Ah, 2.4Ghz. No wonder. The lack of single threaded performance is the reason why you're seeing such slowness at startup. Anyway, I'll see what I can do.

The reason CUVID and QuickSync offer it is that its just a boolean flag to enable, and not any extra code otherwise, so its an effortless option.

I'm not familiar with DXVA decoding at all so I'm probably completely way off the mark here, but can't you decode and deinterlace in one go before doing the copy back?

It is not that you copy back after decoding and again after deinterlacing but that you double the number of frames needing the copy back if you deinterlace at the same time.

Doesn't this apply for CUVID and QuickSync too?

It does, but like I said, its just one boolean flag to enable deinterlacing there, so even if its not ideal performance, it wasn't exactly effort to implement it.

Hi everyone
Cant seem to get this to work. I got both Win 7 and Win 8.1 x64 laptops with LAV filters installed.
However when trying to play any non avi file with MPEDN it says cannot render and gives no details.

Yes, I get the effort part, just didn't quite understand what you meant by twice the copy back when all deinterlacing algo's if set up equally would require it too. Anyway exactly how much effort are we talking about, do you know?

Did you install x64 LAV filters specifically?

Nope. Installed x86 of both MPEDN and LAV as I want to use MadVR with it.

What non-avi files are we talking about?

Tried different mkvs with avc h264 and also avc mp4s. Some 720P others 1080P.

I got interested in this player and will be reading the 20 pages later today and testing it but while I get home, I was wondering if my only intent is to use it for Bluray rip playback, if I will be taking real advantage of its features.
Also, does it have an upmix from 5.1 to 7.1 like on the latest builds of MPC BE?

Thanks!

Well, no one else reported such problems. As long as LAV can decode the files, MPDN will play them. What you could perhaps try is make sure your LAV filters are setup correctly (i.e. try MPC-HC / BE without internal filters and force it to use external LAV filters).

Yes, Chroma upscaling with SuperChromaRes is by far the best IQ you could get - and you still need to upscale chroma for 1080p 4:2:0 materials (assuming your rips are 1080p). Upmix is easily achieved with AC3Filter (just add it into the audio post processing filter list - I personally use it myself).

Excellent about ChromaRes ! You bet I am directly going to my HT room today to test this.
About AC3Filter..but how does that come into play if I am using lav filters for audio/video and have the dts-hd decoder (TMT).
I guess I am confused on how all those will come together with Ac3Filter to upmix.
Sorry for the noob question

AC3Filter must be setup to accept LPCM / PCM inputs, and also set its output to 7.1, that should be all it takes.

Hi everyone,

The latest Player Extensions now also add shortcuts for rewinding / forwarding playback. The key bindings are similar to those of MPC-HC and are as follows:

• Left / Right: Go back / forward 5 seconds.
• Ctrl + Shift + Left / Right: Go back / forward 30 seconds.
• Ctrl + Left / Right: Go back / forward 1 frame.
• Ctrl + PageDown / PageUp: Load next / previous file in folder.

You can also find this list in the context menu under Play -> Navigation.

When you say Chroma Upscaling and SuperChromaREs...is it one or the other not both together?
Also, there is a Chroma Upscaler option AND there is a ChromaScaler script too so just wondering.
I am reading through the thread now checking for recommend settings as well.
Regards!

So you run MediaPlayerDotNet.exe, MPDN opens up - but you can't click on any of the menus (eg View) for a couple of seconds because the Windows 'busy' icon is showing (the animated circle icon in Win 7, it was an hourglass on XP I think). Once the busy icons goes away, you can interact with the program, but I can't say that I can recall seeing any other programs off the top of my head that show a delay like this at startup.

v2.16.4 Changelog:
    Implemented script caching to reduce start up time

Scripts will get recompiled automatically at startup if they have been updated (based on write time stamp and file size). However, should you suspect that a script is not being recompiled, start MPDN with --flushcache switch and it'll make sure the entire cache gets flushed out, forcing all scripts to get recompiled.

On my i5 dual core 2.5Ghz laptop, the hour glass now only so much as flickers. Profiling the load times of the pre-compiled scripts shows 5ms.

Pick one. Chroma Upscaler will be bypassed automatically when you choose a render script chroma scaler. The beauty of the RenderScript system is that it allows a portion, or the all scaling operations to be replaced.

For example, if you have just SuperChromaRes in your render script, you'll still have to rely on MPDN's luma upscaler / downscaler to get you to the target size. You can bypass MPDN's upscalers completely too if you choose SuperChromaRes -> SuperRes. This of course would still rely on MPDN's downscalers.

Hi Zachs, I have exactly the same issue but using MPDN x64.

Both x86 and x64 LAV filters installed, MPC-BE+madVR+LAV filters combination works fine but MPDN just won't open any videos giving a cannot render file error message with no further details.

Will try the x86 version later and report back.

[Zachs]

Have you tried what I said in regards to disabling internal filters with MPC-BE?

If that works fine, enable debug dialog in options, and click on details button when the error occurs and paste the stack trace and error messages here for me please.
