Use ffmpeg to stream video from a dahua 4300s to a file or files
You can use ffmpeg to directly pull frames off of a dahua 4300s at full resolution. May be a good alternative to pricey dvrs which likely cannot record at full resolution, may not work with the camera, or are prohibitevly expensive
Simple Stream to file
Simple stream to file. Full resolution
ffmpeg -loglevel debug -rtsp_transport tcp -i "rtsp://admin:admin@198.175.207.61:554/live" \
-c copy -map 0 foo.mp4
Break streamed file into time segments
ffmpeg can save file in arbitrary segments at fixed intervals. In this example, we save a new file at
10 second intervals, but the value for segment_time
can be any positive integer
ffmpeg -rtsp_transport tcp -i "rtsp://admin:admin@198.175.207.61:554/live" \
-f segment -segment_time 10 -segment_format mp4 -reset_timestamps 1 \
-c copy -map 0 test%d.mp4
Timestamped output
Output files can be timestamped as well.
ffmpeg -rtsp_transport tcp -i "rtsp://admin:admin@198.175.207.135:554/live" \
-f segment -segment_time 10 -segment_format mp4 -reset_timestamps 1 \
-strftime 1 -c copy -map 0 dauphine-%Y%m%d-%H%M%S.mp4
Select stream to read from.
A different url is used to select the substream. Set subtype
to 0 for main hi-res stream, or
1 for low res substream. Channel looks to always be set to 1
ffmpeg -rtsp_transport tcp -i "rtsp://admin:admin@198.175.207.135:554/cam/realmonitor?channel=1&subtype=1" \
-f segment -segment_time 10 -segment_format mp4 -reset_timestamps 1 \
-strftime 1 -c copy -map 0 test-%Y%m%d-%H%M%S.mp4

Nice! It works also with IP 3G Cam V380e aka 360eye, handling properly credential, port and URI to connect through RTSP.
