• Is anyone willing to join a GTK+3 project started in 2009 and still active ?

  15 mars 2020, par GiuTor

  first of all if my question is not relevant to stackoverflow website please delete it, I apologize in advance.

  I started Imagination, a DVD slideshow maker developed with GTK+2 in 2009. Along the years users have contributed with few patches. The software was ported to GTK+3 last year. Imagination works by using Cairo to paint the transition on a GTK drawing area and ffmpeg run in the background to encode the video. I’m currently getting rid of ffmpeg and using libav to encode the video.

  Does anybody want to help with libav coding ? The software is available through SVN :

  svn co https://svn.code.sf.net/p/imagination/code/trunk imagination

  The web site is hosted at sourceforge : http://imagination.sourceforge.net/

  Thanks :)

• How to import FFmpeg into Android project

  3 août 2023, par Vyacheslav Parinov

  I'm trying to convert series of images into video.
For that I'm adding FFmpeg into my Android project.
However it is not adding properly, so I can't import class FFmpeg into the code.
in the statement "int rc = FFmpeg.execute(command) ;" FFmpeg is highlighted in red.

  


  I think something wrong with libraries. Could you please give suggestion how import libraries correctly ?

  


  My Manifest file below

  


  <?xml version="1.0" encoding="utf-8"?>


  


  


  &#xA;&#xA;&#xA;&#xA;    &#xA;        &#xA;            <action></action>&#xA;&#xA;            <category></category>&#xA;        &#xA;    &#xA;&#xA;

  



  My settings.gradle file

  


  pluginManagement {
repositories {
    google()
    mavenCentral()
    gradlePluginPortal()
}


  


  


  dependencyResolutionManagement {
repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
repositories {
    google()
    mavenCentral()
}


  


  
rootProject.name = "TimelapseLite"
include ':app'

  


  My build.gradle file

  


  plugins {
    id 'com.android.application'

android {
    namespace 'ae.vpdev.timelapselite'
    compileSdk 33

defaultConfig {
    applicationId "ae.vpdev.timelapselite"
    minSdk 26
    targetSdk 33
    versionCode 1
    versionName "1.0"

    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"

    }
}
compileOptions {

        writer.flush();
        writer.close();

        File outputFile = new File(getExternalFilesDir(null), "output_video.mp4");
        String outputFilePath = outputFile.getAbsolutePath();

        String command = "-f concat -safe 0 -i " + imageListFile.getAbsolutePath() +
                " -vf \"scale=-2:720\" -r 30 -c:v libx264 -pix_fmt yuv420p " + outputFilePath;

        int rc = FFmpeg.execute(command);

        if (rc == RETURN_CODE_SUCCESS) {
            Log.d("FFmpeg", "Video conversion completed successfully");
            // Now you can use the outputFilePath to play or share the video
