2nd pass filesize set to 5,000kB
results:
avi = 5,014kB
ogg = 5,042kB

2nd pass filesize set to 2,000kB
results:
avi = 2,154kB
ogg = 2,161kB

Seems to be working ok to me.

For me:

2nd pass filesize set to 8,192kB
results:
8,164

2nd pass filesize set to 12,288kB
results:
9,116

2nd pass filesize set to 10,240kB
results:
9,116

2nd pass filesize set to 20,480kB
results:
9,116

2nd pass filesize set to 5,120kB
results:
5,136

I tried many different filesizes! It seems that if you set a filesize that ffdshow thinks is much more than needed, then it cut it down to what it believes that is better, but the quality of video is always bad!!!!

Do you understand the meaning of "saturation"? 9,116 KB seems to be the size for a constant lowest-possible quantization, therefore maximum quality possible. So, try to compare with CQ more if the results are similar -- if not, then it may indeed be wrong.

Would be nice.

And, BTW: Please, don't misunderstand me - sometimes I sound a bit demanding, but just accidently, I'm not a native english speaker...

Hey, I am not a native english speaker either!!!
I didn't misunderstood you!

Ok, let's see!!!

Source
Source

--------------------------------------
Filesize Set to 20,480
Actual filesize 20,496
encode1

--------------------------------------
Filesize Set to 25,600
Actual filesize 23,368
encode2

--------------------------------------
Filesize Set to 30,720
Actual filesize 23,368
encode3

Yes, the last two results (which have the same exact actual filesize) are similar! It seems that we have the maximum quality possible!
Then the only thing I've got to say is that I am really dissapointed from the quality!
The first time I saw all this detail to go away, I thought that I've done something wrong!!!!

That loss might be what it looks at max quality or whatnot...you still don't want to saturate the codec. Try using some filters to fix it up instead.

I wanted to see how good can this codec compress a video! Using filters to saturate more, is not an option for me! I don't like to put filters in my dvd backups for any reason! I really prefer to wait a year or two of development and see the codec to encode better and to keep more detail on its own!! I know, it might sound strange what I am saying, but that's me!!!

I tried to make some videos with ffmpeg2theora 0.15 with (--videoquality 10) and the video quality I got was really great! I think now that there must be something wrong with ffdshow. Maybe in the 2-pass mode it provides! Ffdshow doesn't keep any quality, even at highest filesize I set to it. Ffmpeg2theora gave me great results!!!

celtic_druid's 20050920 is out.

I got 500GB/mo bw for this mirror, but (it's a darn cheap server and) might be slower.
http://ffdshow.faireal.net/

This server might be faster, tho the bw is more limited here:

I just compiled a ffd yesterday for the CCCP, waiting on test reports on that one to see how it turned out. And I can provide a 300GB/mo, avg. 500kb/s mirror if you really want one.

You can mirror the files.
That is your right, not your duty.
Those are free software.

I wouldn't haste too much to upgrade to a newer build (0920).

http://sourceforge.net/tracker/index...61&atid=471489

I experienced problems with h264 playback, and according to log, several fixes were applied to that part of the ffdshow, as i recall. Maybe it's only due to some optimisations not working or so (athlon xp cpu). But 0920 does play same video fragment encoded in avc noticable slower than 0909 does (or at least on my system it did), so I rolled back to 0909 atm.

Well for 0920 I am testing icl/gcc for libavcodec. As a rule I just use gcc. If it turns out to be slower I will simply switch back.

Here are some alternative compilations:

Comments on stability and speed are very welcome. Don't forget to mention your cpu brand, type and clockspeed.

Mirrors aren't really a problem.
I got plenty on x264.nl

ffdshow-20050920.exe is a big file again, i assume its ICL?
Can you compile a MSVC71.exe version again too?
I really prefer stability over speed.


Creating x264 revision 295 test files now (.avi/.mp4/.mkv/.264)

In the past week or two, bug reports have come floating in about module violations in ffdshow.ax, which have been fixed by going to the libavcodec.dll full, not the libavcodec_dec.dll. As of 9/18 or so, it still seems to borkened. Not too big of a deal really, except adding 500kb of filesize + the encoders.

clsid: How can I download the RAR file from that page? Nothing happens for me. I'm on Firefox and JavaScript is enabled (but Flash is disabled).

bob0r: My problem is huge sites such as betanews.com direct-link to my poor pages, hogging the servers' resources. They should link to powerful servers like yours. I got a cheap virtual dedicated server for this but it's not powerful enough. Maybe I should get a real dedicated server. big ouch money-wise...

I just pressed the press here to download button and it worked. Had to wait ~45secs first though.
