MeGUI: bug reports and feature requests - Page 60

i've run into the following issue trying to downmix + slow down 3.1 ac3 tracks to 2.0 ac3. i ended up with 3.1 encodes instead of 2.0. tried two similar source files. all relevant info (hopefully) given below. megui updated yesterday to all development updates.

The downmix only work for ac3 5.1

You can create a specific avs file to downmix others channels configurations, for instance:

Code:

LoadPlugin("C:\Program Files (x86)\MeGUI\tools\avisynth_plugin\NicAudio.dll")
a=NicAc3Source("D:\SomePath\SomeAudio01\SomeAudio01 T82 3_0ch 384Kbps DELAY 0ms.ac3")
flr = GetChannel(a, 1, 2)
fcc = GetChannel(a, 3, 3)
lfe = GetChannel(a, 4, 4)
clf = MixAudio(fcc, lfe, 0.2929, 0.2929)
MixAudio(flr, clf, 0.4142, 1.0)

And input the .avs to Megui instead the ac3 file
Include the slowdown (if you need) and normalize after.

The downmix work fine for the first sample (L,R,C,LFE), with the second (L,R,C,S) you need this mix:

Code:

flr = GetChannel(a, 1, 2)
fcc = GetChannel(a, 3, 3)
lrc = MixAudio(flr, fcc, 0.4142, 0.2929)
sl  = GetChannel(a, 4)
sr  = Amplify(sl, -1.0)
blr = MergeChannels(sl, sr)
MixAudio(lrc, blr, 1.0, 0.2929)

thanks so much tebasuna51, i'll try that right away.

also i have a totally stupid question: i don't understand the sample02 chan configuration: L C R, Side: C; what is "Side: C"?

Edit: i just tried this second sample in Ac3 filter it shows left, center, right and.. SL (side left), what kinda weird configuration is that? could it be a broken (in some way) audio track?

A wrong translation:
L C R S (acmod 5 in ac3 header) means:
Left Center Right Surround

equivalent (after remapping) to wav channels
FL FR FC BC
FrontLeft FrontRight FrontCenter BackCenter

If you don't have a Back Center speaker a proper player must play the BC in BL-BR

Vincent Vega · 26th June 2010, 07:03

so if AC3Filter plays the Surround channel in SL only it's a bug in it? i've always liked valex's decoder so much.. what ds filter would you recommend that can handle such chan config properly?

I always recommend use ffdshow instead AC3Filter.
With ffdshow you can remap (matrix mixer) the BC to BL-BR with 0.7071 coefficients.

ok thanks for your time man.

Welcome back!

Sharktooth · 29th June 2010, 15:01

it seems you did a huge work zathor. thank you.
i guess i have to study the latest sources almost from scratch.
feel free to contact me and, obviously, give me some days and i will be back developing megui

JoeH · 30th June 2010, 08:00

Good to see you back Sharktooth.

Taurus · 30th June 2010, 11:23

A warm welcome back Mr. Shark.
Where have you been so long?
So maybe Zathor & Shark = the new dreamteam?
I really appreciate your work on MeGui

flebber · 30th June 2010, 11:36

Has anyone else had trouble in megui with Warpsharp.dll and toon.dll.

I removed both dll's and my megui encodes perfectly. I replaced warpsharp.dll with the version from warpenterprises and it stopped the error.

But I re added toon.dll to my avisynth plugins and it cannot complete an encode with the toon.dll being used. Does anyone have a light toon/anime dll that plays well with megui. I haven't had to encode much anime previously.

Sharktooth · 30th June 2010, 13:22

@flebber: it seems an avisynth problem more than a megui problem... try to find newer version of the toon plugin.

@Taurus: thanks, i had "troubles" of all kinds...

@JoeH: thanks

quantum5uicid3 · 30th June 2010, 13:49

changes to --level and --profile in their new location do not update the commandline below until after you close and save the x264 configuration dialog. and i still think they should be basic x264 settings.

edit
and i dont think the threads checkbox or field is working. nvm i think it's just doing the same thing as level and profile.

Sharktooth · 30th June 2010, 13:52

i think i read somewhere zathor is working on the x264 configuration window.

saint-francis · 30th June 2010, 20:57

Sharktooth, I am very glad to see you back!
I hope you health is up to speck and that all else is well with you.

quantum5uicid3 · 1st July 2010, 15:37

some fixes to profiles. ***for latest x264***
1. added "--open-gop coded" to bluray and avchd presets.
2. force disabled bframes and soft enabled CABAC for iphone profile.
3. force disabled b-pyramid and soft enabled CABAC for psp profile.
3. and removed redundency of setting vbv to 10000 when level 3 is already set. *correction*

md5: 75f2898b57f84b501ab92b2d0c31161a

addition
i packaged ffm2-312 for the update server too just in case you hadn't had time. it seems stable.

edit2:
wasnt thinking and disabled bframes completely on psp

also, the motorola droid supports --level 3.1 --profile baseline --ref 5 @ 856x480

Whoa, Sharktooth is back! Glad to see you! Has your health improved then??

Sharktooth · 1st July 2010, 18:48

im pretty good and recovering well but my health is OT here
however, thanks
