• ffmpeg commands execution failed when run from Java. Executed successfully when the command is run in the terminal

  28 septembre 2022, par Kaung Myat Khaing

  I'm working on a java project which works with audio file manipulation(I'm newbie to Java). I want to get the start and end time of silence in the audio with ffmpeg "silencedetect" audio filter and write the results to a text file.
I run the filter command within the following function, but it always result in failure(prints "Silence Detection failed"). Then, I tried running the command in the terminal and it was successful(prints "Silence Detection successful"). I don't know what's wrong with my java code. I have other functions which execute other ffmpeg commands with the same flow as provided, but they works fine.
Here's the function.

  


  public static void getSilence(String filePath) throws InterruptedException, IOException {
        //                detect silence
        System.out.println("Silence Detection cmd: ffmpeg -i " + filePath
                + " -af silencedetect=d=1:noise=-60dB -f null - |& awk '/silencedetect/ {print $4,$5}' > "
                + SOURCE_PATH + "/silence_detections/silenceInfo.txt");
        Process silenceDetect = Runtime.getRuntime().exec("ffmpeg -i " + filePath
                + " -af silencedetect=d=1:noise=-60dB -f null - |& awk '/silencedetect/ {print $4,$5}' > "
                + SOURCE_PATH + "/silence_detections/silenceInfo.txt");

        if (silenceDetect.waitFor() == 0) {
            System.out.println("Silence Detection successful");
        } else System.out.println("Silence Detection failed");
    }


  


• Can no longer get ffmpeg to run in Terminal on macOS

  31 décembre 2023, par Chewie The Chorkie

  Here's a command I tried to run which always worked :

  


  Mac-mini:images Admin$ ffmpeg -r 30  -f image2 -s 1080x1080 -i %d.png -vcodec h264 -crf 25  -pix_fmt yuv420p zVideo.mp4


  


  The output I get is :

  I've tried reinstalling ffmpeg, installing the command line tools from Xcode, and Xcode itself.

  


• Terminal command to upgrade FFMPEG

  14 avril 2023, par Savvy Turtle

  Everything is still installed but once I upgraded my server from CentOS 7.6 to Cloud Linux FFMPEG does not seem to work anymore.

  


  When I go and debug it in the admin section where you upload a test video and hit debug it shows a toast to upload a video. and on the front end of https://turtle.tube/ users upload a video and it gets stuck at 100% upload and processed.

  


  So I'm wondering whether I need to ugrade FFMPEG to work with Cloud Linux update or If I need to restart it.

  


  Any help would be great thanks.

  Checked Version, looked for terminal command to upgrade FFMPEG to latest stable release of : FFmpeg 5.1.3 "Riemann" or FFmpeg 6.0 "Von Neumann" but have not figured out the command to upgrade yet.

  


  nor the command to restart FFMPEG if that even exist.

  


  Current version of FFMPEG shows :

  


  ffmpeg -version
