[vdr] vdr crashes when replaying zero length recording

[Torgeir Veimo]

I've seen this a lot lately. due to tuning problems with my nova-t
500s, I've gotten frequent zero length recordings. Playing back these
either using the xine plugin, or xineliboutput, causes VDR to crash
and restart.

I'm using yavdr with only trivial modifications.

I compile VDR myself and never have this problem. I use vdr-xine and
have been test softhddevice but in case of an empty recording, VDR
just returns to live tv. Sounds like a yavdr problem -- last I heard
yavdr uses a bunch of patches but since I don't use it I don't know
that 100%.

Well that's always good and cheap to talk about things about any individual heard about ... :-(

@Torgeir

Which version of yavdr do you use? Might it be possible to open a case on vdr-portal.de in yavdr sub-forum? English language is pretty much ok, at least I'm able to answer ... ;-)

There is nothing wrong with passing along what you've heard.
Furthermore, I intentionally pointed out that I don't know that to be
100% true. Your claim that my comment is "cheap" is completely
uncalled for. If you wanted to reply, rather than trying to insult me
you should have clarified that YES yavdr applies patches to VDR, or NO
it does not.

Your claim that my comment is "cheap" is completely uncalled for.

Well, just needless, even you should realize that comments like this don't help anybody.

That's what I read: "Hey stupid I'm super cool and able to compile VDR by myself, you're a nobody just able to use this bullshit yaVDR ..."

And I guess I'm pretty much not alone with this impression, or did you had just a fragment of any helpful value for that guy ...

Then you're a complete idiot because that is NOT what I said.

Grow up.

Got some hints at the vdr portal on how to get debug output. The
crashlog contains this stacktrace;

I presume it would be cause by one of the patches yavdr uses, since it
also happens with only the xine plugin enabled. This is yavdr 0.4,
with latest updates as of today.

Hi Tor,

well honestly, I don't think it's one of the patches, it seems for me rather to be again somehow "vdr-plugin-extrecmenu".

The VDR version as of today has been tested since 2 month, to become part for stable-vdr (first lucid, then natty) and nobody did realize this problem. But I need to mention, pretty sure nobody did test extrecmenu, it isn't part of "yavdr-essential".

Could you please try to replay these recordings using the VDRs own functionality?

Regards
fnu

PS.: It would be much easier to chat about this in a thread in vdr-portal.de, instead of bothering this mailing list.

I simply temporarily removed
/usr/lib/vdr/plugins/libvdr-extrecmenu.so.1.7.22 (just negging it in
oder.conf didn't work) and restarted vdr-dbg. Here's the crashlog from
that run;
