The aim here is to stream an online video/audio while also at the
same time download/cache it to disk (excluding adaptive content).
After download is complete, further playback and seeking are done using the
locally cached file. This functionality uses GStreamer "downloadbuffer" element.
Player will emit a signal with a local download location after it completes,
so application will know where downloaded file for media item is stored in
case it wants to reuse it in the future.
It is up to application to set download dir and later manage downloaded
content in it, removing files its not going to use on next application
run and any incomplete downloads.
Billboard does not post automatic volume/speed announcements. It did at
some point during development, but it was scrapped in favour of letting
app use callbacks of "notify" signals to call announce speed/volume.
It seems GTK continues using created contexts, so we cannot unref it here.
Looking at GTK sink implementation for GtkVideo, I see that they do not
unref it either, but since we use surfaceless context it would be probably
better to have a static GstDisplay and reuse the same context in future.
Some media files have custom/proprietary metadata.
It should be safe to simply ignore these, since we do
not map metadata to any sort of Clapper stream anyway.
Fixes#441
GStreamer 1.24 have implemented DRM modifiers negotiation that its lack of we were
working around with using GL on unpatched GStreamer (non-Flatpak builds).
Since GStreamer 1.24 does this and moreover it has disabled DMABuf codepath for
non-GLES we should start preferring GLES with this version always.
This patch modifies the initialization routines of clapper to check for
CLAPPER_GTK_OVERRIDE_LOCALEDIR and
CLAPPER_APP_OVERRIDE_LOCALEDIR
and uses that instead of the LOCALEDIR specified in the config.h.
It also fixes the bug where libclapper-gtk loads the translations for
the clapper application and the clapper application loads the
translations for the libclapper-gtk. (It took me shockingly long to
figure out why the translations weren't working 🙃)

Try to parse into a number as much of the string as possible, without caring
about a sign suffix. This way input will be more forgiving instead of resetting
itself to lowest allowed number.
Also when a number exceeds allowed range, set it to maximal allowed value
instead of once again resetting to minimum.
When creating JSON data, we must ensure that our decimal numbers are converted
to a string with a "." as separator, otherwise it would be an invalid JSON.
As the SpinButton input callback attempted to parse the value inserted
as a string by printf using g_ascii_strtod, only if the language also
used . (full stop / u002E) as decimal seperator worked correctly.
Otherwise, parsing would fail and result (after a few iterations) in the
lowest value being set.
The usually correct approach is to use g_ascii_dtostr / g_ascii_formatd
instead of printf to format a decimal number, but given that this number
is actually presented to the user, going with g_strtod seems like a
better choice (I've decided against just using the stdlib strtod as to
allow the SpinButton to also recognize manual user input containing the
full stop instead of their languages native decimal seperator (not
that that'll ever happen, given the user can't focus the SpinButton
entry while media is running).
I've also fixed this for the volume SpinButton too, but it wasn't really
affected in the first place as it appearently always gets rounded up to
a number without decimal places.

Since we only do seek on scale drop, handle scrubbing using touchpad
the same way by marking it as "dragging" after scrubbing starts and
doing seek after it ends.
An easy to use GTK integration library. Meant as a GtkVideo alternative.
While GtkVideo is more of a simple example of video playback under GTK4, this
acts as a full-fledged video player in the form of a GtkWidget that can be placed
anywhere within application.
The widget offers customization options for both top header and bottom playback
controls panels. The Clapper playback API is exposed under widget "player" property
making it easy for the programmer to set media and control playback programically.
The new library will be distributed with Clapper player. This includes public headers
and GObject Introspection support.
Licensed under LGPL-2.1-or-later.
An easy to use media playback library (libclapper) as a GstPlayer replacement.
Previously we tried to use upstream `gstplayer` library to control playback and
pass all events from multiple threads GStreamer uses into an app main thread.
Since this caused some thread racy problems and we needed additional ABI breaking
changes to better suit our needs, we ended up with a modified fork of said library
renamed to `gstclapper` as a temporary solution.
This new library simply named `clapper` replaces our previous `gstclapper` solution
and is written completely from scratch by myself. The aim here is to have an easy to
use playback library better suited to work with (but not limited to) GTK and GObject
properties bindings by relying on "notify" signals.
Major differences include:
* Operates on a playback queue (inherits `GListModel` interface) instead of a single URI
* Uses "notify" signals for property changes always dispatched to app thread
* Time is passed/read as decimal number in seconds instead of int64 in nanoseconds
* Integrates `GstDiscoverer` to figure out media info (such as title) before playback
* Easy to use MPRIS support as part of library
* Optional playback remote controls with WebSocket messages
The new library will be distributed with Clapper player. This includes public headers
and GObject Introspection support.
