Good to know - thanks for the quick feedback!

I assume the front channels are the same, no matter if you decode to 5.1 or to 6.1. You could check this on a working file. So you could take the front channels from a 5.1 decode and the rest from a 6.1 decode. Of course this is not beautiful, but it may be the best solution to treat these cases where it does not work otherwise.

While you are running tests with arcsoft, could you please also test what it does on a 6.1 track when you ask it to output 7.1?
I have more and more BDs with 6.1 audio and I can not play them back properly.

i believe that Sonic will work on such samples, so in that case better to use Sonic instead of Arcsoft. just decode the 6.1 DTS file with both Sonic and Arcsoft and if the two decoded files are different, probably the Sonic decode is the correct one.

hi

madshi you are the best. your prog works very well und your work is great.

a question.

i demux my sourcefiles ever with -demux.
then i get the video-,audistream and all .sups

is there a way to demux all audiostreams and .sups but without the videostream?


hubble

[nautilus7]

No, automatically. You can though choose which streams to demux by using the stream numbers (1:, 2:, 3:, etc) and the proper extension for each stream.

I could probably do that, but I don't really like the idea to add such complicated workarounds for clear bugs in a specific decoder which is still being worked on. Maybe ArcSoft will fix that problem sooner or later? You could report it to their support forum...

Already tried that. The front channels are broken if I ask ArcSoft to decode 6.x as 7.1, too.

I don't see why that should be the case. In my tests the Blu-Ray 6.1 tracks decoded perfectly fine with ArcSoft (as I already said earlier).

Correct. Sonic works perfectly fine for XCh 6.1 DTS and DTS-HD files. However, Sonic doesn't work for XXCh 6.1 tracks, and it also doesn't work for XCh and XXCh 6.0 tracks. Not much of a problem, though, since 95% of 6.x tracks are XCh 6.1.

Just noticed that I forgot to add something to the changelog:

* option "-no7doubling" is not supported anymore
* option "-double7" added which upconverts 6.1 to 7.1

So by default 6.1 tracks are not upconverted to 7.1, anymore. You have to manually activate that if you want upconvertion. Also doubling the 7th channel now also halfs the volume of the 7th channel. Which is what ArcSoft's decoder is doing, too, when it doubles the 7th channel.

[nautilus7]

You have also forgot to remove these options from the command list:

-stripPulldown    strips the pulldown from MPEG2 video tracks
-24p/30p/60i      force the use of the specified framerate for h264 muxing

Right! Removed that now...

That one is still needed. MPEG2 pulldown removal is activated automatically only for m2ts and evo sources, but not for demuxed MPEG2 files nor for VOB or TS sources.

Wasn't aware of that case. Thanks for explaining.

Neither am i; this should be added on the first post i think.

[Atak_Snajpera]

undocumented option -progressnumbers now outputs "analyze:" and "process:"

thank you very much!

Can eac3to demux blu ray subtitles (PGS) and, if yes, what file extension do I have to use?

[Snowknight26]

Yes, .sup.

[nurbs]

Thanks. I tried .pgs and it gave me an error. Also there is nothing about it in the first post so I wasn't sure if it was supported.

You can always use demux to see what extensions are being used, just control c when you have determined what extensions eac3to uses.

Hi. New to this tool. Worked on one DTS file but the second one threw an error ERROR: block code look-up failed
[dca @ 68A532E0]Didn't get subframe DSYNC. It seems to create an ac3 file but I can't test right now.

Also I have Arcsoft Total Media Theater installed but eac3to does not seem to realize it and won't use that decoder. It uses libav instead. Anyway to force it to work?
