哪个Java库可用于从连接的摄像机录制视频？ [英] Which Java library to use for record a video from a connected camera?
问题描述
您可能以为tere是一个简单的解决方案，但是没有：（
You would have thought that tere is a simple solution to this but there isn't :(
我的应用程序需要从USB /火线捕获流（或任何连接）连接的摄像机（结果将是 output.flv 之类的文件。）我希望我可以检测所有连接的摄像机并选择要使用的摄像机（一个或多个）时间->一个或多个输出文件）。应用程序必须是跨平台的。
My application needs to capture a stream from a USB/firewire (or whatever is the connection) connected camera (result would be a file like output.flv). I would prefer that I can detect all connected cameras and choose which one to use (one or more at the same time --> one or more output files). Application has to be cross platform.
找到的库：
- Xuggle -不是很好的相机支持。非常适合处理图像和视频。
- JMF -一个旧的API，但如果可以使用，我会的。我不会在下载页面上看到MAC OS X链接。
- FMJ -看起来像是JMF的更好版本，但找不到解决方法
- LTI-CIVIL -FMJ使用它。看起来它仅从相机捕获图像（而不是视频）。我可以使用Xuggle从LTI-CIVIL拍摄的图像创建视频。和FMJ一样，安装也很困难。
- Xuggle - not very good camera support. Good for manipulating over images and video.
- JMF - an old API but if I can use it, I will. I don't see a MAC OS X link on downloads page.
- FMJ - looks like a better version of JMF but a can't find a way of installing it.
- LTI-CIVIL - FMJ uses it. It looks like it only captures images from camera (not video). I could use Xuggle to create a video from images taken from LTI-CIVIL. And like FMJ, it is difficult to install.
您对此有何建议？
推荐答案
为此，我建议使用VLCj-它应该能够从网络摄像头流式传输到Java画布上而没有任何困难。它使用本机代码，因此您需要提供libvlc.so / dll，但是从那里可以在所有主要平台（Windows，Mac，Linux）上运行。
I'd recommend VLCj for this - it should be able to stream from webcams onto a Java canvas without any difficulties. It uses native code so you need to provide libvlc.so / dll but from there on it should work on all the major platforms (Windows, Mac, Linux).
您可能需要查看进程外播放器以获得完全可靠性，这要复杂一些（请参阅此处（到目前为止，我已经为此付出了很多努力）），但是一旦安装妥当，它应该可以正常工作。
You may need to look at out of process players for complete reliability which is a bit more complex (see here for my efforts so far) but once you've got that in place it should work fine.
