2025,FFMPEG unable to create WTV files > 2GB,ramitbhalla,pross,"FIRST of all thanks @Peter Ross for fixing the seek in WTV files.

Summary of the bug: When I try to convert TS files to WTV files and if the converted file is > 2GB, it is unplayable.

How to reproduce: Here is a very simple remux from TS to WTV, as you can see the conversion itself is showing no errors, but if the destination is > 2GB the file is not playable by WMP, however if I use a smaller source so the destination is < 2GB it works fine (same settings).
