Re: [Dspace-tech] Streaming video assets from DSpace
Hi Jonathan, For what it's worth we've had pretty good luck at the Ohio Digital Resource Commons with Flash Video (.FLV) saved in progressive download format. Right now we are in the process of converting about 2,000 RealMedia (.RM) files, each more than an hour long. We embedded a simple Flash player (.SWF) in the DSpace XMLUI, and pass it the location of the video file so it plays automatically on the 'View Item' page. The video is also available for download in the 'Files in this Item' section of the page. All of our currently available video is behind Films for the Humanities & Sciences copyright, but if you're interested send me a PM and I can let you take a closer look.

[Dspace-tech] Streaming video assets from DSpace
Hello, At the University of Manitoba, we're still running version 1.3.2 and I've been tasked to see if DSpace can play video files straight from the "View/Open" link, so no apparent downloading. The file formats we're interested in are mostly MPEG-2.

Re: [Dspace-tech] streaming video?
Hi, Symlink DSpace project is stopped now. ad to Shane Beers reply -- it would be nice to have everything in central repository. But DSpace doesn't support many features that is needed for downloading big video files - all the things behind such as load balancing, data flow optimalization etc. (it is usual that the servers providing video files are overloaded from time to time, especially when students download captured lessons at the end of the term before exams :-)). That's why we have used the symbolic linking - all the things for optimizing doesn't depend on anything in DSpace. However I can't say "there's no better way how to solve it". The symlinking seemed to be the most elegant way at that time. That's all I would like to add :-) Vlastik On Sun, 25 Nov 2007, NS Hashmi, Information Systems and Computing wrote: > Hi, do you have a demo in action?

Re: [Dspace-tech] streaming video?
If the presentation is to be served from DSpace then DSpace needs support for additional protocols. Otherwise every user will have to keep a pack of cards around so he has something to do until the entire video has downloaded and frame 0 appears. What we'd likely do here is to put both into DSpace: the stream pointer (for people who want to view it the same day they request it) and the actual content (for specialized uses, and to ensure that we have a well-labelled copy). We'd also prefer to use a streaming server that we control, so that our retention policies can be enforced. We're setting one up now. We've looked at using another unit's streamer, but that service is really for more ephemeral stuff and I don't think it's considered a serious alternative at this point. -- Mark H.

Re: [Dspace-tech] streaming video?
I have run into this need at our university as well, and the only really "proper" solution (in my opinion, of course) is one that would store the bitstream of the actual video in the repository. One of the most fundamental parts of a repository is that the data bitstreams are archived and managed in a central location. By having something like a .ram file which points to an external server, or an .html file that loads up the streaming media, this circumvents that management and can potentially lead to nearly useless records in the repository, even with the best intentions of the current managers of the various servers that store the media. It's essentially creating the same kinds of issues that the current web URL standards do - broken links due to server name changes and external reliances. In my view, a well-managed DSpace repository should avoid these issues by storing all the bitstreams within the repository itself.

Re: [Dspace-tech] streaming video?
Agree completely. Ideally, the video would be served and streamed from DSpace, or maybe the streaming server setup as a SRB.

Re: [Dspace-tech] streaming video?
Naveed, We're doing something similar, not using DSpace to store the video but to store a "pointer" to the streaming server instead. We use a RAM formatted file, but SMIL would work the same.
