There is a problem since version 2787

Revision 2786 is fine
Revision 2790 is not. It corresponds to an update of libmplayer

Problem : ffdshow crashes in Media Center
I have checked, this problem is different from the one I saw earlier.

The crash is located here :

Twscale.cpp

void Tswscale::done(void)
{
if (swsc) libmplayer->sws_freeContext(swsc);swsc=NULL;
}

and the message of VS is "This may be due to a corruption of the heap".

I have no idea of how to analyze it

Thank you for any help

I don't mean using the DScaler deinterlacing filters in ffdshow.
I mean using ffdshow as a filter in DScaler, to postprocess the picture in DScaler.

Was able to do it in some version of ffdshow way back.
Works for me. Please update to the latest.
I'm writing about preset settings (http://ffdshow-tryout.sourceforge.net/wiki/preset_settings). Does it help? You need a preset settings named ffdscaler.

Unfortunately, I have compilation errors on builds 2788 and 2789, so I have to stick to 2790

By the way, in a dialog 'About' page, if I click 'Version details", I see
"ff_theora.dll not found".
It's much appreciated if you implement a missing function 'getVersion'.

And if you have more time, please update ff_theora. The original project
is great, however, our ff_theora is quite outdated.

Please forgive me, but as mentioned earlier this week it's my first time using a compiler, so I will probably not “implement” anything related to theora as I do not know where/how to create this missing “getVersion”.

However, I will soon post a big translation patch.

Exactly when does ffdshow crash in MC? During decoding or only when using as a post-processor? Are specific settings required? Then I'll see if I can reproduce it on Vista x64 MC. Have you been able to reproduce the crash outside of MC?

In 2788 I have cleaned up the config.h file, removing malloc and free defines. Same functions are defined in mem.c/h and those are now used instead. Only difference is their names: av_free, av_malloc. Maybe a wrong name is still being used somewhere in the code. See if adding the two defines back to config.h solves the crash.

edit: I have spotted a few uses of malloc in yuv2rgb.c. I will replace them with av_malloc. That might fix it.

OK, never mind.
However, it's a small function. There are many similar "getVersion" in other dlls. If you are interested in C/C++, it's a good place to start. :)

And good news, translations are welcome.

Crashes occur when browsing into the video folders : the decoders are loaded to display the thumbnails for each video.

Otherwise if I play the video with wmp it works fine.

I will test your fixes when available

How did you name the subtitle files? If ffdshow doesn't find them, it can't display them. You can also load a subtitle file manually in ffdshow settings if needed.

No there isn't problem with subtitle file (.srt) because ffdshow can display them if I don't use opendvd function of MPc homecinema.
Subtitle can't be displayed by ffdshow only if I use opendvd function in mpc-homecinema (function to see dvd movie).
Even manually it doens't work if I use open dvd function of mpc homecinema.
To see subtitle I must not use opendvd function and load manually .vob file.

subtitle file

dvd sample
http://www.zshare.net/info.html?57839553-f44f5747969ad8972a800c653aafc20f

subtitle file doesn't belong to this dvd but It allow to show the problem.
If I use opendvd function to open dvd and load subtitle function of Mpc homecinema subtitle are displayed. But If i use subtile function of ffdshow instead of load subtitle function of mpc homecinema subtitles are not displayed.

I don't think this has anything to do with how MPC operates. It is more likely related to the "DVD Navigator" source filter. For example the DirectVobSub subtitle filter only loads when a compatible source filter is in the graph. I suspect something similar applies to ffdshow. Autoloading the correct subtitle file is certainly not going to work when playing a DVD, because when ffdshow asks the source filter for the filename it will just get an empty string (unlike when you play a separate .vob file). So you would have to manually specify the sub file in ffdshow configuration. Although that does not seem to work with DVDs either.

I suggest you use the internal subtitle renderer of MPC instead for manually loading the external subs with DVDs. Or wait for Haruhiko to comment on this.

Do you also get an "Integer division by zero" error in MPC when seeking in your sample DVD?

I found a problem with ffdshow and MPC HOMEcinema

If I want to see DVD movie with separated subtitles (which doesn't on the dvd), subtitle aren't display if I use open dvd fuinction of MPC Homecinema and subtitle function of FFDSHOW.
I use mpc homecinema 1018 and ffdshow 2812
I have re-enabled external subtitles file for DVD. I disabled for a reason, DVDs may have DVD subtitles and closed caption. If three kind of subtitles are displayed at the same time, it's just a mess. And this really happens (strictly speaking, external subtitles are not displayed at the same time as DVD subtitles, but if DVD subtitles disappear, external subtitles appear immediately...), ffdshow just does not crash.

ffdshow is not a source filter, it therefore does not handle file formats. ffdshow can not be used to play your file.

I use ICL for compiling a couple of files (libmad, libfaad, libdts, etc)
is that also the case for the xvidvideo.ru builds?
and why do the latest builds from there check "reset all ffdshow settings" by default ?!
they also check "decode h264"....that wasn't the case w/ last week packages :o

and sometimes when I want to open IE6, I have to close MPC or it won't open...apparently the winamp2 plugin in ffdshow audio is blocking it from popping up :confused:

You would have to ask the maker of the xvidvideo.ru builds.
Reset settings is only done on the initial installation, not during upgrades. During the initial installation, the installer does not care about any existing settings, it will use the defaults that we have chosen. No settings are changed during upgrades.

Does not work either. ffdshow will simply fail to load when ffmpeg-mt is selected for H.264. So I suspect a problem with the pthreads dependency.

30th March 2009, 18:02

Eragon4ever, thanks for offering your help, but now it's fine. Here is a recap of the story:
1) On the tracker item, I provided a .patch file (28th March). haruhiko_yamagata told me it wasn't possible to apply it, so I deleted it.
2) On the tracker item, I provided a different .patch file enclosed in a .zip file (30th March). haruhiko_yamagata applyed it on rev 2836. Unfortunatly, it broke the encoding of one file.
3) I provided the broken file separatly, and it was fixed on rev 2843.
I tried to commit even before haruhiko_yamagata and noticed the probelm with the patch but I was in a hurry and not sure if it was a problem on my side, so I didn't post about it. By the time I was back, he already made his post...

An interesting bug detected a week or so ago.
Tried this on several latest revisions of ffdshow.

30mb m2ts sample:
http://www.mediafire.com/?mwfm4jj2zmm

Works superb. Plays well by both beliyaals and SVN MPCHC versions.

Unless I do the following:

Splitter -- Haali splitter (latest beta).
Player -- MPC-HC.
Video decoder -- MPC MPEG2 internal. (doesn't really matter here)
AAC Decoder -- ffdshow.

Each time this sample is played ffdshow looses audio after several seconds. If I use internal MPC AAC decoder then everything seems working as usual.

Replicated this problem with both x86 and x64 versions (i.e. both Haali splitter and ffdshow).

Then I even tried building a graph (to exclude potential interference from MPCHC) and was able to reproduce the bug as well.

So here there's a bug for sure, not quite certain yet whenever it is Haali's fault or ffdshow ;)

In ffdshow 2844 x64 (http://www.xvidvideo.ru/content/view/693/1/), ffmpeg-mt works great! Neither any problems with the building I did not have.

The absolute values of the coeffs for one output channel need to sum to 1, otherwise there may be clipping. Check the normalize matrix, it does just that even if the coeffs do not change in the window.

indeed, I've added a VST vu-meter and on my loudest 24/96 5.1 tracks, I have to lower the volume to 45% in ffdshow prior to the matrix to avoid clipping > -0.1dB

I'd like to take it in account directly in the Logic 7 matrix, but w/ the inverted phases and stuff I've got no idea how to do so :o
