ffdshow development

[oddball]

Any news on progress of this? It seems to have been a long time since there was any news on the devlopment of this filter. Things like playback of DiVX5.03 content (Mentioned by me in an earlier thread) and a working libmpeg2 implementation appear to have been put on hold. Also noted the test version of ffdshow that appears to crash for everybody.

Any news?

[athos]

i havent heard from milan for several months.

latest cvs commit for ffdshow was 2003-02-18 17:00 and for ffvfw 2003-02-11 06:41, i just checked both.

[Chibi Jasmin]

Can you get a working binary out of the latest ffdshow?

[athos]

well, i havent been able to, but if anyone succeeds, please let me know how.

[kilg0r3]

Isn't there any way to contact milan. I do not mean to press him to work on the filter. It would just be nice to know, whether everything is allright. It always feels strange when people disappear from the net just like that.

In any case, if ffdshow were not developed any further, it would be also nice to know which playback filter will realize the simple idct, that is necessary for proper playback of xvid files.

[Sirber]

Milan can be contacted here:

cutka(a)szm.sk

[kilg0r3]

Who will? I don't think that there is any point in flooding him with mail.

[Gazza]

Does anyone know if ffdshow development is still alive & well?

[milan]

I'm not working much on ffdshow currently. There are two development branches now: one for experiments (currently almost completely broken) and one "stable" where I'd like to make just bugfixes and then release it. However I'm now working mostly on ffvfw.

[kilg0r3]

hi milan, glad to hear all's well.

For ffdshow, imo, the most important thing is to make sure simple idct works so as to correctly decode xvid qpel. i understood that the qpel smearing, was due to some bug or incompatibility in this area. so, it would be really great of you, if you could have a look at this.

Thank you very much!

[milan]

Well, I'm not sure what could I do with that. It's related to libavcodec and XviD libraries and I'm not developer of any of them. But be sure I'll try to do something. The fact is I'm not using qpel for encoding yet, so I wasn't aware of this problem.

[oddball]

What about MPEG decoding? That is still broken. Would be nice if that worked. Also DiVX5.03 has issues with smudging. Probably a similar issue to the Xvid one.

Still..

It's actually very simple: please please pretty please, just make a working build with newest libavcodec

There were two problems 'working' together: one was a bug in libavcodec (mpeg4 standard got changed to be constent with.. reference software, yet libavcodec was not aware of the change) and there was a different problem on xvid side - our idct's imprecision was somehow amplified by quarterpel filter.
We are currently switching to 'simple' idct (can be easly selected form current ffdshow config). Libavcodec had its bug corrected somewhere in the middle of January (if I remember correctly).
All we need is this new libavcodec

Thanks,
Radek

@oddball
I'll try.

@sysKin
Ok, this weekend I'll spend stabilizing ffdshow and next week there will be new alpha build. Not yet stable release, problems similar to that pointed by oddball should be fixed first.

[kilg0r3]

Thank you very much. All the best to you

[Gazza]

Hi Milan, good to hear from you again. Good also to hear that another update to ffdshow can be expected at some time in the future.

Considering that you are more involved with ffvfw at this time, I will have to also divert some time to see what it is all about.

Milan,
I just want to thank you for your great work on ffdshow.
This is now an indispensable tool for HTPC's.
I have been using the Resize filter (Bicubic) with Luma & Croma Sharpening and find the results to be outstandingly good.
I started a topic in AVSForum on this.

http://www.avsforum.com/avs-vb/showt...hreadid=234832

I thing Resize and Sharpen had been overlooked until I started this thread. But now people are on to it and are very happy with the improvement in quality it provides.
Is there anything that can be done to improve performance with the Resize/ Sharpen filter and the Gradual denoise filter.
This combination of filters is hard to get running without stuttering.
Thanks again, and I hope the see future releases of ffdshow soon.

Regards,

Owen

Finally, I managed to make a working build of ffdshow. It seems I had managed to screw up DirectX 9 SDK :\

Anyway, ffdshow-20030418.exe was built from a fresh checkout of the CVS tree, V1 branch, which is supposed to be stable. Did some quick testing only.

Take note: the property page (config) will crash unless you have ffvfw installed. I think this is due to milan working on integrating these two projects (either that or i screwed something else up ;)). For this reason I will not put up this build on sourceforge.

You can download this build of ffdshow, as well as my latest build of ffvfw from http://athos.web1000.com/ffvfw.html. I am aware that some people are having trouble downloading from this site, so please feel free to help me out by mirroring this file. I will put up a build at sf.net when the ffvfw issue has been resolved.

Also note that sh0dan has compiled later builds of ffvfw, located at http://cultact-server.novi.dk/kpo/avisynth/avs_cvs.html and nitrogen has mirrors at http://homepages.pathfinder.gr/ffvfw and http://nitrogen.kicks-ass.net/ffvfw/. I only tested with my ffvfw-20030325 build, dont know what other ones work.

@athos: the link either goes to a web1000 search site and one in 5 times I tried I ended up on a swedish site.

[mwillberg]

if you remove the last "." from the link it seems to work ok...
