Integration of MPC-HC subtitle's engine (2 Viewers)

[mortstar]

This seems like great work, I haven't implemented it yet.

Does it mean the MPC-HC codec is now built in to MediaPortal or is it just a specific subtitles filter, that allows whichever DXVA compliant codec being used to continue using DXVA?

Should DirectVobSub be uninstalled?

 

[cpp2005]

Maybe cpp2005 should provide the slider in the patch or maybe he should join the team...

Good idea

Indeed, 500ms is too much for lip sync correction. Even blind persons see 0.5 second sync difference I would go down as far as 175 ms, or even 100 ms.

I guess it need to be configurable (the problem with small interval that in case of big delay you need many key presses to get it).

Exactly, you may uninstall DirectVobSub (but you don't have to).

Synch problem with evr has been solved.
I check divx file (so sw mode) and dxva mode with mkv 720p. h264. 25fps and 23.976 fps no problem at all.

good work

Could be be usefull install and configure the Deja VU fonts as MP default for the new awesome subtitles library
(imho the serif version is the best choice for subtitles)

DejaVu it's the Open Office default fonts.

Maybe you could apply the same step mechanism as used in forward/backward skipping (15s, 30s, 1m, 5m,...)?!

Anyway, many many thanks for making this whole thing happen

I have tested the patch and it works fine. But... on some files the included subtitles will not be displayed with the same font like with Directvobsub. In some cases the fonts are so small I even can't read it. Other files I tested works fine though (uses the embedded fonts in the MKV correctly). It seems the subtitle engine from MPC is not as good as DirectVobSub?

With this new features MP need to disable postprocessing filter when a dxva filter is find out into the filtergraph?

Now if I've ffdshow in postprocessing filter (h.264 disable, raw video enabled). Can postprocessing filter be disabled on a dxva filtergraph?
with a new option in the postprocessing tab ("disable all filter on dxva based filtergraph"). this option make be possibile to configure a postprocessing for other codec as xvid/dvix.

A DXVA codec must be directly connectded to the renderer, if there is any codec connected between the video codec and the renderer (DirectVobSub, ffdshow PostProcessing) then DXVA will not apply.

On a seperate but related note: I have read that CoreCodec are developing CoreAVC to use CUDA on nVidia cards so that all supported videos playback with GPU acceleration (much better than DXVA!)

A liitle bit overkill for this problem, but it will definitely solve it

DirectVobSub is based on exactly the same code (it's part of MPC project). So they should have the same features/bugs it is possible that I missed something, so if you can upload it somewhere, I will check. Just to make sure, did you select bigger font in mediaportal configuration?

With this new features MP need to disable postprocessing filter when a dxva filter is find out into the filtergraph?

I understand that it can be usefull, however it is very difficult to know whether dxva is used. An alternative option could be "Don't use post processing for HD".

A couple of issues with the CoreAVC solution:
- No solution for ATI cards unless ATI implements support for CUDA
- There's a reason CoreAVC is the best performing software decoder: it does so by compromising quality. On my 58" screen I can see a visible quality difference between CoreAVC (software) and MPC Video Decoder (DXVA).
