New FFDSHOW with integrated FFVFW
New FFDSHOW released by Athos:
http://forum.doom9.org/showthread.ph...185#post454185 http://athos.leffe.dnsalias.com/ffdshow-20040304.exe I just downloaded it a few minutes ago. I uninstalled previous versions of ffdshow and ffvfw and installed this last "integrated" version. It works pretty well in graphedit. Observations so far: Slight changes in ffvfw settings interface (mpeg2 ME). At least 150% speed increase on my machine (athlon xp 1600) at mpeg2 encoding. Happy download Bye marcellus |
Nice link marcellus :wink: ,
I already downloaded it, but still didn't install. I'm now mainly focused in understand/improve mencoder encodings. But I'll keep an eye on ffvfw :lol: |
Thanks Marcellus :)
Haven't had time to try it but I already installed it. Only thing is it's lacking the makeAVIS on this version :cry: Hope that Athos and Milan fix that soon. Cheers |
I might do something wrong but I got ridiculous 31 high quantization in 2nd pass encoding. I'm not 100% sure yet but I think the 2nd pass encoding is screwed up in this version. :cry: :cry: :cry:
But I'm still testing. Did anybody tried it already? Anyway, the speed increase is amazing. The one pass CBR is working like it used to. I dont't know if it still gives bitrate peaks, but I think it's likely to be that way since it hasn't any max bitrate setting. The VBV issue remains. It has some new features like quantizer noise shaping (slooooow) and libavcodec noise reduction. New features :arrow: infinte amount of tests needed :twisted: marcellus |
Testing it out..marcellus, I am trying to use graphedit for the first time...I cannot figure out how to end the graph....you stated something like "dump" in your guide, but I cannot find anything like that...I did try "file writer" under direct show filters, but all that does is create a very small file...And you explain this process more clearly??
Also, is there a way to process one file after another, like batch processing in Dirtualdub Mod.... Thanks.. |

About batch processing I don't know much but I don't think so. Graphedit is afterall a debug tool, it hasn't many features. It would be cool if somebody could make a graphedit on steroids with features like that and others, but untill then... marcellus EDIT: forget about Null Render, it limits encoding speed to the real FPS of the source (for me it limits it to 25 fps -PAL, with file writer I get even 34 fps) |
Call me stupid and lock me in the barn...but, I cannot figure out how to get this new intergreated version of ffshow (and ffvfw) to work with virtuldub...It doesn't show ffvfw under the compresion tab anymore...sorry, marcellus, but if Graphedit does not have any support for batch processing then it is not really an opinion for me...
I am sure it is something really simple, I just can't figure out what that is... |

You cannot see this new "FFVFW" in Vdub because it hasn't VideoForWindows interface anymore, it has only DirectShow (so we are improperly calling it now "ffvfw"), which Vdub cannot see. If I'm wrong somebody correct me. I'm not bothered by this twist since I'm not using Vdub to encode (nor makeavis for that matter) but obviously I'm one of the few. I'm worried about this since it casts away potencial or actual ffvfw users... I hope ffvfw will be back again and makeavis too... EDIT: Or, even better, Vdub could start working with DShow since IMHO VFW is kind of obsolete... marcellus |

c:\program files=won't work c:\video=works great, opens in vdub. Just testing it now and at first glance it is approx 25% faster Edit: up to 100% faster at times We'll see what it looks like soon.... Edit2: looks good. |
Great news everybody!!! :D :D :D
New ffdshow build: http://athos.leffe.dnsalias.com/ffdshow-20040329.exe Guess what: in ratecontrol tab we have now: maximum bitrate :D minimum bitrate :D vbv buffer size :D I just downloaded it, I didn't tried it yet but I'm so excited!!! I hope it solves many problems! I guess our prayers have been heard. bye marcellus |
I have to lower the enthusiasm a few notches down :cry:
The VBV setting is definitely working, now I can easyly obtain VBV of 112 in BV. But for min/max bitrate, I don't know, maybe I'm doing something wrong (although I doubt it) - for any other value than 0 (meaning infinite) I get a constant Q of 2 and bitrates way much higher than expected. I don't have much time on my hands right now so I did't let it finish an entire file encoding, but I think it's pretty obvious that the thing isn't working as I expect. marcellus |
Marcellus,
I think this version fddshow/ffvfw is a CQ encoder in every aspect. The only way to change anything in bitrate/filesize/etc. is to rize the minQ. Otherwise it's encoding everything at cq=2. VBV problem however is soved with this build. So, no min/max bitrates, or even no bitratecontrol what so ever....... I'll stick to Mencoder for now although this fddshow build is very fast compared to the older ones. Staigerpaip |

To conclude: VBV is not an issue anymore, min/max rate still unusable, the rest is in it's place as usual. bye marcellus |
