More gdal-dev, qgis-dev gremlins reading tiffs

[houska1]

Thanks for fixing LERC (#739) Unfortunately, there's some additional tiff reading issues in qgis-dev relying on gdal-dev 3.6.0

tiffs with the following structure (gdalinfo) that load fine in qgis 3.24.2 using gdal 3.4.3 now fail to load in dev:

Image Structure Metadata:
  COMPRESSION=YCbCr JPEG
  INTERLEAVE=PIXEL
  JPEGTABLESMODE=1
  JPEG_QUALITY=75
  SOURCE_COLOR_SPACE=YCbCr

The qgis error message is:

2022-05-09T06:20:48     WARNING    201404 DRAPE IR fc (RVCA) : C:/...path.../DRAPE 2014 IR compressed.tif, band 3: IReadBlock failed at X offset 23, Y offset 30: TIFFReadEncodedTile() failed.

I've made the above referenced tiff available at ​https://www.dropbox.com/s/jnu5iwg5ehlll34/DRAPE%202014%20IR%20compressed.tif?dl=0 until closure of this ticket. Warning 50Mb. Similar failures on other similarly encoded tiffs.

Thanks!

"completely unrelated."

Gentle ping on this. A solution seems to be proposed at ​https://github.com/OSGeo/gdal/issues/5736 (though it went over my head).

No problem for this to sit here if it's just a bleeding-edge dev branch issue. But commenting to make sure that -- if unaddressed -- it doesn't break non-dev QGIS 3.26.0 in 2 weeks. I *think* the trigger point will be whether that non-dev build will continue to use GDAL 3.4.X or move to 3.6, but I'm not sure.
