DTS decoding (of DVD/AVI with DTS & *.dts)

DTS software decoding (of DVD/AVI with DTS & .dts) (this is not same FR as DTS pass-through/bypass) DTS decoding for DVD & AVI movies with DTS audio stream/'s and .dts files and .wav files encoded in DTS is wanted so we without a external DTS decoders can listen to those streams & tracks. I guess what is needed is to decode or transcode it and output the sound as RAW PCM, or if got exernal AC3 decoder let MPC do that?

Downmix to AC3/5.1, 4.1/Pro Logic, Stereo or Mono depending on audio setting selected in Xbox dasboard.

Some open source project with DTS code: (Maybe code could be used to add DTS?)

Hypercube Transcoder Open Source DTS filter http://hypercube.is.dreaming.org/ (inc. RAW PCM output support) Only support DTS 5.1 yet but plans for 7.1

"BeSure" has VOB/AC3 to CD audio (inc DTS) conversion. http://dspguru.doom9.net/

DTS / AVI Filters - allows AVI/DTS muxing and playback http://www.doom9.org/Soft21/Filters/test.rar

BeSweet - Audio Transcoder (inc DTS decode support) http://dspguru.doom9.net

More info on DTS muxing can be found here http://forum.doom9.org/showthread.php? s=&threadid=41052

VideoLan 10 Feb 2004+ now also has a DTS software- decoder:

"First release of dtsdec (10 Feb 2004) dtsdec is a free DTS Coherent Acoustics decoder. DTS is a high quality multi- channel (5.1) digital audio format in use in DVD's and DTS audio CD's. The code for dtsdec is still in early development stage, but it is already quite useable. VLC media player becomes the first Open Source application able to play DTS audio"

Though their claim of first to open source this is not correct ;)

FYI, libdts was just now a few hours ago added to FFmpeg so it will then likely be implemented into MPlayer soon too, (but think probebely not until after they released MPlayer-1.0pre5)
