Hi all,
firstly I want to express sincere appreciation for everyone who works on this project and the adaptation to the RPi4. I've participated in open source projects and commend the status of this project and the benefits for all.
I installed the LibreELEC 9.2.3 version a few days ago (LibreELEC-RPi4.arm-9.2.3.img) following instructions with the USB-SD creator. All went fine, booted up good. Added SMB network shares, no issues. Had the HDMI on Port 1 so had no sound but then moved to Port 0 and all good. I had been running Kodi previously on a small desktop, for about 8 years.
FYI I've got my RasPi hooked up to a Panasonic 50" 1080p TV via the HDMI.
I've got two issues/questions:
1) Sample:
When I try 4K H265 HEVC GoPro clips (ran off the SD card, not the network), they appear to play, however, the video portion is playing at a slightly reduced speed. The audio is OK, but the video plays at some delayed framerate .. It plays smooth though. You can see in the sample. The loss of sync isn't totally obvious but you'll notice when the sound of cutting finishes he's still cutting the wood. The reason I want to be able to play 4K clips is mainly to play GoPro footage I get from various sources, I don't want to re-encode them I'd rather play them and have them downscale to my TV.
2) Sample:
When I play regular mp4 1080p clips from my Canon Camera (local or network) that I have played on previous Kodi installs for years succesfully, the clips play fine, except for maybe ~5 seconds at the beginning that are just slightly out of sync, which the video then returns in sync after a black screen blip. See sample video, ~0:07 mark. Not obvious in this clip but audio and video slightly out of sync and then corrects at that black screen blip. It does this for all those clips.
Also I did play the Korean concert clip from the Kodi Sample page succesfully. Samples - Official Kodi Wiki
MediaInfo output shown below for both files.
Thanks anyone for support on this matter! Otherwise really like the setup!
