Potplayer - Direct Interface

any lines in the log?

so what? I see everything works until you close PotPlayer

something odd seems to be going on here....

with direct mode:

- svp icon in taskbar shows a video is active
- svp osd does not display at start of play
- the svp graph in the svp control panel shows 10%-15% load
- windows task manager shows 15%-25% cpu and gpu load
- madvr shows 0 dropped frames

using ffdshow raw video filter:

- svp icon in taskbar shows a video is active
- svp osd does display at start of play
- the svp graph in the svp control panel shows 90%+ load
- windows task manager shows 70%+ gpu load
- madvr shows rapid dropped frames

what would cause such a huge difference in performance?

I would try vapoursynth (avisynth = false) and tell more about video you try to watch (HDR/4K?)

yes, turning off "prefer_avisynth" (false) was one of the first things i tried, didn't solve the problem, i also tried turning on / off avisynth and vapoursynth in potplayer (preferences > video ), and that didn't work either....

i'm using madvr as my video renderer and lav filters, dxva2 (copyback).... doesn't matter if i play hd files or hdr files, same thing happens, clicking the svp taskbar icon shows "1 active video playing at 59.94 fps [x5/2]" and indicates the correct profile i set up, but the video doesn't have svp applied, nothing happens.

if i set "potplayer native" to false and use ffdshow raw video filter, everything works as it should, except i can't no longer use madvr for hdr, even with madvr set to hdr passthrough.

so i reset all of the filter control settings in potplayer from lav to "built-in decoder (recommended)" and everything is working as it should with svp direct, in fact svp direct now works with either avisynth and vapoursynth, just a matter of setting "prefer_avisnth" to true or false in utilities settings....

so, a couple of question:

- does it matter which one i use, avisynth or vapoursynth, is one better than the other?
- am i missing out on anything by not using lav filters?

thanks!

after some more testing i've found that "prefer_avisynth = true" displays strange colors (over saturated / over contrasted) when i play hdr files only if "try to recover hdr colors (directshow)" is enabled...

with "prefer_avisynth = false", enabling or disabling "try to recover hdr colors (directshow)" has no impact, the image remains the same with either setting, and it looks the same as  "prefer_avisynth = true" with "try to recover hdr colors (directshow)" disabled.

as mentioned earlier, i'm using madvr (hdr passthrough) with svp / potplayer.

Hi

last evening I noticed that MadVr no more indicates an 8bit conversion in the status, and SVP also outputs the correct values in the report.
By looking to the changelog of Potplayer, there is a note: "Improved 10-bit output processing"

"Looks like a bottleneck somewhere inside PotPlayer, probably in 8bit->10bit conversion (because ALL the video filters including Avisynth are 8-bit only)"

Is it possible, that 10bit is now working? or are the reportings wrong and only 8bit is displayed?
Is there a to measure the displayed content?

I'm using Potplayer with Native Interface (PotPlayer, Avisynth, MadVr, SVP)
Using Potplayer's Internal Filters with DX11 Copyback.

thanks

> not possible, not only because SVP's plugins for Avisynth supports 8-bit only, but because nothing changed on PotPlayer's side

Sad, then PotPlayer, MadVr and SVP's reporting is wrong.


I assume that somewhere some kind of dithering is active, even i deactivated it everywhere?

Is there a Player which works with both, SVP and MadVr without these limits?
The thing is i need MadVr for the Display calibration (3D Lut) and have not found an affordable alternative.

Maybe does someone here know a good alternative?
