FFMPEG - copy the SPECIFED tracks only, ignore all others
10 janvier 2024, par GDPI have some very strange MP4 files that we get regularly for processing created by Wowza. Neither FFMPEG or MEDIAINFO can detect that there are subtitles soft-coded in them, but they ARE there, I can extract them with ccextractor, and when they're played, the captions appear later in the video where the actually start in the timeline.


I've tried every variation of copying with/without re-encoding, but all the answers show how to "omit" the subtitles with -sn such as these :


ffmpeg -i 3078.mp4 -c copy -sn 3078_sn.mp4
 ffmpeg -i 3078.mp4 -c:v libx264 -c:a ac3 -map 0:v:0 -map 0:a:1 3078_sn.mp4
 ffmpeg -i 3078.mp4 -map 0:v:0 -map 0:a:0 -map -0:s -map -0:d -c copy 3078_sn2.mp4 -y


FFprobe :

The problem seems to be that FFMPEG isn't detecting they're there, and so copies them anyways. My assumption is that they're not stored in the header of the MP4 properly (or however that's done), so get because they're later detect, but weren't omitted when it checked the header (pure guesswork on that).


So, is there a way to copy ONLY the video, regardless of whatEVER tracks may or not be in the file, then do the same for audio, and then merge the two single-track files ?

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-ffmpegin 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 :

Unable to stream video file from MediaMTX media server to browser via WebRTC
8 juin 2024, par thegreatjediI took over a repository at work. It's a working demo comprising a web server which receives video and camera feeds from a media server (built from the rtsp-simple-server Docker image) via a RTSP relay server and streams the feeds to the client, all deployed via Docker Compose.


I'm trying to switch over to use WebRTC instead. rtsp-simple-server has upgraded into MediaMTX since the time the demo was created 2 years ago. This is the relevant section of the updated Docker Compose configuration :


media-server:
 image: bluenviron/mediamtx:latest-ffmpeg

 # Settings under path "all_others" are applied to all paths that

I've absolutely no experience with WebRTC. This is my first time hearing of this protocol, let alone working with it. From what I understand, I need to convert my demo mp4 videos (which were successfully streaming via RTSP in the previous implementation) to a compatible video codec, so I've opted for VP8.


Before trying to stream the videos into my web server, I tested the stream directly in the browser (tried with both the latest versions of Chrome and Edge). I went to
http://localhost:8889/demo0(which should convert demo0.mp4 to VP8 and then stream it over WebRTC). The video player loaded in the browser but no video data was received and nothing played. After several seconds, the screen displayed "Error : bad status code 400, retrying in some seconds". In the browser console, it showed :

Failed to load resource : the server responded with a status of 400 (Bad Request)


Inside the MediaMTX container's runtime logs, this is what's displayed :

I'm not sure what this is supposed to mean ? Why isn't the server able to stream this 3-second, 709kb video even once ? The browser connected to the server and the URL successfully, but no data was being transferred.


Just in case, I decided to manually convert all of my mp4 files to webm using ffmpeg, and verified with Window's media player that the webm videos work. Then, I modified MediaMTX's configuration to stream the webm videos directly :


paths:
 # example:
 # my_camera:
 # source: rtsp://my_camera
 ~^demo\d+$:
 runOnDemand: ffmpeg -re -stream_loop -1 -i /vids/$MTX_PATH.webm -c copy -f webm http://localhost:8889/$MTX_PATH/whip


However, the error persists :

This is the same when I try to stream my other videos (demo1.mp4, demo2.mp4 etc.). What am I doing wrong ?
