How to resize feed to RPi screen

[Tony359]

Hi all - I've managed to install camplayer but so far I haven't found a way to rescale my Reolink feed to the 7" RPi screen. I am using the SUB feed (I don't even want to try to ask the Pi to rescale the 4K H.265 feed) which is 640x630 (only option I have). It should fit the RPi screen TBH but it doesn't.

One thing, when Camplayer starts I see it sees a 0x0 HDMI monitor, it may have to do with the fact that I have set up a Full-HD virtual display for when I need to remote into the RPi and want to work on a larger display?

I tried some advanced options (set the width manually for example) but no luck.

any help appreciated! Thank you

update: adding both WIDTH and HEIGHT in the config scaled the picture ok - but I have a black bar on the right and the picture seems to be slightly horizontally squashed. Any way to compensate for that?
