The proper behavior should be that...
if there is a "start poster" then it must be displayed while any
pre-loading takes place, if there is no pre-loading or auto-play then it
must remain displayed until the user press play/pause/stop.
if there is a "start poster" then it must be removed if the user press
play/pause/stop or pre-loading has progressed far enough for autoplay to
I'd also like to add that...
If the user pauses the video during play then a "paused poster" must not
be shown as the user most likely intends to study the paused frame of
the video, if there is a "paused poster" then it must be toggleable
between "paused poster" and frame by the user as they please, a small
symbol or control may be shown during the paused frame to indicate there
is a "paused poster" available.
And I'd also like to add that...
If there is a "end poster" then it must be displayed when the user stop
the video, or if the last frame of the video is reached then the "end
poster" but be shown.
Finally I'd like to add that...
There may be one or more posters, the start/pause/end posters may be the
exact same poster or different posters.
The 3 different types of posters must be scriptable to allow rotation
between multiple different posters.
Does this sound like something that would satisfy both developers and
users, without annoying either?
Personally I do not see much point in a "paused poster" but I guess if
it's scriptable it could act as a info card or maybe repeat the chapter
title or something like that!
Does posters support hotzones at all? To allow clickable
items/links/symbols (urls?). Just curious!
