  4 août 2020, par yejafot

  why im getting the below errors.
Am i done any misconfiguration in the build file ?

  


  Can you change it according, im trying to configure for arm64_v8a (.so) file for android jni in my linux machine. Thanks !

  


  Below is my build file.

• Incorrect Codec Parameters, Could not write header for output file : FFMPEG - Android

  26 septembre 2016, par Salmaan

  Why do I get Incorrect Codec Parameters....???
  I am creating video using Android MediaRecorder, use FFMPEG over it to trim it.
  I am just trying to trim the video using FFMPEG.

  String[] ffmpegCommand = {
  
                      "/data/data/uk.org.humanfocus.hfi/ffmpeg",
  
                       "-ss",
  
                       "00:00:00",
  
                       "-i",
  
                       path,  // string variable, path of file
  
                       "-t",
  
                       "00:00:05", // duration of video
  
                       "-c",
  
                       "copy",
  
                       destination + "/trimmmmm.mp4" }; // string

  This is log I get..
  It is from starting of FFMPEG processing until it ends.

• Android : Pass video path to FFmpeg

  29 septembre 2020, par marian

  I have developed an app that play video from gallery. I would like to add watermark using FFmpeg command in the video selected. But I do not know how to pass the path to the FFmpeg command. I could not find proper tutorials or reference regarding this. My coding are as follows :

  


  MainActivity.java :

  


  public class MainActivity extends Activity {
public ProgressDialog progressBar;

String workFolder = null;
String demoVideoFolder = null;
String demoVideoPath = null;
String vkLogPath = null;
LoadJNI vk;
private final int STOP_TRANSCODING_MSG = -1;
private final int FINISHED_TRANSCODING_MSG = 0;
private boolean commandValidationFailedFlag = false;

Button button;
VideoView videoView;
private static final int PICK_FROM_GALLERY = 1;


private void runTranscodingUsingLoader() {
    Log.i(Prefs.TAG, "runTranscodingUsingLoader started...");

    PowerManager powerManager = (PowerManager)MainActivity.this.getSystemService(Activity.POWER_SERVICE);
    PowerManager.WakeLock wakeLock = powerManager.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "VK_LOCK");
    Log.d(Prefs.TAG, "Acquire wake lock");
    wakeLock.acquire();

    

    String[] complexCommand = {"ffmpeg","-y" ,"-i", "/sdcard/videokit/in.mp4","-strict","experimental",
            "-vf", "movie=/sdcard/videokit/watermark.png [watermark];" +
            " [in][watermark] overlay=main_w-overlay_w-10:10 [out]","-s",
            "320x240","-r", "30", "-b", "15496k", "-vcodec", "mpeg4","-ab",
            "48000", "-ac", "2", "-ar", "22050", "/sdcard/videokit/out1.mp4"};

  FFmpeg command :

  


  String[] complexCommand = {"ffmpeg","-y" ,"-i",  "/sdcard/videokit/in.mp4","-strict","experimental",
            "-vf", "movie=/sdcard/videokit/watermark.png [watermark];" +
            " [in][watermark] overlay=main_w-overlay_w-10:10 [out]","-s",
            "320x240","-r", "30", "-b", "15496k", "-vcodec", "mpeg4","-ab",
            "48000", "-ac", "2", "-ar", "22050", "/sdcard/videokit/out1.mp4"};


  


  Tis command is from a sample project. How do I pass the video path to this command ? I do not know how to edit the command to support my requirement. Can someone guide me through this. Any help will be really helpful. Thank you.
