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

[Артем Семенов]

Hello, James.

You are wrong, it's not a "low down" windows issue.

I found this:

*1. "filesink: fails with matroskamux when writing files larger than 2GiB on Windows"
*https://gitlab.freedesktop.org/gstreamer/gstreamer/-/issues/579

*2. "meson: Ensure large file support for fseeko"*
https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/517

And it looks like this fix was backported into 1.16 (1.16.3).
