LibreELEC-X8-H_Plus.arm-LE9-Kodi_18.1.img => can you try this one? this is the latest release.
Tried it, these are the results:
HARDWARE :
Minix X8H-Plus;
1)old hdmi Samsung tv/monitor "syncmaster 933hd" (only 1366x768 or 1280x720@50hz);
2)hdmi projector (up to 1080p 24hz) + Yamaha 5.1 receiver (via minix optical spdif);
working SDCARD
SOFTWARE :
LibreELEC-X8-H_Plus.arm-LE9-Kodi_18.1.img installed on (and running from) SDCARD
---All tests performed with amlogic video hwacceleration on---
Previously i had tried LE 18.0 with my old Samsung TV/monitor, it gave problems with hwacceleration on
i whitelisted 1280x720@50hz only, disabled adjust refresh rate, but system crashed soon after first video playing.
This setup still gives the same problem on 18.1
18.1 behaves exactly like 18.0:
To reproduce the crash:
keep amlogic hw video acceleration "on", set resolution to 1280x720@50 only, no adjust frame rate:
play a video (i used h264 youtube files),
try to rewind/fforward/stop it, or try to change video : system crashes/freezes. (i tested youtube and other video addons, always the same problem)
rebooted various times: nothing changes.
(only disabling hwacceleration solves the problem).
THEN
I disconnected hdmi from my Samsung TV, and connected Minix to a 1080p24hz-capable projector.
Without reinstalling LE 18.1: just switching monitors.
I whitelisted 1280@50hz, 1080p@50, 1080@60, 1080@24fps and Enabled changing resolutions and refresh.
then i switched LE18.1 to 1080@50hz
System magically starts working. tested LE18.1 playing Youtube h264 videos for 30 minutes. everything ok.
dts5.1 on spdif works (for local files only... I can't get 5.1 working for youtube).
then i put again only 720p50hz in whitelist: Old Problem returned : crash on stop/ff/rewind/ChangeVideo.... reboot, try again.... same crash
whitelisted 720p ,1080p24, 1080p60 1080p50.
Set to 720p,adjust framerate off : crashes on stop/ff/rewind/ChangeVideo.
enabled adjust framerate : still crashes on ff/stopping play
put in 1080p@50 : system magically returns to work
put back in 1280x720 : still works.
Summary: LE 18.0 and 18.1 give identical problems if minix is connected to a 1280 only tv/monitor.
They need to work at 1080p at least once after install.
