I am working with ffmpeg.
I can get a thumbnail from rtsp via command like below.
ffmpeg -itsoffset -4 -f rtsp -rtsp_transport tcp -i rtsp://fostv.com:554/test/smarttv_sample.ts.pac -vframes 1 -s 420x270 /home/guest/ffmpegsample.bmp
The problem is what I want is take thumbnail from position which I want.
if it is local file, I can do that with "-ss" option. But how in streaming situation?
I want to take thumbnail from 10 minutes after video started.
- May be somebody knows how to jump start position of rtsp protocol streaming.
give me some ideas, Thanks.
