Sebastian Dröge 9d3888d294 gstreamer: Fix PromiseFuture implementation
We can't return a plain reference to something stored inside the future
as that would go out of scope after `await`. Instead return a struct
that wraps the `gst::Promise`, derefs to a structure and keeps the
promise alive as long as needed.

Sebastian Dröge 7e7f358ba2 gstreamer/tags: Replace removed glib TypedValue with local TagValue
See https://github.com/gtk-rs/gtk-rs/pull/449.  This struct remains
vital in GStreamer code to tie a type to an (untyped) SendValue, so that
the underlying value can be retrieved without having to guess its type.
That type is anyway stored in a private member T::TagType.

Marijn Suijten 6ec0e3ac4b Update gir and regenerate with extended gir-dirs comments

Sebastian Dröge ea239c587e Store panic information not in a custom instance struct but in the instance data provided by the subclassing infrastructure
This scales better as there will only be only such data instead of two
or more when having deeper class hierarchies with multiple Rust
elements, and also makes it unnecessary to use a special instance struct
so the default works well.

Sebastian Dröge 932b8f813d gstreamer/pad: Add support for removing pad probes from the probe callback
While this allows to remove the pad probe multiple times, which would
cause a g_warning(), this is not actually making the situation worse
than before while making some code patterns easier to implement:

  - Probes could already be removed twice by return
    gst::PadProbeReturn::Remove and then calling pad.remove_probe()
  - Probes could be removed from a different pad than where they were
    added

As such let's go with the simple solution here for now and allow giving
owned access to the probe id from the probe callback.

Sebastian Dröge d746bf91e1 gstreamer: Provide better bindings for ElementFactoryListType
Make it an actual bitflags type instead of just an u64 alias and add all
the constants. As it's not defined as bitflags in C this needs to be
done manually.

Marijn Suijten ce67076f26 gstreamer,video: Do not zero-initialize designated struct members
This should be analogous to C struct initalizers where all unspecified
fields are initialized to zero. Without mut this reads a bit nicer as
well.

Note that two out of three structs have all members specified, hence
need no zero-initialization of the remainder at all.

Jan Alexander Steffens (heftig) 796f93f7f4 gstreamer/clock_time: Improve Display formatting
- Add support for precision, padding and alignment.
- Format the invalid time using dashes (`--:--:--.---------`) instead of
  a technically valid `99:99:99.999999999`

The latter is something C's `GST_TIME_FORMAT` can't do, though something
obviously invalid like `-1👎-1.000000000` would be possible.

Sebastian Dröge 0e8b95f1d0 urihandler: Provide URIType as associated constant when implementing the gst::URIHandler interface

must not randomly change at runtime.

directly on versions where they are supported prevents us from going
through GType machinery and locks that end up the same functions in the

Sebastian Dröge a7749b7933 gstreamer/log: Don't provide direct access to the logged object as glib::Object
It might just be constructed or might be finalized currently and it's
not safe to use any APIs on it.

Instead provide a small wrapper type that allows to get the underlying
pointer and that implements the Display trait to print the name of the
object.

François Laignel ae9d97dfca ClockTime & opt Formats: fix PartialOrd impl, remove Ord and add min & max
- `PartialOrd` was returning `true` for expressions such as
  - `ClockTime::none() < ClockTime::from_seconds(1)`.
  - `ClockTime::from_seconds(1) > ClockTime::none()`.
- Remove `Ord` because `ClockTime` is not a total order due to
  `ClockTime::none()`. See test `not_ord`.

This also applies to others `Format(Option<{u32,u64}>)` types.

Sebastian Dröge 7086a754be Add various glib::Value trait impls for borrowed versions of types
For SDPMessageRef, StructureRef and CapsFeatureRef this involves the
conversion from and to a glib::Value. Specifically this means that e.g.
a StructureRef can be retrieved from a glib::Value via borrowing, i.e.
without creating a copy of the structure first.

For all mini objects only retrieval from a glib::Value is implemented as
the other direction would allow to get multiple immutable references
from a mutable reference without borrowing, which is not allowed and
would make it possible to observe a mini object changing while having an
immutable reference to it.

Sebastian Dröge a884a419db gstreamer/buffer: Add a BufferCursor / BufferCursorRef helper structs
This implements Read/Seek or Write/Seek and allows to read/write/seek
into the buffer without merging the memories inside.

The writer also only maps the memory write-only as compared to all other
ways of accessing the buffer/memory data in a writable way, which have
to map it read-write.

See https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/425
for a similar API proposal for GStreamer core.

Sebastian Dröge b21f576430 Add #[must_use] attribute to mutex guards / stream lock
It's usually a mistake if creating one of these and immediately dropping
them again as that would immediately unlock the mutex again.

Sebastian Dröge 98ecef7153 Make sure to hold MutexGuard for the remainder of the function in various places
Not assigning it to a variable would cause it to be dropped immediately
and the lock to be released again immediately.

Sebastian Dröge d58cf01e3a Allow changing bus sync handler and appsink/src callbacks when running with 1.16.3 or newer
Previously it was not thread-safe to change them and could lead to
crashes but with 1.16.3 it is now.

Unsetting the bus sync handler before 1.16.3 will have no effect at all,
setting a new bus sync handler or appsink/src callbacks will panic.

This partially reverts 2f88dc6576

Sebastian Dröge 2f88dc6576 Only allow setting Bus sync handler and AppSrc/Sink callbacks once
Re-setting them is not thread-safe and can cause segfaults or worse.

Sebastian Dröge fe4f074e90 bus: Don't use the bus sync handler in the bus Stream to notify about messages being available
This is racy and can cause the consumer of the messages to never be
woken up anymore:

1. Waker is stored because no message on the bus
2. Sync handler is called, waker is woken up
3. Bus is polled again and no message is on it (yet),
   new waker is registered
4. Bus stores the message from 2. in its queue (after
   the sync handler has returned BusSyncReply::Pass)
5. No new message ever appears on the bus because all
   this happened for the very last message

Sebastian Dröge 63a8afafa5 gstreamer: Use more accurate types for Seqnum, GroupId and MetaSeqnum
For the latter introduce an actual opaque type that allows using them
for comparison purposes but is not just a plain u64.

For the former represent them as opaque type around an NonZeroU32. 0 is
the invalid case and does not happen in the majority of functions. Where
it can happen, represent this case by using an Option<_> instead.

This makes it harder to mis-use these types.
