Re: [Dspace-tech] Psuedo video streaming with item attachment and seeking enabled
I tried to modify the Content-Type header with mod-headers, but it appears that can't be done, even when I tried it in 'early' mode: http://httpd.apache.org/docs/current/mod/mod_headers.html: ... it is possible to set and/or override most headers, except for those headers added by the HTTP header filter, such as Content-Type. I'm guessing there must be somewhere in the dspace code that sets the Content-type in the response header to include a charset, but can't seem to find where that is.

Re: [Dspace-tech] Psuedo video streaming with item attachment and seeking enabled
Sara, We're still running DSpace 1.8.2 here. We're going to the DSpace 3 update sometime this year. We'll need to update and fix our code, and I think that the intern we have here now will take more meticulous notes about how this customization works. He's good about that. I do remember that there is a dspace.cfg parameter: xmlui.content_disposition_threshold = 8388608 Keeping this set to zero (not -1) was part of getting things to work. We have a custom BitstreamReader from 1.7 that fixes some bugs in that partial download code, but it hasn't been properly integrated with the newer versions of DSpace yet.f I can pass along notes from our upgrade to DSpace 3.2 later this summer. --keith On Tue, Jun 18, 2013 at 1:31 PM, Sara Amato sam...@willamette.edu wrote: I'm trying to get this working in xmlui, and find that while I can get the proper looking code on the page, e.g. video src=/xmlui/bitstream/handle/10177/62/Knopf.mp4?sequence=1http://localhost:8080/xmlui/bitstream/handle/10177/62/Knopf.mp4?sequence=1 width=320 height=240 controls= autobuffer= / the video does not play.

Keith, thanks for the heads up about the xmlui.content_disposition_threshold . I was unaware of that setting. I tried setting it to 0 and when that didn't seem to have any effect to -1, but still no luck. I'll be interested to hear how the upgrade to 3.2 works out.
