From peter at cordes.ca Wed Nov 28 08:46:11 2007 From: peter at cordes.ca (Peter Cordes) Date: Wed, 28 Nov 2007 03:46:11 -0400 Subject: [libdca-devel] fails to decode 4.0 channel DTS48/24 Message-ID: <20071128074611.GB12038@cordes.ca> The DTS soundtrack from the BluRay of Edward Scissorhands is not decoded properly by mplayer, or by dcadec built from the svn r82 or libdca (on AMD64 Ubuntu Gutsy). It sounds chopped at 1kHz or something. A good description in words isn't coming to mind very easily, so just listen to the sample. I put a ~1 minute sample (14MB) on my web server: http://www.cordes.ca/~peter/bugs/libdca/scissorhands-4.0-48_24.dts or with 720p x264 video: 58MB http://www.cordes.ca/~peter/bugs/libdca/Edward.Scissorhands.x264.DTS-4.0-48_24.mkv I didn't know where to upload it, but I'd rather not host it indefinitely. Someone tell me where to put it, or copy it yourself and post on the list. The DTS stream is 1.5Mbit/s, 48kHz/24bit. My Logitech Z-5500 speakers decode it fine if I send to them over s/pdif. I enabled the verbose mode (by holding down the right set of buttons...), so the display readout says DTS 3/1 48 24 when it first sees the stream, which means 3 front, 1 rear, 48kHz, 24bit. I can't believe I was ever happy with the cheap speakers I had before these. OTOH, I wasn't really, which is why I bought these. :) This review of the disc says something about the soundtrack. http://bluray.highdefdigest.com/606/edwardscissorhands.html The DTS track I have is just the DTS core of the DTS-HD lossless track. mplayer decodes the soundtrack ok when it's downmixed to 2 channels. thanks, and happy hacking, -- #define X(x,y) x##y Peter Cordes ; e-mail: X(peter at cor , des.ca) "The gods confound the man who first found out how to distinguish the hours!

Hopefully the bug will be fixed sometime in the future. (If the bug also affect ffmpeg.) MvH Benjamin Larsson
