xnpvrcli - linux/unix client for NPVR

[tmrt]

Thanks for the quick reply, adding an empty xnpvrcli profile gave me some live TV.
Could you share your profiles as a base for my experiments?

Sorry for the delay. Here it is:

I have found that appropriate amount of "cache" is crucial for smooth playback. "sb" and "tsprobe" are used to deal with corrupted (encrypted) beginnings of recordings. Other settings are more hardware specific.

i'll be interested to try this, have ubuntu 11.04 on VMWare, however not really dealt with Linux... input would be good...

Can this app be run on a diskless client that boots from the server? What hardware would be appropiate in the low-cost segment?

Just because a computer is running linux doesn't mean it can magically play video better than Windows, in fact quite often Windows video drivers can get better optimized performance. The cost savings from linux are not the video card, it is the savings on the O/S itself and the fact you could probably build a system that boots from USB ~150.

ION's and AMD E-350's are still the entry level class systems, if you are building from parts you still want hardware accelerated video or very power CPU. Surprisingly Intel IGP machines run pretty well but VDPAU-supported Nvidea cards are your safest bet but always search first, video can be tricky to configure. Probably the best thing is try an XBMC Live CD in your PC to see what the PC supports, and then expect that the NPVR client for linux performance will be worse.

Does this mean that potentially at some stage it might be able to run on a JB atv2 with xbmc?

My goal was not to save money by using Linux, but to have a diskless absolutely silent client for the bedroom, I'v been told that running a windows pc from USB would work too slow. If that's not true the operating system does not really matter, the HW has to have enough power to handle HD but the screen would probably not be larger that 19".

When I had it running from my O2 joggler (further up) it booted the O/S from a USB stick and worked fine.

I see no reason why, with some effort, you could PXE boot a client and d/load the o/s and software.

sort of off topic, but has anyone thought about developing a addon for xbmc pvr and using nextpvr as the backend? then hopefully you could use nextpvr to record and get cheap ATV2s as the frontends. this would probably be the closest project to that....

+1 for that, but I think the question would be better directed at the XBMC crowd, and they seem to have their hands full with other backends (oh... that didn't sound right at all!).

XBMC+NextPVR would be a killer combination.

well the xbmc crowd is just devs, some here could dev a addon for nextpvr in xbmc. i may take it up, but i'd be starting from scratch, this project might be able to be used a lot though.
