Welcome to the LibraLit review of the Raspberry Pi 4B. On the left hand side here we have a 3B plus the outgoing device. On the right hand side we've got the new 4B. On the left the Raspberry Pi has a single full size HDMI connector, micro 8 USB power. You've got gigabit but attached to an internal USB bus ethernet and then two sets of USB 2.0 USB ports. On the Raspberry Pi 4B first we have a USB-C power cable that's providing 5V3M to the board. You have two micro HDMI connectors which support video output. LibraLit is only going to be supporting one of those at the current time because code only supports one of those outputting when running on the video stack that we run. On Raspberry you can run both screens at the same time. Turning the board around you've got two sets of USB ports, two USB 2.0 and two USB 3.0 which is going to give a nice boost to people streaming media off a hard disk. On the right you then have proper gigabit ethernet that is no longer attached to the internal USB bus. It's going to be a lot faster in the testing we've been doing. Media streaming off a NAS box and the network opens and starts playback with a lot more snap than it did previously. It's really nice to see. The board itself is shipping in three different RAM configurations, one GB which is maintaining the existing $35 in a original price point for the Raspberry Pi and then a 2GB 4GB version which are $45 and $55 respectively. Otherwise the board is pretty much the same as it was. The exception being of course everything's now a lot faster. The new Broadcom to PCM 2711 chip is using 4A72 cores whereas the previous board is using 4A53 cores. Although it's only a modest 0.1 gigahertz bump in clock speed it's actually a much larger bump in overall processing and media capabilities. The new board also has native support for HEVC so no longer CPU decoding that which is brilliant for code of use. Anyway let's move on to the next part of the review. We're going to add an SD card which is installed with Librelex new 9.2 beta one, sorry alpha one release we haven't got as far as the BTF. That can go into the microSD card slot whereas the Raspberry Pi is still using a microSD card. Some of the people out there might sniff and say it's not got EMC on it but microSD cards are perfectly fast enough for code of use. Librelex runs everything in memory anyway and performance is still very good. I'm going to add a float USB device because I want to be able to control it. Now let's move off to the TV. The review. Raspberry Pi is now booting up. This is the new Librelex 9.2 alpha one release. There's a small SPI bootflash on the Raspberry Pi 4 which will make future bootloader updates easier. Now we're in the Kodi home screen let's go review some system information quickly. First thing you'll notice is that there's three and a half gig of RAM free. That's because this is a 4 gig board and our testing we've also been looking at two gig and one gig configurations as well to make sure they run okay. For storage I'm just using a very basic kind of thing you buy in the supermarket SD card nothing fancy. The video driver is a new video called 3D driver because it's new. There are some glitches here and there. There's a little bit of screen tearing in some of the screen navigation. Some of the Kodi sort of transitions and file browsing views. Nothing major nothing that's going to ruin your experience and the Raspberry Pi foundation developers have been pushing updates at a phenomenal rate over the last couple of months as the boards been developed and things are a lot more stable now and I think the remaining glitches will be resolved fairly quickly. On the hardware you can see that the number of bogeomips is way up on what it used to be. The hardware is still reported as BCM2835 not the BCM2711 chip that's actually on the board that's done for software compatibility reasons it's the same in the previous Raspberry Pi 3 as well. Let's briefly look at some system settings. As you can see in the white list there's all of the 4K resolutions listed in addition to 1080p. I've got the resolution on this particular board set to 1080p it's not really necessary to run the entire Kodi UI 4K and it tends to make the UI a little bit faster and a little bit more responsive and that's not just true about the Raspberry Pi that's also true of hem logic, rot chip, other devices that we run. Let's go and have a look at some media playing. Not some test files on a folder. I could show you 1080p but you all want to see 4K. So this is a trailer of the movie interstellar it's running in 4K it's HEVC. Just look down, worry about our play time and then there. As you can see it started almost instantaneously. I've just got a normal gigabit network here nothing fancy. The greater throughput on the gigabit Nick is very beneficial for much faster playback There you go, player process information HEVC 4K, on a Raspberry Pi, fantastic. If I bring up the debug view you'll see that there are zero frames yet it's not a particularly high bit rate trailer. It's not formatted for the web but good to see. The performance on other 4K videos is not always quite as good. There are still some working progress things to do with 4K. It's also worth noting that HDR and hybrid log camera are not yet supported. Those are going to take a little bit of time because they're dependent on kernel frameworks that come in newer kernels. So we will have to wait a little while for that to come. It's more likely to be something that comes in code v19 not code 18. Anyway that concludes a quick demo of the Raspberry Pi 4B. Thank you.
