ffdshow tryouts project: Discussion & Development

[Thunderbolt8]

another sample from another AVC remux, same problem:

http://www.sendspace.com/file/q3rvfp
could anyone please have a look at these? I really would like to know if this is maybe due to mkvmerge then I know Ill have to wait until a better remux solution comes up.

[clsid]

Well, ffdshow should show the actual name of the DMO filter, instead of the wrapper filter. So that is another little bug. Same probably happens with the ACM and VFW wrappers.

As for splighost.mkv, whichever I use CoreAVC or ffdshow, I have the same problem.

[haruhiko_yamagata]

I've made 2 profiles in ffdshow audio...one for movies and one for music.
but for WMV files, it never works.
the "movie" profile is supposed to be enabled when "ffdshow video decoder" is active(I've set ffdshow video to "all supported"), but it doesn't work for WMV files......even though "ffdshow video decoder" is loaded ?!ffdshow video decoder has to be loaded before ffdshow audio initialize its preset settings. Wmv splitter loads audio first.

still not a foul proof solution, because the "movies" profile is loaded for .wma files :scared:

ffdshow video decoder has to be loaded before ffdshow audio initialize its preset settings. Wmv splitter loads audio first.
So that also means that the preset condition won't work for any filter that appears after ffdshow in the graph? Like for example "Video Renderer".

try to remux the clipboy.m2ts also to .mkv please, then you should see the same problems there. I gave you this one as .m2ts so you could have a look at the original structure.
so coming back to my initial question, are all the H264 features of those 2 movies are included in ffdshow meanwhile? if yes, then I can take it for granted its mkvmerge that causes these problems?

[skrowl]

Has a few issues playing (legally obtained, of course) EVO files. The video looks perfect, but the audio comes out garbled.

[Leak]

I've tried foobar, but the GUI sucks
Have you tried it lately? The GUI was completely revamped for it's 0.9.5 release, and even before that there were several other GUI plugins to replace the default one...

np: Pan Sonic - Lähetys / Transmission (Katodivaihe / Cathodephase)

[haruhiko_yamagata]

So that also means that the preset condition won't work for any filter that appears after ffdshow in the graph? Like for example "Video Renderer".It should work for video decoder because ffdshow is connected to downstream when it is initialized. It may or may not work for audio decoder.

[Inventive Software]

This is most likely because you don't have an E-AC3, TrueHD, DTS-HD MA or DTS-HD HR decoder, depending on what audio type it is. If you want E-AC3 support (or the other HD audio formats), bug the ffmpeg devs, not us! ;)

How complete is the ASS subtitle support? It seems to work fine most of the time, but vertical writing seems broken (unimplemented?) at least in a few anime op/ed sequences with karaoke kanji/kana.

e: Forgot to mention rev 1850

[DigitalDeviant]

I'd also like to add it doesn't make use of mkv's attached fonts like vsfilter does (I haven't tried to actually embed the font data in the ass file itself yet).

Works ok with Haali splitter. "Load embedded fonts" may need to be set in Haali's options. While testing, I had that setting disabled and I got subs with Arial font. Intended font showed up when enabling the setting. On subsequent tries with setting disabled right font was still used (fonts cached somewhere?).

Friend from IRC was asking...

<+Jenova266> Just wondering if it would be possible to add a simple tick box to the deinterlacing filter page which would run the frame doubler filter before the selected filter and if so please do so, Thanks in advance

TODO (ASS related, if my motivation continues)

complete karaoke (fix a bug) - done
implement move
implement layer
implement collisions
implement clip
implement other minor stuffs (scrolling text, rotate/transformation, drawings, vertical writings and others)
check and fix compatibility issues
support style overrides from GUI

"Just wondering if it would be possible to add a simple tick box to the deinterlacing filter page which would run the frame doubler filter before the selected filter and if so please do so, Thanks in advance"
Considering that the frame doubler needs, if anything, progressive frames I really wonder what he hopes to achieve by that?

Also, proper full-rate deinterlacing is done by the bob filters already...

[Thunderbolt8]

btw. whats the reason that interlaced vc-1 content is not supported yet, do you have to wait for the ffmpeg guys to implement it or do you need more samples?

Dear ffdshow developers, please, take look @ this thread (http://forum.doom9.org/showthread.php?p=1103680). Maybe it's ffdshow problem? Or maybe it's possible to add some workaround into ffdshow (at least - complete lock flip option via yet another option)

[nekrosoft13]

could someone let me know if ffdshow can handle EAC3? also know as DD+

[clsid]

EAC3 is not supported yet. It is unknown when or if it will be supported in the future.

[dimzon]

talking about my problem (http://forum.doom9.org/showthread.php?p=1103680) seems like this is ffdshow issue (read this (http://forum.team-mediaportal.com/codecs-external-players-55/strange-flip-behavior-using-ffdshow-35689/#post237734))

Dear developers, can you add some logging feature to understand what happens? Thanks.

[dimzon]

maybe MediaPortal broadcast some magic WM_XXX message for it's own needs every time playback started and independend message with same code are in ffdshow (occurs message number collision)?

Anyway I need some assistance from ffdshow developers

[nekrosoft13]

EAC3 is not supported yet. It is unknown when or if it will be supported in the future.

thanks for responce

[nautilus7]

Thanks for graphedit bug fix.

[leeperry]

any chance seeing the winamp2 plugin bugs fixed ? :cool:

basically it doesn't seem to be closed properly, so you can't open 2 files in a row, it crashes the player(mplayerc.exe and mplayer2.exe).

but if you click on "CONFIGURE" in the winamp2 section of ffdshow audio, then it works....but after 3 files in a row it's using 70% of CPU time on my 3Ghz C2D :(

problem is easy to reproduce with this plugin :
http://www.winamp.com/plugins/details/79374

if you could also offer the option to hide the plugin GUI(like winamp does), that would be supreme coolness :p

use the sonic audio decoder.

[clsid]

Please stop repeating your requests over and over again. It won't make a fix appear faster. Its just plain annoying.

Haruhiko already said that he will have a look at it when he has time.

[leeperry]

sorry, didn't mean to be annoying..

just wanted to give a clearer explanation in a few words, that's all.

:thanks:

[Inventive Software]

Since your requests seem only to be with this one particular plugin, have you tried with other DSP plugins? ;)

[leeperry]

I did.

[dustobub]

Has anyone noticed that the XXL builds with the cabac patch have broken libavcodec's VC1 support. Video does play, but has significant artifacting and can lead to a program crash. Any idea's, or should I be asking over at FFMpeg. Thanks.

Dustin

[dustobub]

FFMpeg devs now are aware of the bug. It looks like it was introduced around build 1858.

[_xxl]

That patch has nothing to do with VC-1.

[dustobub]

You are correct, the timing of the bug however made me think it was the cabac patch, my bad.

[Jeremy Duncan]

Is the libmpeg codec updated each time libavcodec is updated?

I look at the svn and I see all these updates for libavcodec, and Iwonder about this.

Also, can somebody tell me if the newer ffdshow is faster when comparing the libmpeg codec to previous versions of ffdshow?

use the sonic audio decoder.

Problme is :

Sonic Decoder applies a ugly Mix of DynamicRangeCompression+DialogNorma.+gain

The Decoder System Settings have no Effect.

Nero AudioDecoder2 applies DRC+DialNorm too

So we have no Decoder fro Realtime with the ability to disable DRC/DialNorm = bad

So lot of People are waitng for a ffdshow with EAC3/THD support

[fastplayer]

Is the libmpeg codec updated each time libavcodec is updated?
No, different projects.
libmpeg2 development was finished years ago. From time to time minor bugfixes keep trickling in though.

[Thunderbolt8]

I have a problem with a H.264 broadcast here with ffdshow (1870 xxl), the picture is pretty much distorted, while its fine with CoreAVC and VLC (0.8.6d).

I made a short sample: http://www.sendspace.com/file/rk4epu

[fastplayer]

Clip plays fine here with rev1868.

[clsid]

Fine too with 1872.

[Thunderbolt8]

tested it with 1868 clsid, but strangely for me it looks the same as before, like this: http://www.sendspace.com/file/tixf46

what could be the reason for that??

[dustobub]

FFMpeg devs now are aware of the bug. It looks like it was introduced around build 1858.

I know this is more of an FFMpeg issue, but here is a link to a 1080p VC1 sample if you are curious.

[dustobub]

The VC1 bug looks like it was fixed last night. Build 1873 fixes it.

[ImAhNoBoDy]

I recently ripped subtitles from a Japanese DVD using VSRip. There are 4 different languages in the idx/sub file. The default sub is in Japanese but when I try to choose English, WMP crashes all the time. The sub loads by itself cause it has the same filename, but when I manually choose the subtitle myself, I am able to choose English. I mux the subs in mkv and it works just fine. Vobsob from VSfilter works just fine too when I enable it (I mostly use ffdshow to display subs).

Now I have tested other idx/sub files that has multiple languages and they are just fine. I have a sample: http://www.sendspace.com/file/inqfew

[foxyshadis]

What splitter do you use?

[Thunderbolt8]

the haali splitter & haali renderer. I already tried it with mpcs internal splitter and also with overlay mixer and VMR9 as well, but the result stays the same.

The VC1 bug looks like it was fixed last night. Build 1873 fixes it.
before im going to post on this as well, could this be a bug with funny blue like colours, which appear then and when?

[leeperry]

hey guys,

simple question if you don't mind.

I was told by Seb.26 that checking the "high quality YV12 to RGB conversion" was actually converting to YUY2 then to RGB ?!

atm I'm decoding h264 with ffdshow from xxl_, then upscaling in lanczos 4X and sometimes deinterlacing.

is there any point to output from ffdshow in YUY2 over YV12 ?

I then send it to EVR with MPC HC, use some PS scripts in MPC HC, and either EVR or my ATi drivers are doing the RGB32 conversion in hardware.

I've made some screenshots, the CRC is different but I can't see any difference between YV12 and YUY2 with h264 decoded by ffdshow ?! :eek:

TIA,

[haruhiko_yamagata]

If you don't see any difference, there's no point.
Implementation of YV12 by the downstream filter may be buggy. YUY2 output is useful only in such cases.
Another use of YUY2 output is MJPEG. Most MJPEG files are decoded to YUY2 (strictly speaking, 422P).
If you use text subtitles, RGB output make sense.
