Problems playing 4K HDR10 movies over SMB on Odroid N2+

Hello everyone,

I have an Odroid N2+ with 2 GB RAM running LibreELEC 21 Omega CoreELEC. I have the following problem: some 4K HDR10 movies (50 GB and larger) cannot be played over my SMB network.

I have already tested different configurations:

  • Odroid connected directly via LAN to a 4K TV

  • Odroid connected via a FritzBox repeater (LAN) to a 4K HDR10+ TV

  • All LAN cables are Gigabit capable

I also tried the following things:

  • Set the video cache to 800 MB

  • Using the Maintenance Addon from Peno64, I tested 400 MB and 1200 MB

  • The RAM usage does not seem to change much

  • I’m not sure if the current memory usage is displayed correctly

I have also reset everything related to network and power, but the problem still remains.

I’m wondering if there are other addons or settings that could help, for example using advancedsettings.xml to better configure the video cache or buffering.

I would be interested in an optimized configuration for the Odroid N2+ with 2 GB RAM, especially for playing large 4K HDR10 movies over SMB.

Does anyone have an idea what could be causing this? Could it be the network, the Odroid N2+, LibreELEC, the video cache settings, or the 4K HDR10 files themselves?

Thanks in advance for your help!

If anyone has the same Odroid, could you please check if you have the same issue with 4K HDR10 files over 50 GB? I’m trying to figure out whether this is normal or if it might be related to the RAM. The system only shows about 40% RAM usage, so I’m not sure if that reading is accurate.

There is also the Odroid N2+ with 4 GB of RAM — if anyone has that model, it would be great if you could test it as well and share your results.

Use CoreELEC-22, nothing else.

Just watching a 47GB MKV, 4k DV/HDR10 from SMB share, no issues.

If you really use LibreELEC it’s clear. It doesn’t support all video formats decoder in hardware.
Only h264, and there it’s also limited.

CoreELEC do support all video formats what the Amlogic SoC is capable of by using the hardware decoder.

I’ll try this out and get back to you shortly.

is this right ? CoreELEC-Amlogic-no.aarch64-22.0-Piers_alpha2-Odroid_N2.img.gz for Odroid N2+ 2GB RAM

Why does H.265 work then?

I’ll install this version now and then try the file again that was freezing or crashing.

So, I’ve installed the version now. The RAM usage is at about 50% (before it was around 40%). However, the video that was freezing before is still freezing. I should mention that it’s H.265, so as I said, it might be related to that.

If possible, should I download the H.264 HDR10+ version instead? Or do you have any other tips?
