[FFmpeg-user] timeout ffmpeg, Ctrl+C -> Immediate exit requested

Hi.

That means your timeout utility got impatient and sent a second SIGINT.
The first interrupted the transcoding process and started the flushing.
The second interrupted the flushing itself.

Three SIGINT in a row interrupt everything immediately. On the whole it
is a rather reasonable behavior. Just configure timeout to wait enough
time between the first and second.
