New ffdshow build (?)

[Isochroma]

@clsid: Yes, there is a specific reason why I use the MS DS DV filter, in fact there are two: 1. ffdshow is about 15% slower, and 2. the output image has very bad chroma upsampling or something like that, it looks really bad compared to the MS filter.

Also, there's no need for ffdshow to even handle DS DV playback because at least windows xp and probably all others back to 98 have it builtin.

So it would be fine if the DV DS filter were entirely removed from ffdshow, because it is unnecessary, performs poorly, and has lower quality than the already-installed MS version.

In contrast, the ffdshow VFW DV encoder is excellent, better than either MainConcept or Pinnacle, so it is my new choice for DV encoding :)

[Isochroma]

@drevil_xxl: The build you sent me doesn't allow the checkboxes in "Custom" installation to be unchecked - I don't need the Dscaler plugin.

After testing, I must say there is something seriously wrong with this build. It plays back DX50 and XVID (no filters or postprocessing) at about 2.7 fps on my 2.33GHz processor. This occurs with output queing on and off. This is true with vmr 7/9 windowed and renderless using rgb32 output.

Using yuy2 output, playback is at 15fps (should be 23.976) using 100% cpu.

[JarrettH]

This may or may not be a bug. I use the save to file... to save my presets when I reinstall ffdshow. For the third time now when I try to restore anything that has avisynth code in it it only saves the top line, sometimes only a portion of it. Try it yourself :cool:

Anyone want to try this out :-D

Try turning the audio filter off and using some other decoder for it. I disabled it and my cpu usage halved, with no decoding and no filtering, just raw audio (decoded by MPC) passed through. o.O Something weird is up this build, will look into it when I'm done watching stuff.

List of known issues in revision 345:

1) VC-1 does not work. ffdshow isn't even placed in the DirectShow graph. (reported by clsid)
2) VMnc crashes with "Integer devision by zero" exception. (reported by clsid)
3) Some SVQ3 files play with artifacts / color shifts / totally messed up picture. Same issues in FFplay. (reported by clsid, Peuj)
4) When outputting the audio to AC3 using the ffdshow AC3 encoder there are a lot of downmix overflows. The sound seems to be distorted as if the volume is to high. (reported by TFM_TheMask)
5) Output queue enabled + VMR9 renderless + RGB32 + specific video cards + pause = blackout problem
6) Wavpack decoder crashes on this file (http://rapidshare.de/files/34646550/SoC__XviD_WavPack_MP3_-007.mkv.html). (reported by clsid)
7) The following encoders are possibly broken: MPEG 4, MPEG 1, MPEG 2, h.263, H.261 and DV. (please confirm) (reported by clsid)
8) It seems there is no way to disable snow decoding in ffdshow. Also ffdshow crash when i try to play snow (encoded with latest mplayer/lavc). (reported by Yong)
9) mpc/ffdshow.ax crash when i try load the impulse file (???) with the Convolver audio filter. (reported by Yong)
10) Access Violation in ffdshow on Windows Vista. Details (http://sourceforge.net/tracker/index.php?func=detail&aid=1567236&group_id=53761&atid=471489). (reported by Microsoft Windows Reliability team)
11) MSS2 WMV files: MPC crashes when info & debug window of ffdshow is active. Sample file (http://ftp.mplayerhq.hu/MPlayer/samples/V-codecs/MSS2/mss2_speech.wmv). (reported by drevil_xxl)
12) QPEL bugs and colour/block trains/displasement. Details (http://sourceforge.net/tracker/index.php?func=detail&aid=1568940&group_id=53761&atid=471489). (reported by drevil_xxl)
13) Avisynth error message is shown only once. After the message is shown and closed, I can put all kind of nonsense in the ffdshow AVS section but no error message would be shown later. Also suggestion: if AVS exception is raised, then not only show the error message, but also automatically uncheck Avisynth section in the ffdshow. (reported by Egh)
14) Loading IFO file in MPC and seeking thru the video instantly crashes MPC. Seeking thru VOB file is fine.(reported by DSP8000)
15) ICL9 builds of ffdshow.ax crash on files created by a specific (?) old revision of x264. Funny thing however is that the files play without crash if you first play a good file and then play a 'troublesome' file in the same player instance. Also no crash when using a plain unoptimized debug build. Sample file (http://rapidshare.de/files/35447656/sample.mp4.html). (reported by clsid)
16) ffdshow crashes when decoding stereo 192kbps mp3 using AuD-X lib. (reported by drevil_xxl)

ToDo:

1) Fix known bugs (duh!)
2) H.264 deblocking options should be moved to 'Decoder options' as single combobox with "standard deblocking, no b-frame deblocking, no deblocking" options in it. (suggested by Egh)
3) Speaker setup page in InnoSetup installer
4) Update libavcodec vorbis
5) Update libavcodec SNOW encoder
6) check if there are other ffmpeg parts that need updating
7) keyboard control feature request (http://forum.doom9.org/showthread.php?p=881108#post881108) by therealjoeblow.

Hardware deinterlacing

Hardware deinterlacing working flawlessly. Thanks Haruhiko.

[Egh]

I cannot understand. Why is it bug?

cause all works well. i.e. in AVS section the script is legitimate, but the error message is shown because mpc + ffdshow is starting (and imo video is not yet feed to AVS).

p.s. any ideas about fullrange param from the function?
Does anybody else haev a clue? What I mean is yuv2rgb.c declared function

int yuv2rgb_c_init_tables (SwsContext *c, const int inv_table[4], int fullRange, int brightness, int contrast, int saturation)

[foxyshadis]

fullRange=0 : TV-mode conversion (16-235->0-255)
fullRange=1/-1 : PC-mode conversion (0-255->0-255)

[Egh]

fullRange=0 : TV-mode conversion (16-235->0-255)
fullRange=1/-1 : PC-mode conversion (0-255->0-255)

LOL :) I asked cause I'm releasing a video converted to PC range (and encoded with x264 in that range!) soon. But what I really want to know, whenever ffdshow is able to properly handle it, since that function is used for RGB32 conversion, as I understand. If ffdshow doesn't set this parameter properly when receiving PC range video (for instance it can be YV12 from CoreAVC with "VMR9 colors correction" on or decoding result from h264 when video is fullrange) then conversion of fullrange video to RGB32 colorspace might be wrong. Naturally that's because the function actually converts from TV range when fullrange == false.

[Kador]

Hi

I don't know it it's related to the current discussion, but I've spotted a weird effect : when I activate the resize filter , the color range changes (basically without it looks dull, and with it looks oversaturated), whatever the output format I use (YV12, RGB32) and whatever the resiez filter (lanczos, ...).

I'm using ZP latest and VMR9.

It does not happen in overlay mode. Actually another phenomenon happen in overlay (same setting change : resize) : the colors of the pictire change slightly, they look more "yellow" (warmer) when the resize filter is activated.

[foxyshadis]

cause all works well. i.e. in AVS section the script is legitimate, but the error message is shown because mpc + ffdshow is starting (and imo video is not yet feed to AVS).
Yes, when the script is initalized it seems to be feeding an incorrect colorspace in, giving a popup error, but the script functions normally after. So I guess the error message has to be delayed until the video starts playing, or something.

[signatory]

I never had any install problems before. But now I get this odd message. I undeleted ffdshow before I ran the install.

ffdshow_rev312_20061002_clsid.exe

http://img81.imageshack.us/img81/7226/errorffly5.jpg
I reinstalled Windows Installer 3.1 for XP also. Still same error.

Any ideas?

[Egh]

Yeah, I tested it myself and found out that the problem was different colorspace upon initialization (and if an avs filter used in the script requires YV12 then of course error message is show).

I wonder why this happens. Might be another bug :)

A potential cure would be not to delay the message, but AVS section initialization.

[JarrettH]

When I install your new builds, clsid, is it ok to just install over the previous one? Should I uninstall first?

[clsid]

You can just install on top of your current install.

[Romario]

One big question: can ffdshow from tryout SVN branch decode Screen Recorder codecs, like:

TSCC, MSU Lossless Video Codec, FRAPS Video, MSU Screen Capture Lossless Codec, AlparySoft Lossless Codec 2.0, CorePNG 0.82.

If answer is no, you can consider this as feature request. Thanks, and live long and prosper, my friends.

[foxyshadis]

It should be able to do CorePNG, but ffmpeg doesn't have decoders for any of the others yet. (And we can't just bundle them with ffdshow, sadly.)

[clsid]

It is also able to decode TSCC (=Techsmith).

[Romario]

Thanks. One more question: why ffdshow decoding depends only from ffmpeg revision?

[foxyshadis]

It's not the only one, there are others like libmpeg2 and libfaad, but ffmpeg supports tons of different codecs easily. And ffdshow currently only uses open source code (except for certain buggy filters); even if licenses could somehow be obtained to distribute commercial closed codecs, I doubt many people would be happy about that.

[ForceX]

I can no longer use FFDshow's video post-processing on the newer builds. Enabling postprocessing on every build since September does...nothing. No visual sign, no extra CPU utilization. Previous builds work just fine.The last build with working PP I checked was ffdshow_rev2546-96_20060827.exe by clsid. Everything after that doesn't let the Post Processing work. Not even ffdshow_rev2546-127_20060902.exe by clsid, or any other later builds (by VM9 or drevil) for that matter.

I use MPC 6.4.9 rev.611, VMR9 renderless on WinXP SP1, RGB32 output, on an Athlon64 machine.
Changing the player to BSPlayer, changing output colorspace or changing the renderers (VMR9 rendered, Overlay Mixer, VMR7 etc) does not fix the problem. Nor does turning on/off output queing. Whether I use FFDshow as a decoder or generic video filter, I can't use the PP function.

The only time PP works (that I checked) was when decoding FLV1 with LAVC.

One thing I noticed is that the builds where the "H.264 deblocking" option is removed from the PP page (since evry build in September) are the builds that do not work. Maybe that is the problem, because H.264 deblocking stops any other PP deblocking? Can I do anything (any registry setting changees?) that would fix my problem? Thanking all of you who are putting such a great effort to continue improving FFDshow. :)

[JarrettH]

do you really need post processing? anything i've tried in ffdshow in the post processing tab severely degrades quality. probably the best non-destructive tweak you can do is lanczos resize.

[ForceX]

I do use the resize filter for low resolution videos, but use Spline instead of Lanczos. Everywhere it says Lanczos is the best resizing method, but I don't see too much difference between the two, and I find Lanczos is too sharp, tends to "amplify" noise and cause "aliasing" effects. (not in all cases) However, may I know the the "Number of taps" thing does?

I know that the FFDshow Deblocking is not that good and in most cases degrades videos which are of high-details in the first place. However, I have some old, low-res videos (Mostly MPEG ) which are horrendously blocky (Don't blame me, I didn't encode them.) and noised, and the deblocking/deringing did help somewhat. And the FLV1 videos from Youtube are also very disturbingly blocky when played with the FFDshow LAVC decoder. Good thing that Deblocking does work on FLV1, but not on others. I generally have auto-preset loading for those blocky videos, and I'd like to use them.

[foxyshadis]

Really? PP with xvid, divx, and div3 sources all has an effect on mine. (I cranked it to 200% just to notice quicker.) Are you using it on raw video (ie, video that's been decoded in something besides ffdshow, like MPC's internal decoders)? I specifically disabled it because it was pp'ing lossless video, but I didn't realize it might be necessary if ffdshow is used only as a post-processor. It's far less effective than it would be when natively decoding, because it doesn't have certain hints, but oh well.

I made the relevant change, I'll look at providing some GUI ("Apply only when ffdshow decodes/Apply to other decoders") or some registry hack at some point if it starts to irritate me again.

What does resizing have to do with post-processing junker video?

[jigc]

do you really need post processing? anything i've tried in ffdshow in the post processing tab severely degrades quality. probably the best non-destructive tweak you can do is lanczos resize.

i faced the same problem with ForceX.
PP didnt work for new tryout.

i use tv tuner to recode tv programe in mpeg2. it always has slanted lines noise (i dont know how it is called).

but i found that PP with delock (H) and deblock(V) only for luminance, strength of 25~30 greatly reduces the noise (accurate deblocking is checked too).

btw, i call PP of ffdshow from AVS for x264 encoding.
i hope it is fixed.

[foxyshadis]

Have you tried native avisynth deblockers? Such as Deblock_QED or FunkyDeblock, which may be somewhat faster and will be higher quality too.

And for your specific frequency interference problem, defreq sounds like it would be aptly suited, but it takes a bit of effort to get going. Odd that deblocking without deringing would help with diagonal lines.

Anyway wait for the next build and PP will work from other inputs.

It's far less effective than it would be when natively decoding, because it doesn't have certain hints, but oh well.

Oh, sorry about that. >.>; PP does work while using FFDshow (either LAVC or Xvid decoder) to decode divx/xvid content. However, I do not use FFDshow to decode those, I rather use the DivX decoder, and most of my DivX videos are high-quality, and DivX can use it's own Post Processing, therefore the presets are made to not use PP on them. However, FFDshow does no longer use PP when processing raw (uncompressed)/decoded video from any outside source and any colorspace. And no, FFDshow PP does not work when decoding MPEG 1/2 videos using FFDshow libMPEG2 ( LAVC does work, but I prefer to use the libMPEG2 or the MPC/OpenSource decoder), and the MPEG 1/2 files are the ones needing the PP.

Now that I've done more extensive checking, it seems FFDshow currently only uses the PP filter when using LAVC or XviD as internal decoder, and no PP when not decoding.

I made the relevant change, I'll look at providing some GUI ("Apply only when ffdshow decodes/Apply to other decoders") or some registry hack at some point if it starts to irritate me again.
Thank you very much for your consideration. ^^

What does resizing have to do with post-processing junker video?
Not much, actually. Was just wondering what's all the fuss with Lanczos about. >_<

Another bug I noticed, if using CoreAVC 1.1.0.5 for video decoding with RGB24/RGB32 output, and using FFDshow as a filter (for resize/sharpen), the video looks upside down. Does not happen if FFDshow is not used.

Oops, sorry, didn't notice that post.

Thanks for your quick response. And I too would try using the avisynth deblocker, but I'm afraid I'm not much proficient in AVS scripting yet.

It's hard to express how grateful I am for ffdshow. It enables me to take my Microsoft operating system, and then use my player of choice to greatly expand what media I can enjoy. It is lightweight, fast and free. :)

I have some feedback:

1. Im not sure of the wisdom of overwriting default installed codecs signed and supported by Microsoft with ffdshow ones. Like, why use the ffdshow mp3, lpcm mp1 and mp2 audio decoders by default? I think it is safer and easier for users to install ffdshow by default settings with only adding to the support media types, not changing default operating system codecs.

I know people who installed the game oblivion had issues with earlier versions of ffdshow because of it overwiting default codecs supported by the operating system itself.

2. Having more than one installer confuses the users and dilutes the effort to improve the quality of the installers. I think a more focused outcome is for the devs to pull together on one install package.

I saw on the google summer of code that one of the ffdshow projects is for VC-1.

[land]

Hi,
I'm newbie and I'll be very grateful to those who help me.
I'm trying to build ffdshow but I'm having some problems. I want to compile it with msvc6. I have install Microsoft Platform SDK Feb 2003 and DirectX 9.0 october 2004 (these are the latest updates for vc 6.0, isn't it?). After that I register visual studio and I check that in vc6 the paths are correct.
I want to use ffdshow with VirtualDub, that's mean that I only need to compile ff_vfw.dsw or must I compile something first?
When I compile ff_vfw the errors I obtain are:

Error executing cl.exe

Does someone know how to fix that?

Use MSVC7.1 (8.0) or GCC 4.0.3

[land]

I can't use msvc7.1. I'm working at university and I can only use free programs and msvc6.0. I have gcc 3.4.5. I tried compile ffdshow with msys but I didn't know how to do it

ffdshow can be compiled with GCC 4.0.3 - MinGW:
http://gda.utp.edu.co/~ceniza/GCC-4.0.3/
http://sourceforge.net/projects/mingw/
Set up enviroment for MinGW:
http://csjava.occ.cccd.edu/~gilberts/mingw/
You'll also need the following:
binutils, mingw-runtime, nasm-0.98.39, msys & w32api.

Don't forget to convert the DirectX SDK Lib!

Hi,
I'm newbie and I'll be very grateful to those who help me.
I'm trying to build ffdshow but I'm having some problems. I want to compile it with msvc6. I have install Microsoft Platform SDK Feb 2003 and DirectX 9.0 october 2004 (these are the latest updates for vc 6.0, isn't it?). After that I register visual studio and I check that in vc6 the paths are correct.
I want to use ffdshow with VirtualDub, that's mean that I only need to compile ff_vfw.dsw or must I compile something first?
When I compile ff_vfw the errors I obtain are:
Does someone know how to fix that?
Should we remove vc 6.0 files from ffdshow?

1. Im not sure of the wisdom of overwriting default installed codecs signed and supported by Microsoft with ffdshow ones. Like, why use the ffdshow mp3, lpcm mp1 and mp2 audio decoders by default? I think it is safer and easier for users to install ffdshow by default settings with only adding to the support media types, not changing default operating system codecs.

I know people who installed the game oblivion had issues with earlier versions of ffdshow because of it overwiting default codecs supported by the operating system itself.ffdshow does NOT overwrite any codecs on your system. It only has a higher merit than other filters. So if you enable a format in ffdshow, then ffdshow will be used to decode that format. If you disable it, your player will use another filter.

It is possible in the options to entirely disable the use of ffdshow in specific applications. I'll change the installer to do so for Oblivion.exe

What is impulse? How ffdshow is connected to covcolver(?) filter?

What a lame typo:p
Sorry.
u can download impulse files here:
http://www.sjeng.org/foobar2000.html

Im not sure its compatible with ffdshow internal convolver filter,
but its works with other external dshow convolver filter:
http://convolver.sourceforge.net/

I remember older version doesnt crash when loading impulse file, but it just dont work.

Thank you. Now I can reproduce the problem.

A (stupid?) question about the installer:

The "Application plugins" -> "AviSynth" it's a plugin to be able to use AviSynth, it doesn't install AviSynth ?
