MeLE Quieter3Q Review – Ultra-thin fanless mini PC tested with Windows 11, Ubuntu 22.04

MeLE has released a new and updated version of the Quieter mini PC called the Quieter3Q. Like before, it is a passive mini PC but now features the latest low-powered Intel Celeron Jasper Lake CPU and an upgraded PCIe 3.0 x2 M.2 2280 NVMe SSD slot. MeLE has kindly sent one for review and I’ve looked at performance running both Windows and Ubuntu and connecting an eGPU. MeLE Quieter3Q Hardware Overview The MeLE Quieter3Q is physically the same as before consisting of a 131 x 81 x 18.3mm (5.16 x 3.19 x 0.72 inches) rectangular plastic case with a metal base plate. The top half of the case is finely grooved to mimic the fins of a heat spreader but is made of plastic rather than metal to allow reception to the WiFi antennas as one is directly connected to it. As a passively cooled mini PC, it uses Intel’s […]

Khadas VIM4 SBC review – Part 3: Ubuntu 22.04

Here’s the last part of Khadas VIM4 review with Ubuntu 22.04 “Jammy Jellyfish”. You may want to check out our previous parts with the unboxing and first boot, followed by Android 11 if you haven’t already done so. Ubuntu 22.04 installation on Khadas VIM4 I used the same method of installation with OOWOW firmware that can download the image directly from Khadas server, and install it to the eMMC flash. Since I already had Android 11 running on the board, I had to keep pressing the function key (middle), then shortly press the reset button, before releasing the function key and entering OOWOW interface. From there, I selected Ubuntu 22.04 Gnome, and went ahead with the download. The download was fast with the 758.2MB compressed image downloaded in a couple of minutes, then I simply selected “Install” to go further, and replace Android 11… .. and after rebooting the board […]

Rockchip RK3588 CPU module exposes more I/Os through four board-to-board connectors

We’ve already seen several Rockchip RK3588 modules with Firefly Core-3588J, Turing RK1, and Banana Pi RK3588_CV1, all with an edge connector to insertion into the carrier board. Rongpin RD-RK3588 system-on-module is a little different with four board-to-board connectors that enable a slightly more compact design, and should expose more I/Os than say a 314-pin MXM edge connector. The module ships with up to 16GB of RAM, 128 GB of storage, a Rockchip RK806-1 PMIC, and the company also offers a development kit with RD-RK3588-B baseboard fitted with the module for evaluation and early software development. RD-RK3588 board-to-board module RD-RK3588-C core module specifications: SoC – Rockchip RK3588 octa-core processor with 4x Arm Cortex-A76 cores @ up to 2.4 GHz, 4x Arm Cortex-A55 cores, Arm Mali-G610 MP4 GPU with support for OpenGL ES3.2, OpenCL 2.2, Vulkan1.1, 6 TOPS NPU, 48MP ISP, 8Kp60 video decoding, 8Kp30 video encoding System Memory – 4GB, 8GB, […]

Linux hardware video encoding on Amlogic A311D2 processor

amlogic a311d2 h265 hardware video encoding sample

I’ve spent a bit more time with Ubuntu 22.04 on Khadas VIM4 Amogic A311D2 SBC, and while the performance is generally good features like 3D graphics acceleration and hardware video decoding are missing. But I was pleased to see a Linux hardware video encoding section in the Wiki, as it’s not something we often see supported early on. So I’ve given it a try… First, we need to make a video in NV12 pixel format that’s commonly outputted from cameras. I downloaded a 45-second 1080p H.264 sample video from Linaro, and converted it with ffmpeg:

ffmpeg -i big_buck_bunny_1080p_H264_AAC_25fps_7200K.MP4 -pix_fmt nv12 big_buck_bunny_1080p_H264_AAC_25fps_7200K-nv12.yuv

1	ffmpeg -i big_buck_bunny_1080p_H264_AAC_25fps_7200K.MP4 -pix_fmt nv12 big_buck_bunny_1080p_H264_AAC_25fps_7200K-nv12.yuv

I did this on my laptop. As a raw video, it’s pretty big with 3.3GB of storage used for a 45-second video:

ls -lh
total 3.3G
-rw-rw-r-- 1 jaufranc jaufranc  40M Aug  5  2011 big_buck_bunny_1080p_H264_AAC_25fps_7200K.MP4
-rw-rw-r-- 1 jaufranc jaufranc 3.3G May 21 15:03 big_buck_bunny_1080p_H264_AAC_25fps_7200K-nv12.yuv

ls -lh

total 3.3G

-rw-rw-r-- 1 jaufranc jaufranc 40M Aug 5 2011 big_buck_bunny_1080p_H264_AAC_25fps_7200K.MP4

Now let’s try to encode the video to H.264 on Khadas VIM4 board using aml_enc_test hardware video encoding sample:
