undefined reference to ffmpeg functions in native code using Android Studio 2.2

12 octobre 2016, par Krzysztof Kansy

I have a problem with using ffmpeg in Android Studio 2.2 using NDK 13 and new Cmake building system. FFmpeg version is 3.1.4.
The system I’m working on is Linux Mint 18 64-bit.
At the build time I’m getting undefined reference error each time I use ffpeg functions.

My MainActivity.java :

public class MainActivity extends AppCompatActivity {



    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);



    // Example of a call to a native method

    TextView tv = (TextView) findViewById(R.id.sample_text);

    tv.setText(stringFromJNI());

    }



    /**

     * A native method that is implemented by the 'native-lib' native library,

     * which is packaged with this application.

     */

    public native String stringFromJNI();



    // Used to load the 'native-lib' library on application startup.

    static {

        System.loadLibrary("native-lib");

    }

}

My native class (undefined reference is pointing to av_init_packet(&avPacket)) :

#include 

#include <string>

#include <android></android>log.h>

#include <libavcodec></libavcodec>avcodec.h>





extern "C"

jstring

Java_com_example_tito_jnitest_MainActivity_stringFromJNI(

        JNIEnv* env,

        jobject /* this */) {



    std::string hello = "Hello from C++";



    __android_log_print(ANDROID_LOG_INFO, "JNItest", "Hello from JNI!");



    AVPacket avPacket;

    av_init_packet(&amp;avPacket);



    return env->NewStringUTF(hello.c_str());

}

</string>

Build process of ffmpeg seemed to be successful. Here’s my build script :

One thing I noticed that could indicate that something is wrong with ffmpeg build is warning WARNING: /home/tito/Android/Sdk/ndk-bundle/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/bin/arm-linux-androideabi-pkg-config not found, library detection may fail. during building. I’m not sure if this may be cause of problems.

I was trying to build for all of the ABIs, but for now I decided to focus on making just armeabi working. I’m having exact same failure after using e.g. arm64-v8a.

Finally, here is the gradle console’s content with error :

Can anyone tell me what I’m doing wrong here ?

Python to generate a video mpd file (even a node package) [on hold]

14 mars 2017, par Junior

I am in the midst of developing a video streaming app and I’m currently stuck at the Adaptive Bitrate Streaming part.

Is there a python or node module that can (run server-side and) generate a mpd file of a video after it is uploaded, this way it is easy to link the file to Dash.js.

So to clarify, I would just upload my video and have the server generate an mpd file for the video. The next time I use Dash.js, i just attach this file.

Thanks.

Fluent-ffmpeg "not a suitable output format"

5 septembre 2015, par J4G

I’m using the fluent-ffmpeg module for Node.js to convert audio files. I have a .mp3 file that I’d like to convert to .wma

Here’s what that looks like :

var proc = new ffmpeg({

   source: 'file.mp3',

   nolog: false

}).toFormat('wma')                                                

  .saveToFile('file.wma', function(stdout, stderr)

{                                                 

    console.log(stderr);

});

Unfortunately, I get the error :

Requested output format 'wma' is not a suitable output format

This is the entire error log :

I know this isn’t an ffmpeg issue because

ffmpeg -i file.mp3 file.wma

Works fine. Any ideas ?
