There is no more video written to the file at this time but ffmpeg is not stopping. If i stop it manual after 30 hours the file is only 26 hours 30 minutes long.

Please test current FFmpeg git head and provide the command line you tested together with the complete, uncut console output to make this a valid ticket.

How can i use git head?

Uncut console output is very long after 26 hours.

The conditions to accept this error are too high.
