JAVE (Java Audio Video Encoder) 类库是一个 ffmpeg 项目的 Java 语言封装。开发人员可以使用JAVE 在不同的格式间转换视频和音频。例如将 AVI 转成 MPEG 动画，等等 ffmpeg 中可以完成的在 JAVE 都有对应的方法。

Examples

From a generic AVI to a youtube-like FLV movie, with an embedded MP3 audio stream:

File source = new File("source.avi");
File target = new File("target.flv");
AudioAttributes audio = new AudioAttributes();
audio.setCodec("libmp3lame");
audio.setBitRate(new Integer(64000));
audio.setChannels(new Integer(1));
audio.setSamplingRate(new Integer(22050));
VideoAttributes video = new VideoAttributes();
video.setCodec("flv");
video.setBitRate(new Integer(160000));
video.setFrameRate(new Integer(15));
video.setSize(new VideoSize(400, 300));
EncodingAttributes attrs = new EncodingAttributes();
attrs.setFormat("flv");
attrs.setAudioAttributes(audio);
attrs.setVideoAttributes(video);
Encoder encoder = new Encoder();
encoder.encode(source, target, attrs);

Next lines extracts audio informations from an AVI and store them in a plain WAV file:

File source = new File("source.avi");
File target = new File("target.wav");
AudioAttributes audio = new AudioAttributes();
audio.setCodec("pcm_s16le");
EncodingAttributes attrs = new EncodingAttributes();
attrs.setFormat("wav");
attrs.setAudioAttributes(audio);
Encoder encoder = new Encoder();
encoder.encode(source, target, attrs);

Next example takes an audio WAV file and generates a 128 kbit/s, stereo, 44100 Hz MP3 file:

File source = new File("source.wav");
File target = new File("target.mp3");
AudioAttributes audio = new AudioAttributes();
audio.setCodec("libmp3lame");
audio.setBitRate(new Integer(128000));
audio.setChannels(new Integer(2));
audio.setSamplingRate(new Integer(44100));
EncodingAttributes attrs = new EncodingAttributes();
attrs.setFormat("mp3");
attrs.setAudioAttributes(audio);
Encoder encoder = new Encoder();
encoder.encode(source, target, attrs);

Next one decodes a generic AVI file and creates another one with the same video stream of the source and a re-encoded low quality MP3 audio stream:

File source = new File("source.avi");
File target = new File("target.avi");
AudioAttributes audio = new AudioAttributes();
audio.setCodec("libmp3lame");
audio.setBitRate(new Integer(56000));
audio.setChannels(new Integer(1));
audio.setSamplingRate(new Integer(22050));
VideoAttributes video = new VideoAttributes();
video.setCodec(VideoAttributes.DIRECT_STREAM_COPY);
EncodingAttributes attrs = new EncodingAttributes();
attrs.setFormat("avi");
attrs.setAudioAttributes(audio);
attrs.setVideoAttributes(video);
Encoder encoder = new Encoder();
encoder.encode(source, target, attrs);

Next one generates an AVI with MPEG 4/DivX video and OGG Vorbis audio:

File source = new File("source.avi");
File target = new File("target.avi");
AudioAttributes audio = new AudioAttributes();
audio.setCodec("libvorbis");
VideoAttributes video = new VideoAttributes();
video.setCodec("mpeg4");
video.setTag("DIVX");
video.setBitRate(new Integer(160000));
video.setFrameRate(new Integer(30));
EncodingAttributes attrs = new EncodingAttributes();
attrs.setFormat("mpegvideo");
attrs.setAudioAttributes(audio);
attrs.setVideoAttributes(video);
Encoder encoder = new Encoder();
encoder.encode(source, target, attrs);

A smartphone suitable video:

File source = new File("source.avi");
File target = new File("target.3gp");
AudioAttributes audio = new AudioAttributes();
audio.setCodec("libfaac");
audio.setBitRate(new Integer(128000));
audio.setSamplingRate(new Integer(44100));
audio.setChannels(new Integer(2));
VideoAttributes video = new VideoAttributes();
video.setCodec("mpeg4");
video.setBitRate(new Integer(160000));
video.setFrameRate(new Integer(15));
video.setSize(new VideoSize(176, 144));
EncodingAttributes attrs = new EncodingAttributes();
attrs.setFormat("3gp");
attrs.setAudioAttributes(audio);
attrs.setVideoAttributes(video);
Encoder encoder = new Encoder();
encoder.encode(source, target, attrs);

Dear Community,

I’m pleased to announce that the Spring ActionScript 0.8 release is now available.

Download | API Documentation | HTML Docs | PDF Docs | Changelog

This release includes the Spring ActionScript framework, the Cairngorm extensions and the PureMVC extensions.

All libraries are available for download at the following Maven repository: http://projects.yoolab.org/maven/content/repositories/

From now on, we will regularly publish new snapshots of the libraries there.

Direct links to the libraries:
- Spring ActionScript 0.8
- Spring ActionScript Cairngorm 0.8
- Spring ActionScript PureMVC 0.8

Dependencies:
- AS3Commons Lang
- AS3Commons Logging
- AS3Commons Reflect

Note: AS3Commons Lang is a snapshot of 1.0. We will work with a release for the following releases of Spring ActionScript

Besides a series of bugfixes, optimizations and improvements, some of the major changes and enhancements include:

Autowiring support

Using autowiring allows you to inject objects managed by the container into view components and other objects. To autowire a property, annotate it with the [Autowired] metadata tag. The support we build in is pretty enhanced and allows you to customize the autowire behavior in many different ways. Within the Autowired metadata tag you can specify the object name and you can also configure the container to filter autowire candidates using your own filter specifications. Please see the documentation on autowiring for more info.

Custom Namespaces

The XML configuration now supports namespaces and allows you to create custom namespaces yourself. A few namespaces have been added to simplify the configuration of common objects for RMI and Messaging. More info on available namespaces and schemas and creating custom ones can be found in the documentation. The XSD schemas are available http://www.springactionscript.org/schema/

MXML Configuration

We now also support configuration through MXML. The markup is very similar to the regular XML config, but with some slight differences. Please see the documentation on MXML Configuration

AS3Commons

As a side project, we have started the AS3Commons project that offers reusable ActionScript 3.0 libraries. Most of the libraries currently available in AS3Commons are build using code from the Spring ActionScript framework. This means that a lot of code has been removed from Spring ActionScript and is now available for use in projects not using Spring ActionScript. Please note that you might have to update quite some import statements to refer to AS3Commons instead of Spring ActionScript. We apologize for any inconvenience this might cause, but this is only a one-time process.

We hope you find the AS3Commons libraries useful. All libraries (releases and snapshots) can also be found at the Maven repository.

Documentation

The documentation has been tremendously improved in this version. Next to the API documentation, we now provide a reference guide in HTML and PDF format. General info can be found at the project website: www.springactionscript.org

Last Words

If you feel like helping us out, we could certainly use your help. This project is entirely created on a volunteer basis and in our spare (and limited) free time so needless to say that the more people, the faster we can deliver new releases and guarantee the quality of the framework. So if you think you have someting to offer, be it as a developer, tester, documentation writer, sample creator, … please contact me (christophe [DOT] herreman [AT] gmail [DOT] com) or leave something in the comments. All help is more than welcome.

Enjoy this release and have fun coding!

Red5 is an open source Flash server written in Java. It does not include a standalone client yet but I was able to write a Java program that uses Red5 to connect to an RTMP video stream and record / save it to a file. Code is provided below and also some tips on how to get the details required to download flash videos that you come across on the internet.

Here’s the code of “MyRtmpClient.java”, you are free to use and modify this in any way you want.

To compile and run the code you need the following libraries:

commons-collections-3.2.jar
jcl104-over-slf4j-1.4.3.jar
logback-classic-0.9.8.jar
logback-core-0.9.8.jar
mina-core-1.1.6.jar
red5.jar
slf4j-api-1.4.3.jar
spring-beans-2.0.8.jar
spring-context-2.0.8.jar
spring-core-2.0.8.jar

We need the latest Red5 JAR built from version control (not the latest official release) and I have uploaded these files here: red5-rtmp-client-libszip.pdf – just rename the file to end with “.zip” after downloading.

The code shown is hard-coded to connect to “localhost”, app name “oflaDemo” and stream name “IronMan.flv” which can be tested on the official Red5 server distribution which you can download and run. When it comes to downloading flash streams from the internet, WireShark can be used to sniff out the values you need.

Let’s take this site for example: http://videolectures.net/ Start a WireShark capture session before clicking on a video on the site to play it. Let WireShark grab all the information exchanged between your PC and the remote flash server and you can stop the capture once the video begins to play, we are only interested in what goes on during the connection handshake. I will use this video as an example: http://videolectures.net/ff06_chomsky_szmp/ [update Jun-2008: looks like they changed this particular video to Windows media instead of Flash, so try other videos or other sites]

In WireShark you can filter for protocol “rtmpt” and the first few entries would be handshake or “invoke” operations. Examining the “Handshake part 3″ we can easily get the value of the required “app” property. Below we can see it is “video/2006/other/ff06/chomsky_noam”:

For the host name, the IP address should do fine for most sites, but we can easily figure out the host name of the stream server from what appears after “rtmp://”. Note that WireShark allows you to search the text contents of captured packets. Here below we can see that the host name is “velblod.videolectures.net”:

And finally when the “play” command is issued – we need the value of the stream name. Below we see it is “chomsky_noam_01″:

So with the right values of hostname, app and stream name set – you can run the program and download the stream to your local drive for offline viewing. To download the whole stream – just change the duration to ‘-2′ as hinted in the source code comment. There are many free Flash players available you can use to play downloaded content such as FLV Player.

Do let me know if this works for you and if you find any additional parameters that need to be passed for other sites.
