Doing "mpv --vo=opengl:lscale=help" now lists possible scalers and
exits. The "backend" suboption behaves similar. Make the "stereo"
suboption a choice, instead of using magic integer values.
Commit 6ab2eeb attempted to fix it on Cygwin, but now it broke on MinGW
in turn. Don't think too hard about it and just remove the code. (vo.c
already prints the video rectangle anyway.)
Nothing should change from user perspective.
mpv --vo=opengl:help now works.
Remove the vo_opengl inline help text. The new code can list option
names for you, but that's it. Refer to the manpage if you have trouble.
For some reason, both m_config and m_struct are somewhat similar, except
that m_config is much more powerful. m_config is used for VOs and some
other things, so to unify them. We plan to kick out m_struct and use
m_config for everything. (Unfortunately, m_config is also a bit more
bloated, so this commit isn't all that great, but it will allow to
reduce the option parser mess somewhat.)
This commit also switches all video filters to use the option macros.
One reason is that m_struct and m_config, even though they both use
m_option, store the offsets of the option fields differently (sigh...),
meaning the options defined for either are incompatible. It's easier to
switch everything in one go.
This commit will allow using the -vf option parser for other things,
like VOs and AOs.
When the cursor was in the window border, it could be hidden but it
wouldn't appear again, since mpv doesn't process mouse input there.
The code used ShowCursor, which is a horrid stateful API designed for
mouseless Win16 systems that incremented or decremented a global counter
to keep track of how many applications needed to display a special
cursor (like a busy cursor.) Replace that with a simple flag, handle
WM_SETCURSOR and use SetCursor(NULL) to hide the mouse cursor, but only
when the mouse is in the client area. DefWindowProc will set the correct
cursor on the border as long as it isn't hidden with ShowCursor.
PowerPoint also uses SetCursor(NULL) to hide the cursor when showing a
presentation, so it's probably safe.
See http://blogs.msdn.com/b/oldnewthing/archive/2009/12/17/9937972.aspx
This change which also flipse the coordinate system of the view, greatly
simplifies the mouse event handling code.
There are still some uglities mostly related to the cursor visibility
code. For instance the core doesn't show the cursor when it receives a mouse
leave event.
This was more roundabout than expected, since it looks like the framework
caches isMovabileByWindowBackground so in mpv's case it's needed to set it
with setMovableByWindowBackground.
This commit removes the pointer to the single different structures for input
and window and puts them as anonymous structures inside the wayland_state
structure.
This has the disadvantage of passing the substructure to the listeners, but the
advantage is that we don't have to allocate them and check for NULL pointers.
This makes it more reliable and easier to follow.
The vo_wayland_fullscreen handles resizing for the video, because the video
could still be in fullscreen mode and resizing it in gl_wayland could make it
grow or shrink.
There was a MPOpts fullscreen field, a mp_vo_opts.fs field, and
VOFLAG_FULLSCREEN. Remove all these and introduce a
mp_vo_opts.fullscreen flag instead.
When VOs receive VOCTRL_FULLSCREEN, they are supposed to set the
current fullscreen mode to the state in mp_vo_opts.fullscreen. They
also should do this implicitly on config().
VOs which are capable of doing so can update the mp_vo_opts.fullscreen
if the actual fullscreen mode changes (e.g. if the user uses the
window manager controls). If fullscreen mode switching fails, they
can also set mp_vo_opts.fullscreen to the actual state.
Note that the X11 backend does almost none of this, and it has a
private fs flag to store the fullscreen flag, instead of getting it
from the WM. (Possibly because it has to deal with broken WMs.)
The fullscreen option has to be checked on config() to deal with
the -fs option, especially with something like:
mpv --fs file1.mkv --{ --no-fs file2.mkv --}
(It should start in fullscreen mode, but go to windowed mode when
playing file2.mkv.)

This was bad, because it was the only aspdat member updated by
vo_get_src_dst_rects() instead of vo_reconfig(). Now it isn't
accessed anymore, so remove it.
Until now, only formats directly supported by OpenGL were supported.
This excludes various permutations of 8-bit RGB[A|0]. But we can simply
permutate the color channels in the shader, so do that. This also adds
support for all these weird RGB0 formats.
Note that we could use libavutil's pixfmt list instead of the
mp_packed_formats array, but trying to decrypt the pixfmt info would
probably end in pain, so this array with duplicated information is
actually better and shorter.
Note: I didn't actually test whether the alpha components are reproduced
correctly with alpha formats.
Image parameters like colorspace, color levels, and chroma location are
generally less important, and many filters don't set them correctly.
Force them instead in the generic VF code, which is probably better and
more convenient over all. So we designate this is a proper solution,
instead of a dirty hack.
This splits the monolithic mp_image_swscale() function into a bunch of
functions and a context struct. This means it's possible to set
arbitrary parameters (e.g. even obscure ones without getting in the
way), and you don't have to create the context on every call.
This code is preparation for removing duplicated libswscale API usage
from other parts of the code.
libswscale doesn't seem to require this (anymore?), and libavfiltert's
vf_scale doesn't do it either. Moreover, this wasn't done for most other
subsampled formats, not even very old ones. So just remove it.
(It'd be quite easy to align on chroma boundaries with all pixel
formats, though.)
Until now, vf_scale only tried formats listed in the outfmt_list array.
Extend this and try every pixel format supported by mpv if trying
outfmt_list doesn't lead to success.
Also add some checks whether swscale really supports a given input or
output format. This was implicitly done with outfmt_list before.
ffmpeg's and the internal palette format used to have different
endianess, but that is not the case anymore. This code was forgotten
when that change was made.
I guess this code was supposed to handle cases like drawing RGBA as ARGB
by offsetting it by 1 byte.
The code didn't make any sense, though. It used to make sense before mpv
switched internal pixel formats from FourCCs to a simple enum. With the
FourCCs, "fmt | 128" selected the big endian version of a format. Of
course this doesn't work this way with the new pixel formats. It just so
happens that there are no formats with whose values match
IMGFMT_RGB32|128 or IMGFMT_BGR32|128, so this code was inactive.
All involved pixel formats seem to play fine on my setup (though it's
little endian only), and the code strictly matches the mpv pixel formats
against the format of the X image, so I'm not quite sure why this code
was there in the first place.
The original commit that added this was b333ae1 (svn 21602):
Support for different endianness on client and server with -vo x11
Instead of handling colorspaces with VFCTRLs/VOCTRLs, make them part of
the normal video format negotiation. The colorspace is passed down like
other video params with config/reconfig calls.
Forcing colorspaces (via the --colormatrix options and properties) is
handled differently too: if it's changed, completely reinit the video
chain. This is slower and requires a precise seek to the same position
to perform an update, but it's simpler and less bug-prone. Considering
switching the colorspace at runtime by user-interaction is a rather
obscure feature, this is a good change.
The colorspace VFCTRLs and VOCTRLs are still kept. The VOs rely on it,
and would have to be changed to get rid of them. We'll do that later,
and convert them incrementally instead of in one go.
Note that controlling the output range now always works on VO level.
Basically, this means you can't get vf_scale to output full-range YUV
for whatever reason. If that is really wanted, it should be a vf_scale
option. the previous behavior didn't make too much sense anyway.
This commit fixes a few bugs (such as playing RGB video and converting
that to YUV with vf_scale - a recent commit broke this and forced the
VO to display YUV as RGB if possible), and might introduce some new
ones.
Calculate the aspect ratio in vo_config, when we get the window size and in the
inside the resize function we calculate the aspect ratio of the output in order
to determine if we have to change the height or the width of the video.
If the ratio of the output is bigger than the ratio of the video then we have
to set the width accordingly and if the ratio is smaller we change the size.
But only if no resize edges are passed, because this indicates that we want to
change the windows state instead of just a simple resize and the video should
not grow bigger than the requested size.
aspdat.asp is a problem, because it's updated when the VO calls
vo_get_src_dst_rects(). Nothing guarantees that the value has been
updated when the w32 code accesses it.
Instead, use the aspect vo_w32_config() was called with.
