Hi, guys. First of all, let me congratulate everyone for making amazing progress on making LibreELEC work as perfect as possible on Rockchip devices.
I thought I'd give feedback regarding my overall experience after testing various current images for RK3328 devices and hopefully this feedback will help improve any future releases.
First off, I am running an R10 RK3328 Android TV Box.
Second, my preferred LibreELEC build is the latest MVR9 image (LibreELEC 9.2 Alpha) which you can download right from this site: Rockchip – LibreELEC
I have tested all the LibreELEC 9.2 Alpha images for RK3328 devices. They all boot into LibreELEC but MVR9 image works best for me because I get Internet connection via Wi-Fi (wired connection doesn't work) and I get sound from my speakers via AV port by selecting the I2S analogue sound option in Kodi settings.
Regarding other LibreELEC 9.2 Alpha versions I tested, some of them don't have Internet at all / others have Internet via Ethernet but no Wi-Fi, but those images don't have the I2S analogue sound option so I get no sound to my speakers.
Okay, that would be my feedback regarding sound and Internet.
Now, to the second part, which is video playback.
Again, LibreELEC 9.2 Alpha MVR9 image works best for me. There are only two small problems: a) colors in 4K videos seem to be a bit washed up. That's especially apparent if I bring up navigation bar during playback. Then the colors become even more pale
b) MPEG-4 files are extremely choppy as LibreELEC 9.2 Alpha doesn't yet use HW acceleration for those files, so I guess that's where the problem lies.
The two latest developmental images I've tested have other bugs, but they fix these two video playback problems for me.
First off, regarding washed up colors in 4K videos, the latest MVR9 LibreELEC version on this link (LibreELEC-RK3328.arm-9.80-nightly-20190719-235fdbc-box-trn9.img.gz) has better colors, but here videos get a bit choppy when bringing up the navigation bar.
And secondly, regarding choppy MPEG-4 videos, the latest image by Kwiboo (LibreELEC-RK3328.arm-9.1-devel-20190512173254-bdfaff1-box-trn9.img.gz) fixes that problem, but the playback of other video formats has gotten worse and very, very buggy.
So, if you could somehow merge the official RK3328 MVR9 image with the good points from these two other images, it would improve things a lot.
I guess my recommended list of fixes would be:
1) HW acceleration for MPEG-4 files
2) improved 4K video colors
3) Ethernet connection available on MVR9 image.
Thank you for reading.
