>Subject: [PATCH] Bug 8377 [ENH] Show HTML5 video/ audio for media files in OPAC and staff client
>Content-Type: text/plain; charset="utf-8"
>
>This enhancement uses information from MARC field 856 to generate the appropriate HTML5 code to embed am media player for the file(s) in a tab in the OPAC and staff client detail view. This patch supports the HTML5 <audio> and <video> element. Additionally it gives basic support for the <track> element. This element is not supported very well by recent browsers. Please consider the patch working when you get working video or audio.
>
>Changes since last version:
>- failed QA: removed default view for media tab, changed tab name to "Play audio" resp. "Play video".
>- put most of the code in separate module and access it from OPAC and staff client now, so the feature works in both
>- had to change sysprefs: HTML5MediaEnabled can be 'none', 'opac', 'staff' or 'both'
>
>* Removed default entry for mp3 again to not imply it is widely supported or going to be by free software browsers.
>
>If you tested this before, you need to delete the old syspref entries from your database. There is an attachment to do this, use exactly like upgradedatabase.pl.
>
>Test plan
>
>- Import attached test data. [I chose media typ 'bk' because it's probably present on most systems. It's not appropriate for the data but that doesn't matter.]
>- Rebuild zebra -b -z
>- Go to Administration->System preferences->enhanced content->HTML5 Media and set HTML5MediaEnabled to an appropriate setting, save preferences.
>- Search the OPAC or staff client for 'bug 8377'
>- Get 4 results
>- Open detail pages for results. Observe working video (1-3) or audio (4) player on detail page.
>
>Squashed both patches together
