I had never given it any kind of attention until a Google search recently led me to the documentation. I always assumed that it just supported raw formats and some common, open MPEG formats. It turns out that the <a href=\"http:\/\/java.sun.com\/products\/java-media\/jmf\/2.1.1\/formats.html\">library actually supports<\/a> a few better known codecs, some of which are not completely reverse engineering. Of course, my interest in this would be decompiling them and de-obfuscating them beforehand, as necessary. The library contains a non-obfuscated, pure-Java implementation of the Cinepak codec. It also includes an obfuscated, pure-Java implementation of what I believe are some or all of the MPEG-1 codecs.<\/p>\n<p>However, most interesting codecs (including all of those that are not yet RE&#8217;d) are only supported via the Win32 or Linux\/Solaris &#8220;Performance Packs&#8221; which are presumably compiled, SIMD-optimized x86 code.<\/p>\n<p>Some curious features&#8211; the pure-Java portion of the library supports some of the quirkier Sound Blaster playback frequencies like 11127 Hz and 22254 Hz (while the performance packs support 8000 Hz -> 48000 Hz). Also, I can not get over the fact that the <a href=\"http:\/\/java.sun.com\/products\/java-media\/jmf\/2.1.1\/apidocs\/javax\/media\/format\/VideoFormat.html\">documentation for the javax.media.format.VideoFormat<\/a> class states that SMC corresponds to &#8220;Sorenson format&#8221;. (<a href=\"http:\/\/multimedia.cx\/smc.txt\">Here is the SMC format, apparently named for its creator, one Sean M. Callahan<\/a>.)<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Surveying the Java Multimedia Format
