EDIT by wrxtasy..

Sorry @best_odroidfreak, I've had to commandeer your post to compile a master list of working USB DVB TV Tuners:

Confirmed working USB tuners - Kodi PVR backend servers:

- Sundtek SkyTV Ultimate (DVB-S/S2) Stick
- DVBSky S960 + Mygica T230 + Tvheadend 4.1.1945
- DVBSky T330 works together with Sundtec MediaTV Pro III
- Edision Optimuss DVB-C/T/T2 USB Tuner Combo Stick (DVBSky T 330 compatible)

wrxtasy · Post by **wrxtasy** » Tue Aug 02, 2016 12:47 pm

@aNORes,
Nice work indeed !
That will make a LOT of USB DVB users very happy as they can now use modern Tuners with the older v3.14 Linux C2 Kernel.

Suggestion
Can you rename the .img and .tar files to end with -media_build.tar -media_build.img so as to not confuse users with the number of LE editions floating about ?

andy5macht · Post by **andy5macht** » Tue Aug 02, 2016 5:04 pm

wow this sounds really nice. thanks for the nice work!
i am going to try DVBSky T330 later today.

The file names changed, I added also md5sums.

@aNORes,

Please reconfigure the lirc.conf and recompile as you have broken lirc and IR with the changes you currently have in this LE media_build
Revert to this original CONFIG_IR section for linux.conf and lirc will work again.

andy5macht · Post by **andy5macht** » Wed Aug 03, 2016 6:18 am

my DVBSky T330 works together with Sundtec MediaTV Pro III without external power. thanky you so much!
amazing fast channel switching!

Record two channels at same time. nice nice nice

Great news!

Is there any working ATSC USB receiver for US and Korean people?

wrxtasy · Post by **wrxtasy** » Wed Aug 03, 2016 1:47 pm

The HK guys must have a bunch or USB DVB dongles available for testing, and then it would help end LE C2 users if we compile a master list of working dongles here.

I will keep this master list in one of the first posts to ease the burden of searching through this thread

I am an HK guy obviously

but we have no USB TV receiver dongle at all.
I tried to find one. KWorld UB435-Q or Hauppauge WinTV-HVR-955Q seems to support linux driver. But they are expensive probably.
I will try to search other models.

Raybuntu · Post by **Raybuntu** » Wed Aug 03, 2016 8:27 pm

I hear the sundtek devices work very nice. They are precompiled (closed source) and arch independent and run on basically everything. They cost a bit but you get a working usb DVB device.

Post by **odroid** » Wed Aug 03, 2016 9:00 pm

I'm quite new in this area.
Is the DVB-C/T/T2 are compatible with ATSC FHD in US/Korea?
Sorry for hijacking. Would be better to make a new thread...

Raybuntu · Post by **Raybuntu** » Wed Aug 03, 2016 9:11 pm

@odroid: I think DVB and ATSC are 2 different standards and they are not compatible. But hey the new Amlogic S905d is suppose to have a DVB interface. Maybe something for a new Odroid C3

*HINT*

EDIT: @odroid Look here: http://sundtek.com/shop/Digital-TV-Stic ... logTV.html
It's a ATSC stick that should work.

I would be interested to see how this media-backports release goes.
Its a bit different to aNORes's media-build as a whole bunch of driver modules are backported from the v4.7 Linux Kernel.

http://forum.odroid.com/viewtopic.php?f ... 50#p155665

I can revert individual modules as well to use the original HK v3.14 Linux ones.

i tried this.
no more continuity errors with this release on T330 tuner for about an hour.
i will let it run for the next 9 hours - so we will see.

@aNORes: How did you disable cec? In the kernel config? Normally disabling cec with hdmitx=cec0 should do the same. Trying to figure out how this is possible. I'm using vdr and I have no issues. Are you guys using emmc or microsd. Is tvheadend caching on disk? Maybe the cec logging is causing the issue.

andy5macht · Post by **andy5macht** » Tue Aug 16, 2016 4:19 pm

i am using a 8gb emmc module.
tvheadend caching?: what does that mean - picon image caching? i am using timeshift "fit to ram only"

Yes.

Raybuntu wrote:Normally disabling cec with hdmitx=cec0 should do the same.

It does not work. I disabled both in the Kodi CEC adapter and boot.ini.
I also tried your patch: https://github.com/Raybuntu/linux/commi ... 675c6cdb59
Still get "Continuity counter error"

Raybuntu wrote:I'm using vdr and I have no issues.

I also tried VDR. VDR does not show any error (debug in VDR is enable) but I see the picture micro stutter when I watch live TV. @Raybuntu try Tvheadend.

My kernel config:

Code: Select all

Device Drivers  --->
 Amlogic Device Drivers  --->
  AO CEC Support  --->
   HDMI AO cec driver support = no

"Continuity counter error" still exist
strange... but also with ...

Code: Select all

Device Drivers  --->
 Amlogic Device Drivers  --->
  HDMI TX Support  --->
   HDMI new CEC driver = yes

"Continuity counter error" completely gone

...and sorry for my English, I write everything via translator...

Raybuntu · Post by **Raybuntu** » Tue Aug 16, 2016 7:52 pm

@aNORes: No problem with the language. I'd still like to solve this. I still can't imagine how a cec driver is causing issues in TVheadend. Is that for every DVB card or just a few?
Also let me get that straight. If you disable AO_CEC from kernel config you still have the issue? It's only gone when you enable "HDMI new CEC driver"? That's even stranger.

Can you try to give me more info what that tvheadend error means?

Raybuntu · Post by **Raybuntu** » Tue Aug 16, 2016 10:48 pm

@aNORes: Can you confirm that the issue is still there if you use libcec and not the internal CEC keyboard mode? The log you supplied was with AML cec keyboard mode and I copied the code from the old driver. Especially this:

https://github.com/Raybuntu/linux/blob/ ... cec.c#L193

There is a HR_timer that might be causing your issues. Can you please confirm that using AO_CEC with only libcec does not cause the issue on key presses?

wrxtasy · Post by **wrxtasy** » Tue Aug 16, 2016 10:56 pm

@ aNORes, is it possible for you to Fork my LE 7.1 on Github and then push your own changes to your own Repo so we can all see what is going on ?

I've just updated my LE7.1 with some patches changed, also the important ao_cec disable one from Raybuntu to disable CEC completely.

Yes, but a little later, a lot of things I still "do manually."

Raybuntu · Post by **Raybuntu** » Wed Aug 17, 2016 1:10 am

Enable libcec in kodi's peripherals settings. The log in the CEC thread indicates that you use AML CEC keyboard mode.

BTW. Thank you for reporting and helping to solve this.

crashoverride · Post by **crashoverride** » Wed Aug 17, 2016 1:46 am

A discontinuity error in TVheadend means the MPEG-TS stream lost a packet in transit. The two typical causes of this I have seen are 1) poor signal quality and 2) USB subsystem latency.

DVB cards typically have a USB BULK-IN endpoint that provides the raw MPEG-TS data stream from the demodulator. This is real time data. On devices with the dwc_otg USB controller chip and driver, this generates an insane amount of interrupts that need to be handled (every 512 bytes). Having any USB 1.x (keyboard/mouse) devices on the same hub compounds this problem causing split transactions that require even more IRQ time.

If the CEC driver is also doing "real time" work, it may be causing IRQ handler delays. A possible solution would be to "pin" (IRQ affinity) each driver's IRQ to a different core. Another suggestion is to plug the USB tuner as the sole device directly to the USB-OTG port eliminating any hubs.

Raybuntu · Post by **Raybuntu** » Wed Aug 17, 2016 2:05 am

Thanks crashoverride. We already looked for irq handler delays but there is nothing obvious I can find. However there is a HR_Timer for the input_events that are beeing faked by the Amlogic driver to produce keyboard events. I suspect this is causing problems because he's having the issues even if he disables the ao_cec driver and reverts to the old cec driver where I copied the code from.

I've tried, does not help.

I guess I don't know then anymore. Disabling CEC should have worked. There shouldn't be any interrupts if you disable it.

crashoverride · Post by **crashoverride** » Wed Aug 17, 2016 3:54 am

Its also possible that tvheadend is holding on to the URB "too long" and the combination of everything pushes the deadline over the mark. Testing with some other dvb client program should be done; however, I do not know which one would be a good choice because others will stutter on software video decoding and also will not report the dropped packet.

@aNORes: can you try what crashoverride suggested and change the smp_affinity of CEC irq just for testing:

echo 2 > /proc/irq/231/smp_affinity

cat /proc/interrupts will give you a list of interrupts and on what CPU.

Hmm...It looks like that is well...I'll do the tests at night...

Now I need to find the delay in the isr handler. It's not that obvious but gdachs Amlogic CEC driver doesn't have those delays. But it's probably a good idea to use some kind of irq balance.

@aNORes: any news did the command help? Can we recommend the settings for users in autostart.sh?

Raybuntu wrote:Can we recommend the settings for users in autostart.sh?

Yes, this setting is strongly recommended:

Code: Select all

echo 2 > /proc/irq/231/smp_affinity

Sometimes I still have error "Continuity counter error" but it may be accidental (signal quality?) and independent of CEC.
I have to do more tests.

Rock stable, no errors (accidentally?) "Continuity counter error" with the kernel settings:

Code: Select all

Odroid:~ # zcat /proc/config.gz | grep -i cec
# AO CEC Support
# CONFIG_AML_AO_CEC is not set
CONFIG_AML_HDMI_TX_NEW_CEC_DRIVER=y
Odroid:~ #

Tomorrow I will compile the "hybrid, all-in-one" build (media_build, ljalves, crazycat, backports drivers) so everyone will be able to choose what suits him best.

noREs, I'm sure you are aware LE is Open Source software.
Make sure you publish your LE modifications to GitHub or similar to comply with the GPL licences the LE and Kodi code contains.

Both RB and I can help if you run into publishing issues.

In a nutshell:

Compile - LibreELEC
Compile - media_build http://forum.odroid.com/viewtopic.php?f=136&t=20302
then repack SYSTEM image (mount -t squashfs -o loop..., mksquashfs...) https://sites.google.com/site/andreierd ... shfs-howto

Of course I can describe it very exactly. I'm not a programmer. I do not know how git works (I know only: git clone + that I find in google).
If this method violates the GPL license - then I stop to publish my builds.

Raybuntu · Post by **Raybuntu** » Sat Aug 20, 2016 11:59 pm

I guess noone wants that. We highly appreciate your builds.
GPL dictates if you publish binaries you need to publish the sources too but on your terms. So you could just point to the sources from others if you haven't done any changes and publish your patches somewhere. Thats for the legal part but noone forces you to do anything.

I personally appreciate your findings about that CEC irq issue.
Its ok if you are no programmer we don't judge. For what it's worth your builds seem to work for users. However if you are interested to collaborate we are happy to explain stuff.

Thats just an offer. I remember wrxtasy had some trouble publishing his sources at first too

Ok,

I'll try to learn git -> push my modifications -> publish my builds

Yes I did and I'm still learning. So I don't like to throw stones at LE users doing good work like aNORes.
Devs. understand the steep Git learning curve initial required so have to be patient too.

Once you learn a bit about Git and Open Source code and see where your Open Source version of a project ends up it becomes pretty satisfying, especially the collaborative effort that goes into a big project like LE Kodi.

@aNORes, I understand now what you are doing and yours really is a very custom Linux LE job, especially as you are manipulating images directly. If it works, that is all end users really care about. Publishing can stay on the back burner as it looks a bit difficult anyway.
Keep up the good work

Is this build supposed to be better/faster than wrxtasy's for Kodi usage?

No, only support dvb cards.
