• Merge mp3 files at specific duration in Android

  18 mai 2017, par Gio Vanno

  First I’m new in Android.

  I’m trying to make an app that can combine a lot of music(mp3 files im using) at specific duration with the selected music via seekbar.

  My main plan is to merge multiple audio files at specific time.

  example :
  when i pressed the drum button at 5 sec(via seekbar), and then guitar button at 6 sec.

  when i clicked the merge button, it will merged the selected mp3 file with those 2 mp3 files at their respective time.

  from what i’m searching so far, the possible way is by using ffmpeg from this :

  -How to overlay two audio files using ffmpeg

  -Merge mp3 files using FFmpeg on Android

  but i don’t see them merged at specified time.

  maybe there’s another way besides ffmpeg,or i’ve missed something ?

  thank you

• Integrating FFMpeg in Native Android Application with C++ results in bunch of errors [closed]

  13 décembre 2024, par BraveEvidence

  I need to integrate ffmpeg in my android app, i don't want to usee ffmpegkit as that is not properly maintained, i cloned ffmpeg-android-maker and then ran ./ffmpeg-android-maker.sh it created build folder and output folder,
The output folder looks like this

  


  

  


  I have created a kotlin android project using android studio, so i have written all the code to pick the video and i have the video uri with me in kotlin, i also added a C++ module with help of Android studio and it did all the configuration in build.gradle and also created CMake file for me.

  


  For now I just want to concentrate on building the android project so forget about writing any C++ code, I then created jniLibs in main folder and in jniLibs I copied arm64-v8a,armeabi-v7a, x86,x86_64 from the output folder of ffmpeg-android-maker and then I want to cpp folder of my android project which is also in main folder and in cpp folder I created include folder and copied libavcodec, libavdevice, libavfilter etc then I updated my CmakeLists.txt to following

  


  cmake_minimum_required(VERSION 3.22.1)

project("myandroidapp")

#set(FFMPEG_LIBS_DIR ${CMAKE_SOURCE_DIR}/src/main/jniLibs)

include_directories(${CMAKE_SOURCE_DIR}/src/main/cpp/include)

set_target_properties(${CMAKE_PROJECT_NAME} PROPERTIES
        LIBRARY_OUTPUT_DIRECTORY ${CMAKE_SOURCE_DIR}/src/main/jniLibs/${ANDROID_ABI}
)

add_library(${CMAKE_PROJECT_NAME} SHARED
    # List C/C++ source files with relative paths to this CMakeLists.txt.
    myandroidapp.cpp)


# Specifies libraries CMake should link to your target library. You
# can link libraries from various origins, such as libraries defined in this
# build script, prebuilt third-party libraries, or Android system libraries.
target_link_libraries(${CMAKE_PROJECT_NAME}
    # List libraries link to the target library
    android
    log
        avcodec
        avdevice
        avfilter
        avformat
        avutil
        swresample
        swscale)


  


  Then in build.gradle I did following

  


  externalNativeBuild {
        cmake {
            path = file("src/main/cpp/CMakeLists.txt")
            version = "3.22.1"
        }
    }

    sourceSets {
        getByName("main") {
            jniLibs.srcDirs("src/main/jniLibs")
        }
    }

    packaging {
        jniLibs.pickFirsts.add("lib/arm64-v8a/libavcodec.so")
        jniLibs.pickFirsts.add("lib/arm64-v8a/libavformat.so")
        jniLibs.pickFirsts.add("lib/arm64-v8a/libavutil.so")
        jniLibs.pickFirsts.add("lib/arm64-v8a/libswscale.so")
        jniLibs.pickFirsts.add("lib/armeabi-v7a/libavcodec.so")
        jniLibs.pickFirsts.add("lib/armeabi-v7a/libavformat.so")
        jniLibs.pickFirsts.add("lib/armeabi-v7a/libavutil.so")
        jniLibs.pickFirsts.add("lib/armeabi-v7a/libswscale.so")
        jniLibs.pickFirsts.add("lib/x86/libavcodec.so")
        jniLibs.pickFirsts.add("lib/x86/libavformat.so")
        jniLibs.pickFirsts.add("lib/x86/libavutil.so")
        jniLibs.pickFirsts.add("lib/x86/libswscale.so")
        jniLibs.pickFirsts.add("lib/x86_64/libavcodec.so")
        jniLibs.pickFirsts.add("lib/x86_64/libavformat.so")
        jniLibs.pickFirsts.add("lib/x86_64/libavutil.so")
        jniLibs.pickFirsts.add("lib/x86_64/libswscale.so")
    }


  


  when I try to build my project I get following error

• Converting konvajs state to Advanced SubStation Alpha (ASS) format for subtitles

  7 juillet 2024, par Ahsan

  I am building a subtitle editor using react.js. I plan to use konvajs to build the styling feature of editor like rotate subtitles, change size etc. How do I convert resultant konva state to ass format so that ffmpeg can render these subtitles on video.

  


  If there is a better solution than using konvajs then please guide me.
