Les vidéos
21 avril 2011, parComme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...) -

Camera app fails on android ffmpeg application
22 mars 2021, par connor449I am trying to run a simple video recorder app on android. The code is below :


package com.example.camera

//import android.R
import android.content.DialogInterface
import android.content.pm.PackageManager
import android.os.Build
import android.os.Bundle
import android.widget.Toast
import androidx.appcompat.app.AlertDialog
import androidx.appcompat.app.AppCompatActivity
import androidx.core.app.ActivityCompat
import androidx.core.content.ContextCompat
import com.arthenica.mobileffmpeg.FFmpeg


const val EXTRA_MESSAGE = "com.example.myfirstapp.MESSAGE"

class MainActivity : AppCompatActivity() {
 override fun onCreate(savedInstanceState: Bundle?) {
 super.onCreate(savedInstanceState)
 setContentView(R.layout.activity_main)
 if (checkPermission()) {
 //main logic or main code
 FFmpeg.execute("-f android_camera -i 0:0 -r 30 -pixel_format bgr0 -t 00:00:05 /sdcard/test.mp4")

 // . write your main code to execute, It will execute if the permission is already given.
 } else {
 requestPermission()
 }
 }

 private fun checkPermission(): Boolean {
 return if (ContextCompat.checkSelfPermission(this, android.Manifest.permission.CAMERA)
 != PackageManager.PERMISSION_GRANTED
 ) {
 // Permission is not granted
 false
 } else true
 }

 private fun requestPermission() {
 ActivityCompat.requestPermissions(
 this, arrayOf(android.Manifest.permission.CAMERA),
 PERMISSION_REQUEST_CODE
 )
 }

 override fun onRequestPermissionsResult(
 requestCode: Int,
 permissions: Array<string>,
 grantResults: IntArray
 ) {
 when (requestCode) {
 PERMISSION_REQUEST_CODE -> if (grantResults.size > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED
 ) {
 Toast.makeText(applicationContext, "Permission Granted", Toast.LENGTH_SHORT)
 .show()

 // main logic
 } else {
 Toast.makeText(applicationContext, "Permission Denied", Toast.LENGTH_SHORT)
 .show()
 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
 if (ContextCompat.checkSelfPermission(this, android.Manifest.permission.CAMERA)
 != PackageManager.PERMISSION_GRANTED
 ) {
 showMessageOKCancel("You need to allow access permissions",
 DialogInterface.OnClickListener { dialog, which ->
 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
 requestPermission()
 }
 })
 }
 }
 }
 }
 }

 private fun showMessageOKCancel(
 message: String,
 okListener: DialogInterface.OnClickListener
 ) {
 AlertDialog.Builder(this@MainActivity)
 .setMessage(message)
 .setPositiveButton("OK", okListener)
 .setNegativeButton("Cancel", null)
 .create()
 .show()
 }

 companion object {
 private const val PERMISSION_REQUEST_CODE = 200
 }
}


</string>

The main command to call the video recorder is here :


FFmpeg.execute("-f android_camera -i 0:0 -r 30 -pixel_format bgr0 -t 00:00:05 /sdcard/test.mp4")


The app opens on my android 10 Motorola G Power. I tap 'allow' for allowing permissions. Then the app crashes and I keep getting this error :

FFmpeg dosn't listen on RTP port in debian
26 juin 2021, par MSSI compose a command to encode my HLS audio stream to a mp3 stream :


ffmpeg -re -i "http://cdn1.live.irib.ir:1935/channel-live/smil:r-payam/chunklist_b307200_slFa.m3u8" -acodec libmp3lame -f rtp rtp://127.0.0.1:9434/


When I run the command on windows 10 machine FFmpeg start to listen on port 9434 and works perfectly :




But when I run it on my Debian machine it doesn't bind to specified port and also any of bind ports doesn't work :

Trying to add Watermark to Video FFMPEG
8 mai 2021, par Michael BouixI'm trying to add watermark to my video
When I upload some videos work fine, but some videos I get an error that retrieve the file with 0kb.
I don't know if its why the video is 4k... I have no idea
And I'm running another command to scale the video with the same file and work fine too, only when adding my watermark I get the error


This is the command :


$comando_arquivo_water = "/usr/bin/ffmpeg -nostdin -i ".$path_video." -i ".$path_logo." -filter_complex '[1][0]scale2ref=w=oh*mdar:h=ih*0.2[logo][video];[video][logo]overlay=(W-w)/2:(H-h)/2' -y ".$water_final_nome." > out.txt 2> err.txt";


And this is what I'm getting
