Because my TV has a USB port and plays really faster the 4K demos I have BUT ROCK64 CANNOT.! It only shows some lines across the screen of my 4k tv, both on LibreELEC and KODI.! But 1080p videos are played well..!!! So what am I doing wrong. As I mentioned before on android 7.1 Tv images the system wouldn't even boot and was going slowly as a turtle. Things were different with LibreELEC using the same SD Card..!!! Can anyone explain please??? One more thing just to clarify this , I am playing video locally from a USB hard drive.Not on line.! (I tested several sticks and external drives ...for someone to go to this conclusions)
So obviously this board isn't capable of playing True 4K videos at all.! Cannot even handle android 7.1 TV on it's own...!!Anyway ...I gave up on this board and now I am using it as a simple file server with openmediavault on it. BUT BUT BUT I found something really disturbing .. I was having problems with my openmediavault because I was using my external small usb hard drive directly powered from the USB 3 port of ROCK 64 with a power supply 5.2 volt 10 Amp and to my surprise it COULD'NT handle it. As reading the logs I was having multiple connections and disconnections of my external hard drive at random times..!!!! Now I am using the same drive and one much bigger but self powered from it's own source and everything is working fine.No disconnections nearly a month or so.
As a conclusion , this board cannot handle well USB3.0 external drives and having problems during time. The funny thing is that the problem was not instantly occurred but during time, as I said earlier. The power supply I am using is the same as a PC power supply. I measure it during operation and it actually can deliver more than 12Amps of continue power..!!! Does the rock64 needs more??? I do not think so.!
I TOTALLY AGREE WITH dkryder .! I will never do the same mistake at all.!
Dear Trash_Can_Man,
I know very well that raspberry pi3 or any raspberry cannot play 4K at all BUT it can sure play 1080p on a 4K TV much smoother that the ROCK64. This is a fact because I have measured both during playing in linux and raspberry is the WINNER on the same resolution.!!!! Sorry to say that but this is the truth.
Winner in what regards? if both devices run a 1080 video (and both can totally do it) where is one ahead of the other? i see ZERO skipped frames on my rock64 runing 1080p videos, ever, and the picture quality looks fantastic on my lego eyes...
Im feeling that you are mad because you found an "issue" that is documented and mentioned on several forums...and what is even worst is that said issue probably is on the HDDs and not on the rock64 since you say yourself that you need to give extra power to the drives and no matter how much power you give to the board it wouldnt matter (wich makes sense, the board is protecting the drives against any power surge that can go thru)...the disks seems to not totally respect the standard randomly and ask more power from the usb port...
In fact you found on this situation one of the more gross differences between a usb2 device (or an usb3 device plugged on a usb2 port) and a real usb 3 device working at usb3 speed, and the difference is the power consumption (or to be more precise power need spikes even far away from what the standard allow)...thats why again its not fair to compare the rock64 to a raspi...different tools for different tasks...
You can see the glass half full or half empty, only you can change the point of view...IMHO the rock64 works fine for both tasks, and yes, i have 2 rock64s (1omv+1libreelec) and with the proper setup they work PERFECT and super stable, again, IMHO...glass half full...
