1. Where could one read (wiki or something) about embedding flash video
player (like jw player) for watching and submitting videos into CDS
Invenio in the way it is done onhttp://cds.cern.ch/?
I guess the answer will depend on which player you want to use. Most
probably the player website is the place to start.
On the CDS Invenio side, embedding the player will simply consist in
including the player code in your BibFormat template/element, and
customize the parameters of the player to link to your video file URL,
retrieved as usual from the MARC of the record. For more information
regarding formatting in CDS Invenio, you can refer to the BibFormat
admin guide:
<http://invenio-demo.cern.ch/help/admin/bibformat-admin-guide>
Having videos in your CDS Invenio installation will assume that you
directly upload web versions of your videos, as there is currently no
support for automatic conversion of uploaded videos. So the videos will
be treated as any other files in CDS, and your formatting template will
take care of showing the videos correctly to your users.
Note the CDS Invenio does not support streaming of videos, but
progressive download only. Still support for the HTTP "content-range"
header will let some players move to any place in the video before it is
fully downloaded (could this be called pseudo-streaming?).
3. And at last a naive question: is there a specific reason (copyright
etc.) for not including jw player and "Demo video submission" into a
standard CDS Invenio distro? I suppose it would be extremely useful.
The player you are referring is open source, but requires some
particular tools to be compiled. The compiled downloadable version can
be freely used on "non-commercial" website, but includes a watermark..
In the end this is does not seem to be a really satisfactory solution to
use by default in an open-source software.
A more adequate sample setup will most probably involve the use of the
HTML5 <video> tag. That is more in line with the philosophy of the CDS
Invenio demo website, which is to provide a feature-full but simple
setup, from which you can start building advanced customizations.
A simple and down-to-earth answer to why there is no default video
submission and templates is simply that no one ever worked on it... As
usual, contributions are welcome!
