[Odroid-C2] 4K MKV Playback

  • I found some 4K Matroska video films that cannot be played in 12.2.0 and 13.0, but yes in 9.0 ¿? After a pair of minutes playing, they start to pixelate the image, pause and finally stop with the screen in green colour. Even sometimes Kodi reboots.

    I use the same hardware and settings during the tests (an Odroid-C2).

    Any idea?

    LE 9.0 uses the legacy vendor kernel and amcodec in Kodi. LE 10.0 onwards uses the upstream kernel which reimplements hardware decoding (but the implementation is incomplete) and Kodi dropped support for amcodec in 2017 as part of an intentional purge of prioprietary codecs and refocus on standards.

    TL/DR: the codebases are completely different and while most media plays reasonably well on a C2 it is not pefect and will not work with all media for all users. The upstream codebase is mature and stable for practically everything except media capabilities, where work stalled years ago and has never resumed. You may find that some media is badly encoded and re-ripping from the original sources or re-encoding makes things more playable.

    NB: mkv is a container not a format so it's hard to comment further without knowing what the actual format was (although HEVC is the most likely answer).

  • Many thanks for your comprehensive explanation, it's clear for me now. After spending lots of hours checking different LE versions, I realized that the only one that works for me is the 9.0 that I already have installed in the past.

    I know it's because I use old hardware (Odroid-C2) but as I only use Kodi for films and series is enough for me. I installed the The Movie Database Phyton add-on and in this way I can continue download films information.

    And yes, you're right, after checking with MediaInfo I have seen that all the "problematic" films are HEVC.
