Treiber / Re: CoreELEC mediasrv unhandled exception after build 20260819
« am: August 22, 2026, 05:00:57 Nachmittag »
Enabling CONFIG_SYSVIPC works. But the option will stay disabled. If we see issues later with other CE components we will need to find better solution.
But for now this is it.

I asked claude to make me LD_PRELOAD library. Seems it works.

Code: [Auswählen]
LD_PRELOAD library that emulates SysV IPC (shm/sem/msg) entirely in
userspace using POSIX shared memory objects + pthread PROCESS_SHARED
mutexes/condvars.  Intended for kernels built with CONFIG_SYSVIPC=n,
where shmget()/semget()/msgget() and friends would otherwise fail with
ENOSYS.

As I wrote there is a reason for this changes. And we will not go back until really needed by some other components.

Sadly enabling CONFIG_SYSVIPC is not an option. As I wrote we aligned linux config to android one because we use one kernel module from Android (dovi.ko for DV playback) and seems it helps with stability. We didn't saw any other issues in last few days after this change. If anything else pop ups then we could (and should) reconsider but for now it will stay disabled.

This means tuner will just not work anymore with this option disabled?

Treiber / CoreELEC mediasrv unhandled exception after build 20260819
« am: August 22, 2026, 11:17:01 Vormittag »
At CoreELEC distro we changed linux kernel config to be more aligned with Android. And now after the changes mediasrv crashes:
https://gist.github.com/vpeter4/a186efc29879357da4dcd47cf76c74bc

and "mediaclient -e" command just freeze and doesn't show anything

kernel config changes:
https://github.com/CoreELEC/CoreELEC/commit/1b69c09a5f

According to AI it is glibc memory issue:
Zitat
Given AArch64 calling convention (x0=arg1, x1=arg2, x2=arg3), this pattern — a dest/pointer arg of -1, a source of NULL, and a huge/wrapped length in x2 — is glibc memcpy/memmove/memset called with corrupted arguments. The -16 in x3 is also a classic glibc malloc chunk-header artifact (size field with flag bits). This smells like heap corruption or a bad size calculation inside mediasrv (buffer overflow, use-after-free, or an integer underflow producing SIZE_MAX-ish values)

Any idea how to proceed and get tuner working again?

Treiber / Re:Standby-Timeout anpassen
« am: November 01, 2017, 08:04:13 Nachmittag »
In addon settings there is an option Enable modifying settings (Geräte-Einstellung ändern) which is set to true by default. Make it false and then config file should not get overwritten.

And you need to edit file /storage/.kodi/userdata/addon_data/driver.dvb.sundtek-mediatv/sundtek.conf (file in addon home).

Let me know if this helps. If not I will check myself (currently out of reach for my tuner for a few days).

Sundtek MediaTV Pro / Re:Sundtek + Xtreamer Ultra + Openelec + tvheadend
« am: Oktober 19, 2012, 05:29:33 Nachmittag »
Es ist schwer zu debuggen, wenn ich nicht reproduzieren können diese selber. Aber Sie können versuchen, diese: wenn tvheadend nicht sieht ein Tuner versuchen, es in der Konsole neu zu starten:
tvheadend.stop
tvheadend.start
Sieht der Tuner dann?

Oder Sie können versuchen eine neue Version von Sundtek Addon:
http://www.sundtek.de/media/driver.dvb.sundtek-2.1.5.zip
Es gibt eine Option "Extra settle time" zu warten, bevor tvheadend gestartet.

Deinstallieren Sie alte Version zuerst.

This Sundtek addons are hosted on OpenELEC servers and can be installed directly from XBMC itself (no need to manualy download zip file and manually install).

But in this case the commit (https://github.com/OpenELEC/OpenELEC.tv/pull/1216) is not accepted yet that's why there is no addon in repository. When it will be this file will not be required anymore.

Because there is not much such users which would report info back the info is a little scattered  :(

I don't see any confusion here.

AndreasP69, why don't you ask this on OpenELEC forum and I could help you much faster (I'm the maintainer of sundtek addon for OpenELEC).

You can try to install this sundtek addon (untested): http://dl.dropbox.com/u/8224157/public/driver.dvb.sundtek-mediatv-rpi-2.1.4.zip

Sundtek MediaTV Pro (Europe) / Re:Apple TV + Openelec - no scan
« am: Mai 05, 2012, 05:42:16 Nachmittag »
Openelec works as it works. And addon works just fine as is with tvheadend and vdr. To run w_scan you just need to use this export. No big deal. It's only few times.

Great! Will try it out.

For now I just count the numbers of called device_attach. And after that I start tvheadend. Like user write back "Works perfect !"

« am: April 19, 2012, 08:37:58 Nachmittag »
Of course ;)

I was at work and before testing at home I investigate this thing.
In my addon for OpenELEC I have support for only one tuner. Now I add few lines to support multiple tuners. The problem is with tvheadend which doesn't use tuners if they are added after tvheadend is already running. That's why I first start this driver (mediasrv daemon) and wait for all tuners to appear. After that I start tvheadend which is then using all tuners.

Is it possible to use multiple USB Sundtek tuners at the same time? One tuner for watching while another recording.
