as I was happy to have one Guitar sent to me by LeMaker, here is my first review of this little shinny box.
I was wondering which of power supply from my unused box I could use. I found a power supply with a plug that looks fitting, it’s rated 5V / 2.4A with ground around the plug. I found no description about plug polarity on lemaker’s web site, but the +pin in the middle just sound so common that after a quick prayer, I switched the power on.
Good, it’s starting, with a new 3D lemaker logo. The Guitar was delivered with Android preinstalled on the Flash storage and just quickly show the initial android configuration. The boot was pretty quick, first good surprise.
Globally, android feeling is very smooth, it just work as you want to use it.
Another good surprise, my Logitech k400 combo keyboard was recognized out of the box! When I remember the trouble to make it work with the bananapi with initial android distro, that’s a good progress.
So what’s inside the OS ? Going to the android config, I could see what the build rely on:
Copy the Code
- •Android 5.1.1
- •Kernel: 3.10.37, lee@R710 #3
I went inside the settings menu to personalize the box, was able to change system language to french, change the keyboard layout to azerty, sounds like all the regional setting from android are present. Good.
Network: Ethernet port was just working, I’ll do some test later on it, and Wifi just connected to my network out of the box, with pretty good signal strengh.
Screen: However, to be honest, I have an issue with the build provided regarding screen: For now I did’nt found any way to adjust resolution, despite my full HD screen plugged through the hdmi cable. So for now I’m stuck at 1024*600. That’s ok for starting, but I’ll have to find a way to activate 1920*1080 resolution.
Storage: at user level, the storage is visible with this organizzation:
Copy the Code
- Internal storage is 1.91 GB wide, with 1.39 free out of the box.
- Internal SD card is 2.89 GB wide, with everything available out of the box.
Since I was able to completely reset the android system from scratch, I presume that the lacking space (around 3 GB) is for restoration.
Let’s do some tests:
Antutu (please remember that it’s executed for 1024*600 resolution)
Copy the Code
- <b>Score: 25783
- UX / Multitask: 3055
- UX / Runtime: 2517
- CPU / CPU Integer: 1950
- CPU / CPU float-point : 3061
- CPU / Single-thread integer: 1536
- CPU / Single-thread float-point: 888
- RAM / RAM Operation: 1608
- RAM / RAM Speed: 904
- GPU / 2D Graphic: 2356
- GPU / 3D Graphics: [1024*600] 6560
I'm not yet sure of the CPU frequency, but Pimp my Rom app tell me the max is 1200 MHz and cpu governor is cfq
Let’s try Kodi now. Based on Kodi 15.2 RC3 this is what I tried.
To be sure to test video capacity and not pure Kodi side issues, I started with the set of samples movies found there: http://jell.yfish.us/ . Those are h264 1080p movies with various bitrate, which is more important that testing just HD files.
The movies are accessed from my Synology NAS, which have much more bandwidth and disk speed that what can be done from a 100 Mbps Ethernet NIC.
| Jellyfish Bitrate|| Result|
| 10 Mbps|| Perfect|
| 20 Mbps|| Perfect|
| 25 Mbps|| Perfect|
| 30 Mbps|| Perfect|
| 35 Mbps|| Perfect|
| 40 Mbps|| Perfect|
| 45 Mbps|| Perfect|
| 50 Mbps|| Some skips|
| 60 Mbps|| Some skips|
So everything is completely smooth and crispy from 5 Mbps until 50 MBps bitrate, then from 55 Mbps I started to have small frame skips. This is very good, way better that any mkv file you should try.
Then I tried the torture test video file I used to test my bananapi, to be found there: http://forum.kodi.tv/printthread.php?tid=139566
I had mixed result. The first time it played with some small lags in the middle (never achieved that on my Banana Pi !) The second run was just completely smooth.
During this playback, I had the command “top” running in adb. The result is:
Copy the Code
- User 23 %, System: 24%, IOW 0%, IRQ 10%.
But then I tried other file format. VC1 is just a no go, almost not playing. Will try more later.
To be able to interact with the android system for advanced interaction, you have several options. The one I used is to use adb.
The Android ROM is completely ready for that, but on Windows size, you need two actions:
Once android is booted (not in ADFU mode), the command “adb shell” let you launch command on android. If you need to use “su” from android shell, do not forget to acknowledge the Super-Su prompt in android main screen.
