Anyone have any experience with installing a Lite version or have a batch script that can unregister all the unneeded filters except for the one eacto needs?

Also curious, do people have scripts that load/unload filters based on tools that may need them? That way, they are loaded when needed and removed when task is completed.

I suppose that maybe eacto is coded to strictly build its graph manually to force its use of a specific filter. But I am not well versed in all this graph, DS Filters, codecs to know for sure. I just know that installing one program can hijack another programs use of its filters that it installed for a specific task. What a nightmare - DLL hell for codecs
Jom covered some of that here:

Also, see post #8037 and 8041
http://forum.doom9.org/showthread.ph...55#post1242555

As for codec hell, that's what a good configurable player such as MPC-HC is for.

Although others like PowerDVD will only use their own anyway.

Installed the latest update to Nero 7 7.11.10 and how when I run -test I receive the following message\

Nero Audio Decoder (Nero 7) is not working correctly
http://www.nero.com/eng/store-blu-ray.html

Nero works fine since I am able to use Nero Vision to playback a .ts file with h.264 video and DD 5.1 audio

Not entirely sure what to do now. If I continue to use -libav what sonic compromises, if any, am I having to make?

Thanks

Select your preferred downmix
Code:
function Dmix3Stereo(clip a)  # 3 Channels L,R,C
{
  flr = GetChannel(a, 1, 2)
  fcc = GetChannel(a, 3, 3)
  return MixAudio(flr, fcc, 0.5858, 0.4142)
}
function Dmix4lStereo(clip a)  # 4 Channels L,R,C + LFE
{
  flr = GetChannel(a, 1, 2)
  fcc = GetChannel(a, 3, 3)
  lfe = GetChannel(a, 4, 4)
  clf = MixAudio(fcc, lfe, 0.2929, 0.2929)
  return MixAudio(flr, clf, 0.4142, 1.0)
}
NicAc3Source("Bubble.ac3")
Dmix3Stereo
#Dmix4lStereo
Normalize()
And encode with EncWAVtoAC3 v3.0b

I just demuxed Eight Below, purely to see the subtitle information and if the english SUPs contained any forced captions and there's a discrepency between the subtitle track numbers displayed at the beginning of the log and those used at the end to display forced caption info. Here's the log so you can see what I mean:

Video track 2 contains 173195 frames.
Subtitle track 14 contains 947 captions.
Subtitle track 15 contains 1053 captions.
Subtitle track 16 contains 864 normal and 24 forced captions.
Subtitle track 17 contains 892 normal and 27 forced captions.
Subtitle track 18 contains 943 normal and 29 forced captions.
Subtitle track 19 contains 949 normal and 31 forced captions.
Subtitle track 20 contains 694 normal and 21 forced captions.
Subtitle track 21 contains 947 normal and 27 forced captions.
Subtitle track 22 contains 945 normal and 30 forced captions.
Subtitle track 23 contains 952 normal and 29 forced captions.
Subtitle track 24 contains 923 normal and 31 forced captions.
Subtitle track 25 contains 889 normal and 20 forced captions.
Subtitle track 26 contains 23 forced captions.
Subtitle track 27 contains 25 forced captions.
Subtitle track 28 contains 27 forced captions.
Subtitle track 29 contains 29 forced captions.
eac3to processing took 23 minutes, 43 seconds.
Done.
As you can see, at the beginning of the log, the subs are listed as using tracks 13-28 and indeed, these are the numbers used in the filenames of the demuxed subs but right at the end of the log, subtitle tracks suddenly go from 14-29, is this a bug?

I try to make a batch file to convert DTS sounds in MKV to AC3 640kbit/s.
Code:
mkdir temp
cd temp
..\eac3to.exe ..\%Input% -demux
..\eac3to.exe *.dts *.ac3 -640
..\eac3to.exe *.h264+*.ac3 %Output%
The demux works fine but then I get :
Code:
Source file "*.dts" not found.
Source file "*.h264" not found.
I think I cannot use the * character. How can I make that ?

___________

Why can't I demux a MKV file in an another output folder (ex: eac3to.exe video.mkv temp -demux) ?
Quote:
C:\Documents and Settings\User\Desktop\eac3to>eac3to.exe video.mkv temp -demux
MKV, 1 video track, 2 audio tracks, 2 subtitle tracks, 1:38:42, 23.975p
1: V_MPEG4/ISO/AVC, English, 1280x528p (80:33)
2: DTS-ES, English, 5.1 channels, 24 bits, 1509kbps, 48khz
"DTS"
3: AC3 EX, French, 5.1 channels, 640kbps, 48khz
"AC3 5.1"
4: S_TEXT/UTF8, French
5: S_TEXT/UTF8, French
Track 2 is used for destination file "temp".
This audio conversion is not supported.

Thanks for your help! You're always the man with the downmixing scripts!

Quick question though. I currently have EncWAVtoAC3 2.0, and am trying to find 3.0. The official site seems to be down. Do you have a good mirror? For now, I will just use the handy-dandy SoundOut avisynth plugin, but I'd like to update EncWAVtoAC3.

Thanks again!

link.

Would suggest to try something similar to the above link. As that's obviously a HD source with re-encoded video, why didn't you convert the audio at the same time as encoding the movie?

Bug in chapter detection

Today I looked at my new Vantage Point BD and eac3to reported 51 chapters. This movie has 16 chapters so on a hunch went back to an earlier version of eac3to and sure enough, got 16 chapters. After trying subsequent versions I found that it broke going from v2.65 to v2.66:

Code:
eac3to v2.65
command line: eac3to h:\bdmv\stream\00011.m2ts
------------------------------------------------------------------------------
M2TS, 2 video tracks, 7 audio tracks, 15 subtitle tracks, 1:30:05

5: AC3, French, 5.1 channels, 640kbps, 48khz, dialnorm: -30dB
6: AC3, Spanish, 5.1 channels, 640kbps, 48khz, dialnorm: -30dB
7: AC3, Portuguese, 5.1 channels, 640kbps, 48khz, dialnorm: -27dB
8: AC3, Thai, 5.1 channels, 640kbps, 48khz, dialnorm: -27dB

2: h264/AVC, 1080p24 /1.001 (16:9)
3: h264/AVC, 480p24 /1.001 (20:11)

A peek at the changelog shows the likely culprit:
Code:
v2.66
* changed eac3to to allow AAC encoding with 7.1 channels (for new Nero encoder)
* fixed AGM creation for files bigger than 4GB
* added support for Nero's new AAC Encoder download URL
* lowered volume of error/success sounds
* when there are 2 similar playlists the one with less chapters is ignored now
Broken all the way to 3.06. Let me know Madshi if I can help in any way to fix it.

Assuming there is only 1 video and 1 DTS track:

Code:
for /f "delims=;" %%a in ('dir *.mkv /b /s') do {
	eac3to %%a 1: %%a.video.mkv 2: %%a.ac3
	mkvmerge -o %%a.DTS.mkv  --language 1:eng --default-track 1:yes -d 1 -A -S %%a.video.mkv -a 0 -D -S %%a.ac3 --track-order 0:1,1:0
	del %%a.video.mkv
	del %%a.ac3
}
pause
Something like that at least.

He said it's broken all the way thru 3.06 at the bottom of his post. He was using older versions to see where the breakage had occurred.

When I started reading his post myself, I thought, why the *heck* isn't he using a version from this century?!?

And who knows, maybe it's the authoring that's wrong, not eac3to! I should not have assumed a Madshi bug when it comes to BD discs!

Support for such older VC-1 MKVs will come in a future version.

In the long run, yes. In theory it's really easy to extract MKV attachments. However, making the eac3to infrastructure understand that there are not only "video", "audio" and "subtitle" tracks, but also "attachments" is quite a lot of work. So it might take a while until I find the time to implement that. Don't know...

Anyone else having similar problems? It seems to work fine for me. Did older versions work better?

Because some of them have sequence headers in the stream and some don't.

That's because eac3to actually decodes the FLAC track during analyzation. I guess I can optimize that...

Might be a good idea, at least to get rid of all these annoying "is it really necessary that eac3to patches it to 24bit?" questions. Will think about it.

however, I'm curious to know if that would produce *exactly* the same video result (frame-for-frame) as, e.g. (assuming track 2 is the video in question):-
eac3to L: 1) 2: video.mkv

would the first 2-step method lose/discard any important information (frame-rate, etc) that the original container used to define the .vc1 stream?
I have read that a raw .vc1 stream is somewhat dependent on its container to fully specify it, so I'm worried that a 2-step process would be lossy in some way?
Both methods should produce similar results, as long as there are no gaps/overlaps in the video track (which is really rare). VC-1 does not depend on the container.

eac3to reports two different things: In the track listing (e.g. if you do "eac3to BluRayFolder") eac3to shows what the Blu-Ray information records say without actually looking at the video data itself. This information *should* be reliable, more so than the back cover, but it could theoretically be wrong. If you actually let eac3to parse the movie file, it checks out the video bitstream. This should be even more reliable (unless there's a bug in eac3to). In your specific case it seems that the back cover is simply wrong.

eac3to currently can't downmix funny channel configurations. It's on my to do list to add support for that, but it doesn't have top priority right now...

Thanks, looks like a clear bug.

You can't just invent your own command line commands. You'll have to live with what eac3to understands. What you could do is "eac3to video.mkv temp\video.*". That will demux into the MKV into a folder named "temp", if that's what you want.

Can you please upload the CLIPINF and PLAYLIST folders? Zipped that should only be a few KBs.

A quick check of the DS Filter chain shows

Not entirely sure what else to check

And I am running Nero 7, not 8.

Here you go--I think 00216 is the mpls of interest and the clpi prolly 00011. Advise if I can provide any further info!

thanks for the reply madshi,

are you saying that one of these 2 methods does NOT remove/compensate for gaps/overlaps - I thought eac3to would always remove gaps/overlaps when demuxing a full-disc-structure title... if this is not the case, which of these 2 methods doesn't invoke eac3to's gap removal...?

or is it simply the case that eac3to does not do ANY Video gap compensation (in any mode - i.e. it just does audio) - I guess if that was the case and that ever happened, eac3to would just flag it in an info/warning message? (never seen such a warning on any of my discs to date anyway) - is it something eac3to might handle in the future?

cheers again,
m

ps - incidentally, does anybody out there know of a way to accurately frameserve (in an AviSynth script) a raw .vc1 file without going to an intermediate .mkv container? I don't think the Haali source file splitter filter will take a .vc1 file as input if I try to build such a graph in graphedit.

better upload it externally, as getting approval can take ages.

eac3to is latest (2.30) and this happens with all libaften builds (generic, SSE3 etc). It also happens when i use as input wav or raw or ac3 files. In other words always. But if i use aften.exe and encode to ac3 outside eac3to everything works fine.

Does it seem as a libaften or an eac3to problem?
I am just starting to use eac3to and have encountered this problem. Is there a fix please?
