           Summary: Kaffeine hangs with 99% CPU after half hour of DVB
                    recording
           Product: Ubuntu
           Version: unspecified
          Platform: i386
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: kaffeine
        AssignedTo: debzilla at ubuntu.com
        ReportedBy: Richard.Theil at web.de
         QAContact: kubuntu-bugs at lists.ubuntu.com


Platform: Ubuntu 5.10, stock install, universe/multiverse
enabled plus Kaffeine (also saw 17109/18072 btw.) and
appropriate codecs.

Hardware: AMD AthlonXP 1700 ("Palomino") on Epox EP-8KHA+
Avermedia 771 DVB-T Card (DVB-BT878 and MT352 Tuner)

Version: kaffeine (& -xine & -gstreamer) 0.7-0ubuntu4
kaffeine set to kaffeine-xine backend (to work around the
flaws with gstreamer like jerky motion and ghosted channels
for DVB in kaffeine (two bugs on their own...))

Severity: Grave. This bug renders non-reproducible
data useless when recordings of one-time broadcasts
get cut off.

Description: A DVB channel is set in kaffeine, immediate
recording is activated for it, then it is displayed in
the player tab. After roughly half an hour, the picture
freezes, the recording stops and the CPU use for kaffeine
goes to 99%. The rest of the system still responds fine.

Reproducibility: Haven't tried yet, lacking the time.
I considered this failure annoying enough though, to
warrant immediate filing, even if this happens only as
a 5% fluke. I also don't have permanent access to the
machine (it lives 'round my parents).

Further details: Recording has been done in the
Rhein-Main area of Germany from VHF Bocquet 1 at
198.5 MHz (Das Erste) over a room aerial that had
limited signal quality on that frequency (very rare
errors on blocks in the picture were observed), so
a codec issue with the live view might not be ruled
out.

Logs: Anticipating trouble, I ran kaffeine in a
terminal, excerpt below, annotated. Unfortunately I
didn't try to attach gdb or strace to the hung task.
