Recording problem - johsmi - 2012-12-29
I'm having a problem with recording from XBMC and would appreciate any suggestions on how to fix it.
Recording of some channels is failing to start with a pop-up message "PVR backend error. Check the log for details...". Recording of the same channels works fine from the Tvheadend web gui. Watching the channels live works fine in XBMC. Recording other channels works fine in XBMC. I don't know what is different with the failing channels compared to the working ones.
I can't see anything in the Tvheadend log when the recording fails to start. (It's as if the recording is never requested.)
The XBMC log shows:
Code:
17:47:14 T:3132 ERROR: PVR - PVR::CPVRClient::AddTimer - addon 'HTS Tvheadend:192.168.2.1:9982' returned an error: server error

Hello,
I do have exact same behavior but only for channels with empty EPG. In debug mode:

There is nothing in backend log.
I tried : XBMC RC2 and RC2 d446c0a and tvheadend 3.2.18 and 3.3
Tks,

That's interesting. I just checked and I do have EPG info even for a bad channel. I just noticed though that recording worked fine when started from the EPG view in XBMC but failed when pressing the REC icon during live watching.
New debug log excerpt:

ok I guess we're hitting 2 different issues then
RE: Recording problem - johsmi - 2012-12-30
Maybe not completely different issues after all. I just upgraded to XBMC RC2 and my problem may have turned into yours. I was still not able to record on my first attempt but I noticed I had no EPG. After selecting "Update EPG information", I got some EPG data for the failing channel and recording then worked (even from clicking the icon during live watching).
The debug log from my first failed attempt now shows:
13:30:12 T:4628 DEBUG: AddOnLog: Tvheadend HTSP Client: CHTSPData::AddTimer - Error adding timer: 'Channel does not exist'
RE: Recording problem - johsmi - 2012-12-30
I just built and tested pvr.hts addon 1.6.9 from Git. No change.
RE: Recording problem - johsmi - 2012-12-31
I think I may have located something interesting in the addon source HTSPData.cpp. From the logs, epgid (=timer.iEpgUid) = -1 when there's no EPG. I'm thinking the if condition below will be true as timer.iEpgUid<>0. The else clause will not be executed and channelId will never be set. With no valid epg or channel, tvheadend function htsp_method_addDvrEntry will fail with htsp_error("Channel does not exist"). Comments?
Code:
if ((GetProtocol() >= 6) && timer.iEpgUid)
{
htsmsg_add_u32(msg, "eventId", timer.iEpgUid);
htsmsg_add_s64(msg, "startExtra", timer.iMarginStart);
htsmsg_add_s64(msg, "stopExtra", timer.iMarginEnd);
}
else
{
htsmsg_add_str(msg, "title", timer.strTitle);
htsmsg_add_u32(msg, "start", startTime);
htsmsg_add_u32(msg, "stop", timer.endTime);
htsmsg_add_u32(msg, "channelId", timer.iClientChannelUid);
htsmsg_add_str(msg, "description", timer.strSummary);
htsmsg_add_u32(msg, "eventId", -1);
}RE: Recording problem - xmeslin - 2012-12-31
I'm not code dev so cannot state here. Maybe the best is to open a case with your findings on http://trac.xbmc.org
In the mean time I use xmltv on backend to get a complete EPG.

Comments?this code is correct. it either needs the epg event id or channelid+start+end
the problem should be fixed in xbmc's current master. reset the pvr database if it's not fixed for you

Are you saying that setting iEpgUid to -1 to indicate no epg was a bug in xbmc code and that it should already be fixed in current master?

I will try building current xbmc master and resetting pvr database.
RE: Recording problem - opdenkamp - 2012-12-31
correct
RE: Recording problem - xmeslin - 2013-01-01
I just downladed the nightly build ffa3e48 and I still have the issue. Is it expected ? I thought the fix should already be in the master branch.
Tks,
RE: Recording problem - opdenkamp - 2013-01-01
reset your pvr database
RE: Recording problem - xmeslin - 2013-01-01
I did reset PVR database.

I just tried the nightly "20121231-ffa3e48" and I still see the problem too. My steps:
1. Install nightly
2. Reset PVR database
3. Uncheck "Activate EPG" in channel manager to remove epg info for one channel.
4. Watch channel live.
5. Press rec icon.
6. Fails with "Channel does not exist" and log still shows epgid=-1.
