MeGUI development

[terminate]

I am not absolutely sure, but I have the feeling that since a couple of updates MeGUI, (using version 0.3.1.1011 at the moment), is always normalizing the Peaks, (e.g. to 100%), even if I have not checked the "Normalize Peaks to ..."-Checkbox in the audio configuration dialog.
This seems to happen with all audio profiles, (only tested with Nero AAC and lame .mp3 profiles). Can anybody confirm this behavior?

As I said, I am not absolutely sure but I do not remember that MeGUI did any changes to the volume, lets say, half a year ago.

When there are a downmix (5.1 -> 2.0) a Normalize is added always. To avoid clips the downmatrix coeficients must sum 1.0 but this can cause low downmix volume and the Normalize pass is recommended.

The stereo presets have Downmix and Normalize activated.

Yes it has something to do with the "Output Channels"-setting in the audio configuration dialog. To keep the original peak levels from a stereo source track in the encoded audio track it is not sufficient to just uncheck the "Normalize Peaks to ..."-Checkbox you also have to select "Keep Original Channels" in the "Output Channels"-Setting!

Suggestion: To avoid misunderstandings the "Normalize Peaks to ..."-Checkbox should always be checked and greyed out if the user have selected an "Output Channels"-Setting that is different from "Keep Original Channels".

Edit:
In the mp3-"configuration dialog" there is no "Keep Original Channels"-Option in the "Output Channels"-Setting, does this mean that there is no possibility to avoid peak normalizing when encoding stereo tracks to mp3?

[tebasuna51]

MeGUI try to be easy to configure and offer only the options more frequent. For user than need more control to transcode audio you can use BeHappy or, best, you can write your own avs. Both, MeGUI and BeHappy accept avs files to transcode.

If you put Downmix to stereo with a source stereo, yes the Normalize is applied.

Thank you for your answers! Nevertheless, personally I definitely would consider the possibility to convert "standard"-stereo tracks into aac or lame-mp3 tracks without any peak-normalization at all, as a very frequent required option. Simple example: If I wish to encode single songs from the same concert, even the "mostly harmless" peak normalization could disturb the dynamic differences/relations between the songs when played together in the same playlist afterwards.
I also agree with you, that MeGUI should be as easy to configure as possible, but I always had the impression that MeGUI is that one application that always tries to balance very well between the ease of use and still offering as much options as possible compared to other encoder GUIs.

I put my first question into the "MeGUI development"-Section, because I thought it would be a simple bug which somehow crept in between several updates of MeGUI, (didn't recognize until now, that there seems to be no simple setting to encode stereotracks to mp3 in MeGUI without peak normalization), but now that I see that this may be a general / feature request topic which may not belong into the "MeGUI development"-Section, its ok to stop the discussion in this place.

At least my wish: "I would like to be able to encode stereotracks in MeGUI to aac or lame-mp3 without peak normalization by using standard options in the audio configuration dialog".

You are right and I don't read your EDIT comment, sorry:

I was thinking the option was accesible.

Then I second your petition, the option "Keep Original Channels" must be a option also for stereo output.
Does make sense the Downmix for a stereo input.

[Kurtnoise]

done in rev 990...

@Sharktooth: an update (http://www.mediafire.com/?my4etzdzz2y) for LAME presets...

[b66pak]

do you plan to support creating of .avs files from .dga (dgavcindex files)?

and .dgv files.. please.

currently megui crashes without any error if i open an avs file with .dgv index.

[Guest]

and .dgv files.. please.

currently megui crashes without any error if i open an avs file with .dgv index. Really? MeGUI 0.3.0.2015 works fine for me. Make sure you start the CUVID server fresh before opening MeGUI (no stuck ones in the task list), and close the preview right away.

ok, maybe that was my mistake i opened megui 1st.

why close the preview right away..? just curious. :)

[Guest]

The CUVID server cannot support multiple simultaneous decodes, and the preview counts as a decode.

Thank you very much for supporting my petition tebasuna51! And of course, thank you very much too Kurtnoise (my hero!) and Sharktooth for doing the work! (I really have to find out how to do an anonymous donation to the doom9 donations account!)

Greetings!

[Sharktooth]

you should really thank kurtnoise. i just made the build.

[Romario]

Dear Sharktooth, please give me download link to 0.3.1.1012, again not have download link, as usual. :(

Why it's so hard to post unstable MeGUI versions here, http://sourceforge.net/project/showfiles.php?group_id=156112

[Sharktooth]

is it that hard to use the autoupdate feature?

Is the Corrupt Memory error going to be fixed in the new build? A few more people I know claim to have this error. I am able to delay the error by clicking "OK" to a certain point only. On adding filters and previewing the script, the error keeps on popping on every click on the meGui interface. Hope this is fixed or a workaround is posted soon.

Thanks for the great application, developers! :)

PS: Not asking for help here, but just informing the developers about this issue.

this isn't working. unable to select a parameter after ticking the option.

[Kurtnoise]

oops. Sorry...fixed. :)

Hi guys,

thanks again for your hard work.

Really, MeGui is getting better than better day by day :thanks:

[lexor]

- (kurtnoise) [OSInfo] add x86/x64 platforms detection.
Will this be used to download x264 builds appropriate for our system (now that 64bit windows support has been committed), or do we still need to manually override the .exe?

[Kurtnoise]

for the moment, yes, you need to overwrite it manually...

detection is displayed in the log actually.

[Kurtnoise]

@ateeq : if you have some time, could you look at issues #2606513 & #2602264 This is the same thing (this concerns the one-click encoder). Yesterday, I digged it but unfortunately, one problem remains (fact is there are 2 issues - first one about null string for filename [easy to fix] & another one, completely unknown to me) and I've no idea why. Quite strange though...

[Sharktooth]

0.3.1.1016

- (kurtnoise) Rename mux to muxer for project files.
- (kurtnoise) [OneClickWindow] the workaround was a bad idea after more testing & digging...

[Kurtnoise]

I'm tired to read nth time the same thing (seems that some people don't know that a search function exists...dangg) about the last x264 build error. So, to fix it, grab the last one (32 bits) from here (http://x264.nl/). That works...

[Sharktooth]

ill revert it back to rev1113.
however it works here.

[Sharktooth]

i uploaded a new x264 rev1114 build in the autoupdate server. please test if it works on 64bit OSes.

new update works fine with Vista 64 dual core. :thanks:

[needsoft]

The new version works fine at my vista64.

[QuadraQ]

I like to take my original source and output it to several different formats (1080p, 720p, 480p). Sometimes that involves using MeGUI to do some simple cuts. All the tools are there - I open the AVS Cutter window, and save the cuts to a file. However, when I create a new AVS file for the next format I want to process, there doesn't seem to be a way to load the cuts file again. Since it's the same video, just at a different target resolution, the cut points don't change and should be reusable (on large video it takes some time to find the right cut points). Am I missing something? Would this be difficult to add?

[Sharktooth]

this is the megui DEVELOPMENT thread...
for troubleshooting look here: https://forum.doom9.org/showthread.php?t=105920
feature requests must be posted in the feature request tracker on the megui project page on sourceforge.

[QuadraQ]

Sorry, didn't realize you have a sourceforge homepage. I'll post the feature request there.

[Inspector.Gadget]

@MeGUI Developers - In light of this problem (http://forum.doom9.org/showthread.php?t=145262), does it make sense to have the AVS Script Creator use DirectShowSource by default for AVI input files?

[Kurtnoise]

nope...

[squid_80]

That's an ffdshow issue, not a directshowsource issue.
