Unable to see transcripts for minutes before the player was launched #60

If you join the meeting late, the player only shows you the transcripts from that point onwards. The transcripts for the previous minutes are not available. We would like to see the transcript for minutes that have elapsed before joining the meeting.

Please document the platform e.g. Chrome on Windows?

Also if you can seek backwards in time, the captions should appear. Please can you check this?

Other comments This might be difficult/impractical to implement using the current embedded caption; we're currently at the whim of the video support by the browser and the server. i.e. it might need a whole different broadcast infrastructure for the captions etc.

The Kaltura streaming server is free to discard early portions of the stream,especially if the stream is not being recorded. We will need to confirm how much of the old content it is prepared to buffer. The player uses the browser video tag to decode the mp4 stream. If the earlier captions are not availble in the browser object then the player cannot display them. So as a todo: Check to see if an y earlier captions are in the video element, and if they fail to be added to the side transcript for some reason..

Also I think this feature probably belongs on the player repo not CT Cast. https://github.com/classtranscribe/liveplayer/issues

Will attempt to reproduce it during Testing on Tuesday. Is this related to turning the captions on and off?
