How to update CrazyCat driver package

Hauke · September 28, 2018 at 9:04 PM

Dear all,

is there a comprehensive guide how to update the CrazyCat TBS drivers? I am using

@kszaq's image for amlogic (on Le Potato)
a WinTV Hauppauge dualHD DVB-T2 USB stick,
The CrazyCat TBS drivers
TVheadend 4.3

and both tuners are properly recognized, but Tuner #1 works nearly fine (once in a while a continuity error) while Tuner #2 only gives jerky video and loads of continuity errors. I seem to understand that the drivers have improved, but for all Googling I seem to be to stupid to get a up-to-date package. Can you help me?

Side remark: Yes, I am aware of CoreELEC and of the experimental support of Le Potato in the official LibreELEC build, but CoreELEC has very old CrazyCat drivers (by design/on purpose) and only TVheadend 4.2, and the official does not even recognize my TV card and also only has TVheadend 4.2. For DVB-T2 I need TVheadend 4.3, which luckily is in kszaq's image.

Thanks for help!

that is sadly not easily possible, I try to add an recent version to one of the next LE9 releases

Hauke · October 1, 2018 at 9:45 PM

OK, understood. Thanks for taking care with the next release!

Having similar issues: Still lots of continuity errors. Signal strength and SNR both good.

I went from CrazyCat's 8 builds to the Alpha because of this.

CvH just realized that you did the Crazy cat builds.

I've read the DVB issue since LE switched to kernel 4.9.x post, and am having the continuity errors.

Could you update the build with the 8.2.3/4.8 kernel?

Your DVB card is not affected by that problem.

this are mostly bogus values, don't trust them !! (maybe they are correct for that card, I don't know).

for that card you might test the DVB latest drivers from LE9 btw the default ones if they make anything different

Hauke · November 14, 2018 at 10:32 AM

Hi CvH,

I've just seen that the new release is there, and that CrazyCat drivers are in there in the newest version. Thanks a lot for that! Just tested on Le Potato: It is certainly the best experience I yet had with Kodi on LePotato regarding the Hauppauge DualHD card, but it is still not good. When watching a second channel, I still get too many errors to call the experience enjoyable.

In the meanwhile I tested with Raspberry Pi and the 4.18 kernel, since Hauppauge claims native support for the dualHD stick starting with kernel 4.17, and I can confirm that the DVB-T2 reception is flawless with 4.18, even watching two channels simultaneaously. Raspberry, even 3B+, ist not powerful enough to watch even a single channel in HEVC (German DVB-T2 uses it), but using TVheadend on Raspberry and a Windows machine to watch the channels works totally fine.

So, I suppose I need to stay patient until LibreELEC on Le Potato is on mainline kernel... According to a tweet by the Le Potato team, they already did a showcase with LibreELEC and mainline recently, so it seems to be close to reality anyhow...

I really appreciate your efforts! Thanks again!

One of the current gaps on mainline code is software-only deinterlacing. It's watchable for most programming but sports with lots of fast panning shots have bad combing. I keep a spare box on 8.2.5 for watching F1 and MotoGP coverage

Hauke · November 14, 2018 at 6:09 PM

Is there still much interlaced content? Interlacing in my mind is something outdated from SD TV times, when technology was just not fit for full pictures... But I stand to be corrected.

Whatever - what I am currently thinking about is just letting run my Raspberry in parallel to Le Potato and point the PVR frontend to the TVheadend on Raspberry with kernel 4.18. Not my long term solution, since it eats up another 5W of standby power, but until Le Potato is fit, it might be a solution.

**chewitt** · November 15, 2018 at 7:03 AM Official Post

It rather depends on where you are in the world. In a number of EU countries there are popular satellite and terrestrial broadcast channels (even HD ones) that use interlacing so it's important for people using Kodi's DVB capabilities.

Using an RPi as the back-end should be fine.

Hauke · January 6, 2019 at 2:21 PM

Hi guys,

just updated to LibreELEC (Leia) v8.95.2 BETA on my Potato - and lo and behold! - despite still having kernel 3.14, both tuners of the WinTV dualHD work flawlessly! Not sure what you changed, but it did the trick. Thanks a lot!

Cheers

b_ignatov · January 8, 2019 at 9:13 AM

Good to see that official LE builds support DVB drivers. Thanks for your great work and support.

Hauke · January 8, 2019 at 8:11 PM

Sorry to say, but I was a bit too fast with my assessment. It is *nearly* flawless. The continuity errors on receiver 2 are gone, but funny as it is, now receiver 1 has occasional continuity errors, but very few. Changed the receiver priority in tvheadend so that receiver 2 is default - fine for the moment. Seems I have to wait for mainline kernel after all

b_ignatov · January 11, 2019 at 8:42 AM

I think this little bug will be cleared in the next official release and I hope, because I ordered the same Hauppauge tuner

Hauke · January 11, 2019 at 6:29 PM

Well, even if the bug is not fixed, do not despair: The mainline kernel is around the corner also for Le Potato, and then all problems should be gone. I think only very few devices still use the 3.x kernel, and if you do not own such a device, you're safe now.

b_ignatov · January 11, 2019 at 9:17 PM

I'm going to use this tuner on my Wetek Hub with some of the official releases of Libreelec.

Did you try the newest LibreELEC (Leia) v8.95.2 BETA?
