Media Player Classic Home Cinema (MPC-HC) - DXVA!

Thanks a lot!

Not sure to understand your question. CCC DR works with MPC-HC decoder because I tried it and things change from 16-235 to 0-255.

I don't know if it is possible to use AVIVO instead of video renderer to control levels. I still haven't understood the relationship between video renderer and video card, probably the renderer developers on this forum (beliyaal, ar-jar, madshi) have a clear vison of that.

As for PDVD9, I don't know it enough.

If
1) you set DR to 16-235 to instruct ATI to expand 16-235 to 0-255
2) use EVR and enable DXVA in MPC

Do you still see banding?

1) According to the tests I did yesterday (but I'm going to test it more thoroughly in the weekend), with my ATI HD5750, setting DR to 16-235 compress levels: 0 becomes 16, 1 becomes 17, 2 becomes 18 and so on; and there is banding;

2) there is banding.

I find a problem with subtitles. Some subtitles are cut in fullscreen


In windowed mode subtitles are displayed

I see no problem.

hey thank you guys... both of you

A longer explanation (maybe can be useful for others too):

The decoding process is actually made up of several phases:

- Reverse Entropy
- IDCT (Inverse Discrete Cosine Transform)
- MoComp (Motion Compensation)
- Deblocking

A video card can support DXVA for one or more of the phases. You can see which using DXVA Checker. The name of the mode indicates which phase is supported. VLD (Variable Length Decoder) means the decoding process is supported as a whole: alla phases are supported, a mode known also as bitstream.

You video card (as any recent ATI) supports VLD mode for H.264 and VC1, but not for MPEG2, where only IDCT is supported.

Commercial players (like TMT, PDVD, etc...) support IDCT DXVA and thus you have DXVA with them. MPC-HC supports only bitstream (VLD) and thus you have DXVA for H.264 and VC1 only, not for MPEG2.

This is not considered a big problem, though, becuase MPEG2 decoding in software is generally not a big burden for modern CPU.

and this is very well explained... very nice.

as I said, my question was out of interest as I'm not into video stuff that much anymore but at least was curious why I couldn't "solve this little problem". As mentioned above, I wasn't aware of it.

Guys, I really dislike the change made in r1696:

Change : Go to the next/previous file in the directory on the user's click on "skip back"/"skip forward";

At least make it optional, because those buttons are usually used for navigate between chapters or tracks, not completely different files. If the current video/playlist doesn't have chapters and the user has disabled this option they should be greyed out IMO.

EDIT: Not to mention that when you accidentally press the key associated with them in your remote or keyboard you change the file too... crazy.

Did you try this option?
Go to the next/previous file in the directory on the user's click on "skip back"/"skip forward" works when only one file in playlist.
Otherwise, they are working with playlist, as before.
If the current video have chapters "skip back"/"skip forward" works with chapters, as before.

Previously, if in the playlist was only one file, then "skip back"/"skip forward" was disabled.

You don't see the right subtitle. You see the 5th subs. I speak about subs one, two and three above the subs number 5.


See for example for the sub number 1 (at the top of the screen):
the subs complete is:
"RSPK syndrome is the conditionwhere in an esper loses control over themselves, causing a subconscious and uncontrllable outburst of power"

in sub cut it lacks "control over" and "outburst of power"

@ikarad
Check "Position subtitles relative to the video frame".
Wait, If you look properly they are both out of the "video frame" because the frame ends at the blue corners of the video. Windowed mode added those black borders that don't make part of the video. if you disable free window resize and then resize the video the subs will now show like the fullscreen screenshot.
the fansubbers missaligned the subtitles.

ikarad: use VSFilter as it's subtitle positioning doesn't vary unlike the internal one which scales according to resolution of the window.

Of course I tried it, otherwise I wouldn't be writing this. That's the exact thing I'm opposing to. I do not want that. If I open a movie that's is in, let's say, a 10 movie folder, and it doesn't have chapters I don't want those buttons active so I can accidentally press them (like I've done today) while I'm in the middle of Iron Man's best scene action to see Transformers' beginning.

I understand this may be useful for folders containing audio files, but for those containing video files is awful IMO. If you guys plan to keep it this way, an option to disable it would be great.

[Astrophizz]

Well it's good for TV series too (and I think that's what it was developed for) but I understand not wanting to hop between files in certain folders.

It already is. What is your language?

Ok, I'll do it customizable.

I need guru's help.
I almost finished a customizable OSD size.
It would be great if a test OSD message displays on change setting.
How to call m_OSD.DisplayMessage from MainFrm in CPPageTweaks.cpp?

void CPPageTweaks::OnHScroll(UINT nSBCode, UINT nPos, CScrollBar* pScrollBar)
{
    if(*pScrollBar == m_OSD_SizeSlider)
    {
        m_OSD.DisplayMessage(OSD_TOPLEFT, _T("Test"));
    }
    SetModified();
    __super::OnHScroll(nSBCode, nPos, pScrollBar);
}

This code, of course, can not be compiled.

Thanks, but mpc-hc sould detect that subtitles are out the borders and cut in fullscreen mode and make a translation at the left of the screen to avoid the cut of subs.
Is it possible to make it?

Thanks, it would be interesting to add an option to choice or not if we want to scale or not the subs at the resolution of the window.

Works, спасиб.

[lateko]

Is there a way to set the subtitle load order to prefer external file above the internal subs?

If not, maybe it could be implemented as a "ext" language which would mean external file without language flag? Or maybe just a checkbox "prefer external"?
