ffdshow development #2

[Irwin]

Sorry OT here but

Where i find in source http://cvs.sourceforge.net/viewcvs.py/ffdshow/ffdshow/src/imgFilters/ sharpen-swscaler filter?

[Leo 69]

Hey guys!Does anybody know if videolan developers included
the latest ffmpeg (with b-frames support)into their last nightly build of VLC-player?I got a slow modem,so I can't just check it out,you know:D Besides they seem to be sleepy on their forum - no replies,etc...
Thanks in advance
Leo

-----------addition---
They've just submitted a reply where they say the ffmpeg update for VLC is only made once in a while...Gouch..I can't wait any more...

[Leo 69]

I am very disappointed that the latest ffdshow doesn't play Recode's
mp4 files smoothly (those which are with b-frames). Well, it works,
but with sporadic freezes, as if I got a slow PC.But processor load is only about 50% on my Athlon 2800+. Does anybody have similar problems?

Cheers
Leo

nope seems nigtly vlc build uses older ffmpeg, although i have no problem playing with ffdshow latest, well if weighted pred not used

[giandrea]

I compiled the last Mplayer snapshot, that I suppose has the last FFmpeg CVS, because this night I encoded a short clip with NeroDigital AVC (B-frames, no weighted prediction, no psichovisual and no deblock) and it plays smoothly.
The only thing that I noticed is a possible lack of quality during playback, because the clip was encoded at 1000 kbps and its quality was worst than an Xvid clip encoded at 1200 kbps expecially in dark areas. Is that possible?
This is a screenshot, Xvid on left, Nero AVC on right, notice the right bottom corner of the frame, and how it is much more detailed in Xvid.

[netchris]

Giandrea : Yes nero avc has a problem with dark areas, its like wrong use of psuchovisual (though anomalies in black are still there even when no psycho are used).
Its an excellent progress to be able to play nero's files with ffdshow!
Well done to the coders.
It aint yet perfect but very close to it :)

[Leo 69]

Something is definetely wrong with b-frames in ffdshow guys,I'm sorry
It freezes ALL the time!
If you don't believe me here's my sample.Simply play it first in ShowTime and then in any directshow based player using ffdshow decoder.I guess you'll see the difference:rolleyes:

@ leo: i think u are not the only one who have problems with this....
but give the devs some time to fix that ;)

[giandrea]

Leo: I just compiled mplayer from CVS, and your clip plays smoothly! :confused: What are you using for playback? Anyway i suppose that it is a 12.5 seconds clip.
bye,

sounds like you speak from experience ;)

[Leo 69]

@ giandrea

I'm using ffdshow-20050105 from celtic-druid & either MPC or BSPlayer.
The playback is really choppy :( I very doubt that smth is messed up
in OS,well I know how to keep it in repair..
Anyway could you upload your Mplayer build somewhere and give a link? That would be cool:)

Cheers mate :)

[celtic_druid]

Two factors though if you are playing mp4's. What splitter are you using? Perhaps try an avi sample and see if you have the same issues.

[Leo 69]

@ celtic_druid

Those avis created by x264 play absolutely fine!!!
Besides I can't see the splitter while playing .mp4..Is this normal?

http://images.people.overclockers.ru/17522.png

I guess not :confused: Help!

[Taurus]

On a Win98 machine using ffdshow-20050105 on mediaplayer classic every avi, h.264 crashes mediaplayer @ closing the program.
ff_acm.acm is located in C:\Windows\system and in ffdshow program dir.
It is called via system.ini.
Former ffdshow installations didn't show this behaviour(tested on ffdshow-20041012.exe and ffdshow-20040808.exe.
Disabling the call of ff_acm.acm in the system.ini solves the crashes.

Cheers

[BlindWanderer]

I may just be crazy but SPP deblocking seems a bit heavy when used on internaly decoded video from x264 compaired to xvid. Haven't done much testing on this. (I was noticing major differences with the faces; was running SPP with processing strength at 128, soft threashold off, automatic QC turned off, and the presets bar full forward)

Noticed on the Last Samurai samples found in the sex264 thread.

H.264 is internally deblocked. Hence the "deblock" parameters you get to set while encoding. If you deblock it again, of course it will end up blurry.
(Yes it's less flexible this way, but in-loop deblocking improves the quality of motion compensation, so less filtering is needed in total.)
(Note that ffdshow hasn't implemented H.264 in-loop deblocking for B-frames as required by the standard, so that doesn't reflect the true quality.)

So what soulutions do you suggest for a full featured playback?
Does one need to have a win32 system and neros dshow filters from latest Recode? And how to ensure that the filter is used in a dshow based player?

Hellfred

[akupenguin]

I hear that VSSH works.
But I don't want to resort to binary DLLs, so I'll just finish libavcodec. It shouldn't take too long.

[708145]

SPP strenght is relative to the average quant per frame.
maybe it doesn't understand h.264 quant range and filters like ASP quant 18 (very heavy) for AVC quant 18 (should be light filtering).

Just a guess.

That would be great and highly appreciated.

Whoa - that'd be a tad heavy... :D

By the way - will there be an update of SmoothD sometime in the future, or is it a bit dead for now? ;)

np: Pan Sonic - Vähentajä / Diminisher (Kesto (234.48:4) (Disc 1))

I'm doing one project at a time. But I'll debug SmoothD after the current one (ELDER).

Thanks for the info.

[bond]

actually you might want to know that akupenguin (aka pengvado) also implemented weigthed prediction support to ffmpeg now too.
thanks a lot!!! :)

[Leo 69]

@ Bond

At last! Now we'll wait for celtic_druid's response (updated ffdshow) :D

[Franky]

Has anyone been able to download celticdruids latest build (20050111) yet, and if so, could that person please mirror it?

[BlindWanderer]

ffdshow build 20050111 crashes on raw video, problem not present in 20050105 (tried two different sources of different stream formats, wmv3 in mkv & mpeg2 in mpg). The crash was silent.

[Yong]

same here, but it don't want to play my video files at all...
crash ffdshow.ax...
I will send a bug report to milan.:)

[kurt]

it chrashes also by decoding xvid... like BlindWanderer said no problems with ffdshow 20050105

[Ark]

For me lastest build 20050111 is broken, it install correctly (altough a bit slow on the x264 dll file...) but i can't access any panel, a pop-up window of Rundll32 appears saying that an exception has occured on ffdshow.ax....

[celtic_druid]

11.01 was compiled with VC7, 05.01 was compiled with VC6 which I think explains the problem with RAW video as it seems to involve msvcr71.dll.

Might put up a new VC6 build, looks like libavcodec has been updated to.

No problems here decoding XviD by the way.

Same problem here, cant open any video format or config panel.

you are right - problem here is if i enable "picture properties" (like in previous build) then zoomplayer crashes...

[celtic_druid]

No problem here with picture properties enabled, although I am running a newer compile. Also no issues when enabling for RAW video.

Will put it up later when I am done compiling libavcodec.dll, etc. and have built the installer.

By the way, celticdruid - exactly what connection does your server have? Cable?

Whenever I downloaded something from it in the last few days, I was lucky if I got more than 1 or 2 kB/sec - when I could connect at all... :(

(I hope you don't take this as a complaint; I'm just curious, and for getting the files eventually there's download managers... :))

[CruNcher]

New ffdshow crashes here directly after trying to load a video (mpc closes) hmm it crashes imidietly becouse the OSD is active, disableing it i can at least watch the video but when i try to access the config panel, it's crashing again :P

[celtic_druid]

Works fine here Win2k SP4 with an Athlon 64 3500+. OSD works fine. Config works fine.

Connection is only 512 ADSL and I agree it is way too busy, way more than I ever really intended. I have even gotten over 9,000 hits from people using google to search for pirate movies to download.

I only really set the server up for testing php scripts, etc.

[billou2k]

Cruncher: Got the same problem here with 11/01 ffdshow version. It doesnt crash with every codec but xvid is one of them. Going back to 05/01 version works fine.

[Leo 69]

ffdshow is now updated (20050113),weighted prediction seems to be supported but still there remains a BIG problem with b-frames in Recode's .mp4 :(

[CruNcher]

huh borks again ? the 5th jan build displayed b-frames in recode encodes nicely and yes i used 11th jan build trying the 13th now geez changes fast :D

B-frame are still working weighted prediction works too very nice but every b-frame now with activated OSD the OSD gets curupted looks funny :D

[Bluedan]

Opens multiple instances of ffdshow-video when I try to playback an matroska file containing DivX video with Core Media Player. With XVid it's the same. File plays fine though. Didn't alter any settings in ffdshow.

In the first place crashed player until I disabled raw video support.
No difference when using gabest mkv splitter or alternative from Haali.

[Leo 69]

@ CruNcher

What splitter are you using for playback? :confused:

Just a wild guess, two instances of ffdsow, one for decoding video, and one for audio? Test: Strip the audio out of one of your clips and retry. If ffdshows numer of instances wents down to one, you know what is up.

Hellfred

EDIT: If you have an avi-source, I would suggest VirtualDubMod to create a new file of just some hundred frames. Set video to direct stream copy and disable audio track via Stream -> Stream List. File should be ready to test just few minutes.

Make sure that "only one" is set in:
ffdshow configuration-->Codecs (at the botton)

[celtic_druid]

Hmmm, looks like my compile just missed out on:
"hack to set correct frame timestamps for b frames with nero splitter"

[BlindWanderer]

I assume that fast rendering for the OSD doesn't keep a backup of the original frame; using the modified frame with the decoder. While having it turned on I noticed block movement containing OSD text. Could we get a tooltip about this for the check box?

[Yong]

Special SSE version, download here (http://cutka.szm.sk/files/ffdshow-20050112.exe)
:) :) :)
Anyone here may try to playing your lovely DVD with ffdshow(Decoding MPEG1/2 with libavcodec can't wotk, please change the MPEG1/2 decoder to libmpeg2),
see if it can work or not:p

A clean uninstall/install solved it. Sorry for the waste of letter soup here. :p

I have some kind of choppy playback now but A/V stays in synch. CPU consumption is ~35%.

Decoding AVC(in mp4) created with Recode.

:confused:

[Koti]

Just a big "thank you" to all the ffdshow dev's and compilers

ffdshow-20050117.exe (celtic druid's) plays (using nero's parser/splitter) recode created avc.mp4 files (all options enabled in nero encoding tools) perfectly!!!!! :D :D :D :D
