We get loads of warnings when parsing videos from users: gsth264parser.c:1115:gst_h264_parser_parse_user_data_unregistered: No more remaining payload data to store gsth264parse.c:646:gst_h264_parse_process_sei:<h264parse0> failed to parse one or more SEI message Those are raised because of unregistered SEI without user data. The spec does not explicitly state that unregistered SEI needs to have data and I suppose the UUID by itself can carry valuable information. FFmpeg also parses and exposes such SEI so there is no reason for us no too as well. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/7931>

In this mode each buffer carries a single field of interlaced video.

|
|
<doc xml:space="preserve" filename="../subprojects/gst-plugins-base/gst-libs/gst/video/navigation.c">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>

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" filename="../subprojects/gst-plugins-base/gst-libs/gst/video/gstvideodecoder.c">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.
|
|
* When the subclass enables the subframe mode with `gst_video_decoder_set_subframe_mode`,
|
|
the base class will provide to the subclass the same input frame with
|
|
different input buffers to the subclass @handle_frame
|
|
callback. During this call, the subclass needs to take
|
|
ownership of the input_buffer as @GstVideoCodecFrame.input_buffer
|
|
will have been changed before the next subframe buffer is received.
|
|
The subclass will call `gst_video_decoder_have_last_subframe`
|
|
when a new input frame can be created by the base class.
|
|
Every subframe will share the same @GstVideoCodecFrame.output_buffer
|
|
to write the decoding result. The subclass is responsible to protect
|
|
its access.
|
|
|
|
* If codec processing results in decoded data, the subclass should call
|
|
@gst_video_decoder_finish_frame to have decoded data pushed
|
|
downstream. In subframe mode
|
|
the subclass should call @gst_video_decoder_finish_subframe until the
|
|
last subframe where it should call @gst_video_decoder_finish_frame.
|
|
The subclass can detect the last subframe using GST_VIDEO_BUFFER_FLAG_MARKER
|
|
on buffers or using its own logic to collect the subframes.
|
|
In case of decoding failure, the subclass must call
|
|
@gst_video_decoder_drop_frame or @gst_video_decoder_drop_subframe,
|
|
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>

a new sync should be requested from upstream, and that @frame was the frame
|
|
when the subclass noticed that a new sync point is required. A reason for
|
|
the subclass to do this could be missing reference frames, for example.
|
|
|
|
The base class will then request a new sync point from upstream as long as

the time that passed since the last one is exceeding
|
|
#GstVideoDecoder:min-force-key-unit-interval.
|
|
|
|
The subclass can signal via @flags how the frames until the next sync point
|
|
should be handled:
|
|
|
|
* If %GST_VIDEO_DECODER_REQUEST_SYNC_POINT_DISCARD_INPUT is selected then
|
|
all following input frames until the next sync point are discarded.
|
|
This can be useful if the lack of a sync point will prevent all further
|
|
decoding and the decoder implementation is not very robust in handling
|
|
missing references frames.
|
|
* If %GST_VIDEO_DECODER_REQUEST_SYNC_POINT_CORRUPT_OUTPUT is selected
|
|
then all output frames following @frame are marked as corrupted via
|
|
%GST_BUFFER_FLAG_CORRUPTED. Corrupted frames can be automatically
|
|
dropped by the base class, see #GstVideoDecoder:discard-corrupted-frames.
|
|
Subclasses can manually mark frames as corrupted via %GST_VIDEO_CODEC_FRAME_FLAG_CORRUPTED

can receive the data at a granularity lower than one frame.
|
|
|
|
Note that in this mode, the subclass has two options. It can either
|
|
require the presence of a GST_VIDEO_BUFFER_FLAG_MARKER to mark the
|
|
end of a frame. Or it can operate in such a way that it will decode
|
|
a single frame at a time. In this second case, every buffer that
|
|
arrives to the element is considered part of the same frame until
|
|
gst_video_decoder_finish_frame() is called.
|
|
|
|
In either case, the same #GstVideoCodecFrame will be passed to the
|
|
GstVideoDecoderClass:handle_frame vmethod repeatedly with a
|
|
different GstVideoCodecFrame:input_buffer every time until the end of the
|
|
frame has been signaled using either method.

<doc xml:space="preserve" filename="../subprojects/gst-plugins-base/gst-libs/gst/video/gstvideoencoder.c">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.

|
|
|
* 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>

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

contain at least pack_lines lines with a stride of @sstride and @y

Subsampled formats will use the horizontally and vertically cosited

packing.

Because this function does not have a x coordinate, it is not possible to

pack pixels starting from an unaligned position. For tiled images this

means that packing should start from a tile coordinate. For subsampled

The purpose of this function is to make it easy for you to get to the video
|
|
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>

|
|
|
This meta can also be used by downstream elements to specifiy their
|
|
buffer layout requirements for upstream. Upstream should try to
|
|
fit those requirements, if possible, in order to prevent buffer copies.
|
|
|
|
This is done by passing a custom #GstStructure to
|
|
gst_query_add_allocation_meta() when handling the ALLOCATION query.
|
|
This structure should be named 'video-meta' and can have the following
|
|
fields:
|
|
- padding-top (uint): extra pixels on the top
|
|
- padding-bottom (uint): extra pixels on the bottom
|
|
- padding-left (uint): extra pixels on the left side
|
|
- padding-right (uint): extra pixels on the right side
|
|
- stride-align0 (uint): stride align requirements for plane 0
|
|
- stride-align1 (uint): stride align requirements for plane 1
|
|
- stride-align2 (uint): stride align requirements for plane 2
|
|
- stride-align3 (uint): stride align requirements for plane 3
|
|
The padding and stride-align fields have the same semantic as #GstVideoMeta.alignment
|
|
and so represent the paddings and stride-align requested on produced video buffers.
|
|
|
|
Since 1.24 it can be serialized using gst_meta_serialize() and

gst_meta_deserialize().</doc>

|
<doc xml:space="preserve" filename="../subprojects/gst-plugins-base/gst-libs/gst/video/videooverlay.c">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" filename="../subprojects/gst-plugins-base/gst-libs/gst/video/video-overlay-composition.c">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>

the structures with the various video-specific information you need to access

the pixels of the video buffer. You can then use accessor macros such as

GST_VIDEO_FRAME_COMP_DATA(), GST_VIDEO_FRAME_PLANE_DATA(),

GST_VIDEO_FRAME_COMP_STRIDE(), GST_VIDEO_FRAME_PLANE_STRIDE() etc.

The purpose of this function is to make it easy for you to get to the video
|
|
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>
