There is an official PoE board that fits the pi 3+ which uses a 4 pin header by the ethernet jack to grab power. The pi 4 appears to have the same header. https://www.raspberrypi.org/products/poe-hat/

How is that Hat $20 when the entire board itself is only $35?

I also balked at the PoE Hat and ended up going with a $10 PoE splitter (with USB out). Works with any Pi (until this RPi4 with USB-C).

Oh my! This is such a crazy upgrade. I've been using the RPI2 as my HTPC/NAS at my folks, and I'm so happy with it. I was itching to get the last one for myself. USB 3.0! Gigabit Ethernet! WiFi 802.11ac, BT 5.0, 4GB RAM! 4K! $55 at most?! What the!? How the??! I know I'm not maintaining decorum at Hacker News, but I am SO mighty, MIGHTY excited! I'm setting up a VPN to hook this (when I get it) to my VPS and then do…

Even so, A72 is a highly-inefficient chip (which is probably why they set such a low clock speed for it). Cortex-A73 would've been much better. But I guess there always has to be at least one obvious lacking in Raspberry Pi generations.

I'm intrigued as to why they didn't use a big.LITTLE design (or whatever they're calling it these days). Perhaps mainstream-linux still isn't so great at handling it.

Do you have a good guide to setup a nice VPN server?

This script is really nice: https://github.com/Nyr/openvpn-install

It sets up systemd and iptables and generates all certs and keys and wraps them up into tidy, per-client .ovpn files

Really the only benefit of that is energy efficiency if it is used correctly, in exchange for additional cost or lower max performance. Makes sense for a smartphone, less so for a mains powered device (and the Raspberry Pi SoCs originally were designed for set-top boxes, although I don't know if that's still true for the new ones or if they're custom)

TLDR; of cons from various sources: - New SoC puts out more heat. Active cooling more important now. - Video playback at 4K requires H.265 - Micro-HDMI cables now needed. - Draws more power. Other than that, looks like a major performance boost.

>Video playback at 4K requires H.265

Not really a con IMO, I haven't seen anything on a 4k bluray encoded in h.264, everything seems to be 265. The microHDMI is kind of a bummer though.

I actually wonder if the A72 CPUs onboard are fast enough to do software h.264 4k decode. They might be.

It is, but in my experience the reliability factor is pretty ugly for the rpis. I'd rather either pay directly for the device designed for it, or just run the software on a machine already on the network. Obviously that doesn't work for everyone.

In my experience, anything other than the Cloud Key is quite unreliable. I have been running it on my Win10 desktop without many issues besides the annoyingly restarting after updating.

I run it on Server 2016, it's bulletproof there.

are you speaking about the pi 4 or 2? I just setup my RockPro64 with 4GB, also PCIex4, have an SSD, going to setup a raid at somepoint when I get it all figured out. The board was a bit more expensive than the pi4, but I am interested in playing around with it. But it looks like its back ordered for awhile

I did not get that board stable at all I’m afraid. Lots of issues with USB drives. https://github.com/ayufan-rock64/linux-build/issues/112

ahh, I started with a USB 3, removed it though and dropped in the SSD. So far so good, and using Dietpi, it works great (so far)

I imagine the wait must be agonizing! Why not just have a NFS server on your more powerful computer for the Pi to stream the file from? 100 Mbps is easily enough to stream any Bluray.

Not at all. The reason I upgraded my home LAN many years ago was exactly because 100Mbps is not enough to stream 1080p videos. It does suffice on average, but the bitrate changes a lot within the same file.

I haven't actually seen a single 1080p raw bluray file with a higher video bitrate than 35 Mbps. Maybe with TrueHD/Atmos audio the total bitrate could push past 40, but 100 Mbps is way more than you need for 1080p.

Even 4k doesn't seem to push past 50 Mbps, but I think that's because h.265/HEVC is more efficient for the same observed quality/CRF.

The addition of gigabit ethernet and USB 3.0 means that a Pi no longer feels like a bottleneck in one’s home network. I know that the Pi was invented as an educational product, but thanks to the Linux distribution OSMC it is commonly used as a media center for playing films, music, TV, etc. I have had gigabit internet for a few years now, and every day on average, I torrent a Blu-Ray image onto my main computer. Howe…

I just put together a Plex server with the RockPro64 4gb ram, PCI3x4 with 2 sata ports. I booted it up with Dietpi and things are running smooth! The board is a bit more expensive, but you can probably get it faster than the pi4 at the moment. The Dietpi community seems to be pretty great, any issues I ran into were answered pretty quickly

Are you running it as both NAS storage and a Plex server? How's transcode performance?

I put together a NAS/Plex box with a Kaby Lake Celeron and some hard drives, but I was thinking of splitting it out into separate NFS and Plex servers.
