Access TVcard from vps? [message #31456]

I'm about to install mythtv backend in a VPS, and add my Terratec Cinergy 1200 dvb-s card to the server.
As far as I can figure out it should be possible to access /dev/dvb on the HN from the vps by using something like vzctl set CTID --devnodes /dev/dvb:rw --save.

Is this at all possible? Anything I should watch out for?

Hi,

Have you bumped into any problems?
I think it should work.

It works perfectly. I've exposed the dvb-related devices to the VPS, and mythtv-backend handles them without any problems.

Spoke too fast.
It works good on low-bitrate streams (e.g zone horror, zone reality), but once I load up a medium-bitrate stream (e.g ITV2, BBC 1 London) the card can't keep up, and produce bit-errors.

Tested the card on a separate p4 2.4 ghz, same install of MythBuntu - no bit-errors.

Something(DMA)? Is destroying the datastream from the card.

My device - string:
DEVNODES="dvb/adapter0/ca0:rw dvb/adapter0/demux0:rw dvb/adapter0/dvr0:rw dvb/ad
apter0/frontend0:rw dvb/adapter0/net0:rw"

Tech:
Amd x2 4400+
8 Gb Ram
1,5 TB Sata2 HDD (3x500G)
Terratec Cinergy 1200 S Pci.

Does anyone have some good advice?
I'd really like this to work!

The last thing I'm going to try is to change pci-slot on the AMD.
If that does not work - Mythbuntu on bare metal; virt by KVM.

Did you get anywhere with this? May be too late but it may be worth fiddling with the PCI latency in the BIOS although that should affect the host OS too.

Well.. actually I did.. in a way. Smile

I tuned the bios, tried all the pci-slots and installed ubuntu on bare-metal. The problem did not disappear.

In my other PC (Dell optiplex GX260): No problem. No errors.

So I bought 2 TwinHans from Dealextreme ($41 a piece) - put them in the amd X2 server, and voila. The driver reports crazy errors, and basically 3% signal rate, but it works. Perfect picture.

So it looks as if the NEO motherboard and the terratec dislikes one another. Smile

Next step (today) is to install ProxMox 0.9 b2 again, and set up mythbuntu in a VPS. That'll give me a virtualized Mythbackend with 2 Sat-cards, and a secondary backend with 1 card. (total of 3 streams + 3 recordings completely independent. Smile

)

If that works... everything is brilliant. Smile

Will report back. Smile

(Maybe time for a howto?)

Oh yes please, a howto on installing mythbuntu inside a VPS would be excellent!

Be sure to include how you've setup the satelites!

Well - I've had mythbuntu working under openvz for a long time now; no problem.
3 DVB-S cards, all ok.
I'll compile a howto as soon as I get some spare time.

The basics:
- ubuntu 8.10 template
- apt-get install mythbuntu-desktop
- remove udev
- Edit the VEID.conf - add Devnodes(tv-cards) **
- Use Myth / XBMC on clients

regards argh

Wow , this is exciting, I have been wanting to run media center inside a container for a while. Please do share how you get it to work. and once I can lay my hands on a working model. I can be sharing more information with people who share the same interest.

By the way, are your just using the TV tuner to record video? where are you displaying the programs you want to watch? on another computer?

Well - it's not that hard really.

I've got 3 tuners installed on my server. These are all exposed to my container by the DEVNODES parameter. Basically I expose all the nodes in /dev/dvb (in the xxx.conf file).

I've installed a container with ubuntu 8.10 minimal openvz template, and then run apt-get install mythtv-server.

After that I install Freenx in the container, and connect to it to run mythtv-setup. Make sure the /dev/dvb/* are rw to the mythtv user. (Can also be done without freenx; if you're running X on another pc. (I'd love a text-based mythtv-setup!!))

I go through the setup, scan for channels on all cards and open the backend for remote access. (Set ip to real ip (not localhost), set pin to 0000).

As clients I use pc's with XBMC atlantis -> www.xbmc.org. (Native myth - support)

I have 2 clients running windows and xbmc, one running linux + xbmc and an xbox running xbmc. I also use mythtvplayer on my laptops. Currently working on getting easy access to video / livetv from my PDA and mobile.

I use mythtv as my only source of livetv - and sto schedule recordings.

As promised - I'll make a true howto; but it's gonna take some time. Small annoyances like work, wife and children tend to take up much of my time. Smile
