Right now the captions are only rendered if there's a video present. If
the meeting doesn't have a video (webcam or desktop sharing), we'll need
to just make up a blank one.
Custom poll answers were previously printed into the gnuplot control
file directly, between double-quotes. As a result, if a poll answer
contains a double-quote, it could cause a syntax error in the gnuplot
script, or worse.
Gnuplot accepts standard C-style double-quoted string escapes, so I can
just use ruby's "inspect" method to generate a safetly escaped string.
Note that within the string, % still has to be escaped separately
(doubled) to avoid issues with the string formatting. As well, I have
disabled "enhanced" mode which allows using special characters for
formatting commands.

These were commented out, apparently by accident, when the metadata code
was being refactored. The effect was that the $meeting_end variable was
treated as if it had a value of zero, meaning that the last slide had a
start time of some positive number and an end time of zero. As a result,
it was never shown (and didn't get any shapes either).
Fixes#3021
This allows configuring a server to use https without having to edit
any ruby files directly.
(Ideally, the metadata files wouldn't include the server name/protocol
at all; that should be set dynamically by bbb-web, but this is what we
have for now.)
There were a couple of problems:
* A division by 0 when calculating the percentages
* Positioning of the number of results counter was incorrect
Fixes#2739
Note that this requires a new dependency be added to the
"bbb-playback-presentation" format; the "gnuplot" package is now
required (it's used to actually generate the chart images)
In 0.9.0, the slide clear events changed from using 1-based page numbers to
using 0-based page numbers.
Add 1 to the page number for recordings generated on a 0.9.0+ server to
fix the issue; at this point it's too late in the release to change the value,
and there's too big of a body of existing recordings out there.
Now the 0.81 presentation playback files are in an appropriate versioned
directory. If desired, the recording metadata can be updated to reference
the versioned files directly, but an nginx redirect has been added so
that unmodified recordings will also work.
This makes it a bit more obvious how the versioning can work going
forwards, and makes it so that we do not need to update the nginx
config each time we have a new version of the playback files.
The 0.81 files remain at the top level of the presentation directory
for compatibility reasons.
This fixes an issue where recordings copied from a 0.81 server might
not play back correctly on a 0.9 server.
This changes the 0.9 recording scripts to use playback support files
from a different subdirectory, 'presentation2', while existing 0.81
recordings continue to use the 'presentation' directory.
If the raw files from an old recording are reprocessed, it will
switch to using the newer playback support files.
This was added because BigBlueButton 0.9 started using 1-based page
numbers in the events.xml file. That change has been reverted, so as
to avoid behaviour changes from 0.81 in places where it's unnecessary.
With the switch to a different clock source in red5, the timestamps
in the events file are no longer real-time, but are rather in
seconds since computer boot.
The timestamp in the meeting id is still realtime, so use that as
the start time. Calculate the end time by adding the meeting length
to the start time.
