One of the first comments on the new UNIX history video, from a non-unix person with many years experience in video, was:
I'm planning to produce another video on this topic sometime later this year, with a title like "The Dark History of UNIX" where we show the history of the legal and trademark battles that besieged and hurt UNIX in the 2000 - 2010 time frame.
It's not a favorite topic of mine (the years of legal battles), but it might make an informative video and there are "no shortages" of "history videos" that do not cover the years of self-defeating legal wrangling.

Xv(3X) Xv(3X)
Name
Xv - X Window System video extension
Description
The Xv extension provides support for video adaptors attached to an X display. It takes the approach that a display may have one or more
video adaptors, each of which has one or more ports through which independent video streams pass.
An adaptor may be able to display video in a drawable, capture video from a drawable, or both. It translates between video encoding (NTSC,
PAL, SECAM, etc...) and drawable format (depth and visual-id pair). An adaptor may support multiple video encodings and/or multiple draw-
able formats.
Clients use Xv(3X) to gain access and manage sharing of a display's video resources. Typically, a client will use XvQueryExtension(3X) to
determine the status of the extension, XvQueryAdaptors(3X) to get a description of what video adaptors exist, and XvQueryEncodings(3X) to
get a description of what video encodings an adaptor supports.
Once a client has determined what video resources are available, it is free to put video into a drawable or get video from a drawable,
according the capabilities supported. Clients can select to receive events when video activity changes in a drawable and when port
attributes have changed.
Summary of Library Functions
The following is a summary of Xv library functions:
XvGetPortAttribute(3X) - return current port attribute value
XvGetStill(3X) - capture a single frame of video from a drawable
XvGetVideo(3X) - capture video from a drawable
XvGrabPort(3X) - lock port for exclusive use by client
XvPortNotify(3X) - event generated when port attributes change
XvPutStill(3X) - write a single frame of video to a drawable
XvPutVideo(3X) - write video into a drawable
XvQueryAdaptors(3X) - return adaptor information for a screen
XvQueryBestSize(3X) - determine the optimum drawable region size
XvQueryEncodings(3X) - return list of encodings for an adaptor
XvQueryExtension(3X) - return version and revision of extension
XvSelectPortNotify(3X) - enable or disable XvPortNotify events
XvSelectVideoNotify(3X) - enable or disable XvVideoNotify events
XvSetPortAttribute(3X) - set an attribute for a port
XvStopVideo(3X) - stop active video
XvUngrabPort(3X) - release a grabbed port
XvVideoNotify(3X) - event generated for video processing
Each of these functions is described in its own Xv man page.
