Move sub-bitmap definitions from dec_sub.h to sub.h. While it's a bit
odd that OSD data structures are in a file named sub.h, it's definitely
way too strange to have them in a file about subtitle decoding. (Maybe
sub.h/.c and the sub/ directory should be split out and renamed "osd"
at a later point.)
Remove including ass_mp.h (and the libass headers) where possible.
Remove typedefs for mp_eosd_res and sub_bitmaps structs.
Store a mp_eosd_res struct in osd_state instead of just w/h. Note that
sbtitles might be rendered using different sizes/margins when filters
are involved (the subtitle renderer is not supposed to use the OSD res
directly, and the "dim" member removed in the previous commit is
something different).
Passing parameters from caller to subtitle renderer was done by
temporarily setting certain members in the osd_state struct (which for
all practical purposes are as good as global variables). This was the
only purpose of these members.
Rather than using such a messy way to pass parameter, put these into a
struct sub_render_params. The struct was already introduced in earlier
commits, and this commit just removes the parameter passing hack.
Before this commit, vf_vo.c and vf_ass.c were manually calling the
subtitle decoder to retrieve images to render. In particular, this
circumvented the sub-bitmap conversion & caching layer in sub.c.
Change this so that subtitle decoding isn't special anymore, and draws
all subtitles with the normal OSD drawing API.
This is also a step towards removing the need for vf_ass auto-insertion.
In fact, if auto-insertion would be disabled now, VOs with "old" OSD
rendering could still render ASS subtitles in monochrome, because
there is still ASS -> old-OSD bitmap conversion in the sub.c mechanism.
The code is written with the assumption that the subtitle rendering
filter (vf_ass) can render all subtitle formats. Since vf_ass knows the
ASS format only, rendering image subs (i.e. RGBA subs) with it simply
fails. This means that with vo_xv (vf_ass auto-inserted), image subs
wouldn't be rendered. Use a dumb hack to disable rendering subs with a
filter, if we detect that the subs are not in ASS format. (Trying to
render the subs first would probably result in purging the conversion
cache on every frame.)
VOs which could render the OSD in window size (as opposed to video size,
like vo_xv) and which could cache the OSD called this when the window
size changed. This was needed, because VOs used another OSD function to
check whether the OSD changed before passing the new window size to the
OSD code.
This was really just an artifact of OSD change detection, and now that
the affected VOs use the new OSD rendering API, it's done automatically.
This contains about the same code as bitmap_packer.c. eosd_packer.c was
added first, and then not merged for a year - then it was added as
bitmap_packer.c with slightly different and incompatible interface. Now
replacing eosd_packer.c with bitmap_packer.c is finally done. So much
wasted work...
Side effect: no direct support for old OSD format anymore. Instead,
sub.c converts sub-images in that format to the packed, alpha-inverted
version.
osd-color suboption is broken.
This was an extremely obscure setting, as it was used only with vo_gl
if its scaled-osd suboption was used. If you really want this, you can
set the desired ass-hinting value directly, and there will be literally
no loss in functionality.
Note that this didn't actually test whether the EOSD was scaled.
Basically, it only checked whether vo_gl had the scaled-osd suboption
set.
Useless. It complicated the code and caused flicker, and was useless
otherwise. The manpage describes this option as "should not normally
be used".
One possibly useful effect from the point of view of the user was that
vsync was disabled. You can do this with the --vsync option, or by
changing X/driver settings directly.
With this commit, the player will still use spudec.c (the "old" DVD sub
decoder), rather than ffmpeg. But it brings the changes needed to enable
this down to a single line change:

sub_init(mpctx->sh_sub, mpctx->osd);
Also, copy the DVD resolution heuristics from spudec.c (from the
spudec_new_scaled() function). I'm not sure if this is correct or even
needed, but the sd_lavc codd explicitly reverted back to spudec with
code carrying this comment:
// Assume resolution heuristics only work for PGS and DVB
so it seems likely that the required heuristics were missing, and that
the spudec heuristics may make the DVD compatibility situation at least
as good as with spudec.
Note that it's unlikely that we enable sd_lavc for DVD subs by default,
as there are other problems in combination with direct DVD playback.
We are using libass for OSD rendering. One problem with that is that
libass has to be bug-compatible to VSFilter. This includes the setting
for the default RTL base direction. Neutral would be most reasonable,
but VSFilter assumes LTR.
This commit forces the default to neutral.
Unconfirmed whether this actually works as intended.
See the following libass commits:
9dbd12d shaper: allow font encoding -1 for neutral base direction
a80c45c shaper: always use LTR base direction by default
libass may always return a full change if no subtitle images are
rendered in some cases (empty tracks). Also, a full change despite empty
sub-images list may be reported on initialization. Avoid invoking odd
special cases in the VO code by always exiting early if the sub-image
list is empty.
Note that at least for OSD, the code in sub.c doesn't even send a
request VOCTRL_DRAW_EOSD if the image list is empty. But the subtitle
rendering code in vf_vo.c is independent from this (at least for now).
This allows vo_vdpau to render OSD directly, without the indirection
through the old OSD API, and without the additional conversions.
Remove support for the old OSD format. Only the mplayer DVD subtitle
decoder still generates this format. Although the new OSD interface does
support this format, remove it from vo_vdpau. It would be relatively
hard to support it in the EOSD code, as it requires two surfaces. (These
two surfaces are blended on top of each other to emulate the mplayer OSD
format.) The correct way to implement direct support for DVD subs would
consist of adding a paletted image format of some sort. But even sd_lavc
converts paletted subtitle images to RGBA, so doing something special
just for DVD subs is not worth it.
This means the frontend (sub.c) converts the subtitles to RGBA if it
detects that vo_vdpau does not support them natively.
The mplayer DVD sub decoder is the only remaining OSD image producer
that still requires the old mplayer OSD format (SUBBITMAP_OLD_PLANAR).
To make supporting this format optional in VOs, add a step that allows
converting these images to RGBA in case the VO doesn't have direct
support for it.
Note: the mplayer DVD sub decoder uses the old mplayer OSD format
(SUBBITMAP_OLD_PLANAR), which is assumed to use premultiplied alpha.
However, it seems DVDs allow only binary transparency, so the rendered
result will be the same.
Before this commit, the OSD was drawn using libass, but the resulting
bitmaps were converted to the internal mplayer OSD format. We want to
get rid of the old OSD format, because it's monochrome, and can't even
be rendered directly using modern video output methods (like with
OpenGL/Direct3D/VDPAU).
Change it so that VOs can get the ASS images directly, without
additional conversions. (This also has the consequence that the OSD can
render colors now.) Currently, this is vo_gl3 only. The other VOs still
use the old method. Also, the old OSD format is still used for all VOs
with DVD subtitles (spudec).
Rewrite sub.c. Remove all the awkward flags and bounding boxes and
change detection things. It turns out that much of that isn't needed.
Move code related to converting subtitle images to img_convert.c. (It
has to be noted that all of these conversions were already done before
in some places, and that the new code actually makes less use of them.)
This basically pushes the old OSD bitmaps via VOCTRL_DRAW_EOSD to the
VO, instead of using the old callback-based interface.
Future commits will change the code such that sub.c pushes images
rendered by libass directly, rather than converting them to the old
OSD format first.
One sub_bitmaps struct could contain either a libass ASS_Image list, or
a mplayer native list of sub-bitmaps. This caused code duplication in
vo_vdpau.c and bitmap_packer.c.
Avoid this by creating such a sub_bitmap array even with libass. This
basically copies the list and recreates it in mplayer's native format.
It gets rid of the code duplication, and will make implementing extended
subtitle and OSD rendering in other VOs easier.
Also do some cosmetic changes and other preparations for the following
commits.
Otherwise it heavily violates the manpage's description, and describing
what it did before in the documentation is something too complicated to
describe in the English language.
rawvideo is a rather primitive demuxer that doesn't implement track
switching. The problem was that during track switching the demuxer
implementations normally set the stream IDs in order to do the switch,
and since rawvideo obviously didn't do that, so the current stream in
ds->sh / demuxer->video->sh was set to NULL. (The frontend always
assumes track switching is successful, which is a reasonable
assumption - failing due to missing video codecs etc. is in separate
codepaths.) Later, demux_rawvideo_fill_buffer() in demux_rawvideo.c
tried to dereference the NULL stream and crashed.
Other trivial single-stream demuxers worked fine, because they didn't
try to access ds->sh.
When setting an alias option, its value is not saved in the file-local
options case. The ensure_backup function in m_config.c exits if it
encounters an aliased option, because it should not be saved
additionally to the original option. However, the original option is
likely never saved in this case.
Change it so that ensure_backup always accesses the original option.
The original option is the one that first appears in the option list.
The m_option_value union is supposed to contain a field for each
possible option type (as long as it actually stores data). This helps
avoiding silly temporary memory alocations. Using a pointer to an union
and to a field of the union interchangeably should be allowed by
standard C.
This removes the alternative values like "off", "0", "false" etc., and
also the non-English versions of these.
This is done for general consistency. It's better to have a single way
of doing things when multiple ways don't add singificant value.
Also update some choices for consistency.
The old maximum is 100%. Raise it to PA_VOLUME_UI_MAX, which is about
150%. PA_VOLUME_UI_MAX is the PulseAudio recommended UI-settable
maximum volume, so it seems to be a good idea to use that.
--softvol is enabled by default. For most audio outputs, this is a good
thing, as they have either their own (bad) soft volume implementation,
or control the system mixer. With ao_pulse, the situation is a bit
different: it supports per-application volume (i.e. volume control is
not really global). More importantly, ao_pulse uses a rather large audio
buffer, and changing the volume with mplayer's volume filter has a large
delay. With the native ao_pulse volume control, it's instant, because
PulseAudio's audio filtering happens at a later stage in its processing
pipeline (inaccessible for mplayer).
This means native volume control should really be allowed for ao_pulse,
while it's the reverse for other audio outputs. Make --softvol a choice
option, and add a new "auto" choice. This is default and will use PA's
volume control with ao_pulse, and mplayer's volume filter otherwise
(i.e. the old softvol behavior).
OpenAL is disabled by default, because it supposedly inteferes with
some other configure tests and makes them fail silently.
Previously, --enable-openal followed configure's utterly braindead
semantics and disabled auto detection. However, since OpenAL was
disabled by default, there was no easy way to enable OpenAL at all,
even if it was explicitly requested. Solve this by making
--enable-openal use auto detection.
When playing a network stream, the cache is automatically enabled. We
don't want the cache to stay enabled when playback ends. (For example,
the next file to be played could be a local file, and even if that is
relatively contrieved, we want to do the right thing.)
Introduced the flag M_OPT_LOCAL to force an option to be always file
local. This allows enabling the old mplayer semantics on a per option
basis.
Now it actually aborts, even if the abort command is not the first
command.
Make a policy change: commands before the abort command are silently
thrown away. Previously, normal commands were run after the abort
command finished (so they were run out of order). I'm not sure which
way is the best, all things considered, but the new way is simpler.
fixes issue with | less, where mplayer broke less's terminal
expectations and made less quit
Note this means that read() will be blocking again. Should be ok, as we
always check via select() before reading.
Basically, the encoding code path wanted to set osdlevel=0 as default,
while normal playback needs osdlevel=1. For this purpose, osdlevel was
set to -1 (i.e. invalid) initially to detect whether the --osdlevel
option was explicitly set. When encoding was not configured
(CONFIG_ENCODING undefined), the osdlevel value was not set from
-1 to 1 properly, and the OSD remained invisible by default.
Fix this by getting rid of this logic. It shouldn't be needed, since
osdlevel=1 never shows any OSD messages without user interaction.
Should this ever change, we could still check whether encoding is in
progress, or add another option to allow OSD rendering during encoding.
cocoa_common was hiding the dock and menubar unconditionally when
going fullscreen. This means they were hidden even if they weren't on
the screen mplayer2 was going fullscreen on, resulting in poor user
experience.
Change the fullscreen function in the cocoa backend to check that
mplayer2 is on the same screen as the menubar/dock before hiding them.
Extend m_properties_expand_string() so that it can print properties as
unformatted string. Normally, properties will be pretty-printed
(intended for OSD and user interface purposes). Add the '=' modifier to
the format string syntax that disables pretty-printing and returns them
"raw".
For example, "${=switch_audio}" will print the track number, instead of
returning an OSD friendly string containing additional information like
track title and language.
This is done by requesting a buffer from the next filter in the chain, instead
of always allocating our own. This allows the next filter to e.g. ensure its
own preferred memory layout.
