Currently it is only used for video with 'interlace-mode=alternate'

to ensure backwards compatibility for this new mode.
|
|
In this mode each buffer carries a single field of interlaced video.
|
|
@GST_VIDEO_BUFFER_FLAG_TOP_FIELD and @GST_VIDEO_BUFFER_FLAG_BOTTOM_FIELD
|
|
indicate whether the buffer carries a top or bottom field. The order of

buffers/fields in the stream and the timestamps on the buffers indicate the
|
|
temporal order of the fields.
|
|
Top and bottom fields are expected to alternate in this mode.
|
|
The frame rate in the caps still signals the frame rate, so the notional field
|
|
rate will be twice the frame rate from the caps
|

(see @GST_VIDEO_INFO_FIELD_RATE_N).</doc>

|
|
<doc xml:space="preserve">The Navigation interface is used for creating and injecting navigation related
|
|
events such as mouse button presses, cursor motion and key presses. The associated
|
|
library also provides methods for parsing received events, and for sending and
|
|
receiving navigation related bus events. One main usecase is DVD menu navigation.
|
|
|
|
The main parts of the API are:
|
|
|
|
* The GstNavigation interface, implemented by elements which provide an application
|
|
with the ability to create and inject navigation events into the pipeline.
|
|
* GstNavigation event handling API. GstNavigation events are created in response to
|
|
calls on a GstNavigation interface implementation, and sent in the pipeline. Upstream
|
|
elements can use the navigation event API functions to parse the contents of received
|
|
messages.
|
|
|
|
* GstNavigation message handling API. GstNavigation messages may be sent on the message
|
|
bus to inform applications of navigation related changes in the pipeline, such as the
|
|
mouse moving over a clickable region, or the set of available angles changing.
|
|
|
|
The GstNavigation message functions provide functions for creating and parsing
|
|
custom bus messages for signaling GstNavigation changes.</doc>

|
In case of GST_VIDEO_INTERLACE_MODE_ALTERNATE info, this macro returns the
|
|
plane heights used to hold a single field, not the full frame.
|
|
|
|
The size passed as third argument is the size of the pixel data and should
|
|
not contain any extra metadata padding.
|

Notes:
|
|
|
|
1) AFD 0 is undefined for ATSC and SMPTE ST2016-1, indicating that AFD data is not available:
|
|
If Bar Data is not present, AFD '0000' indicates that exact information
|
|
is not available and the active image should be assumed to be the same as the coded frame. AFD '0000'.
|
|
AFD '0000' accompanied by Bar Data signals that the active image’s aspect ratio is narrower than 16:9,
|
|
but is not 4:3 or 14:9. As the exact aspect ratio cannot be conveyed by AFD alone, wherever possible,
|
|
AFD ‘0000’ should be accompanied by Bar Data to define the exact vertical or horizontal extent
|
|
of the active image.
|
|
2) AFD 0 is reserved for DVB/ETSI
|
|
3) values 1, 5, 6, 7, and 12 are reserved for both ATSC and DVB/ETSI
|
|
4) values 2 and 3 are not recommended for ATSC, but are valid for DVB/ETSI</doc>

<doc xml:space="preserve">This base class is for video decoders turning encoded data into raw video
|
|
frames.
|
|
|
|
The GstVideoDecoder base class and derived subclasses should cooperate as
|
|
follows:
|
|
|
|
## Configuration
|
|
|
|
* Initially, GstVideoDecoder calls @start when the decoder element
|
|
is activated, which allows the subclass to perform any global setup.
|
|
|
|
* GstVideoDecoder calls @set_format to inform the subclass of caps
|
|
describing input video data that it is about to receive, including
|
|
possibly configuration data.
|
|
While unlikely, it might be called more than once, if changing input
|
|
parameters require reconfiguration.
|
|
|
|
* Incoming data buffers are processed as needed, described in Data
|
|
Processing below.
|
|
|
|
* GstVideoDecoder calls @stop at end of all processing.
|
|
|
|
## Data processing
|
|
|
|
* The base class gathers input data, and optionally allows subclass
|
|
to parse this into subsequently manageable chunks, typically
|
|
corresponding to and referred to as 'frames'.
|
|
|
|
* Each input frame is provided in turn to the subclass' @handle_frame
|
|
callback.
|
|
The ownership of the frame is given to the @handle_frame callback.
|
|
|
|
* If codec processing results in decoded data, the subclass should call
|
|
@gst_video_decoder_finish_frame to have decoded data pushed.
|
|
downstream. Otherwise, the subclass must call
|
|
@gst_video_decoder_drop_frame, to allow the base class to do timestamp
|
|
and offset tracking, and possibly to requeue the frame for a later
|
|
attempt in the case of reverse playback.
|
|
|
|
## Shutdown phase
|
|
|
|
* The GstVideoDecoder class calls @stop to inform the subclass that data
|
|
parsing will be stopped.
|
|
|
|
## Additional Notes
|
|
|
|
* Seeking/Flushing
|
|
|
|
* When the pipeline is seeked or otherwise flushed, the subclass is
|
|
informed via a call to its @reset callback, with the hard parameter
|
|
set to true. This indicates the subclass should drop any internal data
|
|
queues and timestamps and prepare for a fresh set of buffers to arrive
|
|
for parsing and decoding.
|
|
|
|
* End Of Stream
|
|
|
|
* At end-of-stream, the subclass @parse function may be called some final
|
|
times with the at_eos parameter set to true, indicating that the element
|
|
should not expect any more data to be arriving, and it should parse and
|
|
remaining frames and call gst_video_decoder_have_frame() if possible.
|
|
|
|
The subclass is responsible for providing pad template caps for
|
|
source and sink pads. The pads need to be named "sink" and "src". It also
|
|
needs to provide information about the output caps, when they are known.
|
|
This may be when the base class calls the subclass' @set_format function,
|
|
though it might be during decoding, before calling
|
|
@gst_video_decoder_finish_frame. This is done via
|
|
@gst_video_decoder_set_output_state
|
|
|
|
The subclass is also responsible for providing (presentation) timestamps
|
|
(likely based on corresponding input ones). If that is not applicable
|
|
or possible, the base class provides limited framerate based interpolation.
|
|
|
|
Similarly, the base class provides some limited (legacy) seeking support
|
|
if specifically requested by the subclass, as full-fledged support
|
|
should rather be left to upstream demuxer, parser or alike. This simple
|
|
approach caters for seeking and duration reporting using estimated input
|
|
bitrates. To enable it, a subclass should call
|
|
@gst_video_decoder_set_estimate_rate to enable handling of incoming
|
|
byte-streams.
|
|
|
|
The base class provides some support for reverse playback, in particular
|
|
in case incoming data is not packetized or upstream does not provide
|
|
fragments on keyframe boundaries. However, the subclass should then be
|
|
prepared for the parsing and frame processing stage to occur separately
|
|
(in normal forward processing, the latter immediately follows the former),
|
|
The subclass also needs to ensure the parsing stage properly marks
|
|
keyframes, unless it knows the upstream elements will do so properly for
|
|
incoming data.
|
|
|
|
The bare minimum that a functional subclass needs to implement is:
|
|
|
|
* Provide pad templates
|
|
* Inform the base class of output caps via
|
|
@gst_video_decoder_set_output_state
|
|
|
|
* Parse input data, if it is not considered packetized from upstream
|
|
Data will be provided to @parse which should invoke
|
|
@gst_video_decoder_add_to_frame and @gst_video_decoder_have_frame to
|
|
separate the data belonging to each video frame.
|
|
|
|
* Accept data in @handle_frame and provide decoded results to
|
|
@gst_video_decoder_finish_frame, or call @gst_video_decoder_drop_frame.</doc>

|
|
<doc xml:space="preserve">This base class is for video encoders turning raw video into
|
|
encoded video data.
|
|
|
|
GstVideoEncoder and subclass should cooperate as follows.
|
|
|
|
## Configuration
|
|
|
|
* Initially, GstVideoEncoder calls @start when the encoder element
|
|
is activated, which allows subclass to perform any global setup.
|
|
* GstVideoEncoder calls @set_format to inform subclass of the format
|
|
of input video data that it is about to receive. Subclass should
|
|
setup for encoding and configure base class as appropriate
|
|
(e.g. latency). While unlikely, it might be called more than once,
|
|
if changing input parameters require reconfiguration. Baseclass
|
|
will ensure that processing of current configuration is finished.
|
|
* GstVideoEncoder calls @stop at end of all processing.
|
|
|
|
## Data processing
|
|
|
|
* Base class collects input data and metadata into a frame and hands
|
|
this to subclass' @handle_frame.
|
|
|
|
* If codec processing results in encoded data, subclass should call
|
|
@gst_video_encoder_finish_frame to have encoded data pushed
|
|
downstream.
|
|
|
|
* If implemented, baseclass calls subclass @pre_push just prior to
|
|
pushing to allow subclasses to modify some metadata on the buffer.
|
|
If it returns GST_FLOW_OK, the buffer is pushed downstream.
|
|
|
|
* GstVideoEncoderClass will handle both srcpad and sinkpad events.
|
|
Sink events will be passed to subclass if @event callback has been
|
|
provided.
|
|
|
|
## Shutdown phase
|
|
|
|
* GstVideoEncoder class calls @stop to inform the subclass that data
|
|
parsing will be stopped.
|
|
|
|
Subclass is responsible for providing pad template caps for
|
|
source and sink pads. The pads need to be named "sink" and "src". It should
|
|
also be able to provide fixed src pad caps in @getcaps by the time it calls
|
|
@gst_video_encoder_finish_frame.
|
|
|
|
Things that subclass need to take care of:
|
|
|
|
* Provide pad templates
|
|
* Provide source pad caps before pushing the first buffer
|
|
* Accept data in @handle_frame and provide encoded results to
|
|
@gst_video_encoder_finish_frame.
|
|
|
|
|
|
The #GstVideoEncoder:qos property will enable the Quality-of-Service
|
|
features of the encoder which gather statistics about the real-time
|
|
performance of the downstream elements. If enabled, subclasses can
|
|
use gst_video_encoder_get_max_encode_time() to check if input frames
|
|
are already late and drop them right away to give a chance to the
|
|
pipeline to catch up.</doc>

#GstVideoCodecState.
|
|
|
|
If the subclass wishes to copy over existing fields (like pixel aspect ratio,
|
|
or framerate) from an existing #GstVideoCodecState, it can be provided as a
|
|
@reference.
|
|
|
|
If the subclass wishes to override some fields from the output state (like
|
|
pixel-aspect-ratio or framerate) it can do so on the returned #GstVideoCodecState.
|
|
|
|
The new output state will only take effect (set on pads and buffers) starting
|
|
from the next call to #gst_video_encoder_finish_frame().</doc>

This function operates on pack_lines lines, meaning that @src should

pixels in a generic way, without you having to worry too much about details

such as whether the video data is allocated in one contiguous memory chunk
|
|
or multiple memory chunks (e.g. one for each plane); or if custom strides
|
|
and custom plane offsets are used or not (as signalled by GstVideoMeta on
|
|
each buffer). This function will just fill the #GstVideoFrame structure
|
|
with the right values and if you use the accessor macros everything will
|
|
just work and you can access the data easily. It also maps the underlying

memory chunks for you.</doc>

|
<doc xml:space="preserve">The #GstVideoOverlay interface is used for 2 main purposes :
|
|
|
|
* To get a grab on the Window where the video sink element is going to render.
|
|
This is achieved by either being informed about the Window identifier that
|
|
the video sink element generated, or by forcing the video sink element to use
|
|
a specific Window identifier for rendering.
|
|
* To force a redrawing of the latest video frame the video sink element
|
|
displayed on the Window. Indeed if the #GstPipeline is in #GST_STATE_PAUSED
|
|
state, moving the Window around will damage its content. Application
|
|
developers will want to handle the Expose events themselves and force the
|
|
video sink element to refresh the Window's content.
|
|
|
|
Using the Window created by the video sink is probably the simplest scenario,
|
|
in some cases, though, it might not be flexible enough for application
|
|
developers if they need to catch events such as mouse moves and button
|
|
clicks.
|
|
|
|
Setting a specific Window identifier on the video sink element is the most
|
|
flexible solution but it has some issues. Indeed the application needs to set
|
|
its Window identifier at the right time to avoid internal Window creation
|
|
from the video sink element. To solve this issue a #GstMessage is posted on
|
|
the bus to inform the application that it should set the Window identifier
|
|
immediately. Here is an example on how to do that correctly:
|
|
|[
|
|
static GstBusSyncReply
|
|
create_window (GstBus * bus, GstMessage * message, GstPipeline * pipeline)
|
|
{
|
|
// ignore anything but 'prepare-window-handle' element messages
|
|
if (!gst_is_video_overlay_prepare_window_handle_message (message))
|
|
return GST_BUS_PASS;
|
|
|
|
win = XCreateSimpleWindow (disp, root, 0, 0, 320, 240, 0, 0, 0);
|
|
|
|
XSetWindowBackgroundPixmap (disp, win, None);
|
|
|
|
XMapRaised (disp, win);
|
|
|
|
XSync (disp, FALSE);
|
|
|
|
gst_video_overlay_set_window_handle (GST_VIDEO_OVERLAY (GST_MESSAGE_SRC (message)),
|
|
win);
|
|
|
|
gst_message_unref (message);
|
|
|
|
return GST_BUS_DROP;
|
|
}
|
|
...
|
|
int
|
|
main (int argc, char **argv)
|
|
{
|
|
...
|
|
bus = gst_pipeline_get_bus (GST_PIPELINE (pipeline));
|
|
gst_bus_set_sync_handler (bus, (GstBusSyncHandler) create_window, pipeline,
|
|
NULL);
|
|
...
|
|
}
|
|
]|
|
|
|
|
## Two basic usage scenarios
|
|
|
|
There are two basic usage scenarios: in the simplest case, the application
|
|
uses #playbin or #playsink or knows exactly what particular element is used
|
|
for video output, which is usually the case when the application creates
|
|
the videosink to use (e.g. #xvimagesink, #ximagesink, etc.) itself; in this
|
|
case, the application can just create the videosink element, create and
|
|
realize the window to render the video on and then
|
|
call gst_video_overlay_set_window_handle() directly with the XID or native
|
|
window handle, before starting up the pipeline.
|
|
As #playbin and #playsink implement the video overlay interface and proxy
|
|
it transparently to the actual video sink even if it is created later, this
|
|
case also applies when using these elements.
|
|
|
|
In the other and more common case, the application does not know in advance
|
|
what GStreamer video sink element will be used for video output. This is
|
|
usually the case when an element such as #autovideosink is used.
|
|
In this case, the video sink element itself is created
|
|
asynchronously from a GStreamer streaming thread some time after the
|
|
pipeline has been started up. When that happens, however, the video sink
|
|
will need to know right then whether to render onto an already existing
|
|
application window or whether to create its own window. This is when it
|
|
posts a prepare-window-handle message, and that is also why this message needs
|
|
to be handled in a sync bus handler which will be called from the streaming
|
|
thread directly (because the video sink will need an answer right then).
|
|
|
|
As response to the prepare-window-handle element message in the bus sync
|
|
handler, the application may use gst_video_overlay_set_window_handle() to tell
|
|
the video sink to render onto an existing window surface. At this point the
|
|
application should already have obtained the window handle / XID, so it
|
|
just needs to set it. It is generally not advisable to call any GUI toolkit
|
|
functions or window system functions from the streaming thread in which the
|
|
prepare-window-handle message is handled, because most GUI toolkits and
|
|
windowing systems are not thread-safe at all and a lot of care would be
|
|
required to co-ordinate the toolkit and window system calls of the
|
|
different threads (Gtk+ users please note: prior to Gtk+ 2.18
|
|
`GDK_WINDOW_XID` was just a simple structure access, so generally fine to do
|
|
within the bus sync handler; this macro was changed to a function call in
|
|
Gtk+ 2.18 and later, which is likely to cause problems when called from a
|
|
sync handler; see below for a better approach without `GDK_WINDOW_XID`
|
|
used in the callback).

<doc xml:space="preserve">Functions to create and handle overlay compositions on video buffers.
|
|
|
|
An overlay composition describes one or more overlay rectangles to be
|
|
blended on top of a video buffer.
|
|
|
|
This API serves two main purposes:
|
|
|
|
* it can be used to attach overlay information (subtitles or logos)
|
|
to non-raw video buffers such as GL/VAAPI/VDPAU surfaces. The actual
|
|
blending of the overlay can then be done by e.g. the video sink that
|
|
processes these non-raw buffers.
|
|
|
|
* it can also be used to blend overlay rectangles on top of raw video
|
|
buffers, thus consolidating blending functionality for raw video in
|
|
one place.
|
|
|
|
Together, this allows existing overlay elements to easily handle raw
|
|
and non-raw video as input in without major changes (once the overlays
|
|
have been put into a #GstVideoOverlayComposition object anyway) - for raw
|
|
video the overlay can just use the blending function to blend the data
|
|
on top of the video, and for surface buffers it can just attach them to
|
|
the buffer and let the sink render the overlays.</doc>
