Hi,
All our video files are external datastreams in our Fedora repository.
Video data sits on a NFS share, in a BagIt structure, which is also
accessible over HTTP. During ingest, Fedora can access the files via HTTP
in order to create the externa datastreams. No checksumming is involved at
this time so this all happens pretty quickly. The NFS share is also
exported to our streaming server. So Fedora essentially brokers access to
the file, telling the streaming server which one to stream to the user and
then the streaming server does so by accessing it over NFS.
This is how it works right now, at least. This could change... You could
have the streaming server access the files over HTTP as well.
I'd be interested to hear how others are doing this too...
