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.)
This fixes loading the shapes svg, and the events and cursor xml files
on servers configured with https support. (Otherwise they'll be loaded
off http:// and trigger mixed-content errors).
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.
There are many codes other than '404' which indicate that the media
file is not present or otherwise unusable. Instead of checking for
a particular failure mode, check for explicit success.
I ran into this on a server that had directory listing disabled, and
returned a 403 (access denied) error on non-existant files.
We can only get here if all of the files for the presentation are
*completely* missing. One thing that can cause this is if the
presentation filename starts with a '.' character - the presentation
files aren't correctly archived then.
Firefox has a bug where it can't seek in the audio-only webm files with
no cues, and it seems like they have no intention of fixing this...
Serve up the ogg files first for them.
Adding cues to audio-only webm files is *hard*, there are no standard
tools that support doing this cleanly.
This shouldn't normally be hit... but if it ever is, the processing will
fail with an error, since the Logger class doesn't have a method named
'warning'.
We now use ghostscript to output pngs directly from the original pdf,
rather than using convert on the split pages. This should make corrupt
or strange pdfs less likely to cause issues.
As well, if a pdf page conversion fails (for any reason, including that
the original pdf is missing...) it will be logged, and a blank page
generated, and processing will continue.
