Unrelated to the subject, but in this case (ffprobe/ffmpeg) you can just ignore this error. Java will be used only when you play the disc with disc menus. > This error message does not appear when installing OpenJDK 7. > > I took a look at the source code of Libbluray and saw that the path > to > the JVM for OpenJDK 8 is missing: > > http://git.videolan.org/?p=libbluray.git;a=blob;f=src/libbluray/bdj/b > dj.c;h=101d33564083a900f8bed5ba0b47536e5402841f;hb=HEAD#l203 Yes, only few most common paths are listed. Easiest way to fix this at runtime is to use JAVA_HOME environment variable: JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64/ ffmpeg ...

Adding all possible Java versions from every distribution to libbluray would be huge task. Also, it would require continuous maintenance and updating the paths every time new Java version is released. It should be possible to specify distribution-specific location for JVM at build time (JDK_HOME=... ./configure ...), if distribution has ex. permanent symlink to current/default JVM. > Best Regards. > _______________________________________________ > libbluray-devel mailing list > libbluray-devel@videolan.org > https://mailman.videolan.org/listinfo/libbluray-devel _______________________________________________ libbluray-devel mailing list libbluray-devel@videolan.org https://mailman.videolan.org/listinfo/libbluray-devel
