ffvfw

@ookzDVD

First of all, make sure that the encoded avi does playback properly in Vdub.

If it does you have a couple of choice:

Turn off FFV1 decoding in the ffdshow 2003-10-28. MPC should now use ffvfw 2003-09-27 for decoding (you will see AVI Decompressor (FFV1) under filter).

Or, copy the libavcodec.dll and libmplayer.dll file from your ffvfw 2003-09-27 folder and drop it into the ffdshow 2003-10-28 folder.

Finally, the best solution, uninstall ffdshow 2003-10-28 and install ffdshow 2003-09-27

I downloaded the ffdshow 2003-10-28 and also got the green screen. It seems that libavcodec support for FFV1 is broken in both ffvfw and ffdshow 2003-10-28 builds.

BTW, I still use ffdshow 2003-04-24... All the latest ffdshow either crash or freeze when playing Packeted Frames DivX50 avi with Chroma Dering postprocessing on.

As for ffvfw setting, the default work fine for me:

YV12
VLC
0
250

@winman,

Thank you for the update,
I did try encode use the build 2003-09-27 and disable the ffdshow
for ffv1, and everything is working now.

@CruNcher
What is your decoder anyway ?


PS. Wanna try with 2003-11-13 build again.

Thanks.

heya

i think i am blind
ffmpeg offers two error resilience methods: data partitioning and resync markers
i only find the data part option in ffvfw, but not the resync markers (called "error resilience" in the ffmpeg docs)!

would be great if this option could be implemented in ffvfw too

edit: and doesnt ffmpeg support outputting real .mp4 streams (i mean no avi hacks aso)?
if yes, would be great if that could be possible in ffvfw too

if I may interject. Is there a way to use the standard ffmpeg 2 pass encoding method rather than the xvid one when using libavcodec's internal mpeg4 encoder?

[nicksteel]

I'm testing ffvfw with an NTSC anamorphic Widescreen 2.35:1 DVD. I wish to make a test NTSC anamorphic Widescreen 2.35:1 DVD. I'm using Forcefilm in DVD2AVI. My avisynth avs, which I load into VDub, only contains the mpeg2source line with the d2v file.

I run Pulldown.exe at the command prompt as: "pulldown myfilmIN.m2v myfilmOUT.m2v" to get 23.976fps.

TMPGEnc Author says that the GOP is "too long" (must be 18).

Which settings, if any, should I change in ffvfw?

What settings should I choose in DVDPatcher?

Sorrrrrry about all the questions, but you can see I'm a bit confused. My encoding is usually confined to PVR250 TV captures, but I'm using this method to figure out how to use ffvfw.

I would sincerely appreciate any aid / advice.

Any news on this codec?

I'd like to hear some feedback on MPEG-1/2 encoding with FFVFW, seems to have potential versus TMPGEnc and CCE.

These guys have been crazy about it

http://kvcd.net/forum/viewforum.php?f=68


But from what I heard it's not very stable in the 2-pass and rate control arena (I'm just talking about MPEG-1/2 here).



Best regards,

Look on kvcd.net for some settings at:

http://www.kvcd.net/forum/viewtopic....r=asc&start=16

I've used the KDVD settings with very good results. The only real problem is the maximum bitrate sometimes generated. It hasn't affected my standalone player so far. I do PVR250 analog cable TV captures to DVD with a couple or three movies per DVD. Very good results.

My goal wasn't really FFVFW but FFMPEG, until I saw this post

http://kvcd.net/forum/viewtopic.php?p=62465#62465

I wanted to use FFMPEG or FFMPEG-based solutions like Mencoder for DVD backup under Linux/FreeBSD because it's 4 times faster than mpeg2enc/mjpegtools-based solutions like transcode.

I have a thread on that subject. But in Kwag's opinion FFVFW already corrects some stuff from FFMPEG, it's not just a frontend.

I'm reading every post I can find concerning rate control. I really like ffvfw's quality, but realize some people are experiencing high bitrates. Perhaps someone will discover a solution.

[jcsston]

Would it be possible to add DV decoding to ffvfw?
The only other free DV VFW codec I know of is the Panasonic one which only does RGB in/out and it's YUV->RGB routines are not the best in quality.

[celtic_druid]

It already has it, well at least ffdshow's VFW decoder does.

Can I somewhere download a copy of ffvfw.dll with MakeAVIS? I have problems with MakeAVIS deliverd with the latest fddshow (the first time I tried MakeAVIS). A guy in another forum has the same problems as I, and his problems began at the momemt ffvfw was integrated in ffdshow.
The problem is that DVD2SVCD cannot read a fake AVI made by MakeAVIS. In the preview window, a AviSynth error is showed: could not decompress frame 0.
So my question: Can I download somewhere the latest version of ffvfw.dll with MakeAVIS?

The same question in 3 different threads - this is usually called "crossposting"...

Well, here I asked where i can download ffvfw. In the ffdshow forum, I asked for a solution for the latest version.
And the third post.. I will edit that post

I have rather weird question: Can avisynth open makeAVIS avi files?
I cannot test it right now.

That version does not extract the audio and puts the extracted audio in the fake AVI. That's necessary for DVD2SVCD. Has anyone another MakeAVIS version?
