Hello, I am setting up a media center based on XBMC and Ubuntu Linux (14.04 alpha and 3.13 kernel) My DVB adapter is a Pinacle PCTV 73A USB and it works on...

ProfYaffle

@Alasdair - another jolly wheeze - or a frig, depending on how you want to look at it ...

If tvheadend is simply getting confused by the adapter type, how about we override it, or maybe even set the configs up manually?

Shut down tvheadend (_sudo service tvheadend stop_ or equivalent) and navigate to @/home/hts/.hts/tvheadend/dvbadapters@. In here, you should find one entry per adapter - plain text - that you can edit. As a template, here's my DVB-T2 file:

hts@Server:~/.hts/tvheadend.backup.3.5.96~gaa0e5b1/dvbadapters$ more *20R { "enabled": 1, "fe_path": "/dev/dvb/adapter3/frontend0", "dmx_path": "/dev/dvb/adapter3/demux0", "dvr_path": "/dev/dvb/adapter3/dvr0", "type": "DVB-T", "displayname": "Sony CXD2820R", "autodiscovery": 1, "idlescan": 1, "idleclose": 0, "skip_checksubscr": 0, "sidtochan": 0, "qmon": 0, "poweroff": 0, "nitoid": 0, "diseqc_version": 0, "diseqc_repeats": 0, "extrapriority": 300, "skip_initialscan": 0, "disable_pmt_monitor": 0, "full_mux_rx": -1, "grace_period": 0 }

With that and what you have defined already, (a) you can see if tvheadend thinks the two existing adapters are genuinely different, or (b) you can modify one of them to be more like the above. It may just be a case of specifying DVB-T, for example, especially if it's labelled as DVB-C or similar now.

Worth a punt:sudo service tvheadend start when you're done (or, again, equivalent on your distro).

If that works, great. If it sort-of-works but we still get problems, the next step would be to do the same for the muxes, and see if we can bypass that config step as well.

Same routine - shut down tvheadend, navigate to @/home/hts/.hts/tvheadend/dvbmuxes/_dev_dvb_adapter<the_adapter_you_altered_above>@. Again, here's my mux list - you can see that they're named after the adapter and the relevant frequencies:

_dev_dvb_adapter1_Sony_CXD2820R474167000 _dev_dvb_adapter1_Sony_CXD2820R482200000 _dev_dvb_adapter1_Sony_CXD2820R498000000 _dev_dvb_adapter1_Sony_CXD2820R506000000 _dev_dvb_adapter1_Sony_CXD2820R522000000 _dev_dvb_adapter1_Sony_CXD2820R530000000 _dev_dvb_adapter1_Sony_CXD2820R538000000

And, in each one, the config:

$ more _dev_dvb_adapter1_Sony_CXD2820R474167000 { "quality": 100, "enabled": 1, "status": "OK", "transportstreamid": 12294, "originalnetworkid": 9018, "network": "Gloucestershire", "frequency": 474167000, "initialscan": 0, "bandwidth": "8MHz", "constellation": "QAM64", "transmission_mode": "8k", "guard_interval": "1/32", "hierarchy": "NONE", "fec_hi": "3/4", "fec_lo": "1/2" }

What might screw you here is whether the transport ID and network ID are the same everywhere in the UK. Might need some Googling.

Back to you...

ProfYaffle

@Saen - I think you should be able to do something similar. Navigate to the muxes directory as above, and check that the config of the non-working muxes is the same as the working one. If it's not, stop tvheadend, edit them and restart. You can also play with the config values if there's anything on the Internet that suggests that any parameter might be different.

Alasdair Campbell

@prof - Had a quick look before I had to leave for work and noticed the type set is indeed DVB-C. Will work on it tonight/this weekend and should be able to give you good news soon.

As both tuners are DVB-C/T/T2, is the type in the config file mutually exclusive, i.e. I can only specify one or other? If so maybe a developer could look into this.

You truly are worthy of the name prof, if you're ever in West London let me buy you a beer :)

Thanks again and I will update you later.

Saen Acro

I do frequency offset and some of transponders, work but on non-standard freq???

ProfYaffle

@Saen - it would help if I could see your whole config - screenshots if possible, please.

I'm still guessing here, but do you have "autodetect muxes" enabled?

Are you certain that you have exactly the right muxes for your aerial alignment, i.e. do you know 100% what you're pointing at? Have you tested with a normal TV - tune to the missing muxes, look at the channel information and see what frequency/mux information it gives.

And I'm struggling a little with some of what you're saying, I'm afraid... my Bulgarian is non-existent, however, so I guess we'll have to live with it! What do you mean by that last comment, though?

@Alasdair - always happy with beer, but let's get you working first :-)

Alasdair Campbell

@Prof no worries.

Okay got an update, disabled tvheadend, edited the adapter and changed from DVB-C to DVB-T, re-enabled tvheadend and it listed the muxes awaiting initial scan. Noticed adapter did not have the enabled box ticked despite it being enabled in the adapter config file. Marked the checkbox and clicked save only to find it's overwritten my changes and back at DVB-C. Thought we almost had it there.

ProfYaffle

What if you try it with adapter1?

If the C is appearing on 0, maybe the T is on 1. Perhaps.

Alasdair Campbell

Nice try but same behaviour exhibited on both.

When it's restarted the atapter win the web gui is disabled, and if I enable it my changes to the files are overwritten.

ProfYaffle

I'm running out of steam if that doesn't work... I'm now convincing myself that it's an openelec issue.

Going back on that thread, then... via this post: http://openelec.tv/forum/81-dvb-c-support/64897-duoflex-c-t2-recognized-as-s2

1. You're using Ultraman's media_build version, yes? or the pre-Gotham version, anyway...

Ref: http://mirror1.openelec.tv/tbs/3.2.4/

Ref: https://www.dropbox.com/sh/8eckh0dsguue506/8MinxEP2Fn

you could revert to the XBMC Frodo 12.3 version to see if that works.

2. You've enabled the media_build oddities? I'm assuming that's necessary as it was in previous versions... ssh in and

touch /storage/.config/enable-drivers-media_build.txt

Ref: http://openelec.tv/forum/83-dvb-s-s2-support/65107-images-for-tbs-media-build-s2-liplianin-dvbsky#77261

I can see that there's a dedicated media_build version that's separate from the TBS version... this may be enabled already, but it's worth checking

If either of these work, then it's a driver compatibility issue in the default OE build. Whether that will continue or not into the official 4.0 release, we'll have to see - there's been a long-standing issue with TBS cards, for example.

It may be that you end up with two choices:

1. Run your tuner on a separate server of some kind, to break the dependency on OE, or

2. Buy a different tuner that has better native support

... but let's see.

EDIT

If enable-drivers-media_build.txt is enabled, you should be able to see it in your Configfiles share. If it's not there, you can create it from there instead of ssh if you like.

EDIT 2

Don't forget to restart/reboot if you do have to/try creating this file. Obviously you'll have to do the same if you downgrade to 3.2.4 from pre-4.0.

Alasdair Campbell

Yep im running the Ultramons media_build, the card wasn't detected otherwise on the standard Frodo version I originally had on.

Have created the enable-drivers-media_build.txt file and restarted. Same behaviour exhibited. No difference in lsmod output

Not sure what you mean/where to find the Configfiles share you mention.

ProfYaffle

The Configfiles share is how the /storage/,config directory is published onto the network through SMB - so you can manage the OE box without using SSH (e.g. to copy over updates).

So it's not that... sigh. I suspect it is a driver issue, because of the talk I found on kernels and patching v4l for this device. Even on a 'buntu box, I think you get into recompiling v4l to support this card, and that means you inevitably interfere with other card support - at least, that's the TBS problem and that's why OE doesn't support it natively.

Did you try the 3.2.4 media_build version? Any difference there? (Admittedly starting to clutch at straws here...).

Alasdair Campbell

Just checked maybe im not using the media build.

On ssh login itr's reporting:

OpenELEC (official) Version: devel-20140125171439-r17148-gb48ea69

Pretty sure I was using the media build though.

There is no SMB share available on the network. Going to grab another copy of the media_build and re-install it.

Edit

currently downloading OpenELEC-Generic.x86_64-devel-20140202141332-r17590-gc438852

Edit

20140202 does not work. Created the USB, did the custom install to replace the kernel and system. Boot hangs just when it says waiting for network.

Trying his media build for 3.2.4 ION...

ProfYaffle

It's like pulling teeth, isn't it...

I also found this: https://tvheadend.org/d/1180-force-dvb-type?r=10872#message-10872

... but that creates a separate challenge of how to get the new tvheadend into OE - unless someone's done it already, you're into roll-your-own territory at that point.

(It's worth looking into the lack of SMB shares, btw - with those, you can simply copy SYSTEM and KERNEL over from a diferent system and reboot, no faffing with USB sticks).

Alasdair Campbell

Update:

Now running OpenELEC (unofficial) Version: devel-20140214223152-r17710-g2376c15 from https://www.dropbox.com/sh/8eckh0dsguue506/70D8HzESHZ/Normal%20Build as the Media Build version wouldn't complete booting.

Same Deal.

Checked out that link, yeah seems like new version of tvheadend can properly support combi cards now. As the Normal build boots and has the drivers installed for the card I think best route will be to attempt to update tvheadend.

ProfYaffle

It might be time to shift the conversation back to the OE forums, as this really doesn't look like a tvheadend problem.

The good (ish?) news is that it's possible that you don't need to completely recompile OE - you can swap out the tvh binary if you can build or find one pre-compiled:

http://openelec.tv/forum/79-tvheadend/68257-how-compile-latest-tvheadend-build-for-opnelec

And, failing that... can you get an aerial cable to your QNAP...?

Sorry I couldn't get it fixed for you, though.

Alasdair Campbell

Yeah from the link you added if I can get the correct version that now handles combi cards I may be able to compile it for the version I'm running and get it working.

Aerial to the QNAP lol, I've not taken it apart to see if there's an available PCI-E slot and space to hack the case to enable it, think ah'll go for the compile route when I find the correct version :D

Will let you know how I get on, as I said, Any time you're in West London ;)

ProfYaffle

FWIW - and if anyone else stumbles in to this thread - there seem to be updated tvheadend addons for OE here:

http://saraev.ca/tvheadend/4.1/

Untested, so I really can't vouch for them. They do appear to be bang up-to-date, though.

Alasdair Campbell

Hey Prof, thanks for the link to the precompiled TVH.

I now have the TV :)

Only issue is EPG is not displaying, but is listed on TVH Web GUI.

I definately owe you a few beers!

Alasdair Campbell

Never mind, EPG is there now.

Alasdair Campbell

Just noticed TV had disappeared again.

After checking noticed TVH had gotten downgraded to 3.4.27 from 3.9.383. Not sure if there was an update to the OE version and this auto updated.

Reapplied v3.9.383 and all is back to normal.

Not sure if there is a setting somewhere that auto-updates addons (as I haven't looked), but adding this here should someone experience similar behavior.
