This is not a problem with ffmpeg. You should configure your shell to set the tty to a sane state before a prompt. With zsh, it is done with "ttyctl -f". > is there a way to have ffmpeg exit gracefully when the pipe is broken? Again, it is not ffmpeg's responsibility: Compare: ssecem ~ $ sh -c "dmesg" | head -n 1 [ 0.018123] On node 0, zone DMA32: 1580 pages in unavailable ranges zsh: exit 141 sh -c "dmesg" | zsh: done head -n 1 ssecem ~ $ sh -c "trap '' PIPE; dmesg" | head -n 1 [ 0.018123] On node 0, zone DMA32: 1580 pages in unavailable ranges dmesg: write error zsh: exit 1 sh -c "trap '' PIPE; dmesg" | zsh: done head -n 1 Regards, -- Nicolas George
