You actually answered your own question there, wavs is the right answer.

eac3to input.file output.wavs

I demuxed with tsremux, and muxed with tsmuxer so I don't think it's related to a specific program?

tsmuxer won't accept the pcm output from eac3to, so that extra header is what it needs. could the header be related to the m2ts container it came from?

why does it remap channels ? I wasn't awear that remapping channels was required, is the process losses data ? is it possible to avoid both of the processes ?

endian swap is just a re-ordering of the bits different people use different endian, so it's needed to swap between them.

same thing with channel mapping, some people use different order.

well you have the exact same number of bits, they are just in different order.

the AVC video track of the 'things we lost in the fire' is indicated as a 16:9 track with pulldown flags. is this of any importance for me when I just want to remux the movie? so far I just remuxed it as usual and it also looks normally, but I just want to be sure.

Wow! Thanks a lot! I would never figure it out by myself! Well it's obvious and not obvious at the same time.

I think it was fixed in 4.3, but I'm not 100% sure.

I just got 4.3 and I know you can do multi mono WAVs -> LPCM for sure.

Hey madshi!

Thanks for your continuing work on eac3to. You have developed it into one helluva tool!

This week I've been working on converting the Galactica Season 1 HD DVDs to BluRay, using eac3to for audio and EVOdemux + vc1conv for the video.
The VC-1 video processed like this is recognized by tsMuxeR as 1080p @ 23.976 fps and the remuxed BluRays play back perfectly smooth in PDVD 8 at a refresh rate of 2x 23.976 Hz.

So I thought I'd give eac3to a go on the video front, too, and had it demux and remove the pulldown flags. The resulting vc-1 file is recognized by tsMuxeR as 1080i @ 23.976 fps and what's worse, playback got really jerky about 17 minutes into the episode I tried.

Is it so that eac3to only removes the pulldown=1 flag but leaves the interlaced=1 flag in place? And if that is the case, would you please be so kind as to correct it?

TIA!
S.

I have a question:
Eac3To reportet this:

1) 00120.mpls (angle 1), 00152.m2ts+00153.m2ts+00154.m2ts, 1:26:15
- h264/AVC, 1080p24 /1.001 (16:9)
- AC3, English, multi-channel, 48khz
- AC3, German, multi-channel, 48khz
- RAW/PCM, German, multi-channel, 48khz
- AC3, English, stereo, 48khz

2) 00120.mpls (angle 2), 00152.m2ts+00155.m2ts+00154.m2ts, 1:26:15
- h264/AVC, 1080p24 /1.001 (16:9)
- AC3, English, multi-channel, 48khz
- AC3, German, multi-channel, 48khz
- RAW/PCM, German, multi-channel, 48khz
- AC3, English, stereo, 48khz

3) 00037.mpls, 00004.m2ts+00005.m2ts, 0:22:50
- MPEG2, 480i30 /1.001 (16:9)
- AC3, English, stereo, 48khz

4) 00004.mpls, 00004.m2ts, 0:15:14
- MPEG2, 480i30 /1.001 (16:9)
- AC3, English, stereo, 48khz

What I must use in the commandline, to use: 2) 00120.mpls (angle 2) ??

[nautilus7]

Type the command you typed to list the above plus 2) at the end.

See my example here for details.

Here you can see where madshi says that vc1conv is better than eac3to for removing pulldown and temporarily disabled -stripPulldown. You could go eac3to > vc1conv > tsMuxer and save a step. This will get you 1080p @ 23.976.

[BlackJack1]

I can not drag'n'drop eac3to app. and hddvd/bd files to cmd window on Vista system on my laptop. Do you know how to fix it? In desktop machine with WinXP - no problem...

@nautilus7:
Thx !!

Somebody has succesfully converted the Movie "Open Season"?

The Movie is 00152.m2ts + 00153.m2ts + 00154.m2ts.
or in German 00152.m2ts + 00155.m2ts + 00154.m2ts.

But the change from 00152.m2ts to 00153/00154.m2ts is not clean. My standaloneplayer (popcorn) hangs at the change.
At Windows-PC with Powerdvd is not better. It stops a short Moment and than goes on with playback.

I testet all:
- copy /b 00152.m2ts + 00153.m2ts + 00154.m2ts
- demux and mux with TSMuxer
- demux with eac3to (playlist) and Mux with TSMuxer
- convert to MKV

Somebody can help?

[nautilus7]

Can you post the eac3to log? Re ripping the disc could make the trick.

Thank you. That was an older version and I thought perhaps in the meantime things were improved.

Right - that's what I did in the end. It's just that with eac3to -removePulldown we would be able to save another step. When I'm converting episode after episode of TV series I'm grateful for every chance to streamline my workflow.
The batch creation of eac3to_more_gui is heaven-sent in that regard btw.

Hiya everyone,

I am currently using EAC3TO GUI (Keymakers version) and noticed that one of the options is video quality which spans from quality 0 to quality 4....can anyone tell me the differences as I am trying to make the mkvs smaller but do not want to sacrifice too much quality.

[nautilus7]

From 1st post:

-quality=4 slowdown/speedup/resampling quality (0 = low; 4 = very high)

So, nothing to do with video. Probably a bug. My advice is to use the new eac3to gui, since it's up-to-date.
