  • RK3328 4K HEVC stutter frame drop

    Thanks for full answer with multiple solutions :thumbup:

    c) is too long and I want that the player converts on the flight or not, I don't want to encode by myself.

    a) I don't have any other monitor/TV. Rock64 does or not play 4k@60 ?

    b) You mean buying another hardware ?

    Comments:

    a) The desktop resolution is 1080@60.

    Yes the resolution is set to 1080@60 manually fixed in kodi's settings

    b) The whitelist has been configured but the whitelist decision-tree (evaluating what mode from the configuration to use) is not visible when media is played and this normally means adjust-refresh and/or the whitelist are not enabled.

    I can see in yellow every 1920x1080 and every 3840x2160.

    I've also checked bellow whitelist 'Allow refresh 3:2 pulldown' and 'Refresh twices' in Whitelist section.

    c) The family-movie file is 3840x2160@25 but there is no 4K@25 mode in the whitelist or EDID data. This means Kodi cannot play media at its native rate or a 'double' of the native rate (4K@50) and must adapt the content. This does not give great results, and there is also no mention of a rate change in the log so it might be converting 4K@25 to 1080@60?

    I'm pressing o to see information the video is 3840x2160@25 but the video is adapted to 1920x1080 at the screen

    d) The log does not show playback of the BBB file, but this media is 3840x2160@60 and there is a 3840x2160@60 mode available so Kodi will be able to output at the native resolution/refresh.

    Ok

    e) The "Impossible to convert between the formats" error is unusual (first time that I see it) and I'm not sure where in code that comes from, but the mention of scaling also makes me think it might be trying to scale 4K@25 to 1080@60.

    f) EDID data shows "IIyama" which is a Monitor brand. If this is a monitor? using a TV with a full selection of modes, ensuring that adjust-refresh and whitelist are enabled and set correctly (as per the article I linked before) the results should be better. The EDID data shows 4K@25/50 and [email protected]/24/25/29.97/30 modes are missing; although enabling rate-doubling means the 25/29.97/30 modes can match with 50/59.94/60. The lack of [email protected] mode means HD movies must be CPU scaled to [email protected] and this can impact overall device performance.

    The monitor is IIyama ProLite XB3288UHSU which

    Native resolution3840 x 2160 @60Hz (8.3 megapixel 4K UHD)

    I've also : Set the Adjust Refresh setting to "On Start/Stop"

    g) If this is the only screen you have, download Handbrake and convert the problem files to 4K@30 and they should play better on a device that has a 4K@30 (and 4K@60) mode. Configure the phone? to use 4K@30 and then future movies don't require you to convert them with Handbrake.

    This is the only screen I have.

    I'm playing videos by using Kodi interface, how can I configure to use 4K@30 ?
