b005d472f7 video: fix doc warning
@mode has been renamed to
gst_video_decoder_set_interlaced_output_state() but not in the header
file, raising a doc warning.

d26eede464 videodecoder: Add API for subclasses to request a new sync point
This allows subclasses that notice missing reference frames to request a
new sync point to allow seamless decoding again. While doing so the
subclass can also signal whether it wants a) all following input frames
until the sync point to be discarded or b) all output frames until the
sync point to be marked as corrupt.

Sending of force-keyunit events for this can be throttled by the
application via the "min-force-keyunit-interval" property.

This replaces custom behaviour for the same in various decoders, for
example openh264dec.

Based on patches by Haakon Sporsheim <haakon@pexip.com> and
Stian Selnes <stian@pexip.com>.

fdf79a786c videodecoder: Add API for subclasses to signal that they need the stream to start with a sync point
If the first frame(s) at the very beginning or after a flush are not a
sync point then the base class would discard them before passing them to
the subclass.

This also fixes the previously broken distance_from_sync handling: it
was never reset at sync points.

93daa1435a Use G_DEFINE_AUTOPTR_CLEANUP_FUNC unconditionally
Since we started depending on GLib 2.44, we can be sure this macro is
defined (it will be a no-op on compilers that don't support it). For
plugins we should just start using `G_DECLARE_FINAL_TYPE` which means we
no longer need the macro there, but for most types in base/gst-libs we
don't want to break ABI, which means it's better to just keep it like it
is (and use the `#ifdef` instead).

be6c8400b0 video: Add gst_video_decoder_set_interlaced_output_state()
Add a variant of gst_video_decoder_set_output_state() that allows the user
to pass an interlacing mode as well. This is needed to ensure that
gst_video_info_set_interlaced_format() is used instead so that
GstVideoInfo.size is correctly initialized.

ae429de8f6 video: GST_EXPORT -> GST_VIDEO_API
We need different export decorators for the different libs.
For now no actual change though, just rename before the release,
and add prelude headers to define the new decorator to GST_EXPORT.

3bf893e12a video: add gst_video_decoder_allocate_output_frame_with_params
It adds a third argument to pass GstBufferPoolAcquireParams
to gst_buffer_pool_acquire_buffer.

If a user subclasses GstBufferPoolAcquireParams, this allows to
pass an updated param to the underlying buffer pool at each
gst_video_decoder_allocate_output_frame_with_params call.

c63db0e104 Revert "videodecoder: expose default query handling function"
Apparently I forgot how gobject works, there is no need to expose
it directly as one can call it from the parent_class pointer

4982188cf7 videodecoder: add option to use default pad accept-caps handling
Add gst_video_decoder_set_use_default_pad_acceptcaps() to allow
subclasses to make videodecoder use the default pad acceptcaps
handling instead of resorting to the caps query that is, usually,
less efficient and unecessary

d2cc76b228 videodecoder: Add transform_meta() vfunc with default implementation
The default implementation copies all metadata without tags, and metadata
with only the video tag. Same behaviour as in GstVideoFilter.

This currently does not work if the ::parse() vfunc is implemented as all
metas are getting lost inside GstAdapter.

efe9e31b34 videodecoder: getters for pool and allocator
Sometimes the decoder would need to use the pool or the allocator for
something else than just allocating output buffers. For example, the querying
for different parameters, such as asking for a bigger number of buffers to
allocate in the pool.

This patch expose a two getters accessors: one for the buffer pool and the
other for the memory allocator.
