Tvheadend

It's mainly because of the space available where my cable and satellite connections come in to the house.

I have 4xDVB-S2 satip server which fits in a small cupboard and I obviously need a TVH server to utilise that. The TVH server is elsewhere in the house.

After having kernel issues in the past with various tuner cards I like to keep things separate. The TVH server is also a Web and file server, I prefer to keep that stable and available. I utilised an old "nettop" to essentially create a cheap 4xDVB-C satip server.

Sorry to be dumb, but after messing around with this on my Ubuntu 16.04.2 server yesterday, I still couldn't get it to show in DVB adapters in TVHeadend.

git clone git://linuxtv.org/media_build.git
git clone --depth=1 https://github.com/trsqr/media_tree.git -b xboxone ./media
cd media_build
make dir DIR=../media
make distclean
make

Following these instructions, I then run sudo make install, which seems to install all the drivers.
Then when I modprobe tda18250, that takes just fine.
When I modprobe dvb-usb-dib0700, the terminal hangs and seems to do nothing?

Am I missing something? Granted, it could be something simple as I'm not as versed in Linux as everyone here. Any help appreciated.

Christian, this might be a silly question, but did you try to reboot? After make you could do a "sudo make rmmod" to remove the old DVB modules that might be loaded currently and only then try to add the new ones. Alternatively, you could just reboot the PC after "make install" to get rid of whatever was loaded....

If it still hangs, try modprobing the dib0700 with additional parameter "modprobe dvb-usb-dib0700 debug=9" and have a look at /var/log/kern.log (even after a reboot) to see where does it get stuck...

D'oh, I didn't try a reboot, I'm going to be kicking myself if that's the solution.
Thanks for the fast response, I'll give it a try when I get home tonight.

To echo what Olli has said, you can do it without rebooting but rebooting is the cleanest option.

Unfortunately I have the same issues with the "original" driver, but I will try to dump the registers under raspbian.

Can you implement "FUNCTION: tmbslTDA18250A_GetPowerLevel" in your driver?

Unfortunately, I don't know anyone who has an USB sniffer, and as I can see the USB sniffers are quite expensive to buy one just for fun

I made an LibreELEC image for the RPi 2/3 with that driver, looks working.
If anyone wanne try feel free http://cvh.libreelec.tv/Test/xbox/.

Thanks CvH, I was planning to, but now I don't have to. Will you compile it for x86 as well please?

Andras, ok, there's not much we can do then, except start to guess which registers to change but that's a neverending task. I'll do that power level thing a bit later, the next couple of weeks I'm very little in front of my PC...

yes generic compile is running but takes a while - btw didn't worked to backport the driver to 4.9 (see Slack)

Hello,

I am trying to compile the driver in a Raspberry I have this error:

pi@raspberrypi:~/media_build $ make dir DIR=../media
make -C linux/ dir DIR="../../media" 
make[1]: Entering directory '/home/pi/media_build/linux'

Am I missing something?

Kind regards.

As a relative novice at this, but who has got it working on a Pi3, it looks like you don't have lsdiff installed - which is a dependency for compilation?

Have you installed all the packages you need for building media_build - they are detailed here https://www.linuxtv.org/wiki/index.php/How_to_Obtain,_Build_and_Install_V4L-DVB_Device_Drivers

It's probably patch or patchutils you have missing?

@olli

Many thanks for your work on getting this tuner working (on Linux). I'm happy to report - after creating my own BananaPi Armbian image & including your git commits (as patches) to the build process - that the tuner from my initial testing with w-scan, works great on DVB-T!

I did have some minor issues, firmware failing to load, which was resolved by increasing the coherent_pool to 1M..

dmesg is here if interested http://termbin.com/orcc

Have both tuners now working fine, although tvh crashed for some unknown reason, installed corekeeper so I can debug it if it happens again.

Hi all,

Thanks for everyone's work getting the drivers done, it mostly works for me on DVB-T and T2.

However, out of three available T2 muxes (UK Crystal Palace) I can only scan one of them. The other two give the following output:

2017-08-03 22:14:21.191 subscription: 0044: "scan" subscribing to mux "586MHz", weight: 6, adapter: "Panasonic MN88472 #0 : DVB-T #0", network: "Freeview", service: "Raw PID Subscription"

and

2017-08-03 22:14:04.152 subscription: 003E: "scan" subscribing to mux "570MHz", weight: 6, adapter: "Panasonic MN88472 #0 : DVB-T #0", network: "Freeview", service: "Raw PID Subscription"

2017-08-03 22:14:09.154 subscription: 003E: "scan" unsubscribing

These are the only two muxes that won't scan, and they're the only two that show the "poll TIMEOUT" error. The settings are identical for each of the three T2 muxes.

Does anyone (Olli maybe) have suggestions on how to debug it?

Thanks again!

ian

[EDIT: I see what it is, the driver gives that poll TIMEOUT message when there is no signal. My signal is weak so sometimes the tuning fails.]

Hello,

this is what I get. so what can I do? I´m not capable of compile myself or such things.

Thank You for the really great Work.

@marcoraap
thx for trying, I got similar feedback from other sides so something is fishy :/
I try to build Ollies version to rule out some mistake at my patch.

What mux info are you entering? Avoid using AUTO if you can, I got away with setting the freq, and bandwidth to 8MHz

You stated you are running ubuntu 16.04.2, which comes with the linux kernel 4.8(if installed directly from 16.04.2 install media) instead of upgrading from 16.04 or 16.04.1 (both uses 4.4 kernel).

I was only able to compile and load this xbox tuner driver when using a newer linux kernel version 4.10.x which is default for ubuntu 16.04.3.

If you are still running 16.04.2 with kernel 4.8 please try to install the 4.10 kernel with the following command:

uname -a #check which kernel you are running
sudo apt-get install linux-generic-hwe-16.04-edge linux-headers-generic-hwe-16.04-edge #installs 4.10 kernel
#!!!
#maybe you need to install without the '-edge' part since 16.04.3 came out today and maybe edge installs 4.12.x

Than clean up the older compile with forced installed drivers for your current older kernel:

cd media_build
sudo make rminstall
make distclean
sudo apt-get install --reinstall linux-image-`uname -r`

Than reboot to your newer kernel, and verify its there:

uname -a

Than repeat the xbox compiling steps to install, you can continue from "make distclean" if you haven't altered anything in the media_build directory.

cd media_build
make distclean
make
sudo make install
#reboot wasn't necessary in my case

You're right about the lsdiff package from patchutils however did you get it to compile for the default raspbian linux kernel 4.9.x? Could you please share how you did it?

Please be more complete with your findings. What kind of network are you trying to scan DVB-C, DVB-T or DVB-T2 and which frequencies? Please post which version of tvheadend and the kernel comes with RPI libreelec image you are using?

Hello Stephen,

I am actually building the driver for the Raspbian kernel, it is getting so long to compile, I leave allthe night and it fail again. I installed more packages:

apt-get install git patchutils raspberrypi-kernel-headers libdigest-sha-perl libproc-processtable-perl

Now it is compiliung again so I will have a result in hours, I will comment here how is going.

Kind regards.

I currently try to rule out that the LE system is somehow influencing the driver (everyone is reporting the same that no data is working - everything else looks okay). Tvh and Kernel is at latest stable version so there should be no surprises.

pls try http://cvh.libreelec.tv/Test/xbox/ the 1.1 version of the image (now pure media_build offered from Olli instead of patch)

@Olli Salonen
Thanks for building a linux kernel conform driver, so far these are my findings for single DVB-T and multiple DVB-C use cases on ubuntu server 16.04 amd64bit with linux kernel version 4.10.28 from the HWE stack.

Just able to test DVB-T with service provider "Digitenne FTA Netherlands, Drenthe" and got it working although with a very low reception (5/10%). I had to sit outside with an external antenna(passive) and was able to watch 4 channels at the same time on the same 786MHZ mux. Other mux frequencies(506,546,570,738) did successful service scans here but I have no subscription to that. After a couple of minutes 3-5 some continuity errors come up. This might be just the case for this region I'm in right now as in bad reception in rural areas.

Remote testing multiple xbox as DVB-C tuners work like @Anthony Thomas already confirmed. Got that working on 3 tuners to scan muxes (even high frequencies) and work simultaneously on the same server using the service provider "Ziggo FTA Netherlands, Sassenheim". Although they seem to generate more continuity errors than other solutions.

I will do comparison tests with other adapters and older xbox drivers builds @Sky Anakin for both DVB-T and DVB-C next week, to compare continuity error performance.

Again thanks for pushing this!

For those asking how I installed the drivers on my Pi 3 - this is what I remember doing. I can't guarantee it's a complete how-to - but it's a good set of hints.

I first downloaded Jessie Lite Raspbian from here : https://www.raspberrypi.org/downloads/raspbian/

Flashed that to a Micro SD card, added an empty file called ssh (no extension) to the MicroSD card to enable SSH.

Booted up, let it do its thing then SSHed in (default login pi default password raspberry) and did :

sudo apt-get update

Downloaded Raspbian kernel headers :

sudo apt-get install raspberrypi-kernel-headers (Details here : https://www.raspberrypi.org/documentation/linux/kernel/headers.md )

Installed dependencies for building media_build

sudo apt-get install libdigest-sha-perl make gcc git patch patchutils libproc-processtable-perl following instructions here (Raspbian=Debian in this case) https://www.linuxtv.org/wiki/index.php/How_to_Obtain,_Build_and_Install_V4L-DVB_Device_Drivers

Then followed the instructions in this thread

git clone git://linuxtv.org/media_build.git
git clone --depth=1 https://github.com/trsqr/media_tree.git -b xboxone ./media
cd media_build
make dir DIR=../media
make distclean
make

There may have been some errors at this point regarding additional dependencies to add - I think I just sudo apt-get installed the packages in question that were flagged.

I then installed with sudo make install and rebooted with sudo reboot now

I then realised I needed firmware.

cd /lib/firmware

sudo wget http://linuxtv.org/downloads/firmware/dvb-usb-dib0700-1.20.fw (I found the link by googling)

sudo wget http://palosaari.fi/linux/v4l-dvb/firmware/MN88472/02/088b891ac9273ff8c6818fca27b24d81/dvb-demod-mn88472-02.fw (Again - slightly trickier - but found by googling)

sudo reboot now to reboot

These two firmware files need to be present in /lib/firmware as - I think - they are loaded onto the USB tuner when it is initialised by the driver.

I may have missed a stage out - if I get a chance I'll repeat it from scratch and update this post.

• EDITED to add firmware download

Please note - I don't claim this is a good way, the right way, the only way to do this - it just worked for me. I'm watching the Crystal Palace DVB-T/T2 muxes in London (with a rooftop aerial/antenna and a reasonable signal)

Smith Martin Neal
Thanks for posting your Rpi steps, I will try to repeat these steps however they do not really differ much from the steps I took earlier especially concerned possible kernel patching. But libreELEC also runs 4.9.34 kernel which '@C vH' was able to compile the module for.

@C vH
The v1.1 image (6023c32ff56c39d1f70a880895be5fb3 LibreELEC-RPi2.arm-8.1-xbox-dvb-driver-mb-1.1.img.gz) is not working yet for me on DVB-T, took the same tuner + antenne on the same spot (as with my netbook 1 minute before) and was not able to scan any muxes. I installed tvheadend(4.2.2-75 ~ LibreELEC Tvh-addon v8.2.111) from the addons (thought it was already installed on your image), however dmesg spits out these messages:

usb 1-1.3: DVB: adapter 0 frontend 0 frequency limits undefined - fix the driver
