This has two goals:
1. Getting rid of global variables to make the core library-safe.
2. Getting rid of all the MSGT_* constants and the inconsistent
prefixes spread throughout the source code.
Both goals are not immediately reached with this commit. It's a huge
transition that will take time. There are over >2500 mp_msg calls in the
source, which all have to be replaced for this to work.
The inconsistent prefixes are in particular annoying. Lots of code
manually prefixes messages, e.g. mp_msg(MSGT_VO, MSGL_V, "[vo] ...").
Sometimes the prefixes don't even follow this convention (for example
vo_direct3d.c uses "<vo_direct3d>" as prefix). This commit allows
automatically adding prefixes on request, so consistency will
hopefully improve.
For now, this commit adds unused stuff, and behavior should not change.
In mplayer.c, move the GetCpuCaps() call, because that used mp_msg()
before mp_msg_init() was run.
The -vo/-ao options support skipping of unknown entries for the sake of
allowing using the same config on possibly very different systems, which
have different sets of VO/AOs available.
Unfortunately skipping didn't quite work, possibly a rebase error when
this was originally committed. Fix it.
We don't need to store anymore whether an option is aliased by another
option (which is what the alias_owner member did). Also, that member
had a really bad name.
This also removes some unneeded code from config_destroy(). Calling
m_option_free() is always ok; this just skipped the call if it did
nothing. In particular, it's ok to call m_option_free() on the same
pointer multiple times. (Maybe that function is misnamed, and it should
be m_option_clear().)
File local options need to backup the global option value while a file
is played. Instead of keeping a pointer in m_config_option for the
backup value, put it into a separate list. This reduces per-option
overhead for a rarely used obscure feature. (This implementation would
have been a bit dumb in pre-mpv m_config, because there local options
were the default, and _all_ options were backed up when starting
playback of a file. This is not the case anymore, and normally only
a very small number of options are backed up by default.)
This introduces some changes in resize behaviour. Most importantly the window
frame is not constrained to it's screen's `visibleFrame`. Anyone who still wants
that kind of behaviour when opening a video, can use `--autofit-larger`.
Even though the size of the window is not constrained, it's position is, so
that the titlebar will always be visible. When using `--no-border` even the
position will not be constrained in any way.
CONFIG_VDPAU was just defined to 0, instead of undefined when vdpau was
unavailable. I blame the old mplayer code, which apparently can't have
consistent conventions.
The check for HAVE_AV_CODEC_NEW_VDPAU_API just determines whether the
new vdpau libavutil pixel format is available (which implies presence of
the new API). However, that pixel format (and the correspondig config
test define) is also used in generic code (compiled even without vdpau)
in fmt-conversion.c. Since the configure test didn't define the symbol
if vdpau was not available, it broke in this case.
The URL option parser only accesses certain fields. Remove the fields
that are not accessed, and thus are completely unused and inaccessible.
Historically, these fields were supposed to be settable using an extra
list of options passed to open_stream(). Commit f518cf7 removed these
extra options. Apparently nothing ever actually used this facility.
Using the default output audio unit should provide a much better user
exeperience since it changes automatically the output device based on which
becomes the default one.
Instead of generating vdpau_template.c with a Perl script, just include
the generated file in git. This is ok because it changes very rarely,
and the script is larger than the output it generates.
It also simplify the Makefile, and fixes the build. The problem was that
transitive dependencies do not work with generated files: there is no
dependency information yet when building it the first time. I overlooked
this because I didn't delete the .d files for testing (which contained
the correct dependencies, but only _after_ a first successful build).
Move the decoder parts from vo_vdpau.c to a new file vdpau_old.c. This
file is named so because because it's written against the "old"
libavcodec vdpau pseudo-decoder (e.g. "h264_vdpau").
Add support for the "new" libavcodec vdpau support. This was recently
added and replaces the "old" vdpau parts. (In fact, Libav is about to
deprecate and remove the "old" API without deprecation grace period,
so we have to support it now. Moreover, there will probably be no Libav
release which supports both, so the transition is even less smooth than
we could hope, and we have to support both the old and new API.)
Whether the old or new API is used is checked by a configure test: if
the new API is found, it is used, otherwise the old API is assumed.
Some details might be handled differently. Especially display preemption
is a bit problematic with the "new" libavcodec vdpau support: it wants
to keep a pointer to a specific vdpau API function (which can be driver
specific, because preemption might switch drivers). Also, surface IDs
are now directly stored in AVFrames (and mp_images), so they can't be
forced to VDP_INVALID_HANDLE on preemption. (This changes even with
older libavcodec versions, because mp_image always uses the newer
representation to make vo_vdpau.c simpler.)
Decoder initialization in the new code tries to deal with codec
profiles, while the old code always uses the highest profile per codec.
Surface allocation changes. Since the decoder won't call config() in
vo_vdpau.c on video size change anymore, we allow allocating surfaces
of arbitrary size instead of locking it to what the VO was configured.
The non-hwdec code also has slightly different allocation behavior now.
Enabling the old vdpau special decoders via e.g. --vd=lavc:h264_vdpau
doesn't work anymore (a warning suggesting the --hwdec option is
printed instead).
See previous commits. This time, the lock is kept for rather long
times (e.g. for the duration of a big image memory allocation), but
this (probably) still doesn't matter at all.
This also affects legacy code only (pre-refcounting libavcodec).
See previous commits. Also simplify this thing: 2 flags per pool image
are enough to avoid a weird central refcount and an associated shared
object keeping the refcount. We could even just store these two flags
in the mp_image itself (like in mp_image.flags or mp_image.priv), but
let's not for the sake of readability.
This hasn't been done yet, because pthreads is still an optional
dependency, so this is a bit annoying. Now doing it anyway, because
maybe we will need this capability in the future.
We keep it as simple as possible. We (probably) don't need anything
more sophisticated, and keeping it simple avoids introducing weird
bugs. So, no atomic instructions, no fine grained locks, no cleverness.
All these --no-... options in --list-options made the output rather
unreadable, so hide them. Make the code for finding positional
parameters (which are supposed to skip these no-* options) slightly
simpler too.
Do this by recreating the m_config from scratch, which then must
contain the default values. This doesn't quite work with legacy options
using global variables: the default values get lost, so using
--list-options will print the value as set by the config file. This
also introduces a memory leak for string options backed by global
variables. All of these issues will be eventually fixed by moving all
options to structs.
Change how m_config is initialized. Make it more uniform; now all
m_config structs are intialized in exactly the same way. Make sure
there's only a single m_option[] array defining the options, and keep
around the pointer to the optstruct default value, and the optstruct
size as well. This will allow reconstructing the option default values
in the following commit.
In particular, stop pretending that the handling of some special options
(like --profile, --v, and some others) is in any way elegant, and make
them explicit hacks. This is really more readable and easier to
understand than what was before, and simplifies the code.
Prevents some awkwardness in a later commit, and makes the code more
uniform with other places where MPOpts is accessed.
This is a pretty annoying commit (touches tons of lines all over the
place), but it hurts only once.
This change affects vf_lavfi. Until recently, libavfilter was not
colorspace aware at all. This changed with the addition of colorspace
fields to AVFrame. libavfilter's vf_scale picks them up (as of recent
ffmpeg git). Since this support is still kind of wonky and not part of
the normal format negotiation, this won't set the correct output
colorspace, though.
Not adding a separate test for HAVE_AVFRAME_COLORSPACE. This is slightly
unclean, but on the other hand adding an explicit test seems like a
waste of effort.
The symptom was that "-vf scale,format=rgba" broke the vsfilter
colorspace hack in sd_ass. vf->reconfig is allowed to overwrite its
input parameter for convenience (maybe that was a bad idea).
This was removed in d427b4fd. I now found a sample that causes underruns when
moving to a chapter and apparently this is also a problem when taking
screenshots.
Reverts one of the changes from 18777ecf. `kAudioObjectPropertyScopeOutput`
was introduced in the 10.8 SDK while `kAudioDevicePropertyScopeOutput` was
moved to `AudioHardwareDeprecated.h`. Since the deprecation is silent for now
(no warnings), just use the old constant.
Either way, they both evaluate to 'outp', and in the 10.8 SDK the deprecated
constant is defined in terms of the non-deprecated one.
Fixes#155
Fixes reports of printing of garbage (or anything else) other than clearing
the status line to the end of line: the buffer returned by termcap_get
could get moved, and if that happened then these 3 caps pointed to garbage.
setupterm abort()s if it can't initialize the terminal and the last
parameter is NULL; handle setupterm errors and retry with "ansi" if
the TERM env var was unset.
Remove the (now unused) code for determining correct-pts mode based on
the demuxer in use. Change its description in the manpage to reflect
what this option does now.
Due to the termcap matching and the hardcoded fallbacks, the ESC keypress
has to be followed by another non-matching keypress (such as another ESC)
for it to be accepted. We drop the second ESC in case it was typed twice.
On Linux, the check fails because NULL is not defined. Fix by using 0
instead, which is a perfectly valid null pointer constant, but doesn't
require stddef.h.
