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? Console output is this: ffmpeg version N-93674-g1e01f66822 Copyright (c) 2000-2019 the FFmpeg developers built with gcc 7 (Ubuntu 7.3.0-27ubuntu1~18.04) configuration: --pkg-config-flags=--static --extra-cflags='-static -static-libstdc++ -static-libgcc -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic -fPIC' --extra-ldflags='-static -static-libstdc++ -static-libgcc' --extra-libs='-lm -ldl -lpthread -lz -lrt' --enable-gpl --enable-nonfree --enable-libvorbis --enable-libtheora --enable-libvpx --enable-libopus libavutil 56. 26.100 / 56. 26.100 libavcodec 58. 52.100 / 58. 52.100 libavformat 58. 27.103 / 58. 27.103 libavdevice 58. 7.100 / 58. 7.100 libavfilter 7. 49.100 / 7. 49.100 libswscale 5. 4.100 / 5. 4.100 libswresample 3. 4.100 / 3. 4.100 libpostproc 55. 4.100 / 55. 4.100 Input #0, mpjpeg, from 'http://admin:admin@192.168.10.4/channel2': Duration: N/A, bitrate: N/A Stream #0:0: Video: mjpeg (Baseline), yuvj420p(pc, bt470bg/unknown/unknown), 1920x1080 [SAR 1:1 DAR 16:9], 25 tbr, 25 tbn, 25 tbc Output #0, image2, to '/srv/camera/snapshots/zuidwest/%Y-%m-%dT%H:%M:%S%z.jpg': Metadata: encoder : Lavf58.27.103 Stream #0:0: Video: mjpeg (Baseline), yuvj420p(pc, bt470bg/unknown/unknown), 1920x1080 [SAR 1:1 DAR 16:9], q=2-31, 25 tbr, 25 tbn, 25 tbc Stream mapping: Stream #0:0 -> #0:0 (copy) Press [q] to stop, [?] for help [2.0K blob data] [2.0K blob data] [2.0K blob data] [2.0K blob data] [2.0K blob data] [2.0K blob data] [2.0K blob data]
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.
