Re: [Dspace-tech] Help with Video Streaming using files stored on Dspace
Hi Bruno, Not sure if this helps, I did an implementation a few years back that had the ability to move your player seek bar forward (pseudo-seek) for dspace 1.7.0/Mirage theme. Have a look at http://sourceforge.net/p/dspace/mailman/message/29547581/ You can see an example at http://lekythos.library.ucy.ac.cy/handle/10797/5826 All the best, Evelthon Prodromou On 01/28/2015 07:39 PM, Peter Dietz wrote: Hi Bruno, It's been discussed, but never solved.

Once YouTube is ready, the curation task could add some metadata to your item, and your UI just plays a youtube video. Your repository would still have an archival copy of the video.

[Dspace-tech] Help with Video Streaming using files stored on Dspace
Does someone have any experience on streaming videos that are stored on Dspace in a way that is possible to seek a timestamp? I've done some tests and i've managed to play the video, but i couldn't seek a specific timestamp. I've did some research and found out that it's because the methods which answers the requests don't have support for byte-range headers. Is this right? I've also found this article/library [1] that implements these kind of responses, and i'm thinking about trying to append it to Dspace code, but first i would like to know if someone have already done this (or something like this), and also if there is an easier way to achieve this.
