I second that completely.
IMHO, the core VDR should move toward a multiple OSD capability. Maybe
the network separation between the back-end and the front-end could just
be a compilation setting (add a RPC layer at the correct place, as a
compilation option : no layer = current standalone setup; network layer
= VDR server + VDR clients).
This should provide a clean way to separate the responsibilities between
the back-end and the front-ends. The rest is a matter of plug-ins and
not over Klaus shoulders.
I agree that the hardware side of this is just the visible part (and a
good flame-war starter). The plugin architecture allows many things,
which is good. The limits of the core makes it hard to create a
network-happy VDR system (not a VDR machine, but a system of multiple
machines), which is the root of many incompatible and incomplete
plugins, solving all part of the problem (xineliboutput, remoteosd,
dummydevice, epgsync, remotetimers, etc.)
I just recently started using streamdev, for a bare EPIA ML6000 client
(diskless, no DVB device, just mobo + RAM + network). I think it's a
good (and cheap, silent, power-efficient) starting point for a
network-based STB. It's not perfect, but most of the imperfections come
from the plugins that must be added and configured, each separately, to
achieve a good VDR network STB.
It is already possible to have disks array, DVB devices, and all the
cables down in the closet, and as many clients we want behind each TV
set, with only a CAT5 cable and an IR sensor. That's just difficult.
Moving existing plugin code into the VDR core, and getting some out of
the core, into plugin, would do a lot in the "right" direction.
I trust Klaus to eventually get to it, and the community to provide good
plugins, providing a tremendous network STB system. I'm not impatient at
all, I know this will happen. The more time it take, the better will be
the solution, the longer it will stay.
I look at how my neighbours watch TV : DVB-S converted to an analog
signal recorded on a crappy VCR, sending wireless scratchy analog to an
LCD TV (which was really the top 5 years ago), one tape at a time, no
...and I'm really happy with VDR.
