One is enough for now.

Why it's "multiheaded"? Because one wire can only carry limited amount of current. One molex connector (4-pin connector) has only one +12v wire. But PCIe connector has 3 +12v wires.

If you connect only one wire then it can not carry enough current for high end video cards. Actually high end cards have 2 PCIe connectors.

I'm not 100% sure about it, but one PCIe connector should be able to carry about 150W or so, that makes about 50W per wire. In our case we do not need 150W maybe 50W or even less. So only one cable should be enough.

PCIe x1 port on the motherboard can supply 10W for sure. It could be that it can provide up to 25W but I need to check it.
10W will not be enough, that I'm sure of.

So what did you do?

dmesg output is ok.

if "ls -l /dev/dvb" shows at least 4 adapters you are good to go.

Just remember, do not upgrade your kernel. You will have to compile and install driver again each time you install new kernel.

Arshvinder Singh Sehmi

The output of

ls -l /dev/dvb

total 0
drwxr-xr-x 2 root root 120 Jan 12 13:53 adapter0
drwxr-xr-x 2 root root 120 Jan 12 13:53 adapter1
drwxr-xr-x 2 root root 120 Jan 12 13:53 adapter2

drwxr-xr-x 2 root root 120 Jan 12 13:53 adapter3

I just noticed that I am having kernel 3.x and I was earlier using wrong file version of v4l i.e for kernel 2.x

Hmm... I did not notice that my driver has choice of kernel version.
I downloaded the latest version and it worked with my 3.8 kernel.

Did you use driver from CD? I have not even looked what the CD contains. I downloaded driver from internet. CD-s are outdated already the day they were made.

For playing I use XBMC.
Under System > Add-ons > Disabled addons > PVR clients > Tvheadend HTSP Client > Configure you need to set your IP, and user/password. If it's running on your local computer, then IP is 127.0.0.1, user/pass is the same you use for webpage.
Under System > LiveTV > General you must enable LiveTV.
And then you should be able to watch live tv with XBMC.

You can also watch movies, play music and do some other things.

There is also HTSP plugin for VLC:
https://tvheadend.org/d/1169-tutorial-using-the-vlc-htsp-plugin

I do not like VLC much and I have not tried it.

I use Tvheadend as server and use many XBMC clients in my house, running on windows, linux and raspberry pi.

Arshvinder Singh Sehmi

Please suggest me one more thing -

I have installed xbmc client at android tab. When I try to connect it to tvheadend. I get the following log in tvheadend System log. XBMC client automatically got disconnected of it owns. Where is an issue?

Jan 12 17:00:25 htsp: 10.0.0.11: Welcomed client software: XBMC Media Center

Jan 12 17:00:25 htsp: 10.0.0.11 [ XBMC Media Center ]: Disconnected

Jan 12 17:00:36 htsp: Got connection from 10.0.0.11

Jan 12 17:00:37 htsp: 10.0.0.11 [ XBMC Media Center ]: Disconnected

At Android Tab in XBMC, I am getting the messagee TvHeadEnd HTSP Client : Connection Lost Access Denied!

Please help!

srx srx

Might be WiFi signal problem.
Streaming video needs good and stable connection.

Arshvinder Singh Sehmi

I think Connection Lost Access Denied is not due to weak signal. There must me some access settings at TVHeadEnd that is denying access to this 10.0.0.11 client

Not sure what is that?

Arshvinder Singh Sehmi

Finally Got it working without any issue.

Thanks a lot to TVHeadEnd Team for providing such a great & valueable software for free.

Thanks & Regards,
ErSehmi!

Hi All,

Is there any options at server end to control and set the server buffering, or how to deal with buffering while using TVHeadEnd?

I am using HTSP plugIn with VLC right now!

Also, I need one more info regarding the TVHeadEnd System Log, when connected to XBMC Client -

an 12 21:58:25 subscription: "10.0.0.11 [ admin | XBMC Media Center ]" subscribing on "9X",*weight: 150*, adapter: "TurboSight TBS 6985 DVBS/S2 frontend", network: "DD DIRECT +", mux: "DD DIRECT +: 11,150,000 kHz Vertical (Default (Port 0, Universal LNB))", provider: "DD", service: "9X", quality: 100

Jan 12 21:58:25 TS: TurboSight TBS 6985 DVBS/S2 frontend/DD DIRECT +: 11,150,000 kHz Vertical (Default (Port 0, Universal LNB))/9X: MPEG2VIDEO @ #531:Continuity counter error

What is weight: 150, in the first line of SYSTEM log?

What are these continuity errors?

Please suggest!

Regards,
ErSehmi

srx srx

All buffering is done on the client side.

Look around in VLC, there might be option to set streaming buffer size.

continuity errors could be related to bad signal - but I'm not sure.

If there is just few here and there, I would not worry about it. All signals coming over the air will have few errors in it.

Weight in other words is priority. If multiple clients/tasks need to use one tuner, then weight comes into the play. If you look at the log, then you see that epggrab runs every now and then, and epggrab has weight 1. So when you watch a channel and epggrab wants to run, then your subscription (weight 150) outweighs epggrab and epggrab request will be denied. Or something like that.
