Don't load all the legacy functions (including ancient extensions).
Slightly simplify function loader and context creation, now that legacy
GL doesn't need to be handled. Remove the code for drawing OSD in legacy
mode.
Remove all the header hacks, which were meant for ancient OpenGL headers
which didn't even support things like OpenGL 1.3. Instead, adjust the
GLX check to make sure we get both OpenGL 3x and 2.1 symbols. For win32
and OSX, we assume that the user has the latest headers anyway. For
wayland, we hope that things somehow go right.
While there's no actual need to get rid of these, I want to make sure
nobody actually needs this stuff, and removing it is the best way to
get to know this. We still can revert this commit if it turns out there
is a significant need for this stuff.
The final goal is removing vo_opengl_old entirely. Add a warning, which
basically announces this intention.
Apparently GLX can do this, so using EGL is not strictly required.
This code tries to create an ES context if creating a desktop GL context
fails. Also, a "x11es" backend for forcing ES (instead of desktop GL) is
added, mostly for testing and debugging.
Older OSX versions are missing some OpenGL 3 symbols, apparently. At
least there's some precedent in the headers. Just add the symbols
manually for now to fix OSX (on travis-ci) compilation.
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.
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.)
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.

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.
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.
