Sooo, I am now running the Odroid N2+ with 2 GB and my H265/4k/HDR/Atmos videos are finally playing as smoothly as they should. This thing is a beast with 50% more power in the CPU Benchmark add-on, and I guess the whole hardware is just way more powerful.

As suggested by chewitt I also tried overclocking the Pi 4 according to https://forum.libreelec.tv since I am running it in their great passively cooled case:

• arm_freq=1950
• gpu_freq=650
• over_voltage=5

But it did not help with the stuttering.

Since LibreELEC is only in alpha stadium for the Odroid and does not play those H265 videos at all for me, I switched to CoreELEC, which is identical and running perfectly so far.

So it could also be that CoreELEC has a "better" or just different (since it's a different SoC) implementation of decoding high-end H265 files?

But I guess I am in the wrong forum from now on.

Just wanted to let everyone know who are still looking for the "right box" to play videos like those mentioned.

Thanks for the hints regarding network performance.

But even if I play from my external harddrive, where streaming high bitrates is not a problem, I still get microstutters playing 4k+HDR files with Atmos. Since everything else is playing smoothly, I can only think of the SoC being the bottleneck and was wondering if you know about the Pi's limits regarding playback. It sould not be a software problem, right?

I should try and play 4k+Atmos files with lower bitrates to verify that, but I don't think it's the bitrate but processing 4k+HDR+Atmos at the same time.

Hi,

I'm new to the forum but have happily owned a Pi 4 with LE for over a year now.

Now that I have more and more movies in x265/4K/24p/HDR/Atmos AND about 80 GB in size it has become hard to watch them since I get micro stutters. I am playing my movies from an external USB 3.2 harddrive (130 MB/s).

Movies with DTS are still playing fine. Or when I switch a movie with both Atmos and DTS audio tracks to DTS it's also working fine, but Atmos combined with those high bitrates seems to be too much for the Pi's hardware, I guess?

In addition, I finally switched to a Synology NAS which, of course, makes it even worse. Wifi hardware is pretty crappy on the Pi, I only get about 10 MB/s which is 80 Mbit/s, with my movies having about 65 Mbit/s. (On my laptop I almost always get 250 Mbit/s).

So my question is which alternative device would you suggest that can handle both 4k/Atmos videos properly AND has better Wifi hardware?

Would the Vero 4K+ be enough? It's chipset seems to be even weaker than the Pi's, but since it's all-in-one, it might be implemented better?

The ODROID-N2+ looks pretty strong and I obvisouly could run LE nightlies, which I would prefer over OSMC.

A NUC seems too expensive and too much hassle just for playing movies.

Thanks for any advice!
