Move the handling of chat events into the shared library so it can be
used by multiple recording formats.
The anonymization of names is based on the external user id, if
available, so users have a consistent name through the meeting. Note
that no effort is made to edit chat messages - if someone is mentioned
by name in a chat message, that will still be visible.
Default settings for anonymization can be controlled in
bigbluebutton.yml, and per-meeting overrides can be done using meta
parameters on the create call.
Generate a external_videos.json file at the recordings with an array of
played external videos url and timestamp.
This file will be published along with the other presentation format files
and can be used to display at the playback.
Generate a poll JSON file at the recordings with an array of published
polling data:
- type;
- question;
- answers;
- number of responders; and
- number of respondents
This file will be published along with the other presentation format files
and can be used to display the poll results at the playback.
Collects the shared notes' HTML raw data and publishes it along with the other
recording files. The playback will fetch for this file and include an option to
display it's content over the chat.
Write a tool that generates the poll svg images directly from the
BBB poll description. This avoids the issues with special characters
in the gnuplot labels, and gives us a lot more flexibility in how
the polls are formatted and styled.
It was previously trying to get the presentation name from the wrong variable,
which resulted in a nil value (which was treated as a blank string in
filenames). This caused the poll images to not be inside the presentation
subdirectories, and the poll image references in the svg contained a `//`
path, which would break the recording if it was uploaded to e.g. AWS S3.
In some cases, we get DRAW_END events for pencil shapes from the
html5 client that have no dataPoints. The only thing we can really
do here is detect the issue and ignore the shape.
In some cases, this may result in the shape's intermediate drawing
updates being shown, but it'll disappear when the end event happens.
- some conflicts have been fixed.

Parking as need to work on something else.
This improves the quality of portrait documents, before they were
1200px when landscape documents got 1600px.
Switching to scaling to a square means that we can use the "-scale-to"
option on pdftocaio, which means that it generates images directly
at the desired size. This can save quite a bit of time (and memory)
if a document was uploaded with extremely large page size.
Some old recordings might have invalid or legacy encoding stuff
in the text files. To allow processing to continue, just re-encode int
UTF-8 with the invalid option set to replace, to remove the invalid
characters.
In BBB 2.0, the cursor positions are given relative to the page
size (like annotation positions). Since the recording cursors
aren't actually drawn in the page like annotations, it's more
convenient to have them relative to the visible area (viewbox),
so do that conversion.
While I'm in here - since we switched to new incompatible scripts
for BBB 2.0 anyways - remove an extra factor in the cursor positions
in cursor.xml, and just use a simple ratio of width/height instead.
This is just a bundle of a few things I've been fixing up in the past
while.
= Workaround for BBB 1.1 beta deskshare timestamp bug
This is unlikely to be used, but I have the code for it, might as
well merge it in.
= Rework video tiling code for ffmpeg
Render video using the 'hstack' and 'vstack' filters rather than the
'overlay' filter. This is somewhat faster, particularly with lots of
videos.
= Etc.
- Remove usage of the streamio-ffmpeg gem.
The video rendering code has some stuff to directly read 'ffprobe'
output, so re-use that instead of this gem (which is kind of old and
has issues with newer ffmpeg versions).
- Don't hardcode the deskshare video area size, pull it from the
properties file
- Remove some code that worked around missing video end events.
In some cases this could cause flickering or strange video issues.
It's no longer strictly needed, the new tiling code doesn't break if
the seekpoint is after the end of the video.
The new shapes code, required for handling smooth shape updates & multi-user
whiteboard in the 2.0 BigBlueButton, hits a bug in old recordings where
the pencil tool incorrectly used "line" in its shape names, meaning that
there could be both a pencil mark and a line with the same shape name.
The old recording code didn't rely on the shape name to match shapes, since
there was no chance of concurrent shapes. As this is an incompatible playback
change, we need to make a new playback directory for the updated files.
The old code was very difficult to follow, and I couldn't figure out
a good way to retrofit the BigBlueButton 2.0 undo by shape id and clear
by user id into it - so I rewrote the entire thing instead.
It now generates the shapes.svg, panzooms.xml and cursor.xml all at the
same time during a single pass through the event.xml file. The result
is compatible with the existing recording javascript (at least once a few
minor issues in writing.js were fixed by earlier commits).
In BBB 0.81, the slide number was base 0, while the shape page number was
base 1. We already have a conditional for checking 0.9+; use that to
add a workaround for old BBB recordings.
