The code assumed the last format passed to query_format will be the one
that is used on playback. This is probably true and thus didn't cause any
bugs, but make query_format side effect free just like the other VOs.
Clipping it makes the video output look extremely crappy. There seems no
good reason to do this, and VirtualBox is fine with overlays larger than
the screen.
The code used WM_WINDOWPOSCHANGING to force an spect ratio. This didn't
behave well if the left/top window borders were used for resizing.
Resizing with these borders changed the screen position of the right/bottom
as well, which is unintuitive and annoying.
Use WM_SIZING instead. Unlike WM_WINDOWPOSCHANGING, WM_SIZING knows about
which border is being used for resizing and can act accordingly.
Note that the calculated window size doesn't necessarily match with the
size mplayer calculates, but this problem exists on x11 as well.
This commit fixes various issues with the way the window position and
size is setup. Most importantly, it fixes some bugs with restoring from
fullscreen state.
Rename create_rendering_context() to reinit_window_state(). This function
doesn't create anything, it just sets the window bounds and styles.
Do not use vo_dx/dy for the window position, as video_out.c overwrites it
with each vo_config() call. Use private variables window_x/y instead.
A big cause for issues was that reinit_window_state() accidentally cleared
the WS_VISIBLE style. I suspect that the API call to temporarily hide the
window was a hack to deal with this. Another bug was that the window style
was changed without calling SetWindowPos with SWP_FRAMECHANGED (as the
MSDN documentation says).
Properly initialize window position and size on vo_config following the
same rules as the x11 backend:
- Never change the window position. The window position should be kept, as
the user might move the window, and resetting the window position e.g.
during ordered chapter playback is not desired.
- Never change the window size, unless the size of the video changes.
These rules don't apply to fullscreen. When switching from fullscreen to
windowed mode, the backend should restore the previous windowed size and
position. When the VO was reconfigured during playback (vo_config() etc.),
the saved window position and size should be changed according to the
rules above, even if the window was in fullscreen mode during
reconfiguring.
Note that these rules might be perceived as awkward by some users: if you
play multiple files with different resolutions, the window won't be
centered when playing the files after the first. This is not a bug.
Restore hunk disabling overlay when the Window is minimized.
This was accidentally removed in r33657.
Fixes bug 1950.

Modify the YUV->RGB conversion matrix to take into account the
difference between the same color value being x/255 in a 8-bit texture
and x*256/65535 in a 16-bit texture (actually things are stored as
x*4/65535 for 10-bit color, but that can be ignored here). This 0.4 %
difference in the shader float value could make shades of gray in
10-bit (or generally more than 8 bit) YUV produce RGB values with
green slightly higher than red/blue.
Windows uses a legacy codepage for char* / runtime functions accepting
char *. Using UTF-8 as the codepage with setlocale() is explicitly
forbidden.
Work this around by overriding the MSVCRT functions with wrapper
macros, that assume UTF-8 and use "proper" API calls like _wopen etc.
to deal with unicode filenames. All code that uses standard functions
that take or return filenames must now include osdep/io.h. stat()
can't be overridden, because MinGW-w64 itself defines "stat" as a
macro. Change code to use use mp_stat() instead.
This is not perfectly clean, but still somewhat sane, and much better
than littering the rest of the mplayer code with MinGW specific hacks.
It's also a bit fragile, but that's actually little different from the
previous situation. Also, MinGW is unlikely to ever include a nice way
of dealing with this.
Some of the code, especially the dshow and windows codec loader parts,
are extremely hacky and likely full of bugs. The goal is merely getting
rid of warnings that could obscure more important warnings and actual
bugs, instead of fixing actual problems. This reduces the number of
warnings from over 500 to almost the same as when compiling on Linux.
Note that many problems stem from using the ancient wine-derived
windows headers. There are some differences to the "proper" windows
header. Changing the code to compile with the proper headers would be
too much trouble, and it still has to work on Unix.
Some of the changes might actually break compilation on legacy MinGW,
but we don't support that anymore. Always use MinGW-w64, even when
compiling to 32 bit.
Fixes some warnings in the win32 loader code on Linux too.
Instead of opening avctx in preinit() and setting paramters later,
(re)open it in config() where parameters can be set first. This fixes
a failure to open the codec with new libavcodec versions that check
pix_fmt during avcodec_open2().
vo_xv crashed if existing frames had been lost due to a config() call
in the middle of a file and vo_redraw_frame() was called. Add checks
to reject vo_redraw_frame() unless at least one frame has been flipped
after the the last configuration change, so individual VOs do not have
to deal with this case.
The "backend" suboption allows selecting the GUI backend used by vo_gl.
Normally, it's auto-selected, but sometimes it's desireable to explicitly
select it.
Remove the gl_sdl VO. This can now be done by using: --vo=gl:backend=sdl

Remove the private bswap and intreadwrite.h implementations and use
libavutil headers instead.
Originally these headers weren't publicly installed by libavutil at
all. That already changed in 2010, but the pure C bswap version in
installed headers was very inefficient. That was recently (2011-12)
improved and now using the public bswap version probably shouldn't
cause noticeable performance problems, at least if using a new enough
compiler.
Change various code to use the latest Libav API. The libavcodec
error_recognition setting has been removed and replaced with different
semantics. I removed the "--lavdopts=er=<value>" option accordingly,
as I don't think it's widely enough used to be worth attempting to
emulate the old option semantics using the new API. A new option with
the new semantics can be added later if needed.
Libav dropped APIs that were necessary with all Libav versions
until quite recently (like setting avctx->age), and it would thus not
be possible to keep compatibility with previous Libav versions without
adding workarounds. The new APIs also had some bugs/limitations in the
recent Libav release 0.8, and it would not work fully (at least some
avcodec options would not be set correctly). Because of those issues,
this commit makes no attempt to maintain compatibility with anything
but the latest Libav git head. Hopefully the required fixes and
improvements will be included in a following Libav point release.
Setting the WM_NAME/WM_ICON_NAME window properties didn't always work:
apparently there are some characters that can't be represented in the X
STRING or COMPOUND_TEXT encodings, such as U+2013 EN DASH. The function
Xutf8TextListToTextProperty partially converts the string, and returns
a value different from 'Success'. This means vo_x11_set_property_string
didn't set these window properties.
On most modern window managers, this is not a problem, since these use
the _NET_WM_NAME/_NET_ICON_NAME and the UTF8_STRING encoding. Some older
WMs like IceWM don't read these, and the window title remains blank.
It's not clear what exactly we should do in this situation, but fix it
by setting set the WM_NAME/WM_ICON_NAME properties as UTF8_TEXT. This
violates the ICCCM, but at least IceWM seems to handle this well.

Also fix a minor memory leak when conversion to COMPOUND_TEXT fails.
At least on some keyboards, the key between '0' and 'Enter' on the
key pad is mapped to KP_Separator. Since X11 VOs accept unicode
input, the mplayer keycode this key generates depended on the numlock
state, and with numlock enabled this mapped to an ASCII character.
This is probably not what the user wanted, since two physical keys
will always map to the same key code.
Map it to KP_DEC.
This change allows using non-ASCII keys with X11. These keys were ingored
before.
Technically, this creates an invisible, non-interactive input method
context. If creation fails, the code falls back to the old method, which
allows a subset of ASCII only.
This is an experiment.
The change probably doesn't matter much.
One issue with the old code was that "large" images caused each sub-image
to be created and rendered as a new texture. "Large" in this case means
larger than 32x32 pixels, which actually isn't very large with screen
sizes beyond 1500x1000 pixels. This means rendering a simple subtitle for
a fullscreened video may allocate many small textures, one for each glyph.
On the other hand, the old code could be fixed by tuning the texture sizes
for "modern" work loads.
Also, the new code uses less deprecated OpenGL features and draws all
sub-images in one batch.
There are two possible issues the new code could cause:
- Drivers could have performance issues with the larger texture sizes and
the number of glTexSubImage2D calls on it
- There is only one EOSD texture, which could become full (it's enlarged
on demand, but restricted by driver texture size limitations)
It has been reported that this is faster on OSX with ATI GPUs than the old
code.
The code in eosd_packer.c/.h is taken from vo_vdpau.c and has been made
independent from vdpau API specifics. This allows other VOs, which need
to pack the small EOSD images into a large surface for efficiency, to use
this code.
Recent commits for screenshot support and video redraw changes didn't
handle vdpau driver preemption state correctly, which could make the
player crash if preemption occurred. Fix this and improve preemption
handling a bit otherwise.
Currently there is no way to set the swap interval with a function
that has a signature compatible with other platforms' gl extensions.
Make a wrapper function around the gui toolkit method of setting the
swap interval property, and point gl->SwapInterval to it.
Remove the useless dependency on MPGLContext from cocoa_common, since
it was used just to access the vo struct. Change gl_common to pass the
vo struct directly to all the cocoa_common functions.
Always set the X11 window title properties as UTF-8. This is a bit tricky
for X11 window properties which are not specified to use UTF-8, such as
WM_NAME.
We also properly set WM_ICON_NAME, which means the window caption and the
text used in the task bar (of the WM has one) will be the same on most
window managers. Before this commit, WM_ICON_NAME was always hardcoded to
"MPlayer", even if --title or --use-filename-title was used.
Also update the window title only on reconfigure, like it is done in
mplayer-svn commit 34380.
This affects only the "new" VO API. The config() title argument was barely
used, and it's hardcoded to "MPlayer" in vf_vo.c. The X11 and the Cocoa
GUI backends, which are the only ones properly supporting window titles,
ignored this argument. Remove the title argument.
Add the vo_get_window_title function. All GUI VOs are supposed to use it
for the window title.
Remove code refreshing window contents after events such as resize
from vo_vdpau, vo_gl and vo_xv. Instead have them simply set a flag
indicating that a refresh is needed, and have the player core perform
that refresh by doing an OSD redraw. Also add support for updating the
OSD contents over existing frames during slow-but-not-paused playback.
The VOs now also request a refresh if parameters affecting the picture
change (equalizer settings, colormatrix, VDPAU deinterlacing setting).
Even previously the picture was typically redrawn with the new
settings while paused because new OSD messages associated with setting
changes triggered a redraw, but this did not happen if OSD was turned
off.
A minor imperfection is that now window system events can trigger a
single one-frame step forward when using vo_xv after pausing so that
vo_xv does not yet have a copy of the current image. This could be
fixed but I think it's not important enough to bother.
Previously the core sent VFCTRL_REDRAW_OSD to change OSD contents over
the current frame. Change this to VFCTRL_REDRAW_FRAME followed by
normal EOSD and OSD drawing calls, then vo_flip_page(). The new
version supports changing EOSD contents for libass-rendered subtitles
and simplifies the redraw support code needed per VO. vo_xv doesn't
support EOSD changes because it relies on vf_ass to render EOSD
contents earlier in the filter chain.
vo_xv logic is additionally simplified because the previous commit
removed the need to track the status of current and next images
separately (now each frame is guaranteed to become "visible" soon
after we receive it as "next", with no VO code running in the interval
between).
Separate passing a new frame to VOs using the new API into two steps.
The first, vo_draw_image(), happens after a new frame is available
from the filter chain. In constrast to old behavior, now the frame is
not actually rendered yet at this point (though possible slice draw
calls can already reach the VO before). The second step,
vo_new_frame_imminent(), happens when we're close enough to the
display time of the new frame that we'll commit to flipping it as the
next action and will not change the OSD over the previous frame any
more.
This new behavior fixes a previous problem with vo_vdpau and vo_gl in
the situation where the player is paused after decoding a new frame
but before flipping it; previously changing OSD in that state would
switch to the new frame as a side effect. It would also allow an easy
way to fix extra output files produced with something like "--vo=png
--frames=1" with precise seeking, but this is not done yet.
The code now relies on a new mp_image from the filter chain staying
valid even after the vf_vo put_image() call providing it returns. In
other words decoders/filters must not deallocate or otherwise
invalidate their output frame between passing it forward and returning
from the decode/filter call.
Add native Cocoa code to display an OpenGL window. Some of the code is
based on the OpenGL parts of vo_corevideo but I took the time to remove
old code based on Carbon.
There is autodetection in the configure script but you can use
--enable[disable]-cocoa to enable[disable] this.
When interpreting a key event, use the "charactersIgnoringModifiers"
method of the event in order to extract Alt+key combinations while
keeping the normal meaning of "key". When the right alt modifier is
pressed use the "characters" method to allow AltGr behavior to be used
to generate different characters.
The ARB shader code generated at the end of the shaders for scaling mode 4
and 5 was something like:
MAD yuv.g, b.r, {0.5}, a.r;
This appears to be semantically equivalent with:
MAD yuv.g, b.rrrr, {0.5, 0, 0, 0}, a.rrrr;
This has the consequence that the result register, yuv.g, will not contain
the value computed by the scale filter, but a.r. a.r is the unchanged
value sampled from the normal texture coordinates, so the filter did
effectively nothing and behaved as if cscale=0 was specified. The basic
mistake here is that yuv.g does not specify a single register, but it
specifies the full vector register yuv, with writing enabled on the g
channel. This means yuv.g will assigned the g channel of the the result
vector computed by the MAD instruction.
The GL_LUMINANCE16 texture format had only 8 bit precision on Mesa
based drivers. This caused heavy degradation of the image when playing
formats with more than 8 bits per pixel, such as 10 bit h264. Use
GL_R16 instead, which at least Mesa and Nvidia drivers actually
implement as 16 bit textures. Since sampling from this texture format
doesn't return anything meaningful in the other color components
(unlike luminance textures), the shader code has to be slightly
changed.
GL_R16 requires the GL_ARB_texture_rg extension. Check for it, and fall
back to the old texture format if it's not available.
The low precision of the GL_LUMINANCE16 format has just been fixed in
upstream Mesa, but it'll take a while before that fix is available in
distros.
The shader code was generated from very long strings with lots of
format specifiers with snprintf calls. It was almost impossible to
quickly tell what variables were inserted where in the shader. Make
this more readable by implementing a kind of simple variable
substitution, which allows replacing the format specifiers in the code
templates with with variable names.
