding a backend for each hardware decoding API. (Each backend is an entry in gl_hwdec_vaglx[].) The backends expose video data as a set of OpenGL textures. Add infrastructure to support this. The next commit will add support for VA-API.
* | configure: uniform the defines to #define HAVE_xxx (0|1)Stefano Pigozzi2013-11-031-1/+1
|/ | | | | | | | | | | | | | | | | | | | | The configure followed 5 different convetions of defines because the next guy always wanted to introduce a new better way to uniform it[1]. For an hypothetic feature 'hurr' you could have had: * #define HAVE_HURR 1 / #undef HAVE_DURR * #define HAVE_HURR / #undef HAVE_DURR * #define CONFIG_HURR 1 / #undef CONFIG_DURR * #define HAVE_HURR 1 / #define HAVE_DURR 0 * #define CONFIG_HURR 1 / #define CONFIG_DURR 0 All is now uniform and uses: * #define HAVE_HURR 1 * #define HAVE_DURR 0 We like definining to 0 as opposed to `undef` bcause it can help spot typos and is very helpful when doing big reorganizations in the code.

* gl_common: osx: fix compilation with latest XQuartz RCStefano Pigozzi2013-10-301-1/+1
| | | | Looks the gl.h header in XQuartz is incompatible with the one in OS X 10.9.
* gl_common: complete mp_msg conversionwm42013-09-121-2/+2

* core: move contents to mpvcore (2/2)Stefano Pigozzi2013-08-061-2/+2
| | | | Followup commit. Fixes all the files references.
* video/out: use new mp_msg stuff for vo.c and vo_openglwm42013-07-311-2/+2

* gl_video: improve ditheringwm42013-05-261-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Use a different algorithm to generate the dithering matrix. This looks much better than the previous ordered dither matrix with its cross-hatch artifacts. The matrix generation algorithm as well as its implementation was contributed by Wessel Dankers aka Fruit. The code in dither.c is his implementation, reformatted and with static global variables removed by me. The new matrix is uploaded as float texture - before this commit, it was a normal integer fixed point matrix. This means dithering will be disabled on systems without float textures. The size of the dithering matrix can be configured, as the matrix is generated at runtime. The generation of the matrix can take rather long, and is already unacceptable with size 8. The default is at 6, which takes about 100 ms on a Core2 Duo system with dither.c compiled at -O2, which I consider just about acceptable. The old ordered dithering is still available and can be selected by putting the dither=ordered sub-option. The ordered dither matrix generation code was moved to dither.c. This function was originally written by Uoti Urpala.
* video/out: introduce vo_control for gl_common based VOswm42013-05-261-8/+1
| | | | | | | | | | | | | | | | Instead of having separate callbacks for each backend-handled feature (like MPGLContext.fullscreen, MPGLContext.border, etc.), pass the VOCTRL responsible for this directly to the backend. This allows removing a bunch of callbacks, that currently must be set even for optional/lesser features (like VOCTRL_BORDER). This requires changes to all VOs using gl_common, as well as all backends that support gl_common. Also introduce VOCTRL_CHECK_EVENTS. vo.check_events is now optional. VO backends can use VOCTRL_CHECK_EVENTS instead to implementing check_events. This has the advantage that the event handling code in VOs doesn't have to be duplicated if vo_control() is used.
* OSX: run native event loop in a separate threadStefano Pigozzi2013-05-121-0/+7
| | | | | | | | | | | | | | This commit is a followup on the previous one and uses a solution I like more since it totally decouples the Cocoa code from mpv's core and tries to emulate a generic Cocoa application's lifecycle as much as possible without fighting the framework. mpv's main is executed in a pthread while the main thread runs the native cocoa event loop. All of the thread safety is mainly accomplished with additional logic in cocoa_common as to not increase complexity on the crossplatform parts of the code.
* gl_common: add some sort of locking APIwm42013-05-121-0/+8
| | | | | | | | | Some OpenGL implementations on some platforms require that a context is current only on one thread. For this reason, mpgl_lock() and mpgl_unlock() take care of this as well for convenience. Each backend that needs thread safety should provide it's own locking strategy inside of `set_current`.
* gl_common: split into platform specific fileswm42013-03-281-12/+13
| | | | | | | | | | | Do this instead of stuffing all x11/cocoa/win32/wayland specific code into gl_common.c. The cocoa specific parts could probably go directly into cocoa_common.m, possibly same with wayland. Also redo how the list of backends is managed. Get rid of the GLTYPE_ constants. Instead of having a big switch() on GLTYPE_, each backend entry has a function pointer to setup the MPGLContext callback (e.g. mpgl_set_backend_x11()).
* gl_common: get rid of symbol redefinition warnings with recent Mesawm42013-03-031-0/+1
| | | | | | | | | | | | | Apparently newer Mesa versions changed their <GL/glx.h> header, and unconditionally define GLX_CONTEXT_MAJOR_VERSION_ARB and others. This clashed with gl_header_fixes.h, a header which quarantines bad hacks to make compilation possible on systems with outdated GL headers. Specifically, our header was included before glx.h, so the hacks were always active, and somehow Mesa's glx.h used to deal with this by not redefining existing identifiers. Fix the gl_header_fixes.h logic so the hacks are checked after including glx.h.
* vo_opengl: don't destroy VOFLAG_HIDDEN windowwm42013-03-031-5/+0
| | | | | | | This was done so because the X11 code had a hard to track down issue with some window managers, and caused the VO window to be placed incorrectly. This was fixed in the previous commit. Consequently, we can remove this bad hack.
* wayland: add wayland supportAlexander Preisinger2013-02-281-0/+1
| | | | | | | | | | | | | | | | | | | | | All wayland only specific routines are placed in wayland_common. This makes it easier to write other video outputs. The EGL specific parts, as well as opengl context creation, are in gl_common. This backend works for: * opengl-old * opengl * opengl-hq To use it just specify the opengl backend --vo=opengl:backend=wayland or disable the x11 build. Don't forget to set EGL_PLATFORM to wayland.

* video/out: rename create_window to config_windowwm42013-02-261-4/+4
| | | | | | create_window is really bad naming, because this function can be called multiple times, while the name implies that it always creates a new window. At least the name config_window is not actively misleading.
* gl_common: simplify window/context creationwm42013-02-261-11/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow the backend code to create a GL context on best effort basis, instead of having to implement separate functions for each variation. This means there's only a single create_window callback now. Also, getFunctions() doesn't have the gl3 parameter anymore, which was confusing and hard to explain. create_window() tries to create a GL context of any version. The field MPGLContext.requested_gl_version is taken as a hint whether a GL3 or a legacy context is preferred. (This should be easy on all platforms.) The cocoa part always assumes that GL 3 is always available on OSX 10.7.0 and higher, and miserably fails if it's not. One could try to put more effort into probing the context, but apparently this situation never happens, so don't bother. (And even if, mpv should be able to fall back to vo_corevideo.) The X11 part doesn't change much, but moving these functions around makes the diff bigger. Note about some corner cases: This doesn't handle CONTEXT_FORWARD_COMPATIBLE_BIT_ARB on OpenGL 3.0 correctly. This was the one thing getFunctions() actually needed the gl3 parameter, and we just make sure we never use forward compatible contexts on 3.0. It should work with any version above (e.g. 3.1, 3.2 and 3.3 should be fine). This is because the GL_ARB_compatibility extension is specified for 3.1 and up only. There doesn't seem to be any way to detect presence of legacy GL on 3.0 with a forward compatible context. As a counter measure, remove the FORWARD_COMPATIBLE flags from the win32 code. Maybe this will go wrong. (Should this happen, the flag has the be added back, and the win32 will have to explicitly check for GL 3.0 and add "GL_ARB_compatibility" to the extra extension string.) Note about GLX: Probing GL versions by trying to create a context on an existing window was (probably) not always possible. Old code used GLX 1.2 to create legacy contexts, and it required code different from GLX 1.3 even before creation of the X window (the problem was selections of the X Visual). That's why there were two functions for window creation (create_window_old and create_window_gl3). However, the legacy context creation code was updated to GLX 1.3 in commit b3b20cc, so having different functions for window creation is not needed anymore.
* gl_common: move things used by vo_opengl_old.c only to vo_opengl_old.cwm42013-01-131-89/+0
| | | | Having this in gl_common is confusing.
* vo_opengl_old: reject 9-15 bit formats if textures have less than 16 bitwm42012-12-281-0/+2
| | | | | | | | | | | | | | | | | | | For 9-15 bit material, cutting off the lower bits leads to significant quality reduction, because these formats leave the most significant bits unused (e.g. 10 bit padded to 16 bit, transferred as 8 bit -> only 2 bits left). 16 bit formats still can be played like this, as cutting the lower bits merely reduces quality in this case. This problem was encountered with the following GPU/driver combination: OpenGL vendor string: Intel Open Source Technology Center OpenGL renderer string: Mesa DRI Intel(R) 915GM x86/MMX/SSE2 OpenGL version string: 1.4 Mesa 9.0.1 It appears 16 bit support is rather common on GPUs, so testing the actual texture depth wasn't needed until now. (There are some other Mesa GPU/driver combinations which support 16 bit only when using RG textures instead of LUMINANCE_ALPHA. This is due to OpenGL driver bugs.)
* Rename directories, move files (step 2 of 2)wm42012-11-121-5/+5
| | | | | | | | | | | | Finish renaming directories and moving files. Adjust all include statements to make the previous commit compile. The two commits are separate, because git is bad at tracking renames and content changes at the same time. Also take this as an opportunity to remove the separation between "common" and "mplayer" sources in the Makefile. ("common" used to be shared between mplayer and mencoder.)
* Rename directories, move files (step 1 of 2) (does not compile)wm42012-11-121-0/+396
Tis drops the silly lib prefixes, and attempts to organize the tree in a more logical way. Make the top-level directory less cluttered as well. Renames the following directories: libaf -> audio/filter libao2 -> audio/out libvo -> video/out libmpdemux -> demux Split libmpcodecs: vf* -> video/filter vd*, dec_video.* -> video/decode mp_image*, img_format*, ... -> video/ ad*, dec_audio.* -> audio/decode libaf/format.* is moved to audio/ - this is similar to how mp_image.* is located in video/. Move most top-level .c/.h files to core. (talloc.c/.h is left on top- level, because it's external.) Park some of the more annoying files in compat/. Some of these are relicts from the time mplayer used ffmpeg internals. sub/ is not split, because it's too much of a mess (subtitle code is mixed with OSD display and rendering). Maybe the organization of core is not ideal: it mixes playback core (like mplayer.c) and utility helpers (like bstr.c/h). Should the need arise, the playback core will be moved somewhere else, while core contains all helper and common code.
