Hi smp , thank you very much !

It worked in my RPi4 !!!

I had to do some changes to adapt the directories to my Raspberry Pi4, from the thread you've referred above

A quick summary for what I've done to put TBS 5520SE working with LibreELEC 10 in my Raspberry Pi4 - it my help someone.

( CvH , crazycat : The patch from smp is great to make TBS 5520SE Receivers to work with LibreELEC 10 )

Note: I used a VM with Ubuntu running in my windows PC to cross compile a patched LibreELEC 10 image:

- Clone libreelec 10 official git master branch:

git clone https://github.com/LibreELEC/LibreELEC.tv.git

cd LibreELEC.tv

git checkout

- Edit kernel config:

Edit projects/Rpi/devices/RPi4/linux/linux.aarch64.conf

CONFIG_DVB_USB_TECHNISAT_USB2=m

add this line --> CONFIG_DVB_USB_TBS5520SE=m

CONFIG_DVB_USB_V2=m

- Apply smp patch for TBS 5520SE:

download from smp provided link in the above referred thread:

wget https://www.dropbox.com/s/z8fphv11sfdpat5/linux-tbs5520se.patch?dl=1

copy it into projects/RPi/devices/RPi4/patches/linux/:

mkdir projects/RPi/devices/RPi4/patches/linux/

cp linux-tbs5520se.patch projects/RPi/devices/RPi4/patches/linux/

- Compile LibreELEC 10 and create image:

PROJECT=RPi DEVICE=RPi4 ARCH=arm make image

wait ... wait ... wait .... for some hours

The image will be in .\target directory.

use *.img.gz file and burn with libreelec sd-card writer tool.

RE: LE10 & TBS 5520SE on RPi4 // updated drivers (SOLVED)

]

I've been using LibreELEC 9.2.6 with Crazycats drivers in a RPi4

in order to give support for TBS 5520-SE receiver.

Today, I've tested a nightly build of LibreELEC 10, but TBS 5520-SE is not detected,

and Crazycat drivers are not available to select !

Is there any plans for the Crazycat's driver with LibreELEC 10 ? Or TBS drivers ?

(I've also tried to compile TBs drivers in the same x86 machine i've compiled LibreELEC 10 for RPi4, but not being lucky with the cross compiling ...)

try anther tvheadend epg module.

I'm in Lisbon time, my EPG work just ok, and I had no issue with the time changing in the past years - even when recording a program that crosses the moment when the time changes (last weekend of march, last weekend of october).

Have you setup the timezone using kodi interface ?.

[edit]

which epg module are you using ?

(it could be an issue with it)

As a reference, I only use tvheadend's "over the air: EIT: DVB Grabber"

Yes. The docker hub and git links are published in the first post.

I can take a look at the read me file, and try to adjust some points.

Well ... when I was preparing this addon, it was with the objective of someone entering trough the vpn, would work as he was in the lane, at home.

What you want to do, needs some adjustments at the routing level to avoid does accesses (I’m not ver proficient with that, sorry).

You could also define a iptable rule that refuses connections to the lan (or to samba port) when coming from vpn.

Tvheadend nightly builds for LibreELEC

Yes. it is the last tvheadend nightly version. It is working ok.

Just install as you would for any other addon. It will upgrade your current 4.2.X tvh version.

My two cents for the thread:

I have the following WORKING TV reception system:

I have a pi4 with an amazon powered hub, which as an independent 5V @4A PSU.

• Running LibreELEC 9.2.6
• The pi4 is powered by the hub trough the Header Pins.
• An external hdd and a tv receiver is connected to the hub, which in turn is connected to a pi4 usb port.

I've been using the following tv receptors (all with supported libreelec drivers) :

• tbs 5520se (DVB-S2 + DVB-C combo receiver) = awesome receiver (pity I've lost some money with the others);
• Hauppauge WINTV SOLO Hd -- works ok in DVB-C. But some small lost frames (reception / green artifacts errors);
• Geniatech / MyGica DVb-S2 (worst receiver I've ever used. works great for DVB-S, but very sensitive with S2 signals);

TV playback with TBS is very good.

I have no lost frames with the following configs:

• Whitelist 1920x1080 formats
• Adjust display refresh rate ON Start/Stop
• Sync playback to display OFF
• Allow hw acceleration MMAL ON
• During playback: Deinterlace method: AUTO

And the following configuration in:
/storage/.kodi/userdata/advancedsettings.xml

<advancedsettings>

<cache>
<buffermode>1</buffermode>
<memorysize>536870912</memorysize>
<readfactor>30</readfactor>
</cache>

<gui>
<algorithmdirtyregions>0</algorithmdirtyregions>
</gui>

</advancedsettings>

I hope this helps.

Quote from crazycat

Don't worry about legacy signal strength/quality in %. Usual this calculated in different way depend from developers

ok. thanks. But I'm not much worried with that.

But i am worried that with the new drivers, the device cannot tune any channels.

And that could mean it will stop working with libreelec in a near future...

Is it possible to confirm that the new drivers are still compatible with it ?

crazycat ,

After all, I was not compiling your last version, but one I had in my disk.

Now I've updated form your new gitsource GitHub - crazycat69/media_build

But now, the device cannot tune-in anymore !

The device which had the name in tvheadend as "Montage Technology DS3000/TS2020",

was now recognisable as "Montage Technology M88DS3103B", but incapable to tune in anything !

Reverting back to the old drivers, I was able to tune in, but with the old low signal issue.

Even with this low signal issue, is it possible to at least guarantee that the device is still supported (this, thinking in the future)?

Thanks.

I've downloaded you last media drivers and compiled them in osmc to test for different results.

But I'm getting the same low signal strength

Will it be a linux firmware issue for this device ?

thanks

Quote from crazycat

this old driver which use ds3k frontend driver.

Hi. thanks for your comment.

And there is no plans to update it ?

Any cheap usb receiver recommended for best results in Linux ?

I've just made as suggested, but no luck:

A new sdcard with LE for x86 booting in my PC.

Only Crazycats drivers recognise the device.

But the tuning is very bad.

A transponder that locks and plays perfectly when running within windows (with windows drivers, of course), cannot be locked when running in LE.

In an entire sat, only 2 transponders are locked by LE.

In the same sat, running in windows, there are tons of transponders and channels locked.

One could assume there is a linudvb driver issue (related to signal amplification ?).

At least for this device.

Please look at the dmesg above.

Bellow is the dmesg from LE in x86, with crazycats drivers:

Quote from Nicolas

Hello!

On windows your using x86 drivers and a PC or Laptop compared to LInux and Rpi4.

Have you tried x86 with Linux/LE?

Have you tried a powered USB Hub in the Pi to Power the Tuner?

Worth a Test to Tracks the Problem down.

Hi. Thank you for your suggestions.

Besides the receiver being self powered, I connect every USB devices to the Pi4 trough a powered USB HUB (which in turn has a 5V @ 4A PSU) in order to make sure that no issue comes from power issues.

I've also tried the same testing with a Pi 3 running OSMC without any other usb device connected, just to be sure.

All tests with a raspberry pi official PSU.

I've been using a Geniatech HDSTAR dvb-s2 usb receiver (self powered) in my Raspberry Pi 4 running LibreELEC.

recognised by dmesg as SU3000HD DVB-S USB2.0 //: Montage Technology DS3000/TS2020

firmware: dvb-fe-ds3103.fw

The reception has not been the best one on LibreELEC.

I've connected the same receiver to a Windows PC, and the signal and reception improved considerably !

My tests were with:

- raspberry pi4, libreelec: DVBLINK and TVHEADEND

- Windows 10: DVBLINK and SMARTDVB

using the same receiver.

Examples:

A transpoder with 10% signal in LibreELEC on the Pi has like 55% signal in windows.

A transpoder with 30% signal in LibreELEC (pi4) has 80% signal in windows.

In the end, I can watch channels in windows with top quality, that are impossible to lock in linux.

As if windows driver has some way of enable some sort of "amplifier" in the driver.

Is there way of adjusting the "power" in the linux dvb driver ?

Or an update to the linux driver that is not included in LibreELEC dvb drivers ?

This problem happens with all LibreELEC module drivers (crazycat, and "latest" included with 9.2.3. Standard drivers do not support this receiver)

I've attached a link to my dmesg in LibreELEC.

I have also a running dvb-c receiver from silicon labs. Please ignore it.

Only consider the dvb-s2 receiver.

That is true when running on a PC.

But having libreelec running in a RPi4 (as the case), and accessing it by ssh, parted and resizefs are already installed. No downloads, no installs, no other boots.

Or follow chewitt proposal above, for an even easier approach.

I use parted and resize2fs.

both included in libreelec and accessible via ssh.

Call parted and then use the following commands:

select (to select your disk /dev/sda ?)

print (show the size of the disks and partitions)

resizepart (to resize the partition to the new size)

quit

Then call resize2fs following the partition path (probably /dev/sda2, but you should validate-it yourself )

resize2fs /dev/sda2

reboot

Warning: You must be very careful using these tools, as you mich loose everything in your disk.

Post back your results

yes. of course.

it's kodi in top, that reports 30% CPU usage

Not other running services.

And yes: I've launched kodi with a clean /storage/.kodi/ just to make sure it is not a config issue
