  • Using FFMPEG : How to do a Scene Change Detection ? with timecode ?

    24 novembre 2016, par Mozart

    Based on this article it seems that it is possible to use FFMPEG to detect scene change in videos :
    http://www.luckydinosaur.com/u/ffmpeg-scene-change-detector

    Now I have a video that displays a book text and when the text (word or sentence) is spoken it gets highlighted.
    Something like this audio book : https://youtu.be/lA7L6ZNVKjc

    I need to know the timestamp when the text gets highlighted (hence scene change), this will allow me to add timestamp tags on my youtube video, so it becomes easier for listeners to navigate through the audiobook.

    What is the magic command line that would do this ?

    Thank you very much !

  • How to use ffmpeg with h.265 (or h.264) coded ?

    8 mai 2015, par randomuser1

    Normally I start recording the camera image with the command :

    ffmpeg -y -f vfwcap -r 25 -i 0 OUT.mp4

    but I’m not sure which coded do I use in here (I’m just beginning my adventure with ffmpeg), however I found on this webpage this command :

    ffmpeg -i INPUT -c:a copy -x265-params crf=25 OUT.mov

    But when I run it - I get the following error :
    INPUT: No such file or directory"

    I changed the INPUT word above also to 0, so the command is

    ffmpeg -i 0 -c:a copy -x265-params crf=25 OUT.mov,
    but error stays similar (0: no such file or directory).
    How can I grab the camera image and save it to a file while using the H.265 ?
