The MPEG-TS splitter doesn't show audio track languages when you load a Blu-ray playlist.

How can I disable MPC-HC internal WM ASF Reader, and use system default Windows Media Source?
I have serious problem on playing WMV (ASF) format.
Pause/resume and seek deranged and sometime process hang up.
Now my splitters are disabling NEW WM ASF and using DMO.

Be fair, Piyoko was talking about win xp and you are using vista as far as i remember. Maybe that's the difference - try Win7.

there are some problems with frame-based subtitles after version r1312 (the next version on xvidvideo.ru is r1323, so i can't pinpoint the exact regression-point between r1312 and r1323). even with DXVA i get up to 40% CPU usage on a dual-core with long subtitle lines, when with r1312 i dont get more than 8% CPU usage on the same movie.

There is a small problem with the building ...

Hey guys I am wondering if you can help me troubleshoot a little problem.

I am watching DVB-T recordings with the Microsoft Decoder but they don't seem to deinterlace. I'm using EVR-CP on Vista, what settings should I change in order to get deinterlacing to work?

You have to reset your settings to defaults by deleting the registry key (see the troubleshooting guide in my signature.)

The reason this is happening is because after this update mpc-hc cannot find the "disable subtitle animation" key and is enabling the animation, which takes a lot of cpu cycles to calculate.

tetsuo55, Any chance someone could say to the cognoscenti what we need to change to edit the registry. Resetting the registry when you have a lot of custom settings is likely to be a lot more hassle than adding or removing a few keys.

I agree resetting the registry is a good troubleshooting step when all else fails, but I hope it should not be needed in this well understood case.

Good idea.

I suggest making a wiki page like this one: http://xbmc.org/wiki/?title=Advancedsettings.xml

We could explain each setting based on their entry in the .ini file (and provide the registry path it would use if it was in the registry in each section)
I don't have anyone available for this right now, so i would like to ask the community to make the basic list itself and fill whatever you know, then i can ask the dev's to fill in any unknowns.

This page is also a good start for the settings cleanup that is planned in the far future.

EDIT:

Also it would be interesting to know which default settings you change and why.(apart from external filter use)

Has there been any progress with regard to solving the slow loading bug that people are experiencing on Windows 7 when using EVR CP? Some people are getting delays up to 30 seconds.

Also, allowing animated subs should not have a negative performance effect on static subtitles, such as SRT or VobSub. Seems to me that there is a bug somewhere. A noticed that there is a ToDo comment in a function called IsAnimated() in the code. Maybe that's related?

These kind of bugs should be given top priority.

checking the "disable animation for slow computers" indeed lowers the CPU usage, but i don't get it: what has normal text-only frame-based .sub file in common with karaoke/animated .ass subtitles?

i always have the "disable animation" unchecked, as my CPU can handle any karaoke sub i stumbled upon. so even with enabled animation r1312 doesn't show the problems that revisions after have. clsid seems to have the same opinion :P

just create a .sub file with a long line , drag&drop it over a movie, and in my case at and after 1min16sec the CPU goes to 50%

Code:
{1}{1}23.976
{1}{45000}qwertyuiop asdfghjkl zxcvbnm QWERTYUIOP ASDFGHJKL ZXCVBNM qwertyuiop ASDFGHJKL

It was reported on another forum that "BT.601 -> BT.709" shader uses slightly wrong coefficients.
Current shader:
Code:
    // RGB [16,235] to YUV: 601 mode (128 is not added to Cb and Cr) 
    float y=0.299*c0[0] + 0.587*c0[1] + 0.114*c0[2]; 
    float Cb=-0.172*c0[0] -0.339*c0[1] +0.511*c0[2]; 
    float Cr=0.511*c0[0] -0.428*c0[1] -0.083*c0[2]; 
  
    // YUV to RGB [16,235]: 709 mode (Cb and Cr are 128 less) 
    float r=y+1.540*Cr; 
    float g=y-0.459*Cr-0.183*Cb; 
    float b=y+1.816*Cb;
Recalculated coefficients:
Code:
    // RGB to YUV: 601 mode 
    float y=0.299*c0[0] + 0.587*c0[1] + 0.114*c0[2]; 
    float Pb=-0.168736*c0[0] -0.331264*c0[1] +0.5*c0[2]; 
    float Pr=0.5*c0[0] -0.418687589*c0[1] -0.081312411*c0[2]; 
  
    // YUV to RGB: 709 mode 
    float r=y+1.5748*Pr; 
    float g=y-0.468124273*Pr-0.187324273*Pb; 
    float b=y+1.8556*Pb;
As I understand, original comments (// RGB [16,235] ...) have nothing to do with shader code, because we are working with range [0, 1] (E'R E'G E'B) where differences between [16-235] and [0-255] have been already corrected.
Besides we can use simpler formulas:
Code:
Y = Kr*R + Kg*G + Kb*B
V = (R-Y)/(1-Kr)
U = (B-Y)/(1-Kb)

R = Y + V*(1-Kr)
G = Y - U*(1-Kb)*Kb/Kg - V*(1-Kr)*Kr/Kg
B = Y + U*(1-Kb)
Also in "0-255 -> 16-235" shader 13-25 lines should be removed. They are just a copy of 0-12.

WTV Support

Feature Request

WTV files are produced by Win7 media center. MS has a dev page for Consumption of a WTV file in DirectShow which includes sample code.

The format allows dynamic changing of content codecs, which would require graph rebuilding (another important feature imho.) I don't think the video would change as yet, but audio changes from AC3 to stereo in commercials. This could be incorporated in the redesign of the audio subsystem.

DTB has prelim support for WTV, and some users at greenbutton are trying to switch from mkv to wtv.

This format will become more prevalent with the adoption of Windows 7.

None of the dev's can reproduce this issue so its not being worked on.

The animation system is designed in such a way that it causes a huge overhead over subtitles, regardless of actually animating or not. When it actually does have to animate the system requirements rise even further.
Fixing this requires a complete refactoring of the subtitle renderer

At this time there are no developers working on mpc-hc that can fix either bug

At the same point were the state of the option to enable/disable animation is checked (to determine which code path to take), can't there be an additional check to see if the current subtitle format is actually a (possibly) animated one or one that is always static?

Have anyone done any comparisons between current builds and old builds (1047 or earlier) to see if there is any difference in CPU usage with animation enabled?

Perhaps Casimir/ar-jar/Beliyaal could do a general code review of the whole EVR CP code? That might reveal some parts of the code that are buggy.

that seems to be technically impossible within the current framework

Beliyaal optmised as much as he possible could. he thinks there is still room for a few % improvement.

They have been doing nothing else for the past year

I get this error with build 1333 x64 running on Win 7.



I open the Goto window and even when I just let it sit at the pre-entered values the error pops up. Entering values manually gives the same error.

Only thing that works is entering a single number that gets interpreted as miliseconds.

Any ideas regarding this? If necessary I can check with what build this error started happening for me.
