  • IOException when I use Runtime for FFMPEG [duplicate]

    20 octobre 2016, par Kilobyte

    This question already has an answer here :

    I’m trying to write a java program that converts a video file (mp4) into an audio file (mp3) using FFMPEG, but I have an IOException.
    Is there something wrong in my code ?

    import java.lang.Runtime;
    

    
public class Basketball {
    

    
/**
    
 * @param args the command line arguments
    
 */
    
public static void main(String[] args) {
    
    Process p = Runtime.getRuntime().exec("ffmpeg highlightsCLGS.mp4 -vn -ab 256 highlightsOutput.mp3");
    
}
    
}

    And this is the error.

    Exception in thread "main" java.lang.RuntimeException: Uncompilable source code - unreported exception java.io.IOException; must be caught or declared to be thrown

  • using ffmpeg.js to play H265 video, only play hvc1 format, can't play hev1 format, is there anyway to play hev1 ?

    1er novembre 2019, par Alex

    I compiled ffmpeg into ffmpeg.js and ffmpeg.wasm by using emscripten, so that it can run in the browser and play H265 video.

    However, I found that only the hvc1 format can be played.
    Like that：

    Stream #0:0(und): Video: hevc (Main) (hvc1 / 0x31637668), yuv420p(tv, bt709, progressive), 1280x720, 854 kb/s, 25 fps, 25 tbr, 12800 tbn, 25 tbc (default)

    and the hev1 format cannot be played.Like that :

    Stream #0:0(und): Video: hevc (Main) (hev1 / 0x31766568), yuv420p(tv, progressive), 1920x1080 [SAR 1:1 DAR 16:9], 829 kb/s, 25 fps, 25 tbr, 12800 tbn, 25 tbc (default)

    Web browser’s Console has this errors

    ffplay can play these two, why can only play hvc1 after compiling into ffmpeg.js and ffmpeg.wasm ?

  • How to detect a surge of activity in a video ?

    22 mars 2019, par Alain Collins

    I’d like to automatically detect a surge of activity in a video, e.g. basketball jump shot, hockey face-off, sprinters starting, etc., preferably using ffmpeg.

    In these instances, there’s some motion as the players assume their positions, followed by a pause as they wait for the ref to throw the ball or drop the puck, followed by a lot of motion as all players begin to react. It’s also typical that the camera will be still during this period and begin moving as the ball or puck changes position.

    I’ve tried using the ’select’ filter select='gt(scene,0.4)', but that seems to be more concerned with scene changes (i.e., more dramatic changes) even with low thresholds.

    I also tried exporting the scene information and examining it manually, but couldn’t find a clear pattern that correlated with motion in the video.

    UPDATE : I ran a mestimate on the video. Processing took a long time, but there was definitely a change in activity before and at point of interest. Is there a way to export this information to a file, or otherwise detect the amount of motion seen my mestimate ?
