  • 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.

  • What's the ideal encoding for rendering an immediate video (e.g. preview) while waiting for the high-quality video to render ? [on hold]

    20 avril 2018, par allanbreyes

    I’m working on an application that renders an MLT (OSS non-linear video-editing engine) project on a web server, which uses ffmpeg under the hood. While waiting for the high-quality render to finish (several minutes), I need to make a "best-effort" render in parallel so that users can immediately (i.e. real-time) see the results. What encoding works best for this ?

  • FFmpeg on windows 7, encode video in mp4 for HTML 5 video fail

    14 avril 2013, par manonthemoon

    I try to encode my video with FFmpeg, to convert to mp4.
    But the video doesn't work on html 5. I don't understand why.

    I found this command on the web and I tried it :

    ffmpeg.exe -i wildlife.wmv -b 1500k -vpre slow -vpre baseline -vcode libx264 \
  -g 30 wildlife.mp4

    But it fails, and I have this error :

    File for preset 'slow' not found

    I check the folder "presets" and the preset is on the folder, so I don't understand why it's telling me this error.
    I tried with the complete path, it fails too.
