Hi all This looks like it could be very good value if Open Source drivers appear for it : http://www.xbox.com/en-GB/xbox-one/accessories/digital-tv-tuner#fb...

One of my colleague has an Xbox one, I have a tuner and a i2c sniffer, so next week I am going to sniff the i2c communication between the demodulator ic and the tuner with an Xbox. I tried it, the method is working with the linux driver, I can see what control datas the tuner get, so the next step is the same but with an Xbox.

@Andras

That sounds great! Will be interesting to compare the problematic frequencies. First question of course is, will you be able to watch all the channels problem-free using the Xbox itself? Then if yes, we should focus on the I2C communication.

Compiling and testing DVB-T on rpi3 succeeded on kernel 4.9.40-v7+, however I used a updated kernel (rpi-update and possible a bad usb media) in the first place that might break things. To let it compile with a updated kernel I had to add extra packages to fix the updated kernel sources/headers which needs to be added manually by rpi-source:

#update base image sudo apt update && sudo apt upgrade sudo apt install raspberrypi-kernel-headers make gcc git patch patchutils libproc-processtable-perl firmware-linux-nonfree bc libncurses5-dev libdigest-sha-perl #incase of upgrading the kernel 4.9.40-v7+!!! sudo apt update && sudo apt dist-upgrade sudo rpi-update sudo wget https://raw.githubusercontent.com/notro/rpi-source/master/rpi-source -O /usr/bin/rpi-source && sudo chmod +x /usr/bin/rpi-source && /usr/bin/rpi-source -q --tag-update rpi-source #this will get modified+ kernel sources and headers sudo reboot #!!!make sure you are currently running the kernel as you would like to build these modules for, otherwise reboot first!!! #clone media_build and patched xbox sources mkdir -p xboxtuner/attempt01 cd xboxtuner/attempt01 git clone git://linuxtv.org/media_build.git git clone --depth=1 https://github.com/trsqr/media_tree.git -b xboxone ./media #reset&build media_build cd media_build git reset --hard 258461908cbb83a4d2f869f0f70b6b511fce6baa #since 2017-08-08 commits break building V4L2/LINUX make dir DIR=../media make distclean cp ../media/mm/frame_vector.c v4l/ #otherwise building will fail on this! make -j4 #adding -j4 will make use of the quadcore in the rpi2/3 and decrease build time! #force install build kernel modules sudo make install #download the needed firmware cd /lib/firmware #dib0700 firmware is packaged in "firmware-linux-nonfree" sudo wget http://palosaari.fi/linux/v4l-dvb/firmware/MN88472/02/latest/dvb-demod-mn88472-02.fw #install tvheadend sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 379CE192D401AB61 echo "deb https://dl.bintray.com/tvheadend/deb raspbianjessie stable-4.2" | sudo tee -a /etc/apt/sources.list sudo apt-get update sudo apt-get install tvheadend #if the tuner isn't working yet by just inserting its USB plug than... sudo reboot;exit

I did exactly this. and yeah it worked. First step done to my headless tv server.

Next I´ll try your Image until I get a new raspberry.

Working for me in the UK from Crystal Palace - all 9 muxes working fine. (6 x DVB-T and 3 x DVB-T2)

@ C vH

Your Image works now. I Find Services Great work. Thank You for the work.

After a little while of testing a 4x XBox One tuner DVB-C setup I have noticed that there are definitely some signal issues with this tuner.

They don't perform anywhere near as well as an Astrometa MN88473 based tuner. Regular pixelisation.

I've tried adding a powered amplifier but I know if you're boosting a poor signal it often makes it worse, but I also don't think it's a poor signal in the first place (or certainly not too bad).

I also saw yesterday when TVH tried to do an epggrab on 3 tuners, whilst I was watching TV through another, the signal went through the floor with many errors. But strangely only on one mux - muxes either side were as before, very odd.

Maybe I need a better quality signal splitter, or to change how I route the cable to the tuners - currently using some screw on gender changers which I know aren't too great.

After testing the Image from C vH I must say it is the beste Libreelec that I ever use.
It all worked so fine both tuners work great and can record one channel and watch another. Never experience this. Now we need PiP in Kodi :)
i´m very pleased.

I have the original Astrometa (MN88472) and experienced the same problem on DVB-T again with only one mux - the strongest one of all. Now here's the interesting thing, both xbox tuners are connected to the same powered splitter using quality cables (with another 4+ tuners, all fine). The one (xbox tuner, using a cable that was made) is fine, the other with a high quality (sealed) cable glitched like hell, I switched it out with a cheapo poundland cable, and guess what, it's fine!

Make of that what you will.. (yes, I checked the cables were all connected correctly many times).

@C vH

how can I compile my own LibreELEC build with additional software?
I have a Mac

i have VirtualBox and Ubuntu Server.

But I can't find a tutorial on how to change the Software

It is pretty easyAFTER you understood how it works, before it is not that easy ;)

ERROR: Architecture not found, use a valid Architecture

for your project or create a new config

I get this error after doing it step by step so something I am missing?

TVHeadend has a "Low Noise Amplifier" tick box in the tuner settings. I'm not sure if these sticks have a LNA or if the option is implemented in the driver, but maybe that might help if you haven't tried it yet?

mpmc

Looks like I got a crash (leak?) with tvheadend using these tuners - I've opened an issue "here"

@olli Is this a bug with tvheadend or the tuners? I'm swapping them out for just the astrometa and an August T210v2, so I should be able to answer that myself eventually.

Just added a different type of amplifier and changed the gender changers/couplers to cables and whilst the problem hasn't gone, it's definitely better. I guess I'm just on the edge of it being good enough.

Hello,

Could we create a wiki page in linuxtv to share this documentation?

It will be great for other people that not use tvheadend and want to use this device in Linux machines.

Kind regards.

is it possible to install the driver on Rasbian on a Banana Pi?

It should be yes, I was able to build an armbian image on mine which is essentially Debian Jessie, and Raspbian is pretty much the same.

Josu Lazkano

Hello,

Thanks Olli for your work, it works well with DVB-C.

I installed in a Raspberry Pi with Raspbian Jessie Lite image and I am using with minisatip to feed tvheadend.

I can not find all channels, but I think that I must configure the muxes first.

Kind regards.

Looks like I'd spoken too soon, the cc errors later returned, so I started to investigate a bit more & remembered some tuners don't like power saving, which on my BPiM1/Armbian is (by default) set to ondemand, I changed this to performance and so far (last 30-45 mins) it hasn't shown any CC errors. So you may want to give that a try!

Anthony Thomas

Is there module argument that can be used to disable power saving? Or have you just done it through TVH?
Since I'm not using TVH on that system I'd need to do it the kernel module way.
