DTS 5.1 to Opus Stereo downmix... #13

Closed krab closed 7 months ago

krab commented 1 year ago

Doesn't work?

I tried to compact DTS 5.1 @ 1509 Kbps into opus @ 320 Kbps stereo (downmix option enabled).

Stream mapping:
  Stream #0:0 -> #0:0 (copy)
  Stream #1:1 -> #0:1 (dts (dca) -> opus (libopus))
  Stream #1:2 -> #0:2 (dts (dca) -> opus (libopus))
  Stream #1:3 -> #0:3 (dts (dca) -> opus (libopus))
  Stream #1:4 -> #0:4 (dts (dca) -> opus (libopus))
  Stream #1:5 -> #0:5 (dts (dca) -> opus (libopus))
  Stream #1:6 -> #0:6 (dts (dca) -> opus (libopus))
  Stream #1:7 -> #0:7 (dts (dca) -> opus (libopus))
  Stream #1:8 -> #0:8 (copy)
  Stream #1:9 -> #0:9 (copy)

It shows that FFmpeg can't downmix properly using libopus, however in staxrip uses opusenc which again uses libopus, and it works no issue, but staxrip uses temporary dst->flac files for that, opusenc accepts flac as input source.

It's complaining about the 5.1(side) channel layout in the source audio streams. It appears this version of FFmpeg doesn't have automatic channel mapping for Opus. Do you absolutely have to use Opus or can you try it with another codec?

Yes, because I want to. Anyway, StaxRip works for now just fine, even tho StaxRip's GUI is a mess.
