ffdshow tryouts project: Discussion & Development

[leeperry]

oh, and I dunno what the defaults are...but I think it'd be good that you set liba52 and libdts as default decoders as they both decode in 32float(libavcodec only decodes in 16int, which is much lossier if you use post-processing).

[mark0077]

BTW, my first filter in fffdshow is YADIF("process frames flagged as progressive" disabled), so ideally it should only turn itself on for interlaced content...but it's been processing progressive content as well lately :o

I think it started to happen after I upgraded to a newer version...how can I check if ffdshow detected an interlaced source? I loved when it was fully automatic, I'll try to change the MPEG decoders maybe....I think it was working fine w/ the MPC-HC decoder, which seemed to set the interlaced bit properly.

Are you by any chance having the problem with DVD's? which you might already know don't have reliable flags. You will know if yadif is in use if you have "Double framerate" on, you can then see in mpc-hc's status, the frame rate will be 50.00 instead of 25.00 for example.

Anyone know if grab should catch these second frames that are output from yadif, seems like they arn't being grabbed in the current versions.

yes, I had the problem on DVD's...but also on progressive AVI files?! apparently something's messed up w/ the flag, or in the latest ffdshow revs/my user settings :o

if you enable YADIF, it doesn't turn on for AVI files for you? and I've got some interlaced WMV files where it doesn't.

I guess automatic deinterlacing is not quite doable..

[diizzy]

Have you tryed with reclock? I'm not sure, but maybe reclock could do that for you...

It does indeed (checkbox), although it seems to have some bugs also. First video I tried made it hang, probably due to SPDIF. Would be lovely if that feature could be adapted to ffdshow although I don't see any source code available for reclock.

[yesgrey]

First video I tried made it hang, probably due to SPDIF.
If you read the option it says "for PCM sound", so probably you cannot use it with spdif... Have you tryed it with PCM sound?

[albain]

As usual, a big thanks to the developers and contributors for keeping this project alive.

I just have a small question in case I'm missing something, this "issue" is on both Vista and Win7 if you have your computer hooked up to a receiver with HDMI. If you set your speaker set to 5.1 Windows always outputs it as 5.1 (multichannel) but with only L,R active if you have a stereo source. The workaround would be to enable some surround effect in either ffdshow or in Windows (I only think its available in Windows 7) if you want sound in all speakers. Is it possible to force regular stereo output for 2 ch sound like when you set 2 speakers in Windows so the stream is truly 2ch?
That way you can use upmixing features on your reciever.

Thanks in advance
//Danne

This is possible if you enable autoload condition on ffdshow audio :
if nbchannels = 2, define a preset with mixer set to 2/0

[mark0077]

Hi all,

I am trying to use the ffdshow encoder to make lossless clips from adobe premiere. What could I be doing wrong.

Using ffv1 in avi, the exported clip plays the first 5 seconds and then crashes.
Using lossless jpeg in avi, the exported clip initially comes up as pure grey image, then shows a streaking effect and crashes.
Using H264 losslessin avi, the exported clip plays fine the whole way through, but its suspiciously small, and shows horrible video corruption the whole way through.

I am exporting a 60fps 1024 x 768 clip which exports fine completely uncompressed (not using ffdshow encoder).

My aim is to get my clip approx 30% smaller than the uncompressed lossless version so that my hdd can keep up with the clip, 4ghz core i7 should be enough I hope to decode this on the fly.

I am using ffdshow and mpc versions released today, 3060 and 1245. h264 lossless is the only one that I can actually see some output, although its badly garbled.

This would seem to be the relevant MSDN doc (http://msdn.microsoft.com/en-us/library/ms790524.aspx) if a developer had the time/interest to add a "match speaker config to output" option to ffdshow.

ReClock works well for me, though, for this purpose and in fact the function was added to ReClock specifically to address your situation.

[diizzy]

Unfortunately this doesnt seem to work, even if I set 2/0/0 I get multichannel PCM. The link provided by mrcorbo appears to be that I'm looking for. Unfortunately Im not a developer myself so I cant add it :-/

Albain's trick is for creating the surround effect inside ffdshow, then output the multichannel PCM to the receiver as always but only for stereo sources and leaving 5.1 streams untouched. You can even create your personal matrix for the mix, so the possibilities are endless.

[JarrettH]

Do you think there'll be a new beta soon? :confused:

[_xxl]

Maybe a bug ?
Since Version 3040 when resizing SD material to e.g. 720p, picture seems to be zoomed (only a part of the picture is resized to full screen resolution). When unchecking and checking resize checkbox, everything works like a charm. When opening a new video, trouble starts again. Version 3029 works flawlessly.
OSD always shows correct in- and output resolutions.
Is 3031 the cause for that regression? If nobody is going to fix I will revert it.

[albain]

yes but clsid added a workaround since, I don't know if that fixed all the problems though

[clsid]

My workaround was only for a limitation of the Overlay Mixer. It does not fix the reported cropping and resizing issues.

I think it may be best to revert 3031, until a better patch is made that also deals properly with the filters of ffdshow.

EDIT: Last (tested) working version is 3054, first (tested) broken 3058

[albain]

It may be my modifs then (rev 3056) but I don't understand why it would work on x86 and not on x64 ??
The modifications I brought is to check if the output filter (audio renderer) will accept the media type in case of format change. This does not apply to your case but the other svn modifications concern x264 and ffmpeg updates.

Could you report the debugview traces when launching this file from mpc-hc 64 ?
You will have to set the allowDPRINTF registry key to 1 in FFDShow *64* registry key.

Test number 2 : could you install ffdshow 3054 64 bits, make a copy of libavcodec.dll and then install a non working version of ffdshow (3058 for example) and overwrite libavcodec.dll by the rev3054 one ?

Thanks

The libavcodec.dll (3063 replaced with 3054) trick has no result = no changes and I can't find the allowDPRINTF key I even did a full registry search for allowDPRINTF It should be the same path for the x86 version on a x86 windows so if you can be more precisely (HKLM\Software\GNU ? HKCU\Software\GNU ? or ?)

EDIT: Replacing the ffdshow.ax with the old one (3054) does the trick = ffd it's connectable (working)

Replacing the file does not change anything. The same problem exists with the ffdshow x86 icl10 3056-3063.

Only ICL10 version? Is 3055 working?

[Mercury_22]

Ok I've solved the allowDPRINTF key "mystery" first it has to be created by checking the "Output strings to debugger" but I have no log file (maybe because FFD audio it's not connecting )where should it be? C:\Program Files\ffdshow ? or C:\ ? or...?

EDIT: ICL11 rev 3063 it's working ! http://www.mediafire.com/?sharekey=3f33c77c2cf9ce251686155677bb26855284166a6fc12f6c

[Daedalus01]

hi, i was wondering if you guys could help me out on a very irritating issue?

i love ffdshow's audio decoder and its ability to normalise / normalize ! it makes the dialogue easier to hear at a volume such that loud sounds dont deafen me!

however, i am having trouble with it when re-encoding a 5.1 source to ac3 5.1 and passing via spdif optical. The normalisation will work but after a while (5-10min, or i think when a scene changes) it will stop working. if i seek to a different part of the video file it works again.

i am using the latest ffdshow.

does anyone know why?

thanks!

Anyone know how to make the "grab" feature grab all frames that are output from the yadif de-interlacer in double framerate mode

ie grab double the amount of frames as would normally be grabbed.

At the moment it currently skips every second frame output from yadif. Its like the grab is being triggered from something in the chain that hasn't got the double frame rate, perhaps as the frames are decoded grab gets triggered?

Hopefully someone can update this to make grab be triggered from whatever was before it in the chain, either yadif, avisynth, whatever... as they can possibly change frame rate.

[yesgrey]

Have you tryed with an avisynth script using ImageWriter function?

[mark0077]

Nope, I could but just wanted to point this out to ffdshow developers as a potential issue with grab. Also grabbing to BMP doesn't give a clear indication as to what type of YV12 -> RGB conversion is done for example. I am hoping its using my RGB Conversion settings, ie high quality, dithering on, assume full range output, limited range input etc.

this bug also happens on DVD MPEG2, as GinSonic said: http://forum.doom9.org/showpost.php?p=1312403&postcount=7785

each time I wanna open a DVD, I have to disable resizing in ffdshow, then reenable it once the movie is playing...otherwise HR crashes MPC, and EVR/VMR9 zoom the picture to death :o

would an option be added to audio decoder, "delay" filter, so that all channels are controlled by single entry box? something like an extra entry row with checkbox that will grey out individual channels

[Mark_A_W]

Is is possible to create a shortcut to the offline configuration properties for the Audio Processor filter?

Out of the box ffdshow has shortcuts for the Video Decoder and Audio Decoder.

[FoLLgoTT]

Can anyone confirm that when outputting LPCM directly from the gabest splitter (or MPC-HC) the right rear channel gets a wrong/defect signal? With TrueHD everything is fine.

It seems to be no problem when the decoder of MPC-HC decodes anything to LPCM and FFDSHOW outputs to the renderer. In this case the signal of the right rear channel is correct. A good Blu-ray to test is "300", because it has LPCM, TrueHD and AC3 audio tracks.

[anyone23]

Somehow the auto deinterlacing of ffdshow doesn't work here for a few TV channels.

Example: http://www.file-upload.eu/download-1866342/ffdshow_auto_deinterlacing.m2v.html

Open the file in DGIndex and analyze it. After about 14 seconds, the frames are flagged as progressive but they are in fact interlaced.

The Cyberlink MPEG-2 Codec plays the file flawless and on the televisor the deinterlacing works too.

My ffdshow settings: http://www.pic-upload.de/view-3000528/ffdshow_deinterl.png.html

Catalyst settings: Vector adaptive deinterlacing without pulldown detection, ATI HD 4870 PCIE, Catalyst 9.8.

This happens with all the interlaced content of this TV channel.

Is this a bug of ffdshow?

[thewebchat]

I would like to point out a bug about mod4 width video being sent from ffdshow to intermediary filters before the renderer:

Enable the "Process frames flagged as progressive" option.

[SledgeHammer_999]

I want to report a bug of ffdshow with subs. Just create a mkv file with this track layout:

[anyone23]

@anyone23
Enable the "Process frames flagged as progressive" option.
You mean "Methods: Bob"?

Yeah, but with that option everything gets deinterlaced even content correctly flagged as progressive.

Isn't there a way to make hardware deinterlacing like in Cyberlink (PowerDVD) Decoder because here the auto option works?

[STaRGaZeR]

You mean "Methods: Bob"?

Yeah, but with that option everything gets deinterlaced even content correctly flagged as progressive.

Isn't there a way to make hardware deinterlacing like in Cyberlink (PowerDVD) Decoder because here the auto option works?

No, because Haruhiko (developer) specifically designed it that way. It's the channel responsability to flag the content as they should. I was against this decision precisely because of DVB issues, but I understand his position. You can create a profile with "Process frames flagged as progressive" option checked and set autoload conditions for this kind of streams.

You should put the subtitles last. Older versions of MPC also do not like subs as the first track.

[SledgeHammer_999]

You should put the subtitles last. Older versions of MPC also do not like subs as the first track.

Well it is still a bug of ffdshow. I don't think there's an explicit guideline for subtitle tracks being last. It's just a convention. Furthermore if I enable the internal subtitle renderer in MPC the subs are detected.

MPC = 6.4.9.1(rev 104)

[clsid]

Yes, it is a bug that should be fixed. I just wanted to say that triggering it can be avoided.
