[vdr] Segfault in dvbhddevice

[Richard Scobie]

For the past few weeks, I have been running the current 1.7.XX version
of vdr with an S2-6400 card, using only one tuner, which is connected to
a 4 x 1 diseqc switch, without any problems.

The startup command has been:

/usr/local/bin/vdr -L /home/rs/vdr/PLUGINS/lib -D 1 -P dvbhddevice -P
femon -v /mnt/storage/video -s /usr/local/bin/pm &

Today I replaced my LNB's with dual output ones, with the second output
connected to a second 4 x 1 disecq switch, which is connected to the
second tuner on the S2-6400 card.

I removed the "-D 1" from the startup command and I am now finding that
sometimes vdr crashes on startup, with the following error:

Mar 7 17:40:46 atom kernel: [ 12.257270] vdr[755]: segfault at 0 ip
00007fd3118426d0 sp 00007fffcbf98968 error 4 in
libvdr-dvbhddevice.so.1.7.25[7fd311835000+18000]

If I then run the vdr startup command again, it starts OK.

Please let me know if there is any other information I can provide - the
current version I am using is vdr 1.7.25.

Regards,

Richard

Are you using the latest driver [1] and firmware [2]?

Hi Klaus,

Have the latest firmware - drivers were a week old so have just updated
them and the result is the same.

Seems to always segfault on bootup, then usually starts OK (with the
occasional seg fault) when manually started.

Here is a larger section of the log:

I notice here that it is only findin one frontend and it thinks the card
does not have MPEG decoder.

Here is the output from a correct startup:

I have found that adding a "sleep 5" to my startup script, between
loading the drivers and starting vdr, has caused it to successfully
survive five reboots.

Richard

I'm doing an udevadm settle --timeout=30 after load/unload, haven't had
any issues with that. Before I had that solution, I was polling for all
devices to appear under /dev/dvb, before starting VDR.

Cheers,

Udo

"udevadm settle" is a nice replacement for a sleep, something learned today, thanks. :-)

<Advertisement> ;-)
This is where the dynamite-plugin comes in (needs a patch for the vdr). It creates device-proxies so vdr can start
without the actual devices. dynamite listens on udev and attachs the devices as they got created.
This scenario was one of the reasons to develop that plugin...

If the environment is not too fancy (device bonding is not tested by me, I have only DVB-C/-T) it should "just work"...

I use it because it adds ways to detach cards from vdr, reload drivers
and use them again without stopping vdr.

Thanks again for this wonderful plugin !

btw, i haven't tested, does vdr-1.7.24-dynamite-subdevice.patch apply
on 1.7.26+(patches from the ml)
