--- Comment #20 from MBB <mbbthebest at yahoo.com> ---
It is a question that sometimes pops up at the ask.libreoffice.org and other
fora.
 A search on Youtube shows this to be a very popular use, with many tutorial
videos on how to record presentations. 
 An issue to simplify the process would be a way to start and stop the
recording software at the same time as the presentation plays. 
 Using a third-party program for side features is not new for LO as it also
uses the Thunderbird address book for mailing list letters. 


 A multiplatform Opensource (GPL2) program named OBS Studio has become the
standard for recording, and supports enhancement by plug-ins. Originally
intended for webcam recording/streaming it also allows recording of the desktop
and other input streams. 

 I think it could be a good idea to use its wide capacity for recording to
export Impress presentations to video, preferably by projecting directly to
OSB. 
 For this it would need either by a plugin for LibreOffice, for OBS or for
both. 

 It could be a plugin/extension in LO Impress that calls OSB and tells it to
start/stop recording. (With maybe a template for OBS to get window name and
video size parameters?)

 Or an OBSstudio plugin where you select the presentation and then runs
LibreOffice from the command line (to a virtual screen for recording?)


 I am not a programmer, but  I imagine the the GUI/program would look a bit
like this:
 ====
 Select video size [get from Presentation (default checkbox) / Set manual 

 Set export directory
  - Same as presentation
  - OBS default
  - set manual

 Split each projection into separate video [yes/no checkbox]
 Offer presentation options
        audio yes/no?
        comments yes/no?

Record webcam/audio for presentation (in a different stream)

Select Record speed (CPU use): Fastest/RealTime/Background

 > StartRecord + StartPlayImpress
