It turns out that adding -timeout works, with a value in microseconds. I can't any non-rtsp documentation on it though. ________________________________ Van: Martijn van Beurden Verzonden: woensdag 22 mei 2019 14:14 Aan: ffmpeg-user@ffmpeg.org Onderwerp: Is it possible to timeout a JPEG dump Hi all, Currently I have a script running that dumps snapshots from a security camera MJPEG stream with this command ffmpeg -i http://admin:admin@192.168.10.4/channel2 -c:v copy -f image2 -strftime 1 %Y-%m-%dT%H:%M:%S%z.jpg However, in case the network has a dropout for some reason, the connection is broken but FFMPEG hangs. The process isn't stopped (apparently the broken connection is not detected) and there is no way of detecting this. Is there any way to set a timeout between frames arriving or something similar?
