Until now, there were two functions to add input sources (stuff like
stdin input, slave mode, lirc, joystick). Unify them to a single
function (mp_input_add_fd()), and make sure the associated callbacks
always have a context parameter.
Change the lirc and joystick code such that they take store their state
in a context struct (probably worthless), and use the new mp_msg
replacements (the point of this refactoring).
Additionally, get rid of the ugly USE_FD0_CMD_SELECT etc. ifdeffery in
the terminal handling code.
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.
Move the definitions of all special key codes (those not passed by
ASCII value) to input/keycodes.h. Before they were spread between
osdep/keycodes.h, input/joystick.h, input/mouse.h and input/ar.h, plus
some special values in input.h. This was especially inconvenient as
the codes had to be coordinated to not conflict between the files.
The change requires a bit of ugliness as appleir.c includes
<linux/input.h> which contains various conflicting KEY_* definitions.
Work around this by adding a special preprocessor variable which can
be used to avoid defining these in keycodes.h.
Use the same mp_input_add_key_fd for all uses and add a context
argument to its callback that was before only in the event fd
callbacks. Instead of checking in input.c whether keys were inserted
to the keypress FIFO during the callback do the check in the callback
before returning and set return value accordingly.
