Topic: Ffdshow Problem: No AviSynth filter available (slow playback)

Is there something wrong with my installation? Everytime I want to play a video with "Smooth motion" support I have to reconfigure the "ffdshow raw video" filter after the playback started.
In the "ffdshow raw filter" properties window there is a "Show/hide filters" section (Reachable in MPC-HC through: <right click>->Filters->
ffdshow raw video filter>Properties...). In this section you can find two lists. One empty list called "Available filters" and another list called "Visible filters". I have to
put the "AViSynth" filter from the "Visible filters"-list to the "Available filters"-list. Otherwise I get very laggy output - It looks like smooth motion - with that
"SVP ...slow performance (SVP index: 0.63 - 0.80)" message on the OSD. There is no such problem with the "AviSynth" filter in the "Available filters" list. I get smooth playback
with a SVP index of around 1.0*.

I also configured the "ffdhsow raw video filter" in MPC-HC while no video file is beeing played (Under Options->External Filters->ffdshow raw video filter). The "AviSynth" and
another filter I choosed appear on the "Available filters" list - even if MPV-HC is restarted. If SVP is beeing initialized it looks like the list gets overwritten and SVP runs with very bad performance.

It is very strange. It shouldn't to be.
Can you show your filter's list while playback? Take screenshot of menu: MPC-HC - Play- Filters

Thank you very much for you reply. I had a little problem with the "Snipping Tool" and used "Copy filters to clipboard" instead. Here is the filters list from "MPC-HC - Play - Filters":

Filters currently loaded:
  - Default DirectSound Device
  - Enhanced Video Renderer (custom presenter)
  - Audio Switcher
  - ffdshow raw video filter
  - LAV Audio Decoder (internal)
  - LAV Video Decoder (internal)
  - LAV Splitter Source (internal)

You could have just used your keyboard's "Print Screen" key...

Maybe you can choose different setting?

In my case, I don't add ffdshow raw video filter as external filter but instead I just enable Raw video to be processed by ffdshow.

Avisynth must be in visible filters list in ffdShow. Otherwize SVP can't work with it. So you need for some tuning and customizations.

Thank you for filters list. I see now. What you can do to get smooth playback:
1. Enable HW decoding. Click on LAV video decoder in filter list while playback. What you see in the line 'Active decoder' in Hadrware Acceleration settings?
Select CUVID or DXVA2 (copy-back).
2. Enable D3D FullScreen. You are using renderer EVR (custom presenter). It can show jerks in some cases. To make playback more smoothly go to the MPC menu: Options... - Output - Enable option D3D Fullscreen - OK. Reopen video, switch to fullscreen mode (alt-enter).

"SVP ...slow performance (SVP index: 0.63 - 0.80)" message on the OSD
It is mean CPU load or GPU load are close to 100%. SVP settings are too hard to you configuration.
3. General advise is to reset profiles: SVP - Video profiles... - Reset to defauls - OK - Yes.

4. If problem still here can you look to CPU load value (in SVP Performance Graphs window or in Task Manager) and GPU load (in GPU-Z)?

I changed my configuration to reflect the behaviour you just introduced to me. I also had to adjust the "AviSynth" Format in that configuration window. It was set to disabled.

MAG79

HW decoding is already enabled. This is what I see while playing back a video file:

Hardware Decoder to use:
[NVIDIA CUVID ] Active
Active decoder: cuvid

"D3D Fullscreen" is also already enabled.

Here are some interesting observations:

If I put "AviSynth"  on the Available-filters list in the "Show/hide filters"-ffdshow decoder configuration window while playing back a video I have an average CPU workload of 20%. If I do nothing it is about 45%.

45% with SVP processing and 20% - without SVP. roll
You can check it by disapearing of SVP Tearing test line (orange moving line over video).
Press while playback Ctlr-Win-T, you will see the moving line. It is mean SVP is working. Then hide avisynth filter in ffdShow. Do you still see the moving line?

Do you have latest NVIDIA driver?
If yes, have you enabled the CUDA?

MAG79 has already pointed when someone experienced bad playback in this post.


Btw, getting ~45% when playback using SVP is pretty much normal in my case.
Without SVP, it downs to maximal 20% (usually 13%-17%), when using DXVA it's only 2-3%

I must recommend against doing this - another user on this very forum was recently having problems with high CPU load until he switched from CUVID to DXVA2 (copy-back).  In my experience Intel QuickSync is a better alternative if you need such a thing.
