AW: filesink cannot write output file more than 2048 MB, windows, gstreamer 1.16.1 mingw x64

[Thornton, Keith]

Hi,
The last statement was not quite correct. The 2048MB limit is a feature of the target file system. FAT32 can't handle files larger than 2GB but NTFS can. I have just recorded a 3GB large file under windows 10 on an NTFS HD.

That is a windows issue that cannot be fixed. (Well it can, but it is low down in windows) James
