Replacement for old mini PC to support 4k...

    Hi there, until now I have a pretty old mini-PC running with latest LE ...

    As I am getting a 4k screen soon and also have some movies in 4k, I was thinking to replace that old mini PC as trying to play a 4k movie resulted in stuttering video.

    Any on t expensive recommended hardware? I have some mainboards and i7 CPUs laying around, but they either are lacking Toslink audio output or actually are too old to support 4k on HDMI output by mainboard limitation.

    What are current recommendations?

    If possible I would migrate the SSD from the current machine to save the trouble of setting all up again.


    Thanks

    RPi4 is great but the speed difference between RPi4 and RPi5 is noticeable (once you compare them you won't want an RPi4). Sell the pile of old stuff on eBay to fund an RPi5 + NVME HAT.

    Maybe a stupid question: how do you start the RPi aftet shutting it down?

    The concept is to connect two pins temporary. So it would be useful to buy a case with a push button.

    RPi4 GPIO using in LibreELEC

    Dear All,

    Is it possible use GPIO pins with LibreELEC on RPi4? My idea is use some GPIO pin for LED in the power button for signaling that system is running. Now I´m using only standard shut down funtion in Kodi and RPi4 weak-up function with button on GPIO pins 5 and 6 made by this manual:

    How to Add a Power Button to Your Raspberry Pi - howchoo

    All manuals I found for this is for NOOBS but not for LibreELEC

    Thanks

    142€ for a kit with cooler PSU etc is not too bad for the 8GB version I guess?

    8GB is a bit overkill 4GB will do just fine, probably even the 2GB.

    2GB runs fine for a simple playback client device. If you want to run a load of container/server services in the background then 4GB or perhaps 8GB will be more suitable.

    Thanks for the feedback. It will be only playback device. I have a Proxmox server running all other things needed 👍😅

    So 2 or 4 GB depending on a good offer I might find. Case with button sounds nice. Thanks!

    One more question here:

    My current 5.1 surround system has optic audio input.

    How would one get proper surround sound from the RPi4 (I found one almost free :D )

    Sorry for noob questions, my main use of RPi for now is headless devices like for ADSB tracking etc

    My setup is RPi --HDMI--> TV --TOSLINK--> AVR.

    If your TV has no TOSLINK output, buy an HDMI audio extractor. You can use the second RPi4 HDMI output (HDMI-1) for that.

    it's also depending on the theme for kodi, classic theme, 2GB is enough, but more eye candy theme need more ram


    my setup is RPi4 4Go (next replaced by Rpi5 8Go) ---hdmi passtrough---> AVR -> TV

    There are also lots of inexpensive audio HAT devices that will give you an S/PDIF output direct from the RPi to AVR.

    Found HiFiBerry Digi+ Standard Version for 45€ shipping included, so probably gonna buy that one :)

    A button to shorten 2 pins for power on should be easy enough to find, so that might work then. Thanks and nice week people!

    So all seems fine :)

    Except the 4k video that stutters.

    Might actually be the 2GB version that is too low specced?


    Idea: RPi 5 with 8GB (~85€) - Raspberry Pi M.2 HAT+ (~15€) - some old NVMe SSD I find in the office cabinet...

    Should give much better performance disk-wise and maybe also helps with the issue of the 4K decoding?
