#16933 new bug

DTS audio stream distorted

Reported by: miqlas Owned by: stippi
Priority: normal Milestone: Unscheduled
Component: Applications/MediaPlayer Version: R1/Development
Keywords: Cc:
Blocked By: Blocking:
Platform: x86-64

Description

It is hrev55064, x86-64 Haiku.

I plaing VOB files in MediaPlayer. The VOB file contains 3 stream according to FFMPEG:

  • Video : OK
  • Audio 1 : DTS, 48000Hz, 5.1(side), fltp, 1536kb/s : DISTORTED
  • Audio 2 : pcm_dvd, 48000Hz, stereo, s16, 1536kb/s : OK

DTS audio stream distorted, and while it is still in sync with the video, it is almost unrecognizable, like demons talking or something like that. So it is not a wrong channel redirected to the output (like bass chanel to the front channels), but the audio stream decoding is not ok.

On the vu-meter only 2 channel shows activity while playing the DTS stream.

The disk used for this test: Michael Bolton - Live at the Royal albert Hall

Interestingly VLC doesn't even lists the DTS audio stream.

Is the DTS channel the first one and MediaPlayer starts with it, or do you manually choose it? In the second case it may be a problem in decoder/buffers/nodes/whatever reconfiguration on track change, not something DTS-specific.

I've downloaded an mpeg with 4 audio streams: 3 stereo, the other one 5.1(side). They are all ac3, but I see the same behaviour you get when selecting the 4th track. Then I changed MediaPlayer to start with the last track and it sounded right, with activity in all six channels, and the noise coming back when I chose any of the stereo tracks.

DTS is the first audio stream, picked automatically by MP.
