60FPS Frame Interpolation Problem

[lubuntulux]

Hi there!

I have recently stumbled upon mpv's frame interpolation functionality and cannot seem to make it work. http://www.reddit.com/r/linux/comments/2u3bpw/mpv_ver_073_can_interpolate_videos_to_60fps/ https://launchpad.net/~mc3man/+archive/ubuntu/mpv-tests

My setup: Lubuntu 14.04 , nvidia-352 xorg, GTX 750 TI, i3 4330, compiz and 42" Bravia TV Mpv (ffmpeg version), ffmpeg and x264 have been downloaded from mc3man's ppa as instructed by the post.

I have also used every code variation suggested by the OP and other members, both in the mpv.conf and directly from the terminal with -- .

For example:

vo=opengl:smoothmotion:smoothmotion-threshold=0.0 hwdec=no display-fps=60

I constantly get the following mpv output when I run it:

"[vo/opengl] Warning: option smoothmotion was replaced with interpolation and might be removed in the future. [vo/opengl] Warning: option smoothmotion-threshold was replaced with tscale-param1 and might be removed in the future."

I generally cannot detect a difference in image behavior with the interpolation option on/off.

I have also tried disabling composite.

Could I be missing some packages or depdencies, necessary for mpv to function properly? It's really frustrating since a lot of people seem to have been able to set it up.

Hopefully someone can help me out.

I'm not immediately sure what could have gone wrong.

Holy shit that reddit thread is full of misinformation.

[vo/opengl] Warning: option smoothmotion was replaced with interpolation and might be removed in the future.

Well yes, “smoothmotion” doesn't exist anymore.

I generally cannot detect a difference in image behavior with the interpolation option on/off.

You could try posting a log with mpv -v --msg-level=vo=debug. Apart from that, there's nothing I can do to help you without knowing more specifics.

Could I be missing some packages or depdencies, necessary for mpv to function properly?

No, it requires no external dependencies.

[haasn]

What I meant was: You need to use those options while actually playing back a file.

[lubuntulux]

Here's the log of a 1080p mkv: http://textuploader.com/n3cb

[haasn]

Seems like it was working fine, at least until you paused.

[lubuntulux]

Can I use the debug command in conjunction with an interpolation parameter, in order for you review that log as well? Is it possible for you to determine anything from the previous log, in terms of why interpolation isn't working?

[lubuntulux]

Could it actually be, that interpolation is working, while my understanding of the process and subsequent image result and behavior is simply flawed?

I am comparing the output and "smoothness" to SVP on windows.

When using the interpolation command, the image is clear and smooth, as if I had turned down the refresh rate of my monitor to 24hz, in order to match the fps of the mkv, which is what I normally do on Linux. My monitor is set to 60hz, though. I should also note, that the image looks exactly the same, when not using the interpolation command.

However, it certainly does not seem to have achieved the level of smoothness one would expect from 60FPS video, regarding SVP etc.

[Argon-]

SVP and mpv's interpolation are not the same thing: https://github.com/mpv-player/mpv/wiki/Interpolation So comparing them is not really useful.

[lubuntulux]

Thank you for that link.

I understand, that it does not use the same interpolation process as SVP, hence producing a different image and behavior, however it still does not look anything like 60FPS video.

What else can I do to figure out this problem? I have read that people downgraded mesa in order to run mpv's frame interpolation properly. Could it be a problem with my kernel or version of Ubuntu?

I am quite stranded here.

[lubuntulux]

@haasn: Hab grad gesehen dass du ein Deutscher bist.:-) Du scheinst mir wirklich Ahnung von der Materie zu haben, und ich möchte es mir einfach nicht antun im unfreundlichen ubuntu DE Forum nach der Antwort zu betteln.

Fällt dir nichts mehr ein?

[haasn]

the image is clear and smooth, as if I had turned down the refresh rate of my monitor to 24hz

Sounds like it's working as intended then.

[lubuntulux]

Yes, but the image looks exactly the same when I do not enter any interpolation parameters, which leads me to believe, that it isn't working as intended.

What else could I check for? Any other logs or data to provide?

[haasn]

You are playing back a 24 Hz file on a 60 Hz monitor with interpolation turned off and it looks just as smooth?

[lubuntulux]

Yes, exactly the same.

When I just enter mpv /file path it looks the same as mpv --vo=opengl-hq:interpolation /file path. (If not slightly better).

[lubuntulux]

The image actually seems slightly smoother and displays less judder when I don't use any interpolation options.

Without interpolation options, it is as if I had turned down my monitor's refresh rate to 24hz, in order to match the file's fps, which is what I normally do with other players, so I know what it looks like.

When I turn it on, there is clear judder and lagging during panning shots and fast scenes, which does not occur when disabled.

[ghost]

The image actually seems slightly smoother and displays less judder when I don't use any interpolation options.

Maybe your GPU is too slow.

[lubuntulux]

I strongly doubt that, seeing as I use a GTX750TI. My CPU (i3 4330 Dual Core) usage stays below 10% and GPU usage below 7% when interpolation options are added. The process is not initiated, and I simply cannot figure out why.

You have advised another member to verify whether vsynch might be occupied by compiz and hence unobtainable for mpv to use. I have SynchToVBlank enabled both in my Nvidia-Settings and Compiz, and will try to turn it off in the latter.
I have also edited my xorg.conf in order to enable Performance Mode and TripleBuffering. I will try to disable those as well.

Edit: DIsabling SynchtoVBlank or Composite and OpenGl settings in compiz did not help. Also disabling Triplebuffering and performance mode had no effect.

Do you have any other ideas?

[lubuntulux]

Here the output when I add an interpolation option: Interpolation isn't even mentioned.

[lubuntulux]

This guy seemed to have the exact same problem and hardware. https://github.com/mpv-player/mpv/issues/1645

He stated, that he solved the problem with " vaapi-copy+opengl" and later on the 0.8.2 version of mpv. (What does he mean by that?)

Quote: "i managed to test another system, it is an i3-3110M with an intel HD4000 on board. While it confirmed my old findings (vdpau+opengl:smoothmotion not working), i managed to try vaapi-copy+opengl and there smoothmotion worked (even with the hq preset), while it failed on vaapi+opengl"

He also mentioned an additional parameter "speed", that made my video look exactly like 60FPS, without any skipped frames, judder or lag at all. --hwdec=vdpau --vo=opengl:smoothmotion --speed=2

[haasn]

You are not even using hwdec, so I highly doubt it's the same problem.

[ghost]

If you play a video with mpv --no-config --speed=3 file.mkv (this is with interpolation disabled), do you see any framedrops?

[lubuntulux]

@haasn: I have tried all variations, including hardware acceleration on/off.

@wm4: with mpv --no-config --speed=3 file.mkv the image looks 100% smooth, without a single dropped frame or judder. It seems interpolated and exactly like 60FPS. (Obviously, sound and video are still accelerated, though) The same occurs with speed 2, while again no frame skipping, dropping or judder.

jackson@jackson:~$ mpv --no-config --speed=3 /tmp/ramdisk/abc.mkv

[ghost]

with mpv --no-config --speed=3 file.mkv the image looks 100% smooth, without a single dropped frame or judder.

This sounds wrong. If the file is ~23fps, the screen is ~60hz, and it worked as intended, it must have dropped frames. Which means the GL driver apparently doesn't block on vsync, which breaks the entirely logic mpv's interpolation code is relying on.

[ghost]

Dropped: 715

Actually.. it does drop frames. Why did you say it doesn't?

[lubuntulux]

I saw that too, but it really looks like not a single frame is dropped. Absolutely no lag or judder, that would indicate frame dropping. Either the output is flawed due to an error within mpv, or something is causing it to output false values.

What did the fact, that increasing the speed lead to smooth image behavior, tell us?

[lubuntulux]

I ran --msg-level=vo=debug to check if interpolation was actually active. "interpolation queue underrun" keeps popping up.

[vo/opengl] interpolation queue underrun

That looks bad?

[lubuntulux]

What does that mean, or rather, what is it caused by? I read in another post, that "interpolation queue underrun" is considered a normal occurrence with tscale and oversample.

Could it be the cause of lacking smoothness in this interpolation case, however?

[ghost]

that "interpolation queue underrun" is considered a normal occurrence with tscale and oversample.

Could be. I don't even know how this works. I just thought I'd point this out since it looks kind of suspicious. And also, you edited your post (and added this log), so people who use email notification won't realize it was added.

[lubuntulux]

OK, I will post it again.

Here is the glxinfo: http://textuploader.com/w9wd

And here the log of an mkv file with interpolation: http://textuploader.com/w9pn

Thank you very much for the time you have invested so far, but this problem really drives me insane. Especially because so many people seem to have set it up successfully.

Is there anything else that I could provide in order to increase the chances for this problem to be solved?

One thing you can try tscale=mitchell and seeing if you still get any interpolation queue underruns. That mode of operation should in theory cause none, and it would also be much easier to debug than tscale=oversample.

Apart from that, it still looks like it should sort of be working correctly.

@haasn:tscale=mitchell has eliminated the judder that would occur with interpolation. There has definitely been an improvement in image quality and smoothness, however I still don't feel that 60FPS are being displayed.

It now seems like a a perfect 24fps on 24Hz representation, however not interpolated 60FPS imagery.

I now have an idea why interpolation might not work. Here my version of mpv: mpv git-72808be (C) 2000-2015 mpv/MPlayer/mplayer2 projects built on 2015-06-17T02:56:57 ffmpeg library versions: libavutil 54.27.100 libavcodec 56.41.100 libavformat 56.36.100 libswscale 3.1.101 libavfilter 5.17.100 libswresample 1.2.100

In the reddit post, the OP states that interpolation is a functionality exclusive to the 0.73 version. http://www.reddit.com/r/linux/comments/2u3bpw/mpv_ver_073_can_interpolate_videos_to_60fps/ The version that is available to me from mc3man's ppa is far more advanced than that. Could the newer version be the problem?

I will purge the current version, install 0.73 and report later this evening.

Thank you very much so far, tsacle=mitchell definitely helped!

“Sounds like it's working as intended then.”

[lubuntulux]

So why doesn't it work the same way with interpolation? I cannot seem to find a significant difference between the tscale and interpolation command.

The "mitchell" option must be the cause of this sudden change.

Would you mind to elaborate?

[haasn]

Interpolation just turns it on or off, tscale changes the interpolation method used. (This is all documented in the manual, by the way.)

[lubuntulux]

I have read the documentation multiple times. Am I correctly assuming, that in order to achieve true 60FPS interpolation, the likes of SVP produce, I need to get into vapoursynth and mpv?

The interpolation method in question here, simply displays a lower fps file on a 60+ hz screen, as if the refresh rate had been reduced to match the file's?

[haasn]

Yes to both

[lubuntulux]

Well, thank you very much so far.

I have read that mitchell seems to invoke an inferior interpolation method, which is less demanding.

Is this true?

[haasn]

No, mitchell is somewhat more demanding than oversample and in my opinion also much better (smoother).

Some users dislike the extra blur/fringing it introduces though, which is why oversample is the default - in part also due to backwards compatibility (oversample was the only mode of operation from back when it was called smoothmotion instead of interpolation).

[lubuntulux]

It also works fine with oversample, which I too, as you have described, consider to be clearer.

After some experimenting I have settled with these settings: mpv --vo=opengl-hq=scale=ewa_lanczossharp --hwdec=vdpau --fps=60

I find ewa_lanczossharp to be the sharpest, clearest and smoothest filter. It also seems to be the only one that causes 18% CPU and 15% GPU load. ewa_lanczossharp only works with scale though, an error occurs when I attempt to use it with tscale.

Any final suggestions for improvements and more testing? In case there is an even more demanding option and filter I would like to know, since the hardware is there to be salvaged.(Couldn't really find any here, though https://github.com/mpv-player/mpv/blob/master/DOCS/man/vo.rst)

[haasn]

Your posts are not making any more sense. You said oversample was not working, but now it works fine? And suddenly you are using --fps=60? That won't even affect anything unless you're using --no-correct-pts as well..

ewa_lanczossharp isn't even related in the slightest.

[lubuntulux]

I had never used the option scale=oversample before, as I wasn't aware of it. I have only recently found the page with all the commands. interpolation would never work and smoothmotion, which was "replaced" by such, as the output stated.

I experience an even smoother experience with --fps=60, not sure why. I will add --no-correct-pts and see what happens.

[lubuntulux]

Tried this now: mpv --vo=opengl-hq=tscale=oversample --hwdec=vdpau --fps=60 --no-correct-pts

The addition of--no-correct-pts simply speeds up the video, as if I had added the --speed=2 or 3 option. Although, the audio remains at normal speed. And again, the video seems 60FPS smooth, exactly like in SVP.

And in terms of ewa_lancozossharp, it is listed among the filters in the documentation, where oversample and mitchell are noted, as well. https://github.com/mpv-player/mpv/blob/master/DOCS/man/vo.rst "A slightly sharpened version of ewa_lanczos, preconfigured to use an ideal radius and parameter. If your hardware can run it, this is probably what you should use by default."

[haasn]

I had never used the option scale=oversample before, as I wasn't aware of it.

scale is irrelevant. tscale=oversample is the default.

I experience an even smoother experience with --fps=60, not sure why.

[lubuntulux]

--fps=60 + --no-correct-pts affects the image dramatically. This is what I want, as it seems like true 60FPS.

The only problem is, that the video is speeded up. If you could help me slow it down, while retaining the frame count, that would be awesome.

[haasn]

No. There is no such feature in mpv.

[kevmitch]

--fps=60 + --no-correct-pts

to clarify, this by definition will speed up / slow down the video so that one source frame will be displayed 60 times per second. With regard to smoothness it is completely expected that it will achieve ideal results because it forces the source frame rate to match the display refresh rate (assuming it's 60hz). The same result is more conventionally achieved without timing side effects by setting the display refresh rate to the source frame rate (where possible).

In any case, haasn wasn't recommmending that you use it, but merely stating that --fps=60 alone does nothing.

If you could help me slow it down, while retaining the frame count, that would be awesome.

That is exactly what "interpolation" tries to do. It fills in the additional frames needed to display 24 fps material on a 60hz display using one of the various algorithms. However because it has to interpolate those frames, the result will never be as good as just matching the two rates.

[lubuntulux]

Thank you sooo much for all your support guys, please know, that I will relink both issues on the UbuntuForum, since you are awesome and this is guide material. :-)

I have one last question about Youtube streaming. I am running mpv 0.9.2 (vapoursynth enabled) from this ppa: https://launchpad.net/~djcj/+archive/ubuntu/vapoursynth youtube-dl via deb (youtube-dl_2015.06.04.1-1_all.deb) :https://packages.debian.org/sid/all/youtube-dl/download

The same happens when I don't use the vapoursynth script, hence the problem must be elsewhere: jackson@jackson:~$ mpv https://www.youtube.com/watch?v=Z_mf9aCHag8 Playing: https://www.youtube.com/watch?v=Z_mf9aCHag8 [ffmpeg] ?: https protocol not found, recompile with openssl or gnutls enabled.
