The JAVE2 (Java Audio Video Encoder) library is Java wrapper on the ffmpeg project. Developers can take take advantage of JAVE2 to transcode audio and video files from a format to another. In example you can transcode an AVI file to a MPEG one, you can change a DivX video stream into a (youtube like) Flash FLV one, you can convert a WAV audio file to a MP3 or a Ogg Vorbis one, you can separate and transcode audio and video tracks, you can resize videos, changing their sizes and proportions and so on.
Many other formats, containers and operations are supported by JAVE2.
JAVE requires Java 8
JAVE can also be easily ported to other OS and hardware configurations, see the JAVE manual for details.

Maven Repository URL -> https://mvnrepository.com/artifact/ws.schild/jave-all-deps
It includes all binaries for the supported platforms
<dependency>
<groupId>ws.schild</groupId>
<artifactId>jave-all-deps</artifactId>
<version>2.4.5</version>
</dependency>You can use maven dependencies to include the libraries in your projects. Include the following in your pom files.
[ Remember always to check the latest release here ]
======= Generally if you want to use for one platform or more what you have to do is add the jave-core:
<dependency>
<groupId>ws.schild</groupId>
<artifactId>jave-core</artifactId>
<version>2.4.5</version>
</dependency>and then the specific jar(s) for your platform(s) :
<dependency>
<groupId>ws.schild</groupId>
<artifactId>jave-native-linux64</artifactId>
<version>2.4.5</version>
</dependency><dependency>
<groupId>ws.schild</groupId>
<artifactId>jave-native-win64</artifactId>

<groupId>ws.schild</groupId>

compile group: 'ws.schild', name: 'jave-native-linux64', version: '2.4.5'Jave2 consists of two main components:
- The
jave-coredependency, which includes all the java code, which is platform independent - The
jave-native-<platform>dependencies, which include the binary executables per platform
There exists a jave-all-deps project, which includes core and all windows und linux binaries.

- 2.4.6
- Prepare for next dev cycle
- Corrected win32 executable name, thanks to WavyPeng
- The bitrate was returned in kBps instead of Bps
- The channel detection did only work for mono+stereo, but not for quad (It does still not work for others)
- Added javadoc about volume and quality values
- 2.4.5
- Added video and audio quality flags for conversion (see VideoAttributes.quality and AudioAttributes.quality)
- Changed aac de/encoder from libvo_aacenc to default aac settings from ffmpeg
- Upgraded windows and osx binaries to 4.1 from https://ffmpeg.zeranoe.com/builds/
- Upgraded linux binaries to 4.1 from https://johnvansickle.com/ffmpeg/
- 2.4.4
- More informative error message when not finding ffmpeg executable
- Added option to copy over meta data if possible (setMapMetaData(true) in EncodingAttributes)
- Better handling of process exit code
- 2.4.3
- Upgraded windows and osx binaries to 4.0.2 from https://ffmpeg.zeranoe.com/builds/
- Upgraded linux binaries to 4.0.2 from https://johnvansickle.com/ffmpeg/
- Made output handling more robust,
- we now only throw an encoder exception when encoder exit code is not 0
- Unknown conversion lines can betrieved via encoder.getUnhandledMessages()
- Added abortEncoding method to be able to stop the running encoder
- 2.4.2
- Enhanced output parsing when using copy operator for streams
- Refactoring of outpout analyzer in own class for simpler unit tests
- 2.4.1
