I'm trying to create ECW mosaic from multiple ECW files. It's trying to mosaic 3693 ECW tiles. I have a floating licence for FME.
This is the workflow I'm running.
Below are the errors I'm occurring:
2023-07-10 20:42:10|24575.6| 0.0|ERROR |ECW writer: Could not open compression task Output image size exceeds license
2023-07-10 20:42:10|24575.6| 0.0|ERROR |ECW writer: Failed to write dataset. This may occur if you have insufficient privileges to write this file, or if insufficient disk space is available
2023-07-10 20:43:13|24638.5| 62.9|ERROR |ECW writer: An error has occurred. Check the logfile above for details

ECW support is something that Safe licences from Hexagon and the first error line seems to indicate it's related to that licensing.
From the ECW format overview in the FME Help:
"and FME usage of the ECW SDK limits image size to less than 1000 gigapixels"
Checking the Hexagon help seems to indicate that the 1000 Gigapixels is already the top tier available so as far as I can tell, that is really the issue: Hexagon won't allow any other 3rd party software to write ECW files larger than 1000 Gigapixels
Resampling may be an option, depending on what you want to do with the imagery, or maybe generate separate files.
