Thanks for the new version.

So I just installed OpenPLi develop (2022-04-23-develop) / openpli-develop-gbquad4k-20220425_usb.zip on my other Gigablue UHD Quad 4K.

Bug is still present in this nighty build, even with

config.usage.http_startdelay=2000

With enigma2-plugin-systemplugins-forceFbcLNBpower_1.0_all.ipk installed and

config.plugins.miscControl.forceLnbPower=on

everything works flawlessly.

WanWizard, thinking about your question how exactly I should record got me to another idea unrelated to recording I haven't had before, so thanks for that :-)

I tried the following in the last hour (of course with Force LNB Power off, receiver in standby, no recordings):

Streaming Das Erste HD (19.2E, Tuner I) on two streaming devices. Then switching to BBC Two HD (28.2E, Tuner A) on just one of the two streaming devices (the other one stays on Das Erste HD):

Result: The bug doesn't occur!

(Just to double check I haven't changed anything else, I stopped one of the two streaming devices afterwards and switched between the two channels on the other streaming device: Streaming switching to BBC Two HD (28.2E, TunerA) I immediately ran into the known bug.)

So,"Force LNB Power: Yes",solves your problems?

On OpenATV with

config.tunermisc.forceLnbPower=True

and on TeamBlue and OpenPli with your

enigma2-plugin-systemplugins-forceFbcLNBpower_1.0_all.ipk

plugin installed and enabled every switching under any circumstances works absolutely reliable. This is true for my minimal testing configuration, as well as my usual 12 satellites configuration.

So, for me this is a very good bug workaround I am happy to life with in the long term.

At the same time I do think, that my setup (GB UHD Quad 4k with additional Dual Multistream tuners) and a Technisat 17/8 multiswitch is neither a popular, nor a very rare setup.

The situations this bug occurs (during standby without recordings: Switching between streaming from additional tuner channel to streaming from fixed tuner channel AND even just in maybe on one of four tries) are so special that I guess this bug is probably present in a lot of configurations without ever getting identified.

With streaming from E2 boxes getting more common these days I think the bug should be addressed. The fact that it happens during streaming, but not live tv is what makes this bug nasty.

So if any developer wants this box or just the additional tuner for testing feel free to send me a message, so I can send the box/tuner via mail.

Fine tuning DiSEqC install plugin SatelliteEquipmentControl.

 

Thank you. I will take a look at it.



All Measurements on OpenATV 7.0.20220419 (2022-04-18) without the enigma2-plugin-systemplugins-forceFbcLNBpower_1.0_all.ipk, but with OpenATV Force LNB Power option set to No (or to Yes later).

- Force LNB Power: No



- Live-TV:
   

Das Erste HD on Tuner I. Voltage on Tuner A: 0 V

BBC Two HD on Tuner A, Voltage: 13.5 V continously lasting.


---


Standby, no Live-TV:

Streaming Das Erste HD on Tuner I. Voltage on Tuner A: 0 V


Streaming BBC Two HD on Tuner A. Voltage on Tuner A: 13.5 V, drops off after some seconds to 0 V.


Non-working Stream BBC Two HD on Tuner A. Voltage on Tuner A: 0 V - when should I measure the voltage? After the moment DreamPlayer throws an error it is 0 V. I don't know about the time before, because how can I know it will work or not? Maybe I could switch streaming from Das Erste HD to BBC Two HD very often and observe the voltage from the beginning - but I haven't done this so far.


Additional test: Streaming Das Erste HD on Tuner I. Voltage on Tuner I is 13.1 V, after some seconds it drops to 0 V.


------------------------------------------------------


Force LNB Power: Yes


- Live-TV:
   

Das Erste HD on Tuner I. Voltage on Tuner A: 13.5 V continously lasting, even when the STB goes to standby.

BBC Two HD on Tuner A, Voltage: 13.5 V continously lasting.

Standby, no Live-TV:


Streaming Das Erste HD on Tuner I. Voltage on Tuner A: 13.5 V


Streaming BBC Two HD on Tuner A. Voltage on Tuner A: 13.5 V continously lasting.

I just connected the Tuner I directly to Horizontal-Low cable of the Quattro-LNB (to receive Das Erste HD on Astra 19.2E) and Tuner A directly to the Vertical-Low cable of the Quattro LNB (to receivee BBC Two HD on Astra 28.2E).

Even with

config.tunermisc.forceLnbPower=False

the streaming switching between the two channels works reliable this way. So I guess the bug might have to do with DiSEqC switching timings.

I will report back the multimeter measurements soon.
