MeGUI Bug-Report Thread

[spunch]

I have a problem with MeGUI that's been around for quite a while and I feel like I need to report it.

I use the OneClickEncoder feature of MeGUI a lot, but I don't use it for single videos, I have a batch script that generates many OneClickEncoder jobs for many short clips. The problem is MeGUI doesn't handle so many OneClickEncoder jobs at a single time very well.

I tend to get many errors (and eventually a fullscale crash) in the OneClickEncoder innitiation routine - when MeGUI creates many jobs out of the OneClickEncoder job (the time when MeGUI also decides which deinterlacer to use, cropping, etc...).

I get these errors when I have more than 15~ OneClickEncoder jobs in the queue and MeGUI processes them sequentially.

To get around this problem I simply suspend/pause all the OneClickEncoder jobs after 15, and let MeGUI process the first 15. I then restart MeGUI, unpause the next 15 in queue, and I continue this cycle until everything is processed. Not very convenient but it works.

I think MeGUI needs to reset something in itself after every OneClickEncoder job to avoid these errors and crashes.

The sort of errors I get:

Source detection failed
Eroor opening analysis script External component has thrown an exception.
Check to make sure you have TIVTC.dll in your AviSynth plugins directory.

Hi,
Where is the "use mencoder to xvid " option ??

I hate xvid_encraw, and like to use mencoder ;-(

[Adub]

they are under the settings menu. It is a drop down list. There is also the option to use Mencoder instead of x264 commandline as well.

[bratao]

Merlin7777,
i know this and always use mencoder,
but the lastest version(0.2.3.2167) do not have it !

[berrinam]

What is wrong with xvid_encraw that makes you not want to use it?

[acrespo]

My AVS scripts can't be recognized by xvid_encraw. I already post my script here and nobody can explain this problem.

[ChronoCross]

There is nothing wrong with xvid_encraw. I'll take a look at your script and see if I can narrow it down.

P.S. mencoder currently doesn't work using the latest avisynth versions. Which is why it is a bad idea to use it.

Repost the avs that is giving you problems. I can't seem to find it.

[acrespo]

The latest megui stable version work with mencoder perfectly to me.
I have avisynth 2.56 installed here. I don't know if this is the reason for my xvid_encraw problem.

[ChronoCross]

2.5.7 doesn't work with mencoder due to mencoder being broken. something about planar alignments (I forgot exactly what the problem was).

xvid_encraw should function correctly for all versions of avisynth currently in use. what problems are you having that you think it's broken?

[berrinam]

I know this is annoying, but all I can say is that, since MeGUI is in a managed language (C#), this is probably AviSynth's fault. Maybe someone else can help more. I'll look into it in a little while, though, to see if anything obvious crops up.

[berrinam]

3-) XviD encoding is wacko it seems. No matter what quantizer you enter (CQ mode), it always uses 8. Also, some checkboxes don't work--that is, even if you check Cartoon Mode, when you hit OK, it is then automatically unchecked. Thus, every encode I do is forced into Q8, and many options can't be selected--no cartoon mode, no chroma optimization, etc...
Whenever you have a problem, the easiest solution is simply to hide it. The options which didn't work are hidden (because they aren't supported in xvid_encraw) and CQ is fixed.

[holzi]

To Bad Multi Pass Bug still not fixed :(
Ok let's wait for another new version :)

[berrinam]

1-) When I do a AVI encode, the container selected in "Automatic Encoding" window is MP4 and not AVI.I think you are misunderstanding the meaning of the comboboxes. The filetype combo-box in the main window is unrelated to the one in the mux window.

And in the "Adaptative Mux Window" the Output selected is MKV, not AVI.Not sure what you mean. It is whatever you choose.

2-) When I don't encode the audio, I choose "Add additional content" in "Automatic Encoding" window. Then I choose my .MP4 or .MP3 file and click in "Go" button. Nothing happens. Then I change the file name and press "Go" button again to function correctly.I confirm this, and you can expect a fix soon.

[acrespo]

I think you are misunderstanding the meaning of the comboboxes. The filetype combo-box in the main window is unrelated to the one in the mux window.

Not sure what you mean. It is whatever you choose.


In latest stable version, when I choose AVI container in main screen and press autoencode, all combo boxes was set to AVI (in Auto Encoding window and in Mux window too) it's not occuring now, in Auto Encoding window the MP4 container is always pre selected and in Mux window MKV is pre selected (the container combo box fill only after choose the audio file and I choose MP3. the options in combo is MKV and AVI but MKV is pre selected).

2.5.7 doesn't work with mencoder due to mencoder being broken. something about planar alignments (I forgot exactly what the problem was).

xvid_encraw should function correctly for all versions of avisynth currently in use. what problems are you having that you think it's broken?
I receive a error from xvid_encraw when I do any encode when the source is a AVS script. It can't detect de video fps (fps = 0.00000000000) and exit after the error. I already post the error here. I don't know if it's related with the avisynth version, I only inform the version instaled here.

[berrinam]

It's no more work for you, and it means there needn't be an internal conversion between filetypes, because they are stored differently on the main form from on the other windows.

Ok, for me it's not a problem. I can select AVI again, but when people that use the stable version today will upgrade to latest version will guess that it's a bug, because tha stable version assume the main form settings in auto encode.

[berrinam]

@acrespo: I see your point, but I think they will just have to deal with it, like you do. :D

Now I think in 2169 I've fixed all reported bugs except:
15 One Click Encodes in a row causes Source Detection crashes
xvid_encraw AviSynth bugs, which I don't think are to do with MeGUI

Is there anything I've missed?

[unskinnyboy]

Ah, I think I managed to crash MeGUI. :D

Build is 0.2.3.2146 from ChronoCross. OS is Win XP 5.1.2600 SP2 Build 2600.

What I did:

Tools -> AviSynth script generator -> Options -> Video Input.

I selected a VOB file instead of a .d2v file and poof! MeGUI crashed (Don't ask me why I did it).

http://img98.imageshack.us/img98/5899/meguierror0ly.png

Ideally, you should throw a dialog asking the user to select the .d2v and not the .vob.

Reproducable error. No logfile produced. Let me know if you need to see the dump which Windows produced. I hope this wasn't reported before - I did a small search in this thread but didn't see it.

[ChronoCross]

you should try updating to a later version and see if it stil occurs.

the latest version of megui is 2169.

[unskinnyboy]

Where is 2169? Before I submitted this report, I saw berrinam saying "Now I think in 2169 I've fixed all reported bugs except", so I checked for 2169 in your site, but it wasn't there. If I had gotten it, I would have definitely tried with it too.

Your site is down btw.

[Adub]

Is it just me or does the Deinterlace analysis do one pass, show the correct/needed information with the recommended settings, and then keeps doing multiple passes for no reason?

I've removed all builds as there is no reason to have them anymore. the auto updater does everything that's needed. Hence why the page doesn't load lol. I'll post an auto updater build on my site now so people can start there.

It does 2 passes and then stops. I'm not sure the reason for the second pass but I assumed it had to do with error checking to make sure the first pass's results were accurate.

OK, I am on 2169 now (the autoupdater is lovely), but the bug I reported is still there, which isn't surprising if it wasn't reported by anyone else before and subsequently fixed. What I'd like for someone to do is to check to see if they get the issue too, just to ensure it isn't mine alone.

[Adub]

Right. Okay, thanks ChronoCross.

It doesn't crash on my system. Megui throws an error that says

"Directshowsource: The filter graph manager won't talk to me"

Perhaps you have a Directshow vob decoder that's crashing avisynth and thus megui. Or it could be the vob itself. Does it happen with other vobs?

[berrinam]

Is it just me or does the Deinterlace analysis do one pass, show the correct/needed information with the recommended settings, and then keeps doing multiple passes for no reason?The second pass is used to find the field order. Since it's only required in some places and it uses a different script, it is done in a different pass, but only when the field order is needed (interlaced/film/hybrid sources)

You are right. It was my MPEG-2 decoder after all. I had installed Darim DVMPEG the other day and looks like it took over MPEG-2 decoding without permission. :rolleyes: I have uninstalled Darim and now Nero's video decoder took over. But I must admit I am still not satisfied with the state of affairs, because now I am getting a script error: there is no function named "DirectShowSource" as if AviSynth itself is not installed. Instead of even letting AviSynth into the picture (and I am sure if I remove Nero from the chain, the error will be something else), can't we simply throw a dialog to the user based on the file extension itself? "Not a .d2v file" or something like that?

well one of the things that people had been clamoring for in the avisynth script creator was to be able to put whatever file they wantd in there.

.d2v is handled by Mpeg2source
.avi is handled by AVISOURCE
everything else is handled by Directshow source.

It's a give in take in this instance. I do however in all instances thing that .vob should be handled exclusively by DGindex. However IDK if it's possible for megui to have both the d2v creation screen and avisynth script creator open at the same time.

[unskinnyboy]

Well then, things don't look very peachy here. d2v opens alright, but avi, avs all give "there is no function named "DirectShowSource"" error. :-|

As for your question about the 2 windows, if I open an MPEG-1 file in AviSynth script generator, DGIndex Project Creator window pops up, and so yes, they can co-exist, but with DGIndex Project Creator as a modal window.

[ChronoCross]

do you have AVISYNTH installed? it seems wierd that it would continue throwing that message.

[berrinam]

It sounds like you do have AviSynth, but it sounds like you are missing the DirectShowSource plugin and/or the registry location for the AviSynth plugins folder is wrong. Check that the AviSynth plugins folder which MeGUI tells you in the settings contains DirectShowSource. Also, try reinstalling AviSynth

[holzi]

When I want to mux an xvid/avi file with AC3 Audio I get stucked. When I load the avi I can choose avi as the Container Format. But as soon as I add the AC3 Audio file I can only choose MKV. Which doesn't work for me :)

Or should I use the Divx Avi Muxxer?
This one dosn't work for me either because it changes the fourCC to dv50.

Greetings Holzi

[berrinam]

In that case, no muxer can be found. It's simply not supported unless you want to use a dv50 fourCC, so either make do with that or consider another container, like mkv, for instance.

[holzi]

well Ok then I just go with avi mux gui or virtual dub mod.
Thx anyway

My bad, yes. DSS was missing. I had moved all the plugins from the plugin folder couple of days back because of some DLL conflicts. I also falsely assumed autoupdater took care of it. Again, my bad. Had I checked the autoupdater window, I would have seen that DSS isn't one amongst them because it comes installed with AviSynth.

I have a related question which I will post in the feature request thread.

[Cantello]

While trying to generate an AVS script wiht MeGUI, it gives the following error message but does not crash.

Programs used: MeGUI 0.2.3.2116, AviSynth 2.56a.

The file I was trying to generate an avs script for is a standard xvid avi file with AC3 sound, which I encoded before from a DVD, which worked well.

http://img119.imageshack.us/img119/7206/clipboard014pn.th.png (http://img119.imageshack.us/my.php?image=clipboard014pn.png)

Could I be missing something? Reinstalling AviSynth did not help, even different versions (2.55).

Thanks for any hints!

[HieiYYH]

i have a xvid raw 23.976fps, i tried to encode in twopass to h264 raw (*.264) in normal profile, i only changed the Subpixel refinament to mode 7 rdo level 2 (slower), all the 2 passes are done with no warnings or errors, but there is a error, some random ones, look at the picture... i encoded a 28:40 video to 60mb, maybe the bitrate (250kbps) is too low for avc and so give this crap error or maybe a error in the avysynth script? i tried encode 4 times, and always give those erros :/ any help

http://xs302.xs.to/xs302/06240/videoerror.jpg

my script:
AVISource("video.avi", audio=false)
LoadPlugin("VSFilter.dll")
textsub("encode.ass")

[check]

Does the error exist in the avs file when you play it back in a media player? If so, check the original avi is ok and try without the subtitles to see if vsfilter is broken.

raw doesn't have any error, i checked already, the subititle that i used has only 1 line, for credits, can be the vsfilter?

ps: i'm using the latest version of megui and x264 codec CLI

Is the error on the same frame every time? If not and you're getting random, unrepeatable corruption, try this, as you may be pushing your system too near its limits. If so, it might be a bug in x264 and you should go back a couple versions.

You should also check that your command line doesn't contain anything related to aq, which are of unknown stability. (And no, turbo's fine if you're just going to drop the first pass.)

i don't think is my pc, i used to encode with x264 in virtualdub with 8fps average in mode 7 (rdo) without any errors, in megui the encode goes about 10-12, and i'm using LOW priority (maybe this?)

ps: tried to encode again in profile HQ-Insane, 3passes, the video errors are there again on 2nd and 3rdpasses (and it is random) :/ i think i'll go back to vdub -_- (No there's no AQ in command line) go back some versions? which version i should get?

even with the errors, i tried mux the video in yamb, i don't know why, the video has the same fps, same time, but the audio is playing too late (or the video is too fast) i don't understand -_-

Symptoms for hardware problems include:
- random reboots, system crahes often
- programs freeze, do not respond to user actions
- certain programs freezing during heavy use (e.g. when encoding)

i don't have those problems, the encode goes very well, and i can even play some emus :P


ps: the raw was a 120fps wmv9 one, so i reconverted to xvid 23.976fps, dunno if can be this too

Have you tried multiple players, because I've had similar problems with VERY old versions of libavcodec.

[Morte66]

Bug report for 0.2.3.2170 AviSynth script generator. Examples are in the attachments. The story...

Create a AVS profile (e.g. Deinterlace No-Denoise.zip) that uses "Clever Anamorphic Encoding" with the Encode "non-mod 16" option. Close the "AviSynth script generator".

Open the "AviSynth script generator" again, and open a D2V file, like in AvsGen1.jpg.

Switch to the "Edit" tab, like AvsGen2.jpg, and you'll see # Set DAR in encoder to -1 : -1. The following line is for automatic signalling
global MeGUI_darx = -1
global MeGUI_dary = -1...which is not the right DAR.

Switch back to the "Options" tab, change your clever anamorphic option to "Resize to mod16" and back to the "Encode non-mod16" you started with. Switch over to the "Edit" tab, like AvsGen3.jpg, and you'll see that the script now says:
# Set DAR in encoder to 175 : 96. The following line is for automatic signalling
global MeGUI_darx = 175
global MeGUI_dary = 96...which is just what we need.

So it seems that the code to plant the aspect ratio in the script is not triggered all the times it should be.

It doesn't seem specific to non-mod16, I got the same problem when I created a profile that started with the option set to "Overcrop to achieve mod16", I still had to fiddle the option to get the DAR to propagate into the "Edit" tab.

[acrespo]

Thanks berrinam. Now I can press "Go" button in adaptative mux window.
I still have problem with mux AVI files. Both Autoencode or manual mux (Divx Mux window) can't mux avi files correctly. When I open the final video in virtualdub I receive this message:
Error decompressing video frame 0: An unknown error occurred (may be corrupt data). (error code -100).
If I open in Media Player Classic, it shows a gray screen.
The file size is 5 Mbytes less than a video muxed in virtualdub.

I don't have access to a binary of 0.2.3.2170. Is it available somewhere?

Or does anyone know about other methods to diagnose DirectShow problems and how to solve them?

edit: Nevermind, I found it. Will try with 0.2.3.2170 tonight and report my experiences.
