Question

我想在Linux计算机上运行简单的.flv到.mp4转换

直到现在我还包括以下依赖项，它在Ubuntu 12.x和CentOS上工作正常

<dependency>
   <groupId>org.bytedeco.javacpp-presets</groupId>
   <artifactId>ffmpeg</artifactId>
   <version>2.7.1-1.0</version>
   <classifier>linux-x86_64</classifier>
</dependency>

Red Hat uname -a

x86_64 #1 SMP Tue Sep 16 01:56:35 EDT 2014 x86_64 x86_64 x86_64 GNU/Linux

Red Hat lsb_release -a
LSB Version:    :base-4.0-amd64:base-4.0-noarch:core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch
Distributor ID: RedHatEnterpriseServer
Description:    Red Hat Enterprise Linux Server release 6.6 (Santiago)

CentOS uname -a

.x86_64 #1 SMP Tue Nov 3 19:10:07 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

但是在RedHat Linux中尝试时，我会遇到以下异常

应用程序启动失败

    at org.springframework.boot.loader.MainMethodRunner.run(MainMethodRunner.java:53)
    at java.lang.Thread.run(Thread.java:745)

我尝试使用32位版本：

<dependency>
   <groupId>org.bytedeco.javacpp-presets</groupId>
   <artifactId>ffmpeg</artifactId>
   <version>2.7.1-1.0</version>
   <classifier>linux-x86</classifier>
</dependency>

同样的结果。

然后我尝试了简单

org.bytedeco javacv 1.0

和mvn package -Dplatform.dependencies=true所以我得到了所有依赖项。

还是一样。任何人都知道我做错了什么？

Answer 1

avutil类在您使用的版本中不可用使用2.8.1-1.1版本。 <version>2.8.1-1.1</version>。
