Move them into per-instance structs. This should get rid of all global
variables in mplayer.c (not counting those referenced by cfg-mplayer.h).
In core/input/ar.c, just remove checking the slave_mode variable. I'm
not sure what this code was supposed to achieve, but slave mode is
broken, slave mode is actually infeasible on OSX (ar.c is completely OSX
specific), and the correct way of doing this would be to disable this
input device per command line switch.
Missing entries cause avcodec_descriptor_get() to return NULL, and in
turn mp_codec_from_av_codec_id() will return NULL. This shouldn't
happen, and avcodec_descriptor_get() returning NULL for a valid codec is
clearly a bug.
But make it more robust anyway, and use the decoder's name if this
happens, because I doubt maintainance of the AVCodecDescriptor table
in ffmpeg/Libav will always be perfect and reliable.
Latest nvidia drivers ignore the application setting, so this switch
makes even less sense than before. It's still possible to control this
with VO specific suboptions.
Separate the video output options from the big MPOpts structure and also only
pass the new mp_vo_opts structure to the vo backend.
Move video_driver_list into mp_vo_opts
The spdif decoder was hardcoded to assume that the spdif output is
capable of accepting high (>1.5Mbps) bitrates. While this is true
for modern HDMI spdif interfaces, the original coax/toslink system
cannot deal with this and will fail to work.
This patch adds an option --dtshd which can be enabled if you use
a DTS-capable receiver behind a HDMI link.
Removes almost every global variabel in vo.h and puts them in a special struct
in MPOpts for video output related options.
Also we completly remove the options/globals pts and refresh rate because
they were unused.
Commit 9efe32120 stops recreating the hidden window used for OpenGL's
extensions autodetection. The `cocoa_common` code assumed the hidden flag could
only come when creating a window which is now not true anymore.
Move some code around so that hidden, fullscreen and window position are
respected on subsequent calls of config.
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to make compilation possible on systems with outdated GL headers.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.
When paused, --cursor-autohide worked with a precision of 500ms, which
is the main loop's default sleep time when paused. Cursor hiding is
polled in x11_common, and the main loop never called the X11 code at
the right time. Fix this by allowing the VO to set a time when it
should be called next.
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.
vo_opengl creates an invisible window with VOFLAG_HIDDEN in order to
test whether the OpenGL context is useable. The visible window is
created at a later point. This has been broken forever (in vo_gl,
now called vo_opengl_old, it could be avoided by disabling auto-
detection explicitly using the "yuv" sub-option). Avoiding
VOFLAG_HIDDEN only mitigates the issue, and a related bug can still
happen with some window managers (see below).
As a hack, code was added to vo_gl to destroy the (hidden) window so
that all state was destroyed. Later, more hacks were added to deal with
some caveats that came with recreating the window, such as probing for
the context up to 4 times.
Attempt to fix the problem properly. There were two problems: first,
the window was not resized to video size before mapping. This was the
main cause for the placement issue, e.g. mapping the window as 320x200,
and then resizing it. Second, mpv tried to force the window position
with XSetWMNormalHints and PPosition with values it just read with
XGetGeometry. This messes up the window manager's default placement.
It seems to be a race condition, and behavior is different across
various WMs too: with IceWM, the window manager's placement is usually
preferred, and with Fluxbox, mpv's position is preferred. mpv's default
position is centering the window on the screen, which is much nicer for
video in general than typical WM default placement, so it's possible
that this bug was perceived as a feature. (Users who want this have to
use --geometry="50%:50%", doing this by default is probably not safe
with all WMs.)
Since the old code was hard to follow and full of issues, it's easier
to redo it. Move general window creation stuff out of the
vo_x11_config_vo_window function, and move the resize logic into it.
This has been tested on IcwWM, Fluxbox, awesome, Unity/Compiz.
Store the window state (position and size) in vo_x11_state, instead of
in vo->dx/dy/dwidth/dheight. The VO variables are overwritten by vo.c on
every vo_config() call, which is extremely not helpful.
Now vo->dx/dy are mostly unused (except for passing the position forced
by the --geometry option), and vo->dwidth/dheight are set for the VO,
and otherwise read for resize detection only.
In the long term, the way vo_config() handles the --geometry option
should be changed, and vo->dx/dy should be removed.
Remove some useless stuff: VO_EVENT_MOVE and VO_EVENT_KEYPRESS were
generated, but unused. Wayland changes by Alexander Preisinger.
It was once used for vo_sdl (the old one based on SDL 1.2), since SDL
apparently lost the GL state when switching to fullscreen. The new
vo_sdl (using SDL 1.3) doesn't use or need this. It's dead code, so
get rid of it.
I doubt anyone needs to adjust hue on a frequent basis, and gamma is
much more useful.
Suggestions for more radical changes of key bindings are welcome
(there's a lot of useless crap mapped).
Emulate percentage-seeks (SEEK_FACTOR) as normal time-seeks if possible.
This fixes some issues with (let's call it) low quality implementations
of SEEK_FACTOR (e.g. demux_mkv basically interprets this as byte-seek,
and also seeking to 99.9% makes it seek back to the start).
For weird MPEG formats the demuxer level SEEK_FACTOR is still used.
These formats, which can have timestamp resets, are identified by
setting demuxer->ts_resets_possible to true.
Also, have get_current_pos_ratio() follow the same rules, and calculate
the percentage position with the file position if timestamp resets are
possible.
This actually fixes percentage-seeks in .ts files with demux_lavf.c.
This kind of seek is not really used now, but it will be more important
when we add a progress bar.
Note: seeking in chained ogg files is still completely broken. The main
issue is that ffmpeg doesn't provide a sane API for dealing with
timestamp resets, and trying to do byte seeks with ogg confuses demuxer
and decoder (or something like this) and just does random things.
(Tested with two concatenated flac-in-ogg files).
AVFormatContext.start_time is sometimes AV_NOPTS_VALUE, such as when
playing FLAC files. (For most other file formats it's set to 0, even if
the format doesn't support arbitrary start times.)
OPT_BASE_STRUCT defines which struct the OPT_ macros (like OPT_INT etc.)
reference implicitly, since these macros take struct member names but no
struct type. Normally, only cfg-mplayer.h should need this, and other
places shouldn't be bothered with having to #undef it.
(Some files, like demux_lavf.c, still store their options in MPOpts. In
the long term, this should be removed, and handled like e.g. with VO
suboptions instead.)
Change the option definition macros so that they cause compiler warnings
if the type of the referenced option struct member doesn't match the
type implied by the macro. The compiler warning printed isn't very
telling, but it's better than silently invoking undefined behavior by
violating the C strict aliasing rules.
Also fix some minor cases that violate the type rules. For the option
"no-aspect" we have to add a new option type to handle it properly.
Some option types are hard to check, so we don't in these cases.
VFCAP_OSD was used to determine at runtime whether the VO supports OSD
rendering. This was mostly unused. vo_direct3d had an option to disable
OSD (was supposed to allow to force auto-insertion of vf_ass, but we
removed that anyway). vo_opengl_old could disable OSD rendering when a
very old OpenGL version was detected, and had an option to explicitly
disable it as well.
Remove VFCAP_OSD from everything (and some associated logic). Now the
vo_driver.draw_osd callback can be set to NULL to indicate missing OSD
support (important so that vo_null etc. don't single-step on OSD
redraw), and if OSD support depends on runtime support, the VO's
draw_osd should just do nothing if OSD is not available.
Also, do not access vo->want_redraw directly. Change the want_redraw
reset logic for this purpose, too. (Probably unneeded, vo_flip_page
resets it already.)
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.

Use floats instead of integers in the range 0-100. Currently, the OSD
is currently made up of 46 elements so no change should be visible, but
rendering of the bar will be changed later to use vector drawings (using
pixel coordinates) instead of glyphs. This commit is for preparation.
The percent position is used for the OSD, the status line, and for the
OSD bar (shown on seeks). By default, the PTS of the last demuxed packet
was used to calculate it. This led to a "jumpy" display when the
percentage value (casted to int) was changing. The reasons for this were
the presence of video frame reordering (packet PTS is not monotonic), or
getting PTS values from different streams (like audio/subs).
Since these rely on PTS values and correct file durations anyway,
simplify it by calculating it with the current playback position in
mplayer.c instead.
This allowed making the player switch the monitor video mode when
creating the video window. This was a questionable feature, and with
today's LCD screens certainly not useful anymore. Switching to a random
video mode (going by video width/height) doesn't sound too useful
either.
I'm not sure about the win32 implementation, but the X part had several
bugs. Even in mplayer-svn (where x11_common.c hasn't been receiving any
larger changes for a long time), this code is buggy and doesn't do the
right thing anyway. (And what the hell _did_ it do when using multiple
physical monitors?)
If you really want this, write a shell script that calls xrandr before
and after calling mpv.
vo_sdl still can do mode switching, because SDL has native support for
it, and using it is trivial. Add a new sub-option for this.
The --wid switch (for embedding the player into other applications)
didn't create a new window, and instead tried to use the window that
was passed via --wid directly. This made the code more complex, caused
strange X errors (mpv and host application fighting for exclusive X
resources), and actually could cause issues if the --wid window wasn't
created with the X Visual needed for OpenGL.
Always create a window instead. This makes it always possible to embed
the player into foreign windows. --geometry doesn't work anymore - the
controlling application should always create a new window to place the
player inside it, and can control the video window by moving and
resizing this window.
w32_common.c actually did this right, and always creates a new window.
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.
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.
The message reads: "Screenshot: filename", where the filename is what
mpv passes to fopen(). It will also show error messages when saving the
screenshot fails.
