FFmpegMediaMetadataRetriever is a reimplementation of Android's MediaMetadataRetriever class. The FFmpegMediaMetadataRetriever class provides a unified interface for retrieving frame and meta data from an input media file and uses FFmpeg as its backend.
Key Features:
- Support for API 7+ (Not just API level 10+ like MediaMetadataRetriever)
- URL support (Unlike MediaMetadataRetriever, see: http://code.google.com/p/android/issues/detail?id=35794)
Supported protocols:
- file, http, https, mms and mmsh
Supported formats (audio and video):
- aac, acc+, avi, flac, mp2, mp3, mp4, ogg, 3gp and more!
Additional support for:
- ICY Metadata (SHOUTcast metadata)
Extract and copy the following JAR file and prebuilt native libraries into your projects "libs" folder:
A sample application that makes use of FFmpegMediaMetadataRetriever can be downloaded at: https://github.com/wseemann/FFmpegMediaMetadataRetriever/blob/master/fmmr-demo/FMMRDemo.apk. Note: The sample application is compiled with support for ALL available formats. This results in a larger library and APK. FFmpeg can be recompiled with a subset of codecs enabled for those wanting a smaller size.
FFmpegMediaMetadataRetriever relies on FFmpeg and native code. The build process is complex and may be confusing for those unfamiliar the Android NDK. For this reason I've precompiled the modules created by the build process and checked them in at: https://github.com/wseemann/FFmpegMediaMetadataRetriever/blob/master/fmmr-library/prebuilt-libs.tar.gz. The modules are also included with the library. If you don't want to build the modules you can simple unzip the prebuilt ones and copy them to your projects "libs" folder. (Note: copy them to YOUR projects "libs" folder, NOT the "libs" folder located in FFmpegMediaMetadataRetriever/fmmr-library. Once this step is complete you can use the library (See: Installation in Eclipse (Kepler)). If you want to compile the modules yourself follow the Ant instructions listed below before attempting to use the library.
Download and install the Android SDK. Download the Android NDK. Clone/Download/Fork the repo through GitHub or via (read-only)
git clone https://github.com/wseemann/FFmpegMediaMetadataRetriever.git
Note: The build instructions and scripts assume you are running Unix or Linux. Building on other operating systems is currently not supported.
Execute the following in the FFmpegMediaMetadataRetriever/fmmr-library/ directory (assuming /path/to/android_sdk/tools is in your PATH):
android update project --path .
Open the newly created local.properties file and add the following lines:
ndk.dir=<path to NDK>
libs.dir=<path to target libs folder>
where is the path to your Android NDK, for example:
ndk.dir=/home/wseemann/Android/android-ndk-r8e
and is the path to the "libs" folder in the project that will use the library, for example:
libs.dir=/home/wseemann/Android/MyAndroidDemo/libs
To compile the library, navigate to FFmpegMediaMetadataRetriever/fmmr-library/ and execute
ant clean debug
The first step is to choose File > Import or right-click in the Project Explorer and choose Import. If you don't use E-Git to integrate Eclipse with Git, skip the rest of this paragraph. Choose "Projects from Git" as the import source. From the Git page, click Clone, and enter the URI of this repository. That's the only text box to fill in on that page. On the following pages, choose which branches to clone (probably all of them) and where to keep the local checkout, and then click Finish. Once the clone has finished, pick your new repository from the list, and on the following page select 'Use the New Projects wizard'.
From here the process is the same even if you don't use E-Git. Choose 'Android Project from Existing Code' and then browse to where you checked out FFmpegMediaMetadataRetriever. Select the fmmr-library folder and click Finish.
Finally, to add the library to your application project, right-click your project in the Package Explorer and select Properties. Pick the "Android" page, and click "Add..." from the bottom half. You should see a list including the FFmpegMediaMetadataRetriever project as well as any others in your workspace.
Sample code:
FFmpegMediaMetadataRetriever mmr = new FFmpegMediaMetadataRetriever();
mmr.setDataSource(mUri);
mmr.extractMetadata(FFmpegMediaMetadataRetriever.METADATA_KEY_ALBUM);
mmr.extractMetadata(FFmpegMediaMetadataRetriever.METADATA_KEY_ARTIST);
Bitmap b = mmr.getFrameAtTime(2000000, FFmpegMediaMetadataRetriever.OPTION_CLOSEST); // frame at 2 seconds
byte [] artwork = mmr.getEmbeddedPicture();
mmr.release();
