in ffdshow vfw when u select H.264 , it says mode "One pass - constant bitrate " , is it really CBR or VBR ?

im still using clsid icl10 build.

Fixed in rev. 1650.

VirtualDub was passing me an RGB image with a negative pitch (i.e. the image was stored vertically flipped in memory) and my code then happily allocated a negative amount of memory for the buffers - guess I never tested that case...

Anyway, it'll work now, but buffering ahead in VDub will introduce a delay in the video since it'll return an empty frame until all buffers are filled, and of course the same amount of frames will be missing at the end. But, once again, there's nothing I can do about that...

np: Bola - W.i.K (Soup)

Not all DVDs have closed captions.

Most commonly known as ABR, but it's a form of VBR, yes. Renamed to average bitrate in svn.

@haruhiko_yamagata: RealAAC decoder and the LFE Crossover filter is not working together in r1625 , libfaad2 is OK. (Older version is OK, eg: r1523 .)

Tried with Nero AAC LC 5.1 in an mkv container.

Btw: what is the difference between the 2 (libfaad2 and reelaac) ?
The latter sounds better to me ... Am I right ?

Thanks

clsid · 29th November 2007, 13:08

They are two different decoding libraries. Afaik, libfaad2 is the best one of the two.

I can't reproduce. What does "is not working" mean? No sound at all or no sound from sub woofer or ...

I've just tried to test ffdshow_prebeta4_rev1656_20071029_clsid.exe on Windows 98, but unfortunately my old PC seems to be broken.
Any volunteers, would you test it on Win9x?

I told you: i have two dvds with closed captions (I know for sure) but they're not displayed by ffdshow.

St Devious · 29th November 2007, 17:17

is it possible to automate 2-pass encoding in ffdshow vfw with xvid and H.264 codecs , or does it have to be done manually ( first running the first pass , then the second ) ?

I'm in the process of installing 98SE on my desktop computer. I should have a response by the end of the weekend, if not, next weekend.

Thanks for the quick feedback: so I have found the bug.

It's only present with 5.1 ch AAC source:
- when you use realaac the output channel config is 7 ch instead of 6 !!!!!! (see at the Info & CPU section)
- I'm getting destortion sound because AC3 filter (v1.46) is connetced at the end of the chain to ffdshow, and -as it seems- it doesn't like "7 ch - LFE crossovered" input !

And -as always- thanks again for investigating/fixing the problem ...

Thanks. Strange, for me realaac is sounding better ...

You can count me in.
I have one machine running win98.
Just PM me or do whatever you like...

Thank you very much!
Just opening one file using ffdshow would help much.
Further important testing may be ...

subtitles (ANSI and Unicode input)
Launching VFW configuration dialog
Launching makeAVIS.exe
preset loading

Of course, if you are interested in these features.

Oh, yes. I saw the letters "7ch". I should have found it. Thank you.

[*]subtitles (ANSI and Unicode input) not tested, no file available at this time.
[*]Launching VFW configuration dialog | ok
[*]Launching makeAVIS.exe | ok
[*]preset loading | ok

Pretty much I tested on the fly seems stable.
Subtitles in ANSI works on former releases.

I'm New In Here .. May I Ask A Question : Is The Ffdshow H264 Encoder Updated To The Latest x264 Edition, I Mean, On Which x264 Library Build Is It Based ?

I Have Noticed Also That When Decoding With Ffdshow, The Decoder Usualy Fails In Autodetecting The ColorSpace I'm Using .. This Occurs Frequently With RGB32 Encoded Files, He's Decoding Them As If They Were In YV12 Color Space, Is It A Bug Or Is This Normal ?

By The Way, In Case The Above Question Has Been Asked Before Please Forgive Me, I'm Just A Newbie.

Thank you very much.
This sample would help testing subtitles. It has UTF-8 SSA subtitles, which may be a bit difficult task for Win98.

What kind of file is the RGB32 encoded one? Is it H.264?
