@alexins: Yes, I know. I created a patch to revert this change because I'm using komisar's MinGW for the 64bit version. Everything is fine now.

PS. If you read some posts before, you'll see that Mercury_22 is not the only one who's having issues with ICL 11.1.038 builds while 11.0.072 works as expected. Maybe you should change your ICL version to 11.0.072. (If you don't have it, send me a PM).

I use this version:
http://sourceforge.net/projects/ming...1.zip/download
Using latest builds I can't compile pthreads for win64.

I don't know if this could help, but have you tryed using the "WMV PowerToy"?
It's a little program that lets you set some parameters in Microsoft's WMV encoder and decoder.
You can get it here.

Pthreads-w32 (CVS code) + w64sup.patch = Successful build!

_xxl · 16th September 2009, 12:39

I have updated pthreads to latest 2.9.0 + all patches for win64 and other bugs. I can't compile pthreads with latest MinGw64. They are broken.

… strange… in me build is passed without the problems,...

Code:

make CROSS=x86_64-w64-mingw32- clean GC-static
make CROSS=x86_64-w64-mingw32- clean GC-inlined

... truth I do not use assemblies of mingw-w64. I use my constructions of mingw gcc x86/x64, for these constructions I took scripts written Komisar and introduced in them my changes.

Does this apply to MPC-HC too? the 64bit build has many bugs that are not in the 32bit build, mostly related to libavcodec.

Maybe you could share exactly how you made your build environment, i think many will want to install it like you do (i know i do)

That is my problem with latest MinGW64.

Try like this:

Code:

make CROSS=i686-w64-mingw32- clean GC-static

No, this does not affect the mpc-hc …

In the next few days, I will try to post for download scripts (build components mingw), and issue the finished building based on gcc 4.4.2 (prerelease) and GCC 4.5.0 (experimental).

I have all versions of ICL 11.*.*. I'm still going to monitor the situation, it is necessary to gather more information for decision.

petran79 · 17th September 2009, 13:55

There is a problem with the new version of DFX audio plugin for Winamp and ffdshow audio.It does not appear on the ffdshow Winamp plugin panel. Up to version 9.100 there was no problem. Other plugins appear and work normally.

Players like KMplayer and GOMplayer accept the new version

leeperry · 18th September 2009, 22:15

is there ANY way to get sharper subs in ffdshow?

I understand blurry subs prolly look great on LCD screens, but on CRT/DLP all these font smoothing algorithms look terribly ugly(curse you Windows Vista/7!

)...is there a chance someone could add a "blurriness" slider please? or am I missing something? everyone's watching blurry subs in here?

this is terrible w/ a projector, it's blurry-land..

clsid · 18th September 2009, 22:28

First of all, I don't think that there is a developer available at this moment that is able/willing to implement this kind of suggestions.

Secondly, you are asking for something that is the exact opposite of what you want to accomplish.

Thirdly, use DirectVobSub (or MPC internal) and increase the texture resolution setting. That will give sharper subs.

leeperry · 18th September 2009, 23:45

well, I meant a blurriness slider....so I could set it to 0

I guess it's great to have blurry fonts on LCD...but luckily, many ppl don't use this technology. yeah, I guess I'll have to wait for madshi to add a subs pin in mVR...KMP is able to give very sharp subs, but it can't be used at this point

DirectVobSub is terrible...most of the times you can't even change the vertical alignment, you can't even override the look of .ass subs.

ah well, time to brush up my Japanese I guess

Astrophizz · 19th September 2009, 00:32

You could try having the subs render after upscaling. Also so far as I know Vista/7 use the same font smoothing as XP and this font smoothing has no effect on subtitle rendering.

leeperry · 19th September 2009, 01:22

I don't upscale...this is downscaled from 1080p in ffdshow then subs are added on the native res, and the subs are always blurry ...and I've tried every possible setting, the anti-aliasing seems rather high...and I'm not the only one finding them blurry

well, Vista/7 seem to enforce that Cleartype stuff, w/ a bit of a hassle you can disable it in explorer...but not in other apps? ah well, if mVR finally delivers I'll stay in XP until the end of days...I don't need blurry fonts in all my apps, nor 40 mandatory background services or an OS that decides what I'm allowed to do: http://www.cs.auckland.ac.nz/~pgut00...ista_cost.html

anyway, case closed...I understand blurry fonts will take over the world someday, I'll just wait for mVR to support subs.

Astrophizz · 19th September 2009, 07:10

Yeah I find the fonts blurry from VSFilter compared to the KMP or MPC-HC internal sub renderers. I wish something was done about it but I put up with it and I guess I've gotten used to it. I'm almost certain that it's totally unrelated to Cleartype though.

VSFilter renders directly to the decoded frames so it's limited by video frame's resolution and YV12 colorspace.

Astrophizz · 19th September 2009, 11:21

Doesn't the subtitle renderer in ffdshow have the same restrictions as VSFilter unless the scaling is done internally? Though I suppose since leeperry scales before adding the subtitles my issue isn't the same as his.

no it's not, these are two separate issues.
if you enable 2x/3x anti-aliasing for subs rendering in KMP, you also get blurry fonts. that's prolly what is happening in all these ffdshow/mpc/dvobsub..but they don't allow you to disable AA. anyway, this most likely will never be fixed...it's by design.

thewebchat · 19th September 2009, 17:29

VSFilter process:

1) Get subtitles
2) Create subpicture that is 64x the resolution of the video frame
3) Scale subtitle sizes using some magic numbers
4) Multiply everything by 8
5) Get outlines and composite (note that there is no ClearType going on here)
6) Downscale to video resolution and paint

Note that the combination of 2 and 4 is the reason that VSFilter supports 8th-pel subpixel positioning and sizes.
