maven在java开发中使用的频率很高，所以使用maven来搭建环境，直接使用javacv的maven依赖会把所有平台的jar包都现在下来很多也很慢，所以折腾了一下只下载windwos平台下的jar包。在windows打开摄像头成功，其中pom的依赖如下：
<properties> <javacpp.platform.dependencies>windows-x86_64</javacpp.platform.dependencies> </properties> <dependencies> <!-- https://mvnrepository.com/artifact/org.bytedeco/javacv --> <dependency> <groupId>org.bytedeco</groupId> <artifactId>javacv</artifactId> <version>1.4.1</version> <exclusions> <exclusion> <groupId>org.bytedeco.javacpp-presets</groupId> <artifactId>*</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>org.bytedeco.javacpp-presets</groupId> <artifactId>opencv</artifactId> <version>3.4.1-1.4.1</version> </dependency> <dependency> <groupId>org.bytedeco.javacpp-presets</groupId> <artifactId>opencv</artifactId> <version>3.4.1-1.4.1</version> <classifier>${javacpp.platform.dependencies}</classifier> </dependency> <!-- https://mvnrepository.com/artifact/org.bytedeco.javacpp-presets/ffmpeg --> <dependency> <groupId>org.bytedeco.javacpp-presets</groupId> <artifactId>ffmpeg</artifactId> <version>3.4.2-1.4.1</version> </dependency> <dependency> <groupId>org.bytedeco.javacpp-presets</groupId> <artifactId>ffmpeg</artifactId> <version>3.4.2-1.4.1</version> <classifier>${javacpp.platform.dependencies}</classifier> </dependency> </dependencies>其他的平台只需要更改javacpp.platform.dependencies为对应平台就行了，可以参考如下:
