vlc's vod system only supports rtsp at the moment. One should normally
not need to set output with vod, and even if one does, vlc will
automatically append :rtp{...}, so the output line should only consist
of stream_out filters, like transcode or transrate (both of which is a
generally bad idea to use in VOD as it will transcode once for each
client wasting loads of cpu, so you should _really_ not give a output
line with vlc VOD)

It does not reencode the file, it just parses it to figure out the
needed streaming params. If it takes 5-10 minutes this can't be working
well for ogg files.

you can't connect to 0.0.0.0 . giving --rtsp-host 0.0.0.0 just means vlc
will listen for connections on all ips the server hold. The client must
give a real ip that the server can be reached at.
Furthermore http does not work here for above-mentioned reasons. Rtsp
doesn't work because you can't transfer ogg in rtp/rtsp (at least not
with vlc).

Put the files in a folder, and share with apache (or similar).

This is possibly a bug. To be examined.
