  • How to generating waveform from video & show it with video

    25 novembre 2016, par Salil

    We are using Rails as a backend & AngularJS on Front End side in my App where we need to show Video & audio waveform of that video.

    We are using ’wavesurfer.js’ to show the waveform on Front End side & ’node-pcm’ to generate pcm from video file on BackEnd side.

    This is working as expected but in some of the videos while creating waveform from pcm data instead of showing small sine waves we get flat line.
    Also it takes too much time to show the waveform for every page reload.

    To overcome this issue we are planning to create waveform image using ffmpeg

    ffmpeg -i 'https://s3.amazonaws.com/aadasdsadsadasdas/xyz.mp4' -filter_complex showwavespic -frames:v 1 output.png

    This is working fine but it also takes too much time (Ofcourse only once ) to generate the image for remote video (i.e. We are saving videos on S3)

    Problem with this i don’t get any library to integrate the waveform image with the Video.

    Can someone suggest any better approach related to this.

  • ffmpeg x11grab inputting improperly

    20 décembre 2017, par Not a superuser

    I have the stock ffmpeg install from the xbps repository. I’ve used it before, but am on a new system.

    Running "ffmpeg x11grab -video_size 1280x800 -framerate 60 -i $DISPLAY output.mkv" yeilds no errors, but when I watch the video it is a mess switching between workspaces and with only partly rendered programs.

    Taking other inputs such as webcam work fine, and different encoding methods don’t change anything (though webm flat out doesn’t work, but that’s not a problem for me).

    I’ve tried what’s here : https://wiki.archlinux.org/index.php/FFmpeg

    Only other thing to note is that I use i3 as a dm, which shouldn’t be a problem, but figured I’d state it just in case.

    EDIT :
    I was using compton for composite, and that was where my issue lied...

  • avfilter/framesync : fix forward EOF pts

    4 octobre 2024, par Nicolas Gaullier
    avfilter/framesync : fix forward EOF pts

    Note1 : when the EOF pts is not accurate enough, the last frame
    
can be dropped by vf_fps with default rounding.
    

    Note2 : vf_scale use framesync since e82a3997cdd6c0894869b33ba42430ac3,
    
so this is a very commonplace scenario.
    

    For example :
    
./ffprobe -f lavfi testsrc=d=1,scale,fps -of flat \
    
  -count_frames -show_entries stream=nb_read_frames
    

    Before :
    
streams.stream.0.nb_read_frames="24"
    

    After :
    
streams.stream.0.nb_read_frames="25"
