  • FFmpeg : calculate time to convert images and .mp3 to a video

    6 avril 2013, par DomenK

    Is there any formula that I can use to calculate the time that FFmpeg uses to convert a single .jpg image and .mp3 song to a video ?

    I am using the following code :

    ffmpeg -loop 1 -r ntsc -i image.jpg -i song.mp3 -c:a copy -c:v libx264 \
  -preset fast -threads 0 -shortest

    Lets say we have an image with X resolution and .mp3 length of L. Would the formula be :

    time = X * L(in seconds) ?

    Thanks for any tips.

  • More efficient way to read out certain video frames

    2 juin 2018, par Kaskorian

    Is there a more efficient way to read out certain frames of a video (for example the 30th frame) than the way shown below ?

    using AForge.Video.FFMPEG;
    

    
private Bitmap GetThumbnail(string path, int frame)
    
{
    
    VideoFileReader reader = new VideoFileReader();
    
    reader.Open(path);
    

    
    for (int i = 1; i < frame; i++)
    
        reader.ReadVideoFrame();
    

    
    return reader.ReadVideoFrame();
    
}

    The problem here is that you have to read out all the previous frames as well. So to read out the 30th frame you really have to read 30 frames and not the just the 30th.

    Any ideas for other ways that are far more efficient ?

  • Heroku ffmpeg buildpack

    20 octobre 2015, par Manuel Quintanilla

    Putting together the video upload section in my rails app and am having some issues with video play on mobile phones. Im using

    paperclip-av-transcoder, s3 and  Heroku

    On my laptop I can visit the page and see the video thumbnails and play the videos only because I have previously installed ffmpeg to my machine.

    Remotely on Heroku I’ve set the appropriate buildpacks for ffmpeg and have run push heroku master to install the buildpacks - Now when I visit the page on my mobile iPhone I don’t get a thumbnail but when I play the video it plays - on the other hand when I visit the page on my Android phone I don’t get a thumbnail and the video dose not play but I can upload mp4s on Android.

    Check out my set up here : Heroku ffmpeg buildpacks for video uploads

    It seems I don’t have the proper buildpack setup or some other heroku setting with ffmpeg.

    Any suggestions ? Thanks in advance !
