Hardware decoding (with licenses) will still work on RPi2/3.

Major issues on RPi2/3 are that the video driver currently has a severe problem (video cuts out and needs reboot), GPU accelerated HEVC decoding and deinterlacing doesn't work (deinterlacing also doesn't work on RPi4).

Therefore we decided to do the initial LE10 releases only for RPi4 - RPi2 will follow later, when the major bugs are ironed out.

so long,

Hias

Thanks for quick info..I asked as I v seen a post elsewhere that has nothing to do with LE, which made me wonder:

There is no support for hardware accelerated VC-1 or MPEG2 on Raspberry Pi, even on existing devices where codec packs have been purchased.

There is also no deinterlacing for Live TV with hardware acceleration on Raspberry Pi, but we are hoping that support is introduced later at some point with a Kodi 19 point release. This should be less of an issue on Raspberry Pi 4, which should be able to handle deinterlacing in software.

Did I Understand properly regarding hardware decoding on RPi 2 that mpeg2 video won't work anymore with rpi licences but is done via software?

Main issue is will live Tv be affected?

Quote from CvH

Due the lack of further developement at Tvheadend I have no idea what future brings.

Hi CVH.

What you mean by lack of further development?

Is that bad news?

try copy and paste this exactly..

below is yours...you moved few bits:

os.system ("echo" Raspberry Pi Shutdown! "> / dev / pts / 1")

It worked here...no reason it doesn't work for you...you can open more terminal windows to test from one to the other and you ll see the message popping up..

I m not great with python hence i gave you the shell version of the command..you r basically sending an sh command from a py script..

I m not sure what your script is for but if it's something important you can even send an automated email from libreelec to your email..

Quote from aldebaranhg

the problem was definitely autostart.sh

I logged in with a terminal program (mobaxterm) and the /storage/.config/autostart.sh file was just one line
python /storage/.kodi/userdata/scripts/powershutdown_serialless.py &

created and the rights set with chmod.
the command is now executed correctly. after entering ps -ef i can also see the running process. 566 root 0:00 python /storage/.kodi/userdata/scripts/powershutdown_serialless.py

it would be nice if a message could be sent to all logged-in terminals in the event of a power failure - is that possible?

the print commands from the powershutdown_serialless.py script do not arrive on a logged-in terminal

Many Thanks

try before line 50 in your script add

os.system("echo "Raspberry Pi Shutdown!" >/dev/pts/1") 

that is for 1 open terminal

if you have more then

to find all open terminals

find /dev/pts

then you can edit your script ex

os.system("echo "Raspberry Pi Shutdown!" >/dev/pts/1")
os.system("echo "Raspberry Pi Shutdown!" >/dev/pts/2")
os.system("echo "Raspberry Pi Shutdown!" >/dev/pts/3")

etc

that should send a message to all terminals

"Raspberry Pi Shutdown!"

Check your autostart.sh script if you just created it for any errors DOS format and not UNIX?

this should start your script like on startup..

sh /storage/.config/autostart.sh

run this on autostart.sh

dos2unix /storage/.config/autostart.sh

chmod 777 /storage/.config/autostart.sh

the autostart.sh in your zip file is in windows dos...needs to be unix format..but might have changed by uploading or downloading or whatever..not sure...try those 2 commands and you should be good to go..

Quote from Grarea

I just had a thought.
A faulty usb to sata adapter couldn't short something in the pi and make HDMI audio not work could it?

I have that, plus also that ssd fail, plus my spdif card on my pc seems faulty now as well.

Plus I tried to charge my torch up from my pc and that won't charge from anything now.

I am wondering if i have a fault somewhere.

I can't think of anything other than the adapter and ssd that are common between my pc and pi.

I had a cable like that for a long time connected to my pi2 and hdd never gave me problems...Now I got an external hdd connected which is a little better aesthetically but nothing else..

Maybe some power issue?

What power adaptor are you using?

Quote from ninjaw

Did you manage to fix the blinking Led on your script?

edit your script

import time

from top of script

and replace with

import time
from time import sleep

then wherever you have

time.sleep

replace with

sleep

Been testing bits from that script as I m trying to make a script for myself with 1 button that blinks led and it worked that way..

Quote from Nayed

If I want just to start rpi only do I need to add the dtoverlay=gpio-shutdown to config.txt. and 1 maybe stupid question - where is this config.txt file on pri4

To power up, all that’s required is to connect physical pin 5 (BCM 3) to the ground next to it. This functionality is enabled by default.

To shut down with the same button, just add the line dtoverlay=gpio-shutdown to /flash/config.txt

config.txt is read only

to edit ssh

mount -o remount,rw /flash

then to make it read only again

mount -o remount,ro /flash

Quote from Nayed

True for the reboot and shutdown. In fact I am using the Kodi app on the phone as a remote control but for the activation I can not use it

So you said just shorting pin 5 and 6 will start rpi( you mean GPIO3 and GND)??? Directly shorting them with nothing else?

Yeah thats what I mean gpio3 and the gnd across it...you add dtoverlay=gpio-shutdown to config.txt..

Quote from Nayed

Mario77, Da Flex,

Your explanations are very useful. I was thinking to implement such a button on my Pi4 BUT I was thinking... What if the power button is with IR for the regular TV or Bluetooth from the phone. Is this possible to be done? I think this will be just a bit better for usage

Thanks again for your explanations!

That will be usefull just for startup if it works...basically reboot and shut down are the same as the ones you r using now from Kodi power menu..so you can set the remote buttons even without switch..

Just a quick idea is a transistor between pin 5 and 6 and an ir receiver connected to it...basically if you short pin 5 and 6 rpi will start.

You just edit script and restart to try with 50% to 100% but you dont really have to..if fan is working all should be fine

If you want to try change values just ssh systemctl reload fan.service or stop and then start service

Quote from Nayed

Thank you!

speed steps in script are low so you dont see much difference by looking at the fan

tempSteps = [30, 35, 40, 45, 50, 55, 60, 65, 70, 75]  # [°C]
speedSteps = [0, 35, 45, 50, 55, 60, 70, 80, 90, 100]  # [%]

try to change the steps and you ll see a big jump from 50% to 100%

something like:

tempSteps = [45, 50]  # [°C]
speedSteps = [50, 100]  # [%]

This way it jumps from 50% straight to full throttle

Quote from Nayed

How can I verify that the speed fan is temperature controlled? I am looking at it and speed seems the same all the time

Post #74 I posted a small script calibrate.py

That is similar script to the one on #60 but works manually from terminal instead of reading temperatures...it's just for testing and to find your fan minimum speed...mine started at 30%...less then that and it wont turn...

You can test fan with that script from terminal....you type 50 will be 50% speed..100 will be 100% speed and so on...

2 pin 5v fan

I made a circuit with 2n2222 transistor and 1k resistor I use the following circuit

Temperature Controlled Fan for Raspberry Pi 4 - Fizzy

but I would like to use your script from #60 because of the speed control

I just change the fan file from the link above with your script from #60 and now intend to turn it on

Seems I made something wrong(either circuit, either places for the script, .. or something else) as I turn it on but the fans are not starting

Did you connect transistor base to the proper gpio?

Quote from Nayed

I have a great request:

Can you sum up 1 working solutions with all the steps needed in your first post as the topic is interesting but it is going longer and longer.

The topic is growing and in 1 part we have scripts, update in another, after there is script with variable speed and for me it is a bit confusing

Thanks in advance!

What are you planning to do?

2 pin 5v fan ?

Script in post #60 works fine for PWM temp/speed control..

You just need to make circuit..

Well although power button works as intended..unfortunately it doesn't work if system is for some reason frozen..so it might still need a dirty power shutdown once in a while..
