Any chance of a tweak to whitelisting logic?

There’s a slight problem with the whitelist logic on my Vero 4K+. It seems very likely that this is a Kodi issue and not an OSMC one; but there is a historical precedent for OSMC using different whitelist logic from vanilla Kodi, so I’m wondering if this issue could also be fixed in an OSMC-specific way? (Hence I’m raising this as a feature request rather than as a bug report!)

The problem is with videos that have a resolution of 960x540, with a frame-rate of 25 or 50fps. (These are quite common nowadays on iPlayer). With all available resolutions whitelisted, Kodi defaults to playing these at 576p/50Hz. This means we are losing some of the horizontal resolution, by downscaling from 960 pixels to 720; and the way the whitelist is supposed to work (I think!) is that it should never result in a video being downscaled, only upscaled. (There’s obviously some vertical scaling involved as well).

It seems obvious to me that Kodi should be switching up to 720p/50Hz, or 1080p/50Hz (or maybe 1080p/25Hz if it’s a 25fps video).

Is this possible?

Yes. It will be in the next update.

This should now be in the staging repository.

Finally got around to testing this, and yes, it’s working nicely. :+1:


Come to think of it, there’s another bit of whitelist logic that seems odd to me. I’ve been playing some videos today that are 2160p/25fps. I’ve got 2160p/25Hz whitelisted. But the output mode defaults to 2160p/50Hz instead of 25. That wouldn’t be a problem except that the Vero 4K+ seems to have occasional issues with outputting 25fps at 50Hz - sometimes leads to jerky playback.

So, low priority, but maybe that could be tweaked too at some point? In general, if there’s a mode that exactly matches the video’s dimensions and frame rate, it doesn’t make sense to output at double the refresh rate; that should only be a fallback if there’s no exact match.
