5 avril 2021, par Parv JainI want to convert a mp4 video file to mp3/wav audio using python ffmpeg or moviepy.
when I run this command


ffmpeg -i vid.mp4 -ar 44100 -vn audio.wav


It returns


Output file #0 does not contain any stream


Here is the full Log

I searched the internet for this but could not find a solution


Please tell if there is a way to do this with ffmpeg or another way


I also tried to use moviepy but it was not successful.


Here is moviepy log


Traceback (most recent call last):
 File "path\to\file\script.py", line 3, in <module>
 clip.audio.write_audiofile(r'audio.mp3')
AttributeError: 'NoneType' object has no attribute 'write_audiofile'
</module>

this is my code for moviepy


import moviepy.editor as mp
clip = mp.VideoFileClip('vid.mp4')
clip.audio.write_audiofile(r'audio.mp3')

youtube-dl (ffmpeg) blank error on embedding subtitles
22 mars 2021, par Human1I am new to using youtube-dl, and therefore is quite unfamiliar with how it works. I configured it to download auto subs and english subs (if there were any), and embed them in the video. It worked for me for quite a good while (1 or 2 months), and it suddenly stopped working with blank errors starting to pop up, and I have no idea why that happened. I have checked that I am using the most updated version of youtube-dl and ffmpeg. I am currently using a m1 mac , and I don't know if that caused the problem. Below is the output I got with the
-vcommand, as well as some background information.

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 :
