  • Extract Less Keyframes (ffmpeg)

    6 juillet 2019, par Barnee

    I’m trying to extract keyframes from a large video I have. The problem I’m seeing is that it is extracting far too many, leaving me with many very similar images.

    Below is what I am currently using (from terminal)

    ffmpeg -i video.mov -vf "select=eq(pict_type\,I)" -vsync vfr thumb%04d.png -hide_banner

    What would be great is if there was a way I can either make it only output 1 in 5 keyframes. Or what would be even better is if there is a way I can make it only output if the frame is over x% different from the previous one.

  • FFMPEG Scan and Convert Movie files and Delete Original - reclusively

    29 mai 2021, par Frodo Baggins

    I have folders within folders that have movie files, some of them are .mp4, .avi or .mov/.MOV. I need to re-compress them into H264 High Quality (Lets say, 10MBPS) and delete the originals when complete. I have the following code, but this is for audio and I don't know where to go from here. I am using Mac terminal.

    


    for i in *.ogg; do ffmpeg -i "$i" -b:a 320000 "${i%.*}.mp3"; done

    


  • Recording a video by webcam on Raspberry Pi [on hold]

    9 août 2019, par Stan Eskin

    Need a python3 script for recording a video by a USB webcam on Raspberry Pi. For instance, I’d like to capture a video to the RasPi’s SD card when a motion sensor gives the signal.

    I’ve found this code for the terminal :
    ffmpeg -f v4l2 -r 25 -s 640x480 -i /dev/video0 out.avi

    Unfortunately, I don’t know how to implement it in my python3 script.
