MeGUI development

[Sharktooth]

i cant.

[Doom9]

why would you want to do that anyway? It's nice to know how big your video will finally be like, no?

[Sharktooth]

However, i fixed the style thing for .NET 2.0 only. with 1.1 styles are partially applied (only on tabs and menus).
any ideas?

.NET2.0 with styles:

... looks much better

Well, it's good to know what your actual encoded size will be, but I often zoom the video up to tweak filter settings and deinterlace thresholds before encoding. I know you're obviously seeing the same thing, but it helps when working on a relatively small laptop screen.

@sharktooth: All I know is that there are quite a few .Forms Control properties that are only available in .NET 2.0, like UseVisualBackColor.

Quick bug report using 0.2.3.1018

In the AVS Creator, upon clicking the IVTC option, the creator adds this line.

Telecide(guide=1).Decimate()

In actuallity, it should add this line.

Telecide(order=1,guide=1).Decimate()

FYI

[Doom9]

Telecide(order=1,guide=1).Decimate():

The order thing rings a bell but that doesn't appear to be mandatory as I just used IVTC in MeGUI yesterday and it worked out just fine.

[foxyshadis]

Order is TFF/BFF and if it's not given it'll use whatever avisynth thinks it is, which mpeg2source will set correctly. So always using order=1 could actually get you into trouble with BFF sources.

Upgrade your Decomb filter to the latest version 5.2.2 from Donald Graft's site.
It no longer uses the order parameter.

[BTW, this is mentioned in the changelog, and I'll be ading some code to extract the correct TFF/BFF decision from the d2v.]

@Doom9
Does You look @ internal class Encoder @ BeHappy source? Does You still need more? I believe - 30 minutes is enought to make it MeGUI.Encoder descendant

[Sharktooth]

Dimzon: please do not push ppl doing something. everyone have it's own business and maybe he had no time to check it.

[Doom9]

@Dimzon: unfortunately I'm both swamped at work, and at home. A codec comparison takes a great deal of time, especially if you have a considerable list of potential codecs that you need to put through a qualification phase. This year's comparison effectively started last week and there is little chance I get to write any line of MeGUI code until the end of the year. But here's one:

In Calculator.cs, find the method codec_CheckedChanged and add updateBitrateSize(); so that the bitrate gets updated when switching between XviD and other codecs (XviD considers bitrate = raw bitstream bitrate, for all other codecs bitrate = final size / length).

And here's how I think the tri-state thing should finally look like (mind you the method may be incomplete and was never tested)

		private void x264TriStateAdjustment(x264Settings xs)
		{
			if (xs.EncodingMode != 2 || xs.EncodingMode != 5)
				xs.Turbo = false;
			if (xs.Turbo)
			{
				xs.NbRefFrames = 1;
				xs.SubPelRefinement = 0;
				xs.METype = 0; // diamond search
				xs.I4x4mv = false;
				xs.P4x4mv = false;
				xs.I8x8mv = false;
				xs.P8x8mv = false;
				xs.B8x8mv = false;
				xs.AdaptiveDCT = false;
				xs.MixedRefs = false;
				xs.BRDO = false;
				xs.Trellis = false;
			}
			if (!(xs.EncodingMode == 1 && xs.Profile == 2)) // lossless requires CQ mode 
				xs.Lossless = false;
			else
				xs.BitrateQuantizer = 0;
			if (xs.NbRefFrames <= 1) // mixed references require at least two reference frames
				xs.MixedRefs = false;
			if (xs.NbBframes < 2) // pyramid requires at least two b-frames
				xs.BFramePyramid = false;
			if (xs.NbBframes == 0)
				xs.AdaptiveBFrames = false;
			if (!xs.Cabac) // trellis requires CABAC
				xs.Trellis = 0;
			if (xs.NbBframes == 0)
				xs.WeightedBPrediction = false;
			if (xs.NbBframes == 0 || xs.SubPelRefinement < 5) // BRDO requires RDO and b-frames
				xs.BRDO = false;
			if (!xs.P8x8mv) // p8x8 requires p4x4
				xs.P4x4mv; 
		}

The same method could be used in x264ConfigurationDialog.cs where instead of using x264Settings you access the GUI elements. This allows grouping of all related code in a single method that can be called in showCommandLine. Then GUI element events basically just call showCommandLine

MeGUI 0.2.3.1019

Changelog:
0.3.2.1019 6 Dec 2005
Changes by doom9 to make show progress window context sensitive.
Added resizing to the video preview window.

(The resizing is not really as pretty as I'd have liked, but after trying several approaches I think it's impossible to get a smoother result without moving up to .NET 2.0 which has some important improvements in how it handles these events.)

Changed Files
.NET 1.1 bins

This patch doesn't include the changes doom9 suggested above. I'll have to add those next time.

[Sharktooth]

... MeGUI-src.ChngdFls_0.3.2.1019.rar .... 0.2.3.1019...

[charleski]

lol, I did it again.
Ok, changed my templates so i won't keep doing that

[Sharktooth]

merged sources and bins are a the usual place though.
however maybe it's time to switch to .NET 2.0?

[berrinam]

As a general note for coding: in MeGUI, you should use MeGUI.GetDirectoryName as opposed to Path.GetDirectoryName, as (at least in .NET 1.1) you Path.GetDirectoryName will have no trailing slashes, except if the passed parameter is a root directory. This means that generating a filename using this could have two consecutive slashes if the filename is a root directory.

MeGUI.GetDirectoryName (a static function) is simply a wrapper for this function, which removes the trailing slash if it exists.

Also, there's a problem with running a One Click encode. The process will be interrupted, because of a MessageBox that pops up. Removing

            MessageBox.Show(Environment.GetEnvironmentVariable("PATH"), "Path", MessageBoxButtons.OK);

from JobUtil.openVideo should solve that.

[Sharktooth]

new bins and merged sources are up @ http://files.x264.nl/Sharktooth/?dir=./megui

edit: adding

Application.EnableVisualStyles();

in Main() will partially enable the visual styles on .NET 1.1 and enable all the style effects for .NET 2.0.

Ah that must be it. Sorry for the inconvenience.

Fixed, I think the bug appeared when I put in doom9's progress window changes before one of the variables was assigned.

0.2.3.1020 6 Dec 2005
Altered Path.GetDirectoryName to MeGUI.GetDirectoryName
Removed a redundant piece of debugging code from jobUtil.openvideo
Fixed a bug caused by incorporating the progress window code in the wrong place
[Should add this to the changelog: I also tried putting Application.EnableVisualStyles() in as Sharktooth suggested. It actually makes things look worse for me, but I have a custom theme applied to Windows. Anyway, see what you think.]
