Unfortunately I'm also adding the full text of the LGPL license text,
because the GPL one was already present in this repository, and I don't
want to imply that the GPL somehow has priority.
Every compositor (including toy compositors) has had support for wl_output v2
since forever, so there's little point in supporting degraded output for 5 year
old releases (especially considering we require zxdg6 which is far more recent).
This adds symbol information to the generated SPIR-V, which shows up in
the SPIR-V assembly dump. It's also useful for potential RA backends
that use SPIRV-Cross, since the symbol information is used in the
generated shader source.
Rename --enable-preliminary-lgpl2 to --enable-gpl. This concludes the
relicensing. Some things are still to do (relicensing some still-GPL
optional code), but we consider the code included by --enable-gpl to be
fully relicensed.
The relicensing was performed by asking every known author for
permission for relicensing it to LGPL version 2.1 "or later". If an
author could not be contacted or permission could not be obtained, and
the contribution was considered relevant for copyright purposes, the
affected code was either excluded from LGPL mode (not built), or removed
or rewritten. This is the standard in open source relicensing processes.
Keep in mind that using LGPL mode is still on the user's own risk. Even
though I claim that the relicensing was pretty clean and thorough
(measured on the standards of the open source community¹), and I
followed the advice of some actual experts, there is still a residual
uncertainty due to the fact that I'm not an all-knowing entity (authors
could have taken someone else's code and pretend it's their own) nor a
lawyer (meaning I might lack associated authority or expertise), and the
fact that the judicial system is far from deterministic. The relicensing
was performed merely to the best of my knowledge. I reject all
responsibility outside of that.
This commit also cleans up the "Copyright" file to reflect the finalized
relicensing process.
¹ Not to imply that the standards of commercial companies are much
higher. Some major tech companies get away with stuff I would not
consider clean.
See #2033.
This should actually cover all of them, if you take into account that
some unchanged GPL source files include header files with such checks.
Also this was done already for the libaf derived code.
This is only for "safety" and to avoid misunderstandings.
It turns out compositors which do scaling scale the cursor as well,
so every single surface needs to get scaled too.
Also, 32 corresponds to the default size for both GTK+ and KDE.
This new interface in libva2 offers a cleaner way to export surfaces
which can then be imported to EGL. In particular, this works with
the Mesa driver, so we can have proper playback without a pointless
download and upload on AMD cards.
This change does nothing with libva1, and will fall back to the
libva1 interface (vaDeriveImage() + vaAcquireBufferHandle()) if
vaExportSurfaceHandle() is not present.

Rename --stats to --load-stats-overlay and add an entry to options.rst
over the original commit.

Previously multiple timers were used to realize oneshot, toggling
(redrawing) and page keybindings. The oneshot case in particular also
relied on mp.osd_message to display text only for a given duration.
This was changed to only use one timer in total now. Because now each
case has a defined "start" and "end" point (including oneshot)
mp.set_osd_ass() can be used to print stats as well. This is currently
optional and has to be activated using the config option
persistent_overlay=true.
One shortcoming: oneshot and toggling are mutual exclusive right now.
Previously you could enter toggling while oneshot stats were shown,
this is not possible anymore to reduce the number of cases to be
considered. This can be added later on if desired.
It used a bad heuristic that got even worse/less reliable with recent
changes in mpv. In fact, it's not reliable at all.
Watch out for dropped frames instead. That's a useful indicator.
Previously I could trigger a bug with intense button mashing, however,
was unable to reproduce it and therefore debug it.
This change now seems to be resilient against button mashing, let's hope
it really is.
Please note that the latest version of this script needs a very recent
version of mpv (from yesterday, to be precise, see the readme).
For older versions, please go to "releases".
HOW IT WORKS:
While the stats are visible (i.e. text is printed to the OSD) a
subsequent click on a numeric key (1, 2, ...) will display the
corresponding "page".
This works no matter if the stats are toggled or just shown as a single
invocation. In case of a single invocation, the newly displayed page
will be shown for the full duration again.
The selected page will be remembered (not persistantly though).
So far, only 3 pages are available.
1: the default page, stats as they used to be
2: extensive VO performance stats (to be redesigned/changed soon)
3: dummy
In the future, many more pages are possible.
Implementation is likely to change again (functionality will stay
the same). A new timer had to be introduced to remove the forced
keybindings in the oneshot case. The toggle case can remove them without
a timer. Ensuring that each mode won't remove timers of the other mode
didn't really turn out neat.
Therefore, I intend to change this again, maybe by merging the
oneshot case into the toggle case.
Due to the large amount of per-pass data, the function takes a parameter
indicating whether or not to print a simplified view instead.
The overall intent is to print the simplified view for now, but supposed
printing the full view on a dedicated "tab" (or extra view type), and as
such, `o.print_perfdata_passes` will go away again. I've only introduced
it for now so users can play around with this functionality if they want
to, until Argon- gets around to implementing stats "tabs".
Previously, we used a property and when it was unavailable we assumed it
doesn't exist before assuming it really is just unavailable. This lead
to unnecessarily falling back to deprecated properties which made mpv
print deprecation warnings.
Now we can really check if a property is not known to mpv.
The alternative would've been to check the error part of mp.get_property
and perform string comparisons on the returned error message.
Not sure if supporting old mpv versions is actually worth it though.
