#2025 closed defect (fixed)

FFMPEG unable to create WTV files > 2GB

Description

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).

I'm marking this important since it's fundamental issue, but if my analysis is incorrect feel free to change it.

Fixed, and >2GB file tested on Windows Media Centre.

Note: Windows Media Centre complains when the .wtv file does not contain an audio track. I will look into this separately.

Thanks, will test it and let you know.
Now if only someone can figure out how to get H.264 in a WTV container, that would be awesome!

Working great, thanks.
