MeGUI: bug reports and feature requests

[Poutnik]

Have you considered integrating of ProjectX among the tools set as preindexing step ?
It is useful for DVB-X origin sources, performing MPG PS/TS demuxing to M2V + MP2 or WAV, together with fixing DVB transmission errors and related A/V sync errors.

[Poutnik]

There is an interlace related source type analysis in AVS source creator.
It works well, but seems to me corrupting the processing work-flow.
It should be done after cutting e.g. by AVS cutter, not before.

If the source is DVB capture, present advertisements are often interlaced, but movie itself is progressive.
At AVS creation steps, analysis will mark the source as partly interlaced, but the interlaced parts are cut at the following cutting step.

So I think the analysis should be within MeGUI moved somewhere else.

Edit: OR - the cutting invokable within AVS creator, before running analysis.

            this option restricts or enforces x264 parameters if necessary
     [x264] several adjustments
2014 [OggVorbis] removed channel remapping as it is not needed anymore
2013 [M2TS Muxer] fixed splitting option. Bug #3294210
                  fixed m2v input handling
2012 [File Indexer] disable Audio group box when FFMS is used because this indexer cannot extract audio streams

Thanks for the updates!


Edit:
PSP profile not working. B-Pyramid needs to be disabled in order for the video to work.

Personally I can live without the target playback device option since it can't be modified by the user and new profiles cannot be added by the user also.
It's like a profile within a profile.

There will be no device preset anymore from the update server. The checks are much more comprehensive than the old device presets. It is still possible to create own presets of course.

So there won't be any more MeGUI presets updates from the server?
The device presets in the x264 dialog will be fixed by the dev and the user can only add custom MeGUI presets?

If so, I feel that only widely used device preset such as blu-ray, AVCHD, DXVA, DivX Plus HD, etc should be included in the x264 config dialog.
Including the preset for G1, N8, N900, etc feels like a waste of space.

megui device presets are no longer necessary since x264 now includes devices presets. megui will support them as it is know to support the other x264 options (read as: it will support most or all of them). just configure the encoder from the config window and select the device you want to play the video on.
so, yes, they will be ADDED by the devs (im still confident i can be back working on the megui source... one day...) as long as they're an x264 option. on the other hand you can still create specific device presets setting the encoder advanced options accordingly to the device needs.

[Lighto]

@Sharktooth
So MeGUI devs are more or less preparing for x264 devices presets by including the devices drop down list in the x264 config dialog.
When the presets are ready, the devs can simply update with the device preset switch. Is that right?

[Zathor]

Yes, that is correct.

The new system even gives more flexibility in the limits of a specific device as the old system as the settings are not fixed anymore. e.g. the reference frames are not fixed anymore to 4 (for Blu-ray) - instead based upon the x264 preset, the video source / resolution, the user chosen value, ... the best value will be used and therefore may vary between 0 and 6.

[Lighto]

When custom --sar command is added to the x264 config dialog, the command line in the log defaults to --sar 1:1.
Is that meant to work this way?
The force SAR gui works fine though.

[Zathor]

I need to have a look at the problem. At the moment I can only say that there is a bug report describing a similar problem: http://sourceforge.net/support/tracker.php?aid=3300094

[QBhd]

I am still wondering why the M2TS bitrate calculations are still broken... can't you just take the formulas/codes from version 0.3.5.0 and put them back in to the latest build? Currently I am using the latest MeGUI, but I have to use 0.3.5.0 to find the bitrate, change my preset and then not target a filesize in my output.... 0.3.5.0 is much easier to use, but I like/want/need the features of the latest build.

I filed that bug report. Doesn't matter if I use a custom command line sar or use the pulldown "Force SAR" option... all encodes are forced into --SAR 1:1

Thanks for looking into it.

PS - I wish the Force SAR also had "--sar 4320:4739" and the other ratio for 16x9 (whatever the numbers are - sorry, I don't have them memorized).

not sure of this is for just bugs, or issues aswell....anyway, i have noticed that a lot of performance is wasted when MeGUI is dealing with the audio.

only 1 core (1 thread) is utilized, even when doing 2 audio tracks.....

MP3 encoding and AAC encoding can take a good 8 minutes on my system, however with all four cores being used, just over 2 minutes....

have noticed some other inefficiencies aswell....i am aware that MeGUI is open source and must use secondary applications that are too open source (most of which are quite old), even so i thought i would share this if it hasn't been shared already.

it came to me the other day when i was converting a 3.2 hour long film.... the audio (3 tracks- 1 main - 2 Commentary) took 40 minutes to do, that when i felt i should at least share my thoughts.

i guess programs like Azids/ MP3 Lame are just..... old i guess when it comes to multi-threading, strange that these programs haven't been replaces with superior versions (multithreaded from the ground up)

anyway, great program, starting to get the hang of it..... a lot of stuff to digest, a lot of window swapping (finding it difficult to get use to jumping from one dialogue screen to another....) but getting there. still get the feeling of CHAOS sometimes, have to close program and start fresh just to shake that feeling.

Nothing to comment to my 2 posts form May 5th and 8th ?

This could be eventually generalized to custom toolset item.

Just added this bug to the tracker at SF. I know how you guys love those international bugs, ANSI code page vs Unicode UTF-8, annoying little bugs and errors.

I wonder why none of the other Eastern European folks mentioned this error before, is it because it's something special with the system I'm temporarily using here that's set to one code page (Serbian) but users characters from another one (Polish)?

SourceForge.net > Projects > MeGUI > Tracker > Bugs >
Mux Error Due To Eastern European Letters in Video Filename

When the input file includes Eastern European (Polish) letters in the file name the mux job will fail with error since the video stream file will have empty boxes instead of those characters (e.g. Ą ą Ć ć Ę ę ł Ł Ń ń ó Ś ś Ź ź Ż ż) in the file name. (Polish Alphabet: http://en.wikipedia.org/wiki/Polish_alphabet )

The Windows XP system is running with the Serbian (Latinic) code page selected in the Control Panel, Regional, Advanced settings as the default code page. The Microsoft Windows XP Serbian Language Pack (freely downloadable from Microsoft) was applied to the current system to turn all prompts into Serbian language.

It appears that the output in the Log tab in MeGUI also shows the empty boxes instead of the letters. It appears that in MeGUI the .AVS input script line FFVideoSource() is the one that shows the problem first with the missing character.

--[NoImage] FFVideoSource("C:\Documents and Settings\User\My Documents\My Videos\Czterej Pancerni i Pies\Czterej Pancerni i Pies - 01 - Za�oga.mp4").AssumeFPS(25,1)

However, when then actual .AVS file is opened in Notepad the characters show up correctly and the file is in ANSI format.

I could use czech filenames, but I do not try fortune and make filenames for processing chain de-spaced and ASCII friendly.

This is done on purpose. I REPORTED a while ago that audio encodings would randomly get messed up when running 2 audio encoding jobs at the same time using avisynth.
