i mean in Quality

Both can render at display resolution so there should be no visible difference. Performance can differ (sometimes XySubFilter is faster, sometimes ISR) and some bugs are different. Differences are mainly relevant for ASS subtitles.

Wasn't it "always" available? Is your sample 8 bit? Current internal LAV does not allow HEVC 10 bit using DXVA2 native but external nightly already has it activated. So it should be available in MPC-HC in the near future if the renderer supports it.

Yeah my source was 8-bit I just checked with my anime 10-bit source I still need dxva-cb to play that back using hardware acceleration. It's nice to know I won't need to do that soon though thanks.

dxva is bad for anime and hi10p

I'll try it out during the weekend.

So, I managed to do it (talk to MadVR), it wasn't hard at all, but there's a caveat (see at the end).
I'm using Windows Host Script (which comes with newer Windows, >Win7, I think), which should be run with 'cscript.exe':
- cgi script receives 1 url encoded argument (the keystroke), url decode it, then send it to the foreground application.

MPC-HC web interface setup:
- x Serve pages from: ./webroot
(we don't have to change Default page value (default is: 'index.html;index.php'))
- CGI handlers: '.vbs=c:\Windows\System32\cscript.exe'

Save this into file called 'sendkeys.vbs' in 'webroot' subdirectory of directory of MPC-HC (you don't have to deploy anything else to here, all the other pages will be served as well if you need them). The file extension does matter!

'!c:/windows/system32/cscript //nologo
' Toggle source level in MadVR (CTRL+SHIFT+ALT+i = ^+%i = %5e%2b%25i)
' get shell object
Set WshShell = WScript.CreateObject("WScript.Shell")
' get Process array that includes the query string
Set wshUserEnv = WshShell.Environment("Process")
' urldecode querystring
param = unescape(wshUserEnv("QUERY_STRING"))
' send keystroke
WshShell.SendKeys param
' delete used objects
Set wshUserEnv = Nothing
Set WshShell   = Nothing
' quit script with exit code 0
Wscript.Quit 0

You can try it out from a different computer or from a smartphone by calling this URL (you should modify the IP/port):

http://192.168.1.6:13579/sendkeys.vbs?%5e%2b%25i

Issues:
- since it can only send keystrokes to the foreground application, and I don't include a check whether it is MPC-HC (i tried, and it worked, but it was so slow, that the whole thing became unusable), so you can get some funky stuff

Good thing:
- it won't kick out MadVR from Fullscreen Exclusive mode

Can I have a feature request to implement this sendkeys feature into MPC-HC's web interface itself? (if it's not hard to do.) In that way we can circumvent the foreground limitation.

PS: So I finished modifying Remoti.co Lite Android app (without having the source code, just some silly skinning remained), if somebody interested in it, I can upload it somewhere.
- added 2 buttons for subtitle delay
- added 1 button to change source level with MadVR
- fixed and refactored the after playback entries
- modded the default skip interval from 5 sec to 10 sec
- switched the size and location of the FF/RW with PrevTrack/NextTrack buttons in portrait mode, since we use them more frequently
- added new skin(s)

I can't really tell the difference tbh. I've tried madvr and KCP and the difference was always very minimal.

Hi guys,


to use with MadVr is it better to Install MPC_HC 32bit or 64bit?

thanks

[kasper93]

As far madVR is concerned there shouldn't be any differences. But 64bit MPC-HC is preferable, because it has better performance for HEVC and other demanding codecs.

x64 build of LAV would appear to be quite a bit faster for h264/h265 decoding

Is there a way to implement an option to take screenshots in display aspect ratio? I think the screenshot function is used far more often as "I want to have this picture," than, "I want to compare unresized samples," and being able to have a properly sized screenshot of anamorphic content would be great. I don't have a single DVD that's meant to be displayed at 720x480, yet all my screenshots are like that.

[LigH]

The screenshot is usually taken from the decoder, which did not yet resample the result to the target aspect ratio. This is technically rather simple.

Taking the image later is more complicated. Some renderers don't allow reading back the image (e.g. "Hardware Overlay" is write-only), but the scaling may be done by graphic API functions (if they support displaying anamorphic textures with a target aspect ratio), so even if it is possible, it may be slow. It may be necessary to scale it independently of the video output in the player, which requires additional calculation time.

I believe everyone who's used to take screenshots would agree to pay some calculation time for getting screenshots with the proper AR.

This is a contradiction. (I think renderer controls it.)

[vivan]

If image is downscaled when you're taking screenshot using madVR - it will save it downscaled. It might bug but it proves that renderer have full control over processing screenshot and its size.

[kuchikirukia]

Yeah, but madVR != all renderers.



(Also, it doesn't seem to do that anymore.)

If it'll work with all renderers that would normally allow you to take a screenshot, great!

To take screenshot can be done from a video decoder, video transform filter and any renderer that supports capture. Generally, it's only possible to capture what you see in video renderer. AR correction (processed) image can be acquired via the capture from a video transform filter (available in potplayer).

[GCRaistlin]

Is it possible to change the balance between L/R audio channels in MPC-HC?

[vivan]

It's in the Playback section of the options.

[Megalith]

Can someone explain what "Limiter" is under "Processors"?

[Snowknight26]

Probably the function that detects and prevents clipping.

[Jamaika]

Is it possible to read write RTF (Rich Text Format) by the player MPC-HC in the description of the Matroska container? How can I use the "Text Formatting Elements and Color" in the description?
