mythbackend -v

It'll produce a couple lines of output when it goes to try to record
something.

Ok I have since this post gotten CVS from 8/4 working fine. Program guide,
and live tv work great. I still for the life of me cannot get the thing to
record. I can mark shows in the guide, and it just never records them. If I
go to instant record I see a live preview in the window above, and it fills
in the show data perfectly. Whenever I hit start nothing happens. Is it
supposed to go to another screen from there?

When I back out of the instant record screen (after hitting start) I go to
watch recordings and it says sorry, no recordings available.

I logged the output of this using 'mythbackend -v -l /var/log/myth-be.log'.
I then started mythfrontend and went to instant recording. I started a 60
minute recording. Below is the log...

It appears that the proper DB entry is being made, but nothing is reading

Well, you provided a log of the backend starting up and running after the only
program that was scheduled to be recorded was already over. I really don't
see how helping you with that is possible.

I'm not seeing the same behaviour, but recording isn't working properly for me
either.

I upgraded from Slackware 8.1 to Slackware 9.0 this weekend. Prior to the
upgrade (read: complete reinstall) Myth was working pretty much perfectly.
Now, when I record, the tuner seems to go out of tune. The picture is black &
white and... I don't know to describe how wrong the picture looks. Definitely
looks out of tune. The sound seems to work. The whole program seems to record
this way (but it's unwatchable), and then watching LiveTV doesn't work (same
problem). If I fire up TVTime, the tuning goes back to normal, until the next
time I try to record something.

Was using CVS from last Tuesday before the upgrade, now it's CVS from Sunday.
Kernel went from 2.4.20 to 2.4.21 (maybe the bttv module broke?)

There were more entries than that one in the DB, I just snipped it for
brevity to illustrate that the DB entries were being made.

Let me try once more. I went into MySQL and deleted all entries in the
record table. I then cleared out my logfile. Here is the log of the
following events. I started mythbackend with 'mythbackend -v -l
/var/log/myth-be.log'. I then started the frontend with 'mythfrontend'. I
went to TV->instand recording. I did not change channels and it filled in
the program data fine. I left it at the default 60 minute settings, and
tabbed down to the start button. When I hit the start button, it stay on the
instant recording screen, and the focus moves back up to the small picture
of live tv. Nothing else happens. When I then go back to watch recordings,
it says no recordings are available.

So it looks as if the DB entry is being made. And the backend is running
when the recording is supposed to start. Any ideas?

Try using the program guide?

Same results. It flags the the program with a S. I guess for single record?
I select a program in the future, go to advanced recording options. Select
record only this occurance, and set it to use the livetv profile (which
works great for watching TV).

When the time comes for the show to start, nothing happens in the frontend.
There is a DB entry for the show, but no file is ever created in my
recordings directory (ext3 r/w). Anything else I can try? Is there some way
to manually test the recorder? Does mythbackend do the recording or another
program? Pausing live tv and fast forwardnig rewinding works perfectly.

Thanks for the quick responses!
Trey

What does the backend log say this time?

I've never emailed to this list before, so I hope it goes in the right
place.

I'm having the same problem as well. LiveTV works great, but when I record,
nothing seems to happen. My video directory is on a separate reiserFS hard
drive on a PCI controller. Here's what I get by just starting the backend:

Nothing is added when I start mythfrontend and go to the program guide.
It's 11:29p and when I record a program once that is one minute away, this
appears:

Lumpix is my hostname. It's now 11:35p. Nothing seems to have changed.
The show recorded still has an 'S' on it for single record. I've set
/media/tv as the location for my recorded shows:

---

-rwxrwxrwx 1 root root 0 Aug 1 22:32 nfslockfile.lock
---

No file has appeared for the recorded program. I don't know what
nfslockfile.lock is, but I'd imagine it has something to do with me sharing
the drive under Samba. I can create files in the directory as a regular
user no problem (I apologize for the stupid prompt; still configuring Linux
;):

It's now 12:04a. Nothing has changed in MythTV. There was no indication
that the recording ever started or stopped onscreen, as shown in this image:

http://www-users.cs.umn.edu/~lthomas/mythtv.jpg

One line has been added to the mythbackend verbose log at exactly midnight:

This is similar to what happened the first time I tried to record something.
I set MythTV to record three things over a four-hour period. When I came
back, the program guide had advanced four hours, but each program still had
an 'S' attached and /media/tv was empty, as it still is now. 'Watch
Recordings' said (and says) 'Sorry, No Recordings Available'. Now, if I go
to LiveTV, this stuff appears and my live TV directory starts filling up:

In other words, LiveTV works great. I have an XP 1800 with Gentoo Linux
running the default/vanilla 2.4.21 kernel. I have a Hauppauge WinTV PVR-250
and in mythsetup it's set to Hardware Encoding and Tuner 0.

Sounds like when you reinstalled Myth you may have configured it to use the
wrong cable tuning standard. Go into your backend setup and check your
"Channel Frequency Table" setting (under "General").

Hey Trey, are you using MythTV from the Gentoo emerge builds? I am, and
although it's the same version as the latest release, maybe it just doesn't
work.

Mind adding some debugging to the code? In
programs/mythbackend/scheduler.cpp, starting at line 193, I'd like you to do
this:

recordingList.sort(comp_proginfo());
cout << "start: " << QDateTime::currentDateTime().toString("yyyy-MM-dd
hh:mm:ss") << "\n";
PrintList();
MarkKnownInputs();
PrintList();
MarkConflicts();
PrintList();
PruneList();
PrintList();
.....

and so on, adding a PrintList() after every function it calls until the end of
that if clause. Then, recompile, and run mythbackend -printsched again.

FYI, this file is used by the backends to determine if they are using a shared
nfs directory to store files.

No, it's unused currently I believe.

Isaac, I changed the code to what you said. Adding PrintList() calls all the
way down to the return statement for that function. My C skills are rusty at
best, but it compiled fine and I re-ran 'make install'. I then ran the new
mythbackend binary with the -v flag. I used the frontend to schedule 2 shows
in a row on the same channel. Here are the results...

I guess somehow recordingList.size() is returning something > 0. But the
results can't be used? I am too rusty at C, and unfamiliar with QT to go
digging much further. Any more debugging I can insert? Thanks for the help
so far, it is much appreciated. And BTW Landon, I am using CVS for mythtv,
just about every dependency for it was built with emerge though.

Well, looks to me like recordingList.size() is 0.. Would you be able to join
the IRC channel (#mythtv on irc.freenode.net) sometime? Easier to debug in
real time..

Okay, I'll check that... but watching LiveTV works fine... it's only when a
scheduled recording tries to record something that it gets screwed up.

...Just checked the "Channel Frequency Table" and it's set correctly:
"us-cable" (even though I'm in Canada :) yes, I know they're the same
frequencies).

Today I noticed that the recording didn't really record... it was supposed to
record a half-hour program, but it only recorded about 2-3 minutes (~41 MB),
and the picture was out of tune, as before. Then when it hit the end of the
recording (I assume it was the end), the frontend hung.

Also just found that restarting the backend looks like it resolves the problem
as well...

...and I just tried recording the end of a program and it worked properly...
maybe the problem has magically fixed itself. That would be nice. :)

Now to find out why the picture controls (contrast/brightness/colour/etc)
don't work... :) (usually they show -1 when I hit the picture adjustment
buttons, other times they show the correct values, but the actual picture
adjustments are wrong... like Contrast shows 30%, but the picture looks more
like 50%)

It's only annoying because it was working fine before the reinstall :)

Solution:

After running the query that finds programs to record manually, I discovered
that mysql couldn't complete the query. Since I followed the Gentoo security
guide, I had severely limited the /tmp partition. I had it mounted noexec
and owned by root. My mysql server runds as user 'mysql'. The query uses
joins, which makes mysql try to make a temporary table in /tmp. This failed
due to write permissions.

Thank you everyone, for all of your help! I'm so glad to have a 100% working
myth install now. Keep up the great work!
