    Software deinterlaced 1080i content is no drama as long as you do not whitelist the 25/29.97/30 Hz refresh rates in video settings which allows Kodi to run at 50/59.94/60 instead.

    I have nothing in my whitelist and the "resolution" is 4096x2160p, "refresh rate" 30, "limit gui size 1080p.


    If I whitelist 1920x1080p the TV switches resolution when I watch HD TV and it works, but is obviously slow to switch as it renegotiates.


    But my TV won't take SD content like DVDs so can't pull the whitelist trick. Or any SD TV channels.

    It runs okay at 4K resolution output with the GUI set at 1080. But there is still tearing on the GUI at this time. The GUI at 4k is pretty slow.


    The big factor for me is that it lacks deinterlace in hardware making SD and HD (1080i) video from broadcast sources unusable. Video stutters and freezes. This is stopping me replacing my pi3 with this.


    Actual 4k h265 seem okay on the few test files I have provided the data rate isn't too high, struggled with 140Mbs file I tried.

    Here is a on expirebox

    A friend of mine passed onto me that he has problems with LibreELEC playing on a RPi2, with the HW codec keys installed (if that's relevant), a mkv container file with VP9 and OPUS inside.


    The same issue occurs on my install (and has done for a number of releases), I'm running 8.2.5.


    The symptoms are the video plays very slowly (practically frame by frame) and the audio initially sounds normal, but seems to get upset eventually.

    There is nothing in the log file that is complains during this playback. The file plays fine on VLC.


    Any ideas? I'll try and attach an example file or link to it.
