Tvheadend

Working with workaround

Map DVB services to channels doesn't work but I could press press play in the services. The link didn't openen automaticly in VLC player. I copied the link and openend it with VLC player with "open network stream". After that i could watch the Free To Air channels from Dutch digitenne. Manually i changed the channelname (services), so they showed up in Channels.

After I downloaded XBMC with the addon PVR TVHeadend from http://xbmc.opdenkamp.eu/ after that I oould watch the channels on XMNC live TV, by a very friendly user interface.

I may have seen something similar. When I upgraded to git version 5d2197c30f (Dec 03, 2012) from a different branch version from August 2012, I found the same behavior that you are describing. I investigated a bit, and found that after the Mux scan was complete, none of the services got named: the "Service Name" column was blank for all services on the Services tab under the adapter config settings. I think this was causing no action to occur when clicking the enabled "Map DVB Services to channels" button. I am in the US and use ATSC. Downgrading back to the older version allowed me to scan the muxes again and have them be named automatically, then map them to channels.

Hope this helps...

If I'm correct, keep an eye out for Bug 1429. Just saw that one...

I'm experiencing this exact same behavior with a different adapter.

I'm on TVH 3.3.485~gf4dda1b. I'm using a HDHomeRun (HDHR3-US) for over-the-air ATSC broadcasts in the US.

I get blank service names too, and clicking 'map dvb services' will only insert this line in the log:
web interface: Service probe started on "HDHomeRun ATSC 1"

One other note - when I go back to an older version of TVH installed on my Synology (3.2.18~g40a8920) the problem is not there.

The problem is that US services (or HDHR, its not entirely clear which). Do horrible things that are not very compliant, and unfortunately we added stuff in 3.4 to improve performance in other areas. This appears to have caused issues with the ATSC/HDHR stuff.

But I would like to get to the bottom of this. Can you please provide a full debug log for both 3.2 and git master, starting from fresh and running through the setup etc..

Thanks for the feedback. I use a HDHomerun HDHR3-EU device now with DVB-C, the last time I scanned the service name was not empty anymore. When the service name is empty I just fill in the service name myself and after the services are mapped to service. Further the system is working. I use TVHeadend, Oscam as a server on my NAS DS211J with Smargo smartreader plus, I put my the smartcard provided by the cable provider in the NAS in combination with XBMC on my Notebook and PC and InstaTVPro on my Ipad, to view the streams, II can view the scrambled channels on my Notebook and PC, smoothly decoded by Oscam and I can watch the free to air channels on my Ipad because TVHeadend is not supported by Apple (in my case Ipad3) and InstaTVPro is directly talking with HDHomerun. XBMC Is also running and working on my Raspberry Pi in combination with TVHeadend on my NAS. However on a laptop or PC it is working more smoothly (faster). Practical the first HDHomerun channel is used by TVHeadend and the second HDHomerun channel used by InstaTVPro.

Hello Adam,

Thank you for your answer. I Have Connected a HDhomerun de device now. So basicly new architecture. See my post before. So I can provide no feedback anymore, because in the present situation it is working. But I see I was not the only one who had this problem.

If I can provide additional details to help track this down let me know as im having the same issue on my setup.

Using HDHomeRun Prime ATSC I can scan 248 Muxes (Standard center frequencies QAM256) and it finds an un-holy 539 unnamed services and clicking "Map DVB services to channels" spits a "web interface: Service probe started on "HDHomeRun ATSC 2" with nothing exciting that results from it.

I unfortunately don't even have the luxury of doing the workaround one of the users suggested by filling in the service names myself because when I click the "play" link after about a minute I get a popup option to download a link and I have no way of watching the streams to make any guesses. I randomly picked 100 services and add them manually to channels but when I try to view it in the built in VLC player I get a blank screen with "Waiting for video" on all of them.

Hello Tom S,

Do you run TVHeadend on a Synology Diskstation ? The VLC problem I recognize, I once used a workaround I copied the url from TVheadend and started VLC Manually, I went in the menu to Media after I selected "Open Network Stream" and pasted the URL, then it worked.
If somebody have TVH running on a Synology Diskstation in combination with A HDHomerun device, the link below can maybe help you. It helped me a lot. After I could choose the correct broadcast standard (DVB-T, DVB-C or ATSC)and the channels were recognized. A tip use XBMC in combination with TVHeadend, VLC is too basic.

Do we know if this is still happening, some improvements have been made that may mean some HDHR stuff now works. Though there is the possibility we will make more significant improvements in 3.6/4.0.

I was experiencing this exact same problem when I tried upgrading my Synology DS213 to TVHeadend 3.4 Stable Release. When I scanned for channels on my HD Homerun, over 150 services were found, but all of the service names were blank. I was able to play the streams in VLC, but I just didn't know what services were which. I was also unable to map any services to channels. Nothing happened when I clicked on the 'Map' button. I didn't try manually entering any service names, so I'll give that a try on my next day off. For now, I just went back to TVHeadend 3.0 and everything is working fine again. I am in the Los Angeles area, so my setup is ATSC.

Just an update that I was able to enter the channel names manually. What I did when I was still running TVH 3.0 was write down the multiplex and pid's of each service. Then after I installed TVH 3.4, I was able to easily figure out which channel was which.

I am having the same issue with 3.4 stable and ATSC channel mapping. The services are discovered just fine, but pressing the Map button does not pick up any channel names. As with others, previous versions of TVheadend worked fine.

I ran a fresh install of raspbmc which packaged tvheadend 3.4. Using an HDHR3-US with an OTA antenna, I was able to successfully scan for muxes, however I am facing the same problem described by a lot of the posts in this thread: Services are unnamed when the mux search finishes, and pressing the map DVB services to channels does not appear to do anything.

The debug log at the bottom prints:
Jun 14 22:07:57.608 web interface: Service probe started on "Tuner 2"

I'd be happy to provide more debug logs if it will help in further diagnosis.

@Alexei you grab a TS dump by clicking Play on the multiplex tab. It will start downloading a file so you'll have to cancel the download and copy the unfinished download someplace safe.

I am having the same problem with v3.4 stable and ATSC channels. Everything scans fine, but I can't map services to channels. When I click the map button, the debug log says:

If this bug is not reproducible in V3.3, is there a way to install the old version in Ubuntu (without compiling from source). Secondly, what is the workaround for this (is there a step by step for manually adding channels)? I'm trying to switch from MythTV - but if I can't get it to work, then I may stop investigating TVHeadEnd :(

Is this replaced code available in a stable build? How does one get a hold of this changed feature under Ubuntu (what repo is it?). Instead of closing the bug, isn't there another status that can be used until someone verifies that this feature works in the new version (which I'm assuming will be v3.6 stable)?

I can't use TVHeadEnd until this is working.:(
