Kodi-PVR-MythTV and mythbackend settings

Sometimes you find a fix for a problem that's so simple you want to kick yourself.

I'd been unable to watch live TV streams on other frontends (OpenElec on Raspberry Pi, Ubuntu laptop, and Windows 8 laptop) around the house for several months. Having searched extensively and posted the problem on forums I could not seem to solve the issue.

Even though mythbackend would serve live TV to Kodi frontend on the same machine, I could not serve these streams across my local network to other machines running Kodi. The error message in the mythbackend log was "Client speaks protocol version 75 but we speak 77!" when attempting to connect from some devices (e.g. Raspberry Pi), and "Client speaks protocol version 8 but we speak 77!" when attempting to connect from others (e.g. Windows 8)

After some prodding around in the mythtv-setup options, I accidentally blanked out the IPV6 field in the "general" settings section. I then blanked out the IPV6 fields in the kodi-pvr-mythtv settings on the frontend client, and hey presto! It worked! Live TV streamed without issue.

What I found amazing was that this was a such a simple fix yet I had been struggling to overcome the live TV streaming for months. The reason it had baffled me is that in mythtv-setup settings the IPV6 field hint suggests that if I will be connecting to the backend from frontends on other machines then the field shopuld not be left blank. I hadn't really given this much thought other than, my Kodi frontends are on other machines therefore the field should not be left blank. In retrospect, I guess this hint refers to MythTV frontends, not other frontends such as Kodi, which is what threw me.

Best Kodi add-ons for use in the UK

There are hundreds of add-ons for Kodi. Many don't work, some give you access to content which is illegal to view in the UK such as copyrighted movies, sport and television series, and some seem to just be too niche to be any use to most people in the UK (Gun reviews in Russian anyone?). Amongst them are some gems. Here is a post to help UK Kodi users find the diamonds in the rough.

BBC iPlayer This essential add-on allows streaming of live and BBC TV and radio and catch-up TV from the iPlayer database. It has a much simpler menu system than the layout on BBC's content-heavy iPlayer website, which is either a good thing or a bad thing depending on your preference. Personally I like its simplicity and aside from Cmyth (see below), this is my most used add-on.

ITV Player Again, another essential add-on for UK viewers. Not quite as slick as the iPlayer add-on in terms of menu layout, but still easy to use, and allows streaming of live ITV broadcasts across ITV1, ITV2, ITV3 and ITV4 as well as streaming catch-up TV from ITV player's database.

USTVnow UK viewers can get live (HD for several months before reverting to SD) access to 6 US channels, for free. ABC, NBC, Fox, CBS, CW, and PBS). OK, this one is a bit of a grey area as it is designed for US citizens living abroad, and requires you to tick a box saying so. However, the only time I use this add-on is when my American pal visits to watch the superbowl. That's my excuse and I'm sticking to it! If you visit https://www.ustvnow.com/ and sign up for free registration, you can then add your username and password to the USTVnow add-on settings and the add-on will stream these free to view channels in Kodi.

Youtube Allows quick and easy access to Youtube direct from 

Kodi. Unfortunately, Youtube seems to have limited access to some DRM-protected content such as official music videos, meaning they can't be viewed from Kodi, but you could view them via a browser. Nonetheless, still a useful add-on.

Radio If BBC radio isn't broad enough for your listening tastes (Zouk, anyone?), Radio gives you access to hundreds, maybe even thousands (I haven't counted - let's just say, lots!) of international radio stations, which you can search by popularity, genre, topic, country, city, language, or search for local stations.








FilmOn Allows access to free to air channels from UK Freeview and many others around the world. The picture quality is not particularly good, but this is made up for by the range of channels available.









Spotimc You'll need a premium Spotify account for this to work. If so, installing this add on lets you search for music, browse for music and play your favourite playlists, all from inside Kodi.





This is just a small selection of the Kodi add-ons out there, and these happen to be my most often used ones. I also use a MythTV add-on which connects to my MythTV backend for me to watch and record UK Freeview TV and Radio.

Hope this list has been of some use to other Kodi users in the UK.

Steam-ish machine

Steam Machines' future is reported to be in peril as a result of delayed releases and Windows 10/Valve announcements (http://www.pcworld.com/article/2877281/why-the-steam-machine-revolution-may-fizzle-out-before-it-even-starts.html). However, my Steam(-ish) machine is here right now, and here's a report.

A quick recap: my linux (Ubuntu-based distro) HTPC sits in my lounge in ye-olde case (13 year old, Evesham X case), next to the television. I chose components to get a good balance between performance, low noise and low-power usage. The CPU is an AMD FX-8300 and GPU is an Nvidia GTX-650. This means the system can run games such as The Witcher 2, and Metro Last Light at medium/high settings, yet can be left running 24/7 without high power usage and too much noise (HDD soon to be replaced by SDD, and GPU fan to be replaced, which should reduce noise to practically inaudible).

Steam for Linux is installed on this PC, and runs absolutely fine in Desktop mode. However, Big Picture Mode frequently crashes, usually when viewing video, so I rarely go into Big Picture Mode, which is a problem, as Desktop mode is so hard to read on my television from about 8ft away. This is a real shame as Big Picture mode's layout is very good as part of a living room PC. Big Picture Mode also seems to be very resource-hungry, even after lauching a game; so much so, that when launching Metro or The Witcher 2 from BPM, the frame rate is so low the game is unplayable. Switching to Desktop mode and launching those same games resolves the issue.

I use an Xbox 360 wired gamepad to play most games now. Any games that require mouse and keyboard, particularly FPS, range from virtually impossible to slightly clunky with a Logitech K400 keyboard, as it has a trackpad, and a small one at that. Fortunately, most WASD games I've seen being released on Steam these days, support gamepads.

So what is the experience like compared to dedicated gaming consoles? Well, I'm sorry to say, that whilst I get on well enough with Steam Desktop version (as long as I sit close enough to read text!), Big Picture Mode just doesn't feel as sound as I'd like it to be. Admittedly, my machine is configured to do a lot more than just run Steam, but when I trim down running processes to test Steam I still come across the same issues; the main ones being Big Picture Mode crashing, and its resource-hogging. Once these are resolved, I would be quite happy to boot into Steam BPM by default.

The range of games is on Steam for Linux is growing larger and larger all the time - Steam is now listing 939. With recent major titles such as Metro, Dying Light, Borderlands: The Pre-Sequel, Football Manager, Sid Meier's Civilization series, and The Talos Principle, to name a few, the quality is getting better too. Hopefully this year will see more and more AAA titles being released on Steam for Linux, as this will surely prompt Valve to iron out those bugs on Big Picture Mode sooner rather than later.

BBC iPlayer add-on for Kodi, and Channel 4's 4oD

After being stopped by BBC several months ago, I've just noticed that the BBC iPlayer add-on for Kodi is working again. I can now watch live BBC TV and access all iPlayer's catch-up recordings via this add-on.

This is good news as I no longer have to access it via browser - the Kodi addon works so well and is far easier to navigate and find programmes than BBC's own iPlayer web site.

If only Channel 4 would allow such third party access to their 4oD service, too. I appreciate it is available on Windows PCs, iOS, Android, some games consoles, Smart TVs and set top boxes, but Channel 4's use of DRM restricts access to viewing via one of these devices. So, my only way of accessing 4oD is via Android - not a great viewing experience! Come on Channel 4, please open up http://m.channel4.com/4od/ once again so that third party 4oD apps can work again. I've tweeted Channel 4 with this request and on the form at http://www.channel4.com/4viewers/contact-us. You could do the same if this matters to you, too.

Kodi and UK Freeview TV

OK - so after a few months of not attempting to fix/get around some roadblocks in terms of streaming live TV to XBMC frontends, and no sound on HD channels, I decided to revisit my nearly complete HTPC for one last stab.

And, hey presto, I've made good progress and I'm really pleased with the setup as it stands - still some tweaks I intend to make, but I have a funny feeling I'll never be satisfied with the status quo.

So, I'm using Ubuntu 14.04.1, Kodi (formerly known as XBMC), MythTV as a primary backend server, UK Freeview DVB-T2 being tuned by TBS6285.

The rest of the kit can be seen in my previous posts.

I managed to resolve the HD audio issue simply by going into Cmyth-PVR addonn settings in Kodi, and under advanced, deselecting the de-mux option. I'm sure I tried this several months ago, to no avail, but it seems to have done the trick this time. So, now I can hear TV audio on all digital channels.

I'm able to stream to another PC in the house running Kodi as a frontend, simply by adding the CMyth-PVR addon. I couldn't achieve this using a Rasperry Pi with Openelec - for some reason that version of Cmyth just wouldn't allow primary backend and Rapsberry Pi to talk to each other.

All in all, I am really impressed. Live TV channel changing in Kodi seems to be quicker than when I last tried with XBMC in summer, and whilst not what I would called instant, it is acceptable - probably 2 - 3 seconds for the new channel to buffer and then play.

The picture quality is excellent, in HD. I did have to play around with a few variations of settings in Kodi's hardware acceleration settings section and in the onscreen display video settings section. I finally settled on auto interlacing, auto interlacing method, and auto video scaling. The quality and frame rate is excellent.

I also spent some time re-ordering channels on the mythbackend. I did this by opening a terminal and typing mythtv-setup. In the options menu that appears, select Channel Editor, and then work through the channels amending as you see fit. I've removed all the shopping channels, dating channels and all SD channels that have an HD alternative, and moved them into my preferred order. After this, mythbackend needs to be restarted, then open Kodi LiveTV settings and ensure "Always use the channel order from the backend/s".

I'm using a Logitech K400 wireless keyboard to control the HTPC and somtimes theYatse android app to control Kodi, This sounds complex, but it works really well. e.g. keyboard is on other side of living room, no problem - you can still control Kodi without the massive effort of rising from your chair and walking 3 steps across a lounge!

Cheap XBMC remote control

The Telegraph: KAZAM releases phones for under £40. http://google.com/newsstand/s/CBIww7b1nB8

The Trooper X 3.5 retailing at £39.95 could make an ideal XBMC remote control once Yatse is installed. Especially if it could be placed on a charging dock overnight.

TBS6285 Part 2

Following on from my previous post http://ubuntulinuxhtpc.blogspot.co.uk/2014/05/tbs6285.html I've received the quad-tuner and installed it, having overcome a few hurdles. I've described the process I followed, below. If you can't get this card to work, feel free to get in touch, and I should be able to help you get up and running.

The first hurdle to overcome was installation of the linux drivers for the TBS6285. These can be downloaded from http://www.tbsdtv.com/download/. After help from Constantine, developer at Turbosight (TBS), it turned out that my motherboard (MSI 990FXA-GD65) is one of many faulty ones floating around (there is a buggy ASM1083 chip soldered between PCIe and PCI bus) which cannot handle IRQ from the card and causes an interrupt storm from the card. To overcome that I did the following (from http://www.tbsdtv.com/forum/viewtopic.php?f=52&t=7631#p24903):

1. Create a .conf file 

sudo gedit /etc/modprobe.d/tbs.conf

2. Edit contents of .conf file by inserting the following two lines and saving file

options saa716x_tbs-dvb int_type=1

options saa716x_tbs-dvb enable_ir=0 

The first line activates MSI (Message Signal Interrupts) instead of the older IRQ. The second disables remote control receiver on the card to make sure the interrupt storm is not coming from there).

3. Reboot to load the driver with MSI loaded.

Then, following intructions from http://www.linuxtv.org/wiki/index.php/TBS6285#Making_it_Work and http://www.linuxtv.org/wiki/index.php/TBS6284 with a few amendments for TBS6285 and some permissions problems, I managed to get the card working. These are the commands I used:

1. Extract the ZIP file tbs-linux-drivers_v[VERSION NUMBER].zip. As of 25 April 2014, the latest version is 140425.

unp -u tbs-linux-drivers_v140425.zip

2. Extract linux-tbs-drivers.tar.bz2 archive

cd tbs-linux-drivers_v140425 

unp linux-tbs-drivers.tar.bz2

3. Change ownership and permissions of extracted files

sudo chown -R <yourusername> tbs-linux-drivers_v140425

sudo chmod -R 777 tbs-linux-drivers_v140425 

4. Change to driver package directory

cd tbs-linux-drivers_v140425

cd linux-tbs-drivers

4.1 (If on fresh install on CentOS or similar)     

yum install kernel-devel-`uname -r`

cd linux-tbs-drivers

make clean

make distclean

 (move to Step 5)

  
5. Select platform architecture
(for any x86_64 kernel only)

enter into a terminal: 

./v4l/tbs-dvbc-x86_64.sh

and then:

./v4l/tbs-x86_64.sh

6. Build the driver. Recompiles v4l for a wide range of cards, around 500, will take many minutes.

make

        (I modify this to make -j7  to use all 6 cores of my CPU)

7. Install driver

sudo make install

8. Reboot, then
(Ubuntu-based distros only. See http://www.linuxtv.org/wiki/index.php/TBS6285#Making_it_Work for other distros)

sudo rm -Rf /lib/modules/<your kernel version>/kernel/drivers/media

9. Reinstall drivers

cd tbs-linux-drivers_v140425 

cd linux-tbs-drivers 

sudo make install

10. Load newly installed driver

sudo modprobe -v tbs62x0fe

insmod /lib/modules/3.(your kernel version)-generic/kernel/drivers/media/dvb/frontends/tbs62x0fe.ko

11. Check it loaded correctly

Reboot:

sudo shutdown -r now

After rebooting and logging back in, check to see if dvb adaptor nodes now exist:

ls -al /dev/dvb

You should see something similar to the following displayed in your terminal:

drwxr-xr-x  2 root root  120 Jul  9 21:12 adapter0

drwxr-xr-x  2 root root  120 Jul  9 21:12 adapter1

drwxr-xr-x  2 root root  120 Jul  9 21:12 adapter2

drwxr-xr-x  2 root root  120 Jul  9 21:12 adapter3

This should give you a correctly installed TBS6285 on Ubuntu 14.04 (after trials and tribulations, it did for me!)

TBS6285

Ordered a TBS6285 today.

Should arrive in a week or so.

This card, once plugged into a spare PCI slot, should allow viewing/recording of 4 different mulitplexes at the same, and can tune to 4 channels within each multiplex. So, it's technically possible to record 16 channels simultaneously with this card. I can't ever foresee the need for that, but the option to tune to 4 different multiplexes will be.

Once it arrives I'll post further updates on how I get on with using it in XMBC. I plan to do a fresh install of Mythbuntu, too, to see how it compares to XBMC as a back-end server.

What remote are you using with Kodi?

As mentioned in a previous post the Yatse app for Android has really impressed me and I've been using it as my main remote control for Kodi.

However, it may not be perfect for everyday use as I've regularly been running down my phone's battery, which is not ideal as it then needs plugging in to a charger, which then means it's not accessible as a remote control.

So, what is everyone using as their primary remote control for Kodi? I wonder whether the Logitech K400 keyboard is a viable alternative - it is smaller than a full size keyboard and includes a trackpad. I wonder whether it would be too unwieldy for day-to-day use though...

I've read about Logitech Harmony remotes, but am concerned about reports of button lag. Does anyone have any experience of using one of these with Kodi?

Maybe I should just nab a Microsoft MCE remote control for £20?

Please do comment on how you are connecting to Kodi.

Silence is Golden

In an effort to keep noise down I've replace the stock AMD CPU cooler with a Scythe Mugen IV which seems barely audible. The only other fan in the case is in the PSU (Corsair CX600M) and on the graphics card (MSI GeForce GTX 650 N650-1GD5/OCV1), both of which were chosen as they were described as low noise. However, there is still a noticeable "hum" coming from the case which can be heard when nothing is playing. This is not a problem when media is outputting sound but it can be heard during silent parts of films which is distracting, and is certainly distracting when TV is off (PC is left running 24/7).

I'll be investigating what the culprits and attempting to decrease noise either by looking at replacement fans, or by replacing the component itself.

According to Kitguru's review of the Corsair CX600M it is barely audible until being pushed hard, which mine shouldn't be as I have the motherboard (MSI 990FXA-GD65) set to run in ECO mode, and I estimate the total power draw should be less than 50% of the PSU's capacity.

Watch live terrestrial UK TV and catch-up TV on XBMC

As well as watching your film and listening to your music collection, XBMC's add-ons are a great way of being able to access content on the web including access to UK Freeview live TV and radio streams and catch-up TV including the BBC, ITV and Channel 4.

The process is straightforward enough, with plenty of guides on the internet, but here is one which I found really clear and easy to follow (thanks to Jamestonbradley).

Once you've added the relevant add-ons, you should be able to view UK TV (BBC content is intended to be viewed in the UK only, so if your IP address is non-UK, you may not be able to view BBC streams).

This should also give you enough practice with video add-ons to be able to search through the hundreds of other add-ons available to see if there is anything else that is of interest to you e.g. MTV music videos, IMDB movie trailers, various kids TV channels, classic movies, extreme sports, cooking, the list goes on... have a look here to see a list of some of the video add-ons available.

Yatse - XBMC/Kodi remote control app

I've been using Yatse remote control for several days now, and I'm impressed.

Yatse is an Android app which allows you to use your Android device as a smart remote control for XBMC. It stands for Yet Another Touch Screen Experiment.

The free version is very full-featured: it allows you to do what you expect i.e. control the cursor in XBMC and make selections, but also displays info on what you are watching (i.e. displays info, posters, fanart on the remote/Android device), allows you to search your media collection using your Android device, control several different XBMC devices independently of each other (all within the same WiFi zone), amongst many other things.

As mentioned, you get all this for free. There is another app from the same developer (Tolriq) called Yatse Unlocker which is £3.49 from the Play store, and this goes even further, allowing you to send your videos to XBMC, stream videos to watch on your Android device, download your media to your Android device for offline viewing.

You really do need to try it to see how slick it is. I briefly tried the official XBMC remote, but couldn't get it working. Because Yatse was so straightforward to set up and works so well, and seems to win when reviewed and compared against other remotes, I'll be sticking with it.

Gotham!

http://xbmc.org/xbmc-13-0-gotham-rises/

The latest version of XBMC is here, and it includes improvements in efficiency on Raspberry Pi:

Since the release of Frodo a lot of effort has been put into getting XBMC to run smoother on lower powered platform like the famous Raspberry Pi and of course Android. All this effort has paid off and the experience of using these devices has become much more polished and satisfying than ever before. In particular, opening your libraries, browsing through them, loading images and starting videos have all seen dramatic speed increases

This is good news and has confirmed in my mind that putting Raspberry Pis in bedrooms to use as set top boxes is the right choice.

XBMC 13.0 and Mythbuntu 14.04 working together will hopefully be a nice straightforward set up.

More soon...

The plan..

I've become unimpressed with the quality of pay TV, and find myself watching mainly free-to-air channels such as BBC, Channel 4 and Film 4. As a result I've decided to have broadband only and recycle an old desktop case I have lying around to build a media centre/HTPC for the living room, serving live and recorded TV and other media to 3 bedrooms.

The main goal is to try and keep the build cost of the living room backend server close to £700 (similar to the the annual cost of my current cable TV package and set top boxes), whilst striking a balance between power (for gaming), low noise and power efficiency as machine will be on 24/7. The bedroom PCs are to be less than £100 each, so probably Raspberry Pis running XMBC.

I'm looking forward to more geeking out on the research, build, and setting up of such a system.

So far, I have the following hardware connected to my living room TV:

• Case: ATX tower case, £0 (recycled)

• Storage: An old Western Digital SATA1 160 GB HDD, £0 (recycled)

• Motherboard: MSI 990FXA-GD65, £57.98

• CPU: AMD FX-6300 3.5GHz Socket AM3+, £80.99

• RAM: 8GB Kingston low-profile (so Scythe heatsink fits) RAM, £60

• PSU: Corsair CX600M, £52.96

• Graphics: MSI GeForce GTX 650 N650-1GD5/OCV1, £51.98

• CPU Cooling: Scythe Mugen IV, £37.11

This is a working system, but not the final build. I am outstanding a TV tuner to be able to receive Freeview broadcasts, SSD on which to install the OS (Ubuntu) and Steam files to ensure system is spritely, larger HDD to store media (music, films, TV), and some peripherals such as a wireless keyboard.

• TV Tuner: TBS 6285 T2 PCIe card, £125.00

• SSD: Crucial M550 250GB, £107.94

• HDD: WD Caviar Green 2TB, £65.00

• Wireless Keyboard: Logitech K400, £29

Total price should be not far off £668.00

In it's current form (i.e. without SSD) Ubuntu and Steam are rapid, even with the motherboard set to ECO mode.

The Scythe Mugen IV was money well spent, as it is virtually silent - the noise that the stock AMD cooler made was really loud!

The machine now emits just a low hum, which is imperceptible when sat more than a few feet away from the case.

I should be in receipt of my TBS 6285 tuner card very soon; once I have I will post a progress update on setting up MythTV as a backend and XBMC as a frontend.
