Thanks for your answers. Where can I get Jun's latest drivers for new hardware to test. please? Is any link to download them?
Yes, you're right. My hardware is working fine excepting unexpected shutdowns and reboots when using Video Station. They are related to hw decoding and hw transcoding of video files. This is a reason why I am looking for any improvements in this area.
I have tested my ASRocks J3455-itx with almost all extra files I have found on this forum:
Original Jun's extra from 1.04b loader, Olegin extra and your pack of extras from this post v0.6 (I have tried your pack yesterday) gave me the same result. I have always done a clean installation with new usb drive and new ssd. In all mentioned cases I have got successful installation, then manual reboot, then system started normally but /dev/dri didn't exist and hw transcoding gave error as well as reboot and shutdown didn't work.
With real3x and Hostilian extras, I have got successful installation, then system restated itself normally, /dev/dri was present, offline hw transcoding in Video Station was working ok at least I have tried to transcode some small video files like jellyfish ones but online hw transcoding in Video Station gave unpredictable result. It could work for short time and then freeze and reboot or system just goes to reboot straightaway . Reboot and shutdown work fine.
As I described above, the original driver fails but extra with extracted one gave a bit better result but it is very unstable...
Is there any software to test and benchmark freshly installed DSM? Thanks.
