sex264 (updated almost daily by now)

sysKin · 5th January 2005, 11:55

Hi everyone

I just finished "my" first really working build of x264 with up-to-date VfW interface. The GUI has most of the options that core has, including bframes, two-pass, and motion estimation selectors. It's pretty ugly I admit but I don't care

I need testers. Consider this version RC1 - I think it works but I don't feel like testing

The name is sysKin's experimantal x264, or sex264 for short.

Grab it (build and src) at http://syskin.is.dreaming.org/x264/ .

Have fun, and don't forget to report anything that is wrong or missing.

Radek

[edit 9th Jan] New version available.

sex264, nice name! lol

Sirber · 5th January 2005, 12:55

Cool!

What are the *working* features?

[edit]

Install don't work, VDub don't see it

Whatever x264's core currently has. Ffdshow doesn't want to play its b-frames (asserion error with newest Celtic Druid's build) but Videosoft's decoder plays them fine.

Very bad. This definitely works for me - check if x264vfw.dll got copied to windows\system32\ (ah, maybe you're not administrator?).

Sirber · 5th January 2005, 13:22

I'm administrtator. Second click on the .inf, install. It seems to copy a file but in VDubMod, nothing

[edit]

Tryed with regsrv32.exe, but it said function DLLRegisterServer is not found.

np showing up here in vdm

btw syskin you might want to consider using "avc1" as fourcc, its not nice looking, but still its the four letter "fourcc" the mpeg-4 standard defines to use for signalling h.264 in .mp4 (i think it can be taken as the equivalent to the .avi 4ccs)
its already supported by ffdshow

edit3: maybe it would be also nice to add a description to the subpixel options (eg uses qpel, uses hpel aso..)

edit: and how do you make 2pass working in vfw?
for the first pass i assume you use constant quant, what quant do you use?

edit2: two gui problems:
1) the "ok" button in the advanced tab is divided by the bottom line (i hope its clear what i mean)
2) i still get the problem, that when i push the "load defaults" that all values get set to 0 and all options get unticked in the advanced tab

great!cann't wait to try it.
Any mirror?i just can not visit that url.

Today's build by celtic_druid can play it back without any problems.

Just a question: what is the recommended b-frame prediction mode, temporal or spatial?

Shinobu · 5th January 2005, 14:29

no problem at all with this codec, but i'll launch more test this night ^^.

the load default isn't working great on windows 2000, you have to close the config tab of the codec and reopen it to apply the reset.

Hi sysKin,

Will an Mpeg4/AVC implementation, such as this, ever make it into XviD?

Side Note:
I wonder how quickly Doom9 will get round to creating an Mpeg4/AVC section. As the forum is full of such discussions

Cheers

virus · 5th January 2005, 15:32

Ok, I've already reported to Radek the most obvious cosmetic flaws, now I'd like someone testing for a more serious issue.

I run several 2pass encodes (settings: all @ default) from the same 1stpass statsfile, just changing the target bitrate. When aiming for medium or high bitrates, everything went fine. But when aiming for low bitrates (450 kbit/s) everything b0rked with an assertion in ratecontrol.c.

According to sysKin, that should happen when the statsfile is shorter than needed... but the statsfile is OK since I run several successful encodes with it. I observed that problem in the past with ffdshow though - at the times it seemed to happen when the 2nd pass average QP was much bigger than the 1st pass one (1stpass is run at fixed QP=26 currently, so you need to go with very low bitrates to trigger it in sysKin's build).

If you can try and see if that happens to you too, that would be great. Thanks!

Yesterday i have downloaded an installed 03012005_x264_bin.7z with the right-click-install method.
What is the recomendet procedure to update differen versions of sex264 /vfw codecs in one dll?
Just replace the x264vfw.dll?
regsrv32.exe -u x264vfw.dll and right-click-install the newer version?
And how to uninstall?
regsrv32.exe -u x264vfw.dll and deleting the dll?

Hellfred

bond · 5th January 2005, 15:53

maybe someone finds it interesting and so i dont forget about it:

when encoding with x264 vfw with b-frames (eg in virtualdub(mod) you will maybe find out the following (as i did):

- when choosing 2 b-frames -> two zero length frames get placed in the output stream (frames that avi thinks exist, but in fact dont exist

) -> as the output stream has the same framenumber as the input stream this means that practically there are 2 frames too few in the output
- for 1 b-frame -> 1 zero length frame -> 1 frame lost
- for 0 b-frames -> 0 zero length frames -> 0 frames lost
aso...

thats caused by the video for windows (vfw) framework (as used in vd(m)), which is NOT able to handle b-frames correctly on its own (as b-frames are a newer technology than vfw)

i talked about that with syskin and he meant that the old workaround to solve this (using one-byte 0x7f frames) should not be used, as it creates an incompatible stream if the app (eg everything, except vd(m)) doesnt know about it

Tommy Carrot · 5th January 2005, 16:01

@Hellfred: replacing should do it.

@Bond: that is exactly how the b-frame support works with xvid, if it didn't bother anyone for years, i don't see why it suddenly became a problem with x264.

because the workaround working for xvid, doesnt work for avc (in xvid no frames are lost)

you should read the whole post

Tommy Carrot · 5th January 2005, 16:08

Well, i'm sure syskin will find a simple solution for that.

bond · 5th January 2005, 16:16

he meant the best is to keep the current way (who cares about 2 frames in a 200000 frames movie

)

another way would be to make avery adopt vd to beaware of these lost frames...

anyways just wanted to post that info so it doesnt get lost in the depths of irc

JoeBG · 5th January 2005, 17:54

I really have no idea how to use it. I downloaded everything, but there is no *.exe. I always thought, a gui has a *.exe.

How does the tool work?

Sirber · 5th January 2005, 18:29

you're supposed ti install it using the .inf, but it failed for me

stephanV · 5th January 2005, 18:42

I have a small question.

Since i recently (today) found out about the difference between I-frames and IDR-frames, i was wondering: is the keyframe-interval really the keyframe interval? Or is it the I-frame interval? I suppose i could try and found out, but i'd rather have some confirmation about it.
