Android Studio FFMPEG "Protocol not found"
26 novembre 2022, par Whitestripe7773I am trying to run ffmpeg with android studio, but when I try the following code it shows this error message :


E/mobile-ffmpeg : content ://media/external/video/media/68 : Protocol not found
E/mobile-ffmpeg : Did you mean file:content ://media/external/video/media/68 ?


This is my code :


inputVideo = "content://media/external/video/media/68"
videoTitle = "abc"
public void method(String inputVideo, String videoTitle) {
 String cmdLine = "-i " + inputVideo + " -vcodec libx265 -crf 28 file:" + videoTitle;
 FFmpeg.execute(cmdLine);
 }


I think that the 'content :' in inputVideo leads to the error but I don't know how I could fix it.
Already tried out the following :


- 

- Add 'file :' in front of inputVideo and videoTitle
- Removing 'content ://' from the string leads to not finding the file

java.lang.NoClassDefFoundError Android Studio Unity
26 juin 2017, par NestorajI’m having some troubles when I try to generate a library that contains another one in Android Studio. First of all I am using Android Studio 2.0 and Unity 5.3.4f1. What I want to do is integrate FFMpeg in Unity so I decided to create my own library that use FFMpeg library as an intermediary. The FFMpeg library is here.
To start I created a new empty project in Android Studio and inside of it, created a new module, which will be my library, using New->Module->Android Library and named it "ffmpegcodec". After that I opened build.gradle file inside the new module folder and paste :
compile 'com.writingminds:FFmpegAndroid:0.3.2'inside dependencies brackets, and click Sync (It did not show any error).
After that create a new Java Class inside src/main/java/package-name/ and named it FFMpegCodec. Inside this paste this code :
public class FFMpegCodec {
private static FFmpeg ffmpeg;
private static Context context;
private static FFMpegCodec INSTANCE = null;
public FFMpegCodec(){
INSTANCE = this;
}
public static FFMpegCodec instance(){
if(INSTANCE == null){
INSTANCE = new FFMpegCodec();
}
return INSTANCE;
}
public void setContext(Context ctx){
this.context = ctx;
}
public void loadFFMpegBinary() {
try {
if (ffmpeg == null) {
ffmpeg = FFmpeg.getInstance(context);
}
ffmpeg.loadBinary(new LoadBinaryResponseHandler() {
@Override
public void onFailure() {
Log.e("FFMPEG", "ffmpeg : NOT correct Loaded");
}
@Override
public void onSuccess() {
Log.e("FFMPEG", "ffmpeg : correct Loaded");
}
});
} catch (FFmpegNotSupportedException e) {
} catch (Exception e) {
}
}
public void execFFmpegCommand(final String[] command) {
try {
ffmpeg.execute(command, new ExecuteBinaryResponseHandler() {
@Override
public void onFailure(String s) {
Log.e("FFMPEG", "FAILED with output : " + s);
}
@Override
public void onSuccess(String s) {
Log.e("FFMPEG", "SUCCESS with output : " + s);
}
@Override
public void onProgress(String s) {
Log.e("FFMPEG", "Started command : ffmpeg " + command);
Log.e("FFMPEG", "progress : " + s);
}
@Override
public void onStart() {
Log.e("FFMPEG", "Started command : ffmpeg " + command);
}
@Override
public void onFinish() {
Log.e("FFMPEG", "Finished command : ffmpeg " + command);
}
});
} catch (FFmpegCommandAlreadyRunningException e) {
// do nothing for now
}
}It basically generates an instance of FFmpeg and makes calls of ffmpeg commands.
Once I have my lib done I decided to test it in my project so I include my lib in my app graddle using :
compile project(':ffmpegcodec')After that I just paste this code to my MainActivity :
public class MainActivity extends AppCompatActivity {
FFMpegCodec ffmpeg;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button execCommandButton = (Button) findViewById(R.id.execCommandButton);
ffmpeg = FFMpegCodec.instance();
execCommandButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(getApplicationContext(), "This is a Toast!!", Toast.LENGTH_SHORT).show();
ffmpeg.setContext(MainActivity.this);
ffmpeg.loadFFMpegBinary();
String []cmd = new String[1];
cmd[0] = "-version";
ffmpeg.execFFmpegCommand(cmd);
}
});
}After that, I run my project and when I press the button it returns that everythings its ok, showing ffmpeg version.
Once I have check that my lib works I decide to move it to Unity so copy the ffmpegcodec-realese.arr file inside ffmpegcodec/build/outputs/aar folder and paste it into my Unity project. Then I wrote an C# script to use my lib that contains this :using System;
using System.Runtime.InteropServices;
using UnityEngine;
using System.Collections;
using System.Diagnostics;
public class ScreenRecorder {
private AndroidJavaObject unityActivity = null;
private AndroidJavaObject captureObject = null;
// Use this for initialization
public ScreenRecorder () {
try{
using (AndroidJavaClass unityPlayerActivityClass = new AndroidJavaClass("com.unity3d.player.UnityPlayer")) {
unityActivity = unityPlayerActivityClass.GetStatic<androidjavaobject>("currentActivity");
}
AndroidJavaClass captureClass = new AndroidJavaClass ("com.promineostudios.ffmpegcodec.FFMpegCodec");
if (captureClass != null) {
captureObject = captureClass.CallStatic<androidjavaobject>("instance");
captureObject.Call("setContext", unityActivity);
captureObject.Call("loadFFMpegBinary");
}
}catch(Exception ex){
UnityEngine.Debug.Log(ex);
}
}
}
</androidjavaobject></androidjavaobject>The problems comes here. When I create a class instance using :
AndroidJavaClass captureClass = new AndroidJavaClass ("com.promineostudios.ffmpegcodec.FFMpegCodec");It creates an instance correctly, and also when I create an object using :
captureObject = captureClass.CallStatic<androidjavaobject>("instance");
</androidjavaobject>But when I try to get access to FFMpeg library methods like in "setContext" it fails and returns this :
UnityEngine.AndroidJavaException: java.lang.NoClassDefFoundError: Failed resolution of: Lcom/github/hiteshsondhi88/libffmpeg/FFmpeg;
