Changed the names of tldraw record events to differentiate from before.
Publish tldraw.json file with all shape information during the meeting to be used in playback.
Adapted cursor.xml and panzoom.xml to store tldraw data.
Publish slides svgs to be used by playback's tldraw component (otherwise we have different image sizes in pngs and thus messing the coordinates).
Retro-compatible with old recordings.
Uses archived raw files directly instead of copying them over.
Specifies absolute paths in XPATH expressions for faster query speeds
Linting changes:
Removes useless assignments to ext, metadata_with_playback variables
Use frozen string literals
Use YAML safe load and JSON parse over load
Rescue StandardError instead of Exception
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.
- some conflicts have been fixed.
The following needs working on:

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.
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.
This is a demo. Some issues:
- When sharing desktop, cursor is still relative to slides, and not to deskshare video;
- Need to show whiteboard canvas on top of deskshare video as well;
- Need more testing (audio/video sync, playback perfomance, multiple presenters and multiple deskshare events).
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.
