Selam! (XviD-1.0-Beta3-26122003)

[Koepi]

Merry Christmas everyone (...who celebrates it).

We have an christmas gift for you!

XviD-1.0-Beta3-26122003 (Selam):
- Large filesizes now work correctly in 2pass.
- Fixed possible out-of-bound-reads in 2pass.
- Bframe decoding fix - sometimes bframes were referencing wrong future macroblocks.
- Checking "use keyframe" in a zone now only makes the zone starting frame a keyframe.
- Internal pixel aspect ratio fixes - added display aspect ratio (for anamorphic encoding).
Currently you'll need mplayer, vlcplayer (or 3ivx/Nero DShow filters) for correct playback.
- Colour space fixes.
- Directshow updates: brightness slider, postprocessing, output colour space choosable.
- Some more sse2 optimization for P4s.
- 2pass ratecontrol overhauled, including fast first pass.
- User selectable turbo mode.

Known bugs (do not report them):
- Weight zones don't work properly - if you need zones, use quant zones instead.
...

Best regards
Koepi

Thanks a lot, Koepi and Merry Christmas!

[raz0r]

thanks koepi!
but what is "Turbo ;-)" and how does it work?

[mikeson]

@raz0r:

but what is "Turbo ;-)" and how does it work?

It is a feature that turns off some ME flags thus encoding is faster (roughly said).

[raz0r]

will the quality go down when using turbo mode?

[mikeson]

Test it and share your results...

Honestly, I'm not sure about this.

[Koepi]

Turbo should give a very marginal (unnoticable) drop in quality (it enables fast flags in the xvid core) for a very noticable speed boost.

Selam, dostum!

What a fantastic name for the new beta! This one should be especially for me! I might even no longer upgrade and use this one for good!

Thanks a lot,

The new decoder has performance problems when deblocking is activated. FPS drops on a XP2400+ tested with a 704x304 clip.

the brightness slider has no effect in any of the possible colorspaces.

Whoa - I was just going to write almost the same, only that this happens here on a P4 2,4GHz... so it can't be CPU optimization-specific.

The clip in this case was 720x400.

Dering alone does work without slowing the video down, as does "Film Effect" (even though I don't know what it's supposed to do... )

But then again, deblocking did work perfectly with Koepi's prerelease beta3 decoder, so a bug must have crept in there...

np: St. Germain - What's New? (Boulevard)

[Koepi]

Hm. The decoder is currently absolutely un-optimised, it doesn't compiler with any ICL anymore. Maybe i should tweak the settings for M$ compilers ...

Oh, again?
I had problems with deblocker the first time I compiled it (on ICL8.. and yes, it worked *then*).

When I used deblocker the second time it was perfect - slower than ffdshow's of course, but imho it was the best deblocker I've ever seen. It was just so beautiful ^_^.

I'll try figuring out what makes it go fast/slow/fast etc all the time.

PS. Deringer is fast because it's not implemented

Well, I don't really care much if encoding goes below 24 fps, but it *does* get a bit distracting when watching the result and having the video play half as fast as the sound... *wink* *wink* *nudge* *nudge*

And I really have to agree with Syskin - the deblocking of the prerelease beta3 decoder was superb.

(Also, wouldn't *not* using the Intel compiler slow down both Intel *and* AMD CPUs, given that the optimizer of the VS compiler is hardly worth anything?)

And to Syskin - I've only seen it go slow, without speeding up anywhere...

I have problems to download this beta3.

I use mozilla and explorer and no download manager, but i have always a message of error

[bond]

i saw packed bitstream is now default! why that?

[raz0r]

made to quick tests, one with and one without Turbo. It wasnt any faster at all and quality was also same, so i think its (now) useless.
oh and it now plays on ESS players, thats very fine

All "turbo" optins are related to b-frames and qpel. It won't make Simple Profile faster.
It won't make any differnce in first pass either.

[raz0r]

ah ok then its clear, cuz i didnt use bframes/qpel/gmc

<conspiracy theory>
Probably to make people use and test the new DirectShow decoder instead of ffdshow which can't play packed bitstream correctly...
</conspiracy theory>

Still, it's the first thing I turn off after a "Load defaults...".

[Koepi]

Ffdshow will be fixed soon I think. It's no xvid bug that ffdshow doesn't playback packed bitstream correctly. Head over to the ffdshow thread in new a/v formats(codecs) and file a request there
