本文主要是介绍【OpenCV】【JavaCV】【Xuggler】【Java】获取视频的编解码器，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

        FFmpegFrameGrabber grabber = new FFmpegFrameGrabber(inputStream);grabber.start();System.out.println(JSON.toJSONString(grabber));System.out.println(grabber.getVideoMetadata().get("encoder"));

AVC Coding  即为 H.264
