MeGUI - x264/XviD/lavc/Snow encoder with MP4/MKV/AVI output & audio

[Sharktooth]

@Frank_UK: ill make a new build tonight.

@brogan: you need to install a directshow DTS decoder, like ac3filter.

[Frank_UK]

@Sharktooth - Thanks for build 0.3.0.3003; working correctly again now.

@kurtnoise13 - Thanks for fixing bug ID: 2152972; working correctly again now.

Probably a bug in XviD configuration dialog.
I was trying to use MeGUI 0.3.3004 to call xvid_encraw.exe for XviD encoding.
I manually added zone options in the "Custom Command Line" field under "Advanced" tab of "XviD configuration dialog" window (Input->Encoder Settings->"XviD: *scratchpad*"->Config)
I put in the custom command line field

-zones 0,w,1.0,0KOC

I got from the command line display field below

program -i "input" -single -bitrate 700 -smoother 0 -nopacked -closed_gop -threads 1  -o "output" -zones 0.w.1.0.0KOC

Notice that commas were automaticly replaced by dots.

Then, when trying to encode, xvid_encraw.exe complained:

xvid [error]: Zone error, bad parameters 0.w.1.0.KOC

Just a little bug I noticed. It may have been addressed before though...

When using the bitrate calculator in MeGUI and loading in a 1536Kbs DTS audio track, it was actually detected as 1510Kbs.

I overlooked this and did a 8 hour 1080p encode, only to realise at the end I was 8MB over a DVD-9! Doh!!

Done... I didn't realise that you could do this without being a member (ie: logged in).

I use x264: CE-Highprofile to encode my video. I find the quality to be superb.

I understand that this is now an obsolete profile, I have been advised to use x264: Unrestricted 2pass Balanced instead.

Is there any real advantage to move to the new profile? As I find the quality of the old profile superb.

[Sharktooth]

check by yourself.

Hi guys. This has been bothering me for a while, so I downloaded the meGUI source and implemented the feature on my own, and would like to contribute it to the program if you find it useful. What I did was add another field (not sure I like the GUI implementation, but it is easily changed) that shows the frames per second for more limited amount of time rather than overall. The problem I have with the current scheme is that once you get a couple hours into your encoding, any changes to the CPU usage aren't reflected in the frames per second display. I implemented it using a deque, which I had to import since it seems C# doesn't have such a structure, at least to my limited knowledge. The deque keeps track of the current frame rate and after a certain amount of time, 2 minutes for example, starts sliding and using the values to measure the FPS.

If you guys find this useful, let me know and I will submit my code for review. My only issue is how to represent it in the GUI, which I added another textbox for, which I am not convinced I like, but simply adding it to the current FPS reading might make that display look too cluttered.

Hi, i was going to convert a dvd to h264+aac .mkv, then when i was going to convert the audio with nero aac (multichannel 128 kbps) i get an error. I tried reinstalling and trying winamp aac and faac, but it gives the same result.
And in the log it says like this :

"An error occured"
"Stacktrace
at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath
at System.IO.FileStream.WriteCore(Byte[] buffer, Int32 offset, Int32 count
at System.IO.FileStream.Write(Byte[] array, Int32 offset, Int32 count
at MeGUI.AviSynthAudioEncoder.encode()
Inner exception: null
Output from encoder via stderr
Output from encoder via stdout: ERROR: Could not initialize SBR"

Thanks

P.s. Audio is from dvd, 3.1 ac3.

please post a patch in the megui patches tracker on sourceforge. it will be reviewed and implemented if it makes sense.

from the wiki:

Other optional programs that MeGUI can use:
Nero AAC Encoder: This is the free Nero Digital AAC encoder which can be downloaded from this Nero webpage. Extract neroAacEnc.exe and set the right path to it in Settings -> Program Paths -> Audio -> neroAacEnc

a similar procedure is needed for winamp encoder.

@SeeManRun: I guess it's a matter of definition when you say accurate. There are encoders that show the effective FPS measured over the last X frames or X seconds, and then there's megui which calculates FPS not on those terms but over the entire movie. In the end, if you want to compare FPS measurements, the latter is much more useful because localized FPS measurements can very greatly with the complexity of the source.

Oh, and C# has a Queue with Enqueue and Dequeue methods.

I suppose more accurate is not the right way to put it, but maybe more useful. I use a quad core CPU for my encoding, and when I need to use the computer for something else, its nice to know how much I am affecting the encode, which is why I created the patch. I'll check out the queue (I was a little surprised that there was none on my first check) and submit that patch as Sharktooth says.

When MeGUI is started x264 for the encoding, x264.exe simply crashes.
x264 core:65 r1016M dbc5ef0

Way to go !!!

So very helpful. Check the log file at least.

I already set the paths. And if i haven't, wouldn't it say that the file is missing? And it almost seems that only me has this problem.

[Kurtnoise]

are you sure that your audio file from DVD is 3.1 ???

maybe that's why the encoder fails...

Added the patch. I also looked at the queue class in C# and it doesn't support removing from both ends of the queue, which is why I brought in the deque class. Perhaps a little heavy duty for my use, but the compiler should strip out anything not used anyway
