Remote control issues in Live-TV

lucker10 · November 25, 2020 at 6:25 PM

Hello,

first I want to thank you for your amazing work - Having a full media center on a single 5W raspberry pi is just awesome. I'm using Libreelec since 5 years now on a raspberry pi 3 and it's still running smooth, handling live-tv, recordings and so on.

But, there is one problem I have on Live-TV. As soon as I select a channel and play, most button presses of my remote control are lost. I have to press each button a few times, before it is randomly recognized. I'm using a IR receiver on the GPIO pins. For TV, I use TVHeadend. I remember that I had this problem in the past with former versions as well.

Is this a known issue? Any idea how to start debugging?

Thanks in advance!

This is a well known issue, see here Infra-Red Remotes - LibreELEC.wiki

so long,

Argh.. well, thanks for that information. That means that a USB IR receiver would not have these problems?

Yes, that should work fine. An MCE USB receiver (the HP branded ones you can find cheaply on ebay work very well) or switching to an RPi4 (which uses a "real" USB controller) are other alternatives to the ones mentioned on the wiki.

so long,

Indeed, using a USB IR receiver (in my case Y.A.R.D.2 mini with RTC) solves the issue, it's running perfectly now.

Just FYI - on RPi 4B due to much better hardware this issue does not exist anymore, IR works fine on GPIO with LE regardless of USB data transfers.

Regarding to RPi 0-3 I think IR remote controls based on RC5/RC6 protocol could work even through GPIO receiver during long USB transfers but it might not be easy to discover the protocol type at first sight so the supported USB IR receiver is the best choice.
