 Posted: Tue Dec 28, 2004 5:12 am Post subject: DTS audio on DVDs |
 |
|
| I have two foreign DVDs, one Chinese and the other Korean. Both have DTS audio that I'm unable to play with any hardware DVD player or Linux software player I've tried. Audio works in the menus but not the main features. I did some searching and it seems VLC was once able to play DTS, but the developers removed support after being threatened with a patent lawsuit. So my question is how am I supposed to get audio without dumping/transcoding/etc.? |

Thats odd. I swear I read that mplayer supports it. I have had DVDs that have had only DTS audio and I was also unable to play them. I even tried on my PS2 which is Sony and clearly states it supports DTS (I mean its Sony, why wouldnt it), but still didnt get sound. I just assumed the rips were bad...but I didnt have a change to test it out to prove right or wrong.
I did some googling and here is some reading you might be interested in:

| Mplayer supports DTS (starting with version version 1.0-pre6). Also xine does (not sure from which version, but the latest stable in portage surely does). |

| Verify that you have "dts" in your USE flags for mplayer or vlc. |

The dts support was dropped in 8.0 and later versions of vlc. However, you can still download vlc 7.2 so that's not much of a problem.
Btw, 8.0 ebuild in portage does have "dts" flag. Is dts support removed or not? o.O |

I have vlc 0.8 and DTS works like a charm. In fact it's the only player that I've been able to get DTS to work in.
Thought I think I've missed the "dts" flag in mplayer, I'm gonna test it later. |

Apparently the mplayer-1.0-pre5 ebuild has the dts use flag, but there is no dts support in mplayer until -pre6.

Unfortunately, both mplayer and vlc failed. mplayer32 plays non-dts DVDs, but vlc segfaults with any DVD.

It can be a bug in the MPlayer code _or_ in your drivers _or_ in your

won't help unless you provide this information when reporting a possible bug.

| If you run mplayer -ac help, does DTS show up as "working" in the list? |

Have you tried xine? I have one of thoses dvds and I think xine played the audio. But it isn't a big deal to use dtsdec (from media-libs/libdts) and burn a new dvd...

Don't know about ps2, but most normal dvd players that claim to "support" dts just pass it through to the digital output. Looks like mplayer does the same... |
