Fabian Lange commented on TIKA-1113:
------------------------------------
Hi,
this is partly Tikas fault as well.
the upstream detector has no support for video yet (todo) and such returns
"application/ogg"
next up is the tika mime detector, which detects "audio/ogg".
As this is more specialised it wins, and will cause the upstream audio detector
to kick in. as the file is a video, it will fail.
I tried to fix the magic file for audio/ogg but failed to do so (overriding
default mimetypes via custom etc didnt work)
I found that here https://bugs.freedesktop.org/show_bug.cgi?id=1002 is a mime
magic list for the ogg types that should be used
Could you fix the mime magic detector? a 400kb test file for video is here:
