Specify timestamp in ffmpeg video segment command

Question

I have a continuous RTSP stream coming from a camera over the network. I want to dump the stream but in video files of length 1 min each.

I an using the following command

ffmpeg -i "rtsp://user:[email protected]"  -f mp4 -r 12 -s 640x480 -ar 44100 \
-ac 1 -segment_time 60 -segment_format mp4 "out%03d.mp4"

The name of the files being created are of the form out001.mp4, out002.mp4, etc.

I want to include the timestamp (hour and minute) in the name of the file segments eg. 09-30.mp4, 09-31.mp4, etc.

If it is mandatory to provide a serial number for the segment, is it possible to get something like 09-30-001.mp4, 09-31-002.mp4 ?

Answer 1

Appears you need to add the "-f segment" parameter. Here's an example with strftime as well:

 ffmpeg -i your_input -f segment -strftime 1 -segment_time 60 -segment_format mp4 out%Y-%m-%d_%H-%M-%S.mp4

segment_time 60 means 60 seconds, strftime 1 means "enable strftime names"

For me this created files with names like this:

out2015-03-05_10-27-43.mp4
