sx264 - qt based x264 gui (Linux&Windows)

[Selur]

@Dark Shikari: one of the comments I got this from was:

Don't use p4x4 partitions with level >= 3. (This is one of the constraints x264 doesn't warn about.) (Strictly speaking p4x4 is allowed in the standard, but there's some restrictions on where it can be used, and x264 doesn't check those restrictions, so the only way to be sure is to disable p4x4.)

see: http://forum.doom9.org/showpost.php?...77&postcount=5
don't remember where I got the other part from, but if you say p4x4 will cause no problem at all, I'll happily remove the restriction.

Theoretically, he is right.

In practice, not even the reference encoder abides by that rule. It is meaningless, and, quite literally, nobody cares.

[Selur]

Okay, just wanted to make sure that it wouldn't cause any incompatibilities.
-> I'll lift the restriction.

Update:
*changed*
- allowing p4x4 at all levels
see: http://forum.doom9.org/showthread.php?p=1222781 and following; in short: it's not standard conform, but nobody cares

-> updated 1st post

[Sharktooth]

megui still enforces the standard.

[Selur]

-> started a small poll to see what the community prefers, see: http://forum.doom9.org/showthread.php?t=143419
isn't much of a change to me anyway, so I'll go with the community there

@ Selur

Why fight about/discuss p4x4 so much? If my memory serves me correctly, pengvado (akupenguin here on doom9) once said that out of all partitions, p4x4 is the one that gives the least compression and basically has little to no benefit at all on a lot of content. Do you really think you will see noticeable effects both in compression and quality if you turn on p4x4 or disable it? My guess is you won't

[Selur]

The question is not if it helps with compression, it's whether one should care about standard conformity.
Since (I think) most people assume when they select a specific profile@level in a gui the output will meet the restrictions of this selection, I think it's a good idea to ask what people want if you don't deliver what they suspect.

you want standard conformity? then go find another encoder as x264 won't deliver full standard conformity no matter how much you tweak its options. It may come (very?) close to the standard but full conformity is out of the question at the moment. As Dark said, you will probably have to stop using cabac and probably a few other things

I was being pedantic in pointing out every last little thing that could theoretically violate the spec.

I doubt any other encoders care about such things either.

[Selur]

I prefer to stay close to standard, and not break it if I must not. I also like x264 and will use it further even when it might not be full standard conform. If you don't like that I see not how I could help.
I totally got Dark Shikaris point about p4x4 that if nobody cares about p4x4 restrictions it might be valid to use it. I just think it's a valid question to ask others that might want to use the gui I what they prefer. Seems like you don't care about any compatibility that's fine with me.

Hallo Selur,

thx for trying to help me.
But its not working. Your 64bit bin 413 crashing on my 64er Etch.
Seems to be there is a conflict with the libraries between kubuntu and Debian.

I have also tried to compile the rev.413 with the same error.

nwidget/NListWidget.cpp:8: error: ‘class NListWidget’ has no member named ‘removeItemWidget’

For now i have these line complemented out and the process was successful

How up to date is your qt version?

[Selur]

This might cause a problem with zone and chapter option, since this might stop sx264 from clearing the chapters and zones.
Checking QT Documentation: "This function was introduced in Qt 4.3."
-> I agree with Merlin7777, it might help of you update your qt version.
iirc qt 4.3 was released around june 2007, 4.4 was released around may 2008, I don't think that I used any options that were introduced with 4.4 but 4.3 seems to be mandatory to run sx264.

[JxPhoenix]

awesome program!! it gives you a very wide range of options to use, finally i was capable of converting videos in h.264 quality for my iPod.
Thanks a lot!

sx264 Test with - OpenSuse 11 - KDE4 works fine.

I have tried all analysers but none will seem to accept mp2 input. FFmpeg appears to analyse all data and then errors no audio input.

Actually I have now converted it to mp3 vbr192 with lame. and no analyser lets me select it as a audio track same error as above similar log. Interestingly and probably nothing to do with your program (but the external ones)they all guessed a bifferent bitrate.

@Henrik: You might want to adjust your dpi to your monitor, seems like the font size hints are off.
@flebber: found the problem there's a small copy&paste error, will fix it and upload a new version later.

Cu Selur

[Henrikx]

Yes. My monitor or Graphics card is broken.Synchronization is broken.
Fonts with max 70(?) dpi is possible. Next week I buy a new (Quad Core!!)
But the statement remains, sx264 works fine ...

[Selur]

rev415
*fixed*
- some minor bugs with seperate audio stream handling

*changed*
- limit p4x4 usage again on default

*added*
- option to allow p4x4 for all levels

*updated*
- Windows package: new mplayer, ffmpeg, mediainfo, x264

-> updated 1st post
