Description

When downloading incomplete live, ffmpeg does not stop in the end, cycling on index.m3u8. When running it manually it is possible to stop it by pressing 'q'. I tried to stop it with ^C, but it killed ffmpeg. Why you use ffmpeg, but not let it terminate normally? No log because live is finished now. I know about mpegts or additional ffmpeg options, but why it not enabled by default if without it it is just impossible to get valid file?

ffmpeg will be terminated correctly if you won't hit Ctrl+C multiple times.
