Multilang : améliorer l’interface pour les blocs multilingues
18 février 2011, parMultilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela. -
Emballe médias : à quoi cela sert ?

no access to m3u8 when using ffmpeg [closed]
7 octobre 2023, par asdI have a code that allows me to download videos from
.m3u8, but for some reason it hasn't worked since yesterday

ffmpeg -user_agent "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/117.0.0.0 Safari/537.36" -headers "Referer: https://upstream.to/" -i "https://s92.upstreamcdn.co/hls2/01/03509/wc3i5yhdfgyk_o/master.m3u8?t=M9p8oTpo_LgYLnh2Ay4UEOT6Szltp5vGepiZ09ZjnFo&s=1696668614&e=10800&f=17548793&i=169.150&sp=0" -c copy -bsf:a aac_adtstoasc "name.mp4"


what can I do to make it similar to the upstream task which looks like this

NumPy array of a video changes from the original after writing into the same video
29 mars 2021, par RashiqI have a video (
test.mkv) that I have converted into a 4D NumPy array - (frame, height, width, color_channel). I have even managed to convert that array back into the same video (test_2.mkv) without altering anything. However, after reading this new,test_2.mkv, back into a new NumPy array, the array of the first video is different from the second video's array i.e. their hashes don't match and thenumpy.array_equal()function returns false. I have tried using both python-ffmpeg and scikit-video but cannot get the arrays to match.

Python-ffmpeg attempt :


import ffmpeg
import numpy as np
import hashlib

file_name = 'test.mkv'

# Get video dimensions and framerate
probe = ffmpeg.probe(file_name)
video_stream = next((stream for stream in probe['streams'] if stream['codec_type'] == 'video'), None)
width = int(video_stream['width'])
height = int(video_stream['height'])
frame_rate = video_stream['avg_frame_rate']

# Read video into buffer
out, error = (
 ffmpeg
 .input(file_name, threads=120)
 .output("pipe:", format='rawvideo', pix_fmt='rgb24')
 .run(capture_stdout=True)
)

# Convert video buffer to array
video = (
 np
 .frombuffer(out, np.uint8)
 .reshape([-1, height, width, 3])
)

# Convert array to buffer
video_buffer = (
 np.ndarray
 .flatten(video)
 .tobytes()
)

# Write buffer back into a video
process = (
 ffmpeg
 .input('pipe:', format='rawvideo', s='{}x{}'.format(width, height))
 .output("test_2.mkv", r=frame_rate)
 .overwrite_output()
 .run_async(pipe_stdin=True)
)
process.communicate(input=video_buffer)

# Read the newly written video
out_2, error = (
 ffmpeg
 .input("test_2.mkv", threads=40)
 .output("pipe:", format='rawvideo', pix_fmt='rgb24')
 .run(capture_stdout=True)
)

# Convert new video into array
video_2 = (
 np
 .frombuffer(out_2, np.uint8)
 .reshape([-1, height, width, 3])
)

# Video dimesions change
print(f'{video.shape} vs {video_2.shape}') # (844, 1080, 608, 3) vs (2025, 1080, 608, 3)
print(f'{np.array_equal(video, video_2)}') # False

# Hashes don't match
print(hashlib.sha256(bytes(video_2)).digest()) # b'\x88\x00\xc8\x0ed\x84!\x01\x9e\x08 \xd0U\x9a(\x02\x0b-\xeeA\xecU\xf7\xad0xa\x9e\\\xbck\xc3'
print(hashlib.sha256(bytes(video)).digest()) # b'\x9d\xc1\x07xh\x1b\x04I\xed\x906\xe57\xba\xf3\xf1k\x08\xfa\xf1\xfaM\x9a\xcf\xa9\t8\xf0\xc9\t\xa9\xb7'


Scikit-video attempt :


import skvideo.io as sk
import numpy as np

video_data = sk.vread('test.mkv')

sk.vwrite('test_2_ski.mkv', video_data)

video_data_2 = sk.vread('test_2_ski.mkv')

# Dimensions match but...
print(video_data.shape) # (844, 1080, 608, 3)
print(video_data_2.shape) # (844, 1080, 608, 3)

# ...array elements don't
print(np.array_equal(video_data, video_data_2)) # False

# Hashes don't match either
print(hashlib.sha256(bytes(video_2)).digest()) # b'\x8b?]\x8epD:\xd9B\x14\xc7\xba\xect\x15G\xfaRP\xde\xad&EC\x15\xc3\x07\n{a[\x80'
print(hashlib.sha256(bytes(video)).digest()) # b'\x9d\xc1\x07xh\x1b\x04I\xed\x906\xe57\xba\xf3\xf1k\x08\xfa\xf1\xfaM\x9a\xcf\xa9\t8\xf0\xc9\t\xa9\xb7'


I don't understand where I'm going wrong and both the respective documentations do not highlight how to do this particular task. Any help is appreciated. Thank you.

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 :
