• How to combine multiple videos in android using ffmpeg ?

  23 mai 2023, par Haeiny

  I added dependency to use ffmpeg on Android.

  


  implementation "com.arthenica:mobile-ffmpeg-full:4.4"


  


  And I wanted to combine the videos from the gallery, so I temporarily saved the imported video in the cache directory in the app.

  


  After that, I wrote the following function to take the saved images and merge them using ffmpeg :

  


  
fun mergeVideos(videoPaths: List\): Int {
        val cacheDirectory = this.externalCacheDir
        mergedVideoFile = File(cacheDirectory, "merged_video.mp4").absolutePath

        val command = StringBuilder()
        command.append("ffmpeg")
        for (videoPath in videoPaths) {
            command.append(" -i ").append(videoPath)
        }

        command.append(" -filter_complex ").append("\"")
        for (i in videoPaths.indices) {
            command.append("[$i:v] ").append("[$i:a] ")
        }

        command.append("concat=n=").append(videoPaths.size).append(":v=1:a=1 [v] [a]").append("\"")
        command.append(" -map \"[v]\" -map \"[a]\" ").append(mergedVideoFile)
    
        return FFmpeg.execute(command.toString())
    }


  


  I wanted to temporarily save the merged video in the "mergedVideoFile" so that I could save them in the cache directory, and videoPaths would get the Urls of the videos I wanted to merge into the list.

  


  The command verified through Log.d :

  


  
ffmpeg -i /storage/emulated/0/Android/data/"project name"/files/Movies/VIDEO1.mp4 -i /storage/emulated/0/Android/data/"project name"/files/Movies/VIDEO2.mp4 -filter_complex "\[0:v\] \[0:a\] \[1:v\] \[1:a\] concat=n=2:v=1:a=1 \[v\] \[a\]" -map "\[v\]" -map "\[a\]" /storage/emulated/0/Android/data/"project name"/cache/merged_video.mp4

• FFmpeg Android Errors

  17 février, par axjp

  Ok so im making a kotlin android app and for file conversion from 3gp to wav i added the android ffmpeg library with implementation 'com.arthenica:mobile-ffmpeg-full:4.4' then i added this code to convert the files FFmpeg.execute("-i" + f2 +"/storage/emulated/0/Android/data/com.icompilecodewithnowarnings.ffmpegthing/files/Documents/recording.wav") for further context f2 is /storage/emulated/0/Android/data/com.icompilecodewithnowarnings.ffmpegthing/files/Documents/recording.3gp

  


  The error log is to large to simply just fit here but heres some of it

  


  Execution failed for task ':app:checkDebugAarMetadata'.

  Caused by: org.gradle.internal.resolve.ModuleVersionNotFoundException: Could not find com.github.hiteshsondhi88.libffmpeg:FFmpegAndroid:0.3.2.


  


  I tried to compile however the compiler immediatley rejected my app and refused to compile. I would have expected it to have immidiatley compiled into a apk.
