+ Preface
+ -------
+
+ The following is an outline for an X video extension protocol. It
+ is preliminary and subject to change. My goal in writing this was
+ to fix some the shortcomings of existing overly simplistic
+ extensions while avoiding pitfalls in an overly complex extension.
+
+ Your feedback is desired, and since the major design directions
+ have been stable for some time, feel free to hammer on the details
+ of the protocol.
+
+ When you receive a revision of the document, refer to the changes
+ and issues sections to guide your review and analysis.
+
+
+ Acknowledgements
+ ---------------
+
+ The following people have made major contributions to the design of
+ the Xv protocol:
+
+ Branko Gerovac (DEC/Corporate Research)
+ Russ Sasnett (GTE/Project Athena)
+ Ralph Swick (DEC/Project Athena)
+
+ Many ideas and approaches in Xv were the product of discussions
+ with several groups, including
+
+ Project Athena's Visual Computing Group
+ The MIT X Consortium
+ The MIT Media Lab's Interactive Cinema Group
+
+
+ \f
+ Changes
+ -------
+
+ From version 1.3 to 2.0
+
+ -- Changed SetPortControl and GetPortControl to GetPortAttribute
+ and SetPortAttribute.
+
+ -- Changed QueryBestSize
+
+ -- Simplified SelectVideoNotify and SelectPortNotify requests.
+
+ -- Changed the way SetPortControl and GetPortControl works.
+
+ -- Added a QueryExtension request to return the version and
+ revision information of the extension.
+
+ -- Changed the name of the QueryVideo request to QueryAdaptors;
+ Removed the list of encodings from QueryVideo and added a
+ QueryEncodings request.
+
+ -- Added a PortNotify event that notifies interested clients that
+ a port control has been changed.
+
+ -- Added SelectPortNotify request to select for PortNotify events.
+
+ -- The XvInterruped reason has been replaced by two new reasons:
+ one for when video is preempted by another video request and
+ one for when video is terminated because of hard transmission
+ or reception errors.
+
+ -- Changed the wording of the QueryBestSize request. Added issue
+ about whether or not returned sizes should maintain the
+ requested aspect ratio.
+
+\f
+
+ Introduction
+ ------------
+
+ Video technology is moving very quickly. Standards for processing
+ high resolution video are currently a hot topic of discussion
+ internationally, and it will soon be possible to process video
+ entirely within the digital domain. The Xv extension, however,
+ does not attempt to address issues of digital video. Its purpose
+ is to provide a mechanism for support of current and near term
+ interactive video technology.
+
+ It is somewhat ironic that Xv contains nothing particularly
+ innovative. It takes a minimalistic approach, and without a doubt
+ it could have been defined years ago, and with several revisions.
+ So, the life expectancy of Xv is not long. Nevertheless, it may
+ undergo further revision and experimentation that will help our
+ progress towards digital video systems.
+
+ One premise of the Xv extension is that the X server is not alone.
+ A separate video server is often used to manage other aspects of
+ video processing, though the partition between what the X server
+ does and what a video server does is a matter of great debate.
+
+
+ Model
+ -----
+
+ This extension models video monitor capabilities in the X Window
+ System. Some advanced monitors support the simultaneous display
+ of multiple video signals (into separate windows), and that is
+ prepresented here through the ability to display video from
+ multiple video input adaptors into X drawables.
+
+ Some monitors support multiple video encodings (mostly for
+ internationalization purposes) either through switches or
+ automatic detection, thus each video adaptor specifies the set of
+ encodings it supports.
+
+ The requests to display video from an adaptor into a drawable are
+ modeled after the core PutImage request, though extended to
+ support scaling and source clipping.
+
+ Video output is also supported and is symmetric with the video
+ input function, though fewer GC components are used.
+
+
+ Mechanism
+ ---------
+
+ The Xv extension does the following:
+
+ -- lists available video adaptors
+ -- identifies the number of ports each adaptor supports
+ -- describes what drawable formats each adaptor supports
+ -- describes what video encodings each adaptor supports
+ -- displays video from a port to a drawable
+ -- captures video from a drawable to a port
+ -- grabs and ungrabs ports
+ -- sets and gets port attributes
+ -- delivers event notification
+
+\f
+
+ Adaptors
+ --------
+
+ A display may have multiple video input and output adaptors. An
+ adaptor may support multiple simultaneously active ports, and in
+ some cases the number of ports has no fixed limit.
+
+ An input port receives encoded video data and converts it to a
+ stream of data used to update a drawable. An output port samples
+ data from a drawable and produces a stream of encoded video data.
+
+ The ADAPTORINFO structure is used to describe a video adaptor.
+
+ ADAPTORINFO:
+ [base-id: PORT
+ num-ports: CARD16
+ type: SETofADAPTORTYPE
+ formats: LISTofFORMAT
+ name: STRING]
+
+ ADAPTORTYPE: {Input, Output}
+
+ FORMAT:
+ [depth: CARD8
+ visual: VISUALID]
+
+ The base-id field specifies the XID of the first port of the
+ adaptor. The `num-ports' field specifies how many ports the
+ adaptor supports. The ports of the adaptor have XIDs in the range
+ [base-id..base-id + num-ports - 1]
+
+ The type attribute determines if the adaptor can process video
+ input, output, or input and output. The if the adaptor can
+ process input then Input is asserted, if the adaptor can process
+ output then Output is asserted.
+
+ The drawable depths and visual types supported by the adaptor are
+ listed in `formats'. Note: that when video is being processed for
+ pixmaps the visual format is taken to be the visual of the first
+ pair that matches the depth of the pixmap.
+
+ The name field contains an a vendor specific string that
+ identifies the adaptor.
+
+ It should be noted that the existence of separate adaptors doesn't
+ necessarily imply that simultaneous operation is supported.
+
+\f
+
+ Errors
+ ------
+
+ Port
+
+ A Port error is returned if any request names a PORT that does not
+ exist.
+
+
+ Encoding
+
+ An Encoding error is returned if any request names an ENCODINGID
+ that does not exist.
+
+
+\f
+
+ Query Requests
+ -------------------
+
+ QueryExtension
+ ==>
+ version: CARD16
+ revision: CARD16
+
+ The QueryExtension request returns the extension version and
+ revision numbers.
+
+
+ QueryAdaptors
+ win: WINDOW
+ ==>
+ adaptors: LISTofADAPTORINFO
+
+ The QueryAdaptors request returns the video adaptor information for
+ the screen of the specified window.
+
+ Errors: {Window}
+
+
+ QueryEncodings
+ port: PORT
+ ==>
+ encodings: LISTofENCODINGINFO
+
+ The QueryEncodings request returns the list of encodings supported
+ by the port adaptor. Use the SetPortAttribute request to set
+ which encoding a port is to process. The ENCODINGINFO record
+ describes an encoding:
+
+ ENCODINGINFO:
+ [encoding: ENCODINGID
+ name: STRING
+ width, height: CARD16
+ rate: FRACTION]
+
+ The `encoding' field identifies an encoding supported by a port.
+ Its value is unique for a screen. Width and height specify the
+ size of the video image and rate specifies the rate at which
+ fields of image information are encoded.
+
+ An encoding is identified by a string that names the encoding.
+ Encoding naming conventions need to be established (i.e.,
+ something along the lines of font naming, but simpler)
+
+ FRACTION
+ [numerator, denominator: INT32]
+
+ The FRACTION structure is used to specify a fractional number.
+
+ Errors: {Port}
+
+\f
+
+ Put Video Requests
+ ------------------
+
+ PutVideo
+ port: PORT
+ drawable: DRAWABLE
+ gc: GCONTEXT
+ vid-x, vid-y: INT16
+ vid-w, vid-h: CARD16
+ drw-x, drw-y: INT16
+ drw-w, drw-h: CARD16
+
+ The PutVideo request writes video into a drawable. The position
+ and size of the source rectangle is specified by vid-x, vid-y,
+ vid-w, and vid-h. The position and size of the destination
+ rectangle is specified by drw-x, drw-y, drw-w, drw-h.
+
+ Video data is clipped to the bounds of the video encoding, scaled
+ to the requested drawable region size (or the closest size
+ supported), and clipped to the bounds of the drawable.
+
+ If video is successfully initiated, a VideoNotify event with
+ detail Started is generated for the drawable. If the port is
+ already in use, its video is preempted, and if the new drawable is
+ different than the old, a VideoNotify event with detail Preempted
+ is generated for the old drawable. If the port is grabbed by
+ another client, this request is ignored, and a VideoNotify event
+ with detail Busy is generated for the drawable. If the port is
+ not receiving a valid video signal or if the video signal is
+ interrupted while video is active a VideoNotify event with detail
+ HardError is generated for the drawable.
+
+ GC components: subwindow-mode, clip-x-origin, clip-y-origin, clip-mask.
+
+ Errors: {Match, Value, GContext, Port, Alloc}
+
+
+ PutStill
+ port: PORT

+ vid-x, vid-y: INT16
+ vid-w, vid-h: CARD16
+ drw-x, drw-y: INT16
+ drw-w, drw-h: CARD16
+
+ The PutStill request writes a single frame of video into a
+ drawable. The position and size of the source rectangle is
+ specified by vid-x, vid-y, vid-w, and vid-h. The position and
+ size of the destination rectangle is specified by drw-x, drw-y,
+ drw-w, drw-h.
+
+ Video data is clipped to the bounds of the video encoding, scaled
+ to the requested drawable region size (or the closest size
+ supported) and clipped to the bounds of the drawable.
+
+ If the port is grabbed by another client, this request is ignored,
+ and a VideoNotify event with detail Busy is generated for the
+ drawable. If the port is not receiving a valid video signal a
+ VideoNotify event with detail HardError is generated for the
+ drawable.
+
+ GC components: subwindow-mode, clip-x-origin, clip-y-origin, clip-mask.

+ drw-w, drw-h: CARD16
+
+ The GetVideo request outputs video from a drawable. The position
+ and size of the destination rectangle is specified by vid-x,
+ vid-y, vid-w, and vid-h. The position and size of the source
+ rectangle is specified by drw-x, drw-y, drw-w, and drw-h.
+
+ Drawable data is clipped to the bounds of the drawable, scaled to
+ the requested video region size (or the closest size supported)
+ and clipped to the bounds of the video encoding. The contents of
+ any region not updated with drawable data is undefined.
+
+ If video is successfully initiated, a VideoNotify event with

+
+ Grab Requests
+ -------------
+
+ GrabPort
+ port: PORT
+ timestamp: {TIMESTAMP, CurrentTime}
+ ==>
+ status: {Success, AlreadyGrabbed, InvalidTime}
+
+ The GrabPort request grabs a port. While a port is grabbed, only
+ video requests from the grabbing client are permitted.
+
+ If timestamp specifies a time older than the current port time, a
+ status of InvalidTime is returned. If the port is already grabbed
+ by another client, a status of AlreadyGrabbed is returned.
+ Otherwise a status of Success is returned. The port time is
+ updated when the following requests are processed: GrabPort,
+ UngrabPort, PutVideo, PutStill, GetVideo, GetStill
+
+ If the port is actively processing video for another client, the
+ video is preempted, and an VideoNotify event with detail Preempted
+ is generated for its drawable.
+
+ Errors: {Port}
+
+
+ UngrabPort
+ port: PORT
+ timestamp: {TIMESTAMP, CurrentTime}
+
+ The UngrabPort request ungrabs a port. If timestamp specifies a
+ time before the last connection request time of this port, the
+ request is ignored.
+
+ Errors: {Port}
+
+\f
+
+ Other Requests
+ --------------
+
+ StopVideo
+ port: PORT
+ drawable: DRAWABLE
+
+ The StopVideo request stops active video for the specified port
+ and drawable. If the port isn't processing video, or if it is
+ processing video in a different drawable, the request is ignored.
+ When video is stopped a VideoNotify event with detail Stopped is
+ generated for the associated drawable.
+
+ Errors: {Drawable, Port}
+
+
+ SelectVideoNotify
+ drawable: DRAWABLE
+ onoff: BOOL
+
+ The SelectVideoNotify request enables or disables VideoNotify
+ event delivery to the requesting client. VideoNotify events are
+ generated when video starts and stops.
+
+ Errors: {Drawable}
+
+
+ SelectPortNotify
+ port: PORT
+ onoff: BOOL
+
+ The SelectPortNotify request enables or disables PortNotify event
+ delivery to the requesting client. PortNotify events are
+ generated when port attributes are changed using SetPortAttribute.
+
+ Errors: {Port}
+
+
+ QueryBestSize
+ port: PORT
+ motion: BOOL
+ vid-w, vid-h: CARD16
+ drw-w, drw-h: CARD16
+ ==>
+ actual-width, actual-height: CARD16
+
+ The QueryBestSize request returns, for the given source size and
+ desired destination size, the closest destination size that the
+ port adaptor supports. The returned size will be equal
+ or smaller than the requested size if one is supported. If motion
+ is True then the requested size is intended for use with full
+ motion video. If motion is False, the requested size is intended
+ for use with stills only.
+
+ The retuned size is also chosen to maintain the requested aspect ratio
+ if possible.
+
+ Errors: {Port}
+
+\f
+
+ SetPortAttribute
+ port: PORT
+ attribute: ATOM
+ value: INT32
+
+ The SetPortAttribute request sets the value of a port attribute.
+ The port attribute is identified by the attribute atom. The
+ following strings are guaranteed to generate valid atoms using the
+ InternAtom request.
+
+ String Type
+ -----------------------------------------------------------------
+
+ "XV_ENCODING" ENCODINGID
+ "XV_HUE" [-1000..1000]
+ "XV_SATURATION" [-1000..1000]
+ "XV_BRIGHTNESS" [-1000..1000]
+ "XV_CONTRAST" [-1000..1000]
+
+
+ If the given attribute doesn't match an attribute supported by the
+ port adaptor a Match error is generated. The supplied encoding
+ must be one of the encodings listed for the adaptor, otherwise an
+ Encoding error is generated.
+
+ If the adaptor doesn't support the exact hue, saturation,
+ brightness, and contrast levels supplied, the closest levels
+ supported are assumed. The GetPortAttribute request can be used
+ to query the resulting levels.
+
+ When a SetPortAttribute request is processed a PortNotify event is
+ generated for all clients that have requested port change
+ notification using SelectPortNotify.
+
+ Errors: {Port, Match, Value}
+
+
+ GetPortAttribute
+ port: PORT
+ attribute: ATOM
+ ==>
+ value: INT32
+
+
+ The GetPortAttribute request returns the current value of the
+ attribute identified by the given atom. If the given atom
+ doesn't match an attribute supported by the adaptor a Match
+ error is generated.
+
+ Errors: {Port, Match}

+
+ Events
+ ------
+
+ VideoNotify
+ drawable: DRAWABLE
+ port: PORT
+ reason: REASON
+ time: TIMESTAMP
+
+ REASON: {Started, Still, Stopped, Busy, Preempted, HardError}
+
+ A VideoNotify event is generated when video activity is started,
+ stopped, or unable to proceed in a drawable.
+
+ A Started reason is generated when video starts in a drawable.
+
+ A Stopped reason is generated when video is stopped in a
+ drawable upon request.
+
+ A Busy reason is generated when a put or get request cannot
+ proceed because the port is grabbed by another client.
+
+ A Preempted reason is generated when video is stopped by a
+ conflicting request.
+
+ A HardError reason is generated when the video port cannot
+ initiate or continue processing a video request because of an
+ underlying transmission or reception error.
+
+
+ PortNotify
+ port: PORT
+ attribute: ATOM
+ value: INT32
+ time: TIMESTAMP
+
+ The PortNotify event is generated when a SetPortAttribute request
+ is processed. The event is delivered to all clients that have
+ performed a SelectPortNotify request for the port. The event
+ contains the atom identifying the attribute that changed, and the
+ new value of that attribute.
