eac3to - audio conversion tool

[nautilus7]

I tested tebasuna51's samples with Sonic. The updated list is below:

With the help of Elektra999 I have dts samples with atypical channel map.
The samples was encoded with DTS PRO SERIES SURROUND ENCODER.
Only 3/2.0 and 3/2.1 was encoded with Surcode.

(1) Wrong mask, the correct mask can be easyly put based in detection
(2) When decoded with libav need remapping channels.
(3) Same remap than libav needed.

btw, tebasuna51, is that you on the samples?

I am using your tool to convert TrueHD to PCM and then mux audio and video together using tsMuxeR from ripped Blu-Rays. This works perfectly. I have read so much in this thread and just to make certain that the quality and command is OK. Am i doing it correct, if for instance the truehd audio track is 2 in the 0001.m2ts file:

Convertion from TrueHD to PCM with no loss: C:\eac3to 0001.m2ts 2: out.pcm

Do i need to use the -blu-ray switch? What is it exactly for? I have search this thread and could not find answers to these questions. Is this switch removed for a reason when only executing eac3to to obtain some help?

Thanks again.

You do everything fine. The blu-ray switch is (was) to remap channels to the blu-ray channel order, but you don't need to use it. It's done automatically.

Welcome. One thing I can suggest also, is to add -down16 to the command line if you want to save some space and you don't mind (or you can't hear) the quality loss of the 24 bit to 16 bit conversion. That's of course in case the source TrueHD track is 24 bit and not already 16 bit.

Thanks

As already saint-francis pointed out, you need SUPread to convert HD DVD .sup to Blu-ray .sup, without any OCR. That's because subtitles in these two media are little different.

Since version 2.59 eac3to can also convert HD DVD TrueHD tracks to Blu-ray style TrueHD tracks with AC3 track interleaved. So there's no need to convert to pcm anymore. Except you don't have a TrueHD decoder.

In my case I also have to convert TrueHD to PCM for tsMuxeR to create a correct Blu-Ray structure split into 4gig chunks to be played in AVCHD format on HDD on PS3. As you know tsMuxeR does not do proper TrueHD muxing in blu-ray structure and PCM is a good workaround.

Thanks.

Also look at the tsMuxeR thread;

Thanks for that. This is actually me who posted that and made those tests. Currently there is no solution to mux TrueHD in Blu-Ray structure split in 4 gig chunks due to tsMuxeR problems. TsRemux does work with TrueHD but cannot split the file in 4 gig chunks which is necessary for fat32 disks on PS3 in AVCHD format.

Didnt realize it was you that wrote that

Can you not burn to a DVD-DL in UDF 2.5 ?

Or split before muxing i.e. "split manually" ?

[Duppie]

G_M_C

Yes you can burn to a DVD-DL in UDF 2.5 and it works. But the idea is to take one big (20-30gig) m2ts file open it with a muxer select the required tracks and generate a Blu-Ray structure with one playlist on fat32 (4gig chunks) convert the Blu-Ray structure to AVCHD and play the complete film from HDD on PS3 without writing a couple of DVD's. This requires alot of disk space but it is better than having alot of DVD's and changing the DVD's a couple of times during playpack of one movie.

Wow file playback on the PS3 seems like too much of a hassle. I also do TrueHD/DTS-MA -> 5.1 PCM for my NMT but the only time I have to split the files up is when I'm archiving them to DVD-R Lucky me. I guess if you already have a PS3 a BluRay burner is the way to go. A lot less work.

I use this method as well, it's perfect for rentals that are due back the next day, and you have no time to watch immediately. Also for BDs you have no intention of archiving to DVD9.

The only drawback is you need your own BD burner.

Duppie, do you use AVCHD-ME, or is there something else out there that can produce the same media type... possibly that doesn't cause the slight pause between the 4GB chunks?

Guys, I don't want to be a geek, but your discussion is out of topic.

Remarkably, the WMV decoder is not capable of proper playback of the m2ts, artefacts all over. Ffdshow however, has no problems with the video.

This is a VC1mkv which has always issues with TSMuxer.
I think you remuxed that sample with TSMuxer, did you?

Hmm, getting the weirdest error (see below for full output): "The channel modder was started with incorrect parameters." What is up with that? And how do I fix it? :)

Check that.

EDIT: Sorry i've misssed the source is DTS-HD and libav doesn't work in this case-corrected. Just install TMT trial and give it a go and compare.
