XVID Bug??? - Build 25.09.2002.2140

[jpl]

I think there is a memory allocation problem with builds Alpha.25.09.2002.2140 and newer of XVID from Umaniac's site. When I try to start an encode Virtual Dub just sits there for about a minute and then I get a error related to being out of memory and the swap file at maximum size. When I check the W2K task manager it is reporting over 650MB usage. I tried several different source files with V-Dub native and through AVISynth. I also tried to with default settings for 1-pass (CBR & const-quant) and 2-pass (1st pass). If I revert back to build Alpha.23.09.2002.0840 of XVID the encode proceeds as normal.

I was really hoping to check out the new ME improvements from SysKin

My system is a K6-3 with 384MB ram, 13.6 & 40 GB HDD, running W2K SP2, V-Dub 1.4.10 & AviSynth 2.05

I think it's because vfw is being compiled without BFRAMES defined in the project settings. When I added BFRAMES, it worked a treat.

Yep, I noticed the same thing. I went back to the old version. I'm testing out my new best hvsmatrix on "The Matrix." I'll post my results later.

Could someone, please, attach a compilation with bframes enabled? I want to test the new ME improvements from SysKin and I have the same problem with memory.

Nitrogen,

PM me your email address and I'll send you such an dev-api-3 build.
The credits stuff is somewhat broken as all 2pass stuff as sysKin's ME has a weird feature which dynamically decides on i/p/b frames - that's a second pass killer. But still, it's fine for testing (the reason that 2pass is somewhat broken is stopping me from releasing that binary).
You've to playback with ffdshow though when using bframes as the xvid.ax from Nic crashes there (didn't try if the vfw dll crashes, too - you might do that then ;) )

Regards,
Koepi

@Koepi

To enable Bframes all you have to do it to put #define BFRAMES to config.c??

Koepi,

Would be so kind as to send a PM to me with that build?

Thanks,

Dali

@Dali Lama:
Unfortunately PMs can have no attachments. Use the "standard procedure" described above.

@Moonwalker:
You need to put it in xvid.h so it is used by VfW as well ;) Additionally, you want to add a #define BFRAMES_DEC right below it ;)

Regards,
Koepi

If you enable B-frames do other people trying to play the file need a newer build of xvid?

[Teegedeck]

They'd need the latest build with a dshow-filter that decodes B-frames properly. But easier:

Just decode XviD with FFDSHOW!
Fantastic software, ffdshow, as Koepi mentioned in 'the other' thread...
