This is a 5 MB cut from the first track on the Star Trek Original Series HD-DVDs... HD-DVDs were decrypted and ripped using SlySoft AnyDVD HD, and playback was attempted with mplayer SVN r25035 under Ubuntu Gutsy. This EVO *does* have E-AC3 and mlp tracks (and my mplayer is patched accordingly) but purposes of debugging, playback has been attempted with -ao null. Attempting to play this file in non-verbose mode starts with mplayer just sitting there and ends with it failing back out to the shell. No playback window is initialized. mplayer in Verbose mode returns the following (many identical lines cut to make the file not 18 MB): MPlayer dev-SVN-r25035-4.1.3 (C) 2000-2007 MPlayer Team CPU: Intel(R) Core(TM)2 Duo CPU E4500 @ 2.20GHz (Family: 6, Model: 15, Stepping: 13) CPUflags: MMX: 1 MMX2: 1 3DNow: 0 3DNow2: 0 SSE: 1 SSE2: 1 Compiled for x86 CPU with extensions: MMX MMX2 SSE SSE2 get_path('codecs.conf') -> '/root/.mplayer/codecs.conf' Reading /root/.mplayer/codecs.conf: 118 audio & 237 video codecs Configuration: --prefix=/usr CommandLine: '-v' 'Eps02.EVO' init_freetype get_path('font/font.desc') -> '/root/.mplayer/font/font.desc' font: can't open file: /root/.mplayer/font/font.desc font: can't open file: /usr/share/mplayer/font/font.desc Using MMX (with tiny bit MMX2) Optimized OnScreenDisplay get_path('fonts') -> '/root/.mplayer/fonts' Using nanosleep() timing get_path('input.conf') -> '/root/.mplayer/input.conf' Can't open input config file /root/.mplayer/input.conf: No such file or directory Can't open input config file /usr/etc/mplayer/input.conf: No such file or directory Falling back on default (hardcoded) input config Setting up LIRC support... get_path('Eps02.EVO.conf') -> '/root/.mplayer/Eps02.EVO.conf' Playing Eps02.EVO. get_path('sub/') -> '/root/.mplayer/sub/' [file] File size is 8380733440 bytes STREAM: [file] Eps02.EVO STREAM: Description: File STREAM: Author: Albeu STREAM: Comment: based on the code from ???
