-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> - <source-position filename="gst-libs/gst/video/gstvideodecoder.h" - line="342"/> - <virtual-method name="close"> - <source-position filename="gst-libs/gst/video/gstvideodecoder.h" - line="289"/> - <return-value transfer-ownership="none"> - <type name="gboolean" c:type="gboolean"/> - </return-value> - <parameters> - <instance-parameter name="decoder" transfer-ownership="none"> - <type name="VideoDecoder" c:type="GstVideoDecoder*"/> - </instance-parameter> - </parameters> - </virtual-method> - <virtual-method name="decide_allocation"> - <source-position filename="gst-libs/gst/video/gstvideodecoder.h" - line="319"/> - <return-value transfer-ownership="none"> - <type name="gboolean" c:type="gboolean"/> - </return-value> - <parameters> - <instance-parameter name="decoder" transfer-ownership="none"> - <type name="VideoDecoder" c:type="GstVideoDecoder*"/> - </instance-parameter> - <parameter name="query" transfer-ownership="none"> - <type name="Gst.Query" c:type="GstQuery*"/> - </parameter> - </parameters> - </virtual-method> - <virtual-method name="drain"> - <source-position filename="gst-libs/gst/video/gstvideodecoder.h" - line="334"/> - <return-value transfer-ownership="none"> - <type name="Gst.FlowReturn" c:type="GstFlowReturn"/> - </return-value> - <parameters> - <instance-parameter name="decoder" transfer-ownership="none"> - <type name="VideoDecoder" c:type="GstVideoDecoder*"/> - </instance-parameter> - </parameters> - </virtual-method> - <virtual-method name="finish"> - <source-position filename="gst-libs/gst/video/gstvideodecoder.h" - line="306"/> - <return-value transfer-ownership="none"> - <type name="Gst.FlowReturn" c:type="GstFlowReturn"/> - </return-value> - <parameters> - <instance-parameter name="decoder" transfer-ownership="none"> - <type name="VideoDecoder" c:type="GstVideoDecoder*"/> - </instance-parameter> - </parameters> - </virtual-method> - <virtual-method name="flush"> - <source-position filename="gst-libs/gst/video/gstvideodecoder.h" - line="323"/> - <return-value transfer-ownership="none"> - <type name="gboolean" c:type="gboolean"/> - </return-value> - <parameters> - <instance-parameter name="decoder" transfer-ownership="none"> - <type name="VideoDecoder" c:type="GstVideoDecoder*"/> - </instance-parameter> - </parameters> - </virtual-method> - <virtual-method name="getcaps"> - <source-position filename="gst-libs/gst/video/gstvideodecoder.h" - line="331"/> - <return-value transfer-ownership="full"> - <type name="Gst.Caps" c:type="GstCaps*"/> - </return-value> - <parameters> - <instance-parameter name="decoder" transfer-ownership="none"> - <type name="VideoDecoder" c:type="GstVideoDecoder*"/> - </instance-parameter> - <parameter name="filter" transfer-ownership="none"> - <type name="Gst.Caps" c:type="GstCaps*"/> - </parameter> - </parameters> - </virtual-method> - <virtual-method name="handle_frame"> - <source-position filename="gst-libs/gst/video/gstvideodecoder.h" - line="308"/> - <return-value transfer-ownership="none"> - <type name="Gst.FlowReturn" c:type="GstFlowReturn"/> - </return-value> - <parameters> - <instance-parameter name="decoder" transfer-ownership="none"> - <type name="VideoDecoder" c:type="GstVideoDecoder*"/> - </instance-parameter> - <parameter name="frame" transfer-ownership="none"> - <type name="VideoCodecFrame" c:type="GstVideoCodecFrame*"/> - </parameter> - </parameters> - </virtual-method> - <virtual-method name="negotiate" invoker="negotiate"> - <doc xml:space="preserve" - filename="gst-libs/gst/video/gstvideodecoder.c" - line="4230">Negotiate with downstream elements to currently configured #GstVideoCodecState. -Unmark GST_PAD_FLAG_NEED_RECONFIGURE in any case.

-## 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> - <source-position filename="gst-libs/gst/video/gstvideoencoder.h" - line="300"/> - <implements name="Gst.Preset"/> - <virtual-method name="close"> - <source-position filename="gst-libs/gst/video/gstvideoencoder.h" - line="251"/> - <return-value transfer-ownership="none"> - <type name="gboolean" c:type="gboolean"/> - </return-value> - <parameters> - <instance-parameter name="encoder" transfer-ownership="none"> - <type name="VideoEncoder" c:type="GstVideoEncoder*"/> - </instance-parameter> - </parameters> - </virtual-method> - <virtual-method name="decide_allocation"> - <source-position filename="gst-libs/gst/video/gstvideoencoder.h" - line="282"/> - <return-value transfer-ownership="none"> - <type name="gboolean" c:type="gboolean"/> - </return-value> - <parameters> - <instance-parameter name="encoder" transfer-ownership="none"> - <type name="VideoEncoder" c:type="GstVideoEncoder*"/> - </instance-parameter> - <parameter name="query" transfer-ownership="none"> - <type name="Gst.Query" c:type="GstQuery*"/> - </parameter> - </parameters> - </virtual-method> - <virtual-method name="finish"> - <source-position filename="gst-libs/gst/video/gstvideoencoder.h" - line="266"/> - <return-value transfer-ownership="none"> - <type name="Gst.FlowReturn" c:type="GstFlowReturn"/> - </return-value> - <parameters> - <instance-parameter name="encoder" transfer-ownership="none"> - <type name="VideoEncoder" c:type="GstVideoEncoder*"/> - </instance-parameter> - </parameters> - </virtual-method> - <virtual-method name="flush"> - <source-position filename="gst-libs/gst/video/gstvideoencoder.h" - line="286"/> - <return-value transfer-ownership="none"> - <type name="gboolean" c:type="gboolean"/> - </return-value> - <parameters> - <instance-parameter name="encoder" transfer-ownership="none"> - <type name="VideoEncoder" c:type="GstVideoEncoder*"/> - </instance-parameter> - </parameters> - </virtual-method> - <virtual-method name="getcaps"> - <source-position filename="gst-libs/gst/video/gstvideoencoder.h" - line="271"/> - <return-value transfer-ownership="full"> - <type name="Gst.Caps" c:type="GstCaps*"/> - </return-value> - <parameters> - <instance-parameter name="enc" transfer-ownership="none"> - <type name="VideoEncoder" c:type="GstVideoEncoder*"/> - </instance-parameter> - <parameter name="filter" transfer-ownership="none"> - <type name="Gst.Caps" c:type="GstCaps*"/> - </parameter> - </parameters> - </virtual-method> - <virtual-method name="handle_frame"> - <source-position filename="gst-libs/gst/video/gstvideoencoder.h" - line="260"/> - <return-value transfer-ownership="none"> - <type name="Gst.FlowReturn" c:type="GstFlowReturn"/> - </return-value> - <parameters> - <instance-parameter name="encoder" transfer-ownership="none"> - <type name="VideoEncoder" c:type="GstVideoEncoder*"/> - </instance-parameter> - <parameter name="frame" transfer-ownership="none"> - <type name="VideoCodecFrame" c:type="GstVideoCodecFrame*"/> - </parameter> - </parameters> - </virtual-method> - <virtual-method name="negotiate" invoker="negotiate"> - <doc xml:space="preserve" - filename="gst-libs/gst/video/gstvideoencoder.c" - line="1992">Negotiate with downstream elements to currently configured #GstVideoCodecState. -Unmark GST_PAD_FLAG_NEED_RECONFIGURE in any case.

glib:type-struct="VideoOverlayInterface"> - <doc xml:space="preserve" - filename="gst-libs/gst/video/videooverlay.c" - line="20">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). - -## GstVideoOverlay and Gtk+ - -|[ -#include &lt;gst/video/videooverlay.h&gt;
