Improved deinterlace on Pi4 in latest nightlies

    Recent LE12 nightly builds (since this PR) now support bwdif deinterlace, which has had recent neon optimisation in ffmpeg.

    The quality of this deinterlace is much better than the previous firmware accelerated bob deinterlace.

    In fact it's generally thought to be better than yadif.

    See here for deinterlace comparisons.

    bwdif is shows as "Bob-Weave" in the table.

    To use it you want to disable settings/player/video/Allow hardware deinterlace with DRM PRIME

    which allows the better quality software deinterlace to be used. We may make this a default option if feedback is positive.

    You really want a Pi4 for HD resolution (Pi2/3 should handle SD).

    Unfortunately we currently have issues with our CI ATM (it's being investigated) so we don't have builds with the deinterlace improvement yet.

    I hope we can resolve the issues soon and new builds are up in the next few days.

    so long,

    Hias

    I've updated a build I made from current head of master here.

    A quick test updated, and ran, and included the deinterlace support.

    copy to /storage/.update and reboot to update. Be aware this is a master build, rather than nexus.

    I don't think much has changed that would cause an issue with updating, but as always having a backup is useful.
