is there a way to force eac3to to encode AC3 with libav instead of aften? Justin Ruggles himself said that libav is better than aften and aften shouldn't be used anymore... he should know, since he developed aften and is now involved in libav... is there a way to force eac3to to use it? is there any reason not to use libav by default?

also on a similar matter, any way to get eac3to to use the DTS-HD Master Audio Suite (if you own it) for encoding DTS? would definitely be an improvement to surcode...

I think you can tell eac3to to write to stdout and pipe into ffmpeg or avconv...

If you donate a considerable amount of $$$$$ to madshi, he may think about that feature request ^_^ Seriously, the Master Audio Suite is a Java application, and unless I'm very misinformed, madshi is not a Java enthusiast

Upmix Dolby Digital 2.0 with ProLogic algorithm?

I have a 2 channel track that when played through an AVR will upmix to LCR and a single surround channel. Can eac3to 'upmix' this to individual L,C,R,S wavs?

maxmercy - I've previously requested that they take a look at a DPLII upmix option. There didn't seem to be much interest.

Nope, eac3to can't do this upmix.

You can try Foobar2000 and the plugin foo_dsp_fsurround

I am not certain, but I believe to remember that Selur was interested in such matrices too, it may be avaliable in his "Hybrid" converter.

thanks, I'll try that...

other question still remains, why is libav not used by default in eac3to?

Thanks for the tip. Is there a way that foobar can write a .w64 or WAVEX after upmixing the stereo/prologic source?

The "eac3to and more" GUI does not work well at my Windows 8.1. It looks blown out of proportion and many menus/buttons are hidden. I tried disabling DPI scaling and it still doesn't look right. Is there any way to fix it? Or are there any other GUIs for eac3to that have the same amount of options?

I don't actually use it but I think you can give this GUI a try.

One more thing: I'm trying to get eac3to to extract a 6.1 Discrete DTS-ES stream from a DVD (.VOB) into a 7-channel .dts file with no loss in quality. I have installed Arcsoft DTS decoder, but it will only work when I export it to .WAV or .FLAC (it's still lossless, but the exported files are, of course, unnecessarily large). Is there a bit-perfect method to demux the stream to a 7-channel .dts?

This sounds like you want no conversion at all going on. In this case, the command line is
Code:
eac3to "VTS_01_1.VOB"+"VTS_01_2.VOB" "output.dts"
(or whatever your input files may be). Assuming that, you probably need only select dts as output codec in the GUI and there should be no conversion (I don't use a GUI myself, so I'm guessing here, but it should work).

No such luck. I used this command, both with eac3to and the USeac3to GUI, and the resulting .dts file is 6-channel.

How certain are you that the dts audio stream in the VOBs actually is 6.1 DTS-ES, and that the demultiplexed file is not anymore? Which tools did you use to check their properties?

Please put the extraction log file and the info than show UsEac3to when load the extracted dts.

Oh, my God! I was wrong. The resulting .dts DOES have the seventh channel as well, according to MediaInfo. Whoops. Thank you for your help, guys!

Because it seems there's a Front channel too but eac3to always extracts it as 2.0 Stereo FLAC.

It says it is 2 channel though.
