  • optimizing ffmpeg in windows platform for processing with web-cam

    22 août 2013, par user2320537

    I have to develop a tool in java that will capture frames from webcam, Now what I have done for that is, I have used Runtime class to run ffmpeg and other commands, when it starts capturing frames from my web-cam,
    I am using following method for that.

    public class FFMPEGClass {
    

    
    private String ffmpegExeLocation, line;
    
    private final String FRAME_DIGITS = "010";
    

    
    public FFMPEGClass(String capturingDName, String outputImagesLocation, int framesPerSecond) {
    
        ffmpegExeLocation = System.getProperty("user.dir") + "\\bin\\";
    
        System.out.println(ffmpegExeLocation);
    
        try {            
    
            System.out.println(ffmpegExeLocation + "ffmpeg -t 100000 "
    
                    + "-f vfwcap -s 640x480 -i 0 -r 1/" + framesPerSecond + " -f image2 " + outputImagesLocation + "\\camera%"+FRAME_DIGITS+"d.jpg");
    
            Process pp = Runtime.getRuntime().exec(ffmpegExeLocation + "ffmpeg -t 100000 "
    
                    + "-f vfwcap -s 640x480 -i 0 -r 1/" + framesPerSecond + " -f image2 " + outputImagesLocation + "\\camera%"+FRAME_DIGITS+"d.jpg");
    
            BufferedReader br = new BufferedReader(new InputStreamReader(pp.getErrorStream()));
    
            while((line = br.readLine()) != null){
    
                 System.out.println(line);
    
            }
    
        } catch (Exception ex) {
    
            ex.printStackTrace();
    
        }
    
    }
    
}

    In my case capturingDName is USB2.0 UVC VGA WebCam
    outputImagesLocation is e :\myfolder\frames and
    framesPerSecond is 10

    This code works well but it is unable to capture frames efficiently, In other words I want to say that its processing is very slow, can anyone please tell that how can I optimize it so that it can capture frames very fastly.

    I have Intel Core i3 processor with 6 GB of RAM

    I have already checked many answers from google and stackoverflow but these are not working in my case

  • Use Adobe After Effects scripts in a web app

    13 mars 2015, par user3767323

    I have a bunch of After Effects files with some scripts - mostly transition effects for a slideshow. Is there a way to reuse them in a custom web app with a linux-based rendering engine (FFMPEG, MLT).

  • ffmpeg not capturing frames in windows using java

    19 août 2013, par user2320537

    I have to develop a tool in java that will capture frames from webcam, Now what I have done for that is, I have used Runtime class to run ffmpeg and other commands, when it opens web-cam then after sometime my web-cam hangs and it does not capture frames.

    I am using following method for that.

    public class FFMPEGClass {
    

    
    private String ffmpegExeLocation;
    
    private final String FRAME_DIGITS = "010";
    

    
    public FFMPEGClass(String capturingDName, String outputImagesLocation, int framesPerSecond) {
    
        ffmpegExeLocation = System.getProperty("user.dir") + "\\bin\\";
    
        System.out.println(ffmpegExeLocation);
    
        try {
    
            System.out.println(ffmpegExeLocation + "ffplay -f dshow -video_size 640x480 -i video=\"" + capturingDName + "\"");
    
            Runtime.getRuntime().exec(ffmpegExeLocation + "ffplay -f dshow -video_size 640x480 -i video=\"" + capturingDName + "\"");
    
            System.out.println(ffmpegExeLocation + "ffmpeg -t 100000 "
    
                    + "-f vfwcap -s 640x480 -i 0 -r 1/" + framesPerSecond + " -f image2 " + outputImagesLocation + "\\camera%"+FRAME_DIGITS+"d.jpg");
    
            Runtime.getRuntime().exec(ffmpegExeLocation + "ffmpeg -t 100000 "
    
                    + "-f vfwcap -s 640x480 -i 0 -r 1/" + framesPerSecond + " -f image2 " + outputImagesLocation + "\\camera%"+FRAME_DIGITS+"d.jpg");
    
        } catch (Exception ex) {
    
            ex.printStackTrace();
    
        }
    
    }
    
}

    In my case capturingDName is USB2.0 UVC VGA WebCam
    outputImagesLocation is d :\frames and
    framesPerSecond is 16

    For a moment if i run these commands in command prompt then also I am unable to capture frames.

    I have already checked many answers from google and stackoverflow but these are not working in my case
