Error when using FFMpeg in a 64-bit .NET Framework 4.8 application with FFmpeg.AutoGen 7.0
17 janvier, par aueticI'm facing an issue when trying to use FFmpeg in my .NET Framework 4.8 application (64-bit) with FFmpeg.AutoGen 7.0. When I try to call any FFmpeg method, such as ffmpeg.av_version_info() in the constructor, I encounter the next "Not supported method" error :




System.NotSupportedException HResult=0x80131515 Mensaje = El método especificado no es compatible. Origen = FFmpeg.AutoGen.Bindings.DynamicallyLoaded Seguimiento de la pila : at FFmpeg.AutoGen.Bindings.DynamicallyLoaded.DynamicallyLoadedBindings.<>c.b__6_1165() at FFmpeg.AutoGen.Bindings.DynamicallyLoaded.DynamicallyLoadedBindings.<>c.b__6_454() at FFmpeg.AutoGen.Abstractions.ffmpeg.av_version_info()




My binaries path contains :




- 

- FFmpeg/bin :




- 

- avcodec-61.dll
- avdevice-61.dll
- avfilter-10.dll
- avformat-61.dll
- avutil-59.dll
- postproc-58.dll
- swresample-5.dll
- swscale-8.dll


















- 

- FFmpeg/include




- 

- libavcodec
- libavdevice
- libavfilter
- libavformat
- libavutil
- libpostproc
- libswrseample
- libswscale




















I'm using the FFmpeg binaries obtained from GitHub (https://github.com/Ruslan-B/FFmpeg.AutoGen) and I'm specifically working with FFmpeg version 7.0. This is the code snippet :


public sealed unsafe partial class VideoPlayer : Form
{
 private bool _isPlaying = false;
 private Thread playbackThread;
 private int _videoStreamIndex;
 private AVFormatContext* _formatContext;
 private AVCodecContext* _codecContext; 
 private SwsContext* _swsContext;

 public VideoPlayer()
 {
 InitializeComponent(); 
 FFMpegBinariesHelper.RegisterFFMpegBinaries(); // FFmpeg registration
 DynamicallyLoadedBindings.Initialize(); 
 Console.WriteLine($"FFmpeg version info: {ffmpeg.av_version_info()}"); // Error occurs here
 }
}

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 :
