Idan,
The warping kernel works on a multiple band dataset by using a single
working data type, which should be the "max" of the types of the input
bands, so here int16. I believe this is working, but here the issue is
more at the creation of the dataset itself than during the warping. This
is due to
https://github.com/OSGeo/gdal/blob/3302b5c9cb62191df3409676aa97fced07c92c3b/gdal/apps/gdalwarp_lib.cpp#L3017
. GDALWarpResolveWorkingDataType() should likely be used instead

Hi all,
I was trying to warp a ds with a byte band and an int16 band and got a
ds with two byte band.
Is warp using the first band data type for all the output bands?
Is that a bug?
If multiple band types are not supported - maybe max(band types) could
be a better default (assuming no explicit output type) ?
Kind regards,
Idan
