Ogle is a dvd player with support for menus and subtitles. Currently, it lacks some audio formats support (PCM and ???), so a few DVDs will work with sound. As shipped, ogle cannot descramble DVDs. There are a few DVDs out there with no scramble protection. However, ogle will recognize and use an installed descrambling library. To run ogle, you need a graphics card well supported by XFree, including the Xvideo extension in YUV mode, and a sound card with 48KHz output (ATI card owners may wish to use the ATI-4.1.0.i386.tgz package) You can check your display Xvideo capabilities with xdpyinfo (presence of the Xvideo extension) and xvinfo (presence of an adapter with correct YUV capabilities). A positive test will usually look like: xvinfo Number of image formats: 4 ... id: 0x32315659 (YV12) guid: 59563132-0000-0010-8000-00aa00389b71 ... which is the encoding that ogle is looking for. Alternately, at the expense of more cpu power, ogle can also use SystemV shared memory, but the shared memory requirements exceed GENERIC parameters. You will need to crank them up. Configure a kernel with option SHMMAXPGS=4096 and edit param.c to set SHMSEG to 16, then recompile. The graphical interface add-on ogle-gui currently does not work on OpenBSD, but the program can be fully controlled from the keyboard anyways, see oglerc(5). Overall, ogle needs about 50% cpu for full-framerate decoding on a PIII700 with an ATI Mach64 Mobility and an ESS Maestro 2. If Xvideo YV12 is not available, ogle roughly needs 120% cpu on the same machine in 24 bits mode, and full screen rescale is not available. On i386, it's highly recommended to go to a 16 bits mode, where MMX acceleration code exists (requirements go down to 70% cpu). If you can, you may also wish to add several `non-standard' modes to your XF86Config. The most useful being 720x576. WWW: ${HOMEPAGE}
