I am converting images to video using ffmpeg in koltin but i am getting error
28 mars 2024, par Mohith_karthikeyai implement ffmpeg by using this gitbub by this reference :5

https://github.com/tanersener/mobile-ffmpeg
in koltin
my code is :

class BurstModeToVideo(
 private val context: Context,
 private val onVideoConverted: (File) -> Unit
) {

 private val vibeDirectory = File(context.getExternalFilesDir(Environment.DIRECTORY_PICTURES), "vibes")
 private val outputDirectory = context.getExternalFilesDir(Environment.DIRECTORY_MOVIES)

 fun convertBitmapToJpeg(vibes: List<bitmap>) {
 if (!vibeDirectory.exists()) {
 vibeDirectory.mkdirs()
 }

 vibes.forEachIndexed { index, vibe ->
 val fileName = "$index.jpg"
 val file = File(vibeDirectory, fileName)
 FileOutputStream(file).use { fos ->
 vibe.compress(Bitmap.CompressFormat.JPEG, 100, fos)
 }
 }
 }

 private val callback = ExecuteCallback { _, returnCode ->
 if (returnCode == Config.RETURN_CODE_SUCCESS) {
 try {
 val tempFile = File("${outputDirectory?.absolutePath}/vibe.mp4")
 onVideoConverted(tempFile)
 Log.e(TAG, "FFmpeg output found $tempFile")
 Toast.makeText(context,"$tempFile",Toast.LENGTH_LONG).show()
 Log.e(TAG, "FFmpeg output found $")
 } catch (e: IOException) {
 Log.e(TAG, "Error handling FFmpeg output", e)
 }
 } else {
 Log.i(TAG, "Async command execution failed with returnCode=$returnCode.")
 }
 }

 fun convertShotsToVideo() {
 if (!vibeDirectory.exists() || vibeDirectory.listFiles()?.isEmpty() == true) {
 Log.e(TAG, "No images to convert")
 return
 }

 Log.d(TAG, "Images are stored in: ${vibeDirectory.absolutePath}")

 val imageFiles = vibeDirectory.listFiles { file -> file.isFile && file.extension.equals("jpg", ignoreCase = true) }
 if (imageFiles.isNullOrEmpty()) {
 Log.e(TAG, "No image files found in directory")
 return
 }

 Log.d(TAG, "List of image files:")
 imageFiles.forEach { file ->
 Log.d(TAG, file.name)
 }

 val cmd = "-i ${vibeDirectory.absolutePath}/%d.jpg -c:v mpeg4 -y ${outputDirectory?.absolutePath}/vibe.mp4"

 FFmpevubeg.executeAsync(cmd, callback)
 }

 companion object {
 private const val TAG = "BurstModeToVideo"
 }
}
</bitmap>


above function convert images from bimtap to jpeg files and then it converts to video by using ffmpeg. And i initialize this fun in mainactivity.kt and it goes here :


var vibe by remember {
 mutableStateOf(null)
 }

 val burstModeToVideo = BurstModeToVideo(
 context,
 onVideoConverted = {
 vibe = it
 }
 )
coroutineScope.launch {
 withContext(Dispatchers.IO) {
 burstModeToVideo.convertBitmapToJpeg(vibesList)
 burstModeToVideo.convertShotsToVideo()
 }
 }

VideoPlayer(vibe)



now this vibe variable is used in videoPlayer function and it goes here :


@OptIn(UnstableApi::class)
@Composable
fun VideoPlayer(file: File) {
 val context = LocalContext.current

 val exoPlayer = remember {
 ExoPlayer.Builder(context)
 .build()
 .apply {
 val defaultDataSourceFactory = DefaultDataSource.Factory(context)
 val dataSourceFactory: DataSource.Factory = DefaultDataSource.Factory(
 context,
 defaultDataSourceFactory
 )
 this.repeatMode = ExoPlayer.REPEAT_MODE_ALL
 this.playWhenReady = true
 val source = file.let {
 ProgressiveMediaSource.Factory(dataSourceFactory)
 .createMediaSource(MediaItem.fromUri(Uri.fromFile(file)))
 }
 this.setMediaSource(source)
 this.prepare()
 this.play()
 this.volume = 0f
 }
 }

 DisposableEffect(Unit) {
 onDispose {
 exoPlayer.release()
 }
 }

 AndroidView(
 factory = { ctx ->
 PlayerView(ctx).apply {
 useController = false
 resizeMode = AspectRatioFrameLayout.RESIZE_MODE_ZOOM
 player = exoPlayer
 }
 },
 modifier = Modifier.fillMaxSize()
 )
}



the error is :

Reduce ffmpeg CPU usage with h265 [closed]
23 septembre 2024, par NeskelogthI have a video file to convert using
ffmpeg
on Ubuntu 22.04. The input uses the codech264
and I want to convert it toh265
(mainly for storage capacity reasons). The output offfmpeg -version
is

I saw online that one of the options of
ffmpeg
is-threads
, but apparently it does not work, since usingffmpeg -i input.mp4 -c:v libx265 -c:a copy output.mp4
andffmpeg -i input.mp4 -c:v libx265 -c:a copy -threads 2 output.mp4
seem to be exactly the same in terms of CPU usage as shown byhtop
. Is there something wrong in my usage of-threads
?
