Ssl bug in playback prevents playback

[Marc Schipperheyn]

If you access the playback module in ssl, it will load supporting assets such as svg assets over http in stead of https.

The 0.81 subsequently works without displaying slides. The 0.9 version fails entirely.

Could someone look at this please?

Cheers

Marc,

We changed the recording scripts to write https: in the metadata xml

What's happening is the player playback.html is serving http:.   Need to look as the .js in player directory and modify any http to https.

As you can see in the attachment,  chrome will not served mixed content for the SVG.  cant remember if any other cases exist.

Should be straight forward fix.

regards,

Stephen

here is the line in recordings to get https in metadata

The player

https://github.com/bigbluebutton/bigbluebutton/blob/master/record-and-playback/presentation/playback/presentation/0.9.0/playback.html

This line is writing.js lib

https://github.com/bigbluebutton/bigbluebutton/blob/master/record-and-playback/presentation/playback/presentation/0.9.0/lib/writing.js#L481

Give it a try it should work. or a least get you further in the debug process.

We adapted it so our recordings are played directly from S3.

regards,

I've tried changing this line in writing.js the test-install server to
say
   var url = "/presentation/" + MEETINGID;
(I.e. completely remove the protocol and host) and it looks like it's
working, see:
https://test-install.blindsidenetworks.com/playback/presentation/0.9.0/playback.html?meetingId=6e35e3b2778883f5db637d7a5dba0a427f692e91-1444551609052
This change is pretty simple and won't break non-https recordings, so
I'll put it into the 1.0-beta build.

There should be an equivalent change I can make to the 0.81 playback
scripts so they'll work; I'll look into it.

It already looks like that on my version:

var url = "/presentation/" + MEETINGID;

The offending reference is in

https://github.com/bigbluebutton/bigbluebutton/blob/8f789974a759a4f32ebc7039b25a2fc0d62fc61d/record-and-playback/core/scripts/bigbluebutton.yml

But I'm not sure in what config file it ends up

[Marc Schipperheyn]

Ok, yeah found it. The http:// reference is in the file "writing.js" at line 474
