How to import FFmpegMediaMetadataRetriever();?

[NeighborhoodCoding]

I added gradle and lib,
but

FFmpegMediaMetadataRetriever mmr = new FFmpegMediaMetadataRetriever();

has red lines..

Hello @NeighborhoodCoding

Make sure you are adding:

dependencies {
    implementation 'com.github.wseemann:FFmpegMediaMetadataRetriever-core:1.0.16'
    implementation 'com.github.wseemann:FFmpegMediaMetadataRetriever-native:1.0.16'
}

to your app or libraries build.gradle. Sync your project after that and the library should be available then.

Documentation about the library can be found here.

Thanks for your answer.
This works fine.
But

FFmpegMediaMetadataRetriever mmr_ffmpeg = new FFmpegMediaMetadataRetriever();

is not working...

It maybe my importation is some wrong? sorry.

Thanks in advance.

I'm currently build APK in windows OS. It is no problem I believe, it is OK? T.T

Thanks for your answer. I was using mmr by

MediaMetadataRetriever mmr = new MediaMetadataRetriever();
xmmr.setDataSource(this.getApplicationContext(), mVideoUri);

This works fine. mVideoUri is "androud.resource://org.appname/raw/video1" and I don't know about this.getApplicationContext() actually.

But

FFmpegMediaMetadataRetriever mmr_ffmpeg = new FFmpegMediaMetadataRetriever();
mmr_ffmpeg.setDataSource(this.getApplicationContext(), mVideoUri);

is not working...

As noted in the documentation, setDataSource will throw an exception if an error occurs when attempting to set the data source.
