Sundtek MediaTV Pro (Europe) / Re: /etc/ld.so.preload conflicts on ubuntu
« am: Dezember 17, 2018, 06:46:01 Nachmittag »
No unfortunately my xbox tuner is working fine with the same Ariel.

One really weird thing which makes me think it's a permissions issue is that I can see the adapter in TVheadend but when I select a Network and Network type it disappears until I restart Sundtek service. Here's the error log from Tvheadend
Code: [Auswählen]
2018-12-17 16:36:23.611 [  DEBUG]:satip: SAT>IP DVB-T Tuner #2 (172.17.0.1@UDP) - stopped control thread

Clearly this is not the same for the Xbox tuner which works fine.

Still unable to get this working and struggling to find any decent documentation to help out.

Here's what I have tried. All as sudo

Code: [Auswählen]
#remove all the old drivers
./sundtek_netinst.sh -u
wget http://www.sundtek.de/media/sundtek_installer_180626.045108.sh

installing remote control support
finalizing configuration... (can take a few seconds) 
Starting driver...
This system is using systemctl for starting the driver...
done.

#remove the dodgy preload
rm /etc/ld.so.preload

Then I modify the service to isolate the dodgy preload

"if you know what you're doing (and prefer to isolate it) you can just isolate it that way"

Honestly given the very high price of this unit (89,00 € currently) I would expect you to be a lot more proactive with your help. Libc is included with every single Linux distribution which makes me assume that their customer base is far far wider than yours. The expectation in this case is that you adapt to their changes, not the other way round. The bug you link to was reported in 2006 so they are clearly not in a hurry to resolve it and it also gave you plenty of time to come up with a fix yourselves.

Let's compare this workaround with your competition.

https://www.ebay.co.uk/p/Xbox-One-Digital-TV-Tuner-Xb1-Genuine-Microsoft/2255654535?iid=123475149092&_trkparms=aid%3D333200%26algo%3DCOMP.MBE%26ao%3D1%26asc%3D20140107084022%26meid%3D452b916268ae46ababd5a28c76c8bc06%26pid%3D100011%26rk%3D3%26rkt%3D12%26sd%3D173381285507%26itm%3D123475149092&_trksid=p2047675.c100011.m1850

So for £10.99 I get the equivalent of your product. Installation is simple, drop the dvb-usb-dib0700-1.20.fw into /lib/firmware and sudo reboot. That's it!

When I'm shopping around for products I always check out the support forums to know I will get after sales service, I assume others are the same.

I think you're missing the point here

tvrulesme@ubuntu:~/sundtek$ export LD_PRELOAD=/opt/lib/libmediaclient.so
tvrulesme@ubuntu:~/sundtek$ docker ps
ERROR: ld.so: object '/opt/lib/libmediaclient.so' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.
ERROR: ld.so: object '/opt/lib/libmediaclient.so' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.

So your meeting of an environment variable for LD_PRELOAD becomes accessible to all applications. Surely this is terrible practice. Even if it doesn't actually cause anything to fail it seems very badly written to me

Sundtek MediaTV Pro (Europe) / /etc/ld.so.preload conflicts on ubuntu
« am: Dezember 01, 2018, 09:32:27 Vormittag »
I have a Sundtek MediaTV Pro which used to be installed on a raspberry Pi.

I am moving to Ubuntu Server with the following os:
ubuntu:~/$ lsb_release -a
No LSB modules are available.
Distributor ID:   Ubuntu
Description:   Ubuntu 18.04.1 LTS
Release:   18.04
Codename:   bionic

There is a problem with ld.so.preload

But this causes errors for all other programs:

But if I comment the line wscan fails

Clearly this server is not only used for your Sundtek MediaTV Pro so do you have a fix for this conflict?
