[WG: Sakai QA] request for help QAing Lessons for 2.9.3

[Charles Hedrick]

I should note that I just updated audio support as well. It seems silly to do HTML5 for video and not audio.

Audio approach is:

HTML5 if the browser claims to support it for mp3, ogg and wav
Strobe for mp3
fall back to <OBJECT> or [for IE] <EMBED>

That should be tested as well.

For both video and audio, the installation can control which players we try for which mime types.

This code is based entirely on MIME types, since as far as I know, Sakai uses them correctly. If for some reason there's a file that doesn't have any MIME type, <OBJECT> or <EMBED> is the only thing we try.

As a result, grades reported by Lessons were not shown to students, and probably were not included in final grade calculations. The same would be true of any contrib tools that had not been updated to implement the new API. I've fixed that. The code needs testing. Specifically it needs testing for graded comments, student content, and comments on student content, and it needs testing specifically when those items are limited to be accessible to specific groups (to the extent that that restriction is possible -- not all of them are group-aware).

However the problem turned out to be in the implementation of /access/lessonbuilder. In the process I fixed several issues: HTML5 is now used to display MP4, webm and ogg, if the browser supports HTML5 and it claims to support the MIME type for the video. Otherwise I next try the Strobe Flash-based player. Finally I use <OBJECT> or <EMBED>, which leaves it to the browser to find a player.  JWPlayer is no longer supported, for licensing reasons. (And the initially reason for using it no longer applies anyway.) I also fixed an issue that caused Quicktime embedding not to work (for browsers that have a Quicktime player, of course). Testing should include MP4, FLV, Quicktime, and if possible webm, ogg, and random types not explicitly supported. Please try as many different browsers as possible, including portable devices.

If you want support for contrib tools you enable the optional profile in tool/pom.xml. The build has been tested on 2.8. (Trunk has also been tested on 2.8.)
