Alright I've been playing around with MPC-HC 1.7.9, AviSynth+ and SVP 4.0.0.60.

It has been surprisingly very stable but I just got a freeze after playing videos about 20 videos without issue. The freezes only happen when loading videos.

Then I'm loading AVS scripts instead of opening the video file directly; I'm not sure if it would still crash if I open the video files directly.

EDIT: I've got another crash when loading a video directly. Still totally random, but it always happens when loading.

I think 2.6 wasn't crashing so much on seek, but would still sometimes freeze when loading videos.

Every now and then, MPC-HC process needs to be killed and re-opened.

Then I'm also loading the video through an AVS script to re-tune to 432hz instead of opening it directly which adds to the instability.

Edit: I think you're right. 2.6 doesn't crash on seek. Only on load.

2.6 MT is considerably more stable than 2.5, but it would still freeze now and then. Just a LOT less.

I don't think I've ever seen SVP without that bug. Perhaps there's a configuration combination that minimizes it but I haven't got that configuration.

Chainik, how complicated is ffdshow? As I understand it, it's an old piece of code that is totally unmanageable and is dead since long, and it does a whole bunch of things. Just to do the AviSynth integration, would it be very difficult to rewrite a "ffdshow lite" that does just that in the simplest and most stable way?

The crashes and freezes appear to be the same with AVS+ than with AVS 2.6, so it would make sense that the bug is in ffdshow and not related to AVS.

I will also add at the new AVS+ initializes considerably faster.

In my Natural Grounding Player, when playing at 432hz, I edited the script to repeat the first frame for half-second to fill up the buffer to avoid lag on start. It's working pretty smooth!

Here is VERSION 4.0.0.60 via Chainik

OK thanks. As a first try, the video INNA Endless was still stuttering. But if I open the file directly without going through the 432hz re-attunement script, then it plays perfect. So in that one case, it's because of the AviSynth filter reading the source file too slowly.

I'll play around with this version and see if I encounter any problem.

The new AVS+ requires Visual C++ Runtimes 2015. Try installing that.

How can I download and install older versions of SVP?

It appears some videos are pre-disposed to choppy playback. I came back to the one video that was really choppy, and it's choppy again, while every other video were fine (2 were choppy temporarily and then played fine). This one is 1920x1080 25fps... nothing special

OK I've been watching videos for 1h30 and it's been surprisingly smooth. Only 2 videos got choppy (both were 1080p). One was unwatcheable until it stopped chopping off and the other one was choppy for 15 seconds and then recovered normal playback. You say v4.0.0.60 doesn't have that issue? mmm

This bug has been around for a while but now it has to be fixed somehow. Everything else is working very smooth with this AVS+ version but this bug got worse when it happens.

Btw, when I increased the amount of threats, it might have increased the frequency of this bug. After setting the thread count back to auto, everything got smooth except a few random rare exceptions.

I know it's frustrating when there is a recurring bug and we can't figure out why the heck it's happening. In my Natural Grounding Player, each video starts the playback twice and I tried figuring out why several times and could never fix it... uh...

As per official documentation

mpv: disable angle
Broken shit, not worth wasting my time with.

LOL!

I've been watching a bunch of videos without a single frame delay.

The only videos that have problem are sometimes 1080p videos, whether displaying on 1080p TV or 768p laptop screen.

It will stop for half-second at a time and the continue when the CPU is clearly not at 100%.

This is also the version with the best audio/video sync. With AviSynth+, I can finally re-tune audios from 440hz to 432hz with TimeStretch while keeping a perfect sync. With AVS 2.6, I had to instead slow down playback slightly to keep perfect sync. Which caused repeat frames when playing videos that were already 60fps.

2.6 sometimes get a "little bit" choppy, but the effect is much less worse. I believe it's the same bug but the side-effects are handled differently. Perhaps it's even happening more often with AVS+.

Here's some more choppy playback

Too bad, because besides these "choppy playback" episodes, it's working perfect.

Oh, and the greatly reduced memory usage makes the x64 memory leak more manageable smile

117

(46 replies, posted in Using SVP)

Since memory usage is much lower, it's safe to increase the amount of threads. I find that manually increasing it to the max (23) makes it a little bit more stable.

Overall, it appears to be working better than 2.6 except when it falls into this "mode" where CPU usage jumps up and down. It may be the same bug as in 2.6 where sometimes playback would get choppy for no reason but with AVS+ the bug's effect is worse.

Btw, I used to run PerfectDisk and it would run in the background while playing video and cause lags, so I disabled that.

Sometimes the playback gets choppy with CPU usage going up and down, not sure why.

The middle part of the graph is while playing a 1080p video, and strangely enough, after saving a first screenshot, then it started playing smoothly and I've let it keep playing smoothly (last part of the graph). Not sure what happened.

New version r1847 is working well.

Here's a performance graph comparison

AVS+

AVS 2.6
http://s20.postimg.org/5h2hz7v89/Avs26.png

CPU usage is about the same, the first second of playback "might" be a little bit choppier, but the memory usage is TWICE LOWER!!

It seems to be working well so I'll play around with it and see how it stands.

It also "feels" a little bit smoother but such details are hard to know for sure, it can just be me.

Edit: It seems to be more stable at high CPU usage instead of randomly lagging.

How is the VapourSynth version going? I suppose it's more stable than the AviSynth version? Any drawbacks? VapourSynth itself is still young.

Edit: madVR doesn't work with mvp and Madshi doesn't seem interested in supporting it

OK I just tried it myself (x86 version). It says it's running but it doesn't appear to be doing anything at all and the CPU usage remains low.

Somehow it's not hooking up properly into the rendering chain.

I might mention it here although I don't know whether it has been fixed already.

Some time ago, I manually updated the madVR folder with a newer release. Afterwards, SVP said there was an updated version of madVR but failed to update. There was no way to get the update to work. The only solution was to copy back the original folder of madVR (luckily I kept it), and then let the update manager update it from there.

Listing the specific crashes and instabilities would be useful.

I have to say I did also have some instabilities and I haven't always reported them.

AviSynth+ r1841 has been released on April 7th.

Has anyone tried it yet with SVP? What difference are you seeing?

The person who developed the KnlMeansCL AviSynth filter had originally written it for OpenCL 1.1, and eventually migrated it to OpenCL 1.2 saying it gave about a 20% boost.

Would SVP get a 20% boost by using OpenCL 1.2 instead of 1.1?

However, OpenCL 1.2 is a lot less compatible than v1.1; I think supporting both is important.
