Topic: Stutters on starting playback and after seeking

Hello again SVP-Support smile

Maken, thank you for that nice updated PotPlayer-Guide which I have followed strictly.

Having stayed for almost a year joyful on SVP and changed now to v4 I was hoping that my little problem disappears. But it's exactly the same as with v3.
Video & Audio always judder/stutters on start of playback after seeking and on first start of any video for ~2 sec.
No matter if I seek only once or repeatedly and how much time elapses between it.

Maybe it's normal?

If I only switch between play and pause, there is no problem.



My Rig is still the same:
Motherboard: Asus Maximus VI Gene C2
CPU: Intel Core i7-4770K, 3500 MHz
GPU: MSI GeForce GTX 780 Ti Gaming 3G
RAM: G Skill TridentX F3-1600C7-8GTX   16GB Kit
Drive: Samsung SSD 840 EVO 250GB
Sound: Creative Sound Blaster ZxR
OS: Microsoft Windows 8.1 x64 Enterprise N
Monitor: Asus VN279QLB @60Hz or @74Hz on DisplayPort

In NVIDIA Control Panel: default settings (0-255 dynamic range)

Software constellation:
SVP 4.0.0.72 Free
PotPlayer 1.6.59285 Beta or PotPlayer 1.6.58613
AviSynth MT from SVP4-Installer or AviSynth MT 2.6.0 MT 32bit
ffdshow 1.3.4533
LAV Filters 0.68.0
ReClock 1.8.8.5

I tried some settings:
- madVR not used
- GPU acceleration - on/off
- Assume double frame rate for interlaced video - on/off
- reset on seek - all settings
- Outer lightning - on/off
- Fill black bars - on/off
- ReClock - on/off
- Default SVP settings and some other settings like setup, performance, seek, target
- Other Video-Render
- Also tried on fresh installed Windows 10 Pro x64 PC, but same


For any help or ideas I would be very grateful!

Yuuko
Did you try madVR with settings - rendering:
- enable: delay playback start until render queue is full
- enable: delay playback start after seeking, too

Then you must to get some delays after seeking but without any stutters.

HI MAG79 and thanks for feedback

Actually I don't use madVR.
But now i've installed v09015 and set it as Video-Render with the recommended settings - the stutter is much stronger/longer now

Re: Stutters on starting playback and after seeking

Your hardware is definitely more than capable. Why it's stuttering more with Madvr doesn't even make sense (since that uses only your GPU and with Madvr's default settings it should be a breeze for your videocard).

I have a few questions to ask:

What Operating System are you using?
How long have you been using it for without a clean format?
What other "media players" have you tested?
Are you getting your LAV Filters and "codecs" via a codec pack or are you getting them from their official sites/locations?

Re: Stutters on starting playback and after seeking

Hello Blackfyre !

I'm still on Windows 8.1 x64 Enterprise N, but already tested it on new installed, more powerful PC with updated Windows 10 Pro x64  -  same result
And also could notice it on two other AMD/ATI computers.
Different player has not been tested because I don't intend to use another videoplayer - other users have also not this problem with PotPlayer
LAV Filters and any other related x86 software I've downloaded from official sites.

That issue is there since I use SVP and I could fix it yet - but also thought that it is common  ( :
I followed the Guide and also looked for solutions and settings on other sites...
