Does anyone know of a java library or jar file available to convert webm video files, that are currently used on youtube, to another format say mov or flv for example? Basically a decoder for the webm video format? I'm currently using the Java Audio and Video encoder (JAVE) tool for converting video files, which is excellent, but its last stable release was 2009 and therefore does not support the the new vp8 video stream. Looked around web but couldn't find any and looked at the file format looks fairly complex and difficult tool to build. Cheers.
