  • FFMPEG - How to Extract Frames As Images While Removing Sequentially Duplicate Frames

    19 mars 2017, par Michael Nelson

    Is there any way (via script or preferably some parameter in calling ffmpeg that I missed) to extract frames from an avi file and ignore sequentially duplicate frames, thus being able to go through the pictures looking only at the deltas/changes ?

    I frequently have to record meetings at work and a lot of the time, the client screen that I am looking at is not changing while we are talking over the phone. After the meeting is over, I need to use these images as part of our documentation and specifications gathering.

    I know that I could just output every frame and run them through any given duplicate file remover utility, but this would remove ALL duplicate frames. So, if the frames extracted went like this :

    A, A, A, B, B, B, B, C, C, A, A, C, C, C, B, B, B ...

    Running them through a typical duplicate file remover, I would get : A, B, C

    What I would want is : A, B, C, A, C, B

    The command that I am currently using to extract the images is :

    ffmpeg.exe -i file.avi -ss 0 -sameq -f image2 -r 1 images%5d.png

    I was getting every frame beforehand (removing the -r 1 from above), but that was generating way too many frames to deal with since these online meetings can go for hours, so for now, I get one frame per second from the file.

    A Windows based solution would be preferable, however, I’m sure other people would be interested in solutions on other platforms if available.

    Any solution or point in the right direction is much appreciated.

  • Web audio stream

    21 février 2013, par user658091

    What's a good solution for web audio streaming ?

    I've read about Flash Media Server, but that's a little too expensive right now, it seems easier than other solutions but can't afford it.

    There is FFmpeg, FFserver, Icecast and SSH among the popular.

    What I want is an easy solution for the user, which I was thinking something with flash. Load up FFmpeg/FFserver or Icecast as server stream and read that stream with a flash player inside the webpage. (I don't want to force users to download VLC or winamp)

    I'm not sure if I'm going the right way.

  • ffmpeg C api capture frames from usb Cam

    18 février 2013, par Ahmed Kato

    After doing some search I can find some command line solutions to grab frames from the webcam like this :

    ffmpeg -ss 60 -i input.mpg -frames:v 20 frame_%d.png

    but I need to do that usgin the ffmpeg C api, this tutorial is outdated.

    at the end my question is how to grab frames from a webcam using ffmpeg C api.
