The problem is that eac3to does not remap the channels to Blu-Ray order when exporting to PCM. I guess it should do that?

P.S: Oh, 6.1 channels! My fault. There's just something missing. Will add that to the next eac3to build...
P.P.S: Blu-Ray does not support 6.1 LPCM. Instead it only supports 7.1 LPCM, as far as I know. So should I enforce channel doubling when exporting to PCM?

If the parameters are correct, example:

Pcm2Tsmu input.pcm output_tsm.pcm -c 8 -i 16 -s 96000

(for a 8 channels, 16 bitdepth, samplerate 96 KHz) and tsMuxer accept the audio, can't be a Pcm2Tsmu problem.

@Duppie, if the flac file play properly like madshi say, please use the Pcm2Tsmu thread to post a sample and continue the discussion.

When you say >4GB... tsMuxeR doesn't work. Do you mean it won't accept the .wav file at all, or there will be playback problems after muxing?

^^^It Won't accept the file.

Please use the tsMuxer thread to talk about this problem.

tsMuxer, like other soft, accept the wav but don't play/use the full length.

Converting TrueHD, DTS-MA and DD+ to PCM. Is one library better and more exact then the next? I don't have nero or total media installed and just planned on using the default library.

I want the most accurate conversion available what should I use?

Author has selected the most accurate decoders even you don't have them; so you don't have option B but just an option A which is available on default library

I mean there is no option B in default library.

Having a little trouble understanding you. Are you saying the default library does as good a job as nero or any of the other decoders?

No.
The best decoders are unfortunatlely the commercial ones like nero or TMT which are selected by Madshi as default.
If eac3to can not find those defaults, that time it will use the default ones coming with the library.
For any particular format, you don't have two options since library gives only one default decoder for any particular format.

So for the most accurate conversion from TrueHD/DTS-MA/DD+ to PCM uncompressed I should purchase say TMT?

Is it sooo hard to read the 1st post?

Jeff Flowerday · 19th September 2008, 23:10

Ok I see mention that the default libav works perfectly for TrueHD. What about DD+ though?

The answer has been given on the first post by madshi:

Quote:

default decoders used by eac3to:

MP1, MP2, MP3: libav/ffmpg (free-from library)

(E-)AC3: Nero (commercial)

AAC: Nero (commercial)

TrueHD: libav/ffmpeg (free-from library)

DTS(-HD): ArcSoft (commercial)

So finally Nero 7 + HD-Plugin (not 8 at all) is recommended for DD+ and TMT is recommended for DTS/DTS-HD.... For TrueHD, libav/ffmpeg is recommended which is coming with the library.

And, you don't have to purchase anything; it is up to you. (trust your own ears first; it is a rule.)

Yeah, sounds like a good workaround.

was this ever implemented? i have a bd with a 4ch pcm track (3/1.0 configuration) and eac3to seems to treat it as 2/2.0 when encoding it to flac

In order to make this fully work there are 3 things that need to be done:

(1) eac3to must properly detect the channel configuration. The track could be 2/2 or 3/1. The next eac3to version will detect that correctly for m2ts sources.

(2) FLAC used to not support funny channel masks. But I've seen that there's a way now to store a WAV channel mask as FLAC meta information. So storing 3/1 in FLAC should be possible now. But eac3to will have to read/write that channel mask meta information. I've put that on my to do list, but it might take a while until I find the time to implement that.

(3) The FLAC decoder (e.g. madFlac) must be able to read and interpret the channel mask meta information. madFlac doesn't do that yet.

Thanks. Same problem as with the other sample. Will be fixed by the next eac3to version.

monohouse · 20th September 2008, 15:28

does eac3to allow joining independent mono wav/raw files into a single multi-channel file ? because it seems there are no wave editors that are capable of reading a single 7.1 channel wav larger than 4 GB, while some maybe able to allow the one (larger than 4 GB) but that same program does not allow the other (7.1 channel) and the other way around, there may be one or two programs that do support reading such a file fully (both 4 GB size AND 7.1 channels), but they have other drawbacks (only open first 30 minutes (nero) and others open the multi-channel file and open all the channels as mono separated channels, without support for joining them into a single .wav file (cooledit))

Added fps value to MKV header.

Done.

Everything seems to be fine but after muxing the mkv to TS with tsmuxer (1.8.5) the final ts file shows a different length in mpc compared with the source file (4h for Prestige, ~3h for Full Metal Jacket). Didn't have this problem before with vc1conv and different movies... any ideas what went wrong? tsmuxers fault?

I'm trying now vc1conv again, but this will take time...

Does the mkv video file play correctly? If so then I suspect eac3to is not at fault.

TSMuxer doesn't like vc1mkvs remuxed by haali.
Try to extract vc1 and audio with eac3to and remux with TSMuxer.
If you still want an mkv, try mkvmergegui using remuxed file.

ah, ok. but how to extract the vc1 from the mkv? eac3to gives an error message (The format of the source file could not be detected) on its own mkv

trying now mkvextract... takes a while....

Edit: mkvextract produces an avi, which I don't expect that tsmuxer would load it....

rica · 20th September 2008, 17:34

You must be making something wrong.

Extract vc1 directly from your evo; this is the best way.

(BTW i have lived no any issue extracting vc1 from the mkvs created by eac3to)
