  • ffmpeg : What is the best practice to keep a live connection/socket with a camera, and save time on ffprobe

    15 mai 2022, par Jeff Strongman

    Today... I used the following command : with subprocess.PIPE and subprocess.Popen in python 3 :

    


    ffmpeg -i udp://{address_of_camera} \
  -vf select='if(eq(pict_type,I),st(1,t),gt(t,ld(1)))' setpts=N/FRAME_RATE/TB \
  -f rawvideo -an -vframes {NUM_WANTED_FRAMES} pipe:`


    


    This command helps me to capture NUM_WANTED_FRAMES frames from a live camera at a given moment.

    


    However... it takes me about 4 seconds to read the frames, and about 2.5 seconds to open a socket between my computer and the camera's computer.

    


    Is there a way, to have a socket/connection always open between my computer and the camera's computer, to save the 2.5 seconds ?

    


    I read something about fifo_size and overrun_fatal. I thought that maybe I can set fifo_size to be equal to NUM_WANTED_FRAMES, and overrun_fatal to True ? Will this solve my problem ? Or is there a different and simpler/better solution ?

    


    Should I try to record always (no -vframes flag) store the frames in a queue(With max size), and upon a wish to slice the video, read from my queue buffer ? Will it work well with the keyframe ?

    


    Also... What to do when ffmpeg fails ? restart the ffmpeg command ?
